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 c5c587f162 fix(issues): start a deferred children-completed wake the release drain missed (#20180)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A parent that delegates waits for its children, and is woken when
they finish (`issue_children_completed`)
> - Restart chaos t06 ended with both children done and the parent
blocked forever
> - The children finished while the parent's run was still going, so the
wake was deferred as a follow-up. That run then ended with the agent
setting the parent blocked, and the deferred wake was never started
> - The durable re-drivers for deferred wakes cover only
`issue_blockers_resolved`, so nothing else picks up a missed
`issue_children_completed`
> - This pull request makes both re-drivers cover children-completed
wakes too
> - The benefit is that a parent always hears that its children
finished, even when the release drain misses the deferred wake

## Linked Issues or Issue Description

Refs #19831 (durable ownership plan). Restart chaos wave
`w-20261109T041248-s9501`, task t06 (claude, M1, K2), Daytona per-turn,
master fa7950121d.

**Problem:** parent CHA-10 (all times UTC):
- 04:29:57: run 9cf49f52 started.
- 04:32:35 and 04:32:43: its children CHA-13 and CHA-14 finished.
- 04:32:43: `issue_children_completed` merged into the running turn.
- 04:32:53: that wake was deferred as a follow-up
(`issue_execution_deferred`, `deferred_issue_execution`, no run).
- 04:33:13: the turn ended with the agent setting the parent `blocked`,
a decision made before it saw the children's results.

The deferred wake stayed deferred for the rest of the wave, including
three later restarts. The parent sat blocked with no Retry. The
deferred-receipt worker (`deferred-receipt-work.ts`) and the
stranded-queue resume (`queue.ts`) select deferred dependency wakes with
`issueBlockersResolvedWakePayloadSql`, which matches only
`issue_blockers_resolved`.

## What Changed

- `server/src/services/issue-dependency-wakeups.ts`:
`dependencyResolvedWakePayloadSql` and `isDependencyResolvedWakePayload`
replace the blockers-only predicates. They match both
`issue_blockers_resolved` and `issue_children_completed` in
`_paperclipWakeContext.wakeReason`.
- The deferred-receipt worker and the stranded-queue resume use them, so
a deferred children-completed wake is started once the parent has no
live run, the same way a blockers-resolved one is.
- No code comments added.

## Verification

Red/green:
- `deferred-execution-receipt-work.test.ts` "starts a deferred
children-completed wake left behind when its parent's run blocked the
parent (restart chaos t06)". It sets up a blocked parent whose last run
succeeded, a done child, and the deferred `issue_children_completed`
receipt as t06 left it.
  - On master: the receipt stays `deferred_issue_execution` (red).
- With this PR: the receipt completes with exactly one
`issue_children_completed` run.
- `deferred-execution-receipt-work` and
`heartbeat-dependency-scheduling` pass (60 tests). `tsc --noEmit -p
server` is clean.

## Risks

- The workers now also select deferred children-completed wakes.
Admission is unchanged: they still pass the queue's own gates, and they
start only when the issue has no live run, the same as blockers-resolved
wakes.
- No schema change.

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 c49ab6b9ee feat(issues): wake the parent once when a child or blocker stalls on the board (#20098)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A parent task delegates to children and waits on blockers. Its agent
learns of progress only through wakes
> - Today only completion (`issue_children_completed`) and resolution
(`issue_blockers_resolved`) wake a waiting issue
> - In restart chaos `w-20261108T181313-s9701` t05, a blocker stopped on
a recovery action that needs the board, and its parent sat silently
blocked for 50+ minutes
> - This pull request wakes the waiting agent once per such stall, tells
it what it can do, and shows the stall on the parent's page with the
child's Retry
> - The benefit is that a stuck child or blocker no longer silently
strands its parent

## Linked Issues or Issue Description

Refs #19831 (durable ownership plan; restart chaos campaign). Restart
chaos wave `w-20261108T181313-s9701`, task t05 (M1, claude).

**Problem**

From the kept database:
- CHA-8 `blocks` CHA-5.
- CHA-8's board-owned recovery action (`native_session_retry_exhausted`)
was created at 18:44:02.909 and resolved with outcome `blocked` at
18:44:08, when CHA-8 moved to `blocked` for the board.
- CHA-5's only wake in the whole wave was its `issue_assigned` at
18:20:48. Its agent never heard about CHA-8.

**Expected behavior**
- When a child or blocker stalls on the board, the waiting agent is
woken once. It can then re-delegate, escalate, or block with a reason.
- The board sees the stall on the waiting task, with the child's Retry.

## What Changed

- **Shared:**
- `ISSUE_BLOCKER_STALLED_WAKE_REASON` (`issue_blocker_stalled`),
`ISSUE_BLOCKER_STALL_RELATIONS`, and the types
`IssueBlockerStallRelation` and `IssueBlockerStalledWakeContext`;
  - `Issue.stalledDependencies`.
- **Server, `services/recovery/blocker-stall-wakeups.ts`:**
- A stall is an issue that is not done or cancelled, whose latest
recovery action needs the board. That means either open
(`active`/`escalated`) and board-owned or escalated, or board-owned and
resolved as `blocked` while the issue is still `blocked`. The second
case is what t05 needed: recovery resolves its action that way when it
hands the issue to the board.
- Waiters are the parent, and every issue the stalled one `blocks`, when
they are open, visible and agent-assigned.
- Each waiter gets one wake per stall. The idempotency key
`issue_blocker_stalled:{waiter}:{stalled}:{recoveryActionId}` is checked
through the indexed `(company_id, payload->>'issueId')` path. A later
stall has a new action id, so it wakes again.
  - Each wake writes activity `issue.blocker_stalled_wake`.
- The pass runs from the recovery-action sweep
(`reconcileActiveRecoveryActions`) and from the per-issue blocked sweep
(`reconcileResolvedDependencyWakeBackstop`, which visits each blocked
issue). No new worker.
- A waiter's agent that cannot read the stalled issue (`issue:read`,
which honors private visibility) is woken without its title, identifier
or recovery details; the activity entry withholds them too.
- **Database:** migration `0450` adds the partial unique index
`agent_wakeup_requests_issue_blocker_stalled_uq` on `(company_id,
idempotency_key)` for `issue_blocker_stalled:` keys in delivered or
pending statuses, so two concurrent sweeps cannot both deliver a stall.
It is built `CONCURRENTLY IF NOT EXISTS` outside a transaction (listed
in `MIGRATIONS_WITH_TOP_LEVEL_STATEMENTS`).
- **Queue:** `allowsDependencyBlockedWake` (in
`run-dispatch/domain/wake-context.ts`) lets a stall wake run while the
waiter's blockers are unresolved, at both dependency gates. Without it
the wake was parked until the stalled blocker resolved, which is never.
Pause holds are unchanged.
- **Agent guidance:** the wake payload carries `blockerStall`, and
`renderPaperclipWakePrompt` adds a "Stalled dependency" section. It
names the task and its recovery action and the board's next action, then
the three choices: re-delegate, escalate with a comment, or block with a
reason naming the stalled task.
- **Other reason lists:** `issue_blocker_stalled` joins the
responsible-user wake reasons, the conversation execution-wake reasons
(it never drives a chat turn) and the wake diagnostic's known reasons.
- **Board surface:**
- `GET /issues/:id` returns `stalledDependencies`, readable issues only
(`readableIssueEdgeIds`).
- `StalledDependencyNotice` shows on the issue's chat notices, next to
`IssueBlockedNotice`: each stalled child or blocker, its board next
action, a link, and the child's own Retry (`useTaskRetry`), offered only
when the child's interruption allows it.

## Verification

Red/green:
- `server/src/__tests__/issue-blocker-stall-wakeups.test.ts` (14 tests).
  - On master: no `issue_blocker_stalled` wake is raised.
- With this PR: the parent is woken once per stall, and re-woken after a
new stall. A blocker's dependent is woken.
- The t05 shape (an action resolved as `blocked`) wakes once, and
nothing more after a Retry.
- No wake for an agent-owned action, a done, unassigned or hidden
waiter, or an action resolved another way.
  - `listStalledDependencies` lists children and blockers.
- `heartbeat-dependency-scheduling.test.ts` "admits an
issue_blocker_stalled wake while a blocker is unresolved". On master the
wake was parked (`null`); once admitted, the run-start gate cancelled
it. With this PR it runs with `dependencyBlockedInteraction`. The file:
14 passed.
- `packages/adapter-utils` `server-utils.test.ts`: the new prompt test
failed on master (no `blockerStall`). The file: 141 passed.
- `ui/src/components/StalledDependencyNotice.test.tsx`: 3 passed.
`IssueChatThread.test.tsx`: 109 passed.

Regression and static checks:
- Nearby server suites (recovery durable wait, dependency wake routes,
recovery actions, run-preparation): 149 passed.
- `tsc --noEmit` passes for `packages/shared`, `server` and `ui/src`.
- `pnpm check:token-gates` is clean.

Review round 1 (Greptile, Superagent), each with a regression:
- A backlog waiter is never woken. The waiter's status and assignee are
guarded at enqueue.
- One stall per run: no coalescing, so a merged run cannot keep only the
last stall's context.
- Only a delivered or pending wake ends a stall. A refused one
(wake-on-demand off) is retried after 10 minutes, and an agent that
takes no wakes is skipped without writing a row.
- Company-wide passes resume after the last stall a capped pass reached.
The per-issue sweep also checks the issue's own children and blockers,
which covers an unassigned stalled blocker.
- The dependency gates no longer trust the reason string.
`verifyBlockerStallWake` requires a system request, the stalled issue's
current stall action, and a real child or blocker edge. An
agent-requested wake with the same context is parked (tested).
- The notice shows a refused Retry's reason, and a lost response as
"Taking longer than usual…", with Retry still available (tested).

Review round 2 (Greptile), each with a regression:
- Race: two passes claiming one stall leave one delivered row (unique
index; the loser's insert is skipped).
- The company recovery sweep selects companies whose only stall is a
resolved-`blocked` board action, so an unassigned stalled blocker with a
todo waiter is reached.
- Private stalled issue: the waiter's wake and activity carry no title,
identifier or recovery details.
- `GET /issues/:id` always returns `stalledDependencies`, so a cleared
stall replaces the cached list.
- The notice shows a failed child read with a Reload button (tested).
- `pnpm --filter @paperclipai/db check:migrations` passes.

Review round 3 (Greptile), each with a regression:
- A stall wake that fails to enqueue is retried: the recovery-action
pass reports `blockerStallWakeFailures` and the dependency pass counts
it in `enqueueFailed`, so the worker throws and retries at its backoff
(`issue-recovery-work-lifecycle.test.ts`).
- The notice drops a stall once the child's refreshed status has moved
on (`StalledDependencyNotice.test.tsx`, 7 tests).

## Risks

- A deploy wakes the waiters of every issue that is stalled today, once
each. That is intended (they are stranded now), and it's bounded at 200
stalls per pass.
- A stall wake may run while blockers are unresolved, like a comment
wake. It is bounded to one per stall, and pause holds still apply.
- The agent skill (`skills/paperclip`, CODEOWNER-owned) does not yet
list the new reason. The wake prompt carries the guidance.
- One additive index, built concurrently; no persisted run state change.
Existing rows cannot violate it before deploy, since no
`issue_blocker_stalled:` keys exist yet.

DottaandClaude Opus 5.5 c4ba3974a7 fix(heartbeat): close run admission before a graceful shutdown closes its listener (t09) (#20102)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A graceful restart (K2) drains the control plane: it closes HTTP
admission, suspends running runs, and the next boot resumes them
> - Run admission stayed open while the HTTP listener closed.
Heartbeat's shutdown flag was set only later, inside hot-restart
preparation
> - A run that finished in that window released its issue and promoted
the queued comment wake. That started a new run that had no callback
listener
> - A remote warm continuation then failed with
`local_runtime_api_listener_unavailable`, and the task needed a Retry
(restart chaos t09)
> - This pull request closes run admission before the listener closes,
so the promoted wake stays queued for the next boot
> - The benefit is that a comment sent during a deploy continues on its
own after the restart

## Linked Issues or Issue Description

Refs #19596

**What happened?**
In restart-chaos wave w-20261108T192459-s9501 (Daytona warm, Codex C1,
K2), a K2 SIGTERM started a graceful drain at 19:42:52 UTC, and the HTTP
listener closed first. At 19:43:03 the running turn finished and
released its issue. That promoted the queued comment wake, and
`startNextQueuedRunForAgent` started a new run about 11 s into the
drain. Backend setup resolved the local runtime API URL, found the
listener closed, and threw `local_runtime_api_listener_unavailable`. The
remote target is excluded from the closed-listener handoff, so the run
failed, and the task waited for a manual Retry.

**Expected behavior**
No queued run starts once a graceful shutdown has begun. A wake promoted
during the drain stays queued, and the next boot starts it with no
Retry.

**Steps to reproduce**
1. Run a remote warm task and post a comment while its turn runs, so the
comment wake queues behind it.
2. Send SIGTERM to the control plane just before the turn finishes.
3. Before this change, a new run starts during the drain and fails with
`local_runtime_api_listener_unavailable`.

**Paperclip version or commit**
master at d007afbf86 (the wave ran on c5a172a183).

## What Changed

- `heartbeat/run-admission.ts` (new): a process-wide run admission gate
(`closeProcessRunAdmission`, `isProcessRunAdmissionClosed`). HTTP routes
build their own heartbeat instances, so the gate cannot live in one
instance.
- `heartbeat/queue.ts`: a new optional dependency,
`isRunAdmissionClosed`, which defaults to the process-wide gate.
`startNextQueuedRunForAgent`, `resumeQueuedRuns` and
`resumeQueuedRunsAfterDrain` start nothing (and read nothing) once it
returns true. Wakes are still recorded and promoted; only the start is
held.
- `heartbeat.ts`: also honors its own `shutdownInProgress` flag.
- `shutdown.ts`: `closeHttpListenerForShutdown` takes
`closeRunAdmission` and calls it first, before it checks or closes the
listener. `index.ts` passes `closeProcessRunAdmission`.

## Verification

- Red/green, new tests:
- `queue.test.ts`: "starts no run once shutdown closed run admission"
(for `startNextQueuedRunForAgent` and `resumeQueuedRuns`), and "honors
the process-wide run admission gate in every heartbeat instance".
- `shutdown.test.ts`: "closes run admission before it stops accepting
requests".
- `pnpm exec vitest run src/services/heartbeat/queue.test.ts
src/services/heartbeat/recovery.test.ts
src/__tests__/heartbeat-comment-wake-batching.test.ts
src/services/native-runtime/native-startup-retry.integration.test.ts
src/shutdown.test.ts` (server): 5 files, 277 tests passed.
- `PAPERCLIP_TYPECHECK_LOW_MEMORY=1 pnpm typecheck` (server): passed.

## Risks

- Low risk. Only queued-run starts are held during a shutdown that has
already begun; wakes, drains, suspension and finalizers are unchanged.
The next boot's queued-run dispatch starts held runs.
- Known remaining window: a run admitted just before shutdown can still
reach backend setup after the listener closed. A local runner hands off
to restart recovery there. A remote warm continuation still fails,
because the remote target is excluded from that handoff (#19596) and the
bootstrap retry does not cover warm continuations. This change removes
the t09 sequence, where the run started after shutdown had begun; it
does not remove that narrower window.

DottaandClaude Opus 5.5 cf9c81d9a7 perf(run-log): record named preparation phases before dispatch as run-log spans (#20046)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Every native run records performance spans in its run log, the
instance-local `heartbeat_run_events` table, so slow turns can be
diagnosed without any external service
> - The steps between environment acquisition and dispatch are timed by
named preparation phases, but those timings reach only OpenTelemetry,
which is off unless an operator configures an endpoint
> - On a Daytona follow-up in a paperclip-sized workspace, 17–30 s sat
in one opaque span, `heartbeat.prepare_after_environment`
> - This pull request also records the named preparation phases, and
their nested steps, as run-log spans
> - The benefit is that the next slow step shows up by name in the run
log; this change found a full workspace re-upload on every remote turn

## Linked Issues or Issue Description

**What happened?**
The run log showed `heartbeat.prepare_after_environment` at 17–30 s on
Daytona follow-ups, with nothing inside it. The phases that would
explain it (`heartbeat.prepare.*`, `runtime_selection.*`,
`workspace_sync.*`) were recorded only as OpenTelemetry spans, and those
are a no-op without an OTLP endpoint.

**Steps to reproduce**
1. Run a Codex task on a Daytona environment with a large repository as
the project workspace.
2. Post a follow-up comment.
3. The run log shows one large `heartbeat.prepare_after_environment`
span with no children.

**Expected behavior**
The run log names the steps that make up the wait.

## What Changed

- `execution-preparation-timing.ts`: every named preparation phase
(`measure`) and nested run phase (`measureRunPhase`) records its start,
end and outcome in a per-run in-memory list.
- Bounds: phases under 50 ms are skipped, at most 200 per run, at most
256 runs held.
- Without a tracer, the run scope is still set, so nested phases reach
the run.
  - OpenTelemetry behavior is unchanged.
- `runtime-execution.ts`: at native dispatch, the recorded phases are
drained into the run's preparation spans under `task.prepare`.
- `runtime-selection.ts`: the remote Codex CLI version read and the
runtime context build get their own phases,
`runtime_selection.codex_cli_version` and
`runtime_selection.runtime_context`.

## Verification

- `execution-preparation-phases.test.ts`: a slow phase is recorded and a
fast one skipped, a failure is marked, draining clears the run, runs are
kept apart, and a nested `measureRunPhase` step is recorded without a
tracer.
- `database-operation-attribution`, `company-skills-observability` and
`github-catalog-timing`: pass (15 tests in total).
- Daytona Codex run in a fresh paperclip clone: the follow-up's 17.8 s
gap now reads `heartbeat.prepare.runtime_selection` 15.7 s, then
`runtime_selection.workspace_sync` 15.4 s, then
`workspace_sync.transfer` 13.3 s.

## Risks

- This is a run-log change only, not Telemetry: the data stays in the
instance database. It adds roughly 10–40 spans per run, bounded as
above.
- The recorder is in memory and per process. A run that never dispatches
is evicted when the cap of 256 runs is reached.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, via Claude Code with
tool use (shell, file editing, test execution, Daytona measurements).

DottaandClaude Opus 5.5 c966334ec3 fix(recovery): settle a run-less lease once its stamped holder is proven gone (#20026)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The control plane recovers in-progress records after a server
restart through a shared ownership path
> - Run-less sandbox leases (login, probe, harness verification) were
released only by a five-minute idle sweep
> - That sweep releases by age: it leaves a dead holder's sandbox for
minutes and takes a live login session's sandbox
> - This pull request settles a run-less lease only when its stamped
holder is proven gone
> - The benefit is no stuck sandbox after a restart, and no live session
loses its sandbox

## Linked Issues or Issue Description

Related: #19965 (named the owner of login/probe leases), #19964 (the
run-lease settle this mirrors). No duplicate PR was found.

**What happened?**

The final Daytona chaos wave `w-20261108T083036-s9401` recorded I2
`environment_login_probe_lease` (`pid_dead`) on 2 records. These were
the codex agent's harness-verification leases. A restart killed their
holder. The leases stayed `active` until the five-minute idle sweep
released them. The same sweep releases any run-less lease after five
idle minutes, also when its holder is alive.

**Expected behavior**

A run-less lease is released as soon as its stamped holder is proven
gone. A lease whose holder is alive is never released, however long it
is idle.

