DottaandClaude Opus 5.5 ad2304dc88 fix(chat): recover a held conversation turn's answer after a restart (#20204)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - People talk to agents in Agent Chat. The agent's final message
becomes the chat reply.
> - A chat turn can end while its task stays held: a pending approval,
an execution stage or a dependency blocker keeps the status.
> - #20179 made live run completion post that held turn's answer. It
added `conversationTurnAnswered()`.
> - Background presentation recovery still required a
`conversation_turn_finished` decision and a `done` result.
> - If the server restarts between the status commit and the live
presentation, recovery skips the held turn. The person never gets an
answer.
> - Restarts are product failures. A committed answer must not be lost.
> - This pull request makes recovery use the same answered rule as the
live path, through one shared helper.
> - The benefit is that a held turn's answer reaches the chat exactly
once, with or without a restart.

## Linked Issues or Issue Description

Refs #20179 (live fix; this PR closes the "Known gap" in its Risks
section).

**What happened**

In an Agent Chat, the agent resubmitted a hire approval and ended its
turn with a yielded result. The finalizer committed
`governed_response_waiting` and moved the task to `in_review`. The
server restarted before run completion posted the reply. Background
presentation recovery found the run as a candidate, but declined it,
because it accepted only `conversation_turn_finished` with a `done`
result. No reply was posted. The run stayed a pending presentation
candidate.

**Expected behavior**

After a restart, recovery posts the held turn's final answer exactly
once. It never posts a second copy when the live path already presented
the answer. When the turn's own question or confirmation card presents
it, recovery posts nothing and records that decision, as the live path
does.

**Steps to reproduce**

1. Open an Agent Chat. Link a pending hire approval to the chat task.
2. Let the agent end the turn with a yielded result and a
`response_wake` continuation. The status decision commits as
`governed_response_waiting`.
3. Stop the server after the status commit and before run completion
presents the reply.
4. Start the server. Presentation recovery runs.
5. See that the chat shows no reply.

## What Changed

- `server/src/services/native-runtime/native-governance.ts`: add
`conversationTurnPresentsAnswer()`. It is the one rule for whether a
successful conversation turn's prose is its answer:
`conversation_turn_finished`, or a committed decision with no pending
card of the turn (`conversationTurnAnswered()`).
- `server/src/services/heartbeat/run-completion.ts`: the live path calls
the shared helper. No change in behavior.
- `server/src/services/native-runtime/native-run-finalizer.ts`
(`recoverCommittedNativeChatResponse`):
- A current conversation turn no longer needs
`conversation_turn_finished`. The turn must still be the unsettled
current turn: same agent, user, session generation, `conversationState:
active`, and no other execution run. A `conversation_turn_finished` turn
still needs `in_progress`.
- A conversation turn with a `yielded` result is accepted next to
`done`.
  - The resolver gets `conversationTurnFinished` from the shared helper.
- When the turn's own card presents it, recovery records
`presentationDecision: none` (reason
`committed_conversation_interaction_presented`) and settles the
conversation turn, like the live path. The run then leaves the pending
presentation set. Before, such a run stayed a candidate.
-
`server/src/services/native-runtime/native-response-presentation-query.ts`:
the candidate prefilter matches the same turns: any committed reason for
an active conversation turn, and `yielded` conversation results.
-
`server/src/services/native-runtime/agent-chat-response-recovery.test.ts`:
restart regressions with the real finalizer and a real database.
- `doc/execution-semantics.md`: state that recovery applies the same
rule.

## Verification

- Failing first. With only the new tests applied, 5 of 7 new cases
failed: pending approval, revision-requested approval, execution stage
(all yielded), pending approval with `done`, and the own-card case. The
run was a candidate, but recovery posted nothing and did not settle it.
- After the fix: `cd server && npx vitest run
src/services/native-runtime/agent-chat-response-recovery.test.ts
src/services/heartbeat/run-completion.test.ts
src/__tests__/idle-native-finalization.test.ts
src/services/presentation-ownership-read.test.ts
src/services/chat-monitor-continuation.test.ts
src/services/native-runtime/native-preserved-monitor-wait.test.ts
src/services/native-runtime/native-response-publication-retry.test.ts
src/services/heartbeat/run-lifecycle.test.ts
src/__tests__/scoped-deadline-work.test.ts
src/services/native-runtime/paperclip-control-plane-port.test.ts
src/__tests__/heartbeat-run-summary.test.ts
src/__tests__/agent-conversations.test.ts`: 12 files, 627 tests passed.
- The new cases check:
- Held turns: the run is a candidate, the check posts the exact final
answer once, the presentation decision is recorded, the run leaves the
candidate set, and a second recovery returns false with one comment.
  - Live already presented: no candidate, no second comment.
- Own question card: no comment, `presentationDecision: none`, the card
stays pending, the conversation settles to `waiting`, and the run leaves
the candidate set.
- Previous-release live decision `none` (`yielded_control_plane_wait`):
kept, not re-presented.
- `tsc --noEmit -p server`: no errors in changed files. Four unrelated
errors remain in this local worktree (`esbuild` not linked in
`native-harness-prestage.test.ts`, and a linked-package type mismatch in
`run-dispatch/adapters/postgres.ts`).
- Turn start: no change. The helper runs only in run completion (after
the provider turn ends) and in background presentation recovery. Nothing
new runs before `turn.start`, and no files move. The live path keeps the
same queries: it short-circuits on `conversation_turn_finished`, and
otherwise runs the same card read as before.

## Risks

- Low to medium. Recovery can now post the answer of a conversation turn
whose task is held. This matches the live path since #20179.
- A card-presented turn found by recovery is now settled with
`presentationDecision: none`. Before, it stayed a pending candidate and
kept the presentation worker (and idle-sleep checks) busy.
- A `conversation_turn_finished` turn keeps the `in_progress` check.
Held turns accept any status their gate committed. The unsettled-turn
checks (active conversation state, session generation, execution run)
still block stale or superseded turns.
- Previous-release state: no persisted shape changes. A run committed by
the previous release with no saved presentation decision (the restart
window) is recovered by the new code. The test fixture uses the
unchanged finalizer, so it saves exactly the previous release's shape. A
run whose live path already recorded a decision keeps it. A held turn
that the previous release recorded as `yielded_control_plane_wait` is
not re-presented, so no late duplicate or stale reply appears.
- Not changed: generic stranded-work recovery in `recovery/service.ts`
still skips only `conversation_turn_finished` runs during the
publication window.

Devin FoleyandPaperclip 9b71d03215 fix: recover interrupted native preparations and unblock upgrades (#20177)
## Thinking Path

> - Paperclip manages AI-agent companies and their work.
> - A native run prepares its workspace before a runner PID or
checkpoint exists.
> - A server crash can interrupt that stage and leave its controller on
another host.
> - Recovery needs a durable owner proof, a delivered recovery wake, and
the saved execution contract.
> - The old paths missed controller lease registration and boot proof,
skipped checkpoint-free preparations, and counted retained work as live
upgrade blockers.
> - This PR connects preparation to the existing controller lease and
recovery paths, and separates retained work from the upgrade census.
> - The result is bounded recovery without a second executor or loss of
saved work.

## Linked Issues or Issue Description

**What happened?**

A native preparation interrupted by a server crash could remain running
indefinitely with no runner PID or checkpoint. Native controller stamps
did not wake the shared instance lease. That lease was disabled on
volume-backed Railway services, and native takeover omitted the boot
binding needed for its cross-host proof. Scoped recovery selected
checkpoint-backed runs but skipped these preparations. The upgrade probe
then counted the retained row as current execution and could block every
later upgrade.

**Expected behavior**

Track the preparation's controller before a runner starts. Recover it
through the normal classifier after proving its owner stopped or fencing
that boot. Keep live or unprovable owners held. Deliver recovery wakes
to preparations without checkpoints. Preserve unresolved historical work
and report it separately from current execution during upgrade
observations.

**Steps to reproduce**

1. Save an observed native preparation with no runner process, result,
provider-start evidence or checkpoint.
2. Replace its controller with a process in another PID space. Let its
owner lease expire and send a scoped recovery wake.
3. Before this fix, recovery skips the checkpoint-free preparation or
cannot prove its foreign controller stopped. Upgrade readiness continues
to count that old row as a live blocker.

Related work: #18037, #19651, #19868, and #20168. The foreign-PID guard
from #19868 remains. The queued first-turn input fix from #20168 is
included through the current base.

## What Changed

- Register the existing instance lease when native execution and restart
claims are written. Keep passive identity reads free of ownership
effects. Keep that lease enabled on volume-backed Railway services
unless explicitly disabled.
- Preserve the existing PID/start-time proof within the same readable
PID space. Bind foreign or unknown-space takeover to its saved boot and
last write. A live lease or grace period keeps the run held with a
scheduled check. Repeated evidence waits preserve their timestamp.
- Include explicitly fenced, checkpoint-free preparations in the
existing finite recovery candidate inventory. Normal launch, checkpoint,
provider evidence and admission checks still decide whether work may
resume.
- Expose the existing board stop-confirmation operation for historical
foreign-host owners. Bind confirmation to the exact run, boot, PID,
process start and host. Reject changed ownership.
- Report narrowly defined old, unowned preparations as
`retainedBlockedRuns` outside the live upgrade census. Local executions,
pending admission, drain state, truncation and positive checkpoint proof
retain their barriers.
- Update the execution contract and add PostgreSQL, real-route, race and
preservation regressions.

## Verification

- Genuine red/green regressions cover the old upgrade census, missing
native lease registration, the volume-backed default, foreign-host
confirmation, and scoped recovery skipping checkpoint-free preparation.
Test bodies ran against real PostgreSQL before their corresponding
production changes.
- Combined verification before the final idle correction (head
`055be6c84d9`): **459 passed, 22 skipped, 11 files passed**. Covers
controller lease/identity, native restart classification and
integration, host confirmation, heartbeat recovery, instance route
authorization, upgrade readiness, and queued first-turn input. The
focused command used `pnpm exec vitest run` with those 11 suites and
`--maxWorkers=1 --no-file-parallelism`. The 22 skipped cases require the
Rust debug fake-Codex fixture, which was not built locally; the
real-process CI coverage must pass.
- `pnpm --filter @paperclipai/server typecheck`: passed on head
`055be6c84d9b058064daad0af71bb5d893ab9529`.
- Actual route proof uses the real heartbeat service and PostgreSQL.
Unauthorized access returns 403. The retained run and owner records
remain unchanged. Recovery integration admits one bootstrap claim across
two replacement controllers, keeps a live owner held, and preserves
local execution.
- `pnpm verify`: exit 2, requests broad CI because the execution
contract changed. Full local suite not run. Current-head CI must supply
broad coverage.
- Local source checkout on macOS ARM64, Node v25.6.1, pnpm 9.15.4. Tests
use isolated PostgreSQL. No live provider restart is claimed by those
fixtures.
- CI found an idle-query regression in the first version of the lease
wiring. Two focused PostgreSQL regressions reproduced the misplaced
identity-read notification and the missing claim notification. The fix
moves registration to actual ownership writes. `env -u npm_execpath pnpm
exec vitest run server/src/__tests__/maintenance-server-routes.test.ts
--maxWorkers=1 --no-file-parallelism`: **17 passed**, including 90 real
seconds and two qualified hourly windows with no extra idle queries. An
initial local setup attempt inherited npm metadata and did not run
tests; clearing that metadata selected the correct pnpm helper. Three
focused controller/native suites also passed **168 tests, 22
fixture-gated skips**. Server typecheck passed after the correction on
head `4a527326dcd5b3a9e286f0e4c3e761d3056af4d9`.
- The older CI server shard also exposed a same-space graceful-restart
regression. The new boot fallback had overridden local process-exit
proof. Seven suspension cases and a focused unit regression reproduced
it; the fix limits boot fallback to foreign or unknown PID spaces. Fresh
verification on `acf1065d98150210c1e227c7f3b05a1eb489730b`: **251
passed, 22 fixture-gated skips, 4 files passed**, including all **40**
graceful-restart suspension tests. Server typecheck passed. The local
regression failed before this correction, and the same-space and
foreign-space paths pass together after it.
- Current-head CI completed successfully on
`acf1065d98150210c1e227c7f3b05a1eb489730b` (run 42568109784). Greptile
reviewed that exact head at 5/5 with no unresolved review threads.
- Secret and private-data scans passed. No workflow, lockfile or
migration changes.

## Risks

- The instance lease now applies to volume-backed Railway services. Its
existing 30-second renewal, quiescence, grace and self-fence behavior
applies while work is held. Idle servers retain the existing no-query
behavior. An explicit `PAPERCLIP_CONTROLLER_INSTANCE_LEASE=off` remains
available.
- A controller lease proves only the server owner's state. It does not
prove an agent process stopped or authorize replay, resource release or
volume removal. The existing classifier and provider/runner checks
remain responsible for those decisions.
- Previous-release records keep their shape and saved state. A missing
boot lease stays unprovable and requires the scoped stop-confirmation
path. A changed confirmation target is rejected.
- The upgrade observation does not recover a held task by itself. Source
tests do not qualify a hosted replacement. Deployment and the affected
task's useful result must be verified separately.
- This repairs recovery after a crash; it does not claim to identify or
fix every source of heap exhaustion.

DottaandClaude Opus 5.5 95bf90bd2c fix(chat): post a conversation turn's answer while an approval holds the task (#20179)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - People talk to agents in chat. The agent's final message becomes the
chat reply.
> - A chat turn can end while the task stays held. For example, the
agent resubmits a hire approval and the approval is pending.
> - The finalizer keeps the task in review for the approval
(`governed_response_waiting`). That decision is not
`conversation_turn_finished`.
> - Run completion then treats the yielded turn as a control-plane wait.
It records `presentationDecision: none` and posts no comment.
> - The person never sees the agent's answer. The chat shows nothing
after the request.
> - This pull request counts a committed conversation turn as answered
unless its own pending question or confirmation card presents it.
> - The benefit is that the person always gets the reply, whatever state
the task keeps.

## Linked Issues or Issue Description

Refs #19971 (post the full final reply). That fix covers the reply text.
This fix covers replies that were never posted.

**What happened**

In a chat, the person asked the CEO agent to change a proposed hire to a
cheaper model and send it back for approval. The agent resubmitted the
approval correctly. It called `paperclip_finish`, and Paperclip accepted
the report with "task is still waiting for approval". The run succeeded
and the task moved to `in_review`. The run event
`run.presentation.resolved` recorded `commentAction: none` (reason
`yielded_control_plane_wait` on master). The agent's final message never
reached the chat.

**Expected behavior**

A chat turn's accepted final answer is always posted to the
conversation. An approval, an execution stage or a dependency blocker
can hold the task. It must not hide the reply. Only a question or
confirmation card that the turn itself left pending presents the turn
instead of its prose.

**Steps to reproduce**

1. Open an Agent Chat with an agent. Link a hire approval in
`revision_requested` to the chat task.
2. Ask the agent to change the hire and resubmit it.
3. The agent resubmits the approval and ends the turn with a yielded
result and a response wake.
4. See that the chat shows no reply. The run is `succeeded` and its
presentation decision is `none`.

## What Changed

- `server/src/services/native-runtime/native-governance.ts`: move the
pending-card query of `pendingNativeGovernance()` into
`pendingNativeInteraction()`, with no change in behavior. Add
`conversationTurnAnswered()`. It returns false only when a pending
thread interaction (the same predicate as status arbitration) gates the
turn. It checks cards on their own, so a pending execution stage does
not hide a card.
- `server/src/services/heartbeat/run-completion.ts`: a successful
conversation run whose status decision committed now passes
`conversationTurnFinished: true` to the presentation resolver, unless
`conversationTurnAnswered()` is false. The existing
`conversation_turn_finished` path is unchanged.
- `server/src/services/heartbeat/run-completion.test.ts`: add a
regression table with a real database. A pending approval, a
revision-requested approval, a pending execution stage and a dependency
blocker now post the answer. A finished turn still posts. The turn's own
question card still owns the response, also when an execution stage is
pending.
- `doc/execution-semantics.md`: state the rule.

Other finish outcomes I checked:

- `done` or `needs_review` with a gate (`governed_gate_pending`): the
result is not yielded, so the reply was already posted.
- `blocked` (`paperclip_block`, waiting on a person or another task):
not yielded, so the reply was already posted.
- Yielded with a dependency blocker
(`durable_dependency_blocker_bound`), or with
`record_finalization_error` (`prior_status_preserved_no_live_path`,
`monitor_wait_authority_lost`): the reply was also dropped. This fix
covers them, because the rule does not depend on the reason code.

## Verification

- `cd server && npx vitest run
src/services/heartbeat/run-completion.test.ts`: 118 passed. Before the
fix, 4 new cases failed (both approval states, execution stage,
dependency blocker). The finished-turn and question-card cases passed
both before and after.
- `cd server && npx vitest run
src/__tests__/heartbeat-run-summary.test.ts
src/services/heartbeat/run-comment-selection.test.ts
src/__tests__/slack-conversation-lifecycle.test.ts
src/services/native-runtime/agent-chat-response-recovery.test.ts
src/__tests__/chat-run-milestone-governed-work.test.ts
src/__tests__/agent-conversations.test.ts`: all passed.
- `tsc --noEmit -p server`: no errors in the changed files. Unrelated
errors in this worktree come from an unbuilt local Runner package.
- An end-to-end chat eval run on the case branch is in progress. I will
add its result here.

## Risks

- Low risk. The change only affects successful Agent Chat runs with a
committed status decision. Ordinary tasks and external chat (Slack,
GitHub) keep their own paths. External chat returns before this check.
- A turn that yields while an approval is pending now posts its prose.
The approval stays pending and the task status does not change.
- One extra small read (the task row and pending gates) runs after a
conversation turn that is not `conversation_turn_finished`. It runs
after the provider turn ends, so it does not add time before the first
token.
- Previous-release state: no persisted shape changes. The fix reads
`finalizationPhase` and `finalizationReasonCode`, which the previous
release already writes. A run in flight at the deploy completes on the
new code and posts its reply. A run that completed before the deploy
keeps its recorded decision; nothing re-presents it.
- Known gap, unchanged: background presentation recovery for
conversations still requires `conversation_turn_finished` with a `done`
result. If the server restarts between the status commit and the live
presentation, a held yielded turn is not re-posted. That is a separate
follow-up.

DottaandClaude Opus 5.5 5a51a7685d fix(budgets): raise_budget_and_resume continues the work its budget stopped, once (#20144)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A budget hard stop cancels the scope's running work; the board
resolves it with Raise budget and resume
> - In the restart-chaos H1 scenario, the cancelled tasks did not
continue after resume and each needed a manual Retry
> - Resume is the board's explicit decision to continue, so the work it
stopped should continue once, as if the board clicked Retry
> - This pull request files that Retry automatically, keyed by the
cancelled run, once the run's stop has settled
> - The benefit is that a budget raise restores the work without manual
Retries, without repeating completed work, and without charging the
run's attempt budget

## Linked Issues or Issue Description

Refs #20143 (bug B; this PR builds on it), #20113 (bug A), #20101
(superseded: split into #20143 and this PR)

**What happened?**
Restart-chaos waves w-20261108T195944-s42 and w-20261108T210118-s9802
(H1). After `raise_budget_and_resume`, CHA-3's budget-cancelled run
(enforcement stop) and CHA-1's run (agent lifecycle pause from the
budget hold) stayed cancelled until someone clicked Retry.

**Expected behavior**
Resuming continues each task its budget stopped, exactly once, with no
attempt charged, an activity entry, and no repeat of work that already
continued. A run a person stopped stays stopped.

**Steps to reproduce**
Set a budget below spend while a task runs; let the stop cancel the run;
resolve with Raise budget and resume. Before this change, no new run is
queued.

## What Changed

- New table `budget_resume_claims` (migration 0451). One row per
cancelled run, outside the run's result JSON, so a Stop that settles
during the resume cannot erase it.
- `markBudgetCancelledWorkForResume` (called by `resolveIncident` before
the incident closes): claims every task run its budget stopped since the
incident opened. That covers runs budget enforcement fenced, including
stops still in flight, and runs the agent lifecycle pause stopped for
this budget (`pauseStop`, carried from the lifecycle operation's
`pauseCause` so a resume before the Stop keeps the link). Runs a person
stopped are excluded. Two indexed passes led by `(company_id, status)`.
- `deliverBudgetResumeContinuations`: once a claimed run's stop settles,
files the resolving board member's Retry (`requestTaskRetry`,
idempotency key `budget-resume:<run>`, with the member's session source
and the chat Retry callback). The Retry path checks, under the task
lock, that the run is still the task's latest and the task is open, so
continued or completed work is never repeated. Claim settlement and its
activity entry commit together; retryable refusals and errors retry.
- Delivery runs in the always-on budget-enforcement worker after each
pass's Stop delivery. Its schedule includes deliverable claims and the
earliest stale-claim expiry. The execution-continuation worker is a
backstop.
- `agent.paused` / `agent.resumed` logging is in #20113.
`budget.cancelled_work_resume_requested` (incident) and
`budget.cancelled_work_continued` / `_not_continued` (task) are recorded
here.

## Verification

- New `budget-resume-continuation.test.ts` (Postgres, real
`resolveIncident` → claims → `requestTaskRetry` → real `resumeTaskRetry`
into a queued run):
- each task continues once, including a blocked task; repeat delivery or
resolve saves nothing new;
- a stop still in flight at resume, whose terminal write replaces the
result JSON, is still continued;
  - a 30-task scope is fully continued;
- a lifecycle-pause stop caused by the budget is continued, and one
caused by a manual pause is not;
- continued work, done tasks, a run that finished before its stop, and
person-stopped runs (including ones enforcement also fenced) are not
continued.
- `lifecycle.test.ts`: the pause records its cause on the operation and
on stopped runs, including when the budget is resumed before the pause's
Stop. `budget-enforcement-worker.test.ts`: delivery after Stop delivery,
and a wake at claim expiry.
- 287 tests across the affected suites passed. Server typecheck
(`typecheck-layers`, low-memory): no errors.
- Not run: the H1 chaos rerun (Phase 3 runs it after merge).

## Risks

- Resume now continues budget-stopped tasks automatically. A board that
wants a task stopped can Stop it again; person-stopped runs are never
continued.
- A new table and one index (migration 0451).

DottaandClaude Opus 5.5 b54317d3fb fix(native): give a preparing run's first turn the user's queued messages instead of interrupting it (#20168)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A Paperclip Runner (native) run prepares its workspace and
environment before it starts its first provider turn. This can take
about a minute.
> - A user's message that arrives during that time waits as a deferred
wake behind the run. The Interrupt control then cancelled the run before
any provider turn.
> - The cancel threw away the whole preparation. A new run had to
prepare again, so the user waited longer for the first token.
> - This pull request gives the run's first turn the queued messages.
The run seals its first-turn input immediately before `turn.start`, so
the messages are part of the prompt that the turn starts with.
> - The benefit is that the user sees the message handled in the same
run, with no cancel and no second preparation.

## Linked Issues or Issue Description

**What happened?**
A Paperclip Runner run took about 54 s to prepare (environment startup,
workspace, runtime selection). The user sent a second message 32 s into
that time and clicked Interrupt 21 s later. Interrupt cancelled the run
as `operator_interrupted` ("Interrupted to send queued messages") before
any provider turn. A new run then prepared again from the start. The
runtime-selection transaction that froze the run's input completed about
5 s before the click, and the coordinator claim came 4 s after it, so
the message could not be given to the first turn at any point in the old
code.

**Expected behavior**
When a user message arrives for a task whose current run has not started
its first provider turn, the run does not stop. The message goes into
that run's first turn. A run that is in a turn is interrupted as before.

**Steps to reproduce**
1. Assign a task to a Paperclip Runner agent with a sandbox environment,
so preparation takes a long time.
2. While the run prepares, post a second comment on the task.
3. Click Interrupt on the queued message before the run starts its
provider turn.
4. See that the run is cancelled and a new run prepares again.

**Paperclip version or commit**
Staging revision b43cccbb0.

## What Changed

- `server/src/services/native-runtime/first-turn-queued-input.ts` (new):
`claimFirstTurnQueuedInput` seals a run's first-turn input in one
transaction. It locks the task, the deferred wakes, and the run in the
same order as the queue routes. It takes the responsible user's plain
queued comments in queue order (not interaction answers, interrupt
intents, independent continuations, conversations, or other users'
messages). It renders them with source-trust sanitizing and secret
redaction, then writes a `firstTurnQueuedInput` receipt
(`paperclip.first-turn-queued-input.v1`) into the run context. A second
call for the same run returns the same messages.
`runAcceptsFirstTurnQueuedInput` is true for a running native (or
preparing native) run that has no receipt and no accepted provider turn.
- `packages/paperclip-runner/src/native-session-runtime.ts`: new
`getFirstTurnQueuedInput` option. The runner calls it immediately before
the first `session.startTurn` and appends the result to `task.prompt`
(or to `events` for a resumed-session continuation envelope). It is not
called for the disposition-only recovery turn.
- `native-session-executor.ts`: passes the claim to the runner. A failed
seal commits nothing, so the executor logs it and starts the turn
without the messages. The messages stay queued.
- `queued-comment-delivery.ts`: a message in a run's receipt counts as
delivered only after the provider accepted that run's turn
(`turn.accepted` or the provider's `turn.started`), and only if the
message was not edited after the seal. Release promotion, Send, and
later first turns use this rule. `explicit-native-continuation.ts` uses
the same rule for stopped native runs.
- `routes/issues.ts` Interrupt: when the target run has not sealed its
first turn and has no accepted turn, the route does not record interrupt
intent and does not cancel the run. The response has
`executionWait.reason = "first_turn_pending"`. Other runs are
interrupted as before.
- Queue views (`routes/issues.ts` and the wake-queue adapter) hide
messages that the active run took into its first turn. Queue edits keep
those ids on the wake, so a run that fails before acceptance still
leaves them queued.
- `run-state.ts`: the issue-control run projection includes the receipt,
so the queue poll can hide taken messages.
- `doc/execution-semantics.md`: new section "Queued messages before a
native run's first turn".

## Verification

- Red before the fix, green after:
- `pnpm --filter @paperclipai/server exec vitest run
src/__tests__/issue-queued-comments-routes.test.ts -t "first
turn|already started"`: Interrupt on a preparing run and on a claimed
native run before `turn.start` does not stop the run, and the first turn
gets both messages in order. Before the fix, both cases cancelled the
run.
- `pnpm --filter @paperclipai/paperclip-runner exec vitest run
src/native-session-runtime.test.ts -t "first-turn queued input"`: the
claim runs immediately before `turn.start`, and the first turn's prompt
ends with the queued messages. Before the fix, the claim was never
called.
- `pnpm --filter @paperclipai/server exec vitest run
src/services/native-runtime/first-turn-queued-input.test.ts`: a run that
fails before `turn.start` leaves the message queued. The next run
delivers it, and after that no later run or copied retry context takes
it again. Before the delivery rule, the "exactly once" and "accepted
then failed" cases failed.
- Safety cases that pass before and after: Interrupt still cancels a run
whose provider accepted a turn (including a run saved by the previous
release with no receipt) and a run whose first-turn input is already
sealed. The existing "explicit interrupt fallback" cases for preparing
and native runs without a responsible user still pass.
- Speed: the seal is one short transaction before `turn.start`. In the
embedded-Postgres test it took 5.5 ms. It removes a full second
preparation (54 s on staging) from the message-to-first-token time.
- Related suites: `src/modules/wake-queue`,
`explicit-native-continuation`, `issue-queued-comment-queue`,
`issue-queued-comments-routes`, `queued-comment-consumption`,
`heartbeat/run-state` (888 tests), `native-session-executor.test.ts`
(1306 tests), and the full `native-session-runtime.test.ts` (238 tests)
pass. `pnpm --filter @paperclipai/server typecheck` passes.
- Not done: no live run against a real provider or sandbox. Staging was
read only.

## Risks

- Previous-release state: a deferred wake saved by the previous release
has the same shape and is taken normally. A run saved by the previous
release has no receipt. If it is resumed before its first turn, it seals
on the new release. If its provider already accepted a turn, Interrupt
stops it as before. A run saved by the previous release while it was in
`turn.start` but before acceptance counts as unsealed, so in that short
window an Interrupt does not stop it and the message is delivered at the
turn boundary.
- Rollback: if the server rolls back after a run sealed and its turn was
accepted, the old release does not read the receipt and can deliver
those messages a second time.
- A first turn that does not use the fresh-turn path (restart
continuation, disposition-only recovery) does not call the claim. Its
messages are delivered at the turn boundary as before.
- A message that arrives after the seal waits for the turn boundary.
Interrupt stops the run as before.
- No schema migration. The receipt is a key in the run context.

DottaandClaude Opus 5.5 098f7d370b fix(workspaces): release an unchanged remote writer without a snapshot and wake its waiters (#20171)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A remote (sandbox) task workspace has one writer run at a time. The
writer holds the workspace until its files are saved as a snapshot
> - A run that a user comment interrupts right after its claim did no
work. No provider turn started and no command ran in the sandbox
> - Paperclip still kept its sandbox, then took a full snapshot of the
unchanged workspace. On a 2 GB repository this took 3 minutes
> - The next runs failed setup with `workspace_busy` ("ended, but its
workspace save has not settled"). The retry then waited for the
one-minute settling re-check after the save. The user's message waited
more than 4 minutes
> - This pull request releases such a writer at once, at the saved
version it started from, when durable evidence proves that it changed
nothing. It also wakes parked `workspace_busy` waiters when a hold
settles
> - The benefit is that an interrupted run no longer delays the next
message by a full workspace save

## Linked Issues or Issue Description

**What happened?**
A remote-workspace run was claimed (`native.coordinator.claim`). One
second later a board comment interrupted it (`operator_interrupted`). It
made no provider turn and no tool calls. Cancelled-workspace
preservation still retained its sandbox, and workspace recovery took a
full `remote_workspace_snapshot` of the unchanged workspace (3 minutes
for a 2 GB repository). Two follow-up runs were cancelled with
`workspace_busy`. Their retry was due during the save, and it parked for
the one-minute settling re-check after the save finished.

**Expected behavior**
A writer that provably changed nothing releases the workspace at once
and keeps its existing `snapshotId`. The next run is admitted without
`workspace_busy`. When a save does run, waiters start as soon as it
commits.

**Steps to reproduce**
1. Run a task on a remote sandbox workspace that already has a saved
version.
2. Interrupt the run with a board comment right after the claim, before
the provider turn.
3. See the full snapshot operation on the interrupted run and
`workspace_busy` on the follow-up runs.

**Paperclip version or commit**
Staging served revision b43cccbb0. Reproduced on `master` by the new
regression tests.

## What Changed

- `prepareRemoteWorkspace` records `remoteWorkspaceUnchangedBaseline`
(epoch, writer run, saved version) when preparation started from a clean
saved version and added nothing to it: no recovered attachments, no
repository outside the saved version and no workspace migration.
- New `proveRemoteWorkspaceUnchanged`
(`remote-workspace-unchanged-proof.ts`). It uses only durable evidence.
The writer run must have ended without a result, and its owner fence
must be clear. It must have no process fields, no execution, provider or
tool events (the shared `executionStartedEventPredicate`), no native
result, no runner checkpoint rows (the controller writes one before
every runner command), and no provider turn in a checkpoint that names
this run. It must have no workspace operation other than a restore or a
`workspace_finalize`/`workspace_recovery` receipt, so provisioning and
saves count as writes. Every task repository must be in the saved
version. Any missing or ambiguous evidence refuses.
- New `releaseUnchangedRemoteWorkspaceWriter`. It sets the authority to
clean with no writer, keeps `snapshotId`, marks the run reference
`saved`, logs `workspace.snapshot_skipped_unchanged` and sends the same
notifications as a final save. It never waits on a writer run that
another transaction holds (`skip locked`).
- The release applies in three places: the next run's
`reserveRemoteWorkspace`, cancelled/failed-workspace preservation
(`preserveNativeFailedWorkspace`), and `saveRemoteWorkspace` with the
final boundary. The final save returns the same version on a repeated
call, so a recovery that raced the release finishes without a capture.
- The final-save commit and the unchanged release call
`wakeWorkspaceBusyWaitersInTx`. A parked waiter whose holder was that
writer is due at once, not at the one-minute settling re-check.
- `doc/execution-semantics.md` describes the release and the wake.

## Verification

- `pnpm --filter @paperclipai/server exec vitest run
src/services/remote-workspace-unchanged-release.test.ts` (13 tests,
embedded Postgres, real archive capture):
- Staging shape (claim, then interrupt with no provider work): the next
reservation is admitted. No snapshot operation is recorded. The run
reference is `saved` at the old `snapshotId`. Red on `master`: "The
workspace still has an unfinished writer or save operation."
- A later final save, behind the `workspace_finalize` receipt that
production finalizers publish first, returns the same version with no
capture, a repeat returns it again, and a parked waiter becomes due now.
Red on `master`: a new snapshot is captured.
- Negatives that still do a full save: `turn.started`, `provider.event`,
`tool.execution.started`, `native.process_start_requested`, a
provisioning command that wrote into the workspace, a recorded process,
a live owner fence, and a writer that is still running.
- Upgrade safety: no baseline (a writer prepared by the previous
release), a baseline without its saved version, and a baseline with
another schema each keep the full save.
  - A full final save wakes the parked waiter. Red on `master`.
- `native-cancelled-workspace-preservation.test.ts`: a new case shows
that a cancelled writer with a baseline and no work is released, with no
retained lease and no recovery action. Red on `master` (the
restore-recovery hold was recorded). The other 44 cases pass unchanged.
- I also ran the related remote-workspace, workspace-recovery, native
preservation and run-dispatch suites locally.

## Risks

- A false "unchanged" verdict would drop unsaved files. The proof
requires a positive baseline from preparation and refuses on any write
record. Only `.paperclip-runtime` (excluded from snapshots) is written
by runner staging before a process starts. A deploy that lands mid-run
keeps the full save, because the proof reads only durable rows.
- Previous-release state: a writer prepared without the baseline (or
with an unknown or partial one) keeps today's full save. An older server
ignores the new metadata key.
- Waiters now start sooner after a final save. Arrival order among
waiters is unchanged (the park check still admits the earliest first).
- Other ways a hold can settle (for example a stop receipt that turns an
unused reservation free) still rely on the one-minute re-check.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, used in Claude Code
with tool use (shell, file edits and a read-only browser for staging
evidence).

