DottaandClaude Opus 5.5 686893636d fix(recovery): release a lapsed owner of a finished coordinator so stop-proof holds re-arm (#20661)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Workspace recovery saves the files of a run whose copy-back failed,
and it holds the shared workspace until the save is done
> - #20295 re-arms a save that was exhausted with
`agent_stop_unconfirmed`, so the run's stop is proven again and the
files are saved without a person
> - On staging, four holds of this shape were never re-armed. Their runs
ended six days ago, their sandbox leases are released with a provider
stop receipt, and the servers that ran them were replaced many times.
Their tasks stay blocked, and so do the parent tasks that wait for them
> - The finished coordinator of each run still names a lease owner whose
lease lapsed. Discovery treats that owner as "waiting for the
abandoned-owner settlement", but that settlement handles only observed
(unfinished) coordinators. Nothing ever releases the owner, so the
worker never selects the hold, the re-arm refuses it, and the attempt's
stop check refuses it too
> - This pull request makes a lapsed owner of a finished coordinator
count as stopped. The re-arm releases it in the same transaction, and
then the new attempt proves the sandbox stop and saves the files as
#20295 designed
> - The benefit is that these holds settle on the worker's next pass
after deploy, without a migration and without an administrator

Refs #20295

**What happened?**
An exhausted workspace save
(`native_workspace_sync_out_retry_exhausted`, last failure
`agent_stop_unconfirmed`) stayed blocked for six days. The task showed
"Paperclip tries again automatically", but no re-arm was ever recorded
(no `stopProofRecovery` marker, no `issue.workspace_recovery_rearmed`
activity), and the shared workspace stayed held by the failed run.

**What did you expect to happen?**
The recovery worker re-arms the save once the run is provably over,
saves the dirty files, and frees the workspace so the task and its
parent can continue.

**Steps to reproduce**
1. Exhaust a workspace save with `agent_stop_unconfirmed` (one attempt,
window spent).
2. Leave a lease owner on the run's `terminal_failure` coordinator with
an expired lease (or no expiry), as a finalizer pass of a replaced
server does.
3. Run the workspace recovery worker. `nextWorkspaceRecoveryAt` returns
null, discovery does not select the hold, and `rearmExhaustedStopProof`
refuses it.

## What Changed

- `workspace-recovery-stop-proof.ts`: add
`lapsedFinishedCoordinatorOwner` and `releaseLapsedCoordinatorOwner`. A
lease owner on a finished coordinator (committed, terminal failure,
applied) whose lease lapsed, or that has no expiry, does not block
`sourceRunProvablyOver`. The stop-proof re-arm clears that owner with a
compare-and-swap in its locked transaction, and records
`releasedLapsedOwner` in the marker and the activity.
- `workspace-recovery-capture-policy.ts`: the capture-policy re-arm uses
the same rule, because it shares the same check and discovery clause.
- `workspace-recovery-fallback-discovery.ts`: the discovery clause still
waits for the abandoned-owner settlement for a stale owner of an
unfinished coordinator, but it no longer excludes a hold whose finished
coordinator has a lapsed owner. A live lease still defers the re-arm to
its expiry.
- `system-recovery-state.ts`: add `FINISHED_COORDINATOR_PHASES`.
- `doc/execution-semantics.md`: document the rule.
- Tests: two red-then-green regressions in the staging shape (an expired
finalizer lease, and an owner without an expiry saved by an older
release), one strictness case (a live lease on a finished coordinator
keeps the hold and is not released), and the existing stale-owner case
now uses an observed coordinator, which still waits for the
abandoned-owner settlement.

## Verification

- Red before the fix: `pnpm --filter @paperclipai/server exec vitest run
src/services/workspace-recovery-stop-proof.test.ts` failed the two new
staging-shape cases (`nextWorkspaceRecoveryAt` returned null: the worker
was never woken for the hold).
- Green after the fix: `workspace-recovery-stop-proof.test.ts` and
`workspace-recovery-capture-policy.test.ts` pass (15 tests). The
staging-shape cases assert that the hold is re-armed, the save
completes, the dirty files are saved, the workspace hold is free, and
the lapsed owner is released.
- `pnpm verify`: exit 2 (broader verification required, because
`doc/execution-semantics.md` is a global CI input). Focused suites pass:
`workspace-recovery-stop-proof`, `workspace-recovery-capture-policy`,
`workspace-recovery-fallback`, `workspace-recovery-retry-copyback` (113
tests). Required CI supplies the broad coverage.
- Staging evidence (read-only GET requests): the run is `failed`,
finished six days ago, `controllerLeaseExpiresAt` is null, its only
lease is `released` with `cleanupStatus: success`, a `stopped`
termination receipt and a stop-and-retain receipt. The action's evidence
has no re-arm marker, and four holds of the same shape were not touched
after #20295 was deployed.

## Risks

- Previous-release story: rows saved by earlier releases carry the
lapsed owner and no marker. They are selected and re-armed on the
worker's first pass after deploy. No migration.
- Strictness stays where an owner could be live: a live lease on any
coordinator defers the re-arm to its expiry, and a stale owner of an
unfinished (observed) coordinator still waits for the abandoned-owner
settlement, which proves its controller stopped. The new attempt still
requires a provider stop receipt for the allocation before it reads
files.
- Clearing a lapsed owner matches the existing token-lease contract: an
expired finalizer or cleanup lease is free for the next claim, and a
holder's later write fails its token compare-and-swap.
- Low risk otherwise: the change is limited to the two exhausted-hold
re-arms and their discovery clause.

DottaandClaude Opus 5.5 4f33bb3578 fix(workspaces): release the Blocked status of a sibling-settled no-replay hold (#20648)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When a remote workspace save fails, recovery actions hold the task
until the run's files are saved
> - #20641 lets a resolved no-replay hold settle when a sibling action
of the same run saved the files
> - Review found that the settlement did not release the task's Blocked
status, and that a settled hold with a historical source stayed
selectable
> - A new test with the waiting user comment also showed that the worker
skipped the second hold of the same run in every pass, so it never
settled
> - #20641 was merged before these fixes were pushed
> - This pull request completes #20641 with those fixes
> - The benefit is that the task leaves Blocked and continues without a
person

## Linked Issues or Issue Description

Refs #20641, Refs #20569

**What happened?**
#20641 merged at its first head. The review follow-ups for it were
pushed later and are not on master:
- A settled no-replay hold that owned the task's Blocked status
(`nativeFailureBlock`) left the task `blocked`.
- A hold settled by a sibling stayed selectable through
`workspaceRecoverySourceEligible` when it named a
`historicalWorkspaceSource`.
- With saved user input waiting, the export hold stayed selectable and
came first in each worker pass. `reconcileRetainedWorkspaces` skipped
the other hold of the same run, so the no-replay hold never settled.

**Expected behavior**
After the save, the no-replay hold settles in the same or next pass. The
task returns to `todo` when that hold owns its Blocked status. The
settled hold is never selected again.

**Steps to reproduce**
1. Use the staging-shape test in
`workspace-recovery-capture-policy.test.ts`, with a waiting "try again"
comment.
2. Run the worker until nothing is due.
3. On master, the worker never goes idle and the no-replay hold stays
`resolved`/`blocked`.

## What Changed

- `workspace-recovery-fallback.ts`: new shared `holdOwnsBlockedStatus`,
used by `continueFromLastSavedWorkspace` and
`settleSiblingRecoveredHold`. A settled no-replay hold that owns the
Blocked status returns the task to `todo`. A newer decision's Blocked
status is kept. An export hold's status stays with its own result
finalization.
- `workspace-recovery-source.ts`: `workspaceRecoverySourceEligible`
excludes a resolved hold that carries `siblingWorkspaceRecovery`.
- `workspace-recovery.ts`: `reconcileRetainedWorkspaces` runs several
holds of one run one after another in that run's job, instead of
skipping the later ones.
- `workspace-recovery-capture-policy.test.ts`: the staging test now has
the waiting comment, and a variant with `nativeFailureBlock` and
`historicalWorkspaceSource`. It checks `todo`, no re-selection, and no
repeat handoff in a later pass.
- `doc/execution-semantics.md`: documents these rules.

## Verification

- Red, with each rule disabled: the status stayed `blocked`; the settled
hold was selected again; the worker never went idle (starvation).
- Green: `npx vitest run --root server` on 14 workspace recovery suites
(including `workspace-recovery-capture-policy`, `-fallback`,
`-admission`, `-source`, `execution-blocker-read`,
`preserved-native-response-wait.integration`): all passed.
- `npx tsc --noEmit -p server/tsconfig.json`: clean.

## Risks

- Several holds of one run now run in sequence in one job. Concurrency
per run is unchanged (one job per run).
- A no-replay hold releases the Blocked status only when it still owns
it. Otherwise the status is kept.
- Previous-release story: no new persisted state. Holds saved by earlier
releases are handled on the first worker pass after deploy.

DottaandClaude 805531cc71 fix(native): never leave a cleanup-gated task without Retry or an owner (#20639)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs close their provider session at the end of each attempt.
When close cannot prove that the runner stopped, the runner keeps a
cleanup gate (`native_session_cleanup_quarantined`) in server memory
> - #20572 hid Retry for every gated run and said "Paperclip finishes
the cleanup automatically". Only a remote environment release settles
the gate. A local gate that needs an operator never settles, and a
server restart loses it
> - A restart-chaos wave on master found two tasks that rested blocked
with no Retry, no scheduled retry and no recovery owner. A person could
not continue them
> - This pull request makes the run's own recovery retire the gate when
the host proves the old processes stopped. It also offers Retry whenever
nothing settles the gate, and it makes that Retry work
> - The benefit is that a cleanup-gated task either continues by itself
or shows a Retry that starts. It never rests without both

## Linked Issues or Issue Description

Refs #20572, #20578

**What happened?**
Restart-chaos wave `w-20261110T185144-s9107` (local, claude, fault TM2:
the server is paused with SIGSTOP for about 33 s). Tasks t04 and t05
completed their provider turn. The runner checkpoint owner lapsed while
the server was paused (`native_runner_checkpoint_owner_lost`). The
session close then failed with `native_session_close_unrecoverable:
runner did not durably suspend before checkpoint`. The provider had
drained and no tool call was pending. The runner kept an
operator-required cleanup gate. Thirty seconds later the run's own
same-run recovery verified that the runner process and group had stopped
(`native.local_process_stopped`). The gate still refused the recovery,
and the run ended `failed` with `native_session_cleanup_quarantined`.
The task showed `canRetry: false` and a cleanup wait until the deadline.
Nothing owned that wait.

**Expected behavior**
When the old runner and provider processes are proven stopped, the run's
own recovery continues. When nothing settles the gate, the task offers a
Retry that starts.

**Steps to reproduce**
1. Run restart-chaos L7: `--env local --adapters codex,claude
--workloads A1,B5,C1 --faults TM1,TM2,TM3 --time-age-hours 1
--concurrency 3 --tasks 6 --seed 9107`.
2. Observe a claude TM2 task rest `blocked` with `canRetry=false`,
`retryWait=true` and no scheduled retry.

**Paperclip version or commit**
master at ed3ffc3bc7.

## What Changed

- `native-session-executor.ts`: add `provenStoppedOwnNativeSession`. It
returns proof only for a local run with a pid-bound
`native.local_process_stopped` record (no later launch) and with every
recorded provider process gone. An ACPX session open names no provider
PID; its sidecar counts only when it shares the runner's process group,
which the stop record proves empty.
- `native-session-executor.ts`: add
`retireStoppedOwnSessionCleanupGate`. With that proof, it retires the
run's own operator-required gate through the existing
`completeTerminatedLocalNativeSessionCleanup` boundary and records
`native.session_cleanup_gate_retired`.
- `heartbeat.ts`: the native recovery preamble calls it right after it
records the local process stop, before admission. The recovery decision
itself does not change.
- `explicit-native-continuation.ts`: Retry or a new message accepts the
run's own stop proof when the retained-state inventory proof does not
apply. It still starts a fresh session, and it never resumes the old
turn.
- `task-interruption-presentation.ts`: hide Retry for a gated run only
while a live owner settles the gate: an unreleased remote environment,
or a scheduled close in this process. Otherwise offer Retry. The same
rule applies to a Retry held on `cleanup_quarantined`.
- `doc/execution-semantics.md`: describe the new rule.

## Verification

- Red before the fix, green after (5 tests failed on master sources):
- `server/src/services/task-interruption-presentation.test.ts`: "offers
Retry when nothing settles the gate by itself", "holds a Retry on a
cleanup gate only while an owner settles it", and an invariant test: a
failed presentation without Retry must name a wait, and a cleanup wait
needs a settling owner.
- `server/src/__tests__/task-interruption-query.test.ts` (real
Postgres): an unreleased remote lease hides Retry; the released lease
offers it.
- `server/src/services/quarantined-task-retry.test.ts`: "starts a task
Retry for a run's own quarantine proven stopped by its own process
record" (stopped, and provider alive stays held).
- New: "retires a run's own failed-close gate once its runner and
providers are proven stopped" for codex PIDs, an ACPX sidecar in the
runner's group, a sidecar with its own group, a live provider, and no
stop record.
- `npx vitest run` of `quarantined-task-retry`,
`task-interruption-presentation`, `task-interruption-query` and
`explicit-native-continuation`: 575 passed.
- `npx tsc --noEmit -p server` passes.
- Live: LIVE_PROOF_PLACEHOLDER

## Risks

- The gate retirement removes process ownership only. It runs only for a
local run whose exact runner and group and every recorded provider
process are proven gone. A provider without a recorded process identity
keeps the gate.
- Retry on a gated run still runs every existing stop check. If the stop
cannot be proven, the Retry waits and the task keeps a Retry, instead of
a wait that nobody settles.
- No persisted shape changes. Runs saved by earlier releases use the
same fields.

DottaandClaude 37c50f70c2 fix(native): continue a turn lost on restore in a proven same-run resume (#20645)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native run keeps its provider conversation when its local runner
dies. When the restored runner finds that the active turn was lost, it
reports `provider_turn_lost_on_restore` and does not invent a result.
> - After a control-plane restart, the admitted restart attempt may send
one continuation in that same conversation (#15297). The agent then
reconciles unfinished work. The task is not resent.
> - A runner can also be lost without a server restart, for example when
`runner.drain` times out. The run then resumes itself after the retry
delay from its exact checkpoint. That path never allowed the
continuation, because the executor passed `resumeInterruptedTurn` only
for a `resume_dead_runner` restart claim.
> - So the lost turn failed with `native_provider_terminal_failed`,
automatic replacement was refused (`uncertain_provider_action`), and the
user had to click Retry.
> - This pull request allows the same single continuation for that
resume, but only when durable records prove the same three facts that a
restart claim proves.
> - The benefit is that a runner lost mid-turn continues in the same
conversation with no Retry. No case that is refused today becomes
allowed without that proof.

## Linked Issues or Issue Description

Refs #15297, #20625

**What happened?**
Restart-chaos wave L7 (seed 9107, local), task codex B5 TM2, run on
master after #20625. A TM3 restart resumed the run (attempt 1). During
the TM2 freeze the TS runtime lost its runner:
`native_session_recovery_failed: runner_local_connect_failed: PRP
command runner.drain timed out`. The executor saved `retryable_failure`
with `recoveryMode: "exact_checkpoint_resume"`. After the delay,
recovery verified the runner process stopped
(`native.local_process_stopped`). The same run then resumed as attempt 2
(`native.process_start_requested`, `providerAttempt: 2`). The restored
runner reported `turn.failed` with `provider_turn_lost_on_restore`
(`recoverable: true`). No continuation was sent. The run failed with
`native_provider_terminal_failed`, recovery stopped with
`uncertain_provider_action` / `preserve_without_replay_v1`, and the task
needed Retry.

**Expected behavior**
The run sends the one same-conversation continuation, exactly as it does
after a restart claim, and finishes without Retry.

**Steps to reproduce**
`node cli/node_modules/tsx/dist/cli.mjs tests/restart-chaos/main.ts
--env local --adapters codex,claude --workloads A1,B5,C1 --faults
TM1,TM2,TM3 --time-age-hours 1 --concurrency 3 --tasks 6 --seed 9107`
(timing-dependent: the drain timeout must land during an active turn).

## What Changed

- New
`server/src/services/native-runtime/scheduled-resume-continuation.ts`.
It decides whether a same-run scheduled resume may continue a lost turn.
Each of the three proofs comes from a durable record:
1. **The previous runner is stopped.** The latest process record of the
run in `heartbeat_run_events` (`native.process_start_requested`,
`native.process_identity_recorded`, `native.local_process_stopped`) must
be `native.local_process_stopped`. Its `processPid` must equal its
`processGroupId`, and neither the pid nor the group may be alive now.
This is the existing `readNativeLocalProcessStop` check, read in the
claim transaction before this attempt records its own
`native.process_start_requested`.
2. **The attempt was admitted under the bounded budget.** The executor's
claim moves `native_run_finalizations` from phase `retryable_failure` to
`observed`. It charges a provider attempt, and the claim refuses any
attempt above 3 (`native_session_retry_exhausted`). The decision also
requires `1 <= attempt <= NATIVE_PROVIDER_RECOVERY_ATTEMPT_LIMIT`.
3. **It is the same provider conversation.** The saved `failure_detail`
must show `recoveryMode: "exact_checkpoint_resume"`, `recoverable:
true`, `providerSessionEstablished: true` and `checkpointExists: true`,
with no `successorRunId` or `replacementDenied`. At run time the
existing runtime guards still apply: the backend must recover the
checkpointed session (`recovered`, not a continuity-break replacement),
and the lost turn must equal the checkpoint's `activeTurnId` and the
snapshot's interrupted turn. The provider kinds stay codex, acpx and
opencode, with no compaction, goal control, held result or pending
runtime request.
- `native-session-executor.ts`: computes that decision in the
coordinator claim. It passes `resumeInterruptedTurn` when either the
restart claim is `resume_dead_runner` (unchanged) or the decision allows
it.
- `doc/execution-semantics.md`: describes the rule and the refused
cases.