**Steps to reproduce**

1. Start a Daytona wave: `node cli/node_modules/tsx/dist/cli.mjs
tests/restart-chaos/main.ts --env daytona --daytona-image <image>`
(K1/K4 faults).
2. Let a fault kill the server while an agent's harness verification
holds its sandbox lease.
3. See the reconciler report I2 `environment_login_probe_lease` until
the idle sweep releases it.

**Paperclip version or commit**

`master` at `8475826d2d`.

## What Changed

- New `settleEnvironmentLoginProbeLease`, registered on
`environment_login_probe_lease`. It runs only for a stamped holder that
is proven gone, and compares and swaps on that exact stamp.
- It moves the lease to `pending_cleanup` with the recovered-orphan
reason, so the cleanup sweep destroys the sandbox in its next tick.
- It leaves the lease alone when a legacy shutdown fence applies, or
when another live lease holds the same provider resource.
- The idle sweep for run-less leases now covers only legacy rows saved
before holders were stamped (no `leaseController` key). Stamped rows are
never released by age.
- `holderUnchanged` is now exported from the run-lease settle so both
settles share it.
- The controller stamp (`leaseController`, and every other
`ControllerProcess` stamp) now records the platform deployment when the
platform names one (Railway: project, environment, service, deployment,
volume). `controllerStamp` passes it to `proveOwnerGone`. A container
redeploy changes the PID space, and the old stamp would read
`different_process_space` (unprovable) forever. Now the existing
`deployment_replaced` proof shows the old holder gone. This also covers
`environment_run_lease_active` and the other kinds built on
`controllerStamp`.
- `currentDeploymentIdentity` in `owner-proof.ts` now delegates to
`currentControllerDeployment`, so there is one parser.
- Data doc: added the final Daytona wave, the six Daytona-only crash
points (4 pass, 2 not reached, no violations), and the cause of the
roughly 450 s codex TTFT. Runs waited behind the agent's harness
verification, which restarted after each fault; boot itself took about
32 s.
- Restart-chaos README: corrected which Daytona crash points a plain
task reaches.

## Verification

- Red, before the change:
`environment-login-probe-lease-ownership.test.ts` failed 3 of 6. No
settle happened, and the idle sweep released 3 live holders' leases.
- Green: `pnpm exec vitest run` passes for
`environment-login-probe-lease-ownership`,
`environment-run-lease-ownership` and
`heartbeat-orphaned-active-lease-sweep` (45/45), and for
`environment-lease-owner-stamps`,
`heartbeat-observed-workspace-preservation`,
`ownership-reconciliation-report`, `heartbeat/recovery` and
`workspace-recovery-warm-handoff`.
- Redeploy: a stamp from a replaced Railway deployment settles with
`deployment_replaced`. A stamp from the same deployment in another PID
space stays `active`. This was red when `controllerStamp` dropped the
deployment.
- Live-owner counter-cases: the current process, another live PID,
another PID space, and a lease re-stamped after the proof all stay
`active`. A read-only pass never settles.
- Not re-run live: the Daytona wave and crash points ran before this
fix. The next Daytona wave should show no
`environment_login_probe_lease` I2.

## Risks

- A stamped run-less lease whose live holder never releases it, because
of a bug in that process, is no longer released after five idle minutes.
It is released once that process exits. This is the intended trade:
never take a live holder's sandbox.
- On an ephemeral server without a platform deployment identity (not
Railway), a stamp from a replaced container is still unprovable. Such a
run-less lease stays `active` until the provider expires the sandbox,
and the reconciler reports it as unprovable. Before this PR, the
five-minute sweep released it by age. This is the same open gap as
unstamped legacy leases on an ephemeral server: there is no operator
action yet. It is listed as a Phase 2 follow-up.
- Legacy unstamped run-less leases keep the age fallback. These are rows
written before #19965, and no current code writes them.

DottaandClaude Opus 5.5 20cc6faca3 feat(recovery): settle legacy shutdown fences of proven-gone servers on the shared path (#20017)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When a server shuts down gracefully during a sandbox run, it commits
a fence on the run's lease so no cleanup worker destroys the sandbox
before its files are exported
> - The fence names its server only by boot id. It is released when its
owner settles, or when its 30 s deadline (renewed every 10 s) passes.
After a restart, the sweep still waits for that deadline even though the
old server is gone
> - The durable ownership plan proves owners by identity through one
shared prover and settles them from one reconciler
> - This pull request stamps the committing process on the fence and
settles it when the shared prover shows that process gone. The outcome
is the same safe one an expired deadline gives: the source is preserved
and the restore failure recorded
> - The benefit is that the fence releases on proof, not age, and a
fence whose owner may still be alive (another host, or an older marker)
keeps its deadline

## Linked Issues or Issue Description

Refs #19831 (plan, Phase 2 sections A and C), #19838 (inventory: "Legacy
graceful-shutdown workspace settlement fence", and "A boot-id mismatch
alone does not release").

**What happened?**
`legacy_shutdown_settlement_fence` was report-only, and its owner stamp
had only a boot id. A fence left by a crashed or replaced server could
be released only by its deadline.

**Expected behavior**
A fence whose committing process is proven gone (a dead or reused PID in
the same PID space) settles from the recovery sweep and from the shared
reconciler. An unprovable owner keeps the renewed deadline as its fenced
takeover.

## What Changed

- `legacy-shutdown-workspace-settlement.ts`:
- `beginLegacyShutdownWorkspaceSettlement` stamps `controller`
(`currentControllerProcessStamp`, no I/O).
  - New `legacyShutdownSettlementOwnerStamp`.
- `allowLegacyShutdownWorkspaceCleanup` takes `ownerProvenGone`, which
replaces only the deadline check, and only while the marker still names
that process. Every other guard is unchanged: owner stop, competing
allocations, in-flight cleanup.
- The sweep also proves the owners of fences from other boots that are
still before their deadline.
  - New `settleLegacyShutdownSettlementFence` for the reconciler.
- `recovery/ownership-registry.ts`: the kind uses the full stamp when
present and registers the settle.
- The settling-kinds list in `ownership-reconciliation-report.test.ts`
is updated.

## Verification

- `heartbeat/recovery.test.ts`: 100 pass. Three new tests fail on
`master` and pass here:
  - the fence stamps the committing process;
- a previous server proven gone settles before the deadline (restore
failure recorded);
- the reconciler settles only the proven-gone owner (a read-only pass
changes nothing). Another host and a boot-id-only marker stay pending
until their deadline, then expire as before.
- `ownership-reconciliation-report.test.ts` (25) and
`environment-retained-orphan-sandbox.test.ts` (19) pass.
- The server package typecheck passes.

## Risks

- A proven-gone owner now expires the fence up to 30 s earlier than
before. Expiry preserves the source (stop-and-retain or a
`retain_on_failure` hold) and never destroys provider files.
- Markers written before this change have no `controller` and behave
exactly as before.

execution in Claude Code.

DottaandClaude Opus 5.5 5978b7a1e0 fix(chat): tell chat agents when the Conference Room is enabled and what it is (#20036)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent Chat lets a person talk to an agent in a standing conversation
> - The Conference Room is a separate, experimental board chat surface
at `/<prefix>/board-chat`
> - A chat agent cannot read the experimental settings, so it cannot
know that the Conference Room exists
> - When a person asks to "discuss the launch in the conference room",
the agent treats the phrase as a metaphor and asks launch questions
> - This pull request tells the chat agent about the Conference Room
only while the experiment is on
> - The benefit is that the agent links the real surface and states its
actual scope

## Linked Issues or Issue Description

**What happened**
A person said "Let us discuss the launch in the conference room." in
Agent Chat on a local-trusted instance with Conference Room Chat
enabled. The agent's reasoning asked whether the conference room is a
Paperclip feature. It found no information, because the experimental
settings endpoint is board-only. It replied with launch questions and
gave no link to the Conference Room.

**Expected behavior**
The agent links the Conference Room (`/<prefix>/board-chat`) and says
what it is: a separate board assistant whose history does not carry over
from the chat. When the experiment is off, the agent does not mention
it.

**Steps to reproduce**
1. Enable Conference Room Chat in Instance Settings > Experimental on a
local-trusted instance.
2. Open a chat with the CEO agent.
3. Send "Let us discuss the launch in the conference room."
4. See that the reply gives no Conference Room link.

## What Changed

- Add `CONFERENCE_ROOM_CHAT_DIRECTIVE` in
`server/src/services/agent-conversations.ts`. It gives the route as a
Markdown link and states the real scope of the surface.
- Render the directive in standing-chat task markdown only when
`conferenceRoomEnabled` is true
(`server/src/services/heartbeat/task-markdown.ts`).
- Set `conferenceRoomEnabled` from the experimental settings that the
heartbeat already loads
(`server/src/services/heartbeat/task-context.ts`). No new query runs
before the turn starts.
- Add a regression test for the enabled, disabled, and non-chat cases.

## Verification

- `cd server && pnpm exec vitest run
src/services/heartbeat/task-markdown.test.ts` passes (16 tests).
- `npx tsc --noEmit -p server/tsconfig.json` passes.
- End to end: the `agent-chat.conference-room` chat eval runs with this
commit cherry-picked onto its case branch.

## Risks

- Low risk. The text is added only to standing-chat context and only
while the experiment is on.
- The directive does not check the deployment mode. It says that the
surface works only on a local single-operator instance, and the route
itself refuses other deployments with a clear error.

## Model Used

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

DottaandClaude Opus 5.5 7c56147bb3 fix(workspaces): a busy-workspace holder whose controller lease is held is live, however silent (#20023)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Two runs must never write one workspace at once. A run that finds a
workspace held (a remote workspace's writer run, or a running holder of
a shared local tree) waits behind it
> - The holder counted as live only while it produced output: after 60
minutes of silence it was "stale"
> - For the shared local tree, that meant the waiter went ahead while
the silent holder might still be working, which is a second writer.
>   - For a remote workspace, the waiter failed instead of waiting.
> - Silence is not proof a run stopped. A long tool call can be silent
and alive
> - The durable ownership plan proves ownership by identity or by a held
fence, never by age
> - This pull request treats a holder whose controller still renews its
lease (the legacy controller lease or the native coordinator lease) as
live, however silent. The 60-minute rule applies only once that fence
lapses
> - The benefit is that a silent but live holder is never overtaken. A
dead holder is still settled by the run reapers, which wake the waiters

## Linked Issues or Issue Description

Refs #19831 (plan, Phase 2 sections A and C, and Phase 3 E), #19838
(inventory: "Remote workspace writer lane", and the "Released only by
TTL/age" list: "Remote writer lane: 60 min").

**What happened?**
`WORKSPACE_BUSY_HOLDER_STALE_AFTER_MS` (60 min of output silence)
decided whether a running holder still held a workspace. This applied in
four places:
- the remote reservation deferral;
- the parked busy-workspace wait;
- `findSharedWorkspaceHolder`, which stopped counting the holder at all;
- `findExecutionWorkspaceHolder`, which flagged it stale.

**Expected behavior**
A running holder whose controller lease is held is live by fence. Only a
holder with no held fence is judged by the silence cutoff, which keeps
the visible failure instead of parking forever. The check is
database-only (`runOwnerFenceHeldSql`): no process probe on the
workspace-preparation path before a turn starts.

## What Changed

- `remote-workspace-writer-hold.ts`: new `runOwnerFenceHeldSql`. It is
true while `heartbeat_runs.controller_lease_expires_at > now()` or the
run's native coordinator lease is held.
`RemoteWorkspaceWriter.ownerFenceHeld` is reported for a running writer.
- `heartbeat/workspace-preparation.ts`: the reservation keeps deferring
behind a silent writer whose fence is held.
- `run-dispatch/adapters/workspace-busy-wait.ts`: a parked wait behind a
running holder with a held fence stays parked and re-checks at the
parked cadence.
- `heartbeat/retries.ts`: `findSharedWorkspaceHolder` counts a silent
holder whose fence is held. `findExecutionWorkspaceHolder` flags a
holder stale only when it is silent and its fence lapsed.

## Verification

- `heartbeat/workspace-preparation.test.ts`: 138 pass. The extended
"waits for the live writer of an inherited remote … at reservation"
(both modes) fails on `master` and passes here: a silent writer with a
held lease defers, and once the lease lapses it is the 409 as before.
- `heartbeat-workspace-busy.test.ts`: 41 pass. The new "still defers
behind a silent holder whose controller renews its lease" fails on
`master` and passes here. The existing "does not defer when the only
holder has been silent past the staleness threshold" (no lease) still
passes.
- The server package typecheck passes.

## Risks

- A silent holder whose controller is alive now blocks waiters for as
long as it holds its lease. That is the safe direction. A hung but live
run is the active-run silence watchdog's to handle, and a dead
controller's lease lapses within a minute.
- The extra predicate is an indexed lookup of the run's own row and its
coordinator row.

DottaandClaude Opus 5.5 7c508d3e42 fix(recovery): collapse the two lost-process reapers onto one stamp and the shared owner prover (#20004)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When the control plane restarts, it must decide whether each running
agent's process is gone before it releases the run
> - Two reapers made that decision for legacy runs, with different rules
and different outcomes. One also waited 5 minutes even when it could
already prove the process was dead (RC-27)
> - The durable ownership plan moves every such decision onto one
prover, `proveOwnerGone`, and never releases work by age alone
> - This pull request collapses the two reapers onto one owner stamp and
the shared prover, removes the age wait for a proven-dead process, and
never releases a process it cannot prove gone
> - The benefit is that a lost process ends one way, at once, with its
normal retry, and a process on another host is never released by mistake

## Linked Issues or Issue Description

Refs #19831 (plan, Phase 2 sections A and C), #19838 (inventory: "One
fact, many proofs" and the age-only list), #19871, #19883, #19953,
#19997.

**What happened?**
- `recoverActiveExecutions` (heartbeat) and
`terminalizeOrphanedRunningRun` (recovery service) both judged a lost
legacy child. They used different liveness rules (EPERM counted as alive
in one, dead in the other) and gave different outcomes:
`failed/process_lost` with a retry in one,
`interrupted/orphaned_running_run` with no retry in the other.
- The active-execution reaper kept a 5-minute age guard even when the
child was provably dead.
- Hot-restart adoption judged the child with raw PID checks.

**Expected behavior**
One prover decides. A child that is proven gone is settled at once,
through one path with one outcome. An unprovable child (another PID
space, a sandbox, or a pre-#19871 row on an ephemeral server) is never
released, and Stop is its operator action.

## What Changed

- New `server/src/services/run-process-owner.ts`:
`lostProcessOwnerStamp` and `proveRunProcessGone`. They wrap the shared
`runProcessOwnerStamp` (#19997) with the one-release legacy fallback
(#19883) and the group-leader case.
- `heartbeat/recovery.ts`:
- The active-execution reaper judges a legacy child with the shared
prover. A child proven gone skips the age guard; master's exemption for
a proven-gone controller (#19953) is kept.
- An unprovable child gets the detached marker, whose message says to
stop the run.
- The legacy host fallback is recorded as `LEGACY_HOST_FALLBACK_EVENT`.
- `heartbeat/recovery.ts` (hot-restart adoption): a run is marked lost
only on a `gone` proof. An unprovable child stays adopted and held.
- `recovery/service.ts`: the stale-lock sweep no longer judges a legacy
child. It hands the run to `settleLostRunProcess`, which is the
active-execution reaper wired in `heartbeat.ts`, and then reads the
outcome back. Native runs keep the sweep's own backstop, now judged with
the shared prover.

Salvaged from the stopped Phase 2 recovery agent's uncommitted work,
which had no tests. I completed and corrected it: the salvaged adoption
marked unprovable children lost, which risked duplicate execution.

## Verification

- `recovery-stale-issue-lock-sweep.test.ts` (51 pass). Three new tests
fail on `master` and pass here:
- "hands a legacy run whose child is proven gone to the one lost-process
reaper";
- "settles a legacy run whose child is proven gone without waiting out
the age guard";
- "never releases a legacy run whose child is unprovable, and names Stop
as the way out".

  Updated tests:
  - The PID-space test now expects `failed` for the one legacy outcome.
  - The explicit-retry race now injects `settleLostRunProcess`.
- The two tests of the sweep's own terminal write use native runs, which
keep that path.
- `heartbeat-process-recovery.test.ts`: 418 of 419 pass. The one
failure, "redacts opaque environment-bound credentials from Sentry
diagnostics", also fails on unchanged `master`.
- `heartbeat/recovery.test.ts` (97),
`ownership-reconciliation-report.test.ts` (24),
`native-remote-retry-admission.test.ts` (92) and
`heartbeat-provider-limit-wait.test.ts` (4) pass.
- The server package typecheck passes.

## Risks

- Behavior change: a legacy run whose child died, when the orphan sweep
finds it, now ends `failed/process_lost` with the reaper's retry policy,
instead of `interrupted/orphaned_running_run`.
- A pre-#19871 row on an ephemeral server, or a child in another PID
space, now stays `running` with a detached marker until Stop. It is no
longer released by age.
- Not changed: a dispatched legacy run that recorded no PID and has no
controller stamp keeps its lease-expiry plus age fence. Rows written
since #19953 are judged by the controller proof. Older rows, and remote
handoff, keep the fence. A different host is never proof, so removing
the fence would strand runs after an ephemeral replacement.

DottaandClaude Opus 5.5 8475826d2d fix(wake-queue): deliver user comments whose wake a restart lost or a stale continuation dropped (#19992)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A user's follow-up comment on a task must reach the agent exactly
once, through restarts (invariant 4)
> - The final unmasked local chaos storm (96 tasks, 31 restarts) passed
94 tasks. The 2 failures were both lost user comments
> - In t69, a restart killed the server between saving the comment and
writing its wake. In t72, a comment's own run was cancelled as stale,
because the earlier run completed the task first without reading the
comment
> - This pull request adds a reconciler rule that gives a lost comment
its wake, and saves the comment before a stale cancellation
> - The benefit is that a user's message is never silently dropped when
a restart or a completion race hits at the wrong moment

## Linked Issues or Issue Description

Refs #19956 (work-intent outbox), #19944, #19831 (plan, invariant 4).

**What happened?**
In chaos wave `w-20261108T055444-s9401` (local, unmasked, codex and
claude, 30-min K13 storm, master `46bf913fb9`), 94 of 96 tasks passed.
Two failed:
- **t69, R1 `rested_not_done`.** The user's comment was saved at
06:14:59.358 and reopened the task to `todo`. A K1 SIGKILL fired 28 ms
later, before the wake was written. No wake row exists. Recovery skips a
`todo` task whose last run succeeded, so the task sat with no run until
the wave ended.
- **t72, R4 `concurrent_runs`.** A comment posted during a run queued
its own run. That run was claimed at 06:16:04.874. The first run's
completion marked the task `done` 2 ms later. The comment's run was then
cancelled with `continuation_task_ownership_changed` before dispatch,
and the comment was lost.

**Expected behavior**
Each accepted user comment is delivered once, unless the task is
cancelled or reassigned, or a person closes it.

**Steps to reproduce**
`node cli/node_modules/tsx/dist/cli.mjs tests/restart-chaos/main.ts
--replay w-20261108T055444-s9401/t69` (or `.../t72`).

## What Changed

- `recovery/ownership-invariant-report.ts`: a new reconciler-owned I4
rule, `user_comment_without_wake`. It finds a user comment that meets
all of these conditions:
  - it is newer than every run of the task;
- the task is assigned, is not a conversation, has no live run or lock,
and has at least one earlier run;
  - no wake request carries the comment.