DottaandClaude Opus 5.5 4f7eee10c2 feat(recovery): let the board confirm an unrecorded owner stopped for every settling process kind (#20084)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Recovery releases in-progress records (leases, claims, intents) only
when it can prove their owner is gone
> - A record saved before its server process was fully recorded is
`unprovable`, and it is never released on its own
> - #20067 added a board-only action to confirm that such an owner
stopped, but only the environment run lease used it
> - Other settling kinds (for example the legacy controller lease, which
shows `missing_identity` rows in the Phase 2 reconciler data) stay stuck
with no way forward
> - This pull request opens the same confirmation to every settling kind
whose record names a partly recorded server process
> - The benefit is that an operator can release these stuck records
safely, and recovery settles them at once

## Linked Issues or Issue Description

Refs #20067, #20054

**What happened?**
The Phase 2 reconciler data shows `legacy_controller_lease` records that
stay `unprovable` with `missing_identity`: they were saved before
Paperclip stored the controller's PID space. Recovery never releases an
unprovable owner, and only the environment run lease offered the board's
"confirm the previous server stopped" action. These records, and records
of other settling kinds saved the same way, had no path forward.

Also, a board confirmation did not wake the reconciler. Unprovable
records are not watched, so the release waited for some unrelated pass.

**Expected behavior**
Recovery asks the board on the record's task. After the board confirms,
recovery releases the record through the kind's own compare-and-swap
settle, at once. A confirmation never releases a record that changed
since the board was asked.

**Steps to reproduce**
1. Have a legacy run whose `controller_process` was recorded without a
host hash (an older server).
2. Run the ownership reconciliation pass. The record is `unprovable`
(`missing_identity`) and no board action appears.

**Paperclip version or commit**
master at c55af26821.

## What Changed

- `ownership-registry.ts`: a new `ownerGoneAttestable` helper opts a
settling kind in. The kind asks the board (cause
`ownership_owner_unprovable`) only for a process-owned record that is
unprovable for a legacy reason and has a version. Opted in:
`legacy_controller_lease`, `environment_teardown_claim`,
`sandbox_creation_intent`, `workspace_runtime_control_operation`,
`native_workspace_finalize_attempt`, `native_finalizer_lease`,
`native_cleanup_lease`.
- `owner-gone-attestation.ts`:
- The request records the record version (`recordUpdatedAt`), and each
pass refreshes an open request to the current version.
- The board submits the version it was shown (`recordVersion`, a new
optional field in `confirmOwnerGoneSchema`). The confirmation is refused
with 409 unless that equals the request's current version and the locked
record's version.
- `recordVersionAttestations` reads back every resolved confirmation.
Any one that names the record's current version applies.
- `confirmOwnerGone` now wakes the ownership reconciler in its
transaction.
- Each opted-in kind has a version lock. For an `operator_attested`
proof, its settle runs in a transaction that locks the record row and
re-checks the confirmed version before the kind's own compare-and-swap.
- `ownership-invariant-report.ts`: in the periodic pass and in one-shot
settles, a matching confirmation turns a legacy `unprovable` verdict
into `gone` (`operator_attested`). A live or provable owner always wins.
The extra read runs only when a kind has such a record.
- `WorkspaceExportRecovery.tsx`: the board's confirmation names the
stuck record by kind (for example "This task's earlier run"), with a
generic fallback, and sends the version it showed.
- `doc/execution-semantics.md`:
- It describes the action, the version binding and which kinds are
offered.
- It updates the controller-lease section to match #20054: the holdings
list, and that the lease is off only on Railway deployments with an
exclusive volume.

## Verification

- `pnpm exec vitest run src/__tests__/owner-gone-attestation.test.ts`
(server): 10/10. The new legacy-controller cases fail without the
change:
  - the board is asked, and nothing is released before the confirmation;
- the confirmation wakes the reconciler, and the next pass settles the
record as `operator_attested`;
- a record that changed after the confirmation is not released, and a
fresh request is raised;
- a record of these kinds with no owner stamp is not offered, because
its settle could never release it;
- a confirmation for a version the record no longer has is refused, and
the refreshed request then applies;
- a write between the reconciler's listing and its settle stops the
release inside the settle's transaction.
- The 10 server ownership suites (registry, report, owner proof,
controller lease, legacy controller, teardown, finalize, token leases):
332/332.
- `pnpm exec vitest run
src/components/WorkspaceExportRecovery.control.test.tsx` (ui): 48/48.
- `pnpm check:token-gates`: all gates clean.
- `PAPERCLIP_TYPECHECK_LOW_MEMORY=1 pnpm typecheck` in `server` and
`ui`: passed.

## Risks

- A wrong release would be serious. The safeguards:
- The confirmation applies only while the record's last-write time
equals the one the board was asked about, and only while the prover
still finds the recorded process unprovable for a legacy reason.
- Each kind's settle still compare-and-swaps on the exact recorded
process.
- A record of these kinds with no owner stamp at all is not offered.
Those settles cannot release it, so it keeps its existing recovery path.
- Kinds that are unowned by design (queued pending cleanup, accounting
debt) are not offered.

DottaandClaude Opus 5.5 e8a3f1f6f2 feat(recovery): prove a replaced container's records gone through a fenced controller epoch (#20054)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - After a restart, the control plane settles in-progress records
(leases, claims, intents) only once it proves their owner process is
gone
> - The proof compares host and PID space, so a stamp from a replaced
container or a rebooted machine stays unprovable forever, and its
records never settle
> - Self-hosted users on Docker, Kubernetes and Fly hit this on every
redeploy; a Railway deployment with an exclusive volume is covered by
`deployment_replaced` (#20026)
> - This pull request adds a fenced controller epoch: each boot holds a
database lease, and an expired boot is fenced so its records can be
proven gone
> - The benefit is that work stranded by a replaced container is
recovered, without keeping an idle database awake

## Linked Issues or Issue Description

Follow-up to #20026 and the Phase 2 durable-ownership data. Related:
#19965 (owner stamps), #19883 (process space). No duplicate PR was
found.

**What happened?**

A record stamped by a server process in another container reports
`different_process_space`. A dead PID elsewhere is never proof, so the
record stays `unprovable` and is never settled. Every redeploy of a
self-hosted container leaves such records behind.

**Expected behavior**

A record owned by a server boot that was replaced (stopped cleanly, or
lost its lease and was fenced) is proven gone and settled exactly once.
A live boot's records stay with it. An idle server issues no recurring
queries.

**Steps to reproduce**

1. Run Paperclip in a container and start work, so an environment lease
is stamped by that boot.
2. Replace the container. The new container has a new PID namespace.
3. The ownership reconciler reports `different_process_space`
(unprovable) for the old lease, forever.

**Paperclip version or commit**

`master` before this PR.

## What Changed

- New `controller_instances` table (migration 0449): boot id, epoch
(bigserial), process space, pid, a lease on the database clock,
`fenced_at` / `fenced_by_epoch`, `stopped_at`.
- `controller-instance-lease.ts`, registered with the shared
delivery-work coordinator (`controller-instance-lease` queue, runs
during drain):
- **Holds work → renews; idle → silent.** One upsert creates the row on
first use and extends the lease only if the boot holds work: a stamp
within the last 90 s, or a stamp whose ownership write may still be
pending (held until the server's tracked work settles, capped at 10
minutes; a renewal that sees some other held record does not clear it,
so a slow ownership write cannot be outlived), or an in-progress record
held by its boot id. Those records are active environment leases,
in-flight cleanup claims, sandbox creation intents, workspace finalize
attempts, agent lifecycle steps, native finalizer and cleanup leases
(`lease_holder` bound to the token), open native coordinator claims, and
running legacy runs. Renewal runs every 30 s while the boot holds work.
When it finds none, the lease lapses and the worker sleeps until the
next stamp (`onControllerStamp`).
- **No idle trailing statements.** When the server's last tracked work
settles, the worker re-checks holdings at once, at most every 5 s (the
rate limit also absorbs the worker's own run). So the last check happens
with the work, not 30 s later.
- **Quiesce, don't crash.** Each renewal has a 10 s bound. A failed or
timed-out renewal applies an internal task drain, so no new work is
dispatched. A recovered renewal resumes. The boot exits only after 60 s
of failure (counted from the first failed attempt's start) while it
still holds work, or at once when it finds itself fenced.
- **Fence on demand, by a newer epoch.** For a stamp from another host
or PID space, the prover reads that boot's row:
    - `stopped` or `fenced`: gone.
    - live lease: alive.
- otherwise, the boot's last sign of life is the later of its lease
expiry and the record's last write plus the TTL. Within 30 s of that,
the owner stays `alive` (`controller_lease_grace`), so the settle watch
keeps rechecking. After that, the prover fences the boot, but only with
a lease row of its own (created on demand) and only an older epoch.
  - A graceful shutdown records `stopped_at`.
- A reconciliation pass that settles nothing (`record: false` or
`settle: false`) never fences and never creates the boot's row.
- `owner-proof.ts`: these proofs apply only to server-held records. A
stamp with a recorded process group stays unprovable, because agent
processes can outlive their server. The reconciler passes each record's
`updatedAt` to the proof.
- `task-admission.ts`:
- the quiesce drain never replaces an operator's drain, and has no idle
owner, so HTTP stays open;
- a `subscribeIdleWorkSettled` hook fires when the last tracked work
finishes.
- Off on a Railway deployment with an exclusive volume (it has its own
replacement proof). `PAPERCLIP_CONTROLLER_INSTANCE_LEASE=on|off`
overrides this. A stateless Railway service keeps the lease. A server
without its own lease row never fences.
- `maintenance-server-routes.test.ts`: in the post-run quiet window, the
lease may check once more that the run's records were released. The test
now excludes those statements, then asserts that the lease issues
nothing in a further window.
- Docs: `doc/execution-semantics.md`; the Phase 2 data doc records the
two known gaps.

## Verification

- `controller-instance-lease.test.ts` (15 cases):
- a replaced container with all Railway variables empty is fenced and
settled exactly once over two passes;
  - a live lease is alive;
- an owner in grace, and work written after an idle lapse, stay alive
and watched;
  - an older epoch never fences a newer one;
- no fencing without its own lease row (off or unregistered), and an
idle prover creates its row on demand;
  - a stopped boot is gone;
  - process-group stamps stay unprovable;
- idle issues zero statements, and one upsert renews only while records
are held;
  - **a 45 s outage:** quiesced, no exit, resumes;
- **a renewal that never answers:** bounded, and the boot exits on time;
- **a 70 s outage:** exits at 60–65 s, and the successor recovers the
work exactly once;
  - fenced: stops;
  - the settle re-check;
- graceful stop; off on a volume-exclusive Railway deployment, on for a
stateless one, and the on/off override;
  - a running legacy run keeps the lease live.
- Red, with the proof's instance check removed: the replaced-container,
live, stopped and successor cases fail.
- Wider: task-drain, idle-sleep, idle-local-work, owner-proof and
ownership suites, plus the maintenance quiet-window tests. Server
low-memory typecheck is clean.

## Risks

- **Clock skew.** The proof compares a record's `updatedAt` (often the
writer's clock) with the lease (database clock). The 30 s grace absorbs
ordinary skew.
- **A new exit path exists.** A server whose database is unreachable for
more than 60 s while it holds work now exits, after first quiescing.
This is the intended safety backstop.
- **Bounded trailing activity.** A lease that holds work issues one
statement every 30 s, plus at most one check when its work settles. An
idle server issues none.
- **Boots from before this release** have no row, and their records stay
unprovable. The board "mark owner gone" action for those follows in a
separate PR.

DottaandClaude Opus 5.5 d33b3ac263 fix(wake-queue): save temporarily refused work intents and promote them through one path (#19956)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Users send work to agents as assignments, comments and Retries. The
wake queue delivers each one as a run
> - When an admission check refused a wake for a temporary reason, the
wake often ended as a terminal skip, so the work was lost
> - Restart-chaos waves found dropped comments and Retries (RC-37,
s7532) and double delivery (RC-53). Each fix covered one hold type
> - The durable ownership plan (section E) asks for one outbox rule: a
closed set of terminal outcomes, a saved deferral for every temporary
refusal, and one promotion path
> - This pull request adds that rule. It saves messages refused by a
pause, promotes deferred intents from every hold-release event through
one function, and adds a reconciler backstop
> - The benefit is that an accepted message is delivered exactly once
after a pause lifts, and the reconciler reports any intent that is stuck
or dropped

## Linked Issues or Issue Description

Refs #19831 (plan, section E), #19838 (inventory, wake-queue rows and
section 1b), #19927 (Phase 2 data: the I4 false positive), #19702,
#19741, #19829, #19826. Builds on #19944 (section D, merged).

**What happened?**
- A user commented while the agent was paused, or while the company was
paused. Admission refused the wake. Nothing saved the message as
pending, so when the pause lifted, nothing delivered it.
- Hold-release events woke different subsets of workers. A saved intent
then waited out a 30-second refusal backoff after its hold cleared.
- The I4 reconciler check matched free text with a regular expression.
Phase 2 found a false positive: a delivered retry whose error said
"retrying once".

**Expected behavior**
An accepted work intent ends only as delivered, consumed by a later run,
task cancelled, or hard stop. Every temporary refusal saves the intent
as `deferred` with its reason and its release trigger. Every
hold-release event promotes deferred intents through one function
(invariant 4).

**Steps to reproduce**
Pause an agent. Post a user comment on its task. Resume the agent. On
`master` the comment is never delivered as a wake.

## What Changed

- New `server/src/services/work-intent-outbox.ts`:
- `WORK_INTENT_TERMINAL_OUTCOMES`: the closed set of terminal outcomes.
- `TEMPORARY_REFUSAL_TRIGGERS`: maps each temporary refusal code to its
release trigger.
- `promoteDeferredWorkIntents`: the one promotion function. It removes
the 30-second refusal backoff from the matching deferred intents. It
then wakes run dispatch, the saved-receipt worker and stranded-work
recovery, and hints each saved intent of the issue.
- `heartbeat/queue.ts`: the #19829 save-as-deferred block is now a
shared helper. A user's message refused by a paused agent, a paused
company, or a budget pause that is not a reached hard stop is saved with
`executionWait: { reason, trigger, message }`. The caller still gets a
409. The message is saved only when the task's latest run is terminal,
because the release drain promotes a saved message behind that run. A
task that never ran keeps the message in the task, and stranded-work
recovery starts the task once the pause lifts. A `pending_approval`
agent and a task-tree hold are not changed here: the release drain still
fails a promoted wake for a pending approval, and tree holds have their
own resume path.
- Hold-release events call `promoteDeferredWorkIntents`:
  - accounting settled (`run-cost-accounting.ts`);
  - environment lease released (`environments.ts`, two sites);
  - native run projected terminal (`native-run-projection.ts`);
  - budget pause lifted (`budgets.ts`);
  - company reactivated (`companies.ts`);
  - task-tree hold released (`issue-tree-control.ts`);
  - agent lifecycle ready (`agent-lifecycle-driver.ts`).
- Reconciler (`recovery/ownership-registry.ts`,
`ownership-invariant-report.ts`, `native-finalization-reconciler.ts`):
- registers three new kinds: `wake_request_deferred`, `queued_run` and
`scheduled_retry_run`;
- I4 now reads the closed refusal code (the wake `reason`) of accepted
intents, not free text;
- a new I4 check reports a deferred pause refusal whose pause has lifted
for more than 5 minutes. The worker then promotes it as a backstop;
- a lifted pause inside its 5-minute grace window returns its deadline
through `nextDueAt`, and the worker also wakes on agent-lifecycle
signals (company and agent pause changes). So a missed release event is
still checked.
- `doc/SPEC-implementation.md`: adds the rule "Accepted work intents are
delivered exactly once".

## Verification

Each focused file ran alone in one vitest process (`--maxWorkers=1`) on
embedded Postgres. Results at `2875c85fd2`:

| Question | Loop | Elapsed | Result |
|---|---|---|---|
| Is a comment refused by a pause saved, then delivered once after the
pause lifts? | `heartbeat-held-comment-wake.test.ts -t "pause lifts"` |
8 s | 2 pass. With `queue.ts` from `master`, both fail: no intent is
saved |
| Does I4 use the closed code, and does it catch a stuck deferral? |
`ownership-reconciliation-report.test.ts` | 45 s | 20 pass. This
includes the Phase 2 "retrying once" false positive and the case
"paused, then lifted" |
| No regression on the paths that changed | held-comment (15),
archived-company guard (8), undispatched execution wait (32), deferred
receipt work (45), recovery pause durability (16), native run projection
work (55), tree-control routes and services (19, 1, 7) | 8–334 s each |
All pass |

- Exactly-once: each pause test runs two promotions (a release event,
then the reconciler backstop) and many dispatch passes. It asserts one
delivery. The existing consumption tests (RC-53) still pass.
- Server package typecheck passes.
- Speed: nothing new runs before `turn.start`. The new admission work
happens only on a refusal. Promotion runs in the release transaction and
in the background reconciler.
- Not run here: chaos waves. The coordinating session schedules them on
the shared harness.

## Risks

- `promoteDeferredWorkIntents` moves `updated_at` back for deferred
intents that were refused in the last 30 seconds. A busy company with
many release events can retry refused intents more often. Each retry
re-runs normal admission, and the refusal resets the backoff.
- More release sites now wake run dispatch and stranded-work recovery.
These notifications are coalesced per company.
- Lifting a pause is now the operator's explicit authorization to send
what the pause refused, as Send is after a Stop. When the pause stopped
the task's run, the lifted pause issues the task's next explicit wake,
which adopts the saved message once. Other messages queued behind an
acknowledged Stop keep the existing rule. If Stop recovery still holds
the task, the message waits for that recovery.
- An agent pause's stop sweep keeps the messages that the pause deferred
(`preservePauseDeferred`). Terminate and cleanup stops still end them.
- The backstop check reads only pause refusals (`company.inactive`,
`agent.not_invokable`), because those holds can be checked exactly.
Other deferred kinds keep their existing promotion paths.

Devin FoleyandPaperclip ab82ac0191 fix(workspaces): retire recovered workspace copies after a successful turn (#19979)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - With remote (sandbox) execution, every turn ends by saving the whole
working folder, so the next turn can continue on any sandbox.
> - When a run is cut off mid-turn and its task continues in a new
workspace, preparation attaches the dead run's saved workspace under
`.paperclip-recovered/<operationId>`, so the agent can recover
unfinished work.
> - Nothing ever removes that attachment. Every later save archives and
uploads it again, and a new sandbox restores it again.
> - The attachment is a full workspace, `.git` included, so every save
for that task is roughly twice as big. The extra size lasts until the
task ends.
> - This pull request removes an attachment after a run that was shown
it succeeds, and keeps a retired record so it is never attached or shown
again.
> - The benefit is that affected tasks go back to normal save sizes
after their first successful turn, without changing how recovered work
reaches the agent.

## Linked Issues or Issue Description

**What existing behavior does this improve?**
Recovery attachments in remote workspaces
(`.paperclip-recovered/<operationId>`).

**Subsystem affected**
Server: remote workspace preparation and recovery attachments.

**Current behavior**
`retainRemoteRecoveryAttachments` keeps every recorded attachment on
every later preparation, and no code path removes one. On one hosted
instance, 10 active workspaces carried 18 attachments. One task's saves
went from 746 MB to 1,472 MB at a single save and stayed there. The
largest grew from 709 MB to 3.3 GB. A 3.3 GB workspace needs most of a
10 GB sandbox disk during each save. When a task moves again, the new
attachment contains the older one, so the copies nest.

**Proposed behavior**
Each live attachment records the run it was shown to. When that run has
succeeded, the next preparation removes the attachment from the sandbox,
after checking its exact provenance. It keeps a `retired` record, so:
- a sandbox restored from an older save is cleaned up too;
- the attachment is never attached or shown to an agent again.

**Reason and benefit**
A run that saw the attachment and succeeded had a full turn to use it.
Removing it then returns the task's saves to normal size and frees
sandbox disk.

**Breaking changes**
None. Records written before this change have no `presentedToRunId`.
They are stamped on their next preparation and retired after the
following successful run.

Related: none found.

## What Changed

- `remote-workspace-recovery-attachments.ts`:
- New `retiredRecoveryAttachments`. It returns attachments already
retired, and attachments shown to a different run that has since
succeeded.
- `retainRemoteRecoveryAttachments` removes those attachments from the
sandbox and keeps a `retired: true` record for each.
- `attachPreservedRemoteWorkspaceSnapshots` skips retired operation IDs.
- `workspace-recovery-snapshot.ts`: `attachPreservedWorkspaceSnapshots`
also skips retired operation IDs.
- `remote-workspace-transport.ts`: new `removeRemoteRecoveryAttachment`.
- It reuses the attachment probe's checks: a real directory under the
workspace root, and an exact `provenance.json`.
  - It makes read-only directories writable before removing them.
  - It removes `.paperclip-recovered` once it is empty.
- Anything else at that path fails the preparation instead of being
deleted.
- `remote-workspaces.ts`: computes the retired set before attaching. It
writes `presentedToRunId` on each live record, and keeps retired records
unchanged.
- `heartbeat/workspace-preparation.ts`: never shows retired records to
an agent.
- `doc/execution-semantics.md`: describes retirement.

## Verification

- `pnpm --filter @paperclipai/server typecheck`: exit 0.
- New tests:
- `remote-workspace-transport.test.ts`: removal against real sandbox
commands. It removes an attachment with exact provenance, including a
read-only directory, and leaves sibling attachments. It refuses a
foreign proof or a symlinked directory without deleting anything. It
reports a missing attachment, and removes the empty parent folder.
- `workspace-recovery-preparation.test.ts`, new `retired_followup` case.
The run shown the attachment succeeds. The next preparation, on a fresh
sandbox restored from that run's save, removes the attachment and
records it as retired. A later preparation after a failed run still
neither attaches nor shows it.
- `ordinary_followup` (the agent deleted the attachment itself) now also
ends with a retired record instead of an empty list.
- A retired operation ID is not attached again, even to an empty
destination.
- 13 recovery and remote-workspace suites: 836 passed. With the source
change reverted, the 3 new or changed preparation cases and the 5 new
transport cases fail.

## Risks

- **An agent can lose access to recovered work after one successful
turn.** That happens if a successful run never looked at the attachment.
The source run's saved snapshot in storage is not touched, so an
operator can still recover it.
- **Retired records stay in workspace metadata.** There is one small
record per attachment, and each later preparation sends one sandbox
probe per record.
- **Nested attachments are unchanged.** If no turn succeeds between two
moves, the newer attachment still contains the older one. That older
copy may hold work nobody has recovered yet, so this change does not
drop it.
- Low risk overall: the change is limited to remote workspace
preparation and is fail-closed on provenance.

DottaandClaude Opus 5.5 f6cb3e43f4 fix(admission): admit new work independent of other runs' cleanup and accounting (#19944)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Budget admission decides if new agent work can start in a company
> - Five admission gates waited on the cleanup or accounting of other
runs
> - The restart-chaos campaign found that these gates froze companies
for up to 10 minutes, caused false budget pauses, denied in-run writes,
and dropped wakes, comments and Retries
> - The durable ownership plan (Decision 1) removes the company-wide
accounting gate. It does not narrow it again
> - This pull request removes the five gates. Unfinished accounting now
adds its bounded estimate to exposure
> - The benefit is that one run's unsettled accounting never stops the
other work in its company

## Linked Issues or Issue Description

Refs #19831 (plan, section D), #19838 (inventory, finding 3), #19927
(Phase 2 reconciler data), #19497, #19724, #19826.

**What happened?**
Admission refused new work in these cases, with no reached hard stop and
no pause:
- a terminal run awaited accounting (`waitingRunCount`);
- a native run recovered its accounting (`recoveringRunCount`);
- a budget-owned scope hold awaited reconciliation, after the hard stop
no longer applied;
- a budget input was older than 15 s (`budget_evaluation_work`);
- the predecessor run row of a task was missing (`hasPendingRunCleanup`
failed closed).

**Expected behavior**
Admission never waits on the cleanup or accounting of another run. Only
a reached hard stop, an explicit pause or an inactive company refuses
new work (invariant 3).

**Steps to reproduce**
Make a company with an active budget policy. Leave one failed run with
`cost_accounting_pending = true`. Request work for another agent. On
`master` admission refuses with "Company cannot start work while
completed runs await accounting."

## What Changed

- `budgets.ts`: admission refuses only for a reached hard stop or an
explicit pause. The code removes `observedBlocks`, the
`recoveringRunCount` check, the stale `budgetHeld` refusal and the 15 s
input-age gate. It also removes the unused
`inspectInvocationEligibility`. `reconcileScope` no longer returns
accounting holds.
- `budget-exposure.ts`: removes the `waiting` and `recovering`
aggregates and the own-task subquery. The admission query is smaller.
Unfinished accounting stays exposure: the larger of the held reservation
and the observed cost.
- `budget-evaluation-work.ts`: removes `oldestBudgetInputAt`, which
nothing reads now.
- `execution-blocker.ts`: `hasPendingRunCleanup` returns false for a
missing run row. A run row that is deleted removes its finalization
coordinator and nulls its lease references, so the row owns nothing. A
predecessor that owns a lease or a coordinator still holds the successor
of its own task.
- `recovery/ownership-invariant-report.ts`: the I3 check no longer
mirrors the removed gate. It reports a wake request or a run that was
refused with an accounting-hold reason. Any such report is a regression.
- `doc/SPEC-implementation.md`: adds the product rule "Admission is
independent of cleanup and accounting". `doc/execution-semantics.md` is
aligned.

## Verification

- New `server/src/__tests__/admission-independent-of-cleanup.test.ts`,
on embedded Postgres. It has one case per gate. All six cases fail on
`master` and pass here. A seventh case (an explicit pause still refuses)
passes on both. One case also asserts invariant 3 together with
exposure: two failed runs that each hold a 400-cent reservation fill a
1000-cent budget, and a hard stop still refuses.
- Existing tests that asserted the old gates now assert admission
(invariants 3 and 4): `closed-native-receipt-accounting`,
`budgets-service`, `budget-evaluation-work`,
`heartbeat-held-comment-wake`, `ownership-reconciliation-report`. In
`heartbeat-held-comment-wake`, each saved comment, Retry, assignment and
continuation is delivered exactly once while another run's accounting is
pending. Settling accounting later does not deliver it again.
- All six files pass locally, one file per process. The server package
typecheck passes.
- Speed: admission is on the turn path. This change only removes work
from it: two correlated aggregates, one own-task subquery and one
`budget_evaluation_work` read per policy. No wait or I/O is added before
`turn.start`.
- Not run here: the chaos waves (K13 storm, K6 crash loop, K4 long
holds). The coordinating session schedules them on the shared harness.

## Risks

- Behavior change: work starts while accounting for other runs settles.
Spend stays bounded by the reservation capacity check and the hard stop,
which read the ledger plus observed cost. A run that has no reservation
and no observed cost adds zero exposure until its charge commits. This
is the gap that Decision 1 accepts. Budget enforcement was already best
effort (SPEC 11.6).
- A budget-owned pause with no reached hard stop no longer refuses work
in budget admission. The paused company or agent is still refused by the
existing pause checks until the budget worker lifts the pause.

DottaandClaude Opus 5.5 a4a3e342ec fix(recovery): charge a restart attempt only when the provider accepted a turn and made no progress (#19948)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A run has an execution recovery budget: three provider attempts for
native runs, and two failure retries for legacy runs
> - In the restart chaos campaign, control-plane restarts used up that
budget for runs that were healthy (RC-22, 22b, 22c, 40 and 60)
> - #19720 and #19747 fixed two variants with watermark heuristics, and
legacy interrupted preparation still spent the failure budget
> - The durable-ownership plan (section F, invariant 5) asks for one
rule: charge an attempt only when a recorded outcome proves that
provider work started and no progress followed
> - This pull request adds that rule and moves the native restart charge
and the legacy preparation retry onto it
> - The benefit is that a restart never spends budget for work the
provider never started, while real failure loops and crash loops stay
bounded

## Linked Issues or Issue Description

Refs #19720, #19747, #19856

**What happened?**
A control-plane restart charges a provider attempt by heuristics. The
first crash restart always charges. A later restart charges unless the
previous resume had no start evidence (#19747) or completed work
(#19720). A runner that spawned but whose provider never accepted a turn
counted as started, so a K6 crash loop could still spend the budget.
Legacy runs whose preparation a restart interrupted
(`providerWorkStarted: false`) spent `failureRetries`, the same counter
as real failures (`execution-recovery-attempt.ts`).

**Expected behavior**
An attempt is charged only when the provider accepted a turn
(`turn.accepted` or `turn.started`) and no accepted turn then completed
work. A startup before spawn, a runner that spawned but was never
admitted, and a `turn.start` the provider did not accept are not
charged. The generation-12 cap still bounds uncharged restarts.

**Steps to reproduce**
Start a native run at its last attempt. Kill the controller after the
runner spawns but before the provider accepts a turn. Before this
change, the next restart claim blocks the run with
`execution_recovery_budget_exhausted`.

## What Changed

- New `server/src/services/native-runtime/provider-attempt-outcome.ts`:
the one rule. `readProviderAttemptOutcome()` returns
`provider_not_started`, `provider_started_without_progress` or
`provider_progressed` from run events. `providerAttemptChargesBudget()`
charges only the second. `providerAttemptWindowStart()` starts the
attempt window at the latest `native.process_start_requested`, so
earlier work never counts for a later attempt.
`PROVIDER_ATTEMPT_CREDIT_GENERATION_LIMIT` (12) is the shared cap.
- `restartResumeKeepsAttempt()` (`native-restart-recovery.ts`) now
applies that rule to the attempt the restart interrupted, including the
first restart. It keeps the unstarted-resume carry from #19747, the
reattachment rule (an adopted provider counts as started), the drain
exemption from #19625, and the generation-12 cap. A history entry from
an older release without a recorded position still charges.
- Legacy runs: `interrupted_preparation` is now an uncharged retry lane
(`execution-recovery-attempt.ts`). It keeps its own counter, bounded at
the same cap (12), and never changes `failureRetries`. `retries.ts` uses
the longest transient delay after the second lane attempt.
- `doc/execution-semantics.md` states the rule.
- Accounting has its own "provider work started" readers (inventory
Summary finding 5). Phase 3 owns those; this PR exposes the rule for
them to adopt and does not change them.

## Verification

- `native-runner-restart-recovery.integration.test.ts` (embedded
Postgres, real `claimNativeRestartRecoveries`): 129 passed. New cases,
red on master:
- not charged at the last attempt for a claimed remote bootstrap, a
remote bootstrap retry, and a claimed unlaunched remote run;
- not charged when the runner spawned but was never admitted, and when
the provider did not accept `turn.start`;
- not charged on the first restart when the original attempt already
made progress;
- a normal retry that spawned but was never admitted is not charged, and
earlier work still does not count for it.
- Counter-cases, green on master and with the change: an accepted
`turn.accepted` or `turn.started` with no progress is charged; the
generation cap blocks at the last attempt; crash loops with and without
progress stay bounded; the #19720 and #19747 cases still pass.
- `execution-recovery-attempt.test.ts`: new lane tests (red on master).
- `workspace-recovery-preparation-dispatch.test.ts` (25 passed),
`heartbeat-process-recovery.test.ts` (interrupted-run cases),
`run-dispatch/adapters/postgres.test.ts` (interrupted cases).
- `server` typecheck (`scripts/typecheck-layers.mjs`, low-memory mode):
no errors.
- Not run: chaos waves (the coordinator schedules them on this host),
and the full server suite (CI covers it).

## Risks

- Behavior change: the first crash restart no longer charges when no
accepted turn is recorded. If a crash lands before the controller
projects the provider's `turn.accepted`, that attempt is not charged.
This fails toward more retries, and the generation-12 cap bounds it.
- A legacy preparation crash loop now gets up to 12 retries instead of
2. Each retry still passes the normal issue gates and keeps the
transient delay.
- The new queries use the `(run_id, seq)` index, once per restart claim.
Nothing new runs before `turn.start`.

DottaandClaude Opus 5.5 7fd98682ca fix(workspaces): give every subtask its own execution workspace (#19860)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents split work into child tasks, and each task runs in an
execution workspace (a checkout, branch, or sandbox folder)
> - Since early 2026, a new child task used its parent's realized
workspace by default: the same checkout, branch and sandbox
> - A parent and its child often run at the same time. Two writers in
one folder lose each other's files, the waking parent is cancelled with
`workspace_busy`, and sandbox lease ownership crosses from the parent
into the child, so retained-file recovery refuses the workspace as
ambiguous
> - The product rule is simple: a subtask gets its own workspace,
independent of the parent's saved files. Paperclip never needs to carry
a parent's unmerged changes into a child
> - This pull request makes that the only behaviour on every creation
path, and moves existing shared children to their own workspace on their
next run, with no user or admin action
> - The benefit is that parents and children never block or overwrite
each other, and recovery ownership stays with one task

## Linked Issues or Issue Description

**What happened?**
A child task inherited its parent's realized execution workspace by
default (`createChild` defaulted to `executionWorkspaceInheritanceMode:
"linkage"`, and `issueService.create` fell back from
`inheritExecutionWorkspaceFromIssueId` to `parentId`). When the parent
woke while the child wrote to the shared workspace, the parent run was
cancelled with `workspace_busy`. In sandbox environments, the lease
ownership chain crossed from the parent into the child, and
retained-file recovery refused the workspace with
`allocation_ownership_ambiguous`.

**Expected behavior**
Every new child task gets its own execution workspace, realized from the
project base exactly as a top-level task in that project. It never uses
the parent's checkout, branch, saved snapshot or unmerged changes. A
parent and its descendant never share a workspace by any route.

**Steps to reproduce**
1. Run a parent task in a project with isolated (git worktree) or
sandbox workspaces, so the parent has a realized execution workspace.
2. From the parent run, create a child task with only `parentId` (or
through the runner `create_task` tool, chat suggestions, decision
effects, plugins, or the New sub-task dialog).
3. See that the child's `executionWorkspaceId` is the parent's, with
`executionWorkspacePreference: "reuse_existing"`.
4. Wake the parent while the child runs in a sandbox environment. The
parent run is cancelled with `workspace_busy`.

**Additional context**
Refs #9233 (the existing `strategy_only` opt-out).
The opt-out `executionWorkspaceInheritanceMode: "strategy_only"` already
existed for accepted-plan decomposition. This change makes that
behaviour (tightened to drop a pinned existing branch) the only
behaviour.