**Cases that stay refused** (each has a test in
`scheduled-resume-continuation.test.ts`):
- a restart-recovery claim (it keeps its own existing rule);
- a remote execution target;
- a coordinator that is not `retryable_failure`, including a fresh run;
- `recoveryMode` `bootstrap_retry` or `ambiguous_state`, or no saved
failure detail;
- a failure that is not recoverable;
- no established provider session;
- no checkpoint;
- a recorded replacement (`successorRunId` or `replacementDenied`);
- an attempt outside 1..3;
- no stop receipt, a stop receipt superseded by a newer launch, a
stopped process that is still alive, or a run that never had a process.

The runtime-side refusals are unchanged and already covered by
`native-session-runtime.test.ts`: real provider errors, historical
error-null failures, and no restart permission.

## Verification

- `cd server && npx vitest run
src/services/native-runtime/scheduled-resume-continuation.test.ts`: 22
tests, covering the decision table and the stop receipt in embedded
Postgres.
- `cd server && npx tsc --noEmit` passes.
- Live: not proven. An L7 wave on this branch (seed 9107) did not
reproduce the drain-timeout path, so this pull request has unit and
database tests only. In that wave the same cell (codex B5 TM2) needed
Retry for a different reason: TM2 aged its restart-recovery claim lease
before dispatch, and budget admission refused with `Native recovery no
longer owns provider dispatch`. This pull request does not change that
path. Four other tasks passed. Claude C1 TM2 rested blocked without a
Retry button, which is a separate cleanup-quarantine issue.

## Risks

- This allows one more path to send the same-conversation continuation.
It is limited to local runs. It needs the same proofs as a restart
claim, and it uses the attempt the resume already charged. It does not
change the generation cap or `restartResumeKeepsAttempt`.
- A rolling deploy reads `failure_detail` and stop events written by
earlier releases. Those fields and events already have this shape, so an
older saved failure is judged by the same rule.

## Model Used

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

## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work

## Linked Issues or Issue Description

Refs #20572 (that PR fixed the presentation of this quarantine. Its
Risks section names this runner drain rule as a separate follow-up.)
Refs #20641 (it settles a resolved no-replay hold when a sibling action
saved the run's files. This PR covers a different case: the hold's own
recovery saved the files, and its run's turn completed. Both use the
same recovery receipt, `completedWorkspaceRecoveryCondition`.)

**What happened?**
A remote native run started an assigned app tool call. The server
restarted 3 seconds later. The new server adopted the runner, and the
provider turn completed about 9 minutes later. The tool call never got a
saved result. Close reported `native_session_settlement_incomplete` with
`runnerSuspended: true`, `providerDrained: false` and one pending
callback. The session quarantined, and the same-run recovery was refused
at admission. A second run showed the same shape with a
`connections_search` callback after a later restart.

The first run then had two resolved-but-blocked holds with
`preserve_without_replay_v1` and an unknown action outcome: the
cleanup-quarantine hold, and a continuation hold whose workspace
recovery saved the files. The task view said "Saved work recovered. Send
a message to continue." with no Retry and no continuation. The task
waits on a child task and stays blocked.

**Expected behavior**
After a restart, a tool call without a saved result settles
automatically. A durable receipt is replayed. Without a receipt, the
agent is told that the outcome is unknown. Close proves the drain, and
no cleanup gate is left. Holds that earlier releases left for a
completed turn settle without a person, and the task continues when its
own wait ends.

**Steps to reproduce**
1. Start a native run and call an assigned app tool.
2. Restart the server while the tool call runs.
3. Let the adopted turn complete, then close the session. Close reports
`native_session_settlement_incomplete` and quarantines. The task stays
blocked by the no-replay holds.

**Paperclip version or commit**
master at fd6e71a7ff.

## What Changed

- Root cause: `DurablePrpControlPlane.#recoverPendingSemanticInputsOnce`
(`packages/paperclip-runner/src/control-plane/durable-prp-control-plane.ts`)
keeps an input pending when `recoverSemanticToolInput` returns null.
`PaperclipRunnerToolAuthority.recover` returns null for every tool
without a durable receipt. Nothing else could settle the input, so
`semanticToolResultsSettled()` stayed false and `#closeOnce` in
`runnerd-codex-transport.ts` threw
`NativeSessionCloseUnrecoverableError`.
- The control plane now passes `admission` to
`recoverSemanticToolInput`: `this_controller` when this instance
dispatched the callback live, `earlier_controller` when it restored the
input from an earlier controller's journal. The field is not written to
the result command or the journal. A live dispatch leaves this record
when its result is journaled.
- New
`packages/paperclip-runner/src/control-plane/orphaned-tool-callback.ts`:
- `dispatchToolCallback` records the callbacks that this process runs,
and the ones it saw fail.
- `recoverToolCallback` replays a durable receipt first. Without one, it
settles an `earlier_controller` callback that this process does not run
as `tool_call_interrupted_by_restart` (error result, `outcome:
"unknown"`, `retryable: false`). A `semantic_tool_outcome_unknown`
rejection from the authority settles the same way, only under the same
owner-gone proof.
- `native-session-executor.ts`: `SessionAuthorityEpoch.execute` runs
through `dispatchToolCallback`. `SessionAuthorityEpoch.recover` runs
through `recoverToolCallback`. The three recovery call sites pass
`admission`.
- New ownership kind `native_completed_turn_cleanup_hold`
(`server/src/services/native-runtime/completed-turn-cleanup-hold-settlement.ts`,
registered in `recovery/ownership-registry.ts`). It lists a native run
that failed with `native_session_cleanup_quarantined` after its saved
checkpoint recorded a completed turn, and that has a system-recorded
no-replay hold. After `proveOwnerGone` proves the closing controller
gone (its in-process cleanup gate went with it), it settles each such
hold as `restored`, removes its replay block, and logs
`issue.recovery_action_resolved`. A hold that still protects files not
verified as saved stays for workspace recovery. Operator decisions are
never reopened. It starts no turn. `heartbeat.ts` registers the ordinary
resume path (`resumeRemoteStopComments`) for saved user input.
- Docs: `doc/execution-semantics.md` and
`packages/paperclip-runner/docs/durable-recovery.md`.

## Verification

- Red before the fix, green after:
-
`packages/paperclip-runner/src/control-plane/durable-prp-control-plane.test.ts`
"host-tool callback orphaned by a server restart". It uses the real
control plane and an authenticated runner. A callback starts 3 seconds
before the restart, the old controller retires with no result, the new
controller adopts the runner, the turn completes, and then recovery
runs. `paperclip_call_assigned_tool` and `connections_search` settle as
`tool_call_interrupted_by_restart`, the runner accepts the late result,
`semanticToolResultsSettled()` becomes true (the condition close
requires), and the tool is not dispatched again. Before the fix, 4 of 5
cases failed: recovery received no admission and the callback stayed
pending.
- `server/src/__tests__/completed-turn-cleanup-hold-settle.test.ts` uses
the staging shape of both holds (real Postgres, rows as earlier releases
saved them). Before the fix, the ownership reconciler did not list them
(4 of 4 failed), and the execution blocker was the files hold with
`canRetry: false` and `canContinue: false`. After the fix, both holds
settle as `restored`, the execution blocker is null, no run is created,
the task keeps `blocked`, and the next pass lists nothing.
- Safety cases:
- A callback that this process still runs stays pending. After it
finishes, the next recovery pass settles it.
- A callback that this controller dispatched and saw rejected stays
pending, as before.
  - A durable receipt is replayed and not replaced.
- Holds stay while the closing controller is alive (its gate may still
exist).
- A hold whose files are not saved stays; the run's other hold settles.
  - Holds of a run whose turn did not complete are never listed.
- Focused suites pass: `durable-prp-control-plane.test.ts` and
`runnerd-codex-transport.test.ts` (506 tests); runner adoption,
release-resume, semantic readiness, ACPX reconciliation and external
driver tests; `native-session-executor.test.ts` and
`native-runner-restart-recovery.integration.test.ts` (1496 tests);
`ownership-reconciliation-report.test.ts` and
`interrupted-preparation-hold-settle.test.ts`.
- `tsc --noEmit -p packages/paperclip-runner/tsconfig.test.json` passes.
`pnpm --filter @paperclipai/server typecheck` passes.
- `pnpm verify` returns exit 2 (a global doc input changed), so required
CI supplies the broad coverage.

## Risks

- Previous-release story: no persisted shape changes. `admission` is
computed at recovery and never saved. A journal that an earlier release
saved with a pending callback restores as `earlier_controller`, so that
session settles at its next adoption. Holds that earlier releases saved
settle on the reconciler's first pass after deploy. No migration.
- No double execution: recovery never calls the tool again. It replays a
durable receipt or reports an unknown outcome. The agent is told to
check the current state before it repeats the call. Hold settlement
starts no turn and replays nothing.
- The owner-gone proof for a callback: the new controller holds the
run's checkpoint fence, and the earlier controller retired its journal
writer. If the earlier process is still alive during an overlapping
deploy, it can still finish the tool, but it can never record a result
in this session. The unknown outcome is accurate in that case.
- Hold settlement requires `proveOwnerGone` on the closing controller's
stamp, because the cleanup gate lives in that process. On a server that
has not restarted since the quarantine, the holds stay.
- The in-process failure memory is bounded to 4,096 entries. Eviction
only lets a much older failed callback settle as interrupted later. It
never replays it.

DottaandClaude Opus 5.5 d06f43b14f fix(workspaces): settle a resolved no-replay hold once a sibling saved its files (#20641)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When a remote workspace save fails, recovery actions hold the task
until the files are saved
> - One failed run can have two holds: its export hold, and a no-replay
hold that a later "try again" opened for the same run
> - The no-replay hold is recorded resolved-but-blocked, and it is the
task's execution blocker
> - #20569 lets the export hold retry under the new symlink capture
policy and save the files
> - The sibling settlement that should then release the no-replay hold
only looked at active holds, so the task stayed blocked with no working
Retry
> - This pull request lets the sibling settlement and its discovery
include resolved no-replay holds
> - The benefit is that the task continues without a person once the
files are saved

## Linked Issues or Issue Description

Refs #20569

**What happened?**
On staging, a native run on a Daytona sandbox failed to save its
workspace (`remote_workspace_archive_unsafe_symlink`). Its export hold
(`native_workspace_sync_out_retry_exhausted`) was exhausted after 6
attempts and handed to the board. A user comment then opened a second
hold for the same run (`native_continuation_requires_reconciliation`,
`preserve_without_replay_v1`). That hold also failed 6 times and was
recorded `resolved` with outcome `blocked`. The task's execution blocker
is this second hold.

**Expected behavior**
After #20569 is deployed, the worker re-arms the export hold and saves
the files. The no-replay hold of the same run then settles, and the task
is no longer blocked.

**Steps to reproduce**
1. Create both holds with the exact staging evidence (see the new test
`stagingIncident`).
2. Run the recovery worker until nothing is due.
3. Before this change, the export hold completes, but the no-replay hold
stays `resolved`/`blocked` and `getExecutionBlocker` still returns it
with `canRetry: false`.

## What Changed

- `workspace-recovery-fallback.ts` (`settleSiblingRecoveredHold`): a
resolved no-replay hold (`isRetainedFileHold`) can now settle when a
verified receipt of a sibling action saved its run's files. Settling
removes `automaticRecovery`, so the hold stops blocking the task. It
starts no turn.
- `workspace-recovery-fallback-discovery.ts`: the worker discovers such
a resolved hold when a sibling of the same run is recovered.
- New test in `workspace-recovery-capture-policy.test.ts` with the exact
staging shape of both holds: board owner, `active_run_watchdog`, system
recovery policy version 1 without a capture policy version, stage
`restoring_files`, `export_interrupted` with cause `provider_error`, 6/6
attempts, `historicalWorkspaceSource` and `workspaceRestoreRecovery`
lease ids.
- `doc/execution-semantics.md`: states that a resolved no-replay hold
also settles from a sibling save.

## Verification

- Red before the fix: the new test failed. The no-replay hold stayed
`resolved`/`blocked`, and it stayed the execution blocker.
- Green after the fix: `npx vitest run --root server
src/services/workspace-recovery-capture-policy.test.ts` (3 passed). The
test drives the worker's own discovery (`nextWorkspaceRecoveryAt` +
`reconcileRetainedWorkspaces`) until nothing is due. It checks: the
export hold is re-armed once and saves the files; the no-replay hold is
`resolved`/`restored` by the sibling; `getExecutionBlocker` returns
null; the continuation hook ran when the task was free; no new run was
created; the worker goes idle.
- Related suites: `workspace-recovery-fallback`, `-admission`,
`-stop-proof`, `-source`, `-preparation`, `-preparation-gates`,
`execution-blocker-read`, `preserved-native-response-wait.integration`:
409 passed.
- `npx tsc --noEmit -p server/tsconfig.json`: clean.
- `pnpm verify` exits 2 (global doc input), so CI supplies the broad
coverage.

## Risks

- A resolved no-replay hold is now released when another action's
verified receipt saved the same run's files. The receipt check is
unchanged, so an unverified sibling still does not release it.
- Settling starts no turn. Waiting input and the run's own result
continue the task through normal admission, which still checks every
other hold.
- Previous-release story: holds saved by earlier releases need no
migration. The worker discovers them on its first pass after deploy.

DottaandClaude Opus 5.5 e3bc4ca798 fix(native): settle warm follow-ups that a restart left behind (#20631)
<!-- 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
> - Native warm runs on a remote sandbox continue the saved session of
the previous run. Admission first proves what happened to the previous
Runner.
> - A deploy restarted the staging server while warm Runners were idle.
Three follow-up runs then failed before provider work, each with a
different refusal, and their tasks stayed blocked.
> - The refusals asked for proof that a restart had made impossible. A
restart is a product failure, so recovery must settle it automatically
and keep the strict checks for real uncertainty.
> - This pull request accepts the proof that the restart leaves behind,
in three places: the warm owner on a replaced sandbox, the suspended
Runner with an undelivered suspend receipt, and the restore hold of a
run that saved nothing new.
> - The benefit is that these follow-up runs start, and state saved by
older releases carries forward without a migration.

## Linked Issues or Issue Description

Refs #20567, #20346

**What happened?**
On staging, a deploy replaced the webserver process at about 18:04 UTC
on 2026-11-10 (lease controller boot `348ec0bb` on one deployment, then
boot `3e84c195` on a new deployment that started at 18:04:16). Three
runs of one Codex agent on Daytona failed between 18:08 and 18:15:

1. A warm follow-up got a newly created sandbox. The previous warm
Runner stayed `ready` in its own retained sandbox. Live adoption denied
it with `runner_state_identity_mismatch:
prior_owner_terminal_state_indeterminate`
(`remote-warm-session-recovery.ts:127`), because only a resumed sandbox
may be adopted. The per-turn retirement path refused warm owners
(`lifecycle_not_per_turn`).
2. A warm follow-up resumed the same sandbox and directory. The previous
Runner had been suspended by the shutdown, but the controller stopped
before it acknowledged the suspend result. The Runner kept its terminal
fence (`pendingTerminalDelivery` for `runner.suspend`). The read refused
it with `native_controller_recovery_missing_evidence:runner_not_settled`
(`native-session-executor.ts:7032`).
3. A continuation into a fresh workspace failed with
`remote_workspace_recovery_receipt_invalid`
(`remote-workspace-recovery-attachments.ts:60`). Its predecessor had
restored the committed save, failed before provider work, and kept a
restore hold with no recovery receipt. Its saved reference named the
snapshot it restored.

**Expected behavior**
After a restart, the next run continues. It retires a finished owner
that nobody can adopt, reads a finished suspension, and skips a source
that left no unsaved files. Real uncertainty still refuses with a named
reason.

**Steps to reproduce**
1. Run a warm native Codex turn on a reusable Daytona sandbox and let it
commit.
2. Restart the server (deploy) while the Runner is idle.
3. Start the next turn. Get a new sandbox (case 1), or resume the same
sandbox after the shutdown suspended the Runner (case 2).
4. For case 3, continue a task whose previous run restored the last save
and failed before provider work, into a fresh workspace.

**Paperclip version or commit**
Staging before `2e3cbe57` (the runs predate that deploy). The gaps
remain on `master` at `9b21dcbd`.