A comment younger than 30 s is not reported yet, because it may still
get its normal wake. Its end-of-grace time is returned as `nextDueAt`.
- `native-runtime/native-finalization-reconciler.ts`: the backstop step
is now exported as `applyOwnershipReportBackstops`. For each such
comment it saves the missing outbox receipt (`executionWait: wake_lost`)
and promotes it.
- `work-intent-outbox.ts`: new `saveUndeliveredUserComments`, which the
reconciler rule and the stale-run path both use. It saves only live user
comments that no completed run received. It writes nothing for a task
that is reassigned, is a conversation, or has a status the caller does
not allow.
- `heartbeat/queue.ts`: the saved-receipt pass that already sends
pause-saved messages also sends `wake_lost` receipts. It uses the same
per-comment consumption check and the same chat-input exclusion.
- `heartbeat/stale-comment-continuation.ts` and `heartbeat.ts`: before a
stale continuation is cancelled, its undelivered user comments are saved
as a deferred receipt. The release drain then reopens the `done` task
and delivers them once. This applies only when an agent run that started
before the comment completed the task after it. A task that a person
marks done is left closed.
- `tests/restart-chaos/grader.ts`: R4 ignores runs cancelled before
dispatch (`continuation_task_ownership_changed`) when it looks for
overlapping execution. Those runs never executed. Comment consumption
still counts them.

## Verification

Each focused file ran alone in one process (`--maxWorkers=1`):
- `heartbeat-held-comment-wake.test.ts` (22 pass). This includes two new
cases:
- t69 shape: the reconciler rule fires, the backstop delivers the
comment once, and a second pass does nothing;
- t72 shape: the stale run is cancelled, the task reopens, and the
comment is delivered once.

  Both fail with the rule or the save disabled, and pass with them.
- `ownership-reconciliation-report.test.ts` (23 pass). It includes the
rule's boundaries: a carried comment, a too-young comment (deadline
only) and an already-read comment.
- `tests/restart-chaos/grader.test.ts` (17 pass). The new R4 case fails
with the old grader. A cancelled run that is not a pre-dispatch
cancellation still fails R4.
- Unchanged and passing: comment wake batching (27), refused assignment
wake (3), wake-queue postgres adapter (103), stale queue invalidation
(68), deferred receipt work (45). The first version also reopened a task
that a person had marked done, which broke one deferred-receipt test.
That case is now excluded.
- The server package typecheck and the restart-chaos harness typecheck
pass.
- Same-session chaos context on master: K6 crash loop
`w-20261108T063326-s9402`: 6 of 6 pass. The K4 long-hold wave is still
running. After merge, I'll replay only the targeted fault shapes (t69
and t72).

## Risks

- The reconciler rule runs on each report pass. It is bounded by the
1-hour lookback and the per-kind row cap, and it excludes conversation
tasks, so chat input keeps its own authorization.
- A comment younger than 30 s waits up to the end of its grace period
before the backstop acts.
- The stale-run save reopens a `done` task only for a comment that the
completing run could not have read.

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

DottaandClaude Opus 5.5 bf0d45a4d2 feat(recovery): settle teardown claims of dead claimants on the shared ownership path (#19966)
<!-- Write all pull request text in Simplified Technical English
(ASD-STE100): short sentences, one instruction per sentence, simple
approved vocabulary, and the active voice. -->

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A sandbox teardown writes a claim on its environment lease that
fences other cleanup for 15 minutes
> - After a restart, the cleanup sweep ended the fence of a claim whose
claimant had exited, with its own process check
(`releaseLostPendingCleanupClaims`)
> - Phase 2 of the durable ownership plan moves each in-progress record
kind onto one shared owner proof and deletes its bespoke check
> - This pull request registers a settle for
`environment_teardown_claim` and calls the shared path where the sweep
called the bespoke release
> - The benefit is one proof for every kind: a local claimant proves
death by its stamp; another host stays a fence handoff

## Linked Issues or Issue Description

Refs #19965
Refs #19964
Refs #19933

**What happened?**
The teardown claim had its own liveness check
(`controllerProcessExited`) in the pending-cleanup sweep. Each kind with
its own check can drift from the shared rules (PID space, PID reuse,
current boot).

**Expected behavior**
The shared prover judges the claimant stamped for this exact attempt. On
gone, the fence ends now and a counted sweep attempt is refunded once. A
claim held as a fence (another claimant or another host) waits for its
deadline.

**Steps to reproduce**
1. Start a sandbox teardown so the lease holds an in-flight claim.
2. Kill the server.
3. Restart. The claim must be released by the shared ownership path, not
by a separate check.

## What Changed

- `environment-teardown-claim-settlement.ts` (new): compare-and-swap
settle on the exact attempt and claimant. It ends the fence, refunds a
counted attempt, and is single-use. It never acts on a fence owner.
- `recovery/ownership-registry.ts`: `environment_teardown_claim`
registers the settle.
- `heartbeat/recovery.ts`: the sweep calls `settleOwnableKind(db,
"environment_teardown_claim")`. Deleted
`releaseLostPendingCleanupClaims` and its use of
`controllerProcessExited`.
- `environment-cleanup-state.ts`: the attempt cap, attempt key and their
SQL readers move here, so the settle and the sweep share one reader.
- `heartbeat-pending-cleanup-sweep.test.ts`: the overlap barrier now
holds the shared prover instead of the deleted check.

## Verification

- `cd server && npx vitest run
src/__tests__/heartbeat-pending-cleanup-sweep.test.ts
src/__tests__/environment-lease-owner-stamps.test.ts
src/__tests__/ownership-reconciliation-report.test.ts` (embedded
Postgres).
- The existing lost-claim matrix stays green on the shared path: retry
now; no failed-attempt charge for a dead server; one refund when sweeps
overlap; keep a live claim; keep a newer claim that kept an older
record; keep another host's claim; keep a claim without identity; page
past fenced claims.
- New, red before and green here (written after the code): the
reconciler pass ends a dead claimant's fence and refunds its counted
attempt.
- New counter-cases (green): a read-only pass never settles; a live
claimant, another PID space, and an unstamped fence claim keep their
fence.
- Full typecheck is left to CI (local memory limit).

## Risks

- Low risk. The settle keeps the previous release semantics (fence ends,
lease stays `pending_cleanup` and in flight until the sweep claims it
again).
- The stop-only claim still does not renew its fence; a live stop that
runs longer than 15 minutes can still be taken over. This change does
not alter that.
- Stacked on #19965 and #19964. Merge those first.

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 576ba29fff feat(recovery): settle the legacy controller lease on the shared ownership path (#19953)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Legacy (non-native) runs hold a controller lease on `heartbeat_runs`
while the server prepares and dispatches the adapter. The shared
ownership reconciler now settles proven-gone owners (Phase 2 of the
durable ownership plan)
> - The lease stamped only a boot id. The reconciler could never prove
its owner gone (`missing_identity` in the Phase 2 data), and recovery
released it by age: lease expiry (60 s), then a 5-minute age guard on
dispatched runs
> - A hard-killed server's legacy run therefore stayed `running` for up
to 6 minutes after the next boot
> - This pull request records the controller process with the claim,
registers a compare-and-swap settle, and makes live-run recovery use the
shared prover instead of the age guard when the controller is proven
gone
> - The benefit is that a dead controller's run is settled at once,
while a live, unprovable, or previous-release controller keeps today's
behavior

## Linked Issues or Issue Description

Refs #19933 (the settle hook, merged). Stacked on #19950 (migration
0446, registry) and targets its branch until it merges; then it
retargets to master.

**What happened?**
After a hard kill, a dispatched legacy run stayed `running` until its
controller lease expired and its last update was 5 minutes old.

**What did you expect?**
The next boot proves the old controller gone and fails the run as a lost
process at once.

**Steps to reproduce**
1. Start a legacy (non-native) run and let it dispatch the adapter.
2. Kill the server (SIGKILL).
3. Start the server. The run stays `running` for up to 6 minutes.

## What Changed

- `heartbeat_runs.controller_process` (jsonb, migration 0447): `{bootId,
pid, hostHash, processStartedAt}` of the claiming server process. It
names the controller only while its `bootId` equals
`controller_boot_id`. Revocation swaps the boot id, so a revoked lease
never keeps it.
- `legacyControllerClaim` writes it in the same UPDATE (from
`currentControllerProcessStamp()`, no I/O).
- `legacy-controller-lease.ts`: `legacyControllerOwnerStamp`,
`legacyControllerProvenGone` (calls `proveOwnerGone`), and
`settleLegacyControllerLease` (compare-and-swap expiry of the proven
controller's outstanding lease after it wakes live-run recovery).
- `ownership-registry.ts`: `legacy_controller_lease` registers `settle`
and `listForRuns`. The owner is the bound process; other rows are
boot-id fences. The listing covers outstanding leases only.
- `heartbeat/recovery.ts` (3 small hunks): a controller of another boot
that the shared prover proves gone has its live lease settled through
`settleOwnableKind` and skips the age guard. The local child-process
check after it is unchanged, so a live child still keeps the run
running.
- Migration 0447 builds the partial index with `CREATE INDEX
CONCURRENTLY` (heartbeat_runs is a known-large table) and is added to
`MIGRATIONS_WITH_TOP_LEVEL_STATEMENTS`.

Bespoke code deleted: none. The kind had no liveness proof; the age
guard stays for controllers that are not proven gone.

## Verification

- `cd server && npx vitest run
src/services/legacy-controller-lease.test.ts`: 33 passed.
- `cd server && npx vitest run
src/__tests__/ownership-reconciliation-report.test.ts`: 17 passed.
- Red with `recovery.ts` and `ownership-registry.ts` from the base
commit (tests, schema and lease module from this branch): 4 failed, 29
passed. Red: the crash-point reaper test, the expired-lease age-guard
test, the reconciler settle test, the exact-controller CAS test. The
tests were written after the code.
- New tests:
  - the claim stamps this process, and a changed boot id unbinds it;
- crash point: a controller dispatched the adapter and was killed with
its lease live; the startup reaper (default 5-minute age guard) fails
the run as `process_lost` at once;
  - a dead controller's expired lease skips the age guard;
- counter-cases keep the run and lease through the reaper and a
reconciler pass: a live earlier-boot PID, a dead PID in another PID
space, and a previous-release row with no `controller_process`; an
expired lease of a live controller stays behind the age guard;
- a read-only pass (`record: false`) never settles; a recording pass
expires the lease and leaves the run to live-run recovery;
  - settle refuses a controller that changed after the proof.
- Not run locally: typecheck (CI runs it) and the wide suites.

## Risks

- Previous-release story (rules/upgrade-safe-run-state.mdc): rows saved
by the previous release have no `controller_process`. They stay boot-id
fences with today's release (expiry, revocation, age guard). A rollback
ignores the column.
- Unprovable controllers (another host or PID space, unknown space, a
live PID with an unreadable start time) never release early. Their
handoff stays the lease expiry plus revocation, and the age guard. A
different host is never proof.
- Behavior change: a dispatched run whose controller is proven gone is
failed as `process_lost` without the 5-minute wait. The retry decision
is unchanged.
- The settle expires the lease only. Live-run recovery still settles the
run under its own checks. Accounting and workspace obligations are not
touched.
- The index build is concurrent. A cancelled build is retried by the
migrator's invalid-index handling.

DottaandClaude Opus 5.5 cc072e7c4e feat(recovery): settle orphaned active environment leases on the shared ownership path (#19964)
<!-- Write all pull request text in Simplified Technical English
(ASD-STE100): short sentences, one instruction per sentence, simple
approved vocabulary, and the active voice. -->

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agent runs hold environment leases (local workspaces and remote
sandboxes) while they execute
> - A crash between the terminal run write and the lease release leaves
the lease `active` with no holder
> - A sweep released such a lease when the run was terminal and the
lease was idle for five minutes. The age was the only guard against a
race with the live executor, which releases the lease itself with the
run's resource disposition
> - Phase 2 of the durable ownership plan moves each in-progress record
kind onto one shared owner proof (#19933 added the settle hook)
> - This pull request moves `environment_run_lease_active` onto that
path: the lease names its holder, the shared prover judges the holder,
and the settle never destroys a sandbox
> - The benefit is that a dead holder's lease settles on the next pass,
a live holder is never raced, and the five-minute age gate is gone

## Linked Issues or Issue Description

Refs #19933

**What happened?**
An orphaned active environment lease was released by age: "run terminal
plus five minutes" (the reaper in `heartbeat/recovery.ts` and the
live-recovery `orphanLease` worker). The ownership data showed one such
lease settle 119 s after it was ready. Without the age gate the sweep
could flip a lease to `pending_cleanup` (destroy) while the executor or
a recovery path was about to retain it.

**Expected behavior**
A run lease settles when its holder is proven gone, by identity and not
by age. A live holder is never raced. A settle never destroys a sandbox
whose files may still be needed.

**Steps to reproduce**
1. Start a run that holds an environment lease.
2. Kill the server after the run status becomes terminal and before the
lease release.
3. Restart. The lease stays `active` until the five-minute age passes,
then the sweep destroys the sandbox.

## What Changed

- `environments.ts`: the write that makes a lease active (insert and
same-run reacquire) stamps the holder process in
`metadata.leaseController`. The stamp does no I/O
(`environment-lease-controller.ts`).
- `recovery/ownership-registry.ts`: `environment_run_lease_active` lists
leases with their run status. The owner is the run while it is active,
then the stamped holder. It registers `settle` and `listForRuns`.
- `environment-run-lease-settlement.ts` (new): compare-and-swap settle
on the exact row (same run, status `active`, same metadata, terminal
run). A sandbox lease gets the stop-and-retain intent (stop and keep,
never destroy). Other leases move to `pending_cleanup` as before. It
keeps a lease that a pending native export, a legacy shutdown fence, a
shared provider resource, or an accepted native result still needs.
- `recovery/ownership-invariant-report.ts`: `settleOwnableKind` accepts
`currentProcessIdle`. A caller that passes every run this process
executes in `skipRunIds` may treat a current-process owner of another
run as gone (`current_process_idle`). The periodic pass never does this.
- `heartbeat/recovery.ts`: `sweepOrphanedActiveLeases` no longer
releases run leases by age. It runs native workspace preservation first
(a separate obligation), then calls `settleOwnableKind` with this
process's executions. Login and probe leases (no run) keep the idle
sweep until their own change.
- `heartbeat/live-recovery-work.ts`: a run lease is due now; only
run-less leases keep the five-minute idle deadline.
- `sandbox-stop-and-retain.ts`: an ownership settle records a recovery
marker on the intent and keeps `updatedAt`, so the pending-cleanup sweep
stops the sandbox in the same tick.
- Deleted: the age gate for run leases and the page-order bump for run
leases.

## Verification

- `cd server && npx vitest run
src/__tests__/environment-run-lease-ownership.test.ts
src/__tests__/heartbeat-orphaned-active-lease-sweep.test.ts
src/__tests__/ownership-reconciliation-report.test.ts` (embedded
Postgres).
- Red on unchanged master sources, green on this branch (tests were
written after the code):
  - stamps the lease holder in the write that makes a lease active
- settles a lease whose holder died after the run went terminal, on the
next pass (crash-point state: terminal run, dead holder in this PID
space)
  - stops and keeps a dead holder's sandbox instead of destroying it
- leaves a current-process lease to this process: settled only when it
is not executing the run
  - keeps the run fact alone for one release on a single-host server
- names no owner on an ephemeral server
(`PAPERCLIP_EPHEMERAL_SERVER=true`)
- the three updated sweep tests (sandbox stopped and kept, not
destroyed)
- Live-owner counter-cases (green): run still active; another live PID;
another PID space; current process while executing; read-only pass
(`record: false`) never settles; a lease re-stamped after the proof is
not settled; a legacy lease whose run this boot owns is kept.
- Also run green: `recovery.test.ts`,
`heartbeat-observed-workspace-preservation.test.ts`,
`workspace-recovery-warm-handoff.test.ts`,
`environment-service.test.ts`,
`heartbeat-pending-cleanup-sweep.test.ts`,
`native-environment-settlement-work.test.ts`,
`environment-cleanup-work.test.ts`.
- Full typecheck is left to CI (local memory limit).

## Risks

- Behavior change: an orphaned sandbox lease is now stopped and kept,
not destroyed. Workspace preservation and provider auto-delete decide
when it goes away. This can keep stopped sandboxes longer than before.
- A recovery path on another process can mark a run terminal while the
dead executor's stamp is still on the lease. The settle can then win
before that path releases. Because the settle only stops and keeps the
sandbox, files are not lost; the later release continues from the
stop-only intent.
- Previous-release rows: a single-host server keeps the run fact for one
release (a run this boot owns is excluded). An ephemeral server never
releases an unstamped lease; it stays visible as an I1 gap with no
operator action yet.
- No migration. The stamp lives in existing lease metadata.

DottaandClaude Opus 5.5 bf3a067076 feat(recovery): settle the finalizer and cleanup leases on the shared ownership path (#19950)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs keep their ownership in `native_run_finalizations`, and
the shared ownership reconciler now settles proven-gone owners (Phase 2
of the durable ownership plan)

retained-session cleanup lease (`native-cleanup:*`, 60 s) recorded only
a random token. They named no holder process
> - A server killed while it finalized or cleaned up kept the run
waiting for the whole lease. The lease was released by age alone. A
graceful shutdown also keeps an in-progress finalizer lease for the next
boot to wait out
> - This pull request records the holder process with each claim and
moves both kinds onto the shared prover and a compare-and-swap settle
> - The benefit is that a dead holder's run continues in the first pass
after boot, and a live or unprovable holder is never released

## Linked Issues or Issue Description

Refs #19933 (the settle hook and the first moved kind, merged).

**What happened?**
A finalizer or cleanup lease whose server process died stayed held until
the lease expired (5 min or 60 s). The run stayed `running` and its
follow-up work waited.

**What did you expect?**
The next boot proves the dead holder gone and frees the lease at once. A
live holder, or one that cannot be proven gone, keeps its lease.

**Steps to reproduce**
1. Accept a native result and let the finalizer claim it.
2. Kill the server (SIGKILL) before the finalizer commits.
3. Start the server. The run stays `running` for up to 5 minutes.

## What Changed

- `native_run_finalizations.lease_holder` (jsonb, migration 0446):
`{token, bootId, pid, hostHash, processStartedAt}` of the process that
took a token-only lease. It names the holder only while `token` equals
`lease_owner`, so renewals keep it and a later lease never inherits it.
The executor's `controller_*` columns are not changed.
- The finalizer claim (`native-run-finalizer.ts`) and the cleanup claim
(`native-session-executor.ts`) write it in the same UPDATE as the lease,
from `currentControllerProcessStamp()` (no I/O).
- New `native-token-lease-settlement.ts`: compare-and-swap settle that
expires exactly the proven-gone holder's outstanding lease, after it
notifies the finalization or cleanup work that the expiry frees.
- Both claims also wake the ownership worker queue in their transaction,
so a quiet worker watches the new holder (Greptile round 1).
- `ownership-registry.ts`: `native_finalizer_lease` and
`native_cleanup_lease` register `settle`. Their owner is the holder
process; rows without a holder keep the token fence. Listings cover
outstanding leases only.
- `heartbeat/recovery.ts`: restart recovery settles both kinds before it
finalizes and schedules cleanup. A failure is logged and the reconciler
pass retries it.
- Two sparse partial indexes on `lease_expires_at` for the two listings,
so the settle watch re-check stays indexed.