## What Changed

- **One rule for every creation path
(`server/src/services/issues.ts`).** `issueService.create` still uses
the parent (or `inheritExecutionWorkspaceFromIssueId`) as a source for
the project, project workspace and workspace *strategy*, but it never
copies the source's `executionWorkspaceId`, `reuse_existing` preference,
or pinned existing branch. All server paths that create a task go
through `create()`/`createChild()`: issue routes (`POST /issues`, `POST
/issues/:id/children`, the run-bound default parent and run workspace
source), runner `create_task`, chat suggestion acceptance, native status
decisions, accepted-plan decomposition, decision effects, plugins
(`ctx.issues.create`), external agents, watchdog follow-ups, monitor
recovery issues, case handoffs and email channels.
- **Explicit ancestor workspaces are dropped.** If a create names an
`executionWorkspaceId` (or an `existing` workspace selection) that an
ancestor of the new task created or is bound to, `create()` drops it and
keeps only the strategy. Older clients and skills that copied the
parent's id keep working and get an independent workspace.
- **`createChild` no longer has a "linkage" mode.**
`executionWorkspaceInheritanceMode` is still accepted from internal
callers and is ignored.
- **`inheritExecutionWorkspaceFromIssueId` decision.** I kept the field
for API compatibility, but it now copies only the source issue's project
and workspace strategy. I removed its workspace-sharing behaviour for
every pair, not only parent/child: the source task and its follow-up can
run at the same time (the runner, watchdog and status-decision callers
all create the follow-up while the source run is live), so sharing would
again let two tasks write one folder. Explicit sharing between unrelated
tasks stays available through an explicit `existing` workspace
selection.
- **New `server/src/services/task-workspace-lineage.ts`.**
`buildIndependentTaskWorkspaceSettings` (strategy only: mode,
environment, runtime, network egress, shared-workspace concurrency, base
ref, branch template, commands; no `reuse_existing`, no
`operator_branch`, no `existingBranch`), `loadTaskLineageIssueIds` (the
parent chain plus, for a task that depth placement put beside its
requester, the requester's chain via `privacyParentIssueId`) and
`isAncestorExecutionWorkspace` (the workspace's `sourceIssueId` is in
that lineage, or a lineage issue is bound to it). A child in another
project does not take the parent's strategy.
- **Upgrade-safe rebind at admission.**
`executionWorkspaceService.releaseAncestorWorkspaceBindingAtAdmission`
runs at the same admission point as the pending workspace selection
(`heartbeat.ts`). For a child (or a flattened task beside its requester)
that an older release bound to an ancestor's workspace, it clears the
child's binding (keeps the project workspace and strategy, bumps the
binding revision) so the run realizes the child's own workspace. It does
nothing while another run of the child is running, while the child's
earlier run still owns workspace finalization or recovery, for native
restart/lease-owner recovery, for a process-loss retry, or for a Retry
that keeps the current workspace. The parent and its workspace are never
changed.
- **Projects without a project workspace (per-task repository
acquisition).** A parent with no project workspace worked in its own
task files, so its settings (for example `isolated_workspace`) do not
describe the project base. A child of such a parent, and an older child
released from one, takes the project's defaults exactly like a top-level
task, instead of an isolated mode that would resolve to a git worktree
with no git base ("needs a project / project workspace"). When the
child's new workspace is created at admission,
`executionWorkspaceRepositoryService.prepareForAdmission` repeats the
parent's (or requester's) repository requests as the child's own pending
requests (identity, URL, catalog id and requested ref only; no pinned
commit, branch or files). The normal acquisition path then clones a
fresh copy into the child's task files with the child's own access
checks. This runs only for a workspace created by that admission, so
existing tasks never gain repositories.
- **UI.** The New sub-task dialog no longer pre-selects the parent's
workspace. `buildSubIssueDefaults` drops `executionWorkspaceId` and
`reuse_existing`, and derives the parent's independent mode
(`shared_workspace`, `isolated_workspace` or `agent_default`) from its
preference, saved settings or current workspace. The "This sub-task will
no longer use the parent task workspace" warning is removed.
- **Contracts and docs.** Shared validator and plugin SDK comments
describe the new meaning of `inheritExecutionWorkspaceFromIssueId`.
Updated `doc/execution-semantics.md` (new rule in §6 and a wording fix
in the retained-sandbox paragraph), `doc/SPEC-implementation.md` (child
workspace rule, requester keeps *strategy* inheritance, watchdog
follow-ups), `doc/SPEC.md` (task workspace ownership),
`docs/specs/external-task-protocol.md`, `skills/paperclip/SKILL.md`
(step 9 and the workspace bullet),
`skills/paperclip/references/issue-workspaces.md`, the CEO onboarding
`HEARTBEAT.md`, and the plugin SDK README.

### Previous-release story (`rules/upgrade-safe-run-state.mdc`)

- **Migrated on next admission.** A child that the previous release
bound to its parent's (or any ancestor's) execution workspace keeps that
binding until its next normal admission. Then the server clears the
binding and the run realizes the child's own workspace from the project
base. No schema migration is needed. No user or admin action is needed.
- **In-flight writers finish first.** A running child is not
interrupted. Its current run, its native restart recovery (admitted
native input or lease owner), a process-loss retry, and a Retry that
keeps the current workspace all finish in the shared workspace. While a
child's earlier run is still running or its workspace finalization or
recovery is unsettled, the binding stays and a later admission releases
it.
- **No files are dropped.** The release changes only the child's binding
row. The parent keeps its binding, and the shared workspace row, folder,
branch and saved snapshots are not touched. Anything the child left
there stays in the parent's workspace.
- **No new refusal codes.** Saved run identity (native execution input,
leases, checkpoints) is not changed or refused; the rebind only affects
new admissions.

## Verification

- New `server/src/__tests__/subtask-workspace-independence.test.ts`
(embedded Postgres): `create` with `parentId`, `createChild` with no
mode / `"linkage"` / `"strategy_only"`,
`inheritExecutionWorkspaceFromIssueId` pointing at the parent, explicit
parent and grandparent `executionWorkspaceId`, a non-child follow-up,
and unchanged top-level defaults and explicit top-level reuse. 7
creation cases fail on `master` and pass with this change. Admission
cases: an old-release child is rebound while its parent is running and
the parent keeps its workspace; a running child is not rebound (deploy
lands mid-run); an unrelated explicit share is kept; the parent is never
rebound.
- New heartbeat case in
`server/src/__tests__/heartbeat-workspace-busy.test.ts`: an old-release
child bound to its running parent's workspace in a sandbox environment
runs to `succeeded` with no `workspace_busy`, gets a new workspace, and
the parent run and binding stay unchanged. It fails on `master` (the
child waits with `workspace_busy`).
- Updated tests that asserted the old inheritance in
`issues-service.test.ts`, `task-workspace-binding.test.ts`,
`chat-project-tools.test.ts`, `task-workspace-child-trust.test.ts`,
`heartbeat-git-restore-point-resume.test.ts` (a child bound to a closed
parent's expired workspace now starts from the project base and leaves
the parent's restore point alone), and
`ui/src/lib/subIssueDefaults.test.ts`. Remote-workspace reservation,
continuation and writer-wait suites now seed the older-release shared
shape directly (or an unrelated explicit share), so those safety paths
stay covered.
- `npx vitest run` on the changed suites and about 45 related server
suites (heartbeat workspace, recovery admission, issue routes, routines,
plugins), `ui` `subIssueDefaults` and `NewIssueDialog` tests, `pnpm
check:token-gates`, `pnpm -r typecheck`.

- New
`server/src/__tests__/heartbeat-subtask-acquired-repository.test.ts`: a
project with no project workspace, a parent whose task files hold an
acquired repository with an unmerged change, and a child (new, and the
older-release shape bound to the parent's workspace) that runs to
`succeeded` in its own task files with a fresh clone at the project base
and its own ready repository receipt. The parent's checkout keeps its
change. Both cases fail on the previous head with "needs a project /
project workspace".

## Risks

- **Project-level configuration still applies to children exactly as to
top-level tasks.** In a project configured for `shared_workspace`, every
task (top-level or child) uses the project's one folder under the
existing shared-workspace concurrency policy. A branch that the project
itself pins applies to every task in the project. This PR removes only
the parent-to-child carry-over of the realized workspace; it does not
change those project defaults.
- **Standalone follow-ups that an older release bound through
`inheritExecutionWorkspaceFromIssueId`** are migrated only when the
source is in their recorded lineage (parent or privacy parent). Others
keep their explicit share and the existing writer-wait serialization.

- **Behaviour change for agents that relied on a shared checkout.** A
child or follow-up no longer sees the parent's unpushed or uncommitted
changes. Agents must push or merge code they want a subtask to build on.
The skill and onboarding text now say this.
- **Explicit ancestor workspace ids are silently dropped** instead of
rejected, so older clients do not break. The task gets an independent
workspace.
- **First run of a migrated child starts from the project base.** If an
older child had uncommitted work in the parent's workspace, that work
stays in the parent's workspace and is not copied into the child's new
workspace.
- **Admission adds one indexed read** for tasks with a parent and a
bound workspace; the locking transaction and ancestor query run only
when the bound workspace was created by another issue.

continue by themselves, with no lost saved work and no admin action.

## Linked Issues or Issue Description

Refs #19840 (removes the "inspect the run and its environment" text and
keeps Retry; this change removes the need for that Retry).

**What happened?**

A child task ran in a reusable sandbox that it inherited from its parent
task. The run saved a checkpoint, wrote more files, and then failed to
save them. Retained-file recovery refused the source with
`allocation_ownership_ambiguous`, because the lease history of the
sandbox crosses into the parent task. The hold was exhausted after one
attempt. Retry made a new generation that failed the same way. The task
stayed blocked with `saved_work_recovery_failed`,
`workspaceRepairRequired: true`, and the failed run still the dirty
writer of the workspace. A second task had a stale exhausted hold for a
run whose files a sibling recovery action had already saved. That hold
also kept the task from continuing.

**Expected behavior**

Recovery works without a person. When the source cannot be verified, the
task continues from its last saved version. The unverified files are not
applied, but they stay available. A stale hold whose files were already
saved settles as recovered.

**Steps to reproduce**

1. Use a native run with a remote workspace whose reusable sandbox lease
history includes a lease of another task.
2. Let the run save a checkpoint, write more files, and fail its final
save.
3. Let retained-file recovery run, or press Retry.
4. Before this change, the hold is exhausted with
`allocation_ownership_ambiguous` and the task stays blocked.

**Paperclip version or commit**

Observed on deployed builds that include `630411af53`. Holds saved by
the Nov 3–6 releases have this shape.

## What Changed

- New `server/src/services/workspace-recovery-fallback.ts`:
- `continueFromLastSavedWorkspace` runs when a hold is exhausted by a
permanent source refusal: `allocation_ownership_ambiguous`,
`source_binding_invalid`, `source_unavailable` or
`historical_source_missing` with retry class `service_required` or
`use_alternative_strategy`. It applies only to remote workspace sources
in the `prepared` state.
- Quarantine (secrets omitted under the workspace file policy: `.env`,
keys, repository metadata, dependency directories): if the retained root
is readable, the worker copies it with the existing read-only capture
(no write to the sandbox), converts it to a `.tar`, stores it, and
attaches it to the task as `unverified-files-run-<runId>.tar`. A
`workspace_recovery_quarantine` operation records it as `verified:
false, applied: false`. If the root is not readable, the worker records
a closed reason label.
- Stop proof: every allocation of the source run must carry a provider
stop receipt. A missing receipt is obtained through the same stop-only
cleanup as normal recovery (`prepareSandboxStopAndRetain` /
`prepareHistoricalSandboxStopVerification`,
`retryPendingSandboxTeardown`, `settleStopOnlyCleanup`). A sandbox that
another lease holds (`active` / `pending_cleanup`) is never read or
stopped from here; the hold waits.
- One transaction (lock order: task, coordinator, run, recovery action,
workspace) re-checks all facts including the stop receipts, abandons the
epoch, resolves the hold with the named outcome
`retained_source_unverifiable_continued_from_last_saved`, records an
`executionReconciliation` decision with `retainedSourceFallback`, and
denies native replacement. A Blocked task belongs to the hold only while
the hold's own `workspaceFinalizationBlock` receipt still owns that
status version, or, for receipt-less holds saved by older releases,
while the block was set by the run's terminal failure (within its
finalization window) and no status decision followed. Only then is the
task restored to `todo` and a continuation scheduled; a newer block is
kept and no continuation starts. The decision carries machine
`workspaceRepairEvidence`, which the reconciled admission requires for
runs with a restore failure.
- Continuation: with no waiting user input, the hold uses
`continuationDelivery: "pending"`, so the existing reconciled delivery
starts one continuation. Waiting user input continues the task itself
(`not_requested`), so there is never a second continuation.
- Agent note: the decision's `outcomeEvidence` (part of the
continuation's recovery outcomes) says that the run's unsaved changes
could not be verified and were not applied, where the attached copy is,
that the agent should check what to redo, and that completed external
actions must not be repeated.
- `settleSiblingRecoveredHold`: an exhausted hold whose run has a
verified repair receipt from a different recovery action settles as
recovered. It runs for every exhausted hold, including adoptable native
sources. A sibling marked recovered whose receipt no longer verifies
records a permanent deferral, so discovery does not reselect it.
- Deferral: when the fallback cannot settle yet, the hold records
`retainedSourceFallbackCheck` (reason, generation, count). Transient
reasons (live writer, running operation, missing stop, sandbox in use,
pending status effect, lock busy, storage failure) are checked again
after 5 minutes, at most 12 times. Permanent reasons (uncertain external
action, non-remote source) wait for new input, Retry or a new
generation. Storage or database failures after a successful read are
retryable and never recorded as "unreadable".
- New `server/src/services/workspace-recovery-fallback-discovery.ts`:
SQL for pending and due fallbacks. `retainedWorkspaceCandidates` (the
production worker's obligations sweep) and `nextWorkspaceRecoveryAt`
(its scheduler) include them, so the worker reaches old holds without
saved input.
- New `server/src/services/remote-workspace-epoch-abandonment.ts` (kept
out of `remote-workspaces.ts`, which is near 1,000 lines): authority
transition `abandonUnverifiedRemoteWorkspaceEpoch`. It clears the writer
and the dirty flag, keeps `snapshotId`, drops `location`, advances the
epoch, clears `providerRef` and the migration root, and records the
abandoned epoch. The next preparation restores the last save into a new
`<workspace>-<epoch>-<lease>` root.
- `server/src/services/workspace-recovery.ts`: hooks. An exhausted hold
first tries the sibling settlement, then the fallback (under the
existing workspace ownership lock). A fresh permanent refusal in an
attempt runs the fallback in the same pass, under the same ownership.
- `remote-workspace-transport.ts`: export the existing read-only
capture.
- `packages/shared`: optional `retainedSourceFallback` on
`ExecutionReconciliation`.
- `doc/execution-semantics.md`: document the fallback.
- No new polling or worker: the fallback runs inside the existing
retained-workspace recovery pass
(`rules/sleep-aware-background-work.mdc`).

Safety:

- The cross-task lease check (`retiredReusableLeasePredecessors`) is
unchanged and stays strict. Unverified files are never applied.
- No second executor: the source run, its controller and its finalizer
must be stopped. A live writer of the task or workspace, or a running
workspace operation, keeps the hold.
- No repeated external side effects: pending status effects,
non-completed or unknown API receipts, and uncertain tool invocations
keep the existing reconciliation path. The continuation keeps the
existing API receipt fences.
- Never overwrite another run's files: only the exact epoch that the
failed run wrote is abandoned, and the old root is never reused.
- Bounded and idempotent: a settled hold is never revisited. The
quarantine record is reused. A changed generation or revision leaves the
hold unchanged.

Previous-release story (`rules/upgrade-safe-run-state.mdc`): holds saved
by earlier releases carry forward. A hold saved by the Nov 3–6 releases
(`systemRecovery` exhausted with `allocation_ownership_ambiguous` /
`service_required`, board owner, old admin text) takes the fallback on
the next worker pass after deploy (restart sweep, Retry, or a new
message). No migration is needed. Refusals that do not qualify keep
today's behavior. The only new persisted shapes are additive:
`retainedSourceFallback` and `siblingWorkspaceRecovery` on the hold,
`remoteWorkspaceAbandonedEpochs` on the workspace, and a
`workspace_recovery_quarantine` operation. Earlier releases ignore them.

## Verification

- `cd server && npx vitest run
src/services/workspace-recovery-fallback.test.ts` — 15 tests:
- cross-task hold, saved by the previous release and refused fresh:
continues from the checkpoint snapshot, the quarantine `.tar` holds the
unverified file, the epoch is abandoned, `getExecutionBlocker` is
`null`, the task is `todo`, explicit continuation is not blocked by
`saved_work_recovery_failed` or `workspace_repair_required`, one
reconciled continuation is delivered, and the next writer restores into
a new root while the old root keeps its files;
  - unreadable root: continues and records the reason;
- idempotency: a second pass changes nothing and delivers no second
continuation;
  - waiting user input: no second continuation;
- negatives (live writer, pending side effect, uncertain external
action, sandbox held by another lease): the hold stays, the authority is
unchanged, nothing is attached or delivered, the deferral reason and
recheck time are recorded;
- an allocation without a stop receipt is stopped (stop-only) before the
hold settles;
- the production worker (`reconcileRetainedWorkspaces` with
`obligationsOnly`) and `nextWorkspaceRecoveryAt` discover and settle an
old hold with no saved input; a transient deferral is not revisited
until due, then settles;
- an old-release hold without a Blocked receipt keeps its status; a
current hold with the receipt is restored to `todo`;
- stale exhausted hold with a sibling-saved receipt settles as
recovered; one whose sibling receipt no longer verifies is recorded and
no longer discovered;
- a newer Blocked decision is kept and no continuation is delivered,
while the file hold settles;
  - the attached copy omits `.env` and key files.
- RED: with `workspace-recovery.ts` and `system-recovery.ts` reverted to
master, all tests fail.
- Regression suites pass: `workspace-recovery-warm-handoff`,
`workspace-recovery-retry-copyback`,
`workspace-recovery-preparation-gates`, `workspace-recovery-source`,
`task-retry`, `execution-blocker-read` (288 tests), and
`workspace-recovery-admission`, `workspace-recovery-preparation*`,
`remote-workspaces.integration`, `native-failed-workspace-recovery`,
`remote-workspace-transport`, `workspace-restore-repair-route` (683
tests).
- `server` typecheck passes.

## Risks

- A task now continues without the unverified changes of its failed run.
The agent receives a note and the attached copy, so it can redo or
re-apply the work. This replaces an indefinite block.
- Abandoning an epoch on a workspace shared with a parent task also
moves the parent to the last save. This is correct: the unverified
changes are not part of the saved lineage.
- Clearing the migration root means sessions bound to the old root start
fresh. The fallback continuation already forces a fresh session.
- The quarantine capture reads a sandbox that can be shared with another
task. It writes nothing there, and it verifies the copy against
inventories taken before and after.

DottaandClaude Opus 5.5 177f642da7 fix(recovery): continue native runs that failed before their first claim (#19911)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs go through a coordinator claim before any provider work
starts
> - A run can fail before that claim, for example while it restores the
previous harness backup
> - The failure path then records a no-replay hold, as if the run had
acted
> - Workspace recovery saves the files, but the task stays blocked and
asks a person to send a message
> - Recoveries must continue without a human step when no side effect is
possible
> - This pull request lets the existing safe-replacement worker continue
such runs once, after their files are saved
> - The benefit is that these tasks resume automatically, and runs that
may have acted keep today's reconciliation

## Linked Issues or Issue Description

**What happened?**
Native runs that failed before their first coordinator claim were never
continued automatically. They had no claim, no provider process and no
provider or tool events. Their result recorded `executionRecovery: {
kind: "bootstrap", providerWorkStarted: false }`. The failure path still
moved the coordinator to `terminal_failure` with
`native_continuation_requires_reconciliation` and recorded a resolved
`preserve_without_replay_v1` hold (replay blocked, board owner).
Workspace recovery then saved the files, but the next action stayed
"Saved work recovered. Send a message to continue."
`nativeReplacementPending` accepted only a few failure codes, and the
interrupted-preparation path covers only legacy runs.

**Expected behavior**
When a native run provably failed before its first claim, Paperclip
continues it once, automatically, after its files are saved (or when it
had no workspace to save). Runs with a claim, a process, a provider or
tool event, or recorded provider work keep the existing reconciliation.

**Steps to reproduce**
1. Start a native run with a remote workspace.
2. Make it fail before `native.coordinator.claim` (for example, abort
the harness-backup restore).
3. Let workspace recovery save the files.
4. See that the task stays blocked and asks for a message.

**Paperclip version or commit**
Observed on e2d490c61. Reproduced on master before this change.

Refs #19906 (fixes the restore deadline that caused the observed
failures).

## What Changed

- `native-safe-replacement.ts`: add one class-level candidate, "failed
before its first claim". It requires the
`native_continuation_requires_reconciliation` coordinator at attempt 0
and controller generation 0, with no lease, assessment, decision or
result.
- The candidate also requires no process identity, no `sessionIdAfter`,
no provider/turn/item/tool/`run.result` events, no tool invocations,
`providerWorkStarted` not `true`, no Stop or cancellation, no explicit
user continuation, and no later run for the task.
- A no-replay hold must have completed file recovery (the existing
`completedWorkspaceRecoveryCondition`). A blocked task must carry this
failure's block receipt at the current status version.
- Discovery checks saved-file evidence (snapshot, stopped sandbox) or a
workspace-less run before it selects the candidate.
- The reconciler skips the stopped-session probe for this class. It
feeds the decision with known failure meaning and a complete effect
inventory, since no provider ran. It rechecks the candidate under the
task and coordinator locks before it inserts the successor.
- The successor is the existing fresh-session `native_safe_replacement`.
Its context carries `nativePreClaimContinuationOf`, so a failed
successor is not continued again. The existing transaction resolves the
hold (`replay: verified_safe_replacement`) and restores the task block.
- `doc/execution-semantics.md`: describe the rule.

Previous-release story: holds recorded by earlier releases (resolved,
`replay: blocked`) carry forward. The test seeds that exact shape. No
schema or persisted identity changes.

## Verification

- `cd server && npx vitest run
src/services/native-preclaim-continuation.test.ts`
- Before the fix: "continues automatically exactly once after its saved
work is recovered" fails (no successor).
  - After the fix: all 9 tests pass.
- The tests cover: the staging shape with an old-release hold continues
exactly once under concurrent and repeated sweeps; it waits for saved
files; it does not chain from its own successor; and it keeps
reconciliation when the coordinator claimed, a provider event exists, a
tool call started, provider work is recorded, a process started, or a
later run owns the task.
- `npx vitest run
src/services/native-runtime/native-safe-replacement.test.ts` passes (62
tests).
- `pnpm --filter @paperclipai/server typecheck` passes.

## Risks

- The successor uses a fresh provider session, like the other safe
replacements. History comes from `retryOfRunId`.
- The new predicate adds one indexed `not exists` on `heartbeat_runs
(company_id, context_snapshot->>'issueId', created_at)` per candidate.
It runs only for the narrow pre-claim failure code.
- A run whose prepared workspace uses the older `nativeWorkspaceSync`
descriptor without remote-workspace evidence stays held, as today.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, with tool use and code
execution in Claude Code.

DottaandClaude Opus 5.5 f439150cb3 fix(recovery): limit the null-host owner fallback to single-host servers and record each use (#19883)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - #19868 and #19871 made restart recovery judge a recorded pid only in
the PID space that recorded it
> - Rows saved before those host columns existed have no recorded host.
They kept the previous local dead-pid proof, so in-flight native runs
would not be stranded at upgrade
> - On an ephemeral (multi-host) server that fallback is unsafe: the row
may have been written on another host
> - This pull request limits the fallback to single-host servers,
records every use, and gives ephemeral servers a working board action
> - The benefit is that single-host upgrades still recover on their own,
multi-host servers never accept a cross-host proof, and the next release
can remove the fallback with evidence

## Linked Issues or Issue Description

**Bug description**
After #19868 and #19871, a `native_run_finalizations` row with
`controller_host_hash = null`, or a run with `process_host_hash = null`,
still accepted "the pid is dead here" as proof on every server. That
includes an ephemeral server, where the row may come from another host.
Nothing recorded how often the fallback was used, so it had no safe
removal path.

**Expected behavior**
- Single-host server: the fallback applies for one release, and each use
writes a `legacy_host_unknown_dead_pid_proof` activity-log entry.
- Ephemeral server (`PAPERCLIP_EPHEMERAL_SERVER=true`): the row is
unprovable, and the board has an action to confirm the previous server
stopped.
- A mismatched host is always unprovable.

Refs #19868, #19871, #19846

## What Changed

- `native-restart-recovery.ts` `evaluateNativeControllerTakeover`:
- A coordinator row with `controllerHostHash: null` returns
`controller_host_unrecorded` when `ephemeralServerEnabled()` is true.
- Otherwise a pid proof from that row carries `legacyHostFallback:
true`.
- `operator_attested` is accepted as proof
(`operator_attested_controller_stopped`).
  - Receipt-built owners, which have no host key, are unchanged.
- New `recordLegacyHostFallbackProof` writes the activity-log entry. It
is not a run-log event: run events are progress evidence for restart
recovery's crash-loop credit, and the record must not change any
recovery decision. It is called from restart recovery, the
dead-controller result-lease release, native retirement, and remote
warm-session recovery.
- New `native-controller-host-recovery.ts`:
- `requestNativeControllerStopConfirmation` (board-owned
`native_controller_host_unverified` recovery action, idempotent, never
displaces another active action).
- `confirmNativeControllerStopped`. It verifies the exact recorded
controller and stamps `operator_attested` with compare-and-set. It then
resolves the action, wakes live-run recovery, and logs
`issue.native_controller_stop_confirmed`.
- Route `POST /issues/:id/recovery-actions/confirm-controller-stopped`.
It is board-only and requires `runtime:confirm_owner_stop`. Generic
`restored`/`false_positive` resolution of this cause is refused. A
shared `confirmNativeControllerStoppedSchema` validates the body.
- UI: `WorkspaceExportRecovery` reuses the "Confirm the previous server
stopped" control for this cause, and the generic recovery card hides it.
Adds the `issuesApi.confirmControllerStopped` client call.
- `recovery/service.ts` orphan reaper: a null `process_host_hash` is
judged only when not ephemeral. A successful use records the entry
best-effort, after the terminal write. On an ephemeral server the run is
left to its existing Stop control.
- `ephemeralServerEnabled` moves to a leaf `ephemeral-server-mode.ts`
(re-exported by `ephemeral-server-contract.ts`). Importing the contract
module from recovery code created an import cycle in the runner child
process.
- The new route is registered in OpenAPI.
- `doc/execution-semantics.md`: documents the host rule and the
one-release sunset.

## Verification

- `native-restart-recovery.test.ts`: null host on a single-host server
is released with the flag. Null host on an ephemeral server is
unprovable. A mismatched host is unprovable in both modes. An attested
controller is accepted. Receipt owners are unchanged.
- New `native-controller-host-recovery.test.ts` (embedded Postgres):
  - The fallback writes the activity-log entry and no run event.
  - Ephemeral mode creates exactly one board action.
  - A wrong run id is refused.
- Confirmation stamps the attestation, after which takeover is allowed.
The action resolves and the activity is logged. A second confirmation is
refused.
- `recovery-stale-issue-lock-sweep.test.ts`: on a single-host server a
null host is terminalized and records one event. On an ephemeral server
it is left alone with no event. The existing audit-failure case still
clears the lock.
- `WorkspaceExportRecovery.control.test.tsx`: the controller
confirmation posts to `confirmControllerStopped` and never to the
copyback endpoint.
- Locally: these suites plus `remote-warm-session-recovery`,
`native-controller-recovery.integration` and
`native-startup-cleanup-recovery` (136 passed), and after the CI fixes
`native-runner-restart-preparation` and `native-runner-restart-recovery`
integration, `openapi-routes` and the suites above (256 passed); the UI
recovery suites (52 passed); `node scripts/typecheck-layers.mjs` with no
errors in the touched files; `pnpm check:token-gates` clean.

## Risks

- Previous-release story: no schema change. Null-host rows saved by
earlier releases recover as before on single-host servers, now with an
event, and wait for the board on ephemeral servers. The next release
removes the fallback; the event count shows whether any rows remain.
- On an ephemeral server, a null-host orphaned run process is not reaped
automatically. The operator uses Stop. That is the intended "unprovable"
outcome.
- A board confirmation is an attestation. It applies only to the exact
recorded controller (boot id + pid) and only while the host is still
unrecorded.

code execution in Claude Code.

DottaandClaude Opus 5.5 738058553f fix(recovery): resume a continuation that never launched its runner in its own sandbox (#19850)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A chat follow-up on a remote native task runs as a continuation: it
starts from its predecessor's saved provider session and, for a warm
session, copies the predecessor's runner process identity onto the new
run
> - When the continuation fails before it asks for a runner of its own,
its due same-run retry sees a recorded process identity and reattaches
to "this run's" runner. That runner never existed, so reattachment
always fails with `native_remote_recovery_lease_mismatch` and the task
is blocked
> - On staging, 34 OpenCode runs on 31 tasks failed this way in one
evening. Each first attempt failed while staging its provider pack,
recorded no runner start, and kept its own sandbox lease active
> - This pull request proves that shape from durable state, retires the
inherited identity, and resumes the run the way its failed attempt ran,
in its own retained sandbox
> - The benefit is that these retries recover automatically, without a
second sandbox and without the unsaved-work hold, while every run that
may hold its own provider work keeps verified reattachment

## Linked Issues or Issue Description

Refs #19839, Refs #19399, Refs #19755, Refs #19779, Refs #19827

**What happened?**
A remote OpenCode chat continuation failed during provider-pack staging.
The run had no runner start event, no process identity event, no
controller checkpoint, and no provider event of its own. Its saved
session (no active turn, no pending request) and its process identity
were inherited from the previous run. Its failure detail recorded
`providerEventsExist: false`, and its own sandbox lease stayed active.
The due same-run retry chose `reattach_remote_runner` because a process
identity was recorded. Reattachment failed with
`native_remote_recovery_lease_mismatch`, and the run ended in
`native_continuation_requires_reconciliation`.

**Steps to reproduce**
1. Continue a warm remote native session so the new run inherits the
predecessor's runner process identity and saved session.
2. Fail the new run with a retryable error before it requests a runner
(for example during provider-pack staging).
3. Let the same-run retry become due. Recovery requests
`reattach_remote_runner`, and reattachment fails.

**Expected behavior**
The retry resumes the run the way its failed attempt ran, in the same
sandbox, and continues the inherited provider session. A run with any
provider work, runner start, or controller checkpoint of its own keeps
verified reattachment.

## What Changed

- New
`server/src/services/native-runtime/native-inherited-runner-retry.ts`:
- `retireInheritedRemoteRunnerIdentity` locks the issue, the
coordinator, then the run (the same order as same-run resumption). It
retires the recorded process identity only when all of these hold: the
coordinator is a result-less, unowned `exact_checkpoint_resume` retry
with `providerEventsExist: false`; the run has no runner start, process
identity, adapter invocation, tool start, runner event, controller
checkpoint, provider event or provider session of its own; the saved
session has no active turn and no pending runtime request; and a settled
predecessor of the same native session recorded the exact same process
identity (PID, group, start time).
- It records `nativeInheritedRunnerRetirement` on the run profile, with
the run's own sandbox location when that lease is still active, and an
`inherited_runner_never_launched` lifecycle event.
- `readInheritedRunnerRetainedSandbox` returns that sandbox only while
it still matches the run's saved remote location.
- `heartbeat/recovery.ts`: a due remote retry calls the retirement
first. It returns `retired`, `not_applicable` or `transient`. A retired
run (including one a concurrent sweep already retired) goes to the
ordinary same-run resume (`claimNativeSessionResumptions`), with every
existing admission gate. A lock timeout or database error is
`transient`: the sweep defers the run and checks again, and never falls
back to reattachment. Any other run keeps verified reattachment.
- `heartbeat/workspace-preparation.ts`: an ordinary same-run resume with
a retired inherited runner acquires its retained sandbox through the
existing exact-lease path (`reattachRemoteLease`), which validates and
resumes that lease and never acquires a replacement. It acquires as an
ordinary resume does only when the exact-lease failure proves the
sandbox is unusable (`stage=environment_acquire|environment_resume`,
`field=lease|lease_status|lease_expired|provider_lease_id`). Any other
failure, such as a scope mismatch on a live lease, is kept and acquires
nothing.
- New `server/src/services/retained-sandbox-absent-error.ts`: a sandbox
provider's resume reply with no provider lease and `expired: true` (the
reply Daytona and other providers send when the sandbox is gone) now
throws `RetainedSandboxAbsentError`. Every other mismatched reply keeps
the existing error. The exact-lease reattachment in
`environment-run-orchestrator.ts` maps it to
`native_remote_recovery_lease_mismatch: stage=environment_resume
field=lease_expired`, so the same-run resume above acquires as an
ordinary resume when the provider has removed the retained sandbox. A
transient resume failure is not treated as absence and never acquires
another sandbox.
- `native-restart-recovery.ts` exports the existing
`hasNativeExecutionStartEvidence` so both paths use one definition of
"execution reached a runner".
- `doc/execution-semantics.md` documents the rule.

## Previous-release state

- No schema change. The new profile field is additive.
- A run saved by an older release without `providerEventsExist`, without
a native session ID, or without a matching predecessor keeps verified
reattachment. That path is unchanged. When it loses its runner, it still
requests the user's Retry once (#19399).
- A run that an older release left with its own runner start, controller
checkpoint or provider event keeps verified reattachment, because its
outcome may be ambiguous.
- A profile without the new marker never changes acquisition.

## Verification

- `npx vitest run server/src/services/heartbeat/recovery.test.ts -t
"never launched its own runner|keeps verified reattachment"` (embedded
PostgreSQL):
- Staging shape (inherited session and process identity, no runner start
of its own, saved remote workspace, active own lease, recorded PID).
Before the fix: fails, because recovery requested reattachment. After
the fix: passes. The PID fields are cleared, the marker names the
predecessor and the retained lease, `executeRun` is called once with a
plain `nativeLeaseOwner` claim, the run still has exactly one (active)
lease, and no process is signalled.
- Negatives, passing before and after: a provider turn of its own, a
runner start of its own, a controller checkpoint of its own, no matching
predecessor, a pending runtime request in the saved session, and a
failure detail without `providerEventsExist`. Each keeps verified
reattachment and gets no marker.
- `npx vitest run
server/src/services/heartbeat/workspace-preparation.test.ts -t "retained
sandbox|retired inherited"`:
- A retired inherited runner acquires its retained sandbox with
`reattachRemoteLease`. Before: fails. After: passes.
- When the retained sandbox is gone, it acquires as an ordinary resume.
Before: fails. After: passes.
- Without the marker, acquisition is unchanged (passes before and
after).
- A `nativeWorkspaceSync` reference also resumes its retained sandbox. A
live lease's `lease_scope` failure is kept and acquires nothing.
- `recovery.test.ts` also covers a second retirement call (returns
`retired`, one event) and a held issue lock (defers; no reattachment, no
dispatch, PID kept).
- `environment-runtime.test.ts`: on exact resume, only a provider reply
with no lease and `expired: true` (with or without a workspace sentinel
mismatch) is `RetainedSandboxAbsentError`; a different lease or a reply
without `expired` keeps the existing error.
`environment-run-orchestrator.test.ts`: confirmed absence becomes
`stage=environment_resume field=lease_expired` and acquires nothing.
- Affected suites pass locally: `recovery.test.ts`,
`workspace-preparation.test.ts`,
`heartbeat-native-remote-failure-retention.test.ts`,
`workspace-recovery-retry-copyback.test.ts`,
`native-runner-restart-recovery.integration.test.ts`. `pnpm --filter
@paperclipai/server typecheck` passes.