## What Changed

- `inspectRemoteWarmSessionRecovery` returns `null` when this run's
sandbox is `created` or `replacement`. Such a sandbox holds no Runner to
adopt. The caller then uses ordinary admission.
- `inspectFinishedPerTurnRunnerdOwner` also retires a **warm** owner on
a remote sandbox runner when this run's sandbox is `created` or
`replacement`. It uses all the existing proofs: terminal run, committed
result, released coordinator lease, stopped or fenced controller,
settled journal, and quarantine copies. Local warm Runners and resumed
sandboxes keep the live path.
- `restoreRemoteSuspendedRunnerCheckpoint` accepts a suspended Runner
whose only open fence is its own undelivered `runner.suspend` receipt.
The fence must name `runner.suspend` with lifecycle `suspended`, it must
be the last controller command, and the restored journal must not name
that command differently. A provider cleanup, unsent events, a turn's
terminal fence or a warm transition still refuse with
`runner_not_settled`. A later authorized Runner process reconciles the
receipt, as the Runner already does.
- `attachPreservedRemoteWorkspaceSnapshots` skips a source with a
receipt-less restore hold when its saved reference names the exact
committed snapshot that its own succeeded `remote_workspace_restore`
loaded at the same epoch. Any other saved snapshot still needs the
canonical receipt.
- `doc/execution-semantics.md` describes the three rules.

## Verification

- Red (unfixed code), each in the exact staging shape:
- `native-recovered-owner-followup.test.ts` "retires a finished warm
owner left behind by a restart when this run's sandbox is
created/replacement" failed with `runner_state_identity_mismatch:
prior_owner_terminal_state_indeterminate`.
- `native-controller-recovery.integration.test.ts` "defers a remote warm
continuation…" failed: live adoption rejected a created/replacement
sandbox with the same error.
- `native-controller-recovery.integration.test.ts` "reads a resumed
sandbox's suspended Runner with an undelivered suspend receipt" failed
with `native_controller_recovery_missing_evidence:runner_not_settled`.
It reads through a sandbox runner that refuses paths outside the
workspace base.
- `workspace-recovery-preparation.test.ts` "decides a receipt-less
restore hold of a source that restored_unchanged" failed with
`remote_workspace_recovery_receipt_invalid`.
- Green: the same tests pass. Focused files pass:
`native-recovered-owner-followup.test.ts` and
`native-controller-recovery.integration.test.ts` (104 tests),
`workspace-recovery-preparation.test.ts` (85 tests).
- Safety cases (strict checks stay strict):
  - A warm owner on a resumed sandbox is not retired.
- A warm owner with an unsettled journal (pending command, unanswered
tool input) stays held and names `retirement_refused=journal_…`.
  - A warm owner whose finalization lease is still held stays held.
- A turn terminal fence, a provider cleanup, unsent events, a fence
behind a later command, or a journal that names the command differently
still fail with `runner_not_settled` and cache nothing.
- A restore-hold source that saved another snapshot, whose restore did
not succeed, or whose restore was at another epoch still fails with
`remote_workspace_recovery_receipt_invalid`.
- Neighbouring suites pass: `native-session-executor.test.ts`,
`plugin-runner-release-resume.integration.test.ts`,
`explicit-native-continuation.test.ts` and
`native-harness-filesystem-independence-continuation.integration.test.ts`
(1786 tests). The last one asserted the old warm refusal on a created
sandbox. It now shows that the warm follow-up resumes the same provider
session for the new run.
- `npx tsc --noEmit -p server/tsconfig.json` passes.
- `pnpm verify` returns exit 2, because a global doc input changed
(`doc/execution-semantics.md`). Required CI supplies the broad coverage.

## Risks

- Previous-release state: all three rules read state that earlier
releases already save (lease outcome, coordinator rows, Runner state in
the sandbox, journal commands, run results and workspace operations).
Rows saved by older releases carry forward. No migration.
- Case 1 starts a new Runner for a warm session whose old Runner may
still exist, idle, in its retained sandbox. Its controller is gone and
its result is committed, so it can accept no new commands. The provider
session follows the existing resume-or-replace policy.
- Case 2 trusts a suspend fence only in the exact shape that the Runner
writes before it sends the result. Other fences still refuse.
- After case 1, a warm follow-up resumes from its own warm checkpoint.
That checkpoint carries no replacement policy, so a failed provider
resume is still reported as `native_session_recovery_failed` and is not
replaced. This is the existing warm behavior.
- Case 3 skips a source only when it provably saved nothing beyond a
committed snapshot. That snapshot stays in its own workspace.
- The three tasks that already failed stay blocked until their next wake
or a user message. This PR does not add an automatic continuation for a
completed no-replay hold. A follow-up can add that.
- `native-runner-restart-recovery.integration.test.ts` (runs only with a
runner container) no longer probes a replacement sandbox, because that
probe now retires the owner by design.
- Not verified live on Daytona.

DottaandClaude 24661683db fix(recovery): bootstrap a remote follow-up that a restart cut before its Runner launched (#20642)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - After a control-plane restart, restart recovery classifies each
claimed native run: reattach a live Runner, resume from a checkpoint, or
bootstrap again when durable records prove no provider work
> - A follow-up run on a continued session gets a rebound admission
checkpoint. It names the new run, but it keeps the previous turn's
provider session ID
> - Recovery read that copied provider session as this run's provider
work. A follow-up killed after `native.process_start_requested` but
before its remote Runner launched was classified
`reattach_remote_runner`
> - The reattach then had no Runner to find, failed with
`native_continuation_requires_reconciliation`, and the task needed Retry
> - This pull request stops the copied session from counting as this
run's work, and keeps the existing durable proofs as the authority
> - The benefit is that these restarts bootstrap again by themselves and
do not repeat provider work

## Linked Issues or Issue Description

**What happened?**
Two Daytona restart-chaos tasks needed a Retry click:
- Wave `w-20261110T173243-s9202` t02 (claude C1, K2): the follow-up run
was killed at `stage.asset.home`, after
`native.process_start_requested`. Recovery chose
`reattach_remote_runner`. Verification failed with
`native.remote_runner_recovery_failed {stage: runner_state, reason:
state_read_failed}` (`runner_remote_state_unavailable: exit=1`):
`runner-state.json` did not exist because the Runner never launched. The
storage fault window (ST7) had ended 30 s before, so it was not the
cause.
- Wave `w-20261110T174930-s9205` t04 (codex C1, RR1): the scheduled
retry of a `process_lost` run was killed at
`session.checkpoint.restore`, after `native.process_start_requested`.
Recovery chose `reattach_remote_runner`. Verification failed with
`native_remote_recovery_lease_mismatch: stage=runner_verification
field=identity_run_id`: the local Runner identity belonged to the
previous run, because this run's Runner never started.

**Expected behavior**
A run whose durable records prove that no Runner received a provider
turn bootstraps again without a person.

**Steps to reproduce**
1. Start a remote follow-up run on a continued session (for example, a
comment after a completed turn).
2. Kill the server after `native.process_start_requested` and before the
remote Runner launches.
3. Observe `reattach_remote_runner`, a failed verification and a Retry
banner.

**Paperclip version or commit**
master close to `6d6b2d0e` (waves); still reproduced by the new tests on
master `90dd864bff`.

## What Changed

- `native-restart-recovery.ts`, no controller checkpoint for the run
(`remote_runner_never_received_commands`): a follow-up with
`sessionIdBefore` qualifies when it carries only its continued-session
checkpoint, and a predecessor's settled Runner identity
(`carriesInheritedRunnerIdentity`) no longer disqualifies it. A recorded
process identity, a Runner-sent event, a provider event or a pending
request still keeps the run held.
- `native-restart-recovery.ts`, controller checkpoint exists: the
existing Postgres proof (`nativeRunnerCheckpointRemoteBootstrapProof`)
now also runs when the run carries only a rebound checkpoint whose
provider session a settled earlier run of the same session saved
(`carriesSettledPredecessorSession`). The copied provider session then
does not count as this run's provider evidence. The controller
checkpoint stays the authority: any turn command or turn event keeps the
run held.
- `doc/execution-semantics.md`: describe the rule.

## Verification

-
`server/src/services/native-runtime/native-runner-restart-recovery.integration.test.ts`
(real Postgres):
- "restarts a follow-up whose controller never saved a checkpoint (s9205
t04)" and the variant "with its predecessor's remote runner identity":
red on master (`reattach_remote_runner`), green now.
- "restarts a follow-up whose saved controller checkpoint proves no
provider turn (s9202 t02)": red on master, green now.
- Held cases stay held: own recorded Runner identity, a carried active
turn, a provider session that no settled earlier run saved, a
`turn.start` command, a projected `turn.started` event.
- Whole file: 171 passed.
- `npx tsc --noEmit -p server` passes.
- The executor's existing `bootstrap_incomplete` path handles both
shapes: a scoped root that belongs to the previous run goes through the
existing prior-owner verification, and a root of this run restored from
the controller checkpoint goes through
`runnerdStateProvesIncompleteBootstrap` /
`runnerdStateProvesNoRemoteProviderTurn`.

## Risks

- A run with any recorded Runner process, Runner-sent event, provider
event, turn command or pending request keeps today's reattach or hold.
- A bootstrap claim charges one provider attempt, as today. The bounded
limit (3) still applies.
- No persisted shape changes.

DottaandClaude Opus 5.5 fd6e71a7ff fix(native): restore a warm backup when its source sandbox is idle (#20627)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs on remote sandboxes keep a warm sandbox and a verified
harness backup so the next run continues the same provider session
> - A run that starts while the previous run's workspace export is still
saving gets a new (created) sandbox lease, because reuse skips an
exporting sandbox
> - When that run prepares the harness, it finds a backup but no
recorded reusable lease, and it fails closed with
`runner_harness_state_mismatch: backup_without_reusable_lease`
> - #20278 accepted a destroyed source and a settled restore hold as
retired backup sources, but not an idle warm source that is still
`retained` for reuse
> - This pull request accepts an idle warm source under the same proofs,
claims it so it is never resumed again, and covers the resumed lease
that the failed run leaves behind
> - The benefit is that these recoveries continue the same session
automatically instead of blocking the task

## Linked Issues or Issue Description

Refs #20278

**What happened?**
A monitor wake started about 90 seconds after the previous run on the
same task finished. The previous run's warm sandbox lease was `retained`
with policy `reuse_by_environment`, but its workspace export was still
saving. Reuse skipped it and created a new sandbox. Workspace
realization waited for the export (about 136 s) and restored the saved
files. Then harness preparation found the previous run's backup (its
lease stamp names this exact manifest, and no provider work followed
it). The source lease was not destroyed and was not a restore hold, so
the run failed with `native_session_recovery_failed: Error:
runner_harness_state_mismatch: backup_without_reusable_lease` and the
task was blocked.

**What did you expect?**
The run continues the same provider session. The idle source sandbox
holds exactly the backed-up state, so restoring the backup into the new
sandbox is safe.

**Steps to reproduce**
1. Finish a warm native run on a remote sandbox. Its workspace export is
still saving.
2. Start the next run on the same task before the export settles.
3. Reuse skips the exporting sandbox and creates a new lease. Harness
preparation fails with `backup_without_reusable_lease`.
4. A retry resumes that new lease, which has no harness state, and fails
with `resumed_unavailable`.

## What Changed

- `native-retired-backup-source.ts`: an idle warm source is a third
retired backup source. It must be `released` or `retained` with policy
`reuse_by_environment`, its own run must be terminal and not the current
run, and it must have no cleanup in flight, no restore hold or pending
shutdown settlement, and no pending native workspace export. The backup
stamp, single-owner chain, and later-provider-work checks still apply.
- Before the restore, the idle source is claimed with a compare-and-swap
on the checked row. The claim moves its `reusableSandboxLease` scope
into a `reusableSandboxLeaseSuperseded` receipt. Reuse never resumes
that older state again, and the next acquisition treats it as obsolete
and destroys it. If a run resumed or changed the source first, the claim
matches no row and the backup is not restored.
- `environments.ts`: a cross-run reuse handoff now requires that the
source row has no superseded receipt. The supersede claim and the
handoff compete on the same row, so an acquisition that selected the
source before the claim cannot resume it afterward.
- The proof now rejects a backup whose source is the target allocation
itself (`targetProviderLeaseId`).
- `native-session-executor.ts`: a resumed lease whose sandbox has no
harness state at all (`unavailable`) restores the backup under the same
proof. This recovers the lease that the failed run left behind, so rows
saved by older releases recover after deploy without a migration.
- `doc/execution-semantics.md`: documents the idle-source rule, the
supersede claim, and the resumed stateless lease.

## Verification

- Red before the fix, green after:
- `native-session-executor.test.ts` "restores a warm backup into a
created lease only when an idle warm source finished its run and its
export" failed with `backup_without_reusable_lease`.
- "... a resumed lease never held the session and the warm source is
idle" failed with `resumed_unavailable`.
- `native-retired-backup-source.integration.test.ts` (real Postgres)
"authorizes an idle retained/released warm source and claims it as
superseded" failed (returned false).
- Integration test "refuses a reuse handoff of a source superseded while
its provider resume was pending" fails without the handoff guard and
passes with it.
- Safety rows stay refused: source run still running, workspace export
pending, cleanup in flight, restore into its own allocation, stamp names
another checkpoint, provider work after the backup, two host leases for
one allocation, claim lost to another run, and a resumed lease that lost
its own state. Existing destroyed-source and restore-hold rows are
unchanged.
- `cd server && npx vitest run
src/services/native-runtime/native-session-executor.test.ts
src/services/native-runtime/native-retired-backup-source.integration.test.ts
src/services/native-runtime/remote-warm-session-recovery.test.ts` passes
(1408 tests).
- `npx tsc --noEmit -p server/tsconfig.json` passes.
- `pnpm verify` exits 2 because a global CI input
(`doc/execution-semantics.md`) changed. Required CI supplies the broad
coverage.

## Risks

- Previous-release story: no persisted shape changes. Lease rows saved
by earlier releases carry forward. The new
`reusableSandboxLeaseSuperseded` metadata key is additive.
- The idle source is destroyed at the next acquisition for its
workspace. Its state is the verified backup, which the restored lease
now holds, so no work is lost.
- Not covered: when the source cannot be proven retired or idle (for
example a live owner or later provider work), the run still fails closed
with the same named code. An automatic fresh-session fallback for that
case is not in this PR.
- The root trigger (reuse skips a sandbox while its export saves, then
waits for that export) is unchanged. This PR does not change the reuse
lookup.

DottaandPaperclip 76c787fffc fix(runner): report monitor notes length limits (#20604)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents use task monitors to resume a future check.
> - The monitor schema limits notes to 500 characters.
> - The field description did not state the limit. Rejection showed only
the schema path.
> - This pull request adds the limit to the description and to safe
length errors.
> - Agents can correct notes before they retry a rejected call.

## Linked Issues or Issue Description

Related prior fix: #16868.

**What happened?**

A native `set_task_monitor` call with 501 characters in `monitor.notes`
failed with a path that ended in `notes/maxLength`. The error did not
state 500. The schema already had `maxLength: 500`, but the field
description did not state it.

**Expected behavior**

State the limit in the field description and in the rejection. Accept
500 characters. Reject 501 characters before dispatch. Preserve a saved
monitor when a replacement is invalid.

**Steps to reproduce**

1. Supply a future `monitor.nextCheckAt` and 501 characters in
`monitor.notes`.
2. Read the native provider error.
3. Before this fix, it shows the constraint path without the maximum.

**Paperclip version or commit**

Reproduced on `7368a0b15c2f02107778a961144d86e2eb59a952` in a Linux
source checkout, with Node 25.9.0 and Rust 1.97.1.

## What Changed

- Use one local value for the published notes limit and its description.
The server test checks agreement with the persisted shared validator.
Keep the standalone Runner package boundary.
- Read the numeric maximum from the authorized JSON Schema validation
error. Keep submitted values private and preserve the 512-byte feedback
bound.
- Test the published schema and real bridge dispatch path at 500 and 501
characters. Test saved contents and rejection without monitor changes
with real PostgreSQL.
- Refresh generated contracts and document the limit.
- Sync two SDK proof lock identities after the reviewed master lock
refresh in #20615. This fixes the remaining CI proof mismatch. Keep
compiler, parser, Zod, and all rejection checks unchanged.

## Verification

- Final head: `bac60234ab3a8fc7043a90c7f9c81b02e250428b`.
- Red: the server regression failed because the field description
omitted `500`. The Rust regression failed because the error omitted
`maximum 500 characters`.
- Local passes after the final base update: 44 PostgreSQL
monitor/scheduler tests, 14 real-source Rust bridge tests, 11
cache/Docker guard tests, and 56 SDK proof tests. Runner TypeScript
build and generated contract checks pass.
- The focused Rust check compiles the actual source in a small Cargo
workspace. The full Rust CI suites also pass on Linux and Windows.
- Final-head [PR CI
run](https://github.com/paperclipai/paperclip/actions/runs/42881633978)
passes. This includes typecheck, build, Runner support, Runner Rust and
Vitest, server tests, serialized tests, and all eight e2e shards.
- Final-head [Windows Rust
run](https://github.com/paperclipai/paperclip/actions/runs/42881633419)
passes.
- Greptile: 5/5 on the final head, with no open findings. There are 61
successful checks and five conditional skips. The separate Paperclip
Review remains queued; its comment says work is paused. No CI or test
check is pending or failed.
- `pnpm verify` returned exit 2 and selected broader CI. The full local
suite was not run. Final-head CI supplies that coverage. Earlier failed
attempts were repaired and are not counted as passes.