Bespoke code deleted: none. These kinds had no liveness check; their
only release was lease age (the takeover in the claim), which stays as
the fence for unprovable holders.

## Verification

- `cd server && npx vitest run
src/__tests__/heartbeat-native-restart-suspension.test.ts -t
"finalizer|cleanup|holder|exact lease"`: 12 passed (rerun after the
rebase on master). The crash-point test also asserts the ownership wake
for its run; it fails without the signal.
- `cd server && npx vitest run
src/__tests__/ownership-reconciliation-report.test.ts`: 17 passed.
- Red on the base branch (server code at `bea3bfb20b`, tests and schema
from this branch): 7 new tests fail, 5 pass (the 5 are existing tests).
Red: the crash-point restart test, the two reconciler settle tests, the
three live/unprovable counter-cases (owner was a token fence), and the
exact-lease CAS test. The tests were written after the code.
- New tests:
- crash point: a finalizer claim was written and its holder killed
before commit; the next restart finalizes the run, and this boot's claim
stamps itself as holder;
- a dead finalizer or cleanup holder is settled by a recording pass,
never by a read-only pass (`record: false`); the accepted result and
phase are untouched;
- live counter-cases: a live earlier-boot PID (`pid_alive`), the current
boot (`current_process`), a dead PID in another PID space
(`different_process_space`, unprovable) keep the lease through a pass
and a restart;
- a holder written for another token, and a holderless row of the
previous release, stay token fences, also with
`PAPERCLIP_EPHEMERAL_SERVER=true`;
- settle refuses a lease taken over after the proof
(`owner_changed_since_proof`).
- Not run locally: typecheck (CI runs it) and the wide suites.

## Risks

- Previous-release story (rules/upgrade-safe-run-state.mdc): rows saved
by the previous release have no `lease_holder`. They stay token fences
and the existing claim takes them over at expiry. Neither lease outlives
5 min, so this covers at most 5 min after the upgrade. A rollback
ignores the new column.
- Unprovable holders (other host or PID space, unknown space): no
operator action. The lease is short and self-expiring; at expiry the
next claim takes it over and the old holder's next token
compare-and-swap fails. That fence is the handoff. A different host is
never proof.
- The settle only expires a lease. Finalization and cleanup still run
under their own checks (cleanup keeps its maintenance-history proofs).
Settling ownership does not settle the accepted result, workspace
preservation, or accounting.
- Migration adds a nullable column and two partial indexes on a sparse
predicate. Low risk.

DottaandClaude Opus 5.5 7213f64962 fix(heartbeat): write spawn identity and event sequence in one run update (#19954)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The heartbeat records the provider process identity when a native or
legacy run spawns its process
> - This write updated the run row and then reserved the event sequence
with a second UPDATE of the same row
> - PostgreSQL re-checks every foreign key on a row that the current
transaction already changed, so the second UPDATE took KEY SHARE on the
issue, the predecessor run, and the other parent rows
> - A transaction that held one of those rows FOR UPDATE blocked spawn
persistence, and the failed write ended a user's Retry as
`native_session_interrupted`
> - This pull request writes the identity and reserves the sequence in
one UPDATE, and it retries deadlock and serialization failures of the
spawn write
> - The benefit is that a user's Retry no longer fails because an
unrelated transaction holds the issue or the failed predecessor run

## Linked Issues or Issue Description

**What happened**

A user clicked Retry on a failed native run in the
`runs-adapters.inspect-failed-run` chat eval (embedded PostgreSQL, one
server process). The retry run failed with `native_session_interrupted`.
Its error was `Failed query: update "heartbeat_runs" set
"next_event_seq" = "heartbeat_runs"."next_event_seq" + 1 ...`. The query
started at 01:51:04 and failed at 01:51:16. The OpenCode driver awaits
`onSpawn` before its health check, so `native.session.execute` failed
after 12002 ms. The stack showed `allocateHeartbeatRunEventSeq` inside
`appendHeartbeatRunEvent`, called from
`persistHeartbeatRunProcessMetadata`. The process identity was lost
(`processPid` stayed null). The server log does not include the
PostgreSQL cause code.

**Expected behavior**

Spawn persistence must not wait on locks for unrelated parent rows. A
transient deadlock or serialization failure must be retried. It must not
end the run.

**Steps to reproduce**

1. Create a run whose `issue_id` and `retry_of_run_id` point at an issue
and a predecessor run.
2. In a second connection, begin a transaction and run `SELECT ... FROM
issues WHERE id = <issue> FOR UPDATE` (or lock the predecessor run).
Keep the transaction open.
3. Call `persistHeartbeatRunProcessMetadata` for the run.
4. Before this change, the call blocks on the `next_event_seq` UPDATE
until the second transaction ends. If that transaction then waits on the
run row, PostgreSQL reports a deadlock.
`server/src/services/heartbeat/process-identity-persistence.test.ts`
reproduces step 4.

Root cause: `server/src/services/heartbeat/run-lifecycle.ts`
(`persistHeartbeatRunProcessMetadata`) updated the run row, then
`appendHeartbeatRunEvent` called `allocateHeartbeatRunEventSeq`
(`server/src/services/heartbeat-run-events.ts`), which updated the same
row again. PostgreSQL's `RI_FKey_fk_upd_check_required` always fires the
foreign-key checks when the old row version was written by the current
transaction. The checks take KEY SHARE on each referenced row, and KEY
SHARE conflicts with FOR UPDATE.

## What Changed

- `appendHeartbeatRunEvent` accepts a narrow `runUpdate` option (process
identity columns only). `allocateHeartbeatRunEventSeq` applies these
columns in the same UPDATE that reserves the sequence. Deduplicated
receipts (native source, retry exhaustion) reject `runUpdate`, because
they do not allocate.
- `persistHeartbeatRunProcessMetadata` reads the run binding, appends
`native.process_identity_recorded` with the identity as `runUpdate`, and
returns the updated row. The run row now gets one UPDATE in this
transaction.
- New `retryTransientRunWrite` retries SQLSTATE `40P01` and `40001` up
to four times. The lifecycle `persistRunProcessMetadata` and the legacy
cleanup-intent wrapper in `heartbeat.ts` use it. The legacy wrapper
still updates the run row a second time when it records the cleanup
intent, so the retry covers a deadlock there.
- New regression test
`server/src/services/heartbeat/process-identity-persistence.test.ts`.

## Verification

- `npx vitest run
src/services/heartbeat/process-identity-persistence.test.ts` (from
`server/`): 3 passed. Without the `run-lifecycle.ts` change, both lock
cases fail with `expected 'blocked' not to be 'blocked'` after 3 s.
- `npx vitest run src/__tests__/heartbeat-run-event-sequencing.test.ts
src/services/heartbeat/run-lifecycle.test.ts`: 42 passed.
- `npx vitest run src/__tests__/heartbeat-process-recovery.test.ts -t
"<the four tests that call persistHeartbeatRunProcessMetadata>"`: 5
passed.
- `tsc --noEmit -p server`: no errors in the changed files. The only
error comes from a local workspace-link mix in `packages/adapter-utils`,
which this change does not touch.
- I did not run `pnpm verify` or the full suite locally. CI supplies
that coverage.

## Risks

- Low risk. The written columns, the event type, the payload, and the
sequence order do not change.
- The event payload `processStartedAt` now comes from the value that the
transaction writes, not from a re-read of the row. The value is the
same.
- An event insert still checks its own `agent_id` and `company_id`
foreign keys. A transaction that holds the agent row FOR UPDATE can
still delay the spawn write. That wait is the same for every event
writer, and this change does not alter it.
- Other paths that update a run row and then append an event in the same
transaction keep the second-UPDATE foreign-key checks. This change fixes
the spawn identity path that lost the run.

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 f5400e2594 feat(recovery): settle the accepted-result lease on the shared ownership path (#19933)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - A control-plane restart can kill the controller after an agent's
result is accepted. The result then stays leased to a dead process.
> - Today a private sweep (`native-dead-controller-result-lease.ts`,
#19713) proves that controller dead with its own liveness rules.
> - The durable-ownership plan (#19831) replaces private proofs with one
prover (`proveOwnerGone`, #19853) and one registry (#19861).
> - This pull request moves the accepted-result executor lease to that
shared path and deletes the private sweep. It is Phase 2's first kind.
> - The benefit is one tested rule for when a dead owner's result lease
is released, and the reconciler now repairs a lease that restart
recovery missed.

## Linked Issues or Issue Description

Refs #19831 (plan), #19853 (prover), #19861 (registry), #19713 (old
sweep), #19883 (legacy host fallback), #19927 (Phase 2 data).

**What happened?**
The accepted-result lease had its own liveness proof, separate from the
shared prover. The reconciler could only report a dead owner, not settle
it. When restart recovery missed a lease, it waited out the 20-minute
lease.

**What did you expect?**
One prover decides, and both restart recovery and the periodic
reconciler pass settle a lease whose controller is proven gone.

**Steps to reproduce**
1. Accept a native run result.
2. Kill the controller (SIGKILL) and start a new server.
3. If the restart sweep does not see the row, the result stays leased
until the lease expires.

## What Changed

- `ownership-registry.ts`: a kind may register `settle` and
`onUnprovable`. `native_accepted_result_lease` registers both. Other
kinds stay report-only.
- New `native-accepted-result-lease-settlement.ts`: a compare-and-swap
settle that expires exactly the proven owner's lease. It keeps the old
guards: the run must still be `running`, remote copyback stays fenced,
and a lease taken over since the proof is left alone.
- `ownership-invariant-report.ts`: the pass calls `settle` on `gone` and
`onUnprovable` on `unprovable`. A read-only pass (`record: false`) never
settles. New `settleOwnableKind()` for restart recovery.
- `heartbeat/recovery.ts`: restart recovery calls
`settleOwnableKind("native_accepted_result_lease")` instead of the old
sweep.
- Deleted `native-dead-controller-result-lease.ts`.
- `owner-proof.ts`: accepts a board attestation (`operator_attested`).
It also keeps the one-release local fallback for rows saved before their
PID space was recorded, on single-host servers only, and flags each use
so it is logged (`legacy_host_unknown_dead_pid_proof`, #19883). An
ephemeral server returns `unprovable` (`process_space_unrecorded`) and
the existing "confirm the previous server stopped" board action is
raised.

## Verification

- `cd server && npx vitest run
src/__tests__/heartbeat-native-restart-suspension.test.ts`: 27 pass, 7
of them new.
- `npx vitest run src/services/owner-proof.test.ts
src/__tests__/ownership-reconciliation-report.test.ts`: pass.
- Red/green (tests written after the code): 5 new behaviour tests fail
on master and pass here. They cover the ephemeral board action, the
reconciler-pass settle, the live-owner counter-case in that pass, the
legacy marker, and operator attestation. The stamped-dead-controller and
foreign-PID-space cases pass on both, as the old path behaved the same.
- Server typecheck passes (`npx tsc --noEmit -p server/tsconfig.json`).
- Not run locally: the full server suite (`pnpm verify` asks for broad
coverage because a file was deleted). Required CI covers it.

## Risks

- Previous-release story (rules/upgrade-safe-run-state.mdc): NRF rows
saved before #19868 have no `controller_host_hash`. They keep the same
one-release local proof as before on single-host servers, and each use
is logged. On ephemeral servers they stay unprovable and ask the board,
as before. Rows on another PID space keep their lease (the fence), as
before.
- Fail-open risk: settle is compare-and-swap on the lease token, boot,
PID, host hash and start time of the proven owner. An `unprovable` owner
is never released. Live-owner and foreign-space cases are tested.
- No change adds work before `turn.start`.

DottaandClaude Opus 5.5 18644a3263 feat(recovery): instrument 20 durable write boundaries with crash points (#19938)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A control-plane restart between two durable writes leaves an
in-progress record owned by a dead process
> - #19937 added `crashPoint(name)` and a registry of 20 named
boundaries from the Phase 0 inventory
> - A name without a call site cannot fire, so the crash-point suite
cannot test it
> - This pull request puts one call at each registered boundary and adds
a test that keeps the registry and the call sites in step
> - The benefit is that the on-demand suite (next pull request) can kill
the control plane at every known write-ahead gap

## Linked Issues or Issue Description

Refs #19831 (plan, Phase 5). Refs #19846 (inventory, "Write-ahead
coverage"). Stacked on #19937 (helper and registry). Refs #19861
(ownable kind ids).

**Problem**
The registered crash points have no call sites.

**Expected behavior**
Each registered point is called at its gap: after the first durable
write or outside effect returns, before the next one starts. Disarmed
(always in production) each call is one comparison.

**Scope**
Call sites and a coverage test only. The suite runner and CI workflow
follow.

## What Changed

- Server call sites (`@paperclipai/shared/crash-points`):
- `sandbox-creation-operations.ts`: around the provider `create` call
(intent → provider → lease).
- `native-session-executor.ts`: after `native.process_start_requested`,
before spawn.
- `paperclip-control-plane-port.ts`: after the result-accept
transaction, before finalization starts (only when a result was
inserted).
- `native-run-finalizer.ts`: after `commitNativeStatusDecision`, before
the run projection.
- `workspace-operations.ts`: `workspace_finalize` only — after the
running row, and after `settle()` before the done row.
- `environment-runtime.ts`: provider release → lease row; teardown claim
→ destroy; reusable destroy → lease release; stop-and-retain claim →
stop.
- `heartbeat.ts`: lease release → runtime services; budget reservation
hold → dispatch.
- `heartbeat/queue.ts`: run claimed `running` → wake request `claimed`.
- `run-cost-accounting.ts`, `usage-receipts.ts`: accounting commit →
spool unlink; receipt spool → DB row → unlink.
- `packages/paperclip-runner/src/crash-point.ts`: a small copy of the
helper for controller code in this package, which does not depend on
`@paperclipai/shared` (adding that dependency would change the runner
content ID). It arms only `runner.*` names. runnerd never sees the
variable: its environment is an allowlist.
- Runner call sites: after the runnerd spawn, before its identity is
published (both spawn paths); `turn.start` result received → controller
journal saved → next send.
- `server/src/__tests__/crash-point-call-sites.test.ts`: every
registered point has a call site, every call names a registered point,
and every `kinds` entry is an ownable kind id of the Phase 1 registry.

## Verification

- `cd server && npx vitest run
src/__tests__/crash-point-call-sites.test.ts` → 3 passed.
- `pnpm --filter @paperclipai/server typecheck` → clean. `pnpm --filter
@paperclipai/paperclip-runner exec tsc --noEmit -p .` → clean.
- Behavior with nothing armed is unchanged: each call returns at its
first comparison (measured in #19937: about 3.7 ns).

## Risks

- Low risk. No call changes control flow unless `PAPERCLIP_CRASH_POINT`
names it and `NODE_ENV` is not `production`.
- Points on the path before `turn.start` (process start, runner spawn)
cost nanoseconds, within plan invariant 8.
- `usage-receipts.ts`: the persist-then-unlink one-liner became a block
with the same statements in the same order.
- The runner package change gives the runner a new content ID, as any
runner source change does. No persisted run state changes
(rules/upgrade-safe-run-state.mdc).

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, via Claude Code with
tool use (shell, file edits) and a read-only exploration subagent that
mapped the boundaries.

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.

DottaandClaude Opus 5.5 fc6e1b0346 perf(native): keep local Codex and OpenCode runners warm by default (#19888)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - When someone messages an agent, the turn must start fast. Time to
first token (TTFT) is a first-class metric.
> - The Phase 0 baseline (#19846) found that every local turn launches a
new runner and loads the provider session again, because `per_turn` is
the default lifecycle. That made a follow-up message slower than a new
task.
> - Warm runners keep the runner and provider session alive between
runs. #19874 fixed the defect that broke warm OpenCode follow-ups, and
#19879 bounds an idle warm runner whose controller dies.
> - This pull request makes warm the default for local Codex and
OpenCode agents, and migrates existing agents that only carried the old
creation default.
> - The benefit: follow-up TTFT p50 drops from 12.0 s to 4.7 s (Codex)
and from 21.7 s to 4.2 s (OpenCode), with no new restart-chaos failures.

## Linked Issues or Issue Description

Refs #19846 (TTFT baseline), #19852 (startup sub-spans), #19874 (warm
completion contract), #19879 (warm reconnect grace).

**What existing behavior does this improve?**
The default runner lifecycle for native agents, and how a follow-up
message starts.

**Current behavior**
Agent creation writes `lifecycleMode: "per_turn"` into every native
agent. Every follow-up launches a new runner and restores the provider
session: 4.2 s (Codex) and 16.3 s (OpenCode) at p50 before the turn
starts.

**Proposed behavior**
New native agents store no lifecycle. On a local target, an unset
lifecycle resolves to `warm` with the default 5-minute idle window for
Codex and OpenCode. Other harnesses, remote targets and managed
providers without warm support stay `per_turn`. An explicit choice
always wins. Migration 0443 clears the stored creation default from
existing agents, except where an edit set "Turn by turn" explicitly.

**Reason and benefit**
Measured locally (`doc/plans/2026-11-07-warm-follow-up-ttft.md`). Warm
follow-ups are 2.6–5× faster for Codex and OpenCode, and restart
recovery latency is equal or lower.

## What Changed

- `native-lifecycle.ts`: an unset `agentMode` resolves to warm (5-minute
idle window) for local `codex_app_server` and `opencode_server` agents.
`runtime-selection.ts` passes `localTarget`. Explicit `per_turn` or
`warm` wins. An admitted session keeps its persisted policy. ACPX Claude
stays `per_turn`: it relaunches its provider process on every follow-up
by design, so warm did not shorten its follow-up (10.7 s warm vs 10.5 s
per_turn).
- Creation and configuration writes no longer store `lifecycleMode:
"per_turn"` for Codex, Claude or OpenCode. This covers
`normalizePaperclipRunnerAdapterConfig` (runs on every create and
update), `paperclipRunnerTransitionConfig` (switching to the native
runner), `agent-runner-selection.ts`, `codex-local` `build-config.ts`,
and the simplified new-agent setup (`paperclipRunnerCreationLifecycle`
in `@paperclipai/shared`). Grok, Pi and Cursor keep their explicit
value.
- Agent form: the Runner lifecycle field shows the unset state as
"Automatic". "Turn by turn" and "Warm session" remain.
- Migration `0443_native_warm_follow_up_default.sql`: clears
`lifecycleMode = 'per_turn'` from native Codex, OpenCode and Claude
agents unless `agent_config_revisions` shows an edit that set it to
`per_turn`. Each migrated agent gets an `agent.updated` activity entry
with the old value (`actor_id =
migration:native-warm-follow-up-default`). Creation records no revision,
so a "Turn by turn" pick made at creation cannot be told apart from the
old default. The product owner approved migrating those agents. Claude
agents follow the default, which is `per_turn` today.
- Restart chaos harness and TTFT driver: `--lifecycle
per_turn|warm|default` (saved in the wave plan). `default` removes the
catalog's pinned lifecycle, so a wave exercises the real default path.
- Docs: `doc/DEVELOPING.md` "Runner lifecycle default", and the results
in `doc/plans/2026-11-07-warm-follow-up-ttft.md`, which also documents
baseline finding 4 (Claude's resumed turn-start gap is ACPX's per-turn
process generation, not the provider).