## Risks

- **No second executor.** The rule applies only when this run never
requested a runner, so no runner of this run exists. The predecessor
must be settled, and its identity is matched exactly. The resume then
takes the normal same-run claim, which holds the issue lock and
admission gates.
- **No repeated side effects.** The run has no provider event, turn or
tool start of its own. A saved session with a pending runtime request or
an active turn keeps verified reattachment. The resumed provider session
goes through the existing provider recovery, which refuses a pending
side-effecting call with a permanent, named code.
- **Bounded.** The retirement takes effect once per run, because
afterwards the run has no recorded identity. A contended retirement
waits for the next sweep. Further failures use the existing
three-attempt provider budget.
- I did not run a live Daytona sandbox, or a full preparation through a
real sandbox plugin, through this path. The orchestrator's exact-lease
checks are covered by its own unit tests. The evidence is recovery and
preparation tests on a real database with the staging run shape.

DottaandClaude Opus 5.5 84908d176b fix(recovery): name the failed check in native_remote_recovery_lease_mismatch (#19839)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Remote native runs execute in a sandbox, and recovery can reattach a
run to its original sandbox runner
> - Reattachment checks the saved lease, workspace, and runner identity
in five places. Each failed check throws the same bare
`native_remote_recovery_lease_mismatch`
> - On staging, 34 OpenCode runs on 31 tasks failed with this bare error
in one evening. The run records could not show which check failed, so
the cause could not be confirmed from the run alone
> - This pull request makes every producer name the failed step and
field with closed values
> - The benefit is that an operator and the next investigation can see
which reattachment check failed, without new logging or identifiers in
the error

## Linked Issues or Issue Description

Refs #19399, Refs #19733, Refs #19755, Refs #19779

**What happened?**
Remote same-run retries failed with
`native_remote_recovery_lease_mismatch` and the task was blocked for
reconciliation. The error is thrown by environment acquire, environment
resume, workspace preparation, workspace sync, and remote runner
verification. All of them used the same bare string. The run's `error`
field and its run events did not show which check failed.

**Steps to reproduce**
1. Start reattachment for a remote native run whose saved lease,
workspace reference, or runner identity no longer matches.
2. Read the run's `error`.
3. It shows only `native_remote_recovery_lease_mismatch`.

**Expected behavior**
The error names the step and the field that differed, with no
identifiers, and existing consumers of the code keep working.

## What Changed

- New
`server/src/services/native-runtime/remote-recovery-lease-mismatch.ts`:
the code constant, a closed `stage` and `field` vocabulary, and
`remoteRecoveryLeaseMismatch(stage, field)`. It builds
`native_remote_recovery_lease_mismatch: stage=<stage> field=<field>`.
- `environment-run-orchestrator.ts` (stages `environment_acquire` and
`environment_resume`), `heartbeat/workspace-preparation.ts`
(`workspace_preparation`), `native-workspace-sync.ts`
(`workspace_sync`), and `verifyRemoteRunnerReattachment` in
`native-session-executor.ts` (`runner_verification`) now throw the
detailed form. Each check keeps the same condition and order. Only the
message changes.
- `restart-interrupted-turn.ts` uses the shared constant. It already
matches the code exactly or as the `code: ` prefix, so automatic
continuation after a reattachment loss is unchanged. No other consumer
matches the code.
- `doc/execution-semantics.md` documents the detail format.

## Previous-release state

This change adds no persisted state and changes no saved identity. Runs
that a previous release failed keep the bare
`native_remote_recovery_lease_mismatch` in `error`. Runs failed by this
release store the detailed form. The only consumer (`isReattachmentLoss`
in `restart-interrupted-turn.ts`) accepts both forms, and
`workspace-recovery-retry-copyback.test.ts` covers both.

## Verification

- Exact-detail assertions in the producer tests:
- `server/src/__tests__/environment-run-orchestrator.test.ts`: every
scope, status, expiry, provider, lease-ID, cwd, plugin-task, and resume
case asserts its stage and field. Against the previous producer, 21 of
these cases fail (the message was the bare code). With this change, all
57 tests pass.
- `native-session-executor.test.ts`: a replaced sandbox reports
`runner_verification`/`provider_lease_id`. A missing durable runner
identity reports `identity_run_id` before any sandbox read.
- `native-workspace-sync.test.ts`,
`heartbeat/workspace-preparation.test.ts`,
`native-controller-recovery.integration.test.ts` assert their exact
detail.
- End to end on embedded PostgreSQL:
`heartbeat-native-remote-failure-retention.test.ts` records
`native_remote_recovery_lease_mismatch: stage=environment_resume
field=lease` on the run when the provider no longer resumes the lease,
and it still requests the user's Retry once.
`workspace-recovery-retry-copyback.test.ts` adds a detailed-form row
that still continues once.
- The affected server test files pass locally. `pnpm --filter
@paperclipai/server typecheck` passes.

## Risks

- Low risk. Only the error text changes. Conditions, ordering, and
fail-closed behavior are unchanged.
- Logs and run errors show a longer message. The detail has closed
values only, so it adds no identifiers or secrets.
- A first version of this PR also changed remote retry selection. Review
showed that a plain resume in a new sandbox hits the remote workspace's
unsaved-work hold, and that a `destroy` disposition does not prove the
old sandbox is gone. That change is removed. It needs a separate design.

## Model Used

- Claude Opus 5.5 (Anthropic), model ID `claude-opus-5-5`, run in Claude
Code with tool use (shell, file editing, read-only browser access to
staging).

DottaandClaude Opus 5.5 a4050187ec docs(rules): make upgrade safety part of run and recovery design (#19827)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs save session, checkpoint, lease, and launch state, and
recovery resumes that state later
> - Deploys and restarts often land between the save and the resume, so
one release resumes state that another release saved
> - On 2026-11-06/07, staging deployed four times. Most of 182 failed
runs were saved by one release and resumed by another (#19462, #19659,
#19755)
> - These refusals showed as the generic retryable
`native_session_interrupted`. Retries repeated them, and recovery
replaced a thread (now prevented by #19733). Remote-only code also
shipped without a test that applied Daytona confinement (#19743)
> - This pull request makes upgrade safety a required part of how we
design, fix, and review run and recovery code
> - The benefit is that authors, agents, and Greptile check the release
cutover before a change ships, not after a deploy breaks saved runs

## Linked Issues or Issue Description

Refs #19462, Refs #19516, Refs #19622, Refs #19659, Refs #19733, Refs
#19743, Refs #19755

**Issue type**
Missing contributor guidance for run and recovery code.

**Where is the issue?**
`.agents/skills/fix-failed-paperclip-run/`, `rules/`, `AGENTS.md`, and
`doc/execution-semantics.md`.

**What's wrong?**
No rule or skill step asks how state saved by the previous release is
handled. Fixes added one error code at a time. Saved-identity refusals
used a generic retryable code.

**Suggested fix**
Add a scoped repository rule and additive skill and contract text that
require a previous-release story, permanent named refusal codes, and
cutover tests.

## What Changed

- Add `rules/upgrade-safe-run-state.mdc`. It covers native runtime,
recovery, session preparation, runner, ACPX engine, and sandbox image
paths, and the `packages/db` schema for native run, checkpoint, session,
and run identity state. It requires authors to state how
previous-release state is handled. It requires a permanent, named code
for unknown or changed saved identity, a class-level fix, an
old-saved/new-resumed regression, a deploy-lands-mid-run case where
relevant, and a remote-confinement test for sandbox paths.
- Register the rule in `.greptile/files.json` with the same scope as its
`globs`.
- Link the rule from the "Scoped repository rules" section of
`AGENTS.md`.
- `fix-failed-paperclip-run` skill: step 1 asks if a deploy or restart
separated save from resume, by comparing served revisions. Step 2 asks
this early. Step 4 adds a "Persisted run identity across releases"
safety row and an upgrade-safety paragraph.
- `references/failure-patterns.md`: add "Saved run state meets a
different release".
- `doc/execution-semantics.md`: add §9.4 "Release compatibility of saved
run state".

## Verification

- Docs, skills, and rules only. No product code changes.
- Confirm that each rule glob matches real paths, for example
`server/src/services/native-runtime/`, `server/src/services/recovery/`,
`server/src/services/heartbeat/session-preparation.ts`, and
`packages/adapter-utils/src/acpx-engine/`.
- Confirm that `.greptile/files.json` parses and that its new `scope`
array equals the rule's `globs`.
- `rules/README.md` names no lint check for rules. I did not edit maps,
so `node scripts/check-maps.mjs` does not apply.

## Risks

- Low risk. The change adds guidance only.
- The rule scope includes all of `packages/paperclip-runner/**`.
Greptile can apply the rule to runner docs or UI files. The rule's
exception section says that changes with no persisted shape or identity
need no cutover test.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, with tool use and code
execution in Claude Code.

Retry reviewed chat preparation with the original accepted input.

Bound retries for authorization proof waits that expire before provider

separately. Keep plan confirmation semantics by assigning the interaction
marker only to question answer delivery and legacy question payloads.

Verification: 433 tests across four backend suites, all 17 project-chat

fix. All applicable CI passed and exact-head Greptile Apex scored 5/5.

DottaandPaperclip 27170dca49 fix(workspaces): preserve the read-only capture phase budget (#19803)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Remote workspace saves must preserve the files produced by a
completed turn.
> - When a sandbox disk is full, the existing fallback transfers a
stable source and seals it on the controller.
> - The fallback gives metadata checks and the portable codec the same
two-minute timer.
> - Slow but successful metadata checks can leave the codec only
milliseconds, although normal sandbox capture allows five minutes.
> - This change keeps the metadata budget and gives the local codec the
existing finite capture budget.
> - All source checks, archive checks, ownership checks, and failure
cleanup remain required.

## Linked Issues or Issue Description

Refs #19465. Related: #19364 and #19619. The open diagnostic change in
#19619 records fallback causes; it does not separate these phase
budgets. No duplicate budget fix was found.

**What happened?**

A retained workspace failed five read-only exports at `stage=archive`
with `transport_timeout`; four warnings also named `ABORT_ERR`. The
fallback had already transferred the source and passed the received-tree
and source inventory checks. Its controller codec received the same
two-minute signal used by those checks.

**Expected behavior**

Metadata checks share a finite two-minute budget. Sealing uses the same
finite five-minute policy as normal sandbox capture. The final source
check uses only the unused metadata budget. A changed source, expired
budget, or cancelled codec must not produce a preservation receipt.

**Steps to reproduce**

1. Create a standalone Git fixture with staged changes, an untracked
result, and a confined symlink.
2. Make the initial sandbox helper report the exact disk-full error.
3. Transfer real files and run the actual inventory scripts. Delay a
successful second inventory reply until just before the native
two-minute deadline.
4. Observe that the real portable codec starts with a live signal, then
aborts when that shared timer expires.

## What Changed

- Name and reuse the existing 300-second command policy for controller
capture.
- Retain the aggregate 120-second metadata budget. Preserve its unused
remainder for the final source recheck.
- Keep the exact disk-full error, source comparisons, file/Git checks,
and cleanup behavior.
- Add six real-filesystem and real-codec controls. Document the separate
phase limits and the current absence of a caller abort signal on the
save interface.
- Repair the existing onboarding test's fake-environment mapping with
the same real-agent PATCH mapping used by its sibling. Verify the
persisted agent through a real GET. Production UI code is unchanged.

## Verification

- Native-timer RED on base `35d41f11bb`: a successful source reply
arrived at 119,981.62 ms. Its command took 119,854.47 ms within its
119,873 ms cap. The actual codec started at 119,982.70 ms with a live
signal and aborted at 120,001.84 ms. Its nested cause matched the
retained warning: `stage=archive reason=operation_failed
transport=transport_timeout code=ABORT_ERR`. The source inventory was
unchanged and private staging was removed.
- The real-archive control sealed 10,166,395 bytes and 533 entries in
555.55 ms. It restored HEAD, staged data, untracked data, and the
symlink, and passed Git fsck. The recorded delay is synthetic; it is not
a measurement of the failed hosted workspace or provider throughput.
- The native RED leaves about 18 ms for the final check too. The
repaired code must still refuse that exact exhausted-metadata case; it
is not claimed as a native-clock GREEN.
- The committed fast regressions control phase time and delegate to the
actual inventory commands and portable codec. They cover successful
restore after the old metadata signal expires during sealing,
pre-capture metadata expiry, codec deadline/cancellation, and final
metadata expiry after a real completed archive.
- From `server/`: `node ../node_modules/vitest/vitest.mjs run
src/services/remote-workspace-readonly-capture-budget.test.ts
src/services/remote-workspace-transport.test.ts
src/services/remote-workspace-readonly-inventory.test.ts
src/services/remote-workspace-transfer-timeout.test.ts --fsModuleCache`
— 156 tests passed in 42.30 seconds before removal of a redundant test
duration assertion. The final-head six-case regression also passes after
rebasing onto `fff70fe49e`; only unrelated Runner and E2E files changed
in that rebase.
- Review follow-up `ad565dd984` makes the phase clock fully controlled.
It checks the requested final 2,000 ms budget separately from the real
subprocess's 30-second test limit. All six controls pass in 11.94
seconds, and server TypeScript passes again. The earlier
real-time-plus-offset clock could falsely fail on a loaded machine; that
review finding is fixed.
- Server TypeScript and module boundary checks pass. The first
TypeScript attempt could not resolve the unbuilt plugin SDK. Building
that existing workspace prerequisite resolved the setup errors; no
source workaround was added.
- The first preflight attempt used the host pnpm shim and was stopped.
The second lacked sandbox network access and was stopped. The canonical
cached preflight then completed in 22.1 seconds with the Runner build
restored from cache. A later test launch used the wrong working
directory for a test rewrite; its wrapper was stopped before waiting
through a second native-timer test. None of these interrupted attempts
is a pass.
- Final-head CI first failed one unchanged Runner-support privacy test
at 30 seconds: [job
failure](https://github.com/paperclipai/paperclip/actions/runs/42359560195/job/128365192635).
The other 6,864 tests passed and four were skipped. The failing test and
its report owners match base `fff70fe49e`; the exact case passes locally
unchanged in 2.97 seconds (one pass, 40 unselected). Job cleanup
reported an orphan `unzip`; that does not establish the timeout cause.
GitHub rejected the scoped retry while the parent workflow was still
running, so no retry has started. No old-head retry was started because
the separately proven onboarding fixture repair requires a new head and
a fresh full pipeline. The original Runner failure remains recorded.
- The same CI run failed onboarding case 160 at 60 seconds; its retained
page showed `Environment not found`. The fixture injected an environment
only in browser responses, then sent that fake ID to the real agent
update. The original case passed locally in 37.44 seconds despite
rejected HTTP 422 updates. Adding a real update-success guard produced a
local RED in 26.83 seconds (expected 200, got 422). Reusing the sibling
fixture's fake-ID-to-local-default PATCH mapping produced GREEN in 22.52
seconds. A real GET verifies the same persisted agent ID, name, and
default environment. Existing sign-in, cancellation, and no-hire
assertions are unchanged. CI screenshot/error context and the local
persistence RED remain retained.
- All other product checks on `ad565dd984` passed, including build,
TypeScript, all general and serialized server shards, and native Runner
checks. Final head `58bb4ee2411dfefca462f0e9b5a701d84ce1326e` passes the
fresh pipeline: [CI
run](https://github.com/paperclipai/paperclip/actions/runs/42360927780).
Runner support passes in 3m36s and onboarding shard 5/8 passes in 5m46s,
with no Runner-support source change. The original failures remain part
of this verification history.
- Environment: macOS arm64, Node 26.4.0, real Node/Git/filesystem
operations. No provider or recovery calls, replayed turn, source
mutation, or hosted recovery acceptance was performed. Final-head
required CI and review pass; the exact gate state is recorded below.

- Exact-head final gate: 57 successful checks, three skipped, two
neutral, and no failures. Both required gates (`ci / verify` and `ci /
e2e`) pass. Greptile reviewed this exact head at 5/5, and zero review
threads remain open. The non-required companion `review` job is still
queued with no steps; it has not passed, and GitHub therefore reports
`UNSTABLE` while the PR remains mergeable.

## Risks

- Controller work after transfer can now take up to two minutes for
metadata plus five minutes for sealing. Each phase remains bounded.
Existing entry, repository, configuration, and transfer limits stay in
force.
- The save interface has no caller abort signal. This change adds no
Stop guarantee and does not replace the recovery retry window with an
operation deadline. Existing physical ownership and publication fences
remain in force.
- This proves the timer mechanism with a synthetic slow inventory. It
does not measure the actual dirty workspace size or show that its
archive finishes within five minutes. A guarded file-only recovery and
independent durable readback remain required after normal delivery.
- The onboarding fixture maps only its exact synthetic environment ID.
It still calls the real agent update and read routes. It does not loosen
production environment validation.
- No schema, provider transport, task status, recovery policy, or source
cleanup authority changes.

## Model Used

OpenAI GPT-6 family through Codex, with reasoning, repository tools,
code execution, and regression tests. The exact serving model ID and
context window are not exposed in this session.

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - After a control-plane restart loses a turn, the native runtime sends
a same-conversation continuation (#19501, #19699, #19771)
> - A restart can also kill shell or background processes that earlier
turns started

its killed `bench.sh` and set the task to blocked
> - The continuation prompt told the agent not to "blindly rerun an
action whose outcome is unknown", so the agent did not re-run the
command
> - This pull request tells the agent that earlier processes may be
gone, and to check the workspace outputs and re-run a command whose
expected output is missing
> - The benefit is that a task can finish after a restart instead of
blocking on a process that no longer exists

## Linked Issues or Issue Description

Refs #19501, #19699, #19771

**What happened?**

Restart chaos workload B5 (Codex and Claude) failed this way three
times: storm 6b t14, s7111 t16 and storm 10 t12. The agent started
`bench.sh` in the background. A restart killed it. The restart
continuation agent tried to find its tool session and got "process
inspection is denied". It then blocked the task. The comment read:
"Blocked by the Paperclip runtime restart: the benchmark session is
unavailable…". It added that it "cannot verify whether the original run
is still active or recover its output, so I have not rerun it".

**Expected behavior**

The agent knows it is in a resumed session after a restart. It checks
the workspace for the command's outputs. If the expected output is
missing, it re-runs the command and finishes the task.

**Root cause**

`packages/paperclip-runner/src/native-session-runtime.ts`,
`restartContinuation`: the prompt did not say that processes from
earlier turns may be gone. It told the agent to inspect each unfinished
command's "current state" and not to "blindly rerun an action whose
outcome is unknown". With the process gone, the agent could not inspect
it, so it blocked.

## What Changed

- The restart continuation prompt now says:
  - This is a resumed session after a Paperclip control-plane restart.
- Shell commands and background processes from earlier turns may no
longer be running, and their tool sessions may be gone. Do not block
only because one cannot be found or inspected.
- Check the workspace for the outputs or artifacts the command should
have produced. If the expected output is present, use it. If the
expected output is missing, re-run the command.
- Do not repeat completed work. Before repeating an action with external
effects (a push, a message, a deployment), check whether it already took
effect. If you cannot tell, report the blocker.
- The prompt does not say that re-running is always safe. Process
teardown (#19727) has not merged.
- `doc/execution-semantics.md`: one additive sentence.

## Verification

- `native-session-runtime.test.ts`: the three restart continuation tests
(Codex, ACPX, OpenCode) now check the new guidance. They were red before
the prompt change and are green after it.
- Guard: "uses the admitted session cwd in the task envelope" now checks
that fresh turns and ordinary resumed turns do not contain the restart
guidance.
- `npx vitest run src/native-session-runtime.test.ts src/drivers/codex/
src/live/runnerd-restart-continuation.test.ts` in
`packages/paperclip-runner`: 603 passed.
- `tsc -p tsconfig.json` and `tsc -p tsconfig.test.json` for
`packages/paperclip-runner` are clean.
- Not run: a live restart-chaos replay with a real model.

## Risks

- Low. This changes only the prompt text of the restart continuation.
Ordinary turns do not change.
- An agent may now re-run a command whose earlier run had partial side
effects. The prompt asks it to check external effects first, and to
re-run only when the expected output is missing.

DottaandClaude Opus 5.5 ef83d566ca fix(native): ask for the result once after a restart continuation ends without one (#19771)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs continue a turn that a control-plane restart lost, in
the same conversation (#19501, #19699)
> - In restart storms 5, 6b and 8, ACPX Claude runs crossed restarts,
ran the continuation, and then failed with
`native_session_retry_exhausted`
> - The continuation completed, but Claude ended it with "I'll wait for
the notification when it completes" for a background command, and did
not call `paperclip_finish`
> - The next same-run attempt then sent no turn at all and failed with
"session returned no semantic result"
> - This pull request makes the continuation ask for the result, and
asks once more in the same attempt if the continuation still ends
without one
> - The benefit is that a restart-interrupted task settles without a
Retry, and the restarts that the run survived cannot block the request

Refs #19501, #19699, #19720

**What happened?**

Storm 8, run 84c532f7 and its Retry 0faead66 (ACPX Claude, task CHA-5).
The steps are the same in both runs:

1. `resume_dead_runner`, then `session.resumed`, then `turn.failed` with
`provider_turn_lost_on_restore` (recoverable).
2. The restart continuation runs. Claude starts the bench in the
background and ends the turn with "I'll wait for the notification when
it completes". The turn completes with no `paperclip_finish`.
3. Lifecycle: "provider turn completed without a semantic result;
same-run disposition recovery persisted" (attempt 2).
4. 30 s later, attempt 3 restores the session. It sends no turn. After
about 2 s it fails with `native_finalization_missing: session returned
no semantic result`, and the attempt count makes it
`native_session_retry_exhausted`.

**Expected behavior**

The continuation tells the agent to finish and report its result. If the
continuation still completes without a result, Paperclip asks for the
disposition one time. Restarts that the run already survived do not
block that request. An agent that never reports a result still fails
closed.

**Root cause**

- `packages/paperclip-runner/src/drivers/codex/codex-harness-session.ts`
`startTurn` (lines 224 and 248): the restart continuation uses the
driver's one-shot disposition marker
(`dispositionOnlyRecoveryAvailable`). #19699 uses the marker on purpose,
so that a crash can adopt the accepted continuation turn. The marker
then stays consumed with the continuation turn id.
-
`packages/paperclip-runner/src/drivers/codex/codex-session-terminal.ts`
(line 226): only a *lost* continuation gives the marker back. A
*completed* continuation with no result does not.
- `packages/paperclip-runner/src/native-session-runtime.ts`
(`dispositionRecoveryWasSubmitted`, about line 2761): on the next
attempt, the consumed marker looks like a disposition request that
already ran. Recovery replays the continuation's terminal and starts no
turn. So the disposition request never happens.
- `server/src/services/native-runtime/native-session-executor.ts` (lines
9755-9761 and `nativeSessionFailureDisposition` at 7768): the
`semantic_result_missing` same-run retry charges a provider attempt on
the same counter as restart resumes. In this run, attempt 3 was the last
allowed attempt.
- The continuation prompt (`restartContinuation`) did not tell the agent
to report a result, or not to stop and wait for a background
notification.

## What Changed

- Codex-protocol driver (used by Codex and by ACPX through runnerd):
when a restart continuation completes without a semantic result, the
driver gives back the one-shot disposition marker. The disposition
request is not a continuation, so it consumes the marker for good.
- Native session runtime: after that, the same attempt sends one
disposition request (`Paperclip semantic-result recovery after a restart
continuation ... invoke exactly one paperclip_finish or
paperclip_block`). It does this only when the driver shows that the
continuation borrowed the marker and gave it back. Other drivers keep
the current behavior.
- Restart continuation prompt: it now says to finish in this turn, not
to end the turn to wait for a background command or a notification, and
to report one `paperclip_finish` or `paperclip_block`.
- `doc/execution-semantics.md`: one additive paragraph.
- No server change. The disposition request runs in the same attempt, so
it uses no provider attempt. This avoids `native-restart-recovery.ts`
(#19747).

## Verification

Red before the fix, green after:

- `codex-app-server-driver.recovery.test.ts` "keeps one disposition
request after a restart continuation completes without a result". Red:
marker stays consumed on `turn-2`. Green: the marker is given back, one
disposition turn starts, and a resultless disposition turn does not
re-arm.
- `native-session-runtime.test.ts` "settles a restart continuation that
ended without a result through one disposition turn (Codex driver)".
Real Codex-protocol driver with a fake transport. Red: only one
`turn/start`, then `native_finalization_missing`. Green: the disposition
turn `turn-3` reports the result and the run completes.
- `native-session-runtime.test.ts` "asks once for the disposition when a
restart continuation ends without a result" and "fails closed when the
driver keeps the continuation's disposition marker".

Also run:

- `npx vitest run src/native-session-runtime.test.ts src/drivers/codex/`
in `packages/paperclip-runner`: 593 passed.
- `src/live/runnerd-restart-continuation.test.ts` (real runnerd and fake
Codex, killed runner): 5 passed.
- `tsc --noEmit` for `packages/paperclip-runner`.
- `pnpm verify` exits 2 because the doc change is a global CI input.
Required CI supplies the broad coverage.

Not run: a live replay of storm 8 t05 with Claude. The chaos harness
needs provider keys from the operator's shell.

## Risks

- Low to medium. A run whose continuation ends without a result now gets
one more provider turn in the same attempt. The bound is one disposition
request per continuation. Each continuation still needs an admitted
restart, and the provider-attempt budget bounds those.
- If the controller crashes after the continuation completes but before
its checkpoint, the checkpoint keeps the stricter consumed marker. That
case fails closed as before.
- The prompt text changes for restart continuations. It does not change
a protocol schema or a profile digest.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, through Claude Code
with tool use (shell, file edits, code execution).

DottaandClaude Opus 5.5 7475577cdb fix(daytona): keep a runner sandbox alive through the controller reconnect grace (#19754)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A remote agent run executes in a Daytona sandbox and keeps working
while the Paperclip server restarts
> - The server reattaches that runner within a 7-minute reconnect grace
> - Daytona stops an idle sandbox after its `autoStopInterval`, and it
counts only SDK and lifecycle calls as activity
> - With the server down, nothing touches the sandbox, so a 5-minute
auto-stop kills the runner before the server returns
> - This pull request makes the host tell the provider its reconnect
grace, so Daytona never auto-stops a runner sandbox inside that grace
> - The benefit is that a controller outage of up to 7 minutes no longer
turns a healthy remote run into a blocked task

## Linked Issues or Issue Description

Refs #19199 (the same floor for the warm runner idle window). Refs
#19741 (follow-up delivery through restarts; no overlap).

**What happened?**
A restart-chaos wave on Daytona killed the server for 4m51s while a
per-turn remote run was active. The environment used `autoStopInterval:
5`. The last sandbox activity was at 06:09:16. The server came back at
06:14:19 and then crashed again. At 06:15:21 recovery called the
sandbox. The plugin found it not started and started it again. The
runner identity marker was still on disk, but its process was gone:
`native.remote_runner_recovery_failed {stage: process_verification,
reason: process_not_running}`, then
`runner_remote_process_identity_unavailable`. The task went from done to
blocked. An earlier wave showed the same failure after a 4m45s outage.

**Expected behavior**
A sandbox that holds a live remote runner survives any controller outage
up to the reconnect grace. The server reattaches the runner and the run
continues.

**Steps to reproduce**
1. Create a Daytona environment with `autoStopInterval: 5` and a
`paperclip_runner` agent.
2. Start a remote run and kill the server for more than 5 minutes (less
than 7).
3. Restart the server. Recovery reports `process_not_running` and the
task becomes blocked.

## What Changed

- `server`: add `resolveRunnerReconnectGraceMsForRun`. It returns
`REMOTE_RUNNER_RECONNECT_GRACE_MS` for `paperclip_runner` on a sandbox
environment.
- `server`: forward `runnerReconnectGraceMs` to the provider worker on
lease acquisition and on the recovery reattach resume. It uses the same
provider-only path as `warmRunnerIdleTimeoutMs`. It is not lease
identity, lease metadata, or saved environment config.
- Daytona plugin: the effective auto-stop is at least the largest host
floor (warm idle window or reconnect grace) plus 5 minutes. With the
current grace this is 12 minutes. The plugin applies it at creation and
raises an older sandbox's shorter interval on resume (bounded, best
effort).
- Daytona plugin: keep the forwarded grace out of the normalized config.
Update the `autoStopInterval` manifest description.
- `doc/execution-semantics.md`: document the reconnect-grace floor next
to the warm floor.

## Verification

- Red/green Daytona plugin tests: `cd
packages/plugins/sandbox-providers/daytona && npx vitest run --config
vitest.config.ts`. The new cases failed before the fix (for example
`expected 120000 to be >= 720000`, and no `setAutostopInterval` call on
resume). All 605 tests pass after the fix.
- Server tests: `cd server && npx vitest run
src/__tests__/environment-run-orchestrator.test.ts
src/__tests__/environment-runtime.test.ts`. 247 pass. They prove
acquisition forwards the grace only for `paperclip_runner` on a sandbox,
that the reattach resume forwards it, and that it does not reach lease
metadata or saved config.
- `pnpm typecheck` for the plugin and `tsc --noEmit` for the server are
clean.
- `pnpm verify` asks for broad CI coverage because a doc changed.
Required CI supplies it.
- Evidence from the kept wave database: lease metadata shows
`autoStopInterval: 5`, `reuseLease: false`, `runnerLifecycleMode:
per_turn`. The run had no events between 06:09:16 and 06:14:19.

## Risks

- Cost: a runner sandbox that leaks (no cleanup) now auto-stops after 12
minutes instead of a shorter configured value. Cleanup still stops or
destroys released sandboxes. Explicit `0` and longer values are
unchanged. Auto-archive and auto-delete are unchanged.
- I did not inspect the sandbox state in Daytona directly. Cleanup
destroyed it before this investigation. The proof is the timing, the
lease config, and the `process_not_running` result after a restart that
kept the disk.
- No live Daytona replay ran.

DottaandClaude Opus 5.5 3895195f4b fix(native): report a retained provider pack the controller does not ship as incompatible (#19755)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Remote OpenCode runs stage a controller-owned provider pack into the
sandbox before the provider starts
> - Since #19558, an ordinary OpenCode continuation retains the pack
that an earlier release admitted for its saved provider session
> - After a controller release changes the pack, the controller no
longer ships those bytes, and the continuation must stay blocked
> - The configured-pack upload path did not detect that case: it read
the build-time archive receipt for the old digest and failed with
`runner_remote_provider_archive_invalid`, a generic, retryable error
that suggests corrupt image files
> - This pull request compares the configured pack's identity with the
selected identity before any upload and fails as
`runner_remote_provider_artifact_incompatible`
> - It also puts a fixed reason in each real archive integrity error
> - The benefit is a correct, permanent classification that matches the
bundled-image path, no wasted retries, and a diagnosable message for
real archive corruption

## Linked Issues or Issue Description

Refs #19558, #19743

**What happened?**

On a hosted deployment, two remote OpenCode runs of a review agent
failed before the provider process started. The error was
`runner_remote_provider_archive_invalid` (classified as a generic
`native_session_interrupted`). Both runs continued an issue whose
provider session was admitted by an earlier release. In both runs, the
run log shows `provider_pack.compatibility`, `provider_pack.verify`, and
`provider_pack.verify_preinstalled` fail, then
`provider_pack.archive.verify` fails after 4–6 ms. Fresh runs of the
same agent on the same controller passed pack preparation with the
current pack.

The cause is not a cache race. The archives are created at image build
time (`Dockerfile` `runner-provider-pack` stage) and the server never
rewrites them. The retained authority selects the old pack digest.
`readProviderPackLayers` then compares the receipt's
`providerPackDigest` (current release) with that old digest and throws
`runner_remote_provider_archive_invalid`. Directory staging (no archive)
instead clears the staged remote pack, uploads the different pack, and
fails only at the final verification.

**Expected behavior**

A continuation pinned to a pack that the controller does not ship fails
as `runner_remote_provider_artifact_incompatible`, as the bundled-image
path already does ("the image provider pack did not match the bundled
release identity"). It does not clear or upload anything. Real archive
corruption keeps `runner_remote_provider_archive_invalid` with a fixed
reason that the run report shows.

**Steps to reproduce**

1. Build a provider pack and its archives for digest A.
2. Call `uploadVerifiedProviderPack` with that pack and a selected
(retained) digest B.
3. Before this change: the call fails with
`runner_remote_provider_archive_invalid` (v1 and v2 archives), or
resolves after it clears and re-uploads the remote pack (directory
source).

## What Changed

- `uploadVerifiedProviderPack` takes the configured pack's
`sourceDigest`. If it is not the selected `expectedDigest`, the call
fails with `runner_remote_provider_artifact_incompatible: selected
provider pack <12 hex> is not the controller's pack <12 hex>; ...`. The
check runs before the remote clear, the archive read, the directory hash
and any upload.
- The executor passes the configured pack's identity
(`readRemoteProviderPackIdentity(root, false)`, the same reader that
selects the current pack).
- Archive integrity errors keep the
`runner_remote_provider_archive_invalid` prefix and add a fixed reason:
`receipt_unreadable`, `receipt_identity_mismatch`, `receipt_invalid`,
`layer_invalid`, `layers_unreadable`, `archive_unreadable`,
`archive_not_file`, `size_mismatch` or `sha256_mismatch`. The run report
keeps only the outer message, so the reason must be in the message.
Filesystem causes stay on `cause` and do not put private paths in the
message.
- The v1 reader now uses the shared `verifyArchive` helper.
- `doc/execution-semantics.md` documents the rule.

## Verification

- Red before the fix (production files unchanged, new tests only): `npx
vitest run src/services/native-runtime/provider-pack-archive.test.ts`
gave 5 failed / 38 passed. The v1 and v2 cases failed with exactly
`runner_remote_provider_archive_invalid`, which is the hosted error. The
directory case resolved after it cleared and uploaded the remote pack.
The reason tests got a bare `runner_remote_provider_archive_invalid`.
- Green after the fix: the same file gave 43 passed.
- `npx vitest run
src/services/native-runtime/native-session-executor.test.ts`: 1245
passed. This includes the #19558 continuation cases.
- `remote-provider-pack`, `remote-provider-pack-authority` and
`remote-provider-pack-verification` tests: 69 passed.
- `pnpm --filter @paperclipai/server typecheck`: all layers passed.
- Review follow-up (`c8156841a9`): an unreadable numbered layer now
reports `archive_unreadable`. The layered-corruption test deletes
`0.tar.zst` and checks for that reason before any transfer. The archive
file gave 43 passed.
- Hosted evidence came from read-only run, event and issue-run reads
only. No hosted retries, recovery or deploys.