## Risks

- Low risk. The existing 500-character bound, scheduling semantics, and
permissions stay in place.
- Length feedback uses only a schema path and numeric bound. It does not
print submitted text.
- The Runner binary and tool contracts must reach an instance for the
new guidance to apply. This PR does not deploy or merge.

## Model Used

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

DottaandClaude Opus 5.5 38944cff1a fix(environments): retry and safely replace a reusable sandbox that will not resume (#20626)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A task that runs on a reusable (warm) cloud sandbox resumes the same
sandbox on the next wake
> - When a follow-up arrives while the provider is auto-stopping or
archiving the idle sandbox, the resume can fail
> - Each failed attempt waited the provider's whole five-minute start
deadline and then failed with `reusable_sandbox_resume_failed`, even
when the workspace was saved and nothing lived only on the sandbox
> - Two such runs in a row made a user wait for many minutes and
recorded two failed runs
> - This pull request bounds the resume, retries a state change inside
the run, and replaces the sandbox from the saved snapshot when that is
safe
> - The benefit is that recovery works automatically and the first turn
is not delayed by minutes

## Linked Issues or Issue Description

**What happened?**
Two consecutive runs failed before provider dispatch with: `Reusable
sandbox lease "<id>" could not be resumed (cause=provider_error); the
lease was preserved and no replacement was created.` Each run took about
5.5 minutes (320s and 330s) in preparation. The third run resumed the
same sandbox from `stopped` in 4.7 seconds after the provider settled.
The previous run had ended with a clean final save and a verified
harness backup.

**Steps to reproduce**
1. Let a task's reusable sandbox go idle so that the provider auto-stops
or archives it.
2. Send a follow-up while the provider still reports the sandbox as
changing state.
3. The Daytona worker waits in `ensureSandboxStarted` until its 300s
start deadline and throws "is still <state> at its start deadline". The
host does not classify that as transient and it has no safe fallback, so
the run fails.

**Expected behavior**
The run retries briefly. If the sandbox still cannot start and nothing
lives only on it, the run continues on a replacement sandbox that
restores the saved workspace.

**Root cause**
`server/src/services/environment-runtime.ts` (reusable resume block,
about line 1820): the resume deadline was the provider's full start
deadline (300s plus RPC margin), the transient classifier did not
recognize a state transition, and the catch always threw
`ReusableSandboxResumeError`. #20212 waits out a state change inside the
same 300s start deadline, so it covers the start but not the time budget
or the fallback.

## What Changed

- Add `server/src/services/reusable-sandbox-resume-replacement.ts`:
- `REUSABLE_SANDBOX_RESUME_BUDGET_MS` (90s): the total resume time for
one run, retries included.
- `sandboxStateTransitionFailure`: "state change in progress" and "is
still <state> at its start deadline" are transient.
- `retireUnresumableReusableSandboxLease`: replace only when the lease
is `released`/`retained` with no live owner, the task workspace is clean
with a committed saved snapshot and no other writer, and a
`paperclip_runner` session has a verified lease-bound harness backup.
Access refusals (401/403) and an unavailable worker stay strict. After
the replacement lease (which carries the harness backup) is recorded,
the old lease moves to `pending_cleanup` (reason `resume_failed`) in one
guarded write, so the existing cleanup sweep destroys the old sandbox
and no provider delete runs before the first turn. A failed creation or
a restart before that write leaves the old lease `retained` for the next
attempt.
- `environment-runtime.ts`: cap the resume deadline at the budget, treat
a state transition as transient, and call the replacement policy before
failing. A replacement records `sandboxLeaseAcquisition: { outcome:
"replacement", reason: "resume_failed" }`; workspace preparation then
restores the saved snapshot.
- `remote-workspace-transport.ts`: add the closed failure label
`sandbox_state_transition`, so a strict failure names the cause instead
of `provider_error`.
- `doc/execution-semantics.md`: document the budget, the in-run retry,
the replacement conditions, and the strict cases.
- Update the two slow-start tests: the resume RPC timeout is now 90s
instead of 330s/150s. A 61s start still resumes the same sandbox.

## Verification

- Red before the fix (new file
`server/src/__tests__/environment-runtime-reusable-resume-replacement.test.ts`,
staging shape: lease created by the real acquisition path, then retained
after a clean save with a backup stamp, 300s provider deadline, worker
refusal with no status): 3 tests failed with `could not be resumed
(cause=provider_error); the lease was preserved and no replacement was
created.`
- Green after the fix: 10/10 pass, including a case where the
replacement creation fails and the next run replaces the sandbox with
the backup carried forward. The safe case replaces the sandbox, keeps
every resume RPC at or below 90s, makes no synchronous destroy call, and
moves the old lease to `pending_cleanup`. A single state-change refusal
resumes the same sandbox inside the run. Six strict cases keep the lease
and fail with `cause=sandbox_state_transition`: unsaved work, no saved
version, an uncommitted saved version, a live owner, no verified backup,
and a 403.
- `pnpm exec vitest run src/__tests__/environment-runtime.test.ts` (197
pass), `heartbeat-retry-scheduling`, `legacy-execution-recovery`,
`remote-workspace-transport` (251 pass).
- `tsc -p server/tsconfig.json --noEmit` passes.
- `pnpm verify` exits 2 (a doc change is a global CI input). Required CI
supplies the broad coverage.
- Not run: a live Daytona run on staging. The provider message is kept
off the run record, so the exact transition state on staging (stopping
or archiving) is inferred from timing, not observed.

## Risks

- A strict resume now gives up after 90s instead of 300s. The provider
start continues in the background, and the bounded bootstrap retry
resumes the same sandbox. A stopped sandbox resumes in seconds and an
archived one in about 25s on Daytona, so 90s leaves headroom.
- A replacement leaves the old sandbox to the cleanup sweep. If the old
start finishes later, the sweep still destroys it. The guarded write
only claims a `released`/`retained` lease with no live owner.
- Upgrade safety: no new persisted fields are required. Leases saved by
older releases are read with the same rule; one without a verified
backup stays strict. The replacement reason `resume_failed` already
exists in the acquisition outcome.

DottaandClaude Opus 5.5 9b21dcbdda refactor: remove SPEC docs and repoint spec citations (#20565)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Contributors and agents read the docs under `doc/` before they
change code
> - `doc/SPEC.md` and `doc/SPEC-implementation.md` were out of date.
`doc/SPEC-implementation.md` became an append-only log: in 60 days it
got about 1,645 new lines and lost 181, across 140 commits
> - #20557 changed `AGENTS.md` so the code and its tests are the source
of truth, and the specs are only background
> - This pull request removes the two spec docs. It moves only the
sections that live code comments cite into focused docs, and it repoints
all other references
> - The benefit is one less stale document that agents read and append
to

## Linked Issues or Issue Description

Refs #20557 (merged). This PR is the follow-up that removes the docs. It
is based on `master`, which already contains #20557.

**Issue type**
Outdated content. The docs are out of date and conflict with the code.

**Where is the issue?**
`doc/SPEC.md`, `doc/SPEC-implementation.md`, and the code comments and
docs that cite them.

**What's wrong?**
`doc/SPEC.md` and `doc/SPEC-implementation.md` are out of date, but
agents still read them and append a paragraph with each fix.

**Suggested fix**
Delete both files. Move the sections that code cites into focused docs.
Repoint the references.

## What Changed

- Deleted `doc/SPEC.md` and `doc/SPEC-implementation.md`.
- Moved these spec sections, because live code comments cite them:
- §9.3.1 "Shared default-open issue writes" → new section in
`doc/agent-permission-defaults.md`.
- §9.8.1 "Issue-thread interaction resolver contract" →
`doc/execution-semantics.md`, "Issue-thread interaction resolution".
That section already had most of the contract. I added only the missing
parts: the `supersedeOnUserComment` default, the canonical policy list,
the addressee and cap rules, the rule that surfaces show the server's
effective audience, and the cross-issue budget charge. The short policy
summary at the top of the section now points to the list, so the
definitions occur one time only.
- §9.9 "Task Watchdog Authority Contract" → new "Authority contract"
section in `doc/TASK-WATCHDOG.md`. It holds the allowed and disallowed
mutation lists and the deferred capabilities. The atomic recovery batch,
restoration verification, and interaction rules were already in
`doc/execution-semantics.md` §11, so the new section links there and
does not repeat them. I did not move the "Downstream acceptance
criteria" checklist or the sentence about the CTO and Security sign-off.
These were implementation-time notes; the tests now hold that coverage.
- §9.10 "Company Skill Policy Contract" → new
`doc/company-skill-policy.md`. No focused doc had this contract. I did
not move the "Required regression tests" phase checklist.
- Did not move any other part of the specs.
- Repointed code comments that cited spec sections:
- `packages/shared/src/issue-write-denial.ts` (§9.3) →
`doc/agent-permission-defaults.md`
- `server/src/routes/issues.ts` (§9.9) → `doc/TASK-WATCHDOG.md`,
"Authority contract"
- `server/src/routes/issues.ts` (§9.3, §9.8.1 cross-issue budget) →
`doc/agent-permission-defaults.md`
- `ui/src/lib/interaction-audience.ts` and
`ui/src/components/InteractionGovernancePanel.tsx` (§9.8.1) →
`doc/execution-semantics.md`
- `ui/src/lib/skill-policy-denial.ts`, `ui/src/pages/CompanySkills.tsx`,
`ui/src/pages/CompanySkills.production.tsx`,
`ui/src/pages/SkillStudio.tsx` (§9.10) → `doc/company-skill-policy.md`
- `server/src/services/recovery/ownership-invariant-report.ts` (monitor
deadline wait path) → `doc/execution-semantics.md` §8. That section
already lists the one-shot monitor as a valid wait path.
- Resynced the git blob pin for
`packages/shared/src/issue-write-denial.ts` in
`tests/runner-e2e/source-sdk-public-inputs.json`. The comment edit
changed the file's hash, and the Runner support suite checks that pin. I
used `node tests/runner-e2e/source-sdk-public-inputs.mjs <HEAD>
--write`; only that one pin changed.
- Updated `AGENTS.md` §1 so it does not name the deleted files.
- Removed the links to the deleted files from
`doc/plugins/PLUGIN_SPEC.md`.
- Updated the `doc-maintenance` agent skill
(`.agents/skills/doc-maintenance/`) so it no longer audits or stages
`doc/SPEC.md`.
- Removed or replaced references in `maps/README.md`,
`maps/feature-map/README.md`, `maps/storybook-map/README.md`,
`doc/PRODUCT.md`, `doc/CLIPHUB.md`, `doc/DEPLOYMENT-MODES.md`,
`doc/DEVELOPING.md`, `doc/evals.md`, `doc/spec/agent-runs.md`,
`doc/AGENTCOMPANIES_SPEC_INVENTORY.md`,
`doc/connections/CONNECTOR-PLAYBOOK.md`,
`doc/plugins/ideas-from-opencode.md`, `doc/execution-semantics.md`,
`doc/TASK-WATCHDOG.md`, and `.devin/wiki.json`.
- In `doc/execution-semantics.md`, the "admission is independent of
cleanup and accounting" reference now states the rule inline: only a
hard stop, an explicit pause, or an inactive company refuses admission.
- Kept these references as they are: dated plans in `doc/plans/` and
`docs/plans/`, the dated log
`doc/logs/2026-05-24-cli-api-parity-e2e-log.md`, `releases/`, the
transcript fixture `ui/src/fixtures/runTranscriptFixtures.ts` (it uses
the filename only as sample text), and
`docs/specs/external-task-protocol.md` (it refers to the Symphony
project's own `SPEC.md`).

## Verification

- `git grep -n "SPEC-implementation\|SPEC\.md"` (without `releases/`,
and ignoring `PLUGIN_SPEC.md` citations) finds only the kept references
listed above.
- `grep -rn "§9\.\(3\|8\|9\|10\)" ui/src server/src packages/shared/src`
finds no results.
- `node scripts/check-maps.mjs`: "Maps aligned: 35 areas, 192 capability
IDs".
- `pnpm check:token-gates`: "All gates clean".
- `pnpm exec vitest run --config tests/runner-e2e/vitest.config.ts
tests/runner-e2e/source-sdk-public-type.test.ts
tests/runner-e2e/source-sdk-evidence.test.ts`: 45 passed. These failed
in CI before the pin resync.
- `pnpm verify`: exit 2 ("Broader verification required") because
`AGENTS.md` is a global CI input. Required CI supplies the broad
coverage for this revision.
- All code changes are comments only. No runtime behavior changes. The
title uses `refactor:` because comments in source files changed.

## Risks

- Low risk. The change removes docs and edits comments only.
- A reader can lose context from spec sections that I did not move. The
text stays in git history. The code and its tests are the source of
truth.
- External links to the two deleted files will return 404.

DottaandClaude Opus 5.5 86cc3e3a11 fix(workspaces): save remote workspaces that contain outside symlinks (#20569)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents on a remote sandbox (for example Daytona) save their
workspace after each run, and recovery retries a failed save
> - The save refused the whole workspace when one symlink was absolute
or pointed out of the workspace
> - Ordinary agent work makes such links: a headless Chromium profile
links `SingletonSocket` by absolute path into `/tmp`
> - Recovery then spent its full budget on the same refusal, handed the
hold to the board, and the task stayed blocked
> - This pull request keeps confined links, records and omits outside
links, and retries saves that an older policy exhausted
> - The benefit is that these saves succeed and blocked tasks continue
without a person

## Linked Issues or Issue Description

**What happened?**
On staging, a native run (OpenCode on `paperclip_runner`, Daytona
sandbox) built Storybook and drove Chromium with
`--user-data-dir=<workspace>/.review-chrome`. Chromium wrote
`.review-chrome/SingletonSocket ->
/tmp/.org.chromium.Chromium.*/SingletonSocket`. The save failed three
times with `remote_workspace_archive_unsafe_symlink`
(`native_workspace_sync_out_retry_exhausted`). System recovery then
tried six more times. It recorded each failure as `export_interrupted`
with cause `provider_error`, became `exhausted`, and gave the hold to
the board. The task and its parent stayed blocked.

**Expected behavior**
The save succeeds for an ordinary workspace that contains symlinks.
Links inside the workspace stay links. Absolute and escaping links are
dropped and recorded, and are never followed. Holds that an earlier
release exhausted recover automatically after deploy.

**Steps to reproduce**
1. Create a workspace with `node_modules/.bin/tool -> ../tool/cli.js`,
an absolute link to a file outside the workspace, and a link `escape ->
../outside/file`.
2. Capture it with `captureRemoteWorkspaceArchive` (or the serialized
sandbox helper).
3. Before this change, the capture fails with
`remote_workspace_archive_unsafe_symlink`.

## What Changed

- `remote-workspace-snapshot-archive.ts`: capture records an absolute or
escaping symlink in the manifest `excluded` list and omits it, instead
of failing the save. It never follows a link. Confined links are kept.
Restore validation is unchanged and still refuses an archive that names
an outside link.
- Added `REMOTE_WORKSPACE_CAPTURE_POLICY_VERSION = 2`. Each new system
recovery generation records `capturePolicyVersion`. Generations without
the field count as version 1.
- New `workspace-recovery-capture-policy.ts`: an exhausted save whose
last failure was in `preserve_files` (`export_interrupted`) under an
older capture policy gets one new bounded generation. Restore refusals
(`archive_unsafe`) are not re-armed, because restore validation is
unchanged. It shares the run-over guard (`sourceRunProvablyOver`) with
the stop-proof re-arm. It writes a `capturePolicyRecovery` marker and
`issue.workspace_recovery_rearmed` activity with reason
`capture_policy_changed`. The new generation has the current version, so
the rule cannot repeat for it.
- The recovery worker discovers these holds
(`capturePolicyRearmPendingCondition` in `nextWorkspaceRecoveryAt` and
the obligations query).
- Docs: `doc/native-workspace-finalization-recovery.md` (symlink policy)
and `doc/execution-semantics.md` (capture-policy re-arm).

Previous-release story: archives saved by the previous release never
contain outside links, and restore of them is unchanged. Recovery state
saved by the previous release has no `capturePolicyVersion`; it is read
as version 1 and, if exhausted in `preserve_files`, is re-armed once on
the first worker pass after deploy. No migration is needed. A capture
already in flight at the cutover uses the helper that its operation
installed; the next attempt installs the new helper.

## Verification

Red before the fix (same tests, unfixed code):

- `remote-workspace-snapshot-archive.test.ts` "keeps confined links and
drops outside links" (local and serialized helper): failed with
`remote_workspace_archive_unsafe_symlink`.
- `remote-workspace-transport.test.ts` "saves a workspace with outside
links through the sandbox helper" (split and Daytona one-shot output):
failed with `remote_workspace_archive_unsafe_symlink`.
- `workspace-recovery-capture-policy.test.ts` "retries once under the
new policy": failed, because the worker did not discover the exhausted
hold (`nextWorkspaceRecoveryAt` returned null).