## Verification

- `server`: `native-lifecycle.test.ts` (new default cases: local Codex
and OpenCode warm, Claude, remote, unknown target, unmeasured harness,
managed Claude, admitted per-turn session, explicit choices, non-native
adapter), `agent-runner-selection.test.ts`, `runtime-selection.test.ts`
(335 pass).
- `packages/db`: `native-warm-follow-up-default-migration.test.ts` on
embedded Postgres. Default agents are cleared, the explicit edit is
kept, other harnesses and legacy adapters are untouched, audit rows are
written once, and a rerun is a no-op. Without the explicit-edit filter
the test fails. `check:migrations` passes.
- `codex-local` `build-config.test.ts` (65), `ui`
`config-fields.test.tsx` (40), restart-chaos unit tests (134), `tsc
--noEmit` for `server`.
- `adapter-utils` `paperclip-runner-lifecycle-default.test.ts`:
configuration writes and adapter conversion store no lifecycle for
Codex, OpenCode and Claude, keep `per_turn` for the others, and preserve
explicit choices. It fails without the fix.
- End-to-end default check on this branch (`ttft-baseline.ts --lifecycle
default`, codex and opencode, 2 samples): the agents read back with no
stored lifecycle, and every follow-up reused the runner and provider
session (no `runner.process.launch`). Follow-up TTFT was 3.6–4.8 s. This
check found the per-write `per_turn` injection fixed here.
- Restart chaos (codex and opencode, A1/B1/B5, K1/K2/K6, seed 4242), 8/8
PASS each with no open signatures: forced warm, forced per_turn, and
`--lifecycle default` on this branch (agents created without a
lifecycle).
- `pnpm verify` selects broader CI (harness config is a global input),
so required CI supplies the broad coverage.

## Risks

- Behavior change: local Codex and OpenCode agents keep a runner and
provider process for up to 5 minutes after a run. Instance sleep waits
for that idle window. The process is reaped by the idle timer, by
graceful shutdown, or by the #19879 reconnect grace if its controller
dies.
- Migration: agents whose "Turn by turn" was chosen at creation become
Automatic. The activity entry records the old value; choosing "Turn by
turn" restores it.
- Previous-release story (`rules/upgrade-safe-run-state.mdc`): a task
session keeps the lifecycle policy it was admitted with, so sessions
saved before this change stay `per_turn`. New sessions get the default.
No run, checkpoint or launch state changes shape.

DottaandClaude Opus 5.5 5a20fca9f7 fix(recovery): judge an orphaned run's pid only in the PID space that recorded it (#19871)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The orphan reaper (`terminalizeOrphanedRunningRun`) ends a `running`
run whose recorded process is gone
> - It judged "gone" with `kill(pid, 0)` on the local host, wherever the
process actually ran: another host, another PID namespace, or a sandbox
> - So a run whose process is alive elsewhere could be terminalized
while it still works
> - #19868 fixed the same gap for native coordinator takeover and the
runtime-control sweep. This pull request finishes finding 2 for the
reaper
> - The benefit is that a dead local pid never proves an owner on
another host is gone

## Linked Issues or Issue Description

**Bug description**
The Phase 0 ownership inventory (finding 2) names the orphan reaper
`terminalizeOrphanedRunningRun` (`recovery/service.ts`) as a proof that
accepts "the pid is dead here" for a process anywhere. `heartbeat_runs`
recorded `process_pid` with no PID space, and a sandbox pid could
collide with a local one.

**Steps to reproduce**
1. A run records `process_pid` on host A, or in a sandbox.
2. On host B, that pid number is not alive.
3. B's stale-lock sweep terminalizes the run as `orphaned_running_run`.

**Expected behavior**
The process-death authority applies only in the PID space that recorded
the pid. Issue-terminal authority is unchanged.

Refs #19846, follows #19868

## What Changed

- Migration `0442`: add nullable `heartbeat_runs.process_host_hash`.
- `heartbeat/run-lifecycle.ts` `persistHeartbeatRunProcessMetadata`, the
one writer of `process_pid`, stores `currentProcessSpaceHash()` for a
local pid and `"remote"` for a sandbox pid.
- `recovery/service.ts`: the process-death authority runs only when
`process_host_hash` is null (rows saved before this column, for one
release) or `sameProcessSpace` matches.
- Tests: the reaper leaves a dead pid alone for another host, a sandbox,
and an unreadable space, and terminalizes it in this space. The writer
stamps local and remote pids.

## Verification

- `npx vitest run
src/__tests__/recovery-stale-issue-lock-sweep.test.ts`: 46 passed.
- Red before the fix: with the old `recovery/service.ts`, the three
cross-space cases fail (the run is terminalized). Green after.
- `pnpm db:generate` produced `0442_low_salo.sql` (one `ADD COLUMN`),
and the snapshot set was pruned to five. `pnpm --filter @paperclipai/db
check:migrations` passed. Server `tsc --noEmit` shows no errors in the
changed files.

## Risks

- Previous-release story: runs saved with `process_host_hash = null`
keep the previous local proof for this release. That matches #19868,
because stranding in-flight runs at upgrade would be a restart failure.
New rows are strict.
- A run whose process really lived on another host now stays `running`
until issue-terminal authority, its controller lease, or another owner
settles it.
- No new I/O before `turn.start`. The hash is computed at module load,
and the stamp rides the existing process-metadata update.

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

**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 e7936fb1ad fix(heartbeat): gate process-loss retries on the shared failure budget (#19856)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When a server restart loses a run's process, the orphan reaper
decides whether to retry the run
> - `doc/execution-semantics.md` says process loss uses the shared
durable failure retry counter, and `enqueueProcessLossRetry` already
schedules against that budget
> - The reaper still guards on `processLossRetryCount < 1`, but nothing
has written that column since the move to the shared budget, so the
guard does nothing
> - So an exhausted chain still says "retrying once" and skips the
interaction continuation path, and a legacy row with a non-zero counter
is refused a retry it is owed
> - This pull request replaces the dead guard with
`failedRunRetryBudgetSpent`, the budget that the retry actually spends
> - The benefit is one restart budget, read and written in one place,
with honest run messages

## Linked Issues or Issue Description

**Bug description**
The Phase 0 ownership inventory (finding 5) found that
`processLossRetryCount` has no writer and that its only reader is the
reaper guard at `heartbeat/recovery.ts:2675`. The guard always passes
for new rows. For rows written by earlier releases, it refuses a retry
even when the shared failure budget has room.

**Steps to reproduce**
1. Seed a legacy run that a restart stopped before adapter dispatch.
Spend its whole failure retry budget
(`executionRetryAccounting.failureRetries = max`).
2. Run `reapOrphanedRuns()`.
3. The run fails with "Process lost -- server may have restarted;
retrying once", but no retry is scheduled.

**Expected behavior**
An exhausted budget gives no promise of a retry. A legacy counter value
does not block a retry that the shared budget allows.

Refs #19846

## What Changed

- `heartbeat/recovery.ts`: `shouldRetry` now checks
`!failedRunRetryBudgetSpent(run)` instead of `processLossRetryCount <
1`. When the budget is spent, the reaper falls through to
`scheduleInteractionContinuationInfrastructureRetryIfEligible`, which is
what the old guard intended.
- `packages/db/src/schema/heartbeat_runs.ts`: a comment marks
`process_loss_retry_count` as legacy. There is no schema or migration
change.
- Tests: the three cases that used `processLossRetryCount: 1` to mean
"retry already spent" now spend the real failure budget. Two new cases
cover a legacy counter (a retry is still scheduled) and a spent budget
(no "retrying once", `retryEligible: false`, no retry run).

## Verification

- `npx vitest run src/__tests__/heartbeat-process-recovery.test.ts -t
"process-loss|failure budget|bypass unknown process outcomes|immediate
terminal-run cleanup|paused-tree work|restart stopped before adapter
dispatch|reached adapter dispatch"`: 7 passed.
- Red before the fix: with the old `recovery.ts`, both new cases fail.
Green after.
- Server `tsc --noEmit` shows no errors in the changed files.
- The full `heartbeat-process-recovery.test.ts` file (419 cases) stalled
locally at 0% CPU after about 15 minutes. That run was on a worktree
whose package builds were stale at first. I ran the focused subset
instead, and required CI runs the full file.

## Risks

- Low risk. The retry decision now follows the same budget that
`enqueueProcessLossRetry` already enforced. A run with budget left
behaves as before.
- Previous-release story: rows saved with `process_loss_retry_count > 0`
are no longer refused for that reason alone. The shared failure budget,
which earlier releases also wrote, bounds them. The column stays, so
earlier-release readers (`queue.ts` startup resume) keep working.

code execution in Claude Code.

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 a94881d1a7 fix(heartbeat): save a comment refused by a temporary hold and route post-quarantine input to its own gate (#19829)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A user's follow-up comment or Retry must be delivered once,
eventually, even when a temporary company admission hold (accounting
still settling) is active
> - #19741 kept claimed runs queued through such a hold and woke held
work when it cleared
> - A restart-chaos wave still lost a comment, because its wake was
refused before admission and written as a terminal skip
> - The same wave left a Retry waiting forever for a stop record of a
process that never existed
> - This pull request saves the refused comment as a deferred receipt,
and routes input after a pre-launch quarantine failure to the
quarantine's own gate
> - The benefit is that the comment is delivered after the hold, and the
task asks for the action that actually unblocks it instead of offering a
Retry that can never start

## Linked Issues or Issue Description

Refs #19741 and #19702.

**What happened?**
In a restart-chaos wave, a failed run's accounting held the company for
600 s.
1. A user commented while the task's run was live. The enqueue budget
gate refused the comment's wake before it reached the deferral behind
the live run. Because it was a user request with no saved receipt, it
was written as `skipped` (`budget.blocked`). The live run finished
without it and the task ended `done`, so the comment was lost.
2. A Retry created a run that the native cleanup-quarantine fence
refused before it requested any runner launch
(`native_session_cleanup_quarantined`, no process events). A second
Retry then waited with `process_identity_missing` ("The previous run has
no verified stop record") for a process that never existed. The task
kept offering Retry, and that Retry could never start.

**Expected behavior**
A comment refused by a temporary hold stays saved and is delivered once
later. Input after a run that was refused before launch is handled by
the quarantine gate: Retry is not offered (send a new message), and a
new message gets the verified-stop check of the previous provider
session.

## What Changed

- `heartbeat/queue.ts`: when the enqueue budget gate refuses a user's
comment wake and the block is temporary (not a reached hard stop, per
`isBoardOwnedBudgetBlock`), the wake is saved as a
`deferred_issue_execution` receipt. The receipt carries the comment ids
and an `executionWait` of `budget.blocked`, and the gate notifies the
deferred-receipt worker and throws `PersistedExecutionWaitRefusal`. It
is not written as `skipped`. Normal promotion (when the live run ends)
and #19741's hold-release wakeups deliver it.
- `native-local-process-stop.ts`: new `nativeRunRefusedBeforeLaunch`. It
returns true for a failed native run with
`native_session_cleanup_quarantined`, no recorded process, and no
launch-request or identity event.
- `explicit-native-continuation.ts`: such a run passes the
process-identity check, so the existing quarantine branch decides. A
Retry gets `cleanup_quarantined` (shown with `canRetry: false` and "send
a new message"). A new message gets
`verifyStoppedNativeSessionForContinuation`. Any launch request or
identity record keeps the original stop proofs.

- `native-session-executor.ts`
(`verifyStoppedNativeSessionForContinuation`): when the source has no
process record and no launch event, the verifier relies on the previous
owner's stop evidence. Before this change it required the source to
share the owner's process identity, so a new message stayed held even
after the owner stopped. A source that carries a process identity must
still match the owner exactly.

## Verification

Each new test fails on `master` and passes with this change, on embedded
Postgres:
- `server/src/__tests__/heartbeat-held-comment-wake.test.ts`: a comment
whose wake the hold refuses at enqueue is saved with a `budget.blocked`
wait and is not skipped. It is delivered exactly once after accounting
settles.
- `server/src/services/explicit-native-continuation.test.ts`:
- A run refused by the quarantine before launch routes a new message to
the quarantine's stop verification and a Retry to `cleanup_quarantined`.
These failed on `master` with `process_identity_missing`.
- Guards (green on both): a quarantined run that requested a launch, and
another failure without a process record, still require
`process_identity_missing`.
- `server/src/services/quarantined-task-retry.test.ts`: a never-launched
quarantined source is certified once the previous owner has stopped (red
on `master`). It stays held if the source requested a launch or the
owner is still running. All 31 tests pass, and the `stopped native
conversation physical cleanup` suite passes (46).
- Related suites pass locally (6 files, 620 tests): explicit native
continuation, held comment wake, queued comments routes, comment wake
batching, refused assignment wake, deferred receipt work. Two
`deferred-execution-receipt-work` tests failed once under parallel load
and passed when run alone.

## Risks

- The saved-comment path applies only to user comment wakes refused by a
temporary budget hold. Hard stops, system wakes, case handoffs, durable
chat requests, and existing saved receipts are unchanged.
- The pre-launch rule is limited to the quarantine failure code with no
launch evidence. Every other missing process identity still requires the
existing stop proof.

## 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,
kept restart-chaos instance inspection).

DottaandPaperclip 384fa2b7be Allow context compaction while Agent Chat waits (#19801)
## Thinking Path

> - Paperclip manages agents and their work.
> - Agent Chat can wait for a user between useful turns.
> - The task Properties panel already lets that user request context
compaction.
> - The queue treated that maintenance request as an ordinary wake and
refused it while the chat waited.
> - Compaction must maintain that session without starting a new
conversation turn.
> - This change admits the authenticated request, preserves the waiting
state during execution, and prevents competing requests from saving
extra maintenance work.
> - Ordinary and unauthorized wakes remain blocked.

real compaction service reaches the heartbeat queue, receives no run,
and reports that compaction did not start.

**Expected behavior**

The authenticated owner can request one separate compaction run while
the chat waits. The request must keep its existing actor, task, agent,
budget, and execution checks. Ordinary waiting-chat wakes must stay
blocked.

**Steps to reproduce**

1. Use an open Agent Chat conversation whose agent supports compaction.
2. Wait until the conversation is waiting for its owner.
3. Request Compact now from the task Properties panel.
4. Observe the refusal before this fix. The new database regression
calls the real compaction service and queue to reproduce it.

## What Changed

- Admit only the existing complete manual compaction envelope. Require a
user actor, no coalescing, the compaction intent, and matching nonempty
request IDs.
- Preserve the waiting conversation state, session generation, reply
boundary and unanswered questions in the existing conversation
preparation owner.
- Recheck active and deferred maintenance under the existing issue
admission lock. Competing clicks cannot save a second maintenance
request.
- Add execution coverage with and without a pending question. Add
concurrent admission and deferred-request controls, including admission
after the pending receipt is cancelled. Keep the existing authorization
and ordinary conversation controls.

## Verification

- The original service-to-queue request failed before the admission fix.
- The execution regression then caught the review finding: compaction
succeeded, but both waiting-state controls failed. The same complete
controls passed after the conversation preparation fix.
- A real concurrent request test recorded two durable maintenance
receipts before the atomic admission fix. It counts deferred authority
as well as admitted runs.
- Current integrated candidate: normal current Runner core and surface
TypeScript exports passed. All seven normal App typecheck programs
passed. The whole queue/execution suites passed 86/86, the whole
context-compaction suite passed 5/5, and 11 selected ordinary
conversation controls passed. There were 102 actual passes; the 29
unselected conversation cases are not counted as passes.
- Database controls use fresh dedicated PostgreSQL 17 databases, Node
24, one test worker and pools capped at four. Private fixture adapters
use the existing dedicated database and normal migrations. They keep
test bodies, assertions and time limits intact.
- Earlier fixture and setup failures remain recorded separately from
product failures. These include an omitted external URL, an invalid
closed-task fixture, a missing crypto import, an incorrect
result-envelope matcher, and an unavailable test-library helper. Each
was corrected at its owning boundary. A test-output text matcher also
missed Vitest's abbreviated failure; the raw assertion stack and failure
were retained.
- Local session tests exercise the actual admission, native Runner
lifecycle, accepted result and persisted conversation state through the
supported test backend. They do not prove live provider compaction, UI
rendering or deployed suspension.
- Exact-head remote CI passed: 59 successful checks, three intentional
skips and one neutral check. Greptile and Ponytail both reviewed this
head at 5/5 with no actionable findings. Ponytail explicitly marked it
Ship.
- Master advanced during review. A local merge evaluation preserves
every unrelated master change and all four PR files. The current App
programs and all three execution controls passed again on that projected
squash tree to check the workspace-finalization seam.

## Risks

The change affects admission and preparation for one maintenance
request. A broad exception could start ordinary work or reopen a waiting
chat. The request therefore keeps the complete existing manual envelope
and authorization checks. Conversation preparation still checks the
session generation. The existing issue lock owns duplicate admission.
There is no new timer, database migration or provider protocol.

## Model Used

OpenAI Codex based on GPT-6 managed the change and reviewed the shared
queue fix. OpenAI `gpt-6.1-sol` authored the focused regression
coverage. Both used reasoning, repository tools and local code
execution. The runtime did not expose the context-window size.

Devin FoleyandPaperclip bf12b2d8ad fix: retry reviewed chat setup after temporary contention (#19787)
Retry reviewed chat preparation with the original accepted input.

Bound retries for authorization proof waits that expire before provider
work. Preserve the original answer receipt and queue later wakes
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
browser tests, and all server source/test typecheck layers passed. The
plan approval regression was reproduced on the previous head before the
fix. All applicable CI passed and exact-head Greptile Apex scored 5/5.

DottaandClaude Opus 5.5 6adc8b1049 fix(recovery): keep restarted Retry attempts as task directories and settle failed re-preparation (#19759)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Task recovery lets a user click Retry after a run fails, and a
native run restarts its own preparation after a control-plane restart
> - A Retry for a task without a project runs in a fresh task directory
under `isolated-workspace-attempts`
> - When a restart hit that Retry during bootstrap, preparing it again
treated the task directory as the base of a new git worktree and failed
> - The failed run then kept its native recovery claim open, so the task
showed Retry but every Retry click created no run
> - This pull request keeps the restarted attempt in its task directory
and settles a failed re-preparation
> - The benefit is that a Retry finishes after a restart, and a failed
one can be retried again

## Linked Issues or Issue Description

Refs #19666

**What happened?**
A task without a project failed after a restart
(`native_session_interrupted`). The user clicked Retry. The Retry run
started in a fresh task directory. A restart hit it during bootstrap.
Restart recovery prepared the same run again and failed with
`workspace_validation_failed`: "requested isolated_workspace with
git_worktree, but base workspace
`.../isolated-workspace-attempts/<company>/<issue>/<run>` is not a git
checkout". The task rested blocked with Retry shown. A later Retry click
created no run: the receipt stayed deferred with "New work must wait
while a native run recovers its unfinished accounting." A second storm
wave showed the same failure on a Claude C1 task.

**Expected behavior**
Preparing a run again after a restart reuses the task directory that run
already bound. A git worktree base is only the project's checkout or the
task's own worktree. A run whose re-preparation fails leaves a working
Retry.

**Paperclip version or commit**
`master` at `51eb4ff705` and `131b566ca4` (both include #19666).
Restart-chaos waves on 2026-11-07.

**Steps to reproduce**
1. Use a task with no project and isolated workspaces enabled. Let a
native run fail after a restart.
2. Click Retry. The run starts in
`isolated-workspace-attempts/<company>/<issue>/<run>`.
3. Restart the control plane while the run bootstraps.
4. The re-preparation fails with `git_worktree_base_not_git_checkout`.
Click Retry again: no run starts.