## Risks

- This change does not unblock an affected session. It makes the failure
honest and permanent: `runner_remote_provider_artifact_incompatible` is
already a permanent, pre-session failure code, so the run is not retried
with the same result. To recover, the session needs its original
artifacts (the captured provider-artifact path, which #19743 repairs for
new admissions) or an authorized continuity break.
- Low risk for other paths. Fresh launches select the configured pack's
own identity, so the digests are equal. Restored provider artifacts and
compatible installed packs return before this upload path.
- Callers that match `runner_remote_provider_archive_invalid` with a
substring still match. No code compares the exact message.
- Not tested end to end against a hosted sandbox. The executor-level
wiring of `sourceDigest` has typecheck coverage but no dedicated
executor test.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic. Agentic tool use with
shell, code editing, test execution and read-only authenticated browser
diagnostics.

DottaandClaude Opus 5.5 6d112c74cf fix(native): do not charge a restart resume that never started the provider (#19747)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs have an execution recovery budget of three provider
attempts, so a run that keeps failing stops retrying
> - #19720 stopped charging a crash restart when the previous restart
resume made progress
> - In a crash loop (several kills within seconds), the controller can
die again before the resumed execution starts its runner
> - The next claim then charged that resume, although it used no
provider work
> - This pull request does not charge a resume that never started; the
next claim replaces it
> - The benefit is that fast restart bursts do not exhaust a healthy
run's budget, and the generation cap still bounds real loops

## Linked Issues or Issue Description

Refs #19720, #19625

**What happened?**
In a restart-chaos storm wave, 8 runs still reached
`execution_recovery_budget_exhausted`, mostly in K6 crash loops (three
kills in about 20 seconds). Example: a Codex run was claimed at
generation 9, attempt 3. The controller was killed 6 seconds later,
before the executor recorded `native.process_start_requested`. The next
claim found no progress after generation 9's position, charged, and
blocked the run at attempt 3. The recorded history of the blocked runs
shows that almost every charge after the first restart was for a resume
with no start evidence (no runner request and no runner event) before
the next claim. Two runs were blocked at generation 12, the existing
cap.

**Expected behavior**
A resume that never started the provider consumed nothing and must not
be charged. A resume that started and then made no progress must still
be charged. The generation-12 cap stays.

**Steps to reproduce**
Start a native run. Kill the server during the run. Let a restart resume
do work. Then kill the server repeatedly within seconds, before each new
controller starts the runner. After one or two such bursts the run is
blocked with `execution_recovery_budget_exhausted`.

## What Changed

- `native-restart-recovery.ts`: `restartResumeKeepsAttempt()` replaces
`previousResumeMadeProgress()`. It reads the previous claim's recorded
`progressWatermarkSeq` and `progressAttempt`
(`lastRecoveryClaimResume()`).
- New `nativeExecutionStartedSince()`: after the watermark, it looks for
`native.process_start_requested`, `native.process_identity_recorded`,
`adapter.invoke`, `tool.execution.started`, or any event with a runner
`source_event_id`. This is the same start evidence as
`hasNativeExecutionStartEvidence()`, limited to events after the
watermark.
- When the previous resume never started, the claim keeps the attempt if
the run is already at the attempt that resume was to run as. If the
executor never applied that charge (killed before its execution lease),
the claim charges once, so the run reaches that attempt and never goes
above it.
- When the previous resume started, the #19720 progress rule applies
unchanged.
- The generation-12 cap applies to both rules.
- `doc/execution-semantics.md` states the rule.

## Verification

New tests in
`server/src/services/native-runtime/native-runner-restart-recovery.integration.test.ts`
(embedded Postgres, real `claimNativeRestartRecoveries`):

- `does not charge for a resume killed before it started the provider
(after the executor took its lease)`: one progress resume, then four
crash claims with no start evidence. The attempt stays 2. A resume that
starts and fails then charges to 3. Red on master (charged to 3, then
blocked).
- `... (before the executor took its lease)`: the same with the lease
never taken. Green on master and with the fix, as a guard.
- `charges the owed attempt once when an unstarted first resume is
replaced`: the replacement claim charges once (attempt 2).
- `bounds a crash loop that never starts the provider`: blocks after the
generation cap. Red on master (blocked at the third claim).
- The #19720 tests now record `native.process_start_requested` in their
resumes, as a real resume does.
- `native-runner-restart-recovery.integration.test.ts`,
`heartbeat-native-restart-suspension.test.ts`,
`native-restart-recovery-isolation.test.ts`,
`native-remote-retry-admission.test.ts`: 231 passed, 14 skipped.
- `tsc --noEmit` for `server` has no errors in the changed files.

## Risks

- A crash that happens before the runner start, every time, gets free
resumes until generation 12. Then the budget applies. This is the same
bound as the progress rule.
- Start evidence is the executor's durable
`native.process_start_requested` record, written before any backend may
spawn a runner. If an older path launched a provider without it, that
resume would be treated as unstarted until the generation cap.

c3180398fa fix(native): resume a remote Runner after a settled suspension
fix(native): resume a remote Runner after a settled suspension

A scheduled checkpoint retry can retain a remote reattach claim after
closing its failed predecessor cleanly suspends and exits the Runner.
Resume only that exact settled source after confirmed exit and a fresh
identity/state check. Preserve pending work and uncertain-exit fences.

Admit the last already-charged provider attempt and share one bounded
recovery deadline with the final state read, retaining closed diagnostic
labels on read failures. Cover fresh ACPX Runner relaunch on attempts
two and three through actual processes and the durable close barrier.

Six affected suites pass 1,579 tests, with 14 environment-gated skips;
all server typecheck layers pass on Node 25.6.1. The complete provider
turn continuation failure remains preserved as follow-up #19751.

DottaandClaude Opus 5.5 e620ce3678 fix(heartbeat): deliver each accepted follow-up exactly once through restarts and admission holds (#19741)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A user can comment, click Retry, or rely on automatic recovery while
an agent works on a task
> - Restart-chaos waves showed accepted follow-ups being dropped, or
delivered twice, around restarts and temporary company admission holds
(accounting still settling after a restart)
> - A dropped comment means the user's request is never acted on. A
duplicate reopens work that is already done
> - This pull request makes accepted work wait through a temporary hold
and resume when it clears. It also stops a comment from being promoted
again after a completed run already received it
> - The benefit is that each accepted follow-up is delivered exactly
once, eventually, unless the task is cancelled or a reached hard stop
applies

## Linked Issues or Issue Description

Refs #19702 (never-started tasks during a temporary hold), #19700
(bounded accounting hold), #14910 (stale reopen from a deferred wake; no
file overlap).

**What happened?**
Restart-chaos waves found these shapes:
1. **Comment wake cancelled.** A comment was saved behind a run and
promoted when the run ended. A temporary company hold refused the
unstarted queued run, and claim cancelled it terminally. The recovery
wake that followed was cancelled the same way, and the task rested
`blocked` without the comment.
2. **Dead Retry.** A Retry click during the hold stayed
`deferred_issue_execution` after the hold cleared. Nothing woke it, and
the issue held no execution lock.
3. **Refused assignment.** A new task's first wake was refused during
the hold. Nothing woke stranded-work recovery when the hold cleared, so
the task stayed `todo` with no run.
4. **Silent comment after recovery.** A comment was saved behind a run
that restart recovery finalized. A company-scoped hint waited out the 30
s deferred-receipt rescan, so the task looked done with the message
unread.
5. **Comment delivered twice.** A run whose provider process was lost
had a saved comment. Its retry started after the comment, received it in
its prompt (task history), did the work, and finished the task. The
saved wake was then promoted anyway, which reopened the done task.

**Expected behavior**
An accepted follow-up (comment, Retry, recovery) is delivered exactly
once, eventually, unless the task is cancelled. A temporary refusal
never ends in a terminal cancel, skip, or block. Reaching a hard stop
remains the board's decision.

## What Changed

- `heartbeat/queue.ts`: on a budget block at claim, an unstarted queued
run stays queued when the block is temporary. A reached hard stop or
blocked unpriced usage still cancels it.
- `recovery/service.ts`: stranded-work recovery waits out a temporary
hold for any task. It does not escalate to `blocked`. This extends
#19702 beyond never-started tasks.
- `budget-block-ownership.ts`: a shared `isBoardOwnedBudgetBlock`, moved
out of the recovery service. `budgets.ts` is unchanged.
- `run-cost-accounting.ts`: settling a run's accounting wakes queued-run
dispatch, the deferred-receipt worker, and stranded-work recovery. Held
work waits passively; this is what resumes it.
- `deferred-execution-notifications.ts`: new
`notifyDeferredWakesForIssue`. `native-run-projection.ts` (a run
reaching a terminal status) and `environments.ts` (lease release) now
hint each saved wake of the issue by id, so delivery does not wait out
the company rescan interval.
- `wake-queue/adapters/postgres.ts`: release treats a saved comment as
delivered only when a succeeded run of the wake's agent on that issue
started after the comment's latest revision, and either received the
comment as its own wake input (`wakeCommentIds`) or was a retry of the
interrupted turn whose task history included it. In that case it cancels
the saved wake with "Queued messages were already delivered to a
completed run" and leaves the task as it is. Task history alone never
consumes a message saved for its own turn. One query checks the whole
batch.
- `run-cost-accounting.ts`: settling late receipt debt also sends the
hold-release notifications.
- `doc/execution-semantics.md`: documents the rule.

## Verification

Red on `master` and green with this change, on embedded Postgres:
- `server/src/__tests__/heartbeat-held-comment-wake.test.ts`:
- A promoted comment refused by the hold stays pending, with no
cancelled run and no `blocked` task. It is delivered once after the hold
clears through real `accountRunCost`.
- A Retry clicked during the hold starts exactly once after accounting
settles, which wakes its owner.
- A new task whose assignment was refused during the hold starts once
accounting settles, which wakes stranded-work recovery.
- A comment that a later succeeded retry already received as history, or
that a later run received as wake input, is consumed without reopening
the task.
- Guard tests (green on both):
- A comment is still delivered in each of these cases: the later run
never received it, it was edited after that run started, it was posted
while the run was already running, or a non-retry run only saw it as
history.
  - A task whose continuation was refused waits out the hold.
  - A reached hard stop is still refused.
- `server/src/__tests__/native-run-projection-work.test.ts`: projecting
a recovered run terminal hints the saved comment's own wake (red on
`master`).
- Related suites pass locally (14 files, 482 tests): wake-queue, queued
comments routes, refused assignment wake, native run projection.
- Live replays (local, unmasked, kept instances):
- `--replay w-20261107T031005-s7501/t04` (Claude C1, K1): PASS. The
comment's run was created at 03:56:24 during the hold, stayed queued,
started at 04:06:24 when the hold cleared, and succeeded. It is the only
run carrying the comment.
- `--replay w-20261107T002911-s7401/t01` (before the per-wake hint): it
reproduced shape 4. Run 592d772f was killed 250 ms after
`run.result.accepted`, released and finalized at restart, and the task
rested `done` with the comment still saved. Calling the existing sweep
on the kept database promoted it, which confirmed that the missing piece
was the trigger.

## Risks

- A queued run can now sit queued for the length of a temporary hold,
which #19700 bounds. It does not hold the issue's execution lock, so
later comments still coalesce into it.
- The delivered-comment rule depends on the run's recorded prompt
context. A succeeded run that received the comment in its history counts
as delivery, even if the agent did not act on it. This matches
exactly-once delivery semantics.
- Settling accounting now emits three extra notifications per run. They
are coalesced per company.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, run as an agent in
Claude Code with tool use (shell, file editing, local test execution,

DottaandPaperclip 18b6b71d83 fix(native): refresh per-turn projections from the selected checkpoint (#19744)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Per-turn native sessions save controller checkpoints and suspended
Runner backups under separate owners.
> - A local controller projection can still name the first turn after
the next turn has saved its checkpoint and backup.
> - The old per-turn restore path selected that stale local reference
instead of the newer canonical source.
> - Admission then saw different turn identities and archived the valid
backup with the old projection.
> - This change uses the canonical selected checkpoint and the existing
finished-owner proof before it replaces a stale projection.
> - The benefit is that a third turn keeps the valid saved conversation
and backup.

## Linked Issues or Issue Description

**What happened?**

After two successful per-turn remote runs, a third turn could fail
before provider execution with unavailable provider resume state. The
selected database checkpoint and suspended backup belonged to the second
run. The local controller projection still belonged to the first run.

**Expected behavior**

The selected checkpoint must govern controller rehydration. Preserve the
older projection and the selected run's backup. Do not overwrite
current, newer, foreign, changed or unsettled ownership evidence.

**Steps to reproduce**

1. Save two real controller checkpoints for one per-turn conversation
and finish both owners.
2. Leave the first checkpoint's readable projection or external marker
beside the second run's suspended backup.
3. Admit the third run through the real canonical selector and backend
owner.
4. Before this change, admission archives the active backup with the
stale projection and leaves no active controller state.

Related: #18018 added per-turn controller restoration. #18718 refreshed
warm projections. #18846 added finished-owner retirement. This change
keeps the selected per-turn source from entering that retirement path
because of an older projection. The open warm-only change #18436
concerns a different restart branch.

## What Changed

- Resolve the canonical source before refreshing a prior per-turn
controller projection.
- Re-read it under the existing sorted coordinator locks. Replacing an
older owner reuses finished-owner checks for both runs and verifies
their full session scope. A same-source marker only rehydrates its exact
selected identity before the normal retained-sandbox verification.
- Recheck the exact initial local bytes after asynchronous reads and
lock waits. Preserve the old control-plane directory in the existing
archive, while keeping the newer backup and provider files active.
- Restore a current-run external marker only from its own checkpoint
before the existing bootstrap retry proof. A missing current checkpoint
cannot select a previous turn. Retain readable current-run, legacy
file-backed, backup integrity and provider resume checks.
- Stage the existing OpenCode proxy bytes into the controlled
fake-sandbox filesystem in the real ingress-retry fixture. Keep remote
artifact path and digest checks unchanged.
- Add real PostgreSQL/filesystem coverage for Codex and ACPX, readable
projections and external markers, missing or corrupt parts, held owners,
foreign scope, newer history and a current owner arriving during a real
coordinator-lock wait.

## Verification

- Baseline RED: the two new readable-projection cases failed against
unchanged production code because active control-plane state was absent
after admission. The real selector selected the second run. Setup
failures were separate and are not counted as RED.
- Exact final existing per-turn restore, active-owner refresh and
retained-owner wait controls: 19/19 passed in 5.91s.
- Exact final local source (`fd8d9d9021`, based on `131b566ca4`): 58/58
real PostgreSQL/filesystem and native Runner tests passed in 31.58s.
This includes both existing ingress bootstrap retries through the real
Runner and fake Codex/OpenCode providers, plus 56 focused owner cases.
Cargo validated and rebuilt current source from a private APFS clone of
an unqualified local cache; the original cache was untouched. A private
local configuration resolves workspace DB, Shared and Runner sources
without replacing behavior. The local CLI allowed a 90s setup hook; no
default timeout changed.
- Exact final full server and test-tree TypeScript check with Runner
source paths: passed. The stock fresh-worktree check first failed on
unbuilt Runner declaration entries; no product types were changed to
hide that setup gap.
- Exact final module-boundary and diff-whitespace checks: passed.
- Native-server CI RED on the previous head: both real ingress retry
cases failed because a current-run marker was returned without
hydration. The aggregate gate failed from that one underlying lane. The
correction preserves the own-checkpoint bootstrap path. The first local
OpenCode attempt hit a controller-host fixture path guard before its
intended failure; staging the same proxy bytes into the fake sandbox
made both native cases pass.
- Review regression RED: the real retained-sandbox fixture failed at
`sandbox_resumed` on the first PR head. GREEN: the corrected owner
hydrates the same-source marker and reaches the existing exact
retained-lease/suspended-runner read. A mismatched item identity still
refuses before any remote read.
- Local environment: macOS arm64, Node 26.4.0, PostgreSQL 18.1. Provider
execution is deliberately outside this admission fixture. The real
three-turn workflow still needs verification on the normally deployed
fixed source.

## Risks

- Refresh requires settled, committed, released and stopped or fenced
owners. Missing or changed evidence remains blocked.
- The refresh holds existing coordinator locks while it validates
bounded controller state. It performs no provider calls.
- The old control-plane bytes remain in the archive. A restore write
failure still fails admission; it does not reset provider state.
- Final-head full CI is green, including typecheck, build, Rust,
native-server, server and browser suites; Greptile is 5/5 with no
unresolved threads. Hosted deployment and continuity verification remain
separate acceptance steps. A successful replacement conversation is not
proof of provider continuity; hosted continuity acceptance is still
pending.

## Model Used

OpenAI Codex, GPT-6 family, with code execution and repository tools.
The host does not expose the exact backend model ID or context-window
size.

DottaandClaude Opus 5.5 fc7e3a6503 fix(recovery): never replace a native session after a deterministic refusal (#19733)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native agent runs keep a saved provider session, and same-run
recovery resumes it after a failure
> - When resume fails and the checkpoint allows it, recovery archives
the saved continuity state and opens a fresh replacement session
> - Recovery used that path for every resume failure, including
deterministic refusals that left the saved state unchanged and repeat on
every retry
> - In five staging tasks a refusal (a protected launch argument, or a
predecessor tool call with no result) escalated into a replacement. The
remote archive move failed part way, the next attempt found no runner
state, and each task was blocked for workspace repair
> - This pull request stops before replacement after a closed-class
refusal, keeps the saved state, and hands the run to an operator with a
named reason
> - The benefit is that a deterministic refusal can no longer damage
saved state or open a replacement over an unsettled external action

## Linked Issues or Issue Description

Refs #19659, Refs #19516, Refs #19334

**What happened?**
Five Codex tasks on Daytona sandboxes failed on staging. The first
attempt failed with a deterministic refusal:
- `run.attach cannot change protected launch arguments` (four tasks,
fixed separately in #19659), or
- `native_runner_source_semantic_reconciliation_required` with a
predecessor `paperclip_call_assigned_tool` call still pending (one
task).

The same-run retry then opened a replacement session.
`archiveContinuityState` failed with
`runner_continuity_break_archive_failed` and no detail. The third
attempt failed with `runner_remote_state_unavailable: exit=1`, and the
task was blocked with "Workspace repair required".

**Steps to reproduce**
1. Save a native session whose checkpoint policy is
`allow_replacement_after_resume_failure`.
2. Make the resume fail with a refusal that does not change state (an
attach refusal, or a pending tool call).
3. Same-run recovery opens a replacement session and archives the saved
continuity state.

**Expected behavior**
A deterministic refusal stops the run for an operator. The saved state
stays intact. A run with a pending side-effecting call never reaches
replacement. Transport drops keep the existing retry behavior.

**Root cause**
`executeNativeSession` checked only the checkpoint's replacement policy.
The closed failure class (#19334) only had an effect when replacement
was forbidden. Attach refusals and pending tool calls had no class at
all, and the source-reconciliation refusal was a plain `Error`.

## What Changed

- Runner (`provider_backend.rs`, `durable/mod.rs`): `run.attach`
refusals that would change the durable Codex profile or a protected
launch argument carry the closed classification
`provider_attach_refused`. An attach blocked by
`durable_pending_tool_calls` carries `provider_side_effect_pending`.
These refusals already leave the saved state unchanged.
- Contracts (`harness-driver.ts`): new closed classes
`PROVIDER_ATTACH_REFUSED` and `PROVIDER_SIDE_EFFECT_PENDING`. A typed
`NativeRunnerSourceReconciliationRequiredError` replaces the plain
`Error` at the five `native_runner_source_*_reconciliation_required`
throw sites. `runnerRecoveryFailureClass` reads the authenticated
command-result classification or the typed error, never message text.
- Runtime (`native-session-runtime.ts`): after either class, recovery
never opens a replacement session, whatever the checkpoint policy.
- An attach refusal ends with the existing
`NativeProviderStateIncompatibleError`, which maps to the existing
operator path `native_provider_state_incompatible`.
- A pending side effect ends with the new
`NativeProviderSideEffectPendingError`.
- Server (`native-session-executor.ts`, `native-session-resume.ts`,
shared `EXECUTION_RECONCILIATION_CAUSES`):
`native_provider_side_effect_pending` is a permanent failure and an
execution-reconciliation cause, so the board gets a reconciliation
(record whether the action ran) instead of a generic Retry. The
reconciled continuation does not rebind the saved session, which still
refuses attachment. It starts a fresh provider session in the same
workspace. The saved session and workspace are unchanged.
- Archive (`archiveContinuityState`): a failed remote move now records
the bounded (512 characters), redacted exit status and output in
`runner_continuity_break_archive_failed: exit=… timedOut=… <output>`.
The remote move already ran before the local move on `master`, so a
failed remote move leaves the local state in place.
`restart-interrupted-turn.ts` accepts the detailed message for its
reattachment-loss retry.
- Docs: `doc/execution-semantics.md` and
`packages/paperclip-runner/docs/durable-recovery.md` describe the new
rule.

## Verification

Red before the fix, green after (each test first run against unchanged
source from `origin/master` 644ee66f5d):

- `native-session-runtime.test.ts`, test "never replaces a session after
a deterministic, non-destructive recovery refusal". Red: replacement was
attempted (`TypeError: Invalid value used as weak map key` from the stub
replacement). Green: typed error, and `openReplacementSession`,
`openSession` and `openRun` are not called.
- `harness-driver-backend.test.ts`, test "keeps the runner's closed
class of a failed recovery". Red: the typed error did not exist. Green:
both new classes are read from the command result and from the typed
error. The same message text without the type stays unclassified.
- `tests/codex_provider.rs` (real durable executor and fake Codex
app-server):
-
`attach_with_a_pending_tool_call_is_classified_as_a_pending_side_effect`.
Red: `left: None, right: Some("provider_side_effect_pending")`.
-
`saved_codex_thread_attaches_after_a_release_changes_its_feature_toggles`
(protected sandbox change). Red: `left: None, right:
Some("provider_attach_refused")`.
- `native-session-executor.test.ts`:
- Test "stops same-run retries for an operator while a saved
side-effecting call has no result". Red: `expected
'native_session_interrupted' to be
'native_provider_side_effect_pending'`.
- Test "retains the local controller checkpoint until remote continuity
archiving succeeds: failed/timeout". Red: the message had no detail.
Green: the message has the exit status and output, a token in the output
is redacted, and the local runner and control-plane files are intact.

Safety and regression checks:
- New test "still replaces a session after an unclassified resume
failure when the checkpoint allows it". It passes before and after: a
transport drop still reaches replacement.
- Existing test "types a runner-proven incompatible session when
same-session recovery is required" still passes.
- `native-session-resume.test.ts`: a source stopped with
`native_provider_side_effect_pending` is not rebound.
- `run-completion.test.ts` "replays saved user intent through normal
Retry …" passes with the detailed archive message.
- Runner Vitest: `native-session-runtime.test.ts` and
`harness-driver-backend.test.ts` (266 passed);
`runnerd-codex-transport-warm-attachment.test.ts` and
`codex-app-server-driver.recovery.test.ts` (74 passed).
- Rust: `--lib` (560 passed, plus one ACPX timing test that failed under
load and passed when rerun alone), `codex_provider` (118 passed),
`native_provider_backend` (45 passed), `durable_recovery` (3 passed).

Not run: a live staging recovery at this revision. The local server
typecheck could not resolve the unbuilt runner package, so required CI
provides typecheck.

## Risks

- A run that a replacement session would have continued after an attach
refusal now stops for an operator. The refusal repeats on every retry,
so the replacement was the only way past it. It also destroyed saved
state, which is what blocked the staging tasks. A board Retry still
continues the task in a fresh session in the same workspace. This is the
existing `native_provider_state_incompatible` behavior.
- A new failure code `native_provider_side_effect_pending` appears in
run records and recovery actions. It joins
`EXECUTION_RECONCILIATION_CAUSES`, so the UI shows the reconciliation
flow, not Retry.
- An attach refusal used to reach an automatic replacement; it now needs
one board Retry. This is intended: the replacement archived saved state
and failed part way on staging.
- The pending-side-effect class means "no result delivered to the
runner". The controller replays a recorded tool outcome only after
attach. A call whose outcome the server already recorded therefore also
stops for an operator. That is conservative; the reconciliation shows
the recorded outcome.
- Only a pending tool call classifies an attach blocker. Other blockers
(active turn, ambiguous turn start, active goal) keep their current
behavior.
- The archive error message is longer. The one exact-match consumer now
accepts the `code: detail` form.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, used through Claude
Code with tool use (shell, file edit, browser reads of staging).

DottaandClaude Opus 5.5 c45c7cb854 fix(workspaces): ignore killed-transfer scratch in sparse checkpoints (#19730)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native run in a remote sandbox copies its workspace back to the
host after the turn. A sparse checkpoint copies only changed entries,
and the host validates each entry against the sandbox's own manifest
> - Every Daytona transfer stages a `.paperclip-upload-<uuid>` scratch
file at the sandbox workspace root and removes it only in the same
process
> - A control-plane kill during any transfer leaves that scratch behind.
The sparse checkpoint then recorded it as a workspace file, but
providers never export it. Every later copyback and every saved-work
recovery attempt failed with "Workspace checkpoint payload mismatch"
> - The failed recovery then left an accepted Retry showing "Paperclip
is finishing the saved result" with no run
> - This pull request stops recording transfer scratch, makes the
checkpoint export an exact copy, names the failing entry, and gives a
Retry behind a spent recovery an honest reason and a working action
> - The benefit is that a restart during a transfer no longer makes a
task's saved work permanently unrecoverable

## Linked Issues or Issue Description

Refs #19721 (RC-50: the killed copyback owner; this PR covers the
separate RC-50b cause)

**What happened?**

Restart-chaos waves s12/t01 and s14/t05 (Claude on Daytona). After a
SIGKILL of the control plane, the native result was accepted, and then
workspace copyback failed with "Workspace checkpoint payload mismatch".
In s14 all 6 saved-work recovery attempts failed the same way. A Retry
accepted during recovery kept `retryWait.reason =
finalizing_saved_result` after the recovery budget was spent. No run was
created.

**Steps to reproduce**

1. Start a native Claude run in a Daytona sandbox.
2. SIGKILL the control plane while any provider transfer is in flight.
3. Let the run finish its turn and copy its workspace back.

**Expected behavior**

Copyback succeeds. Provider scratch is not workspace content. A Retry
behind a spent recovery names the failure and can start a new recovery.

**Actual behavior**

The s14 sandbox (6f4a0b6a) still held
`/home/daytona/paperclip-workspace/.paperclip-upload-d99fe36b-5acc-437b-96ad-85d5ff9e79c4.tar`.
Its mtime was 03:29:23, the second of the K4 SIGKILL. The Daytona
provider stages transfer scratch at `remoteDir`, which is the lease
`remoteCwd` (the workspace root). The runtime workspace wipe
deliberately preserves `.paperclip-upload-*`. The checkpoint helper
(`workspace-checkpoint.ts`, `checkpointMain`) recorded the stale tar.
The ordinary export excludes `.paperclip-upload*`, so the host received
nothing for that entry. `validateCheckpointPayload` then threw "payload
mismatch" on every attempt. The file-mode hypothesis was disproved: the
sandbox umask is 022 and the scratch is mode 644.

## What Changed

- `packages/adapter-utils/src/exclude-patterns.ts`: new
`isSandboxTransferScratchPath`, which matches a root-level
`.paperclip-upload-*` entry. This agrees with the wipe's preserve rule
in `buildWorkspaceTarExtractCommand`.
- `packages/adapter-utils/src/workspace-checkpoint.ts`: the sandbox
checkpoint helper skips that scratch. A mismatch error now names the
entry and its recorded, baseline and received forms (kind, octal mode,
short hash; never contents).
- `packages/adapter-utils/src/sandbox-managed-runtime.ts`: the
checkpoint export requests `preserveSourceEntries: true`. The checkpoint
output is an exact copy that the host validates entry by entry. An
ordinary export applies the host umask and drops `._*` and
`.paperclip-upload*` names at any depth. That gives the same permanent
mismatch for a legitimate user file such as `._summary`,
`notes/.paperclip-upload-plan.md`, or a `0775` script.
- `server/src/services/explicit-native-continuation.ts` and
`task-interruption-presentation.ts`: when the run's saved-work recovery
is exhausted, a waiting Retry reports `saved_work_recovery_failed` with
Retry available, instead of `finalizing_saved_result`. The existing task
Retry path starts one new recovery generation.
- `doc/execution-semantics.md`: a short additive note.

## Verification

- `packages/adapter-utils/src/workspace-checkpoint-capture.test.ts` uses
the real checkpoint helper and an export that behaves like Daytona's
ordinary export:
- Before the fix: `Workspace checkpoint payload mismatch at
".paperclip-upload-d99fe36b-….tar": sandbox recorded file mode=644 …;
baseline absent; received absent`. That is the wave error.
  - After the fix: the scratch is not recorded, and validation passes.
- A second case shows that reserved-looking user names and `0775` modes
need the exact export.
- `packages/adapter-utils/src/workspace-checkpoint.test.ts` is an
end-to-end `prepareSandboxManagedRuntime` restore through a provider
model. In that model, ordinary exports drop reserved names and apply the
umask, and preserve exports copy exactly. Two red checks:
- Without `preserveSourceEntries`, it fails with the mismatch on
`._summary`.
- Without the scratch skip, the stale tar leaks into the host workspace.
- Green: the agent file, the `._summary` file and the `0775` mode
arrive, and no scratch arrives.
- `server/src/services/workspace-recovery-preparation-gates.test.ts`,
"names a spent saved-work recovery behind an accepted Retry, and the
next Retry finishes it" (s14 shape):
  - Red: `finalizing_saved_result` after 6 failed attempts.
- Green: `saved_work_recovery_failed` with `canRetry: true`. The next
Retry starts a new generation, recovery completes, and the Retry
continues in exactly one new run.
- Suites: adapter-utils checkpoint, capture, sandbox-managed-runtime,
seed-reuse and managed-seed (168 passed). Server preparation-gates (47),
explicit-native-continuation and task-interruption-presentation (455),
workspace-recovery admission and retry-copyback, and
native-workspace-finalizer. `tsc --noEmit` is clean for adapter-utils
and server.
- Live evidence: I started the stopped s14 sandbox read-only, listed its
workspace, and stopped it again. No Daytona replay was run. The runner
content ID of this checkout matches no built image.

## Risks

- A user file named `.paperclip-upload-*` directly at the workspace root
is no longer captured by a sparse checkpoint. Providers already drop
that name from every ordinary export, and the runtime already reserves
it at the root.
- The checkpoint export now uses the provider's exact-copy mode. A
workspace file with setuid, setgid or sticky bits is refused by that
mode, as it is for the existing exact-copy transfers. The ordinary
export would have stripped those bits and failed validation anyway.
- The stale scratch tar stays in the sandbox. It is ignored, not
deleted, because a concurrent transfer can own a file with the same
prefix.

DottaandClaude Opus 5.5 5cc89b1e4d fix(native): do not charge a restart resume that made progress before the next crash (#19720)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs have an execution recovery budget of three provider
attempts, so a run that keeps failing stops retrying
> - A control-plane crash (no graceful drain) makes the next server
resume the run, and that resume charges one attempt
> - #19625 stopped charging a resume after a graceful drain, but crash
restarts still charge, even when the previous resume did real work
> - On a deploy day with several restarts, a healthy run used up its
budget and the task needed a manual Retry
> - This pull request does not charge a crash resume when the previous
restart resume made recorded progress
> - The benefit is that restarts alone do not exhaust a run that keeps
making progress, and genuine loops stay bounded

## Linked Issues or Issue Description

Refs #19625

**What happened?**
In restart-chaos testing (storm wave, OpenCode run), a run crossed four
control-plane restarts: K1, K1, K2 (drain), K1. Each resume was clean:
the runner restored the session, recorded
`provider_turn_lost_on_restore`, and the #19699 continuation turn then
ran tools for minutes. The two K1 resumes each charged one attempt
(attempt 1 to 3). The drain resume did not charge (#19625). The fourth
restart found attempt 3 and blocked the run with
`native_restart_recovery_blocked` /
`execution_recovery_budget_exhausted`. Seven runs in the same wave
failed in the same way. In every case, each resume had accepted a new
turn and completed tool work before the next restart.

**Expected behavior**
A run must not fail because it survived several controller restarts that
each resumed cleanly and made progress. The budget must still stop a
resume that fails each time, a crash loop that makes no progress, and a
provider that fails repeatedly.

**Steps to reproduce**
Start a native local run. Kill the server (SIGKILL) while the run is
active and let it resume. Let the resumed turn run tools. Repeat three
times. The third crash resume is blocked with
`execution_recovery_budget_exhausted`.

**Paperclip version or commit**
`master` at `8a34c1b62c`.

## What Changed

- `claimNativeRestartRecoveries()` (`native-restart-recovery.ts`)
records `progressWatermarkSeq` (the run's highest
`heartbeat_run_events.seq`) in the history entry of each recovery claim.
- New `previousResumeMadeProgress()`: the next claim reads the watermark
of the most recent claim. It finds progress when, after that watermark,
a `turn.accepted` event names a turn, and a later
`tool.execution.completed` or `item.completed` event (not a `usage`
item) belongs to the same turn. The evidence is committed run events,
not timing.
- When that progress exists, the claim is not charged
(`chargesProviderAttempt: false`, and the `>= 3` exhausted gate is
skipped). This uses the same path as the clean-drain rule from #19625.
The history entry records `attemptKeptForProgress: true`.
- Restore activity does not count: lineage items without a turn,
`turn.failed`, work on the interrupted turn, `turn.submitted`, and an
accepted turn with only usage or a failure. So a resume that dies or
fails before it does work still charges.
- The credit stops at controller generation 12
(`NATIVE_PROGRESS_CREDIT_GENERATION_LIMIT`). A run that does some work
and then crashes the controller every time still reaches the budget.
- The first restart (which interrupts the original execution, not a
resume) still charges. A history entry from an older release has no
watermark, so it gets no credit.
- `doc/execution-semantics.md` states the rule next to the three-attempt
budget.

## Verification

New tests in
`server/src/services/native-runtime/native-runner-restart-recovery.integration.test.ts`
(embedded Postgres, real `claimNativeRestartRecoveries`; between claims
the test applies the executor's attempt charge and marks the controller
dead):

- `keeps recovering a run whose restart resumes each completed work
before the next crash`: five crash resumes, each followed by restore
noise and one completed tool in the continuation turn. Charges are
`[true, false, false, false, false]` and the attempt stays 2. Red on
master (attempt 2, 3, then blocked).
- `still exhausts the budget when restart resumes complete no work
between crashes`: resumes followed only by restore noise and a failed
continuation turn. Attempt 2, attempt 3, then
`execution_recovery_budget_exhausted`. Green on master and with the fix.
- `bounds a crash loop that makes progress before every crash`: credit
stops at the generation limit, the last attempt is spent, and the run
blocks. Red on master.
- `native-runner-restart-recovery.integration.test.ts`,
`heartbeat-native-restart-suspension.test.ts`,
`native-restart-recovery-isolation.test.ts` and
`native-remote-retry-admission.test.ts`: 218 passed, 14 skipped.
- I ran the progress query against the live database of the failing
wave. For all seven blocked runs, every resume had progress before the
next restart, so this rule would have kept each of them recovering.
- `tsc --noEmit` for `server` has no errors in the changed files.