Green after the fix:

- `npx vitest run --root server
src/services/remote-workspace-snapshot-archive.test.ts
src/services/remote-workspace-transport.test.ts
src/services/workspace-recovery-capture-policy.test.ts`: 271 passed.
- The recovery test uses the exact staging evidence shape (6 attempts,
`export_interrupted`, `provider_error`, board owner, no policy version).
It ends `complete` and `recovered`, saves a snapshot, and leaves the
source untouched.
- Safety cases: the archive does not contain the outside bytes; restore
refuses a hand-made archive with an escaping link; a hold exhausted
under the current policy is not re-armed and no sandbox resume is
attempted.
- `npx tsc --noEmit -p server/tsconfig.json`: clean.
- `pnpm verify`: see CI for the broad selection.

## Risks

- A tracked symlink that is absolute or escaping is now omitted. After
restore it shows as a deletion in `git status`. Before, the whole save
failed.
- On deploy, every hold exhausted in `preserve_files` with
`export_interrupted` gets one more bounded recovery generation,
including holds that failed for provider reasons. This is one generation
per hold per policy version.
- The manifest exclusion label stays
`paperclip.remote-workspace-exclusions.v1`. Workspaces that the old
policy accepted produce the same manifest, so unchanged-snapshot reuse
still works.

DottaandClaude c37eacbee3 fix(native): Retry re-finalizes a saved result that ran out of finalization retries (#20578)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs save an accepted result. Then a finalizer applies that
result to the task.
> - Finalization has its own budget of 3 failed attempts (#20555). When
the budget runs out, the coordinator goes to `terminal_failure` with
`native_finalization_retry_exhausted`.
> - For a provider-succeeded run, the task then rests `in_review` with a
board recovery card. The task shows "resolved" and offers no Retry. The
user is stuck.
> - The ordinary Retry is also wrong here: it starts a new provider run,
which repeats work the agent already finished.
> - This pull request adds two things. First, contention failures on
such a result get two longer automatic delays before the board gets the
task. Second, when the state is still exhausted, the task offers Retry,
and that Retry applies the same saved result again.
> - The benefit: fewer tasks need a Retry, and when one does, Retry
works and does no duplicate provider work.

## Linked Issues or Issue Description

Refs #20555 (it names this gap under Risks).

**What happened?**
In restart-chaos wave `w-20261110T044338-s20385`, task t03 ended with a
succeeded run, an accepted result, and a coordinator in
`terminal_failure` / `native_finalization_retry_exhausted`. The issue
stayed `in_review` with a board-owned `active_run_watchdog` card and
`canRetry=false`. #20555 stopped the early exhaustion. A real exhaustion
still leaves the same stuck state. Coordinators that older builds
already left in this state are stuck the same way.

**Expected behavior**
Transient finalization failures recover by themselves when that is safe.
When they do not, the task offers Retry. That Retry re-finalizes the
saved result. It does not start a provider run and does not charge a
provider attempt.

**Steps to reproduce**
1. Let a native run save an accepted result and end `succeeded`.
2. Make each finalization of that result fail until the budget of 3 runs
out.
3. Before this fix, the task presentation is `resolved` with
`canRetry=false`, and the board card has no action that applies the
result. The new test
`server/src/__tests__/native-exhausted-finalization-retry.test.ts`
reproduces this.

**Paperclip version or commit**
master at c58356003f (after #20555).

## What Changed

- `native-run-finalizer.ts` (`recordRetryableFailure`): when the budget
runs out on an accepted result of a provider-succeeded run, and the
cause is contention (`status_cas_exhausted` or
`side_effect_planning_failed`), the coordinator stays
`retryable_failure`. It tries again after 2 minutes, then after 10
minutes, each with a fresh budget. Each delay is recorded once in
`recoveryHistory` (`automatic_finalization_backoff`). After both delays,
the old terminal path runs. Deterministic causes (for example
`native_finalization_invalid`) and workspace-scope failures are
unchanged. The existing deadline worker (`native-result-commit-work`)
runs the retry, so no new timer or poll is added.
- New `native-runtime/exhausted-finalization-retry.ts`:
- `exhaustedNativeFinalizationCondition()`: one SQL predicate for
"succeeded native run, accepted result, coordinator `terminal_failure`
with `native_finalization_retry_exhausted`, no lease, no successor".
- `rearmExhaustedNativeFinalization()`: under the task lock, reopens the
same coordinator (`arbitrating` or `workspace_finalizing`), records
`exhausted_finalization_retry` in `recoveryHistory`, resolves the board
card (`handed_back`), and resets `finalizationFailureCount` to 0. It
sets a 30 s fallback `nextAttemptAt`, so the deadline worker finishes
the job if the process stops first.
- `refinalizeSavedNativeResult()`: runs `finalizeNativeRun` for the same
run with `preserveProviderAttempt: true`. A failure goes through the
finalizer's normal bounded budget.
- `task-interruption-presentation.ts`: the run read adds
`nativeFinalizationRetry` from that predicate. A succeeded run with this
flag shows `state: "failed"`, `canRetry: true`. It also adds
`nativeFinalizationRetryPending` (`savedResultRetryPendingCondition()`:
coordinator not committed or terminal, with an
`exhausted_finalization_retry` entry). While it is true the task shows
`state: "working"` with `recoveryStep: "finishing_recovery"`, so the
user sees the Retry took effect. Done or cancelled tasks, user gates,
and ordinary runs are unchanged.
- `task-retry.ts` (`admitTaskRetry`): for a succeeded native run in the
exhausted state, Retry re-arms the coordinator instead of creating a
provider retry. It writes a `coalesced` `task_retry` receipt bound to
the same run with strategy `finalize_result` (an existing strategy
value), joins any unadmitted Retry intent to it, and logs
`issue.retry_requested` with `strategy: "finalize_result"`. The
idempotency key still returns the same receipt on replay. A later click
with a new key, after an earlier saved-result Retry of the same run
(still finalizing, or applied), joins that Retry with another coalesced
`finalize_result` receipt and starts no provider work.
- `routes/issues.ts` (`POST /issues/:id/retry`): after the receipt
commits, it starts `refinalizeSavedNativeResult` for that run instead of
the provider Retry dispatch.
- `doc/execution-semantics.md`: documents the automatic delays and the
re-finalizing Retry.

## Verification

- `cd server && npx vitest run
src/__tests__/native-exhausted-finalization-retry.test.ts` (4 tests):
- Exhausted state reports `state: "failed"`, `canRetry: true`. Retry
re-arms the coordinator, writes a `finalize_result` receipt and an
`issue.retry_requested` activity row, and replays idempotently. A second
click with a new key while pending, and a third after commit, join the
same Retry; no provider Retry wake exists. While pending, the task shows
`working` / `finishing_recovery`. Re-finalization commits, and the task
shows resolved. The run count for the task stays 1, the coordinator
`attempt` is unchanged, the run stays `succeeded`, and no board card
stays active.
- Old-shape row (no `finalizationFailureCount`, `attempt: 3`, already
terminal): the same Retry works with no migration.
- Re-finalization that fails again: the coordinator goes to
`retryable_failure` with a fresh count of 1, then to `terminal_failure`
after the budget, and the task again shows `canRetry: true`. Nothing is
lost silently.
- Contention failures (failpoint `status_projection`): two automatic
delays (2 min, 10 min) with the task status unchanged, then the board
Retry, which commits with no new run.
- Red/green: with only the new module and test applied (finalizer,
presentation, task Retry, and route reverted), all 4 tests fail
(`canRetry` false; no automatic delay).
- `npx vitest run src/services/task-interruption-presentation.test.ts`
adds unit cases: the flag offers Retry; ordinary succeeded runs stay
resolved; ordinary failed runs keep `canRetry: true`; done tasks stay
resolved.
- Also passing: `native-finalization-retry-budget`,
`native-finalization-recovery`, `native-run-finalizer-telemetry`,
`task-interruption-query`, `interrupted-preparation-restore-retry`,
`native-result-commit-work`, `workspace-recovery-admission`,
`workspace-recovery-preparation-gates`,
`deferred-execution-receipt-work`.
- `npx tsc --noEmit -p server/tsconfig.json` passes.
- Not run: the full local suite (`pnpm verify` selects about 2,450 files
for these shared modules; CI covers it), and no live restart-chaos wave.

## Risks

- Previous-release story: coordinators saved by older builds in
`terminal_failure` / `native_finalization_retry_exhausted` qualify by
phase and code. The count is optional. Nothing is migrated. Older rows
do not get the automatic delays; they get the working Retry.
- Automatic delays add at most two extra finalization rounds of the same
saved result, only for contention causes, only for provider-succeeded
accepted results. During the delays the task keeps its prior status, as
it does during the normal 30 s retries. Supersession by a newer run is
still checked first on every attempt.
- The re-finalizing Retry applies the agent's saved result after a
person may have looked at the task in review. It uses the normal status
arbiter and CAS. Done and cancelled tasks, other assignees, and newer
runs refuse it.
- No change before `turn.start`: all new work is on the finalization,
presentation, and Retry paths.

DottaandClaude Opus 5.5 be0d100a8b fix(native): settle cleanup-gate refusals after a completed turn without a dead-end Retry (#20572)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Native runs execute a provider turn, then close the provider session
and prove it stopped
> - When close cannot prove that the old runner, provider and tools
stopped, the runner holds a cleanup gate
(`native_session_cleanup_quarantined`) that refuses the next session on
that task
> - A run finished its provider turn and saved its work. A server
restart had left one tool callback without a saved result, so close
could not prove the drain, and the gate refused the run's own same-run
recovery 30 seconds later
> - The task then showed "Couldn't finish this attempt" with a Retry
button, but the retry route refuses this error code with 409. The saved
error text told an operator to act
> - This pull request makes the task projection, the execution blocker,
the executor and the retry route agree, and replaces the operator text
with plain wording
> - The benefit is that finished work no longer looks like a failed
attempt, and the UI never offers a Retry that the server refuses

## Linked Issues or Issue Description

**What happened?**
A remote native run completed its provider turn and saved its comments
and documents. A server restart during the turn left one semantic tool
callback without a saved result. Session close then reported
`native_session_settlement_incomplete` (runner suspended, provider drain
unproven), and the runner kept an operator-required cleanup gate. The
same-run disposition recovery was refused at admission, and the run
ended `failed` with `native_session_cleanup_quarantined`.

**Expected behavior**
The task should show its real state (here, waiting on a child task). It
should not show a failure banner or a Retry that the server refuses. No
text should ask an administrator to act.

**Steps to reproduce**
1. Start a remote native run and restart the server while a tool
callback runs.
2. Let the resumed turn complete without a semantic result, so a
same-run recovery is scheduled.
3. Observe the refusal at admission, the "Couldn't finish this attempt"
banner, and a Retry that returns 409.

**Paperclip version or commit**
master at d0057ee384 (remote native runner, Daytona sandbox).

## What Changed

- Add `server/src/services/native-runtime/completed-turn-cleanup.ts`. It
holds one predicate for "a cleanup-gate refusal after this run's own
provider turn completed" and the plain user wording. It reads only the
saved `errorCode` and `runnerProfileJson.sessionCheckpoint`.
- `task-interruption-presentation.ts`: the projection never sets
`canRetry: true` for a cleanup-quarantined run, which matches
`routes/agents.ts` and `canRetryStoppedRun`. A quarantine after a
completed turn projects as `resolved` only while the task waits on
unresolved blocker tasks, so the task shows that wait. Without such a
wait, the missing task disposition stays visible. Other quarantined runs
show a plain settling message without Retry. The list query computes the
completed-turn fact in SQL.
- `native-session-executor.ts`: the refusal keeps its permanent, named
code, its hold and its ownership, and does not replay provider work. The
next action uses plain wording, and names the saved work after a
completed turn.
- `execution-blocker.ts`: show plain wording for this code instead of
the stored error text, also for rows that earlier releases saved.
- Runner error message and retry-route conflict message use plain
wording.
- `doc/execution-semantics.md`: document how the cleanup gate settles
and how the task shows it.

## Verification

- Red before the fix, green after:
- `server/src/services/task-interruption-presentation.test.ts` "native
cleanup quarantine presentation" (2 failed before: `canRetry: true`,
`state: failed`).
- `server/src/__tests__/task-interruption-query.test.ts` "reads a
quarantine saved after a completed turn as settled work" (real Postgres,
row in the previous release's saved shape; before: `state: failed,
canRetry: true`).
- `server/src/services/native-runtime/native-session-executor.test.ts`
"settles a cleanup refusal after a completed turn" (before: operator
next action and board ownership).
- `server/src/services/explicit-native-continuation.test.ts` "shows
plain wording for a cleanup refusal saved with the earlier operator
text" (before: stored operator text).
- The four files pass in full: 1851 tests.
- `tsc --noEmit` passes for `server` and `packages/paperclip-runner`.
- `pnpm verify` returns exit 2 (a global doc input changed), so required
CI supplies the broad coverage.
- No UI files changed, so token gates and UI tests do not apply.

## Risks

- Previous-release story: no persisted shape changes. Runs that earlier
releases quarantined carry forward. The new rules read existing fields,
so these runs show the new projection without a migration.
- The code stays permanent and named. No automatic provider replay is
added.
- A quarantine whose turn did not complete keeps its board-owned
recovery. Only its text and its Retry visibility change.
- The runner still keeps the in-process cleanup gate until environment
release proves the stop. Existing lease termination receipts
(`acknowledgeRemoteStop`) clear it. This PR does not change the runner
drain rule for a callback that a restart orphaned. That is a separate
follow-up.

Nicky LeachandPaperclip 2e3cbe57a4 fix(native): preserve parked Runners across controller restarts (#20586)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native execution parks a released sandbox Runner for a later turn.
> - The warm idle timer detaches Core and leaves Runner retention to the
host.
> - Controller shutdown instead stops recently parked Runners through
checkpoint cleanup.
> - This makes reuse depend on whether the idle timer fired before
shutdown.
> - This pull request uses the same detach operation for idle expiry and
shutdown.
> - The benefit is consistent Runner retention without a new retention
or recovery mechanism.

## Linked Issues or Issue Description

Fixes: #20012.
Related: #20005 unified cached and adopted process reuse. Closed #19975
included this shutdown change within a broader retention proposal.

## What Changed

- Detach confirmed released entries during controller shutdown. Keep
busy, unreleased, and close-marked entries on the existing cleanup path.
- Share the detach operation with idle expiry and cached-owner handoff.
- Record that a local handle has started detaching. Later cleanup cannot
fall back to stopping its Runner after a partial detach failure.
- Preserve explicit environment deletion, release proof, admission, and
process-reuse checks.
- Add Codex and Claude restart, detach-failure, and environment-deletion
regressions. Add real Runner adoption cases after the restart sweep,
including managed GitHub rebinding.
- Document the lifetime rule and make the shutdown warning cover both
detach and checkpoint failures.

## Verification

- Final source revision: `e4bb6ecbd7`. Local environment: macOS arm64,
Node 26.12.0.
- New controller-restart and detach-failure tests fail against unchanged
master: 4 expected failures. Old shutdown calls close or reports success
instead of reporting detach failure.
- Focused executor tests: 22 passed.
- Full native session executor suite: 1,328 passed.
- `cd server && node scripts/typecheck-layers.mjs`: passed all source
and test layers.
- `node scripts/check-module-boundaries.mjs` and `git diff --check`:
passed.
- Manual diff review and added-line credential/PII scan: passed.
- `cd server && node ../node_modules/vitest/vitest.mjs run
src/services/native-runtime/plugin-runner-release-resume.integration.test.ts
--bail=1 --reporter=verbose`: 14 passed on this revision. This includes
new Codex and Claude restart cases and managed GitHub rebinding.
- Failure history: an earlier concurrent run had 4 passes and 10
failures. Its first failure was the existing Claude cached case
exceeding 60 seconds. Later cases encountered a leftover prototype spy,
recursive calls, and startup timeouts. No source changed before the
passing full rerun. A clean worktree of unchanged master (`e01fe7f84a`)
passed all 11 original cases. The first timeout's exact cause remains
unknown; the later pass does not establish that cause.
- Standard Greptile review: 5/5 on
`e4bb6ecbd7bd965b5f56507d2c42c580e8a1d547`, with no actionable findings.
- `node scripts/local-verify.mjs --explain` returned exit 2 because the
execution-semantics document requires broad CI. Required CI will supply
broad typecheck, test, and build coverage.
- A hosted deployment and an actual controller process replacement have
not been run. The added integration cases exercise the shutdown sweep
and a new adopting transport against a real Runner.

## Risks

- SIGINT and SIGTERM preserve confirmed parked Runners, including
ordinary service stops. The host still owns eviction and retention.
- Detach failure retains a fenced local owner and reports failure. Core
does not infer permission to stop the Runner from that failure.
- Reuse remains conditional on current admission, process configuration,
and host availability.
- No persisted schema, checkpoint format, launch identity, or migration
changes. State from the previous release uses the existing adoption or
verified restore paths.

## Model Used

- OpenAI Codex, GPT-6, with reasoning, repository inspection, tool use,
and local test execution. The exact deployment identifier and
context-window size are not exposed in this session.