Root cause:
- `server/src/services/fresh-workspace-continuation.ts`
`readFreshWorkspaceReadiness` returns `null` for a native run that
already has admitted input and a bound workspace (from #19693). This is
correct: the restart must resume the admitted workspace.
- `server/src/services/heartbeat/environment-selection.ts`
(`boundTaskDirectory`) excluded every native recovery binding from the
task-directory path. With readiness no longer fresh,
`useIsolatedTaskDirectory` was false. The default `isolated_workspace`
strategy (`git_worktree`) applied, with the task directory as its base.
- The restart recovery claim set the native coordinator to `observed`
with its lease owner. `failRunSetup` failed the run, but nothing
released that claim. `budgets.ts` reads an open coordinator as
unfinished accounting, and Retry admission reads it as
`controller_settling`.

## What Changed

- Environment selection treats a native recovery binding as the task
directory when it is the task's current binding and a bound isolated
task directory. The directory strategy is kept; it never becomes a git
worktree base. A recovery binding the issue no longer points to keeps
its existing path.
- New `settleFailedNativeRecoveryPreparation`. When a
`bootstrap_incomplete` or `resume_dead_runner` restart claim fails its
re-preparation before any provider dispatch, it settles the claimed
coordinator as `terminal_failure` and wakes deferred work. It only
changes a coordinator that is still `observed`, owned by that claim,
without a result, for a failed run. Reattach claims (live runner) are
not changed.
- `doc/task-recovery.md` describes both rules.

## Verification

- `environment-selection.test.ts`, RC-58 cases: a restarted fresh
attempt bound to the task re-prepares as its task directory
(`useIsolatedTaskDirectory` true). It failed before the fix and passes
now. A binding the issue moved away from keeps the old behavior.
- `native-runtime/native-recovery-preparation-failure.test.ts` (embedded
Postgres): before settlement, Retry admission reports
`controller_settling` (the dead Retry). After settlement the coordinator
is `terminal_failure` with the run's error code, and admission no longer
waits on the controller. Settlement is idempotent. Another owner, a
reattach claim, a run that is not failed, and a coordinator finalizing
elsewhere are left unchanged.
- Local regression: `environment-selection`, `workspace-preparation`,
`retry-workspace-continuity`, `native-recovery-preparation-failure`,
`explicit-native-continuation` (588 tests passed).
- Restart-chaos: local restart-chaos runs on `3a7abef4e5` passed, but
neither one reproduced the exact failure (a restart during the Retry's
bootstrap). The race depends on timing, so the unit tests above are the
red/green proof for both defects.
- `--replay w-20261107T011010-s7403/t02` (codex C1 K4 with the original
fault sequence): PASS, R1-R6 and T. The replay's Retry did not cross a
bootstrap restart.
- Wave `w-20261107T064432-s7210` (codex+claude, C1+B1, K1/K4/K6,
`--triggers retry`, concurrency 2): 8/8 PASS. It had 4 Retries,
including C1 tasks with a fault fired right after the Retry click. No
`git_worktree_base_not_git_checkout` and no dead Retry. The server log
has no "incomplete native runner bootstrap" restart in this wave either.
- `ce7e3f9b19` registers execution work before the settlement writes
(Greptile finding).

## Risks

- A native recovery now re-prepares a bound task directory through the
task-directory path. That path still validates the binding, owner,
status and directory identity before use.
- Settling a failed re-preparation ends that run's recovery claim. It
applies only when the previous runner is verified gone
(`bootstrap_incomplete`, `resume_dead_runner`) and no provider dispatch
started in this attempt. A Retry still passes its normal stop, ownership
and admission checks.

## Model Used

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

DottaandPaperclip ae2d2956b3 Reject relative local Runner paths before native admission (#19776)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Heartbeat selects the runtime that will execute a task.
> - A new local Native run uses the controller's Runner binary setting.
> - A relative binary path is invalid. The resolver already rejects it,
but that check occurs after Native admission.
> - This pull request checks the same setting before it creates Native
execution authority.
> - Remote providers and admitted Native recovery keep their existing
behavior.

## Linked Issues or Issue Description

**What happened?**

A relative `PAPERCLIP_RUNNER_BINARY` setting can reach local Native
admission before the binary resolver rejects it. The run has transferred
preparation ownership even though this setting cannot start the local
Runner.

**Expected behavior**

Reject this invalid setting before creating a completion contract or
Native coordinator. Keep the existing preparation owner and the run row
unchanged.

**Steps to reproduce**

Set `PAPERCLIP_RUNNER_BINARY=relative-runner`. Select a new local
`paperclip_runner` Native run. The selection must report the existing
absolute-path error before Native admission.

Refs: #19466 and #19340. Those merged changes repair Retry authority and
saved-workspace recovery. This change only moves local path validation
before new admission.

## What Changed

- Add a pure absolute-path check beside the existing binary resolver.
Both use the actual controller environment setting.
- Run that check before a new local Runner admission. Skip remote
execution, API-only providers, and an already admitted Native run.
- Test the rejection, unchanged preparation ownership, controller
setting selection, remote behavior, and immutable recovery. Keep the
existing resolver checks.

## Verification

- The full binary test file passed: 32 tests.
- The full runtime-selection file passed against a dedicated PostgreSQL
database: 62 tests. It exercises real admission transactions, contracts,
coordinator rows, and instruction-copy controls. It replaces context
materialization and remote workspace synchronization at their existing
test boundaries.
- After normal integration with current master, the normal Shared/SDK,
database, eval-kernel and Runner builds passed, together with all seven
normal application TypeScript programs. The original
recovery-preparation case passed again on this integrated revision
against a fresh dedicated database (1 passed; 61 filtered). The earlier
full 32-test binary and 62-test selection results carry only where their
source and executed boundaries are unchanged.
- The first private selection wrapper failed during module resolution,
before any case or database use. A TypeScript wrapper with the same body
recovered that setup failure. This was not a product regression.
- Reproduce with `pnpm --filter @paperclipai/server exec vitest run
src/services/native-runtime/native-codex-runner.test.ts --maxWorkers=1
--no-file-parallelism`.
- Set `PAPERCLIP_RUNTIME_SELECTION_TEST_DATABASE_URL` to a dedicated
disposable test database before running `pnpm --filter
@paperclipai/server exec vitest run
src/services/heartbeat/runtime-selection.test.ts --maxWorkers=1
--no-file-parallelism`.

## Risks

- This check validates path syntax only. An absolute path can still fail
the existing file-access or artifact checks later.
- A wrong branch condition could reject remote or existing Native work.
The tests cover these exclusions.
- This does not prove that a real provider can start or that a deployed
service is healthy. It changes no database schema or retry authority.

## Model Used

OpenAI `gpt-6.1-sol` through Codex, with source inspection and
code-execution tools. The host does not expose the context-window size.

DottaandClaude Opus 5.5 b03ea621c6 fix(environments): retry a teardown interrupted by server death at once (#19749)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - After a remote run, Paperclip destroys its provider sandbox. The
teardown first claims the lease with a 15-minute ownership fence, so no
other cleanup runs at the same time
> - #19696 made restart recovery end a fence when the claiming server
process is proven to have exited. It only does that for claims that
record the claimer
> - The run-release teardown and the stop-only teardown did not record
the claimer
> - When the server died during a run-release teardown, the sandbox
therefore stayed up until the 15-minute fence expired
> - This pull request records the claimer on those claims, and stops a
teardown attempt lost to a dead server from counting as a failed attempt
> - The benefit is that a restart during sandbox teardown destroys the
sandbox at the next startup sweep

## Linked Issues or Issue Description

**What happened?**
In a Daytona restart chaos wave, a run finished at 05:34:48. Its release
claimed the lease and called the provider, and a SIGKILL stopped the
server 2 seconds later. After restart the lease stayed `pending_cleanup`
with an in-flight claim. The sandbox was destroyed at 05:49:49, when the
15-minute claim fence expired. There was no provider error.

**Expected behavior**
A teardown interrupted by the server's death is retried by the next
startup sweep. It is not counted as a failed attempt. A real provider
error keeps the normal backoff.

**Steps to reproduce**
1. Release a run's sandbox lease with destroy, and hold the provider
call.
2. Stop the server during the provider call.
3. Restart. On master, the sweep skips the lease until the fence expires
15 minutes after the claim.

Refs #19696.

## What Changed

- `environment-runtime.ts`: the run-release teardown claim
(`destroyClaimedSandboxLease`) and the stop-only teardown claim save
`pendingCleanupController`, bound to the claim's attempt id, the same
way sweep claims do since #19696.
- `heartbeat/recovery.ts`: sweep claims mark that they counted an
attempt. When the sweep ends the fence of a lost claim, it gives that
attempt back, so a teardown lost to a dead server does not move toward
the cap or the long cooldown. Claims from other paths did not count an
attempt, so nothing changes for them.
- Workspace-repair and export-retry fences are unchanged. They protect
workspace work, not teardown.

## Verification

- Red, then green:
- `environment-runtime.test.ts` → "retries a run-release teardown at the
next sweep after the releasing server dies". The provider call is held
during `releaseRunLeases(..., "destroy")`, the claim is marked as from
an exited server, and a restarted sweep runs. On master the claim has no
controller record and the sweep skips the lease. With the fix, the sweep
destroys it at once and records attempt 1.
- `heartbeat-pending-cleanup-sweep.test.ts` → "does not count a sweep
attempt lost to a dead server as a failed attempt". On master the retry
is recorded as attempt 4; with the fix it is attempt 3 again.
- `environment-runtime`, `heartbeat-pending-cleanup-sweep`,
`sandbox-creation-operations` and `environment-routes` pass (367 tests).
`tsc --noEmit` for `server` passes.

## Risks

- The proof that a claimer exited is the same-PID-space proof from
#19696. A live, foreign or unidentified claimer keeps its fence.
- Giving back a counted attempt applies only after that proof. A
teardown that fails with a provider error still counts and backs off.
- No schema change. The new fields live in existing JSON metadata.

96bc021edb fix(server): certify settled legacy processes for future retries (#19377)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Bounded retries must preserve current authority, budgets and
deadlines.
> - The tenant can wait for supported future work after the source
process and its cleanup stop.
> - Retained process identity alone cannot prove that cleanup finished.
> - This change records host-owned settlement and checks its exact
identity before a retry can cover its wait.
> - Uncertain process state, changed authority, live claims and cleanup
debt keep the tenant awake.

## Linked Issues or Issue Description

Refs #19001. Related dependencies: #19019 and #18988. Related #19340
covers explicit Native task Retry; this change covers future Legacy
process retries.

Current integrated source: `1645970a9322d1213ba25fc7b52366c285682977`,
normally merged with actual master
`131b566ca4fa866c4348739c75cfe48c805b3398`. The prerequisites above are
merged. This PR targets `master`.

**What happened?**

A future issue, company or review retry can retain its failed source
process identity. The deadline reader could not prove that host cleanup
finished. Supported waits stayed blocked. Ordinary issue retries also
needed an exact source-settlement check, and represented coalesced
requests needed exact input coverage.

**Expected behavior**

A supported future retry covers only its existing wait, under current
company and actor authority, after exact host settlement. Missing,
malformed, stale, cancelled, Native or unfinished source state stays
blocked. No retry gains new execution authority.

**Steps to reproduce**

Fail an ordinary process or fail environment preparation before adapter
entry. Let normal cleanup schedule the existing retry. Inspect its
settlement and deadline, stop and reconstruct the owner, and admit one
useful successor at the saved deadline. Hold cleanup or change authority
to verify that the reader refuses coverage.

## What Changed

- Add nullable internal `legacyProcessSettlement` state through normally
generated migration `0439_cultured_impossible_man`. No backfill or
adapter result creates the record.
- Write exact host settlement after stopped-process and cleanup checks.
Compare the current run and reject live claims or cleanup debt. Optional
persistence failure preserves normal cleanup and keeps sleep coverage
blocked.
- Add a separate preparation receipt for a claimed Legacy run that
failed before any adapter or Native dispatch. Require the same boot, run
times, preparing stage, released claim and completed cleanup. A null PID
alone proves nothing.
- Clear settlement on a new claim, process metadata or Native selection.
Omit the internal record from public serialized data.
- Check exact source lineage and current authority for ordinary issue,
company and taskless retries. Cover completed coalesced requests only
when the admitted retry represents their exact inputs.
- Add the closed `current_review_retry` wait with current reviewer,
stage and existing issue authority checks. Require a nonempty current
stage ID.
- Add actual producer, cold reconstruction, SQL negative, redaction and
optional-persistence controls.
- Repair CI fixture expectations for the additive column, startup mock,
budget owner and popup return URL. Bind the controlled Native comment
server explicitly to loopback.
- Replace temporary Slack clock logging with an exact persisted-deadline
assertion. Wait until that real deadline before the existing single
default poll. Keep both forced polls, business assertions and timing
limits.

## Verification

- On final integrated source `1645970a`, normal Shared/SDK
prerequisites, Runner TypeScript and the entire normal App layered
typecheck pass. Tracked source and lockfile remain unchanged.
- All 26 whole-file settlement, recovery-reader and bootstrap controls
pass. Seven separate real PostgreSQL producer/negative cases pass at
`cf16c6a`; each has one selected passing case and 18 filtered
registrations. Filtered registrations are not acceptance.
- Master then changed the preparation source-lock scope. Its three
intersecting cases were rerun on final `1645970a`: an actual failed
company process, an actual failed ordinary issue process, and held
preparation cleanup. Each preserves its source identity and original
deadline and admits one useful successor. Issue and preparation cases
exercise normal automatic retry; the company case uses the normal
explicit bounded-retry producer.
- The unchanged 26 controls and four other PostgreSQL cases retain their
`cf16c6a` proof after a scoped source comparison. Optional
settlement/preparation persistence failures keep certification blocked
while normal cleanup completes. An entered adapter without process
identity stays uncertified. This is scoped carry, not a claim that every
earlier case ran again on the final head.
- All recorded test owners and controlled groups closed. Final read-only
SQL audits returned no test sessions. One earlier postcase resource
barrier observed a transient unattributed database backend; that
database and original evidence remain preserved. Its later disappearance
is recovery, not an explained cause. No assertion, deadline or test body
was relaxed.
- Migration0439 was generated normally after master history. All
executable SQL and journal history are preserved; the five retained
snapshots are0435–0439. Every Legacy-owned patch and unrelated
actual-master blob/mode is preserved.
- Published exact head `1645970a9322d1213ba25fc7b52366c285682977` passes
all current required checks: 68 successful contexts and eight expected
skips after exhaustive pagination and superseded-run accounting. The
fresh complete Greptile review scores this exact head 5/5. All four
inline review threads are resolved. The latest Ponytail turn stopped
without a verdict; one normal retry was requested, with no active turn
or new finding observed. No old-head score is used. The original
old-base policy failure, its dependent aggregate failure, and the
corrected description-gate failure remain recorded. No full local
repository suite is claimed; remote typecheck, test and build gates
pass.

To repeat the real database coverage, set both
`PAPERCLIP_RECOVERY_DEADLINES_TEST_DATABASE_URL` and
`PAPERCLIP_RECOVERY_DEADLINES_TEST_ADMIN_DATABASE_URL` to the same fresh
dedicated test database and run the selected
`recovery-deadline-acceptance.test.ts` cases with one worker. An unset
URL, skipped case or filtered registration is not acceptance.

The fixtures use controlled local processes and real PostgreSQL.
Reconstruction creates new service owners inside the same test process.
They do not prove deployed Cloud alarms, physical host/database
suspension, new-host recovery or Native capacity settlement. The
original30-second retry remains below the Cloud270-second minimum wake
lead.

The merge projection also includes actual master
`c3180398faca815fed7a62674bd4b0c4e88884ae`, whose common completion path
now sends deferred/recovery notifications. Its unpublished normal merge
tree is `16b028d57150f8caa576e913f38343a365b542dd`. Normal Shared/SDK,
Runner TypeScript and the full App graph pass on that combined source.
One unchanged ordinary-issue acceptance case was rerun there: an actual
failed process retains the original automatic retry deadline, admits one
useful successor, and passes the settlement, authority and no-duplicate
assertions. It passed in 45.055 s; 18 filtered registrations are not
acceptance. All known owners and groups closed, and the independent
final database audit found zero remaining test sessions. The successful
database was removed normally. Recorded worker socket peak is
unavailable for this run; parent-process zero values are not used as
worker measurements. All 29 Legacy-owned paths and every unrelated
master blob and mode are preserved.

Two outside-diff review observations concern existing waiting-chat
compaction and cross-host Native result-lease recovery. Their files are
byte-identical to current master. This focused Legacy change does not
fix or qualify those separate paths.

## Risks

Settlement proves exact local closure. It does not cover live provider
work, Native ownership, cancellation, costs, claims, cleanup debt or
changed authority. Independent checks remain.

Ship normal migration0439 with the reader and writer. Preserve
executable history and the newest five snapshots0435–0439. Generate the
MCP child's next migration normally after this parent.

The prerequisites are merged; the final remote checks must use this
integrated exact head. This proof uses controlled local processes and
external PostgreSQL. It does not establish deployed Cloud alarm
acceptance, physical host or database suspension, cold host recovery, or
R5 Native capacity settlement. The30-second retry is below the Cloud
minimum wake lead.

This focused repair follows the roadmap's bounded recovery and Cloud
deployment work. It adds no new provider policy.

## Model Used

OpenAI `gpt-6.1-sol` assisted with readers, fixtures, source review and
verification through Codex. A coordinating GPT-6-family agent
implemented and reviewed shared lifecycle wiring and integration. Tools
included Git, native TypeScript checks and controlled tests. Exact
served revisions and context limits were not exposed.

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,
live restart-chaos replays).

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.

DottaandClaude Opus 5.5 c97c0dd248 fix(workspaces): give run preparation its own source lock scope (#19734)
<!-- Write all pull request text in Simplified Technical English
(ASD-STE100): short sentences, one instruction per sentence, simple
approved vocabulary, and the active voice. -->

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A run prepares its task workspace under per-source advisory locks
(`workspace-source-lock.ts`). The locks live in a transaction on a
dedicated connection. An `AsyncLocalStorage` scope lets nested calls
reuse that transaction.
> - Timers and detached promises keep the async context that created
them. A native recovery timer or dispatch can start a run from inside
another operation's source scope.
> - When that run prepares its workspace, it sees the other scope as
"held". If that scope already committed, its dedicated connection is
closed. The lock query then fails with `Failed query: select
pg_try_advisory_xact_lock(...)` and cause `CONNECTION_CLOSED`. If that
scope is still open, the run's lock is tied to the other transaction and
is released early.
> - In a restart chaos wave, a reattached follow-up run failed setup
this way 50 ms after "Recovering the existing native runner process".
The setup-failure log did not show the driver cause.
> - This pull request makes only a live scope count as held, and makes
run workspace preparation take its locks in an independent scope.
> - The benefit is that a recovered or dispatched run gets its own
source lock, and a lost-connection failure is diagnosable from the log.

## Linked Issues or Issue Description

**What happened?**
After a control-plane restart, a native run was reattached
(`reattach_remote_runner`). Its workspace preparation failed at once
with `Failed query: select
pg_try_advisory_xact_lock(hashtextextended($1, 0)) as acquired params:
isolated_repository_source:<company>:<issue>`. The run ended
`failed`/`setup_failed`. The stack showed the "already held scope"
branch of `withWorkspaceSourceLocks`, not a new acquisition. The same
failure occurred earlier in the same wave on a different issue without a
restart.