## Risks

- A run that makes progress and then makes the controller crash each
time gets up to about ten extra resumes before the budget applies. The
generation limit bounds this.
- The rule depends on the PRP event shape (`payload.prpEvent.turnId` on
`turn.accepted` and on completed work). Events without that shape get no
credit, so the failure mode is the old behavior (charge), not an
unbounded loop.
- The query runs once per claim, on the `(run_id, seq)` unique index
range after the watermark.

DottaandClaude Opus 5.5 51eb4ff705 fix(recovery): finalize an accepted native result after a hard kill (#19713)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native run hands its accepted result to a controller lease, and
the controller finalizes the task from that result
> - A graceful shutdown releases that lease for the next server
(#19591), but a hard kill (SIGKILL, OOM, host crash) cannot
> - After a hard kill between result acceptance and finalization, the
next server waited for the dead controller's 20-minute lease, so the run
stayed `running` and the user's follow-up comment waited with it
> - This pull request releases that lease at startup when the controller
is proved dead by its boot ID and process identity, never by age
> - The benefit is that the saved result finalizes within seconds after
a restart, without another provider turn, and queued follow-up work
continues

## Linked Issues or Issue Description

Refs #19591 (the graceful-shutdown counterpart) and #19578
(boot-identity proof for legacy runs).

**What happened?**
A restart-chaos wave sent K1 (SIGKILL) 20 ms after a Claude run recorded
`run.result.accepted` and `run.terminal`. The run then stayed `running`
for more than 10 minutes, through four more restarts. The finalization
row was `workspace_finalizing` with the stored result. Its lease
belonged to the killed server: a different `controller_boot_id`, a
`controller_pid` with no process, and `lease_expires_at` 20 minutes
ahead. Startup recovery skips runs that already have a result. The
result-commit worker waits until the lease expires. The task's follow-up
comment could not run until then.

**Steps to reproduce**
1. Let a native local run accept its result.
2. SIGKILL the server before finalization finishes.
3. Restart the server. The run stays `running` until the old lease
expires.

**Expected behavior**
After a restart, a result lease held by a stopped controller of an
earlier boot is treated as released at once. The stored result finalizes
once, with no new provider turn, and the follow-up wake runs after it.

## What Changed

- New
`server/src/services/native-runtime/native-dead-controller-result-lease.ts`:
`releaseDeadControllerResultLeases` finds `running` native runs with an
accepted result and an unexpired lease. It requires the lease to belong
to a different controller boot. It proves the controller stopped with
`evaluateNativeControllerTakeover` (`requireStoppedController`): the
process is dead, or its PID now names another process. It then expires
that lease with a compare-and-set on the exact owner token, boot ID, and
PID, and notifies the result-commit and finalization workers.
- `server/src/services/heartbeat/recovery.ts`:
`recoverNativeRunsAfterRestart` calls this first and records a
`native.recovery.transition` event (`awaiting_result_finalization`) for
each released run.
- Only executor leases are released, because only the executor claim
writes the controller identity together with the lease. Finalizer
(`native-finalizer:`) and cleanup (`native-cleanup:`) claims keep an
earlier executor's identity, so they are never released this way and
expire on their own short leases. A finalization-resume token
(`:resume:`) on a result row always belongs to the executor that adopted
it, because a pending resume claim is taken only on a row without a
result.
- Also not released: a live owner, an owner without a recorded process,
a lease of the current boot, a run this process is executing, and remote
workspaces (`nativeWorkspaceSync` or `remoteWorkspace`), which keep
their fenced lease.
- The compare-and-set does not compare the stored expiry. Postgres
stores microseconds that a JavaScript `Date` drops, and an exact-expiry
comparison silently skipped the real lease in the live reproduction.
- `doc/execution-semantics.md`: documents the rule.

## Verification

- Red then green on embedded Postgres
(`server/src/__tests__/heartbeat-native-restart-suspension.test.ts`):
- A hard kill with a dead controller's executor lease (first claim,
restart claim, or resumed claim) now finalizes on the next startup: run
`succeeded`, finalization `committed`, task `done`, one result, one run,
no provider dispatch. These tests failed before the fix with `status:
running`.
- A lease expiry stored with microsecond precision is released. This
test failed against the first version of the fix and reproduces the live
miss.
- A live controller of another boot keeps its lease, and so does a lease
of the current boot.
- A live claimant's finalizer or cleanup lease is kept when the recorded
earlier executor is dead.
- `npx vitest run
src/__tests__/heartbeat-native-restart-suspension.test.ts`: 20 passed.
- Related suites pass: `native-session-resumption`,
`native-runner-restart-recovery.integration`,
`native-run-projection-work`, `live-recovery-work`. One
`live-recovery-work` legacy case timed out once under load and passed
when run again by itself.
- Live, local: `tests/restart-chaos/main.ts --workloads C1 --triggers
result --faults K1 --rc06-masked`. The failing case above came from such
a wave. I started its kept database and confirmed the stored lease state
and the compare-and-set miss. Against that same database, the fixed
release expires the stuck executor lease. Two later waves (12 tasks,
`--triggers result`) passed every task. Run events were not kept for
passing tasks, so I cannot confirm that a kill landed in the narrow
pre-finalization window in those waves.

- Live proof on head `8971874654`: local ACPX Claude, workload A1, seed
7411, `--triggers result` (a local variant that fires on A1 2.5–3.5 s
after the run's result proposal), `--keep`. The run passed 4 of 4 tasks.
In two tasks, K1 landed 1.5 s and 2.0 s after `run.result.accepted`. On
the next startup, each run recorded "Server restart released the
accepted native result of a stopped controller for finalization"
(`controller_process_dead`). Each finished `succeeded` about 1 s later,
with its task `done` and exactly one run per task (no extra provider
turn). Before this fix, the same shape stayed `running` until the
10-minute budget ran out (seeds 7411, 7422, and 7423 from the RC-33b
investigation in #19691).

## Risks

- Startup could take a lease from a finalizer that is still running.
Mitigations: the lease must belong to another boot, the controller
process must be proved stopped on this host (the same proof the existing
runner takeover uses), and the update matches the exact owner. Remote
workspaces are excluded. Multi-host deployments keep the existing
PID-liveness assumption that `claimNativeRestartRecoveries` already
makes.
- Low behavioral risk otherwise: finalization uses the existing
reconciler path, which #19591 already exercises after a graceful drain.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, run as an agent in
Claude Code with tool use (shell, file editing, local test execution,
live restart-chaos waves).

DottaandClaude Opus 5.5 08f7ac03dc fix(recovery): keep a never-started task waiting through a temporary accounting hold (#19702)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Admission checks every wake. A short company accounting hold can
refuse new work after a control-plane restart.
> - When the hold refused a new task's assignment wake, stranded-work
recovery found the task with no run while the hold was still active. It
moved the task to `blocked` with a board recovery comment.
> - A `blocked` task leaves the stranded-assignment sweep, so nothing
woke it after the hold cleared. The task stayed `blocked` with no run,
no interruption and no Retry.
> - The hold was temporary. Tasks created a few seconds later (after the
sweep) started normally once accounting settled.
> - This pull request keeps a never-started task `todo` while a
temporary budget hold lasts. The existing assigned-todo liveness
dispatch then admits it once the hold clears. The task shows the hold it
waits for.
> - The benefit is that a restart no longer silently drops new tasks
created during the accounting settle window.

## Linked Issues or Issue Description

**What happened?**
In a restart-chaos storm on master `06bbcea12f`, three new tasks were
created while the company accounting hold was active. Each assignment
wake got 409 "Company cannot start work while completed runs await
accounting." (or "...native run recovers its unfinished accounting.").
One task rested `blocked` with 0 runs, interruption `null` and
`canRetry=false`. The other two ran later.

**Root cause**
`reconcileStrandedAssignedIssues`
(`server/src/services/recovery/service.ts`, the
`readInvocationBudgetBlock` branch near line 4826) escalates any
assigned task to `blocked` when a budget block exists. It does this
before the assigned-todo no-run branch, which already skips a
budget-blocked task and dispatches it later. So a task that never
started was treated as failed recovery work. The refused wake itself is
stored as a `skipped` `budget.blocked` diagnostic, which is correct; the
escalation removed the only path that re-admits it.

**Expected behavior**
A wake refused by a temporary admission hold waits and is admitted once
the hold clears, with one run. A real hard stop is still a board
decision. Removed assignees and cancelled tasks still do not wake.

**Steps to reproduce**
Create a company with a hard-stop budget and a completed run that has
`cost_accounting_pending = true`. Assign a new `todo` task. The wake
gets 409. Run the stranded-assignment sweep. Before this change the task
becomes `blocked` and never runs.

Related: #19700 bounds the accounting hold itself. This PR is
independent: it handles what happens to a task whose first wake the hold
refused.

## What Changed

- Stranded-work recovery skips a `todo` task with no run while a
temporary budget hold blocks admission. It does not escalate it to
`blocked`. The existing assigned-todo liveness dispatch admits the task
once the hold clears.
- A hard stop (spend at the limit, or blocked unpriced usage) keeps the
existing board escalation. Recovery checks this with the read-only
`policyBlocks` for the policies of the blocking scope. It does not
change budget hold semantics.
- The task interruption projection now covers a `todo` task with no run
whose latest wake was refused with `budget.blocked`. It shows "Waiting
for the budget to allow new work. The task starts automatically when it
does." with no Retry. A budget pause shows the existing "budget" user
action.
- The no-run projection applies the same person-owned gates as the
run-backed projection: a budget pause shows the "budget" action, and an
ordinary agent, project, company or task pause shows "resume". Only an
accounting hold shows the automatic-start text.
- `ExecutionBlockerNotice` shows that wait text for a `working`
presentation that carries a wait reason.
- `doc/execution-semantics.md` records the rule.

## Verification

- New embedded-Postgres regression
`server/src/__tests__/heartbeat-refused-assignment-wake.test.ts`:
- hold active, new task assigned, wake refused (409, `skipped`
`budget.blocked`), two recovery sweeps: the task stays `todo` with no
run and shows the wait reason. Before the fix this failed with `expected
'blocked' to be 'todo'` (the CHA-9 shape).
- hold cleared, two sweeps: exactly one provider turn starts, from
`issue.assigned_todo_liveness_dispatch`, and the task finishes. A later
sweep does not start another turn.
- counter-tests: a terminated assignee and a cancelled task get no run
after the hold clears.
- Existing `creates a board recovery action for budget-blocked assigned
work` (real hard stop) still passes unchanged.
- `pnpm exec vitest run
src/__tests__/heartbeat-refused-assignment-wake.test.ts
src/__tests__/heartbeat-process-recovery.test.ts
src/services/task-interruption-presentation.test.ts
src/__tests__/heartbeat-issue-liveness-escalation.test.ts` (server) and
`src/components/ExecutionBlockerNotice.test.tsx` (ui).
- Server typecheck and `pnpm check:token-gates`.
- Live restart-chaos storm (local, codex/claude/opencode, 6 in flight,
K2 every 3-4 minutes for 20 minutes, no RC-06 mask), revision
e38bb5c8f7: 17 tasks, 10 pass.
- Two new tasks (CHA-16, CHA-17) were created while the company
accounting hold was active. Their assignment wakes got 409 "Company
cannot start work while completed runs await accounting." Both stayed
`todo` (not `blocked`) and showed `state: working`, `canRetry: false`,
`retryWait.reason: budget.blocked`, "Waiting for the budget to allow new
work. The task starts automatically when it does." No task rested
`blocked` with 0 runs.
- The hold itself never cleared in this wave (`pendingRunCount: 1` at
wave end), so these two tasks did not start before their deadline. That
stuck hold is the separate accounting-closure defect that #19700 bounds.
The other 5 failures (`R3:retry_no_new_run:B5`) are Retries refused by
the same stuck hold. The re-admission after the hold clears is proved by
the embedded-Postgres regression above.

## Risks

- Low. The change narrows one escalation to tasks that never started,
under a budget block that is not a hard stop. Those tasks now stay
`todo` and are re-checked by the existing 30-second stranded-assignment
sweep, which already re-checks every admission gate.
- The hard-stop check reads the blocking scope's active policies once
per budget-blocked never-started task in a sweep. It runs only while a
hold is active.
- The interruption projection adds one indexed read (company + payload
issue id) for `todo` tasks in the batch.

DottaandClaude Opus 5.5 ece09c156a fix(runner): keep an accepted result when ACPX reports its turn lost on restore (#19691)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native Codex, OpenCode, and ACPX runs survive control-plane
restarts: runnerd restores the conversation, and the control plane
continues the task from its checkpoint
> - #19658 made recovery keep a durable result when a Codex restore
loses the turn that proposed it. It covered the recovery read path only
> - ACPX reports the lost turn differently. After the restored
conversation reopens, a live `turn.failed` arrives with
`provider_turn_lost_on_restore`
> - That live terminal still turned an accepted `done` result into a
failed run. The run ended `failed` (`adapter_failed`), and the finished
work needed a Retry
> - This pull request moves the rule into the shared terminal mapping. A
restore-lost turn with a held result for that exact turn settles as
completed, whichever path reports it
> - The benefit is that ACPX and OpenCode tasks that already finished
keep their accepted result after a restart, as Codex tasks now do

## Linked Issues or Issue Description

Refs #19658, #19525, #19501, #19539

**What happened?**
In a restart chaos wave, an ACPX Claude task (workload A1) wrote its
brief and proposed a `done` result (`run.result.proposed`, then a
completed `paperclip_finish` tool call). Then a K1 and a K6 crash loop
hit the control plane, and `resume_dead_runner` ran at controller
generations 2 and 3. The restored ACPX conversation emitted
`turn.failed` with `provider_turn_lost_on_restore` (`recoverable: true`)
for the checkpointed turn. The control plane then emitted
`run.result.accepted` with the `done` result, but `run.terminal` came
back `runTerminalState: failed` / `turnTerminalState: failed` /
`reportedWorkDisposition: done`. The run ended `failed` /
`adapter_failed`, "Native session failed".

**Steps to reproduce**
1. Start a native ACPX (or OpenCode) task through runnerd.
2. Let the agent call `paperclip_finish`, and let the control plane
persist the proposal.
3. Kill the control plane and runner before the turn ends.
4. Let restart recovery resume the run. The restored runner reports the
turn lost on restore as a live terminal.

**Expected behavior**
Recovery finalizes the accepted result, and the run succeeds.

**Actual behavior**
ACPX and OpenCode use the same Codex harness session as Codex
(`codex-native-backend.ts`). Recovery restored the held result for the
turn from the durable proposal. But the live `turn/completed`
notification with `status: failed` and `provider_turn_lost_on_restore`
went through `mapTerminalTurn`, which emitted `turn.failed`. The backend
maps `turn.failed` to `runTerminalState: failed`. #19658 handled only
the `thread/read` reconciliation path.

## What Changed

- `codex-session-terminal.ts`: a new
`settleRestoreLostTurnWithHeldResult` helper. When a terminal is
`failed` with `provider_turn_lost_on_restore` and the session holds the
semantic result that this exact turn proposed, the turn settles as
`completed`. `mapTerminalTurn` applies it first, so live notifications
and recovery reads follow one rule.
- `codex-session-terminal.ts`: the helper also covers
`acpx_active_turn_recovery_closed`. Runnerd's ACPX backend
(`acpx_provider_backend.rs`, `restore_session_if_needed`) emits that
code instead of restoring the conversation when its own state already
recorded the accepted result. It is the same restart loss, with the
result already accepted. #19525 already keeps accepted results when
close cannot prove suspension, and session close still handles
`provider_exit_unconfirmed`.
- `codex-harness-session.ts`: `reconcile()` keeps only the missing-turn
case from #19658. The restore-lost read case and the prior-terminal
check now use the shared helper.
- `doc/execution-semantics.md`: the restart paragraph now states that
the rule covers Codex, OpenCode, and ACPX, and both report paths.

## Verification

- Red before the fix, with the real Codex native backend
(`createCodexNativeSessionBackend`) and a fake transport through
`executeNativeSession`: `pnpm --filter @paperclipai/paperclip-runner
exec vitest run src/native-session-runtime.test.ts -t "journaled
completion proposal"`. The new `restore-lost live` scenario failed.
Green after the fix: the run completes with the journaled result on
`turn-1` and a succeeded terminal, and no `turn/start` is sent. The
`restore-lost read` scenario passes on both (#19658 already covered it).
- Driver red/green:
`src/drivers/codex/codex-app-server-driver.recovery.test.ts -t "live
restore-lost"`. With a held result, the live lost terminal was
`turn.failed` before the fix and is `turn.completed` after it. With no
held result, it stays `turn.failed` with the lost cause, so the #19501
continuation is unchanged.
- The driver case was extended to `acpx_active_turn_recovery_closed`
(red with a held result before the extension, then green). It was found
in a live replay where the run ended `failed`/`adapter_failed` with an
accepted `done` result.
- Suites: `src/drivers/codex/` and `src/native-session-runtime.test.ts`
(580 tests), plus `src/backends/` and
`src/live/runnerd-restart-continuation.test.ts`, pass.
`typecheck:typescript` passes.
- Live chaos replays (ACPX Claude): results and a separate new signature
are in a comment below.

## Risks

- The rule needs a held result whose turn id equals the lost turn.
Recovery restores that result only from the durable
`run.result.proposed` for the checkpointed turn, so a result for another
turn does not settle it.
- A restore-lost turn without a held result keeps its failure and the
bounded same-conversation continuation.
- Real provider failures and other terminal states are unchanged.
- No schema, profile, pack contract, or database changes.

DottaandClaude Opus 5.5 f09b4704b6 fix(recovery): keep the agent's work when Retry continues after exhausted or blocked recovery (#19666)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Task recovery restarts agent work after a control-plane restart or a
failed run
> - When automatic recovery runs out or is blocked, the user clicks
Retry
> - Retry then started a fresh isolated attempt cloned from committed
HEAD, so the agent lost its uncommitted files, its task branch and the
worktree Git link
> - A restart must never lose the agent's work
> - This pull request makes Retry keep the task's own workspace when
that is safe, and tells the agent where the old files are when a fresh
attempt is still required
> - The benefit is that a Retry continues the real work instead of
starting over

## Linked Issues or Issue Description

**What happened?**
After `native_restart_recovery_blocked` or an exhausted recovery
generation, a Retry ran in
`isolated-workspace-attempts/<company>/<issue>/<run>/workspace`. That
directory was a detached clone of the base ref. It did not contain the
uncommitted edits from the issue's git worktree. It was not on the task
branch. The agent was not told where the old files were. A restart-chaos
wave graded this as an R2 failure (`pre_fault_files_lost`). A second
defect: when a restart hit the bootstrap of a fresh attempt, preparing
the same run again failed with
`isolated_task_directory_binding_mismatch`, so the Retry could not
finish.

**Expected behavior**
Retry continues in the task's own workspace with its edits and `.git`
intact when no other writer can hold it. When a fresh attempt is really
needed, the old directory stays as it was and the agent gets its path
and its changed files. Preparing the same attempt again after a restart
is idempotent.

**Paperclip version or commit**
`master` at `e482f0f632`, restart-chaos waves on 2026-11-06.

**Steps to reproduce**
1. Start a native task in a git worktree. Let the agent write an
uncommitted file.
2. Kill the control plane so recovery ends in
`native_restart_recovery_blocked` or an exhausted generation.
3. Click Retry.
4. The successor runs in a fresh clone without the uncommitted file or
the task branch.

Root cause:
- `server/src/services/fresh-workspace-continuation.ts`
`canSelectFreshWorkspace` returns a fresh intent for every task Retry
that has a system recovery record.
- `server/src/services/explicit-native-continuation.ts` (fresh selection
in the source loop) then always persisted `fresh_isolated_workspace`.
- `server/src/services/fresh-workspace-seed.ts`
`materializeFreshWorkspaceSeed` clones the project source at the base
ref with `--no-local`, checks out a detached commit and removes
`origin`. Uncommitted work and the branch are not carried over.
- RC-35: `server/src/services/heartbeat/workspace-preparation.ts`
rejected any reusable existing workspace while `fresh` was true,
including the attempt directory that the same run had already created
and bound.

## What Changed

- New continuation mode `reuse_issue_workspace`. At Retry admission,
after all stop proofs pass, `retainedIssueWorkspaceForRetry` checks that
the task's bound workspace is the single local directory the failed run
used, owned by the task, not a shared workspace, not under remote
storage authority, with no other lease, failed cleanup or running
workspace operation, a settled recovery generation, no workspace-export
failure, and a readable Git state rooted at that directory. Then the
Retry continues there with a fresh session. Otherwise the existing fresh
attempt is kept.
- The reuse decision consumes the generation's one alternative attempt
(`freshAttemptRunId`), sets the Retry strategy to `continue`, and
records `issue.retry_workspace_reused`.
- Environment selection pins the reused workspace binding and fails with
`retry_workspace_binding_mismatch` if the binding changed before
dispatch.
- Fresh fallback: the run's continuation context gets `priorWorkspace`
(path, branch, bounded list of uncommitted files). Git status is read
with optional locks disabled. The prompt tells the agent to inspect it
and carry over the work. The old directory is not changed.
- RC-35: preparing the same fresh attempt again after a restart reuses
the attempt directory that this run already bound.
- Reuse checks run Git through the shared workspace scan scheduler with
short deadlines, because admission can hold the issue lock.
- `doc/task-recovery.md` and `doc/execution-semantics.md` describe the
new contract.

## Verification

- `server/src/services/retry-workspace-continuity.test.ts` (embedded
Postgres, real git worktree with uncommitted edits):
- exhausted-generation Retry and blocked-recovery Retry continue in the
same worktree, `.git` file and branch intact. Both failed before the fix
(readiness was `fresh_isolated_workspace`).
- Blocked recovery without a generation and duplicate holds for one run
also reuse the worktree. A running operation orphaned by a restart of
the stopped source does not block reuse.
- The fresh attempt is kept when the workspace is unsafe: live lease,
running workspace operation, corrupt `.git`, missing directory, remote
authority, shared workspace, running export generation. `priorWorkspace`
is omitted for the unsafe writer and shared cases.
- `workspace-preparation.test.ts`:
- A `reuse_issue_workspace` Retry prepares in the original worktree with
its uncommitted file and branch.
- RC-35 red/green: re-preparing the same fresh attempt reuses its bound
directory and keeps files written before the restart. Another run still
gets `isolated_task_directory_binding_mismatch`.
- The fresh fallback sets `priorWorkspace` with the old path and
`unpublished.txt`.
- `environment-selection.test.ts`: the new mode pins the binding and
rejects a changed binding or cwd.
- `packages/adapter-utils/src/server-utils.test.ts`: the prompt names
the retained directory and its files.
- Regression files run locally: `workspace-preparation`,
`environment-selection`, `task-retry`, `quarantined-task-retry`,
`explicit-native-continuation`, `workspace-recovery`.
- Restart-chaos (`tests/restart-chaos`, local, B1+B5, codex+claude,
K1/K4/K6, concurrency 2, rc06-masked):
- Final head: wave `w-20261107T014633-s7206` on `c6776283f3`: 8/8 PASS,
all 8 restart-crossing. 5 tasks needed a Retry (t03-t07: codex B1 K6,
codex B1 K1, codex B5 K6, codex B5 K1, claude B5 K6). All five finished
in the original git worktree with `.git` and every pre-fault file
present (`workspaceMovedTo` empty, `lostFiles` empty); no "Retry keeps a
fresh attempt" log line.
- Wave `w-20261107T004829-s7205` on `29373a6b6a`: 8/8 PASS, all 8
restart-crossing. 3 tasks needed a Retry (t02, t06, t07). All three
finished in the original git worktree with `.git` and every pre-fault
file present; no "Retry keeps a fresh attempt" log line. (`cc178492ef`
only makes the operation filter stricter for run-less jobs.)
- Wave `w-20261107T000412-s7204` on `d197082107`: 8/8 PASS, 7
restart-crossing. 3 tasks needed a Retry (t02, t04, t06). All three
finished in the original git worktree (`workspaceMovedTo` is empty), R2
passed with `.git` and every pre-fault file present, and no "Retry keeps
a fresh attempt" log line appeared.
- Wave `w-20261106T231416-s7203` on the first commit: 6/6 PASS, but its
t01 Retry still moved to `isolated-workspace-attempts`. That instance
was not kept, so the exact rejection was not recorded. The likely cause
is a `running` workspace operation that a killed server left on the
stopped source (the source restarted three times). The second commit
treats such restart orphans as not live and logs the rejection reason. A
`--replay` of that t01 on `d197082107` finished in the original worktree
with its `.git` file and no attempt directory.
- Review follow-ups in `d197082107`, `29373a6b6a`, `cc178492ef` and
`c6776283f3` (run-less workspace jobs still block reuse; red/green
covered by the `running_operation` case): holds are grouped by source
run; the readiness fallback (blocked recovery without a generation) also
reuses the task workspace; Git probes go through the shared scan
scheduler with 10-15 s deadlines; `priorWorkspace` is only set for a
task-owned directory with no other writer; the reuse rejection reason is
logged; `priorWorkspace` uses the same task-owned, settled,
single-writer predicate as reuse; Git probes share one budget per
workspace; the RC-35 check is a pure path check; renames are parsed from
either porcelain column.

## Risks

- A Retry now writes into the old directory instead of a new one. The
checks above prevent a second writer. A stale binding fails the run with
`retry_workspace_binding_mismatch`; it does not write to another
directory.
- If the cause of the failure was inside the workspace itself, reuse
could repeat it. Workspace-export failures, restore failures and
required workspace recovery keep the fresh attempt.
- A workspace operation of the stopped source that started before the
source settled and before the current server process no longer blocks
reuse (a restart orphan). Operations with no run, of another run, or
started in the current process still block it.
- `priorWorkspace` is an optional new field in the continuation
envelope. Older adapters ignore it.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, used through Claude
Code with tool use (shell, file edits, test runs).

## Linked Issues or Issue Description

Refs #19501, #15297, #19658, #19539

**What happened?**

Restart storm 3 (seed 7103, RC06 mask on, load 9–12). Codex B5 Retry
runs crossed one K1 restart mid-turn. After the restart, recovery
resumed the dead runner. The runner restored the conversation and
recorded `turn.failed` with `provider_turn_lost_on_restore`
(`recoverable: true`). The control plane started the same-conversation
continuation (`resumeInterruptedTurn` → `startTurn`). About 1 s later
the transport closed with `protocol_failure:turn_binding_mismatch`. The
run failed as `native_runner_process_exited: runnerd exited before
provider turn startup`. The task needed another Retry.

I reproduced it with the focused cell (`--workloads B5 --faults K1
--triggers retry`) and a temporary diagnostic. The failure is "Provider
semantic result did not name the active turn": a `paperclip/runResult`
reached the Codex driver while the continuation's `turn/start` was still
pending and no turn was bound. The driver waits for a pending start
before it handles `turn/completed`, but not before it handles
`paperclip/runResult`.

**Expected behavior**

After a restart that loses a turn, the run continues automatically when
that is safe. Each admitted restart attempt can continue once, within
the provider-attempt budget. A failure names its real cause.

**Steps to reproduce**

1. Run `node cli/node_modules/tsx/dist/cli.mjs
tests/restart-chaos/main.ts --env local --adapters codex --workloads B5
--faults K1 --triggers retry --tasks 2 --concurrency 2 --seed 4040
--rc06-masked`.
2. When a lost turn's continuation receives a semantic result before its
start settles, the run fails with `turn_binding_mismatch` and the task
needs a Retry. The race is intermittent: 1 of about 14 lost turns in my
runs.

**Root cause**

-
`packages/paperclip-runner/src/drivers/codex/codex-session-notifications.ts`:
the `paperclip/runResult` branch checked the active-turn binding without
waiting for `state.turnStartSettled`. The `turn/completed` branch
already waits.
- `codex-harness-session.ts` `startTurn`: the driver's own protocol
failure closed the transport. The pending start then reported the runner
exit, which hid the cause.
- `codex-session-terminal.ts` `mapTerminalTurn`: a consumed one-shot
marker blocked every later continuation in the run, even when the newly
lost turn was that continuation itself.

The one-continuation allowance is per run, not per issue or session
lineage: attaching a new run resets the marker. The storm runs did
attempt their continuation; the start race made it fail.

## What Changed

- Codex driver: a `paperclip/runResult` waits for a pending turn start
to settle before it is bound, like a terminal.
- Codex driver: when this session's own protocol failure ends a pending
turn start, `startTurn` throws `codex_turn_start_protocol_failure:
<code>: <message>` instead of the runner exit. CodexRpc errors and
protocol-integrity errors keep their own types. The server now
classifies this as `native_session_interrupted` instead of
`native_runner_process_exited`; both are retryable.
- A later restart that loses the continuation turn itself re-arms the
one-shot marker: the driver resets it as it was before the first
continuation. It does this when it maps the lost terminal, including
during recovery from a checkpoint taken while the continuation ran. The
checkpoint gate `nativeRestartInterruptedTurnId` stays strict: a
consumed marker still means the allowance is used. Each continuation
still needs an admitted dead-runner restart. The existing
provider-attempt budget bounds the repeats, and an exhausted budget
still blocks with Retry.
- `doc/execution-semantics.md`: an additive paragraph.

## Verification

Red before the fix, green after:

- `codex-app-server-driver.events.test.ts` "binds a semantic result that
arrives before its pending turn start settles". Red: `session.failed`.
Green: the result binds to `turn-1` and the turn completes.
- `codex-app-server-driver.events.test.ts` "names its own protocol
failure when that failure ends a pending turn start". Red: "runnerd
exited before provider turn startup". Green:
`codex_turn_start_protocol_failure: turn_binding_mismatch`.
- `codex-app-server-driver.recovery.test.ts` "offers another restart
continuation when a later restart loses the continuation turn itself".
Red: `null`. Green: `turn-2`. A checkpoint with a consumed marker still
returns `null`.
- `codex-app-server-driver.recovery.test.ts` "re-arms the continuation
when recovery finds the checkpointed continuation turn lost". This
recovers from a checkpoint taken during the continuation, then starts
the next continuation. Red without the re-arm (the marker stays
consumed); green with it.
- `native-runner-restart-recovery.integration.test.ts`: the same
checkpoint (continuation active, consumed marker naming it) is claimed
as `resume_dead_runner`. This is regression coverage.

Suites run locally on the final code:

- Runner: Codex driver, `native-session-runtime`,
`runnerd-restart-continuation` and contracts (745 tests).
- Server: `native-runner-restart-recovery.integration.test.ts`.
- `tsc` for the runner tests and the server.
- A few real-process tests timed out at about 6 s while six live agents
ran. Each passed when rerun alone. The settlement suite passed both with
and without this change at the same load.

Live (local, real Codex, macOS arm64), focused restart-chaos cell
`--adapters codex --workloads B5 --faults K1 --triggers retry,time
--tasks 6 --seed 4042 --rc06-masked`: 6/6 crossed a restart and passed.
R1 passed for all 6, so each continued without a Retry.

## Risks

- A run can now continue more than once in the same conversation, once
per admitted restart. Each continuation asks the agent to reconcile
unfinished actions before repeating them. The provider-attempt budget
still caps the repeats.
- A semantic result that arrives during a pending start now waits for
that start. If the start fails, the result is still rejected by the
existing binding check.
- The start race was intermittent (1 of about 14 lost turns), so the
live cell shows absence of the failure, not a forced repro. The driver
regression reproduces it deterministically.
- No schema, API or migration change.

## Model Used

- Anthropic Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with
tool use, code execution, and extended reasoning.

DottaandClaude Opus 5.5 9a52a2dfeb fix(native): retry ACPX session.open startup timeouts and give cold Claude a 60 s bound (#19661)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native runs start an ACPX provider through Runner. `session.open`
opens the provider session before any prompt.
> - On a loaded host, a cold ACPX Claude `session.open` took longer than
its 30-second bound. The controller reported
`runner_local_connect_failed: PRP command session.open timed out`.
> - The server classified this as the generic
`native_session_interrupted` with `ambiguous_state`, so the task was
blocked at once. A person had to click Retry, sometimes several times.

another task both Retry runs timed out too.

## Linked Issues or Issue Description

Refs #18854 (bounded bootstrap retry for definite `session.open`
failures), #19487 (60-second cold OpenCode admission), #19665 (the
bootstrap proof that this change reuses).

**What happened?**

ACPX Claude runs failed with `runner_local_connect_failed: PRP command
session.open timed out` about 35 to 40 seconds after they started. The
coordinator recorded `native_session_interrupted` with `recoveryMode:
"ambiguous_state"` and `providerSessionEstablished: false`. The task was
blocked with a board-owned action. No provider event and no checkpoint
existed. The host 1-minute load was 17 to 44, sometimes with no restart
nearby.

**Expected behavior**

A normal slow cold start completes. A `session.open` that still times
out during runner startup, with no provider event, no checkpoint and no
turn, retries on the same run with backoff. At most two automatic
attempts follow the first. A run where provider work may have started is
never retried automatically.

**Steps to reproduce**

1. Run ACPX Claude tasks on a host with a 1-minute load of about 25 or
more.
2. Observe a run fail after about 35 to 40 seconds with `PRP command
session.open timed out`.
3. Observe the task blocked with `ambiguous_state` and a manual Retry.

**Paperclip version or commit**

`master` at `6c7cc2c5d6`.

## What Changed

The bound (evidence below):

- `coldAdmissionTimeoutMs` gives cold ACPX Claude 60 seconds (live
adoption keeps 30 seconds). The runner's Rust sidecar
`session_open_timeout` and the sidecar's provider handshake
(`acpxSessionHandshakeTimeoutMs`) give Claude and Pi 60 seconds too. All
three bounds must agree, or the shortest one fails first. Claude's warm
run attachment uses the same cold budget, like Pi.

The automatic retry:

- `nativeSessionFailureSourceCode` returns
`provider_session_open_timeout` only for exactly `<startup failure
code>: PRP command session.open timed out`. The startup failure codes
are `runner_local_connect_failed`, `runner_direct_wss_failed` and
`runner_ingress_unavailable`. The transport uses them only before
startup completes. After startup the code is
`provider_transport_failed`, which is unchanged.
- `nativeProviderRecoveryEvidence` treats the cause as pre-session.
Durable evidence still decides: a bootstrap retry needs no provider
event (`session.started`, `turn.started` and the others) and no
checkpoint. The existing budget applies: three attempts with backoff of
about 30 seconds, then about 60 seconds. When the budget is used, the
task is blocked with the existing "Provider startup failed on 3 attempts
before any provider work began" action.
- A timeout is indeterminate: the runner can open a provider session
after the controller stops waiting. Live runs showed both leftovers, so
the retry now starts from clean state:
- `prepareNativeSessionOpenTimeoutRetry` (server) runs when the failure
settles. It quarantines a local runner root only when the
restart-recovery proof (`runnerdStateProvesIncompleteBootstrap`, #19665)
shows that no turn began and every recorded process is gone. Any other
root, and any remote runner, stays `ambiguous_state` as before.
- `resetAbandonedBootstrapRecord` (runner ACPX adapter) runs on a fresh
open (no runner-recorded identity). If ACPX has a saved record for the
session key with no messages, no prompt and no events, it is marked
`reset_on_next_ensure`. Claude saves nothing before the first prompt, so
reusing such a record fails the first turn with
`session_resume_required`. A record that holds any conversation is
unchanged.
- A chat retry of an exhausted `provider_session_open_timeout` run is
accepted like the other pre-provider causes.
- `doc/execution-semantics.md` and the Runner README describe the cause
and the bound.