DottaandClaude Opus 5.5 96ab5e3d38 fix(recovery): read a retained Runner from its own allocation and continue unverifiable no-replay holds from the last save (#20567)
<!-- 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
> - Native warm runs on a remote sandbox continue a saved session in the
next run. The next run first reads the retained Runner lifecycle from
the sandbox.
> - #20346 abandons the workspace epoch of a run that died during
preparation. The next run then restores the last save into a new
directory of the same sandbox.
> - The retained-sandbox binding check required the old and the new
directory to be the same. The warm follow-up failed with
`native_controller_recovery_missing_evidence:retained_sandbox_binding`
before provider work.
> - The failed run's no-replay hold then refused its files with
`allocation_ownership_ambiguous`. The task stayed blocked. The text said
that Retry "succeeds only after Paperclip is updated", so no click could
help.
> - This pull request binds the Runner read to the directory that the
retained lease recorded, and lets the existing retained-source fallback
settle these holds from the last save.
> - The benefit is that a moved workspace continues its session, and a
hold that cannot be verified continues automatically instead of
dead-ending.

## Linked Issues or Issue Description

Refs #20346

**What happened?**
On staging, a warm native continuation ran about 10 minutes after a
deploy. The run before it died during preparation (database deadlock),
so its workspace epoch was abandoned. The continuation restored the last
save into a new allocation directory of the same Daytona sandbox. It
then failed with
`native_controller_recovery_missing_evidence:retained_sandbox_binding`,
because the retained lease of the committed source run recorded the old
directory. The failure recorded a no-replay hold
(`native_continuation_requires_reconciliation`, resolved with outcome
`blocked`). Workspace recovery refused the source with
`allocation_ownership_ambiguous`, because the sandbox's reusable-lease
chain had predecessors in another directory and a non-native
preparation-only run. The task stayed blocked with "Retry runs the check
again and succeeds only after Paperclip is updated."

**Expected behavior**
The continuation reads the retained Runner state from the directory
where that Runner wrote it, and continues. When retained files cannot be
verified, the task continues from the last committed save without a
person.

**Steps to reproduce**
1. Run a warm native session on a reusable remote sandbox and let it
commit.
2. Fail the next run during preparation, so that its epoch is abandoned
(#20346).
3. Start the next warm continuation. It restores the last save into a
new allocation directory and fails with `retained_sandbox_binding`.
4. See the hold refuse its source with `allocation_ownership_ambiguous`
and stay blocked.

**Paperclip version or commit**
Staging `c874cfa4dacc` (includes #20346).

## What Changed

- `assertNativeRetainedSandboxBinding` now returns the directory that
the retained lease recorded. It accepts a different target directory
only when both are canonical sibling allocations of the same execution
workspace under the sandbox's `.paperclip-workspaces` (`<workspaceId>`
or `<workspaceId>-<epoch>-<leaseId>`). Same sandbox (`providerLeaseId`),
environment, run, issue and committed owner are still required. Other
directories stay refused.
- `restoreRemoteSuspendedRunnerCheckpoint` reads the Runner state from
that recorded directory. A moved source must be suspended and settled. A
Runner left in the old allocation is never adopted live.
- The retained-source fallback (`continueFromLastSavedWorkspace`) and
its discovery now also cover the native no-replay hold
(`native_continuation_requires_reconciliation`, active or resolved with
outcome `blocked`, replay blocked for the same run). Rows saved by
earlier releases are discovered without migration.
- The fallback owns the Blocked status of such a hold only while the
recorded `nativeFailureBlock` status version still matches the task.
Otherwise it keeps the newer block and starts no continuation.
- The refusal text no longer says "succeeds only after Paperclip is
updated", and it promises no fallback.
- `doc/execution-semantics.md` describes both rules.

## Verification

- Red (unfixed code): `native-controller-recovery.integration.test.ts`
"binds a retained Runner read to the source's directory after the
workspace moved within the same sandbox" failed with
`native_controller_recovery_missing_evidence:retained_sandbox_binding`
at `native-controller-recovery.ts:145`, the staging error.
- Red (unfixed code): `workspace-recovery-fallback.test.ts` "continues a
resolved-but-blocked native no-replay hold from the last save,
discovered by the worker" failed: the worker found no due work for the
exact staging row. The newer-block safety case and the message case in
`system-recovery-state.test.ts` also failed.
- Provider boundary: a new test drives
`restoreRemoteSuspendedRunnerCheckpoint` through a sandbox runner that
refuses paths outside the sandbox workspace base. The suspended case
reads `runner-state.json` from the source directory, never the moved
root. The ready case is refused with `runner_not_settled` and caches
nothing.
- Green: `native-controller-recovery.integration.test.ts`,
`workspace-recovery-fallback.test.ts` and
`system-recovery-state.test.ts` pass (45 tests). The neighbouring suites
`workspace-recovery-retry-copyback`,
`workspace-recovery-preparation-gates` and
`workspace-recovery-stop-proof` pass (135 tests).
- Safety cases: another workspace, another parent, a non-canonical path
or name (`-0-`, trailing text), `/unrelated` and another sandbox stay
refused. A hold whose task moved to a newer Blocked decision keeps the
block and starts no continuation. Exactly one continuation is delivered.
Native replacement is denied for the abandoned source, so no second
executor starts.
- `npx tsc --noEmit -p server/tsconfig.json` passes. `pnpm verify`
returns exit 2 (a global doc input changed), so required CI supplies the
broad coverage.

## Risks

- Previous-release state: rows saved by earlier releases carry forward
without migration. The binding reads existing lease metadata. The
fallback discovers existing resolved-but-blocked holds by their existing
evidence fields.
- The binding now accepts a sibling allocation directory. The read still
binds to the exact sandbox, run, environment and committed owner, and it
reads only the source's recorded directory. A non-suspended Runner in a
moved allocation is refused, not adopted.
- The fallback abandons the unverified epoch and continues from the last
committed save with a fresh session. In the staging shape the run did no
provider work after it restored that save, so no work is lost.
Unverified files are attached to the task when they can be read, as
before.
- Not verified live: a real warm Codex resume after a moved allocation
on Daytona.

f4337bb5fb test(evals): land the chat catalog eval harness on master (#19614)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The chat-feature evals measure whether agents complete real chat
requests through the product
> - The chat catalog eval harness and its repairs live on the
`chat-eval/master-candidate` branch, not on master
> - Today's work made 139 of 242 chat evals pass in verified single-case
live runs. Each product fix landed on master as its own pull request
> - The eval-side changes (setups, graders, fault seams, evidence
capture) still exist only on the candidate
> - This pull request lands the harness on master. Master stays the
source of truth for product behavior
> - The benefit is one tree: evals run against master commits, and
product fixes reach the evals as soon as they merge

## Linked Issues or Issue Description

Refs #19441, Refs #19599, Refs #20270, Refs #20334, Refs #20342, Refs
#20344, Refs #20354, Refs #20360, Refs #20373, Refs #20382, Refs #20409

**What existing behavior does this improve?**
The chat catalog eval harness and the product it evaluates live on a
long-running branch outside master. Eval fixes do not reach master, so
master-based eval runs use old setups and graders.

**Subsystem affected**
`tests/runner-e2e` chat catalog harness, plus a small set of product
changes that exist only on the candidate.

**Proposed change**
Land the harness on master. Every product fix from this eval work
already merged to master as its own pull request. Conflicts keep
master's product behavior.

## What Changed

- Most of the diff (808 of 851 files) is under `tests/runner-e2e/`:
chat-catalog domains, scenarios, descriptors, the TestOps manifest,
private evidence tooling, and their tests.
- Graders now check saved state, setup literals and rendered or clicked
links. Many keyword and regex checks on free-form replies are removed.
Each changed grader has a bumped `oracleVersion` and calibration tests
(a valid reply, a reworded valid reply, and broken variants that must
fail).
- The shared link helper `hasLink` no longer treats a list link (for
example `/COM/issues?view=mine`) as a link to every task without a URL
key.
- Setup fixes build real state through supported product routes: routine
history, agent grants through the board grant route, budget holds with a
real cap, and a storage-layer archive fault for
`inbox-search.archive-partial-failure`.
- Browser boundary journeys (sign-in, chat-disabled, onboarding) now
write the standard pass evidence files.
- Retargeted cases, approved by the maintainer:
`agent-chat.chat-disabled` (Conference Room gate),
`agents.restore-instructions` (no saved instruction history),
`access.manage-membership` (member permission edits stay board-only).
- The private evidence trusted files (`manual-private-handoff.ts`,
`manual-private-retention.ts`, `manual-private-report-assets.ts`) are
byte-identical to master.
- Product files outside `tests/` (43 files, +1,328 −49) carry
candidate-only changes that master does not yet have. Most are tests.
The main code changes are in `request-human-input.ts`,
`heartbeat-run-summary.ts`, `native-completion-feedback.ts`,
`native-run-finalizer.ts`, `openapi.ts`, `secrets.ts` and
`IssueChatLongThreadPerf.tsx`.

## Verification

- `pnpm vitest run chat-catalog-domains chat-catalog-contract.test.ts
chat-catalog-consistency.test.ts unit-launcher.test.mjs
--testTimeout=180000` in `tests/runner-e2e`: 269 files pass, 3,550 tests
pass.
- `node --test chat-full-catalog-testops-manifest.test.mjs`: 10 pass.
- `node tests/runner-e2e/source-sdk-public-inputs.mjs <HEAD> --check`:
no change.
- `tsc` for `server` and `tests/runner-e2e`: clean.
- Live single-case verification: 139 of 242 cases passed on paid runs,
and a person read the saved evidence for each. These are single-case
runs, not one full-cohort run.

## Risks

- Large diff. Most of it is test-only, but the 43 non-test files change
product code paths. Review those files first.
- Some graders are now less strict on reply wording. A person must read
replies for meaning on those cases.
- 42 cases need disposable outside accounts (Notion, Slack, GitHub,
Daytona and others) and stay blocked. `access.invite-teammate` stays
failing until local agent isolation lands, because the runner's durable
state keeps a live invite token.
- The paid workflow compares the trusted private-evidence files with
master. They are unchanged, so this risk is low.

## Model Used

execution, in Claude Code. Subagents used the same model.

DottaandClaude Opus 5.5 fea4530a30 fix(recovery): retry a preparation killed by a restart in the uncharged lane (#20534)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When the control plane restarts, an interrupted run must continue on
its own. A user must not have to press Retry because a deploy or a crash
happened
> - A preparation that a restart stops before the provider starts spent
no provider work. It is retried in the uncharged
`interrupted_preparation` lane (12 retries), not the charged
`transient_failure` lane (2 retries)
> - #20496 made that work for a graceful drain (SIGTERM). A hard kill
(SIGKILL) during workspace preparation still landed in the charged lane
> - Two killed preparations in one chain then spent the failure budget,
and the next interruption could not continue: the task needed a manual
Retry
> - This pull request lets restart recovery hand a killed preparation to
the uncharged lane once the killed controller is proven gone
> - The benefit is that a task survives any number of restarts during
workspace preparation (up to the crash-loop cap) without a Retry click

## Linked Issues or Issue Description

**Subsystem affected**
Heartbeat restart recovery: the process-loss reaper in
`server/src/services/heartbeat/recovery.ts`.

**Problem or motivation**
The restart-chaos harness on Daytona with `--storage s3
--storage-trigger snapshot-download` (seed 603, task t02, a codex C1
follow-up) kills the server while a workspace snapshot downloads. On
builds that contain #20496, two replays still ended in
`R3:retry_needed`. The run chain in replay
`w-20261110T061107-s603-replay-t02-1794309789008`:

1. K1 SIGKILL during preparation: `process_lost`, then "Scheduled
bounded retry 1/2 … transient_failure".
2. K2 drain during preparation: `interrupted_preparation` 1 (the #20496
path, correct).
3. K4 SIGKILL during preparation: `process_lost`, then "Scheduled
bounded retry 2/2 … transient_failure".
4. K2 drain during preparation: the failure budget was spent
(`failureRetries` 2), so the hold could not continue. The harness had to
click Retry.

**Root cause**
The reaper does record the no-provider-work certificate
(`executionRecovery: { kind: "bootstrap", providerWorkStarted: false }`)
for a preparing run from another boot. But before it fails the run,
`revokeExpiredLegacyControllerWithState` swaps in a random boot id with
a 60 s lease, a tombstone that no controller holds.
`scheduleBoundedRetryForRun` then asks `isInterruptedNativePreparation`,
whose `preparerMayStillUnwind` check sees that live lease and says the
old preparer may still be unwinding. The lane falls back to
`transient_failure` and charges the failure budget. Every killed
preparation is charged, whether or not its controller is provably gone.

**Proposed solution**
When the reaper has already proven the old controller's recorded process
gone (`legacyControllerGone`, the shared owner prover that #20496 also
uses) and the revoked state shows the run was still preparing with no
process recorded (`restartInterruptedBeforeDispatch`), expire that
tombstone lease in the same `process_lost` write. The lane decision then
sees an expired lease and applies its existing checks (no coordinator,
result or execution events; leases released with stop receipts;
workspace repair when needed). Any evidence of provider work, or a
controller that cannot be proven gone, keeps today's charged behaviour.

**Alternatives considered**
- Revoking with an already expired lease: the 60 s revocation lease
fences other servers while this pass fails the run, so the expiry
belongs in the terminal write.
- Teaching `preparerMayStillUnwind` to ignore unstamped leases: that
would also skip the wait for a lease of a live controller saved by an
older release.

## What Changed

- `server/src/services/heartbeat/recovery.ts`: the `process_lost` write
sets `controllerLeaseExpiresAt` to now when
`restartInterruptedBeforeDispatch && legacyControllerGone`.
- `server/src/__tests__/heartbeat-process-recovery.test.ts`:
- New: a chain whose preparation is killed twice (controllers proven
gone) and then drained. Each kill schedules `interrupted_preparation`
(attempts 1 and 2, `failureRetries` 0), and after the drain the restart
settlement schedules `interrupted_preparation` 3 without a Retry.
- New old-saved/new-resumed case: a preparing run saved by an older
release without a controller process stamp keeps the charged
`transient_failure` lane.
- `doc/execution-semantics.md`: one additive sentence saying the lane
also covers a hard kill once the killed controller is proven gone.

## Verification

- Red/green: `npx vitest run
src/__tests__/heartbeat-process-recovery.test.ts -t "killed twice"`
fails on master (the first kill schedules `transient_failure`) and
passes with the fix.
- Related suites pass: `heartbeat-process-recovery`,
`interrupted-preparation-hold-settle`,
`execution-recovery-dead-controller`, `legacy-controller-lease` and
`ownership-reconciliation-report` (5 files, 521 tests).
- Live (Daytona, `--storage s3 --storage-trigger snapshot-download`,
replay of `w-20261110T061107-s603/t02` with K1/K2/K4/K2, image
`paperclip-daytona-runner@sha256:05a4a092…` whose runner content matches
this branch): running; the result will be posted as a comment.

## Risks

- Low. The change applies only when the shared owner prover returns
`gone` for the exact recorded controller and the run was still preparing
with no process recorded. The lease's boot id stays the random
revocation id, so the old controller can still never renew it. Old rows
without a controller stamp keep today's behaviour.
- Previous-release story (upgrade-safe-run-state): no persisted shape
changes. A run saved mid-preparation by an older release has no
`controllerProcess` stamp, cannot be proven gone, and keeps the charged
lane (covered by the new old-saved test). Retries an older release
already scheduled in the charged lane keep their counters.

DottaandClaude ca472d543a fix(runner): settle a saved governed wait whose shutdown drain left sequence gaps (#20494)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native agent run can ask the board a question and park on that
saved (governed) wait
> - After the question is saved, the runner interrupts the provider and
drains its usage and terminal for a bounded time
> - The drain keeps only usage, the terminal and cancellation facts of
the parked turn. It discards every other numbered provider event
> - If the control plane restarts before the drain settles, recovery
replays the saved journal. That replay required strictly contiguous
`sourceSeq`, so the discarded events made a valid saved wait look like
the wrong conversation
> - This pull request accepts a gap after the saved trigger only when
every event after the gap is a drain-retained fact of the same turn.
Identity checks do not change
> - The benefit is that the asking run settles its saved wait after a
restart instead of recording a failure

## Linked Issues or Issue Description

**What happened?**
Restart-chaos wave `w-20261110T063253-s208`, tasks t02 (Codex Q1, PV2:
provider terminal dropped) and t03 (Codex Q1, PV1: provider terminal
held), each with K1 (`kill -9` of the control plane about 3-4 s after
the fault). The question, the board answer and the final brief were all
correct. But the asking run was recorded `failed:
native_session_interrupted`, and the grader failed
`T:asking_run_settled`.

**Cause**
The run log of the asking run shows `failureDetail.message:
native_governed_wait_replay_mismatch`. It is thrown at
`packages/paperclip-runner/src/native-session-runtime.ts:2344` (master).
The persisted runner events of the asking run have `sourceSeq` 33..40
and then 43 (t02), and 41, 42 and then 45 (t03). The two missing numbers
are events that the accounting drain (`consumeTurn` →
`settleDurableResult`, around line 1206 on master) read and discarded,
because they are not usage, a terminal or a cancellation fact. Runs
without a restart have the same gap (for example
`w-20261110T032350-s201/t01`: 34, then 37). Those runs settle without
replay, so the gap was not seen before. With a held or dropped terminal
and a kill before the shutdown settlement receipt, recovery must replay.
Its strict contiguity check then fails on a gap that the runner made
itself.