**Steps to reproduce**
1. Call `withIsolatedRepositorySourceLock` for issue A. In its action,
start a detached promise that later calls
`withIsolatedRepositorySourceLock` for issue B.
2. Let the outer action return so its transaction commits.
3. Let the detached call run. It fails with `Failed query ...
pg_try_advisory_xact_lock`, cause `CONNECTION_CLOSED`.

**Expected behavior**
Work that starts after a source scope ends, or independent work such as
a run's preparation, acquires its own locks on its own connection.

**Environment**
Restart chaos campaign on Daytona (OpenCode, workload C1, fault K1,
comment trigger), embedded Postgres. Reproduced locally on embedded
Postgres by the new tests.

Related: #14910 (deferred comment wake reopens a closed issue). This PR
does not change wake promotion.

## What Changed

- `server/src/services/workspace-source-lock.ts`: a scope has an
`active` flag. The flag is cleared when its transaction ends.
`withWorkspaceSourceLocks`, `retainManagedProjectSource`,
`retainCurrentWorkspaceSource`, and `assertCurrentWorkspaceSourceHeld`
use only a live scope.
- `server/src/services/workspace-source-lock.ts`: new
`withIndependentWorkspaceSourceLocks`. It acquires locks in a new scope
and ignores an inherited one.
- `server/src/services/heartbeat/workspace-preparation.ts`: run
workspace preparation uses `withIndependentWorkspaceSourceLocks`.
- `server/src/services/heartbeat/run-completion.ts`: the "heartbeat
execution setup failed" log records a bounded driver `causeCode` (for
example `CONNECTION_CLOSED` or a SQLSTATE). It does not log the cause
text.
- Tests: two embedded-Postgres tests in
`isolated-remote-workspace-source-lock.test.ts`, one unit test in
`run-completion.test.ts`.

## Verification

- `cd server && npx vitest run
src/services/isolated-remote-workspace-source-lock.test.ts` — 4 passed.
- Red (old scope rule): "gives work detached from a finished scope its
own source lock" failed with `Failed query: select
pg_try_advisory_xact_lock(...)`, cause `CONNECTION_CLOSED`. This is the
production error.
- Red: "keeps an independent preparation's lock after the scope that
started it commits" failed because the lock was released with the other
transaction.
- `cd server && npx vitest run
src/services/heartbeat/run-completion.test.ts` — 95 passed.
- `cd server && npx vitest run
src/services/remote-workspace-online-source.test.ts
src/services/heartbeat/workspace-preparation.test.ts
src/services/isolated-repository-rehome.test.ts
src/services/isolated-task-directory-retention.test.ts
src/services/isolated-task-directory.test.ts
src/__tests__/execution-workspace-reopen.test.ts` — all passed.
- `cd server && npx tsc --noEmit` — clean.
- No live Daytona replay was run.

## Risks

- Low. A nested call inside a live scope behaves as before.
- A call that inherited an ended scope now opens its own dedicated
connection and lock transaction. Before, it failed.
- Run preparation never joins another operation's lock scope. No caller
relies on that today. If one did, it would now take a second,
independent lock and could see `workspace_source_busy` instead of
silently sharing.

## Model Used

tool use (shell, file edit, embedded Postgres tests).

DottaandPaperclip 9efee7ee16 fix(runtime): save dynamic skill bundles before native admission (#19729)
## Thinking Path

> - Paperclip manages agents, tasks, and their saved execution state.
> - A replacement server must restore each admitted skill from shared
storage.
> - Installed company skills already have immutable versions.
> - Connector skills add assigned resources and tool definitions for
each run.
> - Those dynamic bytes keep a null version ID and differ from the
static skill.
> - Native admission saved their input before it saved a durable package
receipt.
> - This change stages the exact packages first and publishes the input
and receipt together.
> - A new connector turn can then survive an empty server home.

## Linked Issues or Issue Description

Refs #19675 for the existing runtime asset preservation owner.

**What happened?**

A new native run with an assigned Slack connector creates a concrete
local skill bundle after the old runtime assets were migrated. Admission
saves its execution input without a preservation receipt. The new run
creates a local durability dependency again.

**Expected behavior**

With S3 configured, the exact dynamic bundle must be durable before the
execution input becomes visible. Its null version ID and admitted bytes
must remain unchanged. Local storage must keep its volume-backed
behavior.

**Steps to reproduce**

1. Configure S3 and a native agent with an assigned Slack resource.
2. Prepare a new native task through the normal runtime selection owner.
3. Inspect its runtime skill receipt or restore its skills with an empty
server home. The previous owner saved no receipt.

**Paperclip version or commit**

Reproduced on master `d1ee25d0f7`. The fix is tested on `4a3396d9b9`.

**Deployment mode**

S3-configured server. Local tests use PostgreSQL 18.1 and a private disk
transport with the S3 receipt contract.

## What Changed

- Extend the existing runtime asset owner with package staging and
transaction-bound receipt validation.
- Stage exact unversioned skill packages before native admission. Keep
storage I/O outside the run transaction.
- Publish the frozen input and receipt together under the existing run,
cancellation, and package collection locks.
- Reject changed input bindings and retired package metadata.
- Reuse valid same-run receipts without reading the previous host's
bundle path or requiring a new object read.
- Keep existing online preservation and local storage behavior.
- Add a bounded preparation span and document its work.

## Verification

- Genuine unchanged-production RED: the actual Slack overlay and real
admission transaction save no preservation receipt.
- Final rebased head: 68 tests pass in three suites in 25.36 seconds.
These include all runtime-selection, runtime-preservation, and connector
controls.
- The new positive checks that no execution input or coordinator is
visible during package readback. It restores exact skill and tool bytes,
modes, digests, and null version IDs in a cold home.
- Guards cover an uncertain storage failure, cancellation during upload,
a changed binding, retired package metadata, and local mode. An existing
receipt remains usable after removing the original bundle and during a
storage outage.
- The canonical PostgreSQL wrapper uses one owned disposable PostgreSQL
18.1 container. Each suite's database is cleaned up. Real package
archives, streams, and readback run locally; no external provider or
model is called.
- Strict server TypeScript, module boundaries, changed-line private-data
checks, and `git diff --check` pass.
- [Final-head
CI](https://github.com/paperclipai/paperclip/actions/runs/42337473062)
passes all required build, typecheck, test, and Runner gates. Fresh
Greptile is 5/5 with no open review threads.

## Risks

New S3-backed admission now requires its dynamic packages to be saved
before execution can proceed. A storage failure can therefore stop
preparation. Existing resource cleanup keeps its authority. Failed or
cancelled staging retains original files and the package owner's pending
receipts. Same-run recovery retains its original capture provenance and
cache behavior. The tests replace the external S3 transport; they do not
qualify live S3 permissions or provider execution. No schema, API,
workflow, company skill version, or provider protocol changes are
included.

## Model Used

OpenAI Codex (GPT-6 family; the exact runtime model ID and context
capacity are not exposed in this session), with reasoning, repository
editing, code execution, and tool use.

DottaandClaude Opus 5.5 aed053633e fix(environments): run pending sandbox cleanup when an environment is deleted (#19716)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Operators delete a sandbox environment, optionally with consent to
destroy its sandboxes (`DELETE
/api/environments/:id?destroyReusableSandboxLeases=true`)
> - A sandbox whose teardown failed or was interrupted is kept as a
`pending_cleanup` lease, and it blocks the delete
> - The cleanup sweep retries such a lease only after a cooldown of up
to 5 minutes
> - A consented delete therefore returned 409 `pending_sandbox_cleanup`
for minutes. A caller with a shorter deadline gave up, and the
environment and its sandbox stayed behind
> - This pull request makes the consented delete run one teardown
attempt for the environment's pending cleanups now, then re-check
> - The benefit is that a consented environment delete completes as soon
as the provider teardown succeeds

## Linked Issues or Issue Description

**What happened?**
After a restart chaos wave, the harness deleted the wave's Daytona
environment with `destroyReusableSandboxLeases=true`. The server
returned 409 `pending_sandbox_cleanup` every 3 seconds for the whole
120-second client deadline. A run lease had entered `pending_cleanup`
after its run failed, and the sweep's retry cooldown had not passed. The
environment was not deleted.

**Expected behavior**
With explicit consent, the delete tears down the environment's own
pending sandbox cleanups and completes when that teardown succeeds. A
teardown that fails, or one already in flight elsewhere, still blocks
the delete.

**Steps to reproduce**
1. Leave a sandbox lease of an environment in `pending_cleanup` with a
future retry time.
2. `DELETE /api/environments/:id?destroyReusableSandboxLeases=true`.
3. On master, the response is 409 `pending_sandbox_cleanup` until the
cooldown ends.

Refs #19696 (restart recovery for creation and teardown claims; this
builds on it).

## What Changed

- `heartbeat/recovery.ts`: `sweepPendingCleanupLeases` accepts
`environmentRetry: { environmentId, actorId }`. Like the existing
run-scoped explicit retry, it bypasses the cooldown for one attempt,
never takes over an in-flight attempt, and logs
`environment_lease.cleanup_retried` with reason `environment_deleted`.
It touches only that environment's leases.
- `routes/environments.ts`: when the delete has consent and the only
blockers are pending cleanup and reusable leases, it runs that retry
first, then re-reads the blast radius. The existing reusable-lease
destroy and the final guard are unchanged. The new dependency is a
narrow, optional `retryPendingEnvironmentCleanup` option; without it,
behavior is unchanged.
- `app.ts`: wires the option to the existing heartbeat service instance.

## Verification

- Red, then green:
- `environment-routes.test.ts`: "runs the environment's pending sandbox
cleanup now and deletes with explicit consent" and "keeps rejecting when
the consented pending cleanup attempt does not finish" fail before and
pass after. "does not run pending sandbox cleanup without consent or
past another blocker" passes in both.
- `heartbeat-pending-cleanup-sweep.test.ts`: "runs one attempt for a
deleted environment's cleanup during its cooldown, scoped to that
environment" fails before and passes after. It checks that another
environment's lease and an in-flight claim are untouched, and that the
activity log is written.
- `sandbox-creation-operations.test.ts`: "reclaims an issue-bound
creation after its run failed and the issue finished on a later run"
covers another chaos finding. A creation intent bound to an issue was
interrupted by SIGKILL 0.5 s after it committed, its run ended
`process_lost`, and a later run finished the issue. The test fails on
the code before #19696 and passes on master, so #19696 already covers
this case. The test is kept as a regression.
- After rebasing on master, `environment-routes`,
`heartbeat-pending-cleanup-sweep`, `agent-runner-qualification-routes`
and `sandbox-creation-operations` pass (192 tests). `tsc --noEmit`
reports no errors in the changed files.

## Risks

- A consented delete now makes provider teardown calls for pending
cleanups. Those sandboxes were already queued for destruction, and the
operator consented to destroy the environment's sandboxes.
- One explicit attempt counts toward the lease's attempt cap, the same
as a user Retry.
- The delete request now waits for those teardown attempts. Each attempt
uses the existing plugin timeouts.

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).

18be7ac696 fix(server): retire idle native sessions before tenant sleep (#18988)
## Thinking Path

> - Paperclip lets people manage AI agents and their work.
> - Native agents can retain a warm session between useful turns.
> - That owner must close and save its files before the tenant can
sleep.
> - A failed close must keep the owner visible until retirement
succeeds.
> - This PR prepares idle resources under the exact current admission
hold, then takes a fresh safety snapshot.
> - Busy turns, uncertain closure and changed holds still prevent sleep.
> - CI also exposed a chat authorization race. The fix repeats full
authorization after the exact delivery commits.

## Linked Issues or Issue Description

Refs #18639 for local work and incoming wake boundaries. Related #18829
covers suspension receipts after admission.

**What happened?**

Idle preflight did not retire warm Native owners. Three failed-close
paths could forget an owner without proving that its provider stopped.
CI also found a false chat rejection when a delivery changed from
processing to processed between two validation reads.

**Expected behavior**

Retire only idle owners under the exact bounded hold. Wait for closure
and file collection. Retain failed owners. Scan safety after
preparation. Keep diagnostic reads passive. A newly committed chat
delivery must pass the full current authorization checks before
attestation succeeds.

**Steps to reproduce**

Finish a warm Native turn. Start an idle drain and request safety with
its owner ID. Delay or reject provider closure, or replace the hold
during preparation or scanning. The report must keep the instance awake.
For the chat race, commit the exact delivery between the first binding
read and its fallback read.

**Paperclip version or commit**

Current head `7f6f02b611dcf5a9a2b05173a44e9631eaf78058` normally
integrates actual master `1aa0c3639714f4976cfa56f95aae6e2b7d1235ac`. The
merge preserves every unrelated master path. Fresh exact-head CI and
complete review remain required.

## What Changed

- Retain uncertain Native owners after failed restart, idle timeout and
failed-turn closure.
- Prepare Native retirement through the existing heartbeat facade. Reuse
provider closure and stopped-file collection.
- Track preparation under the exact idle owner and expiry. Reject new
activity, changed holds and expired holds before and after awaited work.
- Take the final durable and local safety snapshot after preparation.
Keep diagnostic inspection passive.
- Cover ephemeral workspace retirement and useful next use, supported
plugin drain and SDK persistence, busy owners, failed closure and hold
replacement.
- Keep dedicated recovery storage explicit. Use the same validated
options for support and storage. Probe-free helpers retain the original
implementation bodies and preserve default callers.
- Complete the Native fixture through real retirement and budget
evaluation. Keep its rejection, file, credential, accounting and strict
NONE assertions.
- Repeat the complete chat authorization once if the fallback sees the
exact batch now processed. Preserve owner locks, principal and binding
checks, denial handling and the original retry deadline.

## Verification

- The support-mode regression reproduces one failure with four passes
under the old policy, then passes all five controls. It retains prior
allocation and cleanup cases. The explicit mode does not probe embedded
PostgreSQL or use an admin alias.
- The deterministic chat race baseline reproduces two authorized
failures with all four current-authority denial controls passing. Both
Slack and Discord use real PostgreSQL and the real authorization
function. The negative setup commits before the attestation transaction;
it does not claim to revoke access through a row lock.
- The product fix passes normal own App declaration emission with no
public declaration changes, plus both current normal owning compiler
programs (399 and 611 roots). The same six controls pass after the fix.
The full original file plus these controls passes all 30 tests with no
skips.
- The original controlled Native continuation passes: one test, no
failures or skips, 1.718 seconds in its body and 23.138 seconds in its
launcher. The original 40-second case and 180-second outer bounds are
unchanged. It verifies held closure, strict NONE, an ordinary authorized
comment, saved session/files, useful output, encrypted credentials,
accepted results and settled accounting. All ten observed processes and
groups close; worker connections and listeners reach zero. A separate
post-owner audit finds zero sessions; the successful owned database is
normally removed.
- Earlier preparation, HTTP, lifecycle, workspace and plugin controls
remain source-specific evidence. They are not a claim that every
final-tree test ran locally.
- The original CI assertion log is retained. The controlled race proves
a possible cause; the original CI SQL schedule was not captured. Two
other jobs lost their self-hosted runners and provided no test verdict.
Earlier asset timeouts, readiness failures and unexplained later
recovery remain separately recorded. No timeout, failure predicate or
authority check was weakened.

Focused public commands:

```sh
pnpm exec vitest run server/src/__tests__/idle-sleep-preparation.test.ts server/src/__tests__/instance-settings-routes.test.ts --maxWorkers=1 --no-file-parallelism
pnpm exec vitest run server/src/__tests__/heartbeat-reviewed-chat-binding.integration.test.ts --maxWorkers=1 --no-file-parallelism
```

Local database qualification uses fresh owned test databases on existing
PostgreSQL, bounded pools and one worker. The local allocation adapter
changes only database allocation for this test module; it runs normal
migrations and client cleanup. It is not part of the published source.
No new cluster is created.

Local acceptance measured the `0a69efa6` integration with the same
committed authorization bytes. The later normal master merge adds
startup-timeout classification and recovery changes. Those paths are
outside the controlled healthy-backend witness; retirement and
authorization hunks are preserved. Exact-head remote CI at
`7f6f02b611dcf5a9a2b05173a44e9631eaf78058` has completed with 56
successful contexts and four skips. The complete current Greptile
summary is5/5 with no new actionable findings; all review threads are
resolved. Ponytail’s current turn is explicitly paused without a
current-head verdict; earlier actual findings are fixed and accounted
for. No whole final-tree local repository build/test run, live-provider
restore or deployed suspension is claimed.

Actual master subsequently advanced to
`d5c4f7dd02d408a261cedd9a1926b9900a4aedc4`. Its local normal-merge
projection with this reviewed head preserves all20 owned paths and every
unrelated master blob and mode. Current Runner TypeScript, App
declarations and their full owning compiler programs pass. Focused
Native cleanup and warm-continuation composition checks are being
completed before merge; the new upstream suspension-retry behavior is
not inferred from the older controlled-backend witness. The remote PR
head remains unchanged.

## Risks

- Privileged idle preparation can close idle warm Native sessions. It
requires the exact current hold.
- Failed closure retains its owner and can keep the tenant awake until
normal retry succeeds.
- A changed hold cannot authorize sleep. Started cleanup remains tracked
until it settles.
- The chat repair can perform one extra full authorization read. It
keeps the existing deadline and does not grant authority from the
fallback query.
- Unsupported resources and active work retain their existing blockers.
This PR does not certify every transport, plugin or deployed host.

## Model Used

OpenAI `gpt-6.1-sol` produced the delegated changes and verification.
OpenAI Codex, based on GPT-6, performed managing review and integration.
Both used repository tools and code execution. The coordinator's exact
backend snapshot and context-window limits were not exposed.

work
> - Remote agent runs execute in provider sandboxes (for example
Daytona) that Paperclip creates and must clean up
> - Before each provider create, Paperclip saves a durable creation
intent (`sandbox_creation_operations`). Recovery uses it to find and

## Linked Issues or Issue Description

**What happened?**
A control-plane restart during Daytona sandbox acquire left the created
sandbox without an `environment_leases` row. In one restart chaos wave,
6 creation intents stayed `pending` with `next_attempt_at` = creation +
30 minutes. The wave ended (and its environment was deleted) before that
time, so 4 sandboxes stayed `stopped` in Daytona. Only Daytona's own
auto-delete would remove them. Two of the runs did not exist in
`heartbeat_runs` because they were non-run acquires; their intents still
had the run id.

**Expected behavior**
After a restart, each sandbox that this instance and company created,
with no committed lease and no live creator, is found by its exact
creation name and labels and destroyed through the plugin, after the
existing ownership checks. Sandboxes from another instance, another
host, or a live server stay untouched. Nothing acts org-wide.

**Steps to reproduce**
1. Start a Daytona-backed run.
2. Kill the server (SIGKILL) after the creation intent commits and
before the lease commits.
3. Restart the server. On master, the intent stays `pending` for 30
minutes and the sandbox stays in Daytona.
4. The regression tests in
`server/src/__tests__/sandbox-creation-operations.test.ts` reproduce
this with the controlled provider fixture.

Refs #18357 (added the durable creation intent this change completes).