## Verification

**Measured startup distribution** (ACPX Claude
`runner.session.bootstrap` / `runner.session.startup` spans from
restart-chaos run events, 1-minute load 8 to 44):

| Source | Bound | Successful cold bootstraps (s) | Failures |
| --- | --- | --- | --- |
| Earlier storm evidence | 30 s | 2.9, 4.7, 7.4, 8.6, 8.7, 26.2, 27.4,
27.6, 29.2 | startups ended at 34.9 to 40.3 s (the 30 s `session.open`
bound plus spawn and `run.prepare`) |
| This branch, wave s3601 | 60 s | 6.3, 7.8, 8.1, 13.4, 14.4, 22.3,
22.8, 22.9, **37.3** | 0 `session.open` timeouts |
| This branch, wave s3602 | 60 s | 13 samples, p50 10.5, p90 17.9, max
25.7 | 0 `session.open` timeouts |
| This branch, wave s3610 (final head, load 28 to 42) | 60 s | 10.4,
11.3, 11.7, 12.0, 13.3, 14.2, 29.6, **30.4**, **30.9** | 0
`session.open` timeouts |

Under load, successes clustered just under 30 s and failures sat just
above it, so the 30 s bound was cutting the distribution off. With 60 s,
cold starts of 30.4, 30.9 and 37.3 s succeeded that the old bound would
have failed. 60 s is about 1.6 times the largest observed success, and
it matches Pi and OpenCode.

**Live restart-chaos waves** (local, ACPX Claude only, 4 in flight,
`--rc06-masked`, real provider, K1/K2 restarts):

- s3601 (8 tasks, load 19 to 32): 7/8 PASS. No `session.open` timeout.
The one failure is an R3 Retry signature after K1
(`native_restart_recovery_blocked`), not this cause.
- s3602 (8 tasks, load 17 to 39): 8/8 PASS. No `session.open` timeout.
Three Retry clicks were for `native_provider_terminal_failed`
(`provider_turn_lost_on_restore`), a different restart signature.
- Forced timeout, s3609 (4 tasks, B5, K2): a local, uncommitted fault
injection gave every other cold startup a 1.5 s `session.open` deadline.
Result 4/4 PASS. Run 4fe6537a timed out, retried itself on the same run,
and then succeeded through four K2 restarts with no person involved. Run
02799a85 hit the injection three times in a row; the budget stopped it
after attempt 3, and one Retry completed it.
- Before the two clean-state fixes, the same forced wave (s3607 and
s3608) showed the retry reusing leftover state: `turn.start` failed with
`session_resume_required`, and then "ACPX session is not open". Those
runs are the red evidence for the two clean-state fixes.
- Final head, s3610 (8 tasks, K1/K2, no injection, load 28 to 42): **8/8
PASS**, 0 `session.open` timeouts. The one Retry click (t06) was for
`provider_turn_lost_on_restore`, a different restart signature.

**Tests:**

- Red before the fix: `native-startup-retry.integration.test.ts -t
timeout` (embedded PostgreSQL, real executor, real resume claim). The 3
retry cases failed with `native_session_interrupted` /
`ambiguous_state`.
- Green: `native-startup-retry.integration.test.ts` passes 36/36. New
cases:
- for each startup failure code, a timeout retries on the same run with
backoff, keeps the task `in_progress` with an agent-owned
`resume_native_run` wake, and blocks after attempt 3 with a board-owned
action;
- no automatic retry when `session.started` or `turn.started` is
durable, when the code is `provider_transport_failed`, or when another
command timed out;
- a real runner root with an opened session and no turn is quarantined;
a root with a turn command stays `ambiguous_state` and intact; a remote
runner is never prepared.
- `codex-runtime-adapter.test.ts`: 113 pass. New cases: a 45 s delayed
handshake is admitted for Claude and rejected for Codex; a
never-prompted record is reset only on a fresh open; records with
messages, a prompt or events are kept.
- `abandoned-bootstrap-record.test.ts` (real `createAcpRuntime` with
`createRuntimeStore` and a controlled ACP peer that, like Claude, cannot
load a never-prompted session): without the reset, a fresh open reuses
the record and the first turn fails with SESSION_RESUME_REQUIRED after
`session/load`. With the reset, the provider receives `session/new` and
the turn completes.
- `vitest run src/drivers/acpx src/cli` in the runner: 107 files, 1,935
tests pass.
- `native-session-executor.test.ts -t "session.open|startup|bootstrap"`:
144 pass. `runnerd-codex-transport.test.ts -t "cold process admission"`:
4 pass. `cargo test -p paperclip-runner-core --lib admission_budget`
passes.
- `npx tsc --noEmit -p server` and the runner `tsc -p
tsconfig.test.json` pass.

## Risks

- **This changes Runner Rust code. The Daytona runner image must be
rebuilt after merge** for remote sandboxes to get the 60-second sidecar
bound. Until then, a remote Claude `session.open` still fails at 30
seconds in the sidecar (as a definite failure, which already retries). A
remote timeout stays operator-owned, because a remote root cannot be
proven clean here.
- A cold ACPX Claude start that hangs now fails after about 60 seconds
instead of 30 seconds.
- A timed-out `session.open` may have created an empty provider session.
No prompt was sent. The retry quarantines that runner root and asks ACPX
for a new session.
- Same-run retries of a fresh-attempt Retry run can still fail with
`isolated_task_directory_binding_mismatch`. This is RC-35 (workspace
re-preparation), which has its own fix in progress.
- No schema or API change. The new error code appears on runs and in run
error codes.

DottaandPaperclip 254b44f72b fix(remote-workspaces): recover retired roots that cannot be renamed (#19674)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Remote workspaces must retain saved files across process and sandbox
replacement.
> - Restore uses identity receipts to distinguish a retired owned root
from an unrelated directory.
> - Some overlay filesystems reject a directory rename with EXDEV even
within one mount.
> - That error currently prevents a valid saved workspace from being
restored.
> - This pull request replaces only a verified retired root in place
when that rename fails.
> - Runtime state stays in place. Each restore holds a root-specific OS
lock.
> - A durable workspace epoch fence rejects delayed older commands. A
pending marker keeps interrupted cleanup recoverable.

## Linked Issues or Issue Description

**What happened?**

Workspace restore fails with `remote_workspace_restore_failed:
stage=publish code=EXDEV syscall=rename` when the retired directory
comes from a lower overlay layer. Retry repeats the same rename.

**Expected behavior**

Restore should publish the verified saved workspace and preserve runtime
state. An interrupted restore should remain safe to retry.

**Steps to reproduce**

1. Create an owned retired root with a valid identity receipt, runtime
state, and stale files.
2. Make directory rename return EXDEV for the existing lower-layer root.
3. Restore a saved workspace through `restoreRemoteWorkspaceDirectory`.
4. Repeat with an interruption before the new restore receipt is
published.

**Paperclip version or commit**

The regression fails before this change on base
`a2aa69bc6230c8b81de3588d7d5571b38db4dd04`.

**Deployment mode**

Remote sandbox with an overlay filesystem. Local regression: macOS
arm64, Node 26.4.0, source checkout.

Refs #19231. Refs #19251. Those changes establish the retained-root
restore path. This fix handles its EXDEV publication failure.

## What Changed

- Keep the EXDEV fallback limited to a verified retired workspace root.
Preserve runtime state and the existing ownership checks.
- Hold a private SQLite OS lock across receipt checks, file replacement,
cleanup, and receipt publication. Keep the lock file outside the
replaced root. Process exit releases ownership; a lost reply does not.
- Pass the existing workspace authority epoch from the real restore
caller. Write and sync a separate epoch fence before root changes.
Reject lower epochs, conflicting identities within one epoch, and
missing epochs on fenced roots. The fence survives SQLite rollback after
process death.
- Publish a pending marker without a completed identity until stale
preparation-receipt removal and directory-mode cleanup finish. A retry
can finish that cleanup. A higher authorized epoch can then restore its
selected save.
- Preserve later file and permission edits when adopting a completed
restore. Refuse unsafe lock files and malformed authority records.
Document compatibility and the stop-evidence boundary.

## Verification

- RED before the original fix: real restore commands failed with EXDEV.
The test preload changes only the kernel rename result.
- RED before the review fixes: a live command with an unconfirmed
timed-out reply overwrote edits made after retry. Tests also reproduced
incomplete cleanup after receipt publication.
- RED before the authority fence: a delayed older command replaced a
newer completed restore. It also passed after the newer command was
killed before root mutation. The final test uses real separate Node
processes, OS lock contention, SIGKILL, and a durable on-disk fence.
- Final local checks: 142 transport filesystem tests, 16 real PostgreSQL
restore-caller cases, and all seven server typecheck layers. The caller
cases verify the published receipt uses the current workspace epoch.
- Late review RED: an actual separate SQLite owner made the real
PostgreSQL restore caller mark an expired lock wait non-retryable.
Corrupt fence and receipt bytes also produced a raw syntax error without
the required refusal reason. Both regressions now pass. Only the test
clock advances the lock deadline; actual OS lock contention and the
production caller run unchanged.
- Lock contention stays retryable only under the existing same clean
writer, epoch, and snapshot proof. Four negative cases change those
fields and remain non-retryable. After the owner stops, normal restore
returns the useful saved files. Corrupt authority records stay untouched
and non-retryable.
- Safety cases cover same and different authorized identities,
process-death lock release, an unrelated root making progress, pending
cleanup interruption, malformed or missing fences, invalid input, and
unsafe lock parents/files.
- The first final transport attempt passed 139 cases and failed only
because the restricted shell could not open a Unix socket (`listen
EPERM`). The full suite was then run with the required local socket
permission. No production change was made for that setup failure.
- Reproduce the filesystem checks from `server/`:
`../node_modules/.bin/vitest run --config vitest.config.ts
src/services/remote-workspace-transport.test.ts`. Run the caller file
with `-t "restores a newer save over this workspace|preserves the
published workspace path"` and the repository test PostgreSQL setup. Run
`node scripts/typecheck-layers.mjs` from `server/` for all seven layers.
- Agent preflight, module boundary audit, and `git diff --check` passed.
No added code comments or private issue references occur in the patch.
- Local EXDEV proof uses macOS arm64 and Node 26.4.0. It does not claim
a new Linux overlay-kernel run or hosted recovery. Final source:
[`8092cc6b2ec448ff372337b1e7a43854eae7bb08`](https://github.com/paperclipai/paperclip/commit/8092cc6b2ec448ff372337b1e7a43854eae7bb08).
[Exact-head
CI](https://github.com/paperclipai/paperclip/actions/runs/42321313715)
completed with 59 successful checks, three conditional skips, and one
neutral check. Greptile gave this exact head 5/5. The independent review
passed. No review threads remain open.

## Risks

The EXDEV path changes files in place. It must finish before execution
admission. Participating restore commands use a private permanent SQLite
lock file and a separately synced epoch fence. The qualified sandbox
Node runtime must support `node:sqlite`. Lock contention has a
120-second limit and does not clear live ownership.

A legacy command that never acquired this lock remains outside its
protection. Hosted recovery must confirm that command stopped; a timeout
is insufficient. The new fence does not backfill that evidence. A
conflicting identity in the same epoch or a malformed fence stays
blocked. A higher epoch can recover an interrupted pending restore only
with the existing retired-root replacement authority. No controller
database schema, execution permission, or provider-state guard changes.

## Model Used

Anthropic Claude Opus 5.5 (`claude-opus-5-5`) authored the recovered
patch. OpenAI Codex, GPT-6 family, recovered, reproduced, repaired the
review findings, and verified the change with filesystem tests, shell
tools, and code execution. The Codex exact serving model ID and
context-window size are not exposed in this session. No value is
inferred for them.

DottaandClaude Opus 5.5 6c7cc2c5d6 fix(native): do not spend a recovery attempt resuming a cleanly drained run (#19625)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs have an execution recovery budget of three provider
attempts, so a run that keeps failing stops retrying
> - A graceful shutdown (deploy or SIGTERM) drains native runs: it
suspends them for reattachment by the next server
> - When the runner did not survive, the next boot resumed the turn and
charged one attempt
> - Restarts that the run did not cause used up its budget, so recovery
stopped and the task needed a manual Retry
> - This pull request does not charge an attempt for resuming a run that
a graceful drain suspended
> - The benefit is that deploys and graceful restarts no longer exhaust
a healthy run's recovery budget

## Linked Issues or Issue Description

**What happened?**
In restart-chaos testing, native runs reached
`execution_recovery_budget_exhausted` (3/3) only because of server
restarts. In one wave, two restarts crossed each of two runs. In a
second schedule (K1, then K2 when ready, then K2 again), each drain
correctly suspended the local ACPX Claude run, yet the fourth boot
blocked it with `native_restart_recovery_blocked`. Every resume after a
drain was classified `resume_dead_runner` and charged an attempt
(`nextNativeProviderAttempt` in `native-restart-recovery.ts`, applied by
the executor's execution claim).

**Expected behavior**
A restart that the run did not cause should not consume its recovery
budget. A graceful drain records `restart_suspended` and
`awaiting_runner_reattach`. The resume that follows should keep the
attempt count.

**Paperclip version or commit**
`master` at `4ef3fa4271`.

**Steps to reproduce**
Start a native local run. Send the server SIGTERM three times while the
run is active, with a full restart each time. The third resume is
blocked with `execution_recovery_budget_exhausted`.

## What Changed

- `suspendedByCleanDrain()` in `native-restart-recovery.ts` recognizes a
run whose most recent recovery claim is older than the drain's
`restart_suspended` entry. Ownership waits and deferred blocks between
the drain and the next claim do not erase it. The next claim consumes
it.
- A scan that waits for the old controller to exit (`awaiting_evidence`)
records one history entry per reason, so repeated scans cannot push the
drain record out of the bounded history.
- Restart claims carry `chargesProviderAttempt`. It is `false` for a
claim that follows a clean drain.
- `nextNativeProviderAttempt()` takes that flag. The executor passes it
when it takes the execution lease, so a drained resume keeps the current
attempt.
- The first execution is always counted: a run drained at attempt 0 (no
execution claimed it yet) still charges its first provider start.
- A run drained during its third attempt may continue that attempt. The
local resume and remote bootstrap gates skip the `>= 3` exhausted check
only for a non-charging resume, and the executor still refuses a fourth
attempt.
- A crash restart (no drain record) still charges one attempt.
Reattachment to a live runner still charges none.
- `doc/execution-semantics.md` states the rule next to the three-attempt
budget.

## Verification

- New test in
`server/src/__tests__/heartbeat-native-restart-suspension.test.ts`
(embedded Postgres, real heartbeat drain and restart recovery):
- Red before the fix: the claim after the drain had no
`chargesProviderAttempt: false`.
- Green after the fix, for drained attempts 0, 1 and 3: the crash claim
charges (`true`). After the drain, a controlled backend lets the
executor take its execution lease and records the saved
`native_run_finalizations.attempt` at provider dispatch: 1, 1 and 3.
Attempt 3 is claimed instead of blocked.
- Red at the executor: when the executor ignores the flag, the drained
attempt-1 resume saves 2.
- Ownership-wait case: the drained controller (the test process) is
still alive, so two scans wait. The history keeps `restart_suspended`
followed by one `awaiting_evidence` entry. After the controller is gone,
the claim does not charge, and attempt 3 continues.
- Classifier cases (local resume and remote bootstrap): attempt 3 after
a crash is still `execution_recovery_budget_exhausted`. Both new cases
were red on the previous revision.
- `heartbeat-native-restart-suspension.test.ts` 12/12,
`native-runner-restart-recovery.integration.test.ts` and
`native-runner-ownership.test.ts` 94 passed.
- `tsc --noEmit` for `server` passes.

## Risks

- A run that itself makes the server shut down gracefully, again and
again, would no longer be stopped by this budget. Graceful shutdowns are
operator or deploy actions, so this is unlikely. A crash loop (SIGKILL,
OOM) still charges an attempt on every restart, and a resumed turn that
fails still goes through the existing failure and replacement budget.
- This changes only the attempt count. Ownership checks, checkpoint
verification and the exhausted gate are unchanged.

DottaandPaperclip 56c2b28c04 Settle saved monitor results after a newer user request (#19644)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native results must finish their durable finalization before later
work can reuse a saved workspace.
> - An accepted result can wait on a monitor while its workspace files
are recovered.
> - A newer user request can replace that old wait before finalization
resumes.
> - The old finalizer then reports lost monitor authority and blocks the
saved-workspace lineage.
> - This pull request proves the newer user request and settles only the
old result bookkeeping.
> - The benefit is released recovery work without replaying an old turn
or changing the current request.

## Linked Issues or Issue Description

Refs #17641 and #16975.

**What happened?**

An older successful native result has saved files and a server-issued
monitor receipt. Its task is now blocked after a newer user-comment
continuation failed during preparation. The old coordinator stays in
retryable_failure with monitor_wait_authority_lost. The retained
allocation ownership check correctly refuses the unresolved predecessor,
so later file recovery also stays held.

**Expected behavior**

The normal finalizer can settle the old accepted result when exact newer
user-request evidence proves the old wait is superseded. It must
preserve the current task, user input, ownership, schedule, accepted
result, and attempt history. It must not start provider work or publish
the old wait summary.

**Steps to reproduce**

Create an accepted successful monitor result and mark workspace
finalization successful. Leave the task blocked. Record a newer
canonical user comment and its ordinary user wake, either queued or
consumed by a same-task continuation that retains the exact comment
revision and source-run lineage. Call the real native finalizer. Before
the repair, both cases remain retryable_failure instead of settling.

**Paperclip version or commit**

e482f0f632, before this repair.

## What Changed

- Add a company-scoped passive supersession proof in the native monitor
owner. It applies only when the old wait is not currently eligible. The
proof binds the old accepted result and monitor receipt to a newer
canonical unedited user comment and matching user wake. Admitted
successors must retain the exact task, comment revision, and source
lineage.
- Recheck the proof under the existing task transaction, with
nonblocking shared locks on the comment and wake; contention uses the
existing status-race retry path. Commit a preserve decision with no
effects. Keep normal monitor authority, Stop, workspace finalization,
and retained-allocation guards unchanged.
- Add real PostgreSQL coverage for queued and consumed input, current
successor ownership, newer schedules, immutable accepted results,
attempt history, foreign/missing/cancelled evidence, and changes before
commit. Real scheduler ticks create no old monitor wake.
- Include the present superseding proof in the existing assessment
identity. The old failed assessment and decision stay immutable, while
the new decision gets its own assessment. Absent proof keeps the
existing fingerprint unchanged.
- Document passive finalization after a newer user request.

## Verification

- Behavioral RED before production edits: two real PostgreSQL finalizer
cases returned monitor_wait_authority_lost/retryable_failure instead of
settling after a newer queued or consumed user request. Initial
interrupted imports and rejected database setup were not counted as
behavioral failures.
- Additional real-boundary RED: the normal finalization reconciler
reconstructed both persisted errors but failed on
status_decisions_company_assessment_uq because the changed proof reused
an older assessment identity. The owned PostgreSQL log confirmed the
constraint. Including only the present proof in the existing fingerprint
makes both reconciler cases pass while old assessments and decisions
remain immutable.
- Review RED: real comment-row and wake-row contention produced
side_effect_planning_failed. A test-local 100ms lock timeout bounds this
diagnostic. Nonblocking proof locks and `55P03`→NativeStatusRaceError
safely defer both cases, preserve current state, and commit after the
original lock owner releases. Both regressions pass without weakening
the production lock or authority checks.
- Final local GREEN at `0c40331d8d7f587c9a532fbc51d358bfacd1bd46`: five
files, 111 passing tests (126.17s), including all 54 saved-monitor
cases, actual persisted-error reconciliation with an absent retry
deadline and older boot identity, the status
arbiter/task-monitor/terminal-status suites, and six model fixtures.
Current requests, schedules, holds, accepted results and prior
assessments/decisions remain unchanged; normal attempt increments and
idempotent repeat are asserted. Real scheduler ticks create no old
monitor wake.
- All seven server typecheck layers, module-boundary and whitespace
checks pass at the final inputs. Required preflight passes in 15.348s.
No new code comments were added. Local environment: macOS arm64, Node
26.4.0, pinned pnpm 9.15.4, Vitest 5.0.3, owned disposable PostgreSQL 18
with bounded 1GiB tmpfs; no shared Docker data was pruned.
- [Final-head
CI](https://github.com/paperclipai/paperclip/actions/runs/42311889918):
59 successful checks,three intentional skips,one neutral optional
review,zero failed or pending checks. Required E2E and verify aggregates
pass. Greptile reviewed this exact head at 5/5 with no unresolved
findings.
- The [original support
job](https://github.com/paperclipai/paperclip/actions/runs/42311889918/job/128217026059)
passed 6849 assertions and hit one 30000ms timeout in an unchanged
private-evidence fixture. The exact case passed locally; all 41 cases
passed together (42.79s). The [identical-input sibling CI
control](https://github.com/paperclipai/paperclip/actions/runs/42311878548/job/128216598362)
passed all 6850 assertions and the 41-case file in 5.417s. Exactly one
targeted replay was authorized and dispatched after workflow completion
and ordinary quota reset, preserving the other 57 passing checks.
[Replay
job128227417618](https://github.com/paperclipai/paperclip/actions/runs/42311889918/job/128227417618)
passed 323 files/6850 assertions with four existing skips; the 41-case
file passed in 5.665s. No fixture, source, assertion, timeout,
credentials or full workflow was changed/replayed. The original timeout
remains recorded; its precise host-level cause was not determined.
- Inherited baseline failures were handled through normal integration of
existing #19610 (model expectations), #19627 (deterministic Slack
deadline fixture), and #19646 (current trusted Runner lane flags). All
four exact lane-command dry runs and the lane-inventory regression pass.
No force push or new production patch was used for those failures.
- Hosted recovery remains pending deployment and acceptance through the
normal pipeline; these checks do not claim the live task has already
recovered.

## Risks

- The new proof must remain passive. It cannot grant execution or
restore an obsolete task state. Missing or changing proof leaves the old
result held.
- The query reads only the same company's task and agent, with requests
newer than the old completion time and one selected result. It runs
during active finalization and adds no timer or idle polling.
- Edited comments, cancelled wakes, foreign lineage, source Stop, and
workspace failure are refused. Existing workspace snapshot, stop, and
handoff checks still own physical file recovery.
- Hosted acceptance remains pending deployment through the normal
pipeline.

## Model Used

- OpenAI Codex (GPT-6 family), with code execution and repository tools.
The runtime does not expose the exact serving model identifier or
context window size.

DottaandClaude Opus 5.5 f4b19e4231 fix(runner): finalize a durable proposed result when restore loses its Codex turn (#19658)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native Codex runs survive control-plane restarts: runnerd restores
the provider conversation, and the control plane continues the task from
its checkpoint
> - A hard kill can land after the agent proposed its result
(`run.result.proposed`) but before the provider turn ended
> - The restored runner then proves that the turn ended with the
accepted result. It records `session.reconciled` and `run.terminal`, but
no provider turn terminal
> - The Codex recovery read did not see that turn as ended, so recovery
failed with "persisted active turn … is missing from thread/read".
Retries ran out, and the Retry re-ran finished work
> - This pull request lets recovery settle that turn with its durable
result
> - The benefit is that a task that already finished its work continues
to finalization after a restart, instead of failing and redoing the work

## Linked Issues or Issue Description

Refs #19525, #19591, #19539, #19501

**What happened?**
In a restart storm, a native Codex task (B1) proposed a complete
`paperclip.run_result.v1` with passing tests. The control plane accepted
the completion tool call. About 9 s later, a K1 (SIGKILL and restart of
the control plane) killed the controller, runnerd, and the Codex
app-server. After startup, `resume_dead_runner` resumed the same run two
times. Each resume spent about 25 s in `runner.session.startup` and
failed with `native_session_recovery_failed: HarnessReconciliationError:
persisted active turn <id> is missing from thread/read`. Then
`native_session_retry_exhausted`, replay was blocked
(`preserve_without_replay_v1`), and the run ended
`native_session_interrupted`. The task needed a Retry, which re-ran the
finished work.

**Steps to reproduce**
1. Start a native Codex task through runnerd.
2. Let the agent call `paperclip_finish`, and let Paperclip accept the
result.
3. Kill the controller, runnerd, and Codex before the provider turn
ends.
4. Let restart recovery resume the run.

Durable evidence from the kept instance:
- The run events have `run.result.proposed` for the turn, then a
`completion.tool_accepted` span, then the kill.
- The saved checkpoint has `activeTurnId` set to that turn and
`semanticResult: null`.
- The Codex rollout on disk does contain the turn. The provider did
persist it.
- The runnerd journal for the first resume has `session.reconciled
{previousProviderTurnId: <turn>, activeProviderTurnId: null}` and then
`run.terminal {turnTerminalState: completed, runTerminalState:
succeeded, reportedWorkDisposition: done}`. It has no `turn.*` event for
that turn. The runnerd Codex provider state shows
`completedTurnAuthoritative: true` and `completedProviderTurnId:
<turn>`.

**Expected behavior**
Recovery finalizes the accepted result. It does not re-run the task.

**Actual behavior**
The runnerd Codex transport builds the recovery `thread/read` reply from
runnerd's journal. It looked only for
`turn.completed|failed|interrupted|cancelled` events that name the turn.
Runnerd's "turn ended with an accepted result" branch
(`provider_backend.rs`, `recovered_turn_ended_with_result`) emits only
the reconciliation and the run terminal. So the reply omitted the turn,
and `CodexHarnessSession.reconcile()` threw at
`codex-harness-session.ts:796`. The second resume read the same journal
and failed the same way.

## What Changed

- `runnerd-codex-transport.ts`: a new `runnerdRecoveredTurnTerminal`
helper selects the terminal for a restored turn. A provider `turn.*`
terminal that names the turn wins, as before, with its cause. A
`run.terminal` that follows a `session.reconciled` that names the turn
as the ended previous turn (no active turn, no later `turn.started`) now
also settles that turn, with the run terminal's `turnTerminalState`. The
`thread/read` wait loop uses this helper.
- `codex-harness-session.ts`: `reconcile()` now settles a checkpointed
active turn that provider history no longer contains when the session
holds the semantic result that this exact turn proposed (`resultTurnId`
equals the turn). Recovery restores that result from the durable
`run.result.proposed` event. Without such a result, a missing turn still
fails closed.
- `codex-harness-session.ts`: the same rule applies when the restored
runner reports that turn `failed` with `provider_turn_lost_on_restore`.
This happens when the runner cannot prove the accepted result itself.
Later recoveries keep the settled outcome. Without a held result, a
restore-lost turn keeps its existing failure and same-conversation
continuation.
- `fake-codex-app-server`: a test-only `--hold-after-terminal-result`
flag keeps the turn open after an accepted completion report.
- `doc/execution-semantics.md`: one additive paragraph on this recovery
rule.

## Verification

- Red before the fix, real `paperclip-runnerd` and fake Codex: `pnpm
--filter @paperclipai/paperclip-runner exec vitest run
src/live/runnerd-restart-continuation.test.ts -t "durable proposed
result"` failed with `native_session_recovery_failed:
HarnessReconciliationError: persisted active turn provider-turn-1 is
missing from thread/read` at `native-session-runtime.ts:2267`. This is
the same stack as the incident.
- Green after the fix: the run finalizes on `provider-turn-1` with the
proposed result and `runTerminalState: succeeded`. It has no
`session.failed` or `turn.failed`, and Codex received only one
`turn/start` (no re-run). With the transport fix alone, the test passes
in about 5 s. With only the session fix, it also passes (about 30 s,
through the 5 s read wait).
- Driver red/green:
`src/drivers/codex/codex-app-server-driver.recovery.test.ts -t "missing
persisted turn"`. The settle case failed before the fix (`recovered:
false`) and passes after it. The guard case (the held result belongs to
another turn) still fails closed. The existing "fails recovery
explicitly when the persisted active turn is missing or replaced" test
still passes.
- Driver red/green for the restore-lost case: `-t "restore-lost turn"`.
The held=true case failed before the fix and passes after it. The
held=false case still maps `turn.failed` with the lost cause.
- Transport unit test: `runnerd-codex-transport.test.ts -t "reconciled
result terminal"` covers the run-terminal rule and its negative cases.
- Suites: `src/drivers/codex/`, `src/native-session-runtime.test.ts`,
`src/backends/`, `src/live/runnerd-restart-continuation.test.ts`, and
`src/live/runnerd-codex-transport.test.ts` pass. Some load-sensitive
tests time out at host load 25–30 and pass when rerun alone. The two
`proves local suspension after an event backlog … (1024 suffix deltas)`
cases also time out on unmodified master.
- `pnpm --filter @paperclipai/paperclip-runner typecheck:typescript`
passes.
- Live chaos replay with real Codex: K1 0–3 s after
`run.result.proposed`, 3/3 PASS (R1). Each case resumed the same run,
which ended `succeeded`. No Retry was needed and no work was re-run.
Details are in the comment below.

## Risks

- The transport rule accepts a run terminal only directly after
runnerd's own reconciliation that names the ended turn with no active
turn. Runnerd emits that pair only after it restored the conversation
and proved the turn ended. A provider turn terminal still wins. Other
run terminals do not settle a turn.
- The session rules use only a result that Paperclip already holds for
the exact turn. The control plane accepted that result before the kill.
A later provider terminal for that turn cannot change the outcome. The
finalizer can already interrupt a provider after an accepted result.
- A missing turn without a durable result still fails closed. Its
outcome is unknown, and the existing Retry stays available.
- No profile, schema, pack contract, or database changes. The Rust
change touches only the fake Codex test binary.

DottaandPaperclip 9197abf673 fix(native): preserve controller state when remote archiving fails (#19663)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native continuity replacement must preserve the state needed to
recover saved work.
> - The current replacement moves local controller files before it knows
whether the remote archive succeeded.
> - A remote failure then leaves the local controller without its
recovery files.
> - This pull request confirms the remote archive before it moves those
files.
> - A user turn that never started can use the existing bounded Retry
path after verified preservation and cleanup.
> - The task retains its saved work and can continue once under current
user authority.

## Linked Issues or Issue Description

Refs #19638, #19547, #19399 and #19659.

The prerequisite #19638 merged as
`0819f4ea78dd37fba87341b314be9dac078c1410`. This PR now targets master.
A normal dependency integration at `febed950f4` keeps only the six-file
archive repair in the PR diff. Fresh master-based CI and review are
required before merge.

**What happened?**

A native continuity replacement moved its local controller journal and
provider checkpoint. The following remote archive failed. A later
recovery attempt could no longer read the local recovery files. The
first-attempt failure also had no normal Retry receipt for the saved
user turn.

**Expected behavior**

A failed or timed-out remote archive retains the local recovery files
and starts no replacement provider. A user turn that has not started can
request one normal Retry. The existing user, provider-turn, Stop,
preservation, cleanup, budget and approval gates remain in force.

**Steps to reproduce**

1. Keep a local controller journal and provider checkpoint for a
retained remote conversation.
2. Request continuity replacement and fail or time out the remote
archive command.
3. Check the local controller files before any later recovery.
4. Settle the native failure under a current user wake and recover the
saved workspace.

## What Changed

- Confirm remote continuity archiving before moving the local controller
state.
- Add the exact remote archive failure to the shared bounded user Retry
admission from #19638.
- Verify failed, timed-out and successful archive ordering with real
local files.
- Verify ordinary failure settlement and saved-file recovery produce one
fresh successor. Keep Stop, system wake and unsettled-provider holds.
- Document the file preservation and Retry contract.

## Verification

- RED: failed and timed-out remote archives removed the local controller
files. Reading those files failed with ENOENT. The saved-user Retry
request returned false instead of true.
- Initial archive unit verification: eight cases passed, including the
three archive outcomes and five existing Cloud archive safety cases.
- Initial stacked revision: `9104ee399b`, based on #19638 at
`d22d8f9d5ee3dc36550a94d55c1d8376f3b9aab2`.
- Final master-based revision: `febed950f4`. All 13 affected cases
passed across three Vitest files after dependency integration. They
include the seven-mode real PostgreSQL completion case, saved-file
successor and negative-hold cases, and real-file archive outcomes. All
seven server typecheck layers passed again. Module boundary, whitespace
and added-code-comment checks passed. All required CI passed on this
exact head. The final snapshot has 59 successful checks, three intended
skips, one neutral result, and no pending or failed checks. Current-head
Greptile and the independent review are both 5/5, with no open findings.
- Final local revision: `9104ee399b`, macOS ARM64, Node 26.4.0, pnpm
9.15.4 and embedded PostgreSQL. The three real-file archive outcome
cases passed. The real PostgreSQL completion test passed all seven
internal scenarios, including archive failure, prior provider activity,
system wake, Stop before and after terminal settlement, and stale
runtime promotion. Own Runner/shared/SDK builds and all seven server
typecheck layers passed. Nine saved-work continuation and negative-hold
cases passed. They verify exported file contents, one user-attributed
fresh successor, idempotent hooks, no second automatic chain, and
first-use manual Retry for held cases.
- `node scripts/check-module-boundaries.mjs`, whitespace checks and the
added-code-comment audit passed.
- Focused commands from `server/`: Vitest with `-t 'retains the local
controller checkpoint until remote continuity archiving succeeds'`; `-t
'replays saved user intent through normal Retry'`; and `-t 'continues a
user turn once|does not continue automatically'`. PostgreSQL cases used
a fresh local cluster and a 120-second setup hook budget. Application
timeouts were unchanged.
- The initial stacked head passed all test, build, typecheck and E2E
jobs. Greptile and the independent review both scored it 5/5 with no
findings. These results do not replace the fresh master-based
qualification now running.

## Risks

- A remote command can fail after it changed remote state. This change
retains local evidence in that case. It does not claim a distributed
atomic transaction.
- The exact archive error can request one normal Retry only under the
existing saved-user admission. The normal path must prove stop, saved
files and cleanup before a successor starts.
- The protected launch-argument rejection remains enforced. Its exact
hosted argument difference was not available through ordinary access.
#19659 separately addresses a saved-thread feature-policy argument
difference. This PR preserves local archive evidence and does not claim
direct hosted verification of that primary cause.

## Model Used

OpenAI GPT-6 family through Codex, with reasoning, tool use and code
execution. The model is inherited; no override was used. The exact
serving model ID and context-window size are not exposed by this
runtime.