**Expected behavior**
The question was saved before the provider was interrupted. Recovery
must settle that same saved wait, as #20336 does after verified
shutdown. Recovery must not start a new model turn.

**Related**
Refs #20336 (settle saved handoffs after verified shutdown). Not related
in cause or code: #20477, #20482, #20483.

## What Changed

- `isGovernedDrainRetainedEvent` (new, in `native-session-runtime.ts`)
names the facts that the governed-wait drain persists: usage, the turn
terminal, the interrupt acknowledgement, cancelled or expired runtime
requests, and a failed or cancelled `run.terminal`, all for the parked
turn. The drain now uses it in place of the same inline condition. Drain
behavior does not change.
- Governed-wait recovery replay accepts a `sourceSeq` gap only when:
- the trigger is the first replayed event (a gap before it still fails),
  - sequence numbers strictly increase,
- every event after the first gap is a drain-retained fact of the
trigger's turn.
- The run, normalized session and source instance identity checks do not
change. Any mismatch still fails with
`native_governed_wait_replay_mismatch`.
- `doc/execution-semantics.md`: the governed-wait text said that
shutdown keeps a contiguous journal. It now describes the gaps and the
replay rule.

Note for the sibling Claude/ACPX `turn.cancel` work: this change touches
`settleDurableResult` only in the drain filter line (same condition,
shared helper). It does not change cancel, the drain timeout or
`settleCancelledTurn`.

## Verification

- Red/green:
`packages/paperclip-runner/src/native-session-runtime.test.ts`
- `settles a saved governed wait whose drain left sequence gaps before a
restart (terminal-after-restart)`
- `settles a saved governed wait whose drain left sequence gaps before a
restart (late-terminal-saved)`

The first run uses the real drain. It discards two numbered events, so
the history is trigger, acknowledgement, then usage with a gap. The
stream then ends without a terminal, as with PV1/PV2 plus K1. On master,
recovery rejects with `native_governed_wait_replay_mismatch` (the live
error). With this change, recovery settles the saved wait as yielded. It
does not call `resolveGovernedWait` again. It starts no second turn. The
terminal is appended once. When the terminal arrived late and is already
saved, recovery does not cancel the provider again. A further recovery
of the settled checkpoint does not submit or settle again.
- Fail closed: `keeps rejecting an unproven governed-wait replay with a
sequence gap: …` covers a gap before the trigger, a foreign run, a
foreign session, a foreign source instance, usage of another turn, a
non-accounting event after a gap, and an accounting event followed by a
non-accounting event.
- `cd packages/paperclip-runner && npx vitest run
src/native-session-runtime.test.ts`: 261 passed. `npx tsc --noEmit -p
.`: clean.
- `cd server && npx vitest run
src/services/native-runtime/native-session-executor.test.ts -t
governed`: 12 passed.
- `pnpm verify` returned exit 2 (test file outside resolved graphs).
Required CI supplies the broad coverage.
- Live restart-chaos wave: see the comment below with the wave id and
result.

## Risks

- Low. The rule loosens only the sequence check, and only after the
saved trigger, and only for facts that the drain itself retains and that
carry no work authority. Identity checks stay strict. A non-accounting
event after a gap still fails closed.
- No change to the normal start path or turn startup (fast-turn rule).
- No schema, protocol or env change. The pack `contractDigest` and
provider `commandDigest` do not change. No Daytona image rebuild is
necessary.

## Model Used

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

DottaandPaperclip b09f17fbfd fix(agents): repair queued setup through task connection cards (#20361)
## Thinking Path

> - Paperclip manages AI agents doing work for people.
> - Agent verification must finish before an accepted task can start.
> - A missing AI account default can prevent verification before a
provider starts.
> - Lifecycle policy treated that owned configuration refusal as a
temporary failure and retried each minute.
> - The accepted turn remained Queued without explaining the
prerequisite.
> - Park account configuration failures and reuse the task's existing
inline connection card.
> - Successful repair rechecks verification and releases the original
queued turn under its original authority.

## Linked Issues or Issue Description

**What happened?** An OpenCode agent selected the responsible user's
OpenRouter default, but that default did not exist. Verification retried
unchanged configuration indefinitely and its accepted task stayed
Queued.

**Expected behavior:** Preserve accepted work, explain the setup
prerequisite, and let the appropriate person repair it using the
existing task connection UI. Completion must verify the agent before
starting the same queued turn. Genuine pause, approval and access gates
remain effective.

**Reproduction:** Create an OpenCode Runner agent with a
responsible-user OpenRouter binding and no personal default; assign a
task while verification is pending. The base retries verification and
shows an unexplained queue.

Related: #18702 handles pending task connection recovery after account
repair. This PR handles the earlier agent-verification boundary. #20330
addresses a separate Codex governed-wait timeout and is already merged.

## What Changed

- Share owned account-selection failure evidence through a pure library
contract. Lifecycle policy parks those configuration failures with
fixed, redacted guidance; temporary infrastructure errors retain their
retries.
- Batch setup-state reads for unstarted queued turns. Distinguish manual
repair from automatic setup retries and preserve Stop, started/history
state and lifecycle holds.
- Reuse the existing `connection_intent` card, account selection and
completion APIs. Its controller-only `agentSetup` marker accepts only
never-started legacy turns; runtime tokens still require a running run.
- Address the card to the lifecycle verifier's account owner, preserving
the task's execution principal and private-task visibility. Attach
missing cards on admission, verification, startup and full recovery,
including retained retries and continuations. Repeated delivery and
publication remain bounded. A new queued turn supersedes the setup card
of a stopped turn; generic connection cards retain cross-run reuse.
- Recheck lifecycle verification after usable-account completion, then
release the existing turn through the normal readiness path. Preserve
decline, Stop, reassignment and changed setup-owner gates. Fence an
in-flight verification failure from overwriting a repair; add no
provider wake or recurring worker.
- Park owned account refusals during resume as well as initial
verification. Bind setup cards to the lifecycle operation, settle
obsolete deliveries, and keep explicit Retry guidance accurate.
- Reuse the router’s existing lifecycle pin for setup repair without
rerouting the task, advancing the pool cursor, or replacing its saved
binding. Legacy direct-account cards remain readable.
- Hide the incorrect Resume banner during setup, retaining genuine
manual/budget pause controls. Document the execution and retry contract.

## Verification

- Red: eight original behavior assertions failed on the base, including
the real selector's retry decision and the real batched queue
projection. Six owned selection cases failed classification.
Temporary-error presentation, different task/verifier users, retained
retry/continuation recovery and the setup Resume banner also have
failing-before/passing-after regressions.
- Green: 430 affected backend, lifecycle, shared-contract and UI tests
passed before the final review corrections. Subsequent focused runs
cover one inline card, real account selection/completion, duplicate
delivery/publication, verification before readiness, unchanged run
authority, private tasks, no extra provider wake,
decline/Stop/reassignment, company isolation, invalid runtime tokens,
transient retries and redacted diagnostics.
- Final setup/card and generic connection-service suites: 49 tests
passed. The stopped-turn case failed before the correction, then passed
with real account completion, the stopped source remaining cancelled,
and the replacement source remaining queued.
- After rebase, all 129 focused assertions passed. The local queue
suite’s 88 execution assertions passed repeatedly, but its
database-fixture teardown exceeded both 30-second and 120-second hooks.
An isolated queue case completed, and the setup/connection suites fully
passed. The original queue test and cleanup remain unchanged; broad CI
supplies the full-suite result.
- Server/UI typechecks, module boundaries, token gates and diff checks
passed. `pnpm verify --explain` requested broad CI because the
execution-contract document changed; no redundant full local suite was
substituted.
- Real source acceptance: macOS arm64, Node 26.4.0, isolated embedded
PostgreSQL and local board identity. Created an OpenCode/OpenRouter
agent and task through the API with no default. Admission retained one
unstarted turn and produced the existing inline Connect OpenRouter card.
The browser opened its credential form and closed it without entering
credentials. The same card/run persisted after server restart and
reload, with the setup label and no incorrect Resume. The browser also
reproduced Stop followed by a new queued turn retaining the stale card
on the prior head. On `12f609c98372fd1e50644028db75cfcc8deb210d`,
startup superseded the stale card and retained the same replacement
turn, with the original turn still cancelled and no provider execution.
- The earlier CI case-search failure also reproduces on exact base
`0e3fdebea8257bdff11573081c76b306f12db230` without this PR. Its repair
is now in master via #20371; this branch is rebased onto it and contains
no API-search changes.
- Staging's actual Runtime test returned “Connect an account and choose
your personal default” before provider startup. The original turn later
started independently on deployed code, then hit a separate
workspace-export failure. Automatic file recovery subsequently marked
that run successful; its task remains Blocked and the trial’s useful
output is unverified. This PR is not deployed; provider authentication
through its card and downstream publication remain unverified. No
account, credential, default, permission or binding was changed during
diagnosis.
- Previous revision review: Greptile 5/5 on
`12f609c98372fd1e50644028db75cfcc8deb210d`, with all four inline
findings addressed and resolved. [Full CI
passed](https://github.com/paperclipai/paperclip/actions/runs/42713494508)
on that revision: 59 successful checks, one neutral check and three
intentional skips, with no pending or failed checks.

- Latest revision `976bcae993805a8a2222395bbff9394f6791b424`: resume,
router and Retry-copy regressions failed before repair. Green: 92
lifecycle/setup/shared tests, 83 setup/generic-connection/router tests,
and 137 UI/shared tests. Server/UI typechecks, module boundaries and
token gates passed. [Full CI
passed](https://github.com/paperclipai/paperclip/actions/runs/42720731137)
on this exact revision: 59 successful checks and three intentional
skips, with no pending or failed checks. Greptile reviewed this head at
5/5; all six review findings are addressed and resolved. Real Stop/retry
acceptance retained the same replacement turn and current-operation card
through two actual server restarts, with no provider execution.

## Risks

- Known account configuration failures now require repair or explicit
Retry. Temporary failures keep automatic retries; accepted work and
authority remain intact.
- The projection adds one company-scoped batch read only for unstarted
queued turns. Card attachment examines at most 100 active candidates and
adds no timer, worker, schema or migration.
- The optional stored setup-card marker requires an aware reader during
rollback. No run/session/checkpoint identity format changes. Setup
presentation grants no access and cannot bypass verification or other
gates.

## Model Used

- OpenAI GPT-6 (Codex), with reasoning, tool use, code editing and test
execution. The exact serving model identifier and context-window size
are not exposed in this session.

Nicky LeachandPaperclip 2550f399d9 fix(lifecycle): align stop proof for pre-dispatch resource waits (#20384)
## Thinking Path

> - Paperclip manages AI agents and controls when their work can run.
> - An agent pause waits until every earlier run has stopped.
> - Recovery already treats verified workspace and AI-capacity waits as
pre-dispatch outcomes.
> - The stop proof did not accept those same receipts. Historical waits
could keep an agent pausing forever.
> - This pull request shares the resource-wait classification and the
existing execution-event check.
> - The benefit is consistent stop evidence without a new lifecycle
command, database backfill, or host-boot assumption.

## Linked Issues or Issue Description

Refs #18147 and #17718.

This fixes the verified resource-wait case of #18147. It does not
certify ambiguous historical runs that have no positive non-execution
evidence.

An agent can have an old cancelled legacy run with `errorCode:
workspace_busy`, `executionStage: preparing`, and `executionRecovery: {
kind: workspace_wait, providerWorkStarted: false }`. No process, native
coordinator, or retained resource exists. Recovery recognizes this as a
resource wait, but pause previously required a stop acknowledgment from
an executor that never started.

### Credit and related work

Thanks to @br1an-c0des (#17692) and @crownlayerapp (#15383) for the
focused preparation and shared-admission analysis, @lucasweismann-ai
(#18072) for the durable dispatch-evidence and race analysis, and
@Pdesengrini (#18905) for the cancellation-receipt and process-identity
guard cases. We reviewed these alternatives before implementing this
smaller change. No contributor commits were cherry-picked.

The design uses receipts already written by core. It does not adopt a
reboot-time bypass, a new adapter-entry journal, or a pause-abort route.
#17236 and #20037 address the separate cost of history reads.

## What Changed

- Add one shared classifier for matching workspace and AI-capacity wait
receipts. Use it in legacy recovery and cancellation stop proof.
- Reuse the existing dispatch-event predicate instead of maintaining
another event list.
- Retain checks for native execution references, unresolved workspace
obligations, controller leases, and resource cleanup. A live controller
or cleanup still in flight cannot pass the proof.
- Add a focused PostgreSQL suite. It drives the real pause worker with
historical wait records and checks Retry eligibility against the same
evidence.
- Document the contract. No schema, API, UI, dependency, or scheduling
change is required.

## Verification

Source checkout on macOS arm64, Node 26.12.0, isolated local PostgreSQL
18, synthetic data only.

```sh
node node_modules/vitest/vitest.mjs run --root server \
  src/modules/agent-lifecycle/__tests__/resource-wait-stop.test.ts \
  src/services/legacy-execution-recovery.test.ts
```

- 61 tests passed across these two files.
- All eight positive regressions failed on unchanged master. The fix
restores them.
- After rebasing onto current master, the 61 focused tests passed again.
Another 53 selected tests passed in
`explicit-native-continuation.test.ts` with `-t 'pre-dispatch review
wait|unclaimed workspace retry|historical native preparation'`. The
other 361 cases in that file were not run.
- Guard cases cover wrong/missing receipts, dispatch events, process
identity, native ownership, live controller leases, workspace recovery,
cleanup in flight, unreceipted remote resources, and an unknown
historical HTTP dispatch.
- A remote lease passes only after its exact termination receipt is
stored.
- Secret/PII diff scan and `git diff --check` passed.
- Standard Greptile reviewed commit
`201a61d2bb63290ca9b9b9d524e6c6715a872310`: [5/5 with no actionable
findings](https://github.com/paperclipai/paperclip/pull/20384#issuecomment-6753165178).
No review threads are unresolved.
- Local testing is limited to affected cases. GitHub CI owns broad
typecheck, build, and test coverage.

Verification setup failures remain accounted for: worktree preflight
could not complete because Cargo is unavailable; the first bundled
PostgreSQL run failed because its macOS binary lacks a shared library.
The focused tests passed on a separate, temporary local PostgreSQL 18
cluster. An early local server typecheck could not resolve the unbuilt
Runner package; it is not claimed as a pass.

## Risks

- Stop proof now accepts existing positive resource-wait receipts.
Missing PIDs, terminal status, elapsed time, and a different boot ID
remain insufficient.
- The receipt must match its error code. The runtime must remain
unresolved, with a preparation or settled stage and no conflicting
native or workspace references.
- The shared cancellation proof is also used by explicit continuation
and Retry. Those paths keep their existing user-intent, ownership,
pause, budget, and authorization gates. A stop proof does not itself
start another run.
- Runs that lack usable evidence remain held. This PR does not claim to
repair every run shape reported on #18147.
- No migration or live data edit is needed. No hosted deployment is
included.

## Model Used

OpenAI GPT-6 through Codex, with repository inspection, code execution,
PostgreSQL regression tests, and GitHub tools. The exact serving
revision, context window, and internal thinking configuration are not
exposed in this session.

DottaandPaperclip 3cc1032f6a fix: deliver saved answers to dependency-blocked tasks (#20363)
## Thinking Path

> - Paperclip lets people direct agent work through tasks and structured
answers.
> - Dependencies stop task execution until prerequisite work finishes.
> - A person must still be able to answer or redirect the assignee of a
blocked task.
> - Ordinary comments already get a bounded answer/triage turn. A saved
question response has no comment ID, so the same gates reject it.
> - Later dispatch also requires an active task and tries to check it
out. That conflicts with bounded interaction on a blocked task.
> - This pull request verifies the stored human response at each gate
and keeps the turn in bounded interaction mode.
> - The assignee can receive the answer without starting dependency work
or removing its blockers.

## Linked Issues or Issue Description

Refs #19923. That change covers dependency waits and comment retries.
This change covers stored interaction responses that have no comment ID.

**What happened?**

A parent task waits on a parked child. The assignee asked a setup
question. After a person answers, the response stays queued. Sending
that saved response is refused as `issue_dependencies_blocked`. Ordinary
new messages can reach the same assignee.

Passing admission alone is insufficient. The dispatch status check
rejects a blocked task, and automatic checkout then tries to start work
whose prerequisites are unfinished.

**Expected behavior**

Deliver the stored human answer or confirmation to its requesting
assignee as a bounded answer/triage turn. Keep the task blocked and keep
its dependency relationships. Preserve current-owner, pause, approval,
budget, recovery, and execution gates.

**Steps to reproduce**

1. Assign a parent task and make a backlog child block it.
2. Save a question on the parent and answer it as a person.
3. Dispatch its resolved-interaction wake, or send the saved answer from
the task queue.
4. Observe that the answer does not reach the provider while an ordinary
comment can run in answer/triage mode.