**Paperclip version or commit**
master 07a548073a (live proof at 8d525dba7d + this change,
content-matched to the runner image)

## What Changed

- New `server/src/services/controller-process-identity.ts`: records the
server boot id, PID, a PID-space hash and the process start time. The
PID-space hash covers the hostname, the kernel boot id and the PID
namespace on Linux (the hostname and boot time elsewhere), so containers
that share a hostname but not a PID namespace never judge each other. It
proves that a recorded process exited only in the same PID space: the
PID is gone, or the PID is live with a definitely different start time.
Another PID space, an unreadable identity, an unidentified record, or
this server never counts as exited.
- `sandbox-creation-operations.ts`: each creation intent stores the
creating process and its settle deadline. Each recovery pass first moves
intents whose creator exited to "due now". If the early lookup finds no
sandbox before the settle deadline, the intent stays `pending` and
retries. It does not become manual reconciliation, because the provider
can still materialize an aborted request.
- `heartbeat/recovery.ts`: each pending-cleanup teardown claim stores
the claiming process, bound to its claim attempt id. Before the sweep
reads due leases, it ends the 15-minute fence of a claim whose claimer
exited. A newer claim from another path (workspace repair, export retry)
that kept an older record has a different attempt id, so it is never
released.
- Both recovery passes page through candidates with a stable id cursor.
Live, foreign or unidentified owners therefore cannot hide an abandoned
record behind one page.
- This covers every `createOwnedSandbox` caller, including non-task
probe and qualification acquires. Their intents have no issue and a
generated run id, which is why their run ids are missing from
`heartbeat_runs`.
- Recovery uses only the existing paths: exact
`paperclip-create-<operation id>` name and label inspection in the
plugin, `pending_cleanup` lease, and plugin teardown. No org-wide
listing or deletion was added.

## Verification

- Red, then green (controlled provider fixture, real embedded
PostgreSQL):
- `sandbox-creation-operations.test.ts` → "after the creating server
exits mid-acquire". Before the fix, the exited-creator case left no
cleanup lease. After the fix, the next sweep creates the
`pending_cleanup` lease and the teardown destroys the sandbox.
Counter-tests: a creation owned by this live server, another live
process, another host, or a committed lease is not inspected or
destroyed. An early "not found" keeps the intent pending, and a later
sweep still finds a late allocation.
- `heartbeat-pending-cleanup-sweep.test.ts` → "a teardown claim whose
server stopped mid-attempt". Before the fix, a lost claim blocked the
teardown. After the fix, it retries now. Counter-tests: claims from this
live server, another host, or without an identity keep their fence.
- Review regressions: "keeps the fence of a newer claim that kept an
earlier attempt's server record" and "pages past more fenced claims than
one sweep page" fail on the previous commit and pass now. "pages past
more unprovable creations than one page" guards the creation-side
cursor; the old unordered page happened to include the row, so it was
not red.
- After the review changes, `sandbox-creation-operations`,
`heartbeat-pending-cleanup-sweep`, `live-recovery-work` and
`environment-cleanup-work` pass (155 tests), and `tsc --noEmit` for
`server` passes.
- Related suites pass: sandbox-creation-operations (28),
environment-cleanup-work, task-creation-recovery,
native-startup-cleanup-recovery, sandbox-orphan-cleanup-spool,
plugin-warm-tasks, idle-completed-history (187 total), and the
pending-cleanup sweep suite. `tsc --noEmit` for `server` passes.
- Live Daytona restart chaos wave `w-20261107T001609-s11` (codex, A1,
K2+K4, concurrency 2, RC-06 masked, image `sha256:2767e91c…`, first fix
only): 4/4 tasks pass, all restart-crossing, R6 pass for every task,
`orphanSandboxes: []`. The server log and database show two creation
intents killed by K4 being reconciled right after restart and destroyed
through Paperclip. A third reclaimed sandbox lost its teardown claim to
the next K4 kill in the same second, so its 15-minute fence blocked the
environment delete. The second commit fixes that.
- Live Daytona wave `w-20261107T012048-s11`, same plan, both commits:
**4/4 pass, all restart-crossing, R6 pass for every task,
`orphanSandboxes: []`, no held leases.** The environment delete through
Paperclip succeeded with `remainingSandboxes: []`. One restart-time
sweep destroyed one sandbox through the plugin.

## Risks

- Same-host proof relies on PID liveness and process start time, as
native controller takeover already does. A false "exited" result is
limited to recovery running early. The plugin still checks exact name
and labels before any delete. An early not-found result stays pending.
- Multi-host deployments sharing one database keep the old deadlines,
because a different PID space is never judged. A redeploy into a new
host or PID namespace also keeps the old deadlines (fail closed).
- The live waves ran before the review commits. The review commits only
narrow when a record is judged, and they add paging.
- Intents and claims written before this change have no process
identity, so they keep the old deadlines.
- No schema change. The new fields live in existing JSON metadata.

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).

DottaandPaperclip d5c4f7dd02 fix: preserve shared Git sources during online workspace migration (#19688)
## Thinking Path

> - Paperclip preserves the work produced by its agents.
> - Remote workspace migration must preserve legacy Git history and
local edits.
> - Linked checkouts can share administration and objects with other
tasks.
> - A task lock alone cannot exclude writers of a shared or borrowed
store.
> - The online source owner must derive and retain the full physical
ownership closure.
> - This change reuses task, project, lifecycle and finalizer locks for
that closure.
> - Idle legacy Git work can then migrate while unrelated remote turns
continue.

## Linked Issues or Issue Description

Refs: #19642.

**What happened?**

Online migration keeps legacy Git sources blocked because several task
checkouts can share a project base or a private Git cache. A read-only
source observation found 160 pending Git records, 120 distinct paths and
nine common stores. Its largest project cohort contained 126 records and
110 task owners. An ordinary-directory fence cannot preserve these
sources by itself.

**Expected behavior**

Derive the physical source owners from stable Git metadata. Hold their
existing source and lifecycle keys through publication. Retain all
history and recovery obligations. Reject foreign aliases, unknown stores
and changed sources. Let unrelated object-backed work continue.

**Steps to reproduce**

1. Create a managed project checkout and linked task worktrees.
2. Keep a settled prepared recovery source on a sibling task.
3. Keep unrelated remote work running.
4. Request an online import of an idle leaf checkout.
5. The existing owner keeps the shared source blocked.

**Paperclip version or commit**

This branch builds on merged #19642 (`7ac99718a4`) and fresh master
`fb3cf1a072`. It adds the Git closure. It does not add a writers-stopped
shortcut.

**Deployment mode**

Hosted native Runner with remote workspace storage. Local qualification
uses owned synthetic Git repositories, disposable PostgreSQL databases
and the actual archive and storage owners.

## What Changed

- Read bounded stable Git pointers, common-directory metadata and local
alternates. Derive the complete physical source ownership cohort.
Preserve all object stores.
- Retain common and borrowed store owners in preparation, lifecycle,
runtime, expiration and actual reopen paths. Keep company boundaries and
the existing 128-key bound.
- Hold exact sibling native recovery proofs under their existing
physical finalizer keys. Recheck descriptors, allocations, recovery
actions and source identities before capture and publication. Preserve
original states and warnings.
- Require leaf-first nested imports. Reuse the existing immutable child
download, restore and source comparison before parent exclusion.
- Bind the self-contained archive owner to the held Git namespaces. Keep
its three walks, history normalization, fsck, bytes and digest format.
Reject bare, detached, network, unknown or changed Git storage.
- Check both foreign path fields. Keep foreign metadata private.
Document the proof, bounds, source observation and remaining eligibility
limits.

## Verification

- Final revision `2934e41c923b93e16508b978c849b747c86be645`: all checks
are terminal, with 56 successful and four skipped, zero failures and
zero pending. The [required CI
aggregate](https://github.com/paperclipai/paperclip/actions/runs/42326464408/job/128266279210)
passed. Build, types, all server/Runner/serialized suites, end-to-end
aggregate and Snyk passed. [Fresh exact-head Greptile
review](https://github.com/paperclipai/paperclip/pull/19688#issuecomment-6699760104)
is 5/5 with no open threads. GitHub reports MERGEABLE and CLEAN.

- Review then found two correctness gaps: an ordinary managed directory
inside an unrelated host repository was blocked, and a Git parent could
miss a completed nested operation after its child snapshot became
missing or deleted. Three actual-owner regressions reproduced both gaps
in 9.70 seconds. The corrected owner passes 12 focused cases in 17.08
seconds. It imports and restores only the ordinary root bytes, preserves
the outer repository, rejects both missing/deleted child receipts before
a parent journal, and retains valid/changed child coverage and
private-cache contention. Its wrapper exited 0 and cleanup completed.
The first bootstrap attempt failed before tests ran because the host
exhausted its 32 shared-memory segment limit; no shared services were
stopped and no pass is claimed for that attempt. The final qualified
source/test type graph, module boundaries and diff checks pass.
- Receipt scans keep canonical path resolution. A lexical SQL prefix can
omit children reached through symlinked ancestors. The observed full
metadata closure completed in 1.17 seconds; no measured bottleneck
justifies weakening that alias proof. Writer admission still rejects
uncertain Git ownership before mutation. Expiration returns its typed
skip, and reopen returns its structured failure. Runtime and lifecycle
do not bypass an unknown source. No broad error-contract change was
added.

- Full CI at `720104ea975e` exposed five existing boundary cases across
three server shards. Four exact cases reproduced locally as failures in
25.98 seconds. Reopen now preserves its structured failure when source
inspection rejects the path, without reconstructing it. Runtime
recognizes only the exact regular ignore-only `.git/info/exclude`
fragment; migration still rejects that fragment. The original
arbitrary-path and file-URL import/delete-host/resume fixtures keep both
supported input forms and use the genuine offline setup path after their
sole writer finishes. The production mode gate is unchanged. A new
real-owner control proves the offline flag still rejects a running
legacy database writer.
- The final focused run passed all ten cases across four suites in 22.75
seconds, including all five CI failures, invalid-pointer admission,
fragment rejection, offline writer exclusion and actual nested reopen
lock ordering. Its wrapper exited 0 and cleanup completed. The known
invalid-pointer case remains fail-closed; the separate unexpected-I/O
diagnostic retains safe error metadata without command text or
credentials. Existing Git stderr redaction coverage remains intact. The
final metadata reader suite passed 20 cases in 2.68 seconds. The
qualified server/test source type graph, module boundaries and diff
checks pass. No production assertions or timeout defaults were weakened.
Fresh CI and review are required for the repair revision.

- A later review found that the ordinary early return still used only
one foreign path field. The actual ordinary providerRef-only regression
failed as incorrectly eligible. One source-path owner now enumerates
both local locators for company/foreign ordinary and Git scans, layout
checks, early admission, lifecycle/reopen/runtime and
expiration/move/preparation retention. Capture and display keep their
original preferred path. The actual owner canary passed 49 cases across
two suites in 109.15 seconds. It covers
cwd-only/ref-only/different/symlink locators, same-company mismatches,
foreign owners, lifecycle ordering, Git/recovery imports and
expiration/reopen. Three selected-locator fallback cases also failed
before their guard; the final eight-case control passed in 31.05
seconds, including the configured alias and valid import/private-child
controls. All wrappers exited 0 and completed cleanup. The
metadata/locator suite passed 19 cases. The final source/test type
graph, module boundaries and diff checks pass.

- Review found two P1 gaps. Both configured-directory symlink cases
failed before canonicalization. The actual parent import lost an
already-imported child's unique private cache and failed its archive
fence instead of retaining that owner. The corrected real-owner canary
passed four cases in 20.78 seconds: configured symlink runtime
provisioning, private-cache contention before the parent journal,
successful parent publication after release, and unchanged/changed child
coverage. The metadata suite passed 15 cases in 4.14 seconds. Both
wrappers exited 0 and cleanup completed.
- A fresh source read-only observation found 160 pending Git records and
nine common stores. An additional exact receipt query found 1,243
completed migration receipts and 557 nested source paths under pending
Git roots. All 126 records in the largest project were present in the
captured Git metadata set. For all 110 present candidate workspace
records, the derived closure fits the unchanged 128-key cap. The worst
case needs 110 issue keys and one project key, with 17 keys of headroom.
Its 173 imported children introduce no physical issue owner outside
those 110 logical task owners. This checks the observed key bound only.
It does not claim migration eligibility or a coherent snapshot.
- The initial stacked CI did not run four Runner test lanes: trusted
master passed new --package-lane/--native-server options to the old base
lane script. The branch is now rebased onto actual merged master and
retargeted before synchronization. It includes the canonical current
lane parser without an unrelated Runner patch. Fresh new-head CI is
required.

- The actual importer/source owner run passed 36 cases across three
suites in 187.75 seconds. It covers sibling prepared recovery, unrelated
running remote work, common-cache contention, changed
coordinator/allocation/path state during upload, exact nested coverage,
dirty unpushed work, and existing expiration/reopen owners. Wrapper exit
0 and cleanup completed.
- A separate previously hanging lifecycle-worker restore passed in 17.33
seconds with the unchanged 15-second test-body limit. An earlier run
timed out in three expiration/reopen cases and blocked cleanup; its
wrapper later exited 1. These failures remain recorded. They are not
counted as passes.
- Two boundary controls first failed: a foreign providerRef-only alias
was incorrectly eligible, and actual reopen did not admit its distinct
cache owner at the initial source boundary. The narrow guards now
inspect both foreign locators and derive physical Git keys before the
raw lifecycle transaction. The foreign alias and existing real nested
reopen contention passed. The private-cache control first retained
contradictory recorded source provenance and stayed fail-closed after
release. The corrected present legacy-worktree fixture passed in 12.61
seconds. These failed attempts remain recorded; they are not passes.
- The metadata reader and serialized/local archive controls use actual
Git repositories. They compare archive bytes and digests, remove every
original source, restore staged and unstaged work, and run fsck. The
metadata reader passed 13 cases in 2.85 seconds. The local/serialized
archive controls passed nine cases in 9.27 seconds. All processes exited
0. An additional actual importer control changed a relative commondir
pointer to the absolute name of the same store during upload.
Publication was rejected, the uploaded journal remained available, and
original files stayed intact (one case, 5.86 seconds; wrapper exit 0 and
cleanup complete).
- The final rebased full local server/test type graph passes with
db/shared/Runner source aliases because reused dependency declarations
predate new master exports. The first rebased attempt reported those
stale declaration fields/tables, and is not counted as a pass. Module
boundaries and diff checks pass. Standard package builds, types and
broad regression checks remain required in CI.
- No hosted import, admission hold, cancellation, provider mutation,
source filesystem write or shared-cache Git command was performed for
this change. The source observation is read-only and is not a locked
eligibility proof.

## Risks

- A missing writer owner could make physical source exclusion
incomplete. Existing mutation owners retain the same
company/task/project keys, and uncertain metadata fails closed.
- A project can contain a large cohort. Limits remain finite. A bound
failure keeps the source blocked.
- Bare, detached, unowned or network Git stores remain blocked online.
Missing archived sources retain their existing authenticated
reconstruction path.
- Exact recovery proofs preserve authority and obligations. They do not
infer provider termination or mark a prepared descriptor finalized.
- This change does not claim all observed Git records are immediately
eligible. Existing preparation, provider, recovery, runtime and
source-change blockers remain.

## Model Used

OpenAI GPT-6 through Codex, with reasoning, tool use and code execution.
The host does not expose a more specific backend model ID or
context-window size.

DottaandPaperclip 5e4d24b6c8 fix(recovery): preserve admitted workspace on native restart (#19693)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - A Retry can admit a new workspace before native provider work
starts.
> - The native execution input records that admitted workspace.
> - A server restart must recover the same run under that recorded
contract.
> - Retry readiness previously evaluated fresh admission again after the
run had started.
> - This could replace the workspace and make the retained lease fail
its correct identity checks.
> - This change keeps the admitted workspace and leaves reattachment
authority with the existing lease and controller checks.

## Linked Issues or Issue Description

**What happened?**

A native run started by Retry could do useful work, then fail after a
server restart. Preparation evaluated the original fresh-workspace
receipt again. It reserved a replacement workspace under the Retry
intent ID. The existing runner still owned the original workspace, so
setup failed with `native_remote_recovery_lease_mismatch`.

**Expected behavior**

Restart recovery must retain the workspace recorded in the same run's
native execution input. A later configuration or admission decision must
not replace it.

**Steps to reproduce**

1. Admit a remote workspace for a Retry run.
2. Persist its native execution input and keep its original controller
and environment lease records.
3. Recover the same run while its canonical Retry receipt selects fresh
admission.
4. Preparation must reach the original lease with the original
workspace.

Related: #19340 preserves verified Retry workspaces. This change handles
an already admitted native run instead of selecting a workspace for a
new turn. Public duplicate searches for admitted/fresh workspace restart
found no matching repair.

## What Changed

- Stop fresh admission when a parsed native input names a real workspace
in the run's company.
- Validate the company, run, agent, and task binding before using that
input.
- Keep synthetic run-ID bootstraps on the existing admission path. Hold
missing real bindings.
- Test both recovery-action and ordinary user-Retry receipts against
real workspace, controller, and lease rows. Check malformed, foreign,
missing and opaque bindings, synthetic bootstrap behavior, and no-files
API controllers.
- Align the resume-owner fixture with the real transient run-ID binding.
Give each invocation a unique issue label so a CI test retry cannot mask
the original failure.

## Verification

- RED on unchanged production: the new reservation regression failed
with `native_remote_recovery_lease_mismatch` instead of reaching the
admitted lease.
- Review RED: an opaque task-workspace ID reached the UUID query. The
new guard returns the controlled missing-admission error before the
query.
- Review RED: a valid no-files Cursor controller was treated as a
missing task workspace. The existing task-workspace projection now keeps
that controller on its prior path.
- Clean final production-source regression: both restart cases passed in
a fresh embedded PostgreSQL cluster. These cover both receipt paths and
all binding, bootstrap and API-controller controls.
- The initial focused checks passed 11 cases. Seven existing ordinary
Retry and environment selection cases also passed. A later combined
final-base run had 17 assertions pass but failed workspace teardown at
90 seconds and task-Retry setup at 30 seconds. That attempt is retained
as a failure; the two new restart cases then passed alone with exit 0.
Earlier PostgreSQL support-probe failures are also retained as setup
failures.
- The worktree's own Runner, shared and SDK dependencies were built. All
seven server typecheck layers passed for the final production source.
The final additional commit changes only the existing resume-owner
fixture.
- Required CI found an invalid fixture binding in [server shard
11](https://github.com/paperclipai/paperclip/actions/runs/42322379917/job/128250151095).
The first attempt failed before lease acquisition because the fixture
named a random workspace with no row. The automatic test retry then
failed on its fixed issue label. The fixture now uses the transient
run-ID contract and a unique label. Its exact original acquisition and
owner-release assertions pass locally with exit 0.
- Whitespace and added-code-comment checks passed.
- Final commit `f0e41e8c6b949f43863ec60fc7b96b97025eafc6` passed
required
[CI](https://github.com/paperclipai/paperclip/actions/runs/42323826555):
56 successful checks, four intended skips, one neutral result, and no
pending or failed checks. Greptile and Ponytail both gave this exact
head 5/5 with no actionable findings. No review threads remain open.
Hosted deployment and original-task recovery remain separate from local
proof.

## Risks

Malformed or missing native admission records now hold rather than
selecting fresh work. Valid initial admissions and synthetic run-ID
bootstraps retain their prior path. The change does not grant
reattachment authority or settle provider effects. Existing controller,
workspace writer, lease, Stop, and trust checks still apply. No API,
schema, or configuration contract changes.

## Model Used

OpenAI GPT-6 family through Codex. The runtime does not expose the exact
serving model ID or context window. No model override was used. The
assistant used reasoning, code editing, shell tools, and local tests.