DottaandPaperclip 0819f4ea78 fix(native): verify controller ownership before retrying saved turns (#19638)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native task turns can keep a provider conversation from an earlier
run.
> - A copied conversation checkpoint names the new run before its
controller has attached.
> - A failed attachment can make recovery treat that copied identity as
current execution authority.
> - The current run needs its own durable controller checkpoint, or a
valid staged attachment, before exact resume.
> - This pull request checks that ownership and uses the normal Retry
path to continue a saved user turn after verified cleanup.
> - The task can continue once with its saved work and history.

## Linked Issues or Issue Description

Refs #19399 and #18860.

**What happened?**

A new user comment resumed a completed native conversation. The retained
runner process was gone before the new controller attached. The new run
still had a copied provider session ID. Recovery selected exact resume
for that new run and then failed its unchanged owner and lease checks.
Ordinary first-attempt failure settlement also omitted the saved-user
Retry handoff that restart recovery already uses.

**Expected behavior**

Exact resume requires current controller evidence. A saved user turn can
request one normal Retry after this infrastructure failure. The normal
path must verify provider stop, saved files, current user authority and
all execution gates before it starts a fresh session.

**Steps to reproduce**

1. Finish a native warm run and retain its provider checkpoint.
2. Admit a user comment as a new run and copy the provider checkpoint
through the real resume producer.
3. Stop the retained runner before attachment. The real remote process
check reports that the process is not running.
4. Observe that the copied provider ID selects exact current-run resume.
Observe that ordinary failure settlement saves no Retry request.

## What Changed

- Check a bounded encrypted controller header for fenced remote Runner
recovery. Keep local Runner recovery on its existing disk-backed path.
Match the run, conversation and runner identity. Preserve the existing
staged-attachment path.
- Share the existing saved-user Retry admission between restart recovery
and ordinary terminal native settlement. Keep its exact infrastructure
errors, user wake, comment, provider-turn and retry-chain checks.
- Add real PostgreSQL and stopped-process regressions. Verify malformed
and foreign checkpoint holds, current-owner resume, user authority and
Stop. Verify saved-file recovery creates one fresh-session successor.
- Document the ownership and Retry contract.

## Verification

- RED: the real checkpoint rebind producer and stopped-process check
selected exact current-run resume without a current controller
checkpoint.
- RED: ordinary settlement created zero Retry receipts for the real
native failure code; expected one.
- Review RED: a real current local controller file existed with no
database checkpoint rows. The initial gate returned ambiguous state. The
fix takes a required trusted execution-target kind and applies the
database requirement only to the remote persistence path.
- Initial local revision: `3662055880ccf8e09c3c50a340897e16c78627e7`,
macOS ARM64, Node 26.4.0, pnpm 9.15.4, embedded PostgreSQL.
- Initial server Vitest: 42 selected cases passed across controller
recovery integration, remote restart adoption, ordinary run completion
and retained workspace recovery. The cases cover the stopped-process
producer, current/foreign/malformed ownership, automatic user
continuation, Stop, unsettled turns, system wakes and a manual Retry on
first use.
- `pnpm --filter @paperclipai/server typecheck`: passed with this
worktree's Runner, shared and SDK builds and all seven server layers.
- `node scripts/check-module-boundaries.mjs`, whitespace checks and the
added-code-comment audit: passed.
- Review correction: `8c795e2e0e44b5209da3e228593c5cd35e948cae`. The
real local/remote controller case passed against a fresh PostgreSQL
cluster. It verifies local disk recovery without database rows, remote
current-owner resume, and remote missing/foreign/malformed holds. Fresh
`node scripts/typecheck-layers.mjs` passed all seven server layers. The
existing offline chat reader now requests metadata only and retains its
full independent native-state safety check.
- A broader local recheck hit PostgreSQL setup/cleanup hook timeouts.
These are retained as failed setup attempts; the fresh-cluster
regression above passed. Required CI supplies broad final-head coverage.
- Settlement-order correction:
`dafb721c3bbb7ae86fbc3c9c6c953ace29ca088b`. The real PostgreSQL
regression first proved both failures: Stop after an already-failed row
created one Retry instead of zero; a DB-native promotion with an old
legacy caller snapshot created zero instead of one. All six settlement
scenarios now pass. The hook requires the local failed outcome and the
canonical settled native row. Fresh seven-layer server typecheck passed
again.
- Required shared fixture base integrated at
`d22d8f9d5ee3dc36550a94d55c1d8376f3b9aab2`. The six runner-skills
fixture cases and all seven server typecheck layers passed. Required CI
passed for this head:
[workflow](https://github.com/paperclipai/paperclip/actions/runs/42309419592),
including all server layers, tests, build, Runner verification and E2E.
The final snapshot has 57 successful checks, three intended skips and
one neutral result. Current-head Greptile is 5/5; both concrete review
threads are resolved. The independent re-review ended without a final
response; its prior Stop finding has a real RED/GREEN repair.

The focused command was run from `server/`:

```sh
../node_modules/.bin/vitest run --config vitest.config.ts src/services/heartbeat/run-completion.test.ts src/services/native-runtime/native-controller-recovery.integration.test.ts src/services/native-runtime/native-session-executor.test.ts src/services/workspace-recovery.test.ts -t 'replays saved user intent|does not assign current-run resume authority|remote controller restart adoption|continues a user turn once|does not continue automatically'
```

## Risks

- A terminal failure of a fenced Runner adds one exact-run header read.
The read selects one encrypted header and limits inspection to 1 MiB.
Invalid or missing ownership evidence stays held.
- Saved user input can request one automatic Retry. It uses normal
preservation, current authorization, budget, approval, Stop and cleanup
gates. Unsettled provider turns and system wakes do not start an
automatic successor.
- This PR changes no provider process, credential, model or lease

DottaandPaperclip c9391720a1 fix(heartbeat): send saved follow-ups after task completion (#19600)
## Thinking Path

> - Paperclip manages agents and their work.
> - Task messages remain in a durable queue while an earlier run saves
its result.
> - That result can mark the task done before the user sends the saved
messages.
> - Send records current user intent, but its wake guard allowed only
active task states.
> - The old queue therefore remained pending with an obsolete
finalization message.
> - This change admits that exact Send receipt and reopens the task
through the issue service in the successor transaction.
> - The agent can receive the saved input once while the completed
result remains unchanged.

## Linked Issues or Issue Description

**What happened?**

Send on a saved message can leave the message queued after its native
predecessor succeeds and commits. The old wait message remains visible.
Allowing admission alone also fails: continuation construction rejects a
task that remains done.

**Expected behavior**

Explicit Send must deliver the saved input once through normal
admission. It must retain the previous run and its result.

**Steps to reproduce**

1. Save a follow-up while a native run finishes its result.
2. Let that run succeed, commit its accepted result, and mark the task
done.
3. Send the saved follow-up. Before this change, the receipt stays
deferred.

Related public work: Refs #19542. That change selects recovered
workspace files. This change handles the later saved-message admission.
Refs #19602 for the independent workflow fixture repair required by CI.

## What Changed

- Allow the exact explicit Send wake guard to accept a done task. Keep
automatic recovery and cancelled task guards unchanged.
- Reopen the task through the company-scoped issue service after
admission gates pass. Commit reopening, queue consumption and the
successor together. Publish the audit after commit.
- Add a native succeeded/committed predecessor regression with unchanged
saved work and one successor after two resume calls.
- Verify real heartbeat startup under the clicking operator. Keep
automatic input, cancelled tasks and paused agents held.
- Check workspace preflight for the prospective reopened task. Use the
normal company-scoped transition if preflight blocks a done task, so its
completion metadata is cleared.
- Check a successful native predecessor for its committed accepted
result, current ownership and pending cleanup. Keep approvals and
questions effective even without a recovery action.
- Document the saved Send contract and update the queue test dependency.

## Verification

- Final merge qualification for
`675914f0fa9b5eb1d2c9c8fcd448e0669d0c4836`: all 56 applicable status
checks pass, with no pending or failed checks. [Final
CI](https://github.com/paperclipai/paperclip/actions/runs/42307623559)
includes typecheck, build, all applicable test and E2E shards, and
aggregate verification. Current-head Greptile is 5/5; all five review
threads are resolved. Any paused or queued application review is not
claimed as a new completed review.

- Final base qualification at
`675914f0fa9b5eb1d2c9c8fcd448e0669d0c4836`: official preflight passes
(1.5s); all six integrated model-normalization cases pass (19.07s); both
affected test typecheck layers pass. The integration changes no
production server/shared/Runner/adapter inputs, so the preceding 12-case
Send proof, two ordinary status guards, and unchanged production
typecheck layers remain applicable. Fresh final-head CI supplies broad
coverage.

- New review regression: both failed and cancelled native predecessors
on a task manually marked Done fail before the repair with
`continuation_task_ownership_changed` through real
`resumeQueuedCommentInterrupt` admission. At
`bfb0eff7941090ac3ac43ce4366ba2e3d46612e9`, all 12 affected
Send/source/cleanup/workspace/decision cases pass (246.80s), ordinary
Done/cancelled rejection cases pass (2; 100.31s), and all seven server
typecheck layers pass. History validation uses the prospective reopened
status only for an already-verified explicit native Send. No status is
changed during a dry run.
- Prior `e64e4bb1` CI passed the affected serialized server suites,
including the complete saved-message route suite, typecheck and build.
General server shard 4 still failed two unrelated stale default-model
expectations (`gpt-5.6-sol` versus the new `gpt-6.1-sol` default). The
equivalent repair has already merged in #19610 as
`8621bcf53ee2e4bbefb7d193add42dd544ca06e8`; the separately prepared
#19645 is closed as superseded. This source fix does not weaken or edit
those assertions.

- Original RED: the committed-source and completed-task startup cases
left the saved receipt deferred.
- Review RED: Done plus an unrunnable isolated worktree created one
successor instead of zero. A successful committed predecessor with
pending lease cleanup also created one instead of zero. The new
Done-to-blocked path retained stale completion time. Pending approvals
and questions each allowed a successor. All failures were captured
before their respective repairs.
- Integrated production revision
`99018264dd1ef002ff3500378184bcd167d9206b`: 417 affected cases pass
across the complete native continuation, responsible-user startup, and
workspace preflight suites (386 + 18 + 13). These include the original
successful startup case and six cleanup/finalization faults that hold
the exact saved receipt until settlement, then deliver it once.
- `pnpm --filter @paperclipai/server typecheck` passes all seven layers
on that integrated head, including the local Runner/SDK dependency
build. Module-boundary, whitespace, and added-code-comment checks pass.
- Normal master integrations preserve branch history. No force push or
assertion weakening was used. Fresh CI and automated review are running
on `675914f0fa9b5eb1d2c9c8fcd448e0669d0c4836`, which normally integrates
the already-merged #19610 fixture repair after the reproduced inherited
CI failure.
- The earlier CI attempt failed in five unchanged workflow fixture cases
because IMAGE_ONLY was unset. The merged #19602 repairs that fixture. A
later inherited duplicate default in that independent fixture has a
separate repair; this PR does not edit it.
- Follow-up route-fixture RED: three existing native queue delivery
cases failed because their fixture marked a run successful without an
accepted result or committed finalization. The same three cases pass
after the fixture records the complete native success contract (42.08s);
delivery assertions and production gates are unchanged. The affected
test-tree TypeScript layer also passes. The full route run passed all
119 assertions but failed its 30-second database teardown hook, so it is
not recorded as a suite pass. That result is retained. One unchanged
bounded rerun was stopped after more than 15 minutes without a final
verdict; it is inconclusive, not a pass.
- Final integrated head `e64e4bb1`: all 13 focused route and
completed-task admission cases pass across two real-PostgreSQL suites
(188.95s), including the three repaired route fixtures and every new
cleanup/finalization/decision hold. Fresh preflight passes; all seven
server typecheck layers pass. Required final CI supplies the broader
route and server coverage.
- These tests use real PostgreSQL and normal admission, cleanup, queue
consumption, and startup services. The startup suite controls the
provider boundary. Hosted provider acceptance remains pending normal
deployment.

## Risks

- Explicit Send can reopen a done task. This is limited to its validated
saved receipt and current assignee. A cancelled task remains held.
- Reopening uses the existing company-scoped issue transition and shares
the successor transaction. A failed admission does not reopen the task.
Provider Stop, workspace, approval, pause and budget checks retain their
existing owners.
- Cleanup and pending decisions retain the done task and saved receipt.
An unrunnable workspace uses the existing blocked-task diagnostic. No
schema or runtime package changes.

## Model Used

- OpenAI Codex, GPT-6 family; exact serving snapshot/context window not
exposed; repository analysis, code editing, tool execution.

DottaandPaperclip 795c3c4c1d fix(recovery): continue saved input after historical retry pause (#19576)
## Thinking Path

> - Paperclip manages work performed by AI agents.
> - Its scheduler parks work when another run holds a shared workspace.
> - A pause can refuse the scheduled retry before provider dispatch.
> - Older schedulers recorded that refusal in the run log without a JSON
marker.
> - After the pause was released, a saved user message could remain held
for execution recovery.
> - This change verifies the original refusal and parent workspace-wait
proof before admitting one continuation.
> - Existing execution, Stop, budget, approval, and workspace guards
remain in force.

## Linked Issues or Issue Description

Refs #19466, #19552, #19580, #19602.

**What happened?**

A saved user message remained deferred after a pause was released. Its
source was a never-claimed workspace retry. The historical source had an
`issue_paused` error and no JSON cancellation marker. The continuation
proof accepted only a different system-cancellation shape.

**Expected behavior**

The normal saved-message worker admits the existing input once when
trusted scheduler evidence proves no provider dispatch occurred and
current admission gates permit work.

**Steps to reproduce**

1. Record a host-certified pre-provider workspace wait and its scheduled
retry.
2. Let the real scheduler refuse promotion under an active task pause,
including after the user presses Retry Now.
3. Keep the historical run-log-only cancellation shape, then release the
pause.
4. Run concurrent normal saved-message recovery scans.

**Paperclip version or commit**

The regression fails on master `f0006c7783`. It leaves zero queued
successors. The branch now normally integrates the fixture repairs in
#19602 and #19628.

## What Changed

- Accept the historical cancellation shape only when a trusted system
lifecycle warning records the exact scheduler pause refusal. A prior
Retry Now event does not invalidate that proof.
- Bind the event to a released same-company pause and its task
membership.
- Reuse the existing parent workspace-wait certificate,
no-provider-output checks, and retained-execution rejection.
- Preserve historical cancellation records and consume the existing
saved input through normal admission.
- Document the contract and add real PostgreSQL coverage using actual
scheduler suppression and pause release.

## Verification

- RED: the real scheduler suppressed the retry under a pause. After
release, two normal recovery scans left zero successors.
- GREEN: the same path creates one successor and coalesces the original
saved request.
- All 389 tests in the complete native continuation suite pass before
the final base update. The only changed continuation source from master
is the separately merged one-line repair in #19552.
- Fourteen focused cases passed at
`2aaeb50f78ba0a22809ab96a00076ce50fcea559`, including a parent pause
covering a child task. Thirteen cases also passed before the base
update. They cover the normal path and missing event, wrong task,
missing membership, active or mistimed pause, provider activity,
retained lease, operator Stop, and invalid ancestry.
- The earlier seven-layer server typecheck passed after building this
worktree's Runner and SDK dependencies. The current review fix passes
the exact CI test-layer typecheck. Fresh required CI will supply
current-head source coverage.
- The first sandboxed database run could not bind loopback. A later
fresh dependency install omitted native PostgreSQL library symlinks and
failed before executing tests. The package's own postinstall hydration
repaired that setup. Previous-head verification passed all 14 focused
cases at `2aaeb50f78ba0a22809ab96a00076ce50fcea559`.
- Module-boundary and whitespace checks pass.
- Commands: `cd server && pnpm exec vitest run
src/services/explicit-native-continuation.test.ts`; `pnpm --filter
@paperclipai/server typecheck`.
- Environment: macOS arm64, Node 26.4.0, pnpm 9.15.4, real local
PostgreSQL.
- Previous head `2aaeb50f78ba0a22809ab96a00076ce50fcea559` had Greptile
5/5 and 56 passing checks, with three skipped. A later advisory review
found the Retry Now event-order case. Those checks do not qualify the
new head. Hosted recovery remains unverified.
- Review RED: the real `retryScheduledRetryNow` producer wrote
lifecycle/info at sequence 1 and the exact pause warning at sequence 2.
After real hold release and two concurrent normal queued-message scans,
both task-rooted and parent-rooted cases produced zero successors
instead of one. Both failed before the production change (17.24s).
- Review GREEN: all 17 focused cases pass at
`f38e9934b8ce3f7ddfb23eaa0f979c3f44e7a990` (4.74s). The previous 14
cases remain covered. Two new cases use the real Retry Now producer, and
one new case rejects contradictory provider execution evidence. No
pause, membership, timing, ancestry, output, retained-execution, or Stop
check was removed.
- Current focused command: `pnpm exec vitest run
server/src/services/explicit-native-continuation.test.ts -t 'historical
pause|Retry Now pause history' --fsModuleCache`. Current test-layer
typecheck: `cd server && node ../node_modules/typescript/bin/tsc
--noEmit --project
node_modules/.cache/paperclip-typecheck/tsconfig.tests.json --pretty
false`. Both pass.
- Final-head verification: all 17 focused cases passed again at
`c88687d69f2c87fe1b81b5fffd670e3cf26a884d` (8.00s). The prior exact CI
test-layer typecheck qualifies the unchanged typed logic; fresh CI
supplies broader final-head coverage.
- The follow-up commit removes only the new code comments to follow
CONTRIBUTING.md. Recovery and test behavior are unchanged. That revision
had Greptile 5/5 with its actionable review thread resolved. It is
retained as historical verification; current-head qualification is
below.

- The first final-head CI attempt failed in the unchanged CLI company
import/export fixture before assertions: its child server did not reach
the runtime-info health check within 30 seconds. Other suites passed.
The exact fixture passes locally with its original timeout. The single
failed-shard retry passed at the unchanged head, together with its
dependent CI checks. [Original failed
job](https://github.com/paperclipai/paperclip/actions/runs/42279773036/job/128106195975).
No assertion or timeout was changed.

- The independent required Runner support failure reproduced five
`IMAGE_ONLY: unbound variable` errors. #19602 repaired its fixture
inputs and merged as `4d554f08218b04df49ec0f2a0d5c5dfdfaf65660`. This
branch normally merges that master with no conflicts or force push. The
current host-preparation log verifier from #19580 remains intact.
- Final integrated head `ffc9e8d9516343a9823b4b80b5fcfccc548844ba`:
17/17 focused recovery cases pass (12.71s), all nine workflow-target
cases pass through the official Runner Vitest config (1.10s), and all
seven current server typecheck layers pass. Worktree preflight rebuilt
current Runner dependencies and reused the Cargo seed; it completed in
61.3s with Rust debug binaries skipped.
- Prior integrated head `ffc9e8d9516343a9823b4b80b5fcfccc548844ba`
finished with 54 successful checks. Its only code-check failure was a
global unhandled readiness rejection after 2,285 assertions passed in
the server8 shard, plus dependent verify. The real-child race is fixed
separately in #19624; it was not hidden by a rerun here.
- Final normal integration head
`550d1732b6960d6b349d03903f448fa1d71c17f6`: exact 17 paused-retry
lifecycle regressions pass (71.06s), all nine official workflow target
cases pass (2.43s), all seven server typecheck layers pass, and
module/whitespace checks pass. Required preflight completed in 45.641s.
Current preparation-log guards from #19580 remain intact. The diff
against master contains only the original three owner/test/doc files.
- Prior head 550d had two inherited model-default assertion failures
plus a retained-cleanup backlog 15s timeout. The exact unchanged cleanup
case passes locally (41.91s total including DB/hooks); no timer or
assertion was weakened and no old CI job was rerun. The model fixture
repair was independently merged in #19610 at
8621bcf53e.
- Current normal integration head
`14103750d5f26d7f476f937e981e3e45c94054ab`: 17/17 exact lifecycle cases
pass (75.33s), all 6 model normalization cases pass (6.58s), all seven
server typecheck layers and source checks pass. Required preflight
completed in 13.89s. No source guards or timeouts changed during this
integration.
- Current-head CI and Greptile are green. Earlier checks do not qualify
this final integration head.

- Current-head Greptile: 5/5 at
`14103750d5f26d7f476f937e981e3e45c94054ab`, with all review threads
resolved. Required CI passed: 56 successful checks, three intentional
skips, one neutral review status. The separate optional Paperclip review
job remains queued; no open findings.

## Risks

This adds a bounded indexed evidence query for a narrow historical
cancellation shape. Missing or contradictory evidence keeps work held.
It does not replay a provider turn or change current pause, budget,
approval, Stop, or workspace authority.

## Model Used

OpenAI Codex, GPT-6 family, with repository analysis, code editing, and
tool execution. The exact serving snapshot and context-window size are
not exposed in this session.

DottaandPaperclip c09fb60ca6 fix(recovery): retain worker-stop audit in preparation retries (#19612)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Recovery must preserve saved files before it admits another
execution.
> - A failed preparation can need a verified stop of its previous
workspace worker.
> - Recovery keeps that verified stop receipt in the run profile for
audit.
> - The preparation retry guard treats the retained receipt as unknown
execution evidence.
> - This pull request recognizes a valid same-run audit receipt while it
retains all current execution and file checks.
> - A saved Retry can then continue once after recovery completes.

## Linked Issues or Issue Description

**What happened?**

A native preparation failed before provider dispatch. The recovery
worker verified that the previous workspace worker had stopped and saved
its files. The same HTTP Retry stayed deferred because the run profile
retained `nativeWorkspaceOwnerStopProof`.

**Expected behavior**

The saved Retry should continue once after all preparation, stop, file,
ownership, and authorization checks pass. The old run and its audit
receipt should remain unchanged.

**Steps to reproduce**

1. Fail native preparation with a retained remote workspace and no
provider activity.
2. Let the recovery worker acquire the old workspace owner through
verified platform stop evidence.
3. Submit one HTTP Retry and let preservation complete.
4. Observe that the old guard retains the retry hold even after
saved-file verification passes.

**Paperclip version or commit**

Reproduced against `d728be8fbf`. Related work: #18908, #19021, #19026,
and #19466. This change covers the retained workspace-worker stop audit
left by a later repair.

## What Changed

- Add a typed reader for a host-persisted same-run worker-stop audit
receipt. Keep signature and expiry validation at ownership acquisition.
- Recognize only that validated audit field in failed-preparation
settlement. Keep unknown profiles and active owners blocked.
- Exercise real preservation, HTTP Retry delivery, native dispatch,
saved files, accepted results, and task completion. Add malformed,
foreign-run, unstopped-worker, and active-owner cases.
- Document the distinction between retained audit evidence and current
execution authority.

## Verification

- Failing before the fix: the current-worker preservation case passed;
the stopped-worker case produced zero successor runs after the same
Retry, where one was expected.
- Passing after the fix: 47 recovery cases, 10 native
dispatch/preservation cases, and 6 platform-proof tests. The two
preservation success cases overlap between the first two groups.
- Server typecheck passed all seven layers after the final test changes.
The Runner and SDK dependencies were built in this isolated worktree.
- Final comment-free commit `44f8f33f8d917dddb51852283a479786102eab4d`:
a fresh combined run passed all 61 affected cases in 67.92s. Fresh
server typecheck passed all seven layers.
- The earlier `95d0376c` combined run passed 60 cases and hit one
`socket hang up` in the existing `catalog_provider_warning` HTTP test.
That case passed in a bounded isolated run (12.48s), and the final
61-case combined run passed. The socket failure remains recorded as an
intermittent HTTP harness limitation. No retry or weaker assertion was
added.
- Final commit `44f8f33f8d917dddb51852283a479786102eab4d` completed all
required CI gates: 57 checks succeeded, 3 intentional skips, and the
advisory Paperclip review is neutral with a substantive 5/5 verdict.
Greptile is 5/5 and there are no unresolved review threads. [Final CI
run](https://github.com/paperclipai/paperclip/actions/runs/42293625696).
The follow-up commit only removes six new code-comment lines to follow
CONTRIBUTING.
- The native provider and signed platform API are controlled test
boundaries. The tests use real PostgreSQL, recovery, ownership, file
persistence, retry admission, dispatch, and finalization services.
Deployed recovery remains unverified until normal rollout.

## Risks

- The main risk is mistaking an audit receipt for current stop
authority. The reader checks its exact shape and run binding. The
receipt cannot replace stopped leases, saved-file receipts, settled
preparation, current authorization, or the absence of an active owner or
provider evidence.
- The negative matrix runs with the audit field present. Provider
activity, unknown usage, bad file receipts, Stop, actor changes, and
unsettled leases still block continuation.
- No schema or migration change is required.

## Model Used

OpenAI GPT-6 in Codex. The exact deployment model ID and context-window
size are not exposed in this session. Used reasoning, code editing,
shell execution, and test tools.

DottaandClaude Opus 5.5 876a2e4857 fix(recovery): recover a prior boot's unstarted run at lease expiry (#19578)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - After a server restart, a task must continue automatically and
promptly when that is safe
> - A user clicks Retry, and the server is killed before the new run
starts a process
> - Recovery leaves that run `running` until the orphan reap's
five-minute stale-age threshold passes
> - The user sees nothing happen for about five minutes
> - This pull request recovers that run when its controller lease from
the earlier boot expires
> - The benefit is that the automatic retry starts about one lease
period after the kill, not five minutes later

## Linked Issues or Issue Description

**What happened?**
A Retry admitted a legacy run. The server was killed before the run
recorded a process. The run kept a controller lease from the killed boot
and `executionStage: preparing`. After the restart, live recovery
skipped the run until `updatedAt` was five minutes old
(`server/src/services/heartbeat/recovery.ts`, `staleThresholdMs ?? 5 *
60_000`). Restart-chaos measured 5 m 01 s from run creation to
`process_lost` and the automatic retry, twice (4 m 20 s after the server
was ready).

**Expected behavior**
Recovery should claim the run as soon as the earlier boot's lease
expires. The lease is the only liveness proof for a legacy controller,
and no process was ever recorded.

**Paperclip version or commit**
`master` at `71313207eb`.

**Steps to reproduce**
Click Retry on an interrupted task, then SIGKILL the server within about
one second. Observe the retried run stay `running` for about five
minutes.

## What Changed

- `recoverActiveExecutions` skips the stale-age gate for a legacy
`running` run when all of these are true: its controller lease is
expired (checked by the existing live-lease gate), the lease belongs to
an earlier boot (`controllerBootId !== legacyControllerBootId`), the run
is still `preparing` (no adapter dispatch), and the run has no recorded
`processPid` or `processGroupId`.
- The stage and process fields committed with the revocation are checked
again. If the old controller dispatched before its lease expired, the
run keeps the age guard.
- The existing revocation (`revokeExpiredLegacyControllerWithState`)
still requires the expired boot ID, so a concurrent renewal wins. The
existing `restartInterruptedBeforeDispatch` rule still decides the
single process-loss retry.
- `doc/execution-semantics.md` describes the rule in section 10.
- Two regressions in `server/src/__tests__/live-recovery-work.test.ts`
(embedded Postgres, real residual-recovery workers).

## Verification

- Red before the fix: `recovers a fresh run from a prior boot at lease
expiry ...` failed with `expected 'running' to be 'failed'`.
- Green after the fix: `pnpm exec vitest run
src/__tests__/live-recovery-work.test.ts -t "stale-age|fresh foreign
controller|suppressed live runs"` passes 4/4. The run fails
`process_lost` with `executionRecovery.providerWorkStarted: false`
within seconds of lease expiry, and exactly one retry runs to
`succeeded`.
- Race case: a DB trigger makes the row committed with the revocation
say `dispatching` while the scan saw `preparing`. The run stays
`running`, and no retry is created.
- Guard cases: a run with an expired lease of the current boot, a run
from an earlier boot with a recorded process, and a run from an earlier
boot that was `dispatching` (for example a remote HTTP adapter) all stay
`running` after four minutes.
- Related suites: `heartbeat-process-recovery`,
`heartbeat-observed-workspace-preservation`,
`native-startup-cleanup-recovery`,
`services/heartbeat/recovery.test.ts`, full `live-recovery-work`.
- Live K8 probe (restart-chaos supervisor, local instance, ACPX Claude
agent): the first run fails with a provider error, the probe clicks
Retry, and the server is SIGKILLed 100 ms later, before the Retry run
records a process. The probe then measures how long the Retry run stays
`running`.

| Build | Retry run created to `process_lost` | Server ready to
`process_lost` | Automatic retry run |
  | --- | --- | --- | --- |
  | Base (`71313207eb`) | 300.1 s | 293.5 s | started at 5 m 00 s |
  | This PR | 60.1 s | 54.5 s | started 0.1 s after `process_lost` |

The claim now happens when the killed boot's 60-second controller lease
expires. In this probe the restart took about 6 s, so the claim came
about 54 s after ready. In the restart-chaos waves, kill to ready took
about 41 s, so the claim would come about 20 s after ready.
- A chaos wave with the `retry` trigger (`w-20261106T195715-s2727`,
branch #19513 merged locally) missed the trigger: no Retry was offered
because recovery completed the task automatically (claude t01 PASS). The
probe above makes the Retry-then-kill timing deterministic.

## Risks

- Low risk. The change only removes an age wait. Ownership is still
proved by the expired lease of another boot. A rolling deploy or hot
restart whose earlier instance is still alive keeps renewing its lease,
so the run is not touched.
- Runs with a recorded process, and dispatched runs, keep the
five-minute guard. A process on another host or a remote request is not
inferred dead.
- Native runs are not changed. Their ownership is in
`native_run_finalizations` and startup native recovery.

DottaandClaude Opus 5.5 da9a4cb96c fix(native): retire a finished local Runner that stopped before suspending (#19597)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The native Runner path runs each per-turn agent turn through a
runnerd process, and the next turn must prove that the previous Runner
is finished before it takes over the saved session root
> - Under load, a local turn can have its result accepted while its
`runner.suspend` command does not finish, so the Runner's own receipt
stays unsuspended
> - The retirement proof that handles the same case for sandbox Runners
refused every local Runner with `target_not_sandbox_runner`
> - So the next turn failed with `runner_state_identity_mismatch:
prior_owner_terminal_state_indeterminate` and its session root was
quarantined
> - This pull request extends the retirement to a local Runner when the
prior Runner process is proven stopped by exact PID and start time
> - The benefit is that a follow-up turn (for example, after a user
answers a question) continues instead of failing

## Linked Issues or Issue Description

Refs #19525 (keeps the accepted result in the same incident; this is the
next run).

**What happened?**

In the runner E2E cell
`local-session-integrity.runner-acpx-claude.local.structured-question-restart-resume`,
the first turn asked a question and its result was accepted. The Runner
then logged `runner did not prove durable suspension before checkpoint`
(`runner.suspend` pending, Runner lifecycle `ready`). After a server
restart and the answer, the next run failed with
`runner_state_identity_mismatch:
prior_owner_terminal_state_indeterminate;
retirement_refused=target_not_sandbox_runner`, and its root was
quarantined.

**Expected behavior**

When the prior local Runner is provably stopped and every other
retirement proof holds, the next run retires that owner as a continuity
break and continues. If the stop cannot be proven, the run keeps the
named rejection.

**Steps to reproduce**

1. Run a local per-turn native turn whose `runner.suspend` does not
finish after its result is accepted (host load average ~40).
2. Start the next turn for the same session.
3. See `retirement_refused=target_not_sandbox_runner`.

## What Changed

- `server/src/services/native-runtime/native-restart-recovery.ts`: add
`proveNativeLocalRunnerStopped`. It uses the existing restart-recovery
checks: the recorded Runner PID is dead or now belongs to a process with
a different start time; its recorded process group is not alive; each
recorded provider process is dead or recycled. A missing PID, start time
or process group, a live recorded process, or a start time that cannot
be compared is not proof. When settlement already cleared the run's
process fields, the saved `native.local_process_stopped` receipt is the
Runner proof. Extract `nativeProviderProcessIdentities` (checkpoint plus
run events) so restart recovery and this proof read provider PIDs the
same way.
- `server/src/services/native-runtime/native-session-executor.ts`
(`retireFinishedPerTurnRunnerdOwner`, `readSettledRunnerdProjection`): a
local target is now eligible. For a local Runner, the projection accepts
the Runner's own unsuspended receipt for the same identity and
unfinished Runner lifecycle commands (`runner.suspend`, `runner.drain`,
`runner.shutdown`) only. All other proofs are unchanged: committed
result, released lease, no recovery state, stopped controller, delivered
terminal, other commands complete, tool inputs answered, quarantine
copies. The process proof runs before retirement and again just before
the archive.
- `doc/execution-semantics.md`: describe the local case.
- Tests: seven integration cases in
`native-recovered-owner-followup.test.ts` and ten unit cases in
`native-restart-recovery.test.ts`.

## Verification

- Red before the fix: the four new integration cases failed with
`retirement_refused=target_not_sandbox_runner`, which is the incident
error.
- Green after the fix: `pnpm exec vitest run
src/services/native-runtime/native-recovered-owner-followup.test.ts`
35/35. The new cases prove that a stopped Runner is retired (root
archived under `continuity-breaks`, no quarantine), and that a live
recorded Runner (`runner_process_alive`), a missing identity
(`runner_process_identity_missing`), and a pending non-lifecycle command
(`journal_commands_unsettled(turn.start.pending)`) keep the rejection.
All existing sandbox cases still pass, including "keeps an unsuspended
Runner receipt decisive" for sandbox targets.
- `native-restart-recovery.test.ts` unit cases: recycled PID, live
process, unknown start time, live group, live provider, missing PID or
start time.
- `native-session-executor.test.ts` + `native-restart-recovery.test.ts`:
1190 pass. `native-runner-restart-recovery.integration.test.ts` +
`native-restart-recovery-isolation.test.ts` (shared provider-PID
extraction): 81 pass. `tsc --noEmit -p server/tsconfig.json`: pass.
- Live: `pnpm test:e2e:runner -- --max-parallel 1
--max-automatic-retries 0 --id
local-session-integrity.runner-acpx-claude.local.structured-question-restart-resume`,
3 runs at eec57dd5ed: 3/3 PASS. The host load average was ~15 (the
incident had ~40), and `runner.suspend` finished in all three runs, so
these runs show no regression but did not exercise the new retirement
path. The integration cases cover that path.

## Risks

- The new path lets a follow-up archive a local root whose Runner
receipt is unsuspended. This is safe only if the Runner is stopped, so
the proof uses exact PID and start-time identity and fails closed on any
uncertainty. `ps` start times have one-second precision; a sub-second
difference is treated as the same process (not proof).
- A zombie-only process group on macOS can report as alive. That keeps
the rejection, as before.
- No quarantine behavior changes. A refused retirement still quarantines
the root as before.

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, through Claude Code
with tool use (shell, file edits, GitHub CLI). Extended reasoning on.