**Paperclip version or commit**

Reproduced on master at `653ab8b18f76`. This branch is rebased onto
master at `0e3fdebea8`.

## What Changed

- Verify the stored response by company, task, requesting agent, status,
kind, human resolver, and resolution time. A context flag alone is
insufficient.
- Allow a verified response through dependency admission and claim in
the existing bounded interaction mode.
- Recheck that response during scheduled retry promotion and final
provider dispatch.
- Keep bounded responses from checking out the blocked task or setting
it to `in_progress`, including when the last blocker finishes during
preparation.
- Preserve continuation classification through workspace and AI-account
resource waits, so the final response and owner checks still run.
- Correct the task-case API summary so the existing `case for task`
discovery regression passes on the first search page. This fixes a
pre-existing failure exposed by full CI, without changing search ranking
or assertions.
- Ignore obsolete Retry notices after newer conversation work, without
acknowledging saved input or changing execution authority.
- Document the response contract. Add real PostgreSQL and
assembled-heartbeat regressions.

## Verification

- Final commit `ba4b337cf1bb0236b7c0a742665b222ee894ff51`: [required CI
passed, attempt
2](https://github.com/paperclipai/paperclip/actions/runs/42706363120/attempts/2),
including typecheck, production build, server/chat tests, Runner checks,
and all 8 browser shards. PR status: 59 passing checks and 3 normal
skips.
- Red: answered questions and accepted/rejected confirmations return no
admitted run before the fix. All three new positive cases fail at the
dependency gate. A resource-wait retry also reproduces as refused before
its gate is fixed.
- Green: at delivery revision `9375a603e4`, focused heartbeat
integration and classification passed 14 tests; retry scheduling and
dispatch safety passed 241 tests. These use real PostgreSQL and
controlled adapter and resource-availability boundaries. The wider
initial dependency, native-continuation, and queue suites also passed
before the final refinements.
- Negative cases keep pending, missing, wrong-task, and agent-resolved
responses blocked. Changing the response proof immediately before
dispatch cancels the run without calling the provider. Policy controls
retain the current assignee, task status, and pending approval checks.
- Positive cases execute once, leave the parent blocked, preserve the
dependency edge, and leave the child in backlog with no child execution.
The same saved response survives a resource wait; removing its human
proof refuses promotion.
- The resource-wait provider-boundary and blocker-completion regressions
also failed before their fixes. All 14 focused integration and
classifier cases passed at delivery revision `9375a603e4`, including a
changed response during retry preparation.
- Red: a retained Retry for an older run makes a newer successful
conversation display as failed. Green: all 78 database-backed query and
interruption-presentation tests pass, including a later real failure and
independent queued input controls.
- Server layered typecheck and module-boundary checks passed at
`11992aad0c7fbaf13e7548d71ee633560bd8bb6f`, before the one-line API
summary correction. That CI passed build, typecheck and every browser
shard, but exposed the pre-existing case-search assertion and a
report-assets test timeout. Final-head CI passed as linked above.
- Fresh Greptile review is 5/5 on final commit
`ba4b337cf1bb0236b7c0a742665b222ee894ff51`, with no unresolved threads.
- The existing API discovery suite reproduced its first-page assertion
before the summary correction; all 3 cases pass afterward. The timed-out
report-assets privacy test passed locally in isolation and the full
support job passed on the final-head rerun. Runner shutdowns interrupted
the first attempt; affected jobs were rerun once without code changes. A
separate onboarding timeout also passed on that rerun.
- `pnpm verify --explain` requests broad CI because the execution
contract is a global input. The final CI run supplied that coverage.
- Separately recovered the reported staging conversation through an
ordinary message and the existing steering control. The agent
acknowledged the message and the saved-answer queue drained. The fresh
Notebook action subsequently succeeded. This was on the previously
deployed revision; it does not claim this code is deployed.

## Risks

- This changes admission and dispatch. Each gate checks the persisted
response; no caller-supplied marker grants the exception.
- The bounded turn does not check out the task, resolve a dependency, or
approve another action. Existing pause, ownership, budget, approval, and
stopped-execution controls still apply.
- Each additional lookup is one primary-key read and runs only for a
response on a dependency-blocked path. There is no new polling worker.
- No migration is required. Older queued contexts get the exception only
when their stored human response still verifies. No prior run or action
is replayed by this change.
- This PR does not roll out the code to staging.

## Model Used

OpenAI Codex, GPT-6 family, with repository tools, code execution, and
browser inspection. The runtime does not expose the exact model ID,
context-window limit, or reasoning-mode label; those values are not
asserted.

DottaandPaperclip c67909cb0f fix: keep tool approvals valid through OAuth refresh and delayed review (#20340)
## Thinking Path

> - Paperclip lets people manage agent work and approve app actions.
> - An approval must bind the action that the person reviewed.
> - OAuth access tokens can expire while that person is away.
> - The old target snapshot treated each token refresh as a new
authorization. It also imposed a one-hour review deadline.
> - This pull request separates token renewal from authorization
identity and keeps the human decision durable.
> - Current access, the reviewed arguments, meaningful target changes,
task closure, and execution receipts still control dispatch.
> - People can approve later without repeating a decision after routine
connection maintenance.

## Linked Issues or Issue Description

**What happened?**

A pending app action returned `approved_tool_target_changed` after its
OAuth tokens refreshed. The tool and connection settings were unchanged.
The same card also expired after one hour. A sign-in problem could
discard an accepted decision before provider dispatch.

**Expected behavior**

The original card remains reviewable after routine OAuth refresh and a
server restart. A later approval runs the exact reviewed action once. A
connection repair preserves the decision while Paperclip verifies the
same authorization. Meaningful changes require a new review.

**Steps to reproduce**

1. Connect an OAuth MCP app and configure an action to require approval.
2. Request the action, then refresh its access and refresh tokens before
approving.
3. Approve the original card. Before this change, it returns HTTP 409
even when the authorization is unchanged.
4. Wait more than one hour. Before this change, the card expires without
a task-specific deadline.

**Paperclip version or commit**

Reproduced from master at `76254ead2229`. The final branch is rebased
onto current master.

## What Changed

- Add versioned approval target comparison. New snapshots bind
credential identity epochs, consent, permissions, ownership, connection
configuration, tool contracts, and credential references. Authenticated
OAuth refresh preserves identity. Manual credential replacement does
not.
- Remove the implicit one-hour deadline from ordinary app action
reviews. Keep explicit deadlines and terminal-task expiry. Synchronize
the nullable interaction deadline in shared contracts and UI.
- Keep accepted, undispatched actions when sign-in is required. Show a
saved-approval repair state. Resume on committed connection changes
after target and access revalidation, without an idle retry loop.
- Preserve the existing execution claim, result receipt, and
uncertain-outcome no-replay rules.
- Explain meaningful target changes without inviting the person to retry
the stale card.
- Add a production task-thread Storybook example and document
compatibility and recovery behavior.

## Verification

- Red: production-refresher invalid-grant handling and formal-approval
withdrawal during a sign-in wait also reproduced as failing regressions
before their fixes.
- Red: before implementation, the local OAuth HTTP fixture failed for
both public and confidential clients with `approved_tool_target_changed`
after token refresh.
- Green: the extended fixture passes for public and confidential clients
with personal and shared grants. It covers actual local HTTP token
exchanges, multiple refreshes, a rebuilt gateway, an ended originating
run, approval after 25 hours, duplicate approval, preserved sharing
arguments, sign-in waiting, and event-driven repair. The gateways use
the production OAuth refresher; an invalid refresh preserves the
accepted decision before provider dispatch. Omitted-scope responses
cover equivalent scope-reporting changes. The provider is an isolated
local fixture, not a deployed Notebook service.
- Negative controls refuse changed consent, scopes, tool definition,
destination, and manual credential replacement before provider
execution.
- Existing gateway service, connected-tool acceptance, secret owner,
secret service, unsigned-review queue, and connection-health suites
passed. Explicit-deadline fixtures still prove expiry behavior,
including deadlines on accepted sign-in waits. A withdrawn formal
approval cancels a waiting action before connection recovery.
- Approval card, task-chat, error-copy and target-comparison tests
passed. Server and UI typechecks passed. Token gates and Storybook
catalog checks passed.
- Inspected the new saved-approval repair card in local Storybook using
the production task thread. It shows a reconnect link and no second
approval button or false running state.
- `pnpm verify --explain` returned exit 2 and requested broad CI
coverage. [Full
CI](https://github.com/paperclipai/paperclip/actions/runs/42677855507)
passed on `eb4f1c7caa9ee6e802c314ffc5eadec475a5de0c`, including build,
typecheck/release registry, general and serialized tests, and all eight
browser shards.
- Greptile reviewed the same final head at 5/5. Both findings from the
first review are fixed and their threads resolved; no open follow-ups
remain.

## Risks

- No database migration is needed. The new comparison reuses the vault
identity epoch. Only authenticated OAuth refresh code can preserve that
epoch; HTTP credential-write schemas cannot select that behavior.
- Earlier signed requests keep their original exact-version checks and
saved deadlines. Already-expired cards are not revived. A historical
card whose credentials already changed needs a fresh review.
- A new consent, account, permission set, destination, or manually
replaced credential must not inherit the old authorization. Reconnection
continues automatically only when revalidation proves the same saved
authorization.
- The interaction enrichment now permits a null deadline. Existing
string deadlines remain valid. The web client and shared validator
change together.
- This PR does not deploy to staging or perform a live Notebook
publication.

## Model Used

OpenAI Codex, GPT-6 family, with repository tools, code execution, and
browser inspection. The runtime does not expose the exact model ID,
context-window limit, or reasoning-mode label; those values are not

DottaandPaperclip 0e325e8d52 fix(runner): settle saved handoffs after verified shutdown (#20336)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - An agent can save a question or approval handoff before its provider
stops.
> - A missing provider terminal notification does not prove that the
saved work failed.
> - Runner already verifies provider exit, event drain, tool settlement
and suspension.
> - This change uses that proof to settle the same saved handoff.
> - Unproven shutdown holds continuation and explains that the work is
saved.
> - Recovery must never repeat the completed work or allow overlapping
execution.

## Linked Issues or Issue Description

Refs #20330. That PR extends the Codex terminal drain window. This
change handles the separate case where no terminal arrives but the owned
shutdown can prove stopped execution.

**What happened?**

A native run saved a human handoff, accepted cancellation, and later
stopped its provider. The missing terminal notification still made the
attempt fail and show “Couldn’t finish this attempt.”

**Expected behavior**

Keep the saved handoff. Accept its yielded result after either an
authoritative provider terminal or verified shutdown of the exact
execution. If shutdown remains uncertain, retain the handoff and explain
the hold without offering a duplicate Retry.

**Steps to reproduce**

Save a governed wait, acknowledge interruption, and omit the provider
terminal. The new regression uses the real Runner binary and a
controlled Codex process. The old runtime rejects the handoff instead of
asking the existing shutdown owner to settle it.

**Deployment mode**

Native Runner with Codex. Local verification used macOS arm64 and Node
26.4.0. Hosted sandbox recovery has not been qualified.

## What Changed

- Add an optional driver shutdown-settlement operation. Runner returns
proof only after its existing stop, drain, tool settlement and
suspension barrier passes.
- Bind the receipt to the run, normalized session and turn. Persist it
with the saved wait and validate it during recovery.
- Complete the same yielded handoff after verified shutdown. Retire the
stopped session from warm reuse. Do not invent a provider terminal or
complete usage.
- Retain a named shutdown-pending condition under the existing bounded
same-run recovery policy. Preserve actual provider failures and
integrity failures.
- Show saved-work shutdown guidance in task and inbox presentation. Keep
genuine approvals authoritative and disable duplicate Retry.
- Document the completion and restart contract. The checkpoint field is
additive; older checkpoints retain the terminal-or-shutdown path.

## Verification

- Red: the new runtime regression failed against the original
implementation because verified shutdown was never requested. Server
presentation and error-classification regressions also failed before the
fix.
- Red: both inbox shutdown states showed generic text before the inbox
change.
- Green: Runner runtime, shutdown and harness-backend suites pass 301
tests. Tests cover missing terminals, failed stop proof, wrong identity,
cancellation, late proof, genuine provider failure, and restart after
receipt persistence. Recovery completes once without another model turn.
- Green: the native executor and task-presentation suites pass 1,371
tests. Execution projection, inbox and blocker presentation pass 125
tests. Two test-authoring mistakes were corrected: an integrity-error
text expectation and an assertion for a nonexistent projection field.
Their initial failures remain in local logs.
- Runner TypeScript and full server layered type checks pass. Token
gates and diff whitespace checks pass.
- Live provider acceptance: real Runner and Codex with gpt-6.1-sol, one
disposable local workspace, one tool call, and one deliberately dropped
terminal notification. The saved file, bound settlement receipt, one
accepted yielded result, one provider turn, confirmed provider exit and
suspended Runner all passed. The tool handler and persistence port were
controlled. This does not claim a full server or hosted journey.
- The full browser question-and-answer cell stopped before execution
because OPENAI_API_KEY was absent. No model work ran in that attempt.
Hosted sandbox recovery and the full browser continuation journey remain
unverified.
- `pnpm verify` returned exit 2 because the execution-spec change
requires broad CI. Required CI will supply that coverage; a full local
repository suite was not repeated.

- Review correction in `8553da244e`: a failed trailing-event write could
hide a provider failure. A new regression reproduced red, then passed
after all ordinary drain errors retained the named pending condition. No
settlement receipt or result can be accepted after that error. The live
missing-terminal check passed again on the corrected runtime.
- The real PostgreSQL control-plane regression and three existing
governed-wait controls pass. The new case persists one accepted yielded
result, a bound shutdown receipt, and the original pending human
question without a provider terminal.
- First CI revision `7c2cb9b1`: test-program typecheck found a missing
`PrpEvent` annotation in the new fixture. The annotation is fixed and
the Runner test-program typecheck passes. Runner support also timed out
in the unchanged `registered roots remain protected even when equal to
genuine public static bytes` case after 30 seconds. One unchanged local
diagnostic passed in 3.69 seconds overall. The hosted timeout cause
remains unknown; no timeout, fixture, or assertion was weakened.
[Original failed support
job](https://github.com/paperclipai/paperclip/actions/runs/42670851821/job/129346900133).

- Rebased onto the merged #20330 and current recovery changes. The
combined branch passes 1,402 executor/presentation tests. Both prompt
and 18-second provider terminals still pass. A warm session with no
terminal passes after the full 30-second drain and verified
stop/suspension. Its initial overly broad assertion rejected a
nonterminal turn event; the corrected assertion rejects every terminal
type. The rebased CI gate was cancelled before any runner or step
started; its cause is unconfirmed and it supplies no validation credit.
Final revision `b49ec5a144` starts fresh CI and review.

- Final-head CI attempt 1 failed before creating jobs. GitHub reports an
internal server error (correlation
`2c576b07-b67f-4179-a69f-74f7d99cd926`), followed by empty
runner-selection outputs for the aggregate jobs. One unchanged-commit
retry was requested; the initial admission failure remains recorded. [CI
run](https://github.com/paperclipai/paperclip/actions/runs/42673159868).

- **Current blocker:** final head
`b49ec5a144e94e41e96e2508a79bd9aec91fe45a` has a fresh 5/5 Greptile
review and zero unresolved threads, but required CI is not complete.
GitHub reports an active [Actions and Checks API
incident](https://www.githubstatus.com/incidents/tp8cghg7tlc4). Attempt
2 ran only part of the full selected graph. Build, canary, Rust, sandbox
providers, admitted browser shards and other completed test jobs passed.
The E2E aggregate correctly failed because `policy` and `e2e_shards` had
`abandoned` results. Server shard 5/12 received a runner shutdown signal
at 18:36:55 UTC and its test step was cancelled; its job still reports
in progress. The shutdown cause is not established. The separate review
workflow had the same pre-execution internal-error class and passed one
bounded retry. No further retry was submitted during the incident.
Resume with the missing/cancelled coverage after GitHub recovers; do not
count the absent typecheck, Runner or support jobs as passes. [Failed
coverage
gate](https://github.com/paperclipai/paperclip/actions/runs/42673159868/job/129354318236),
[interrupted server
shard](https://github.com/paperclipai/paperclip/actions/runs/42673159868/job/129350854174).

## Risks

- A missing terminal can use one additional bounded shutdown interval.
Unknown shutdown still blocks continuation.
- Provider terminal and usage accounting keep their separate meaning.
The receipt proves stopped execution and settled tool outcomes, not
model success.
- Recovery rejects a foreign receipt, a later turn, an active turn with
a settled receipt, and an actual failed provider terminal.
- There is no database migration. Older checkpoint shapes remain
readable. Drivers without this optional proof retain a named pending
state.
- This PR does not deploy the fix or repair an existing hosted task.

## Model Used

OpenAI Codex, GPT-6 family, with reasoning, repository tools and local
code execution. The exact serving model ID and context window are not
exposed in this session. Live test inference used gpt-6.1-sol.

DottaandClaude Opus 5.5 f56b097fbd fix(recovery): move stranded legacy subtasks off a parent's held workspace (#20314)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - Agents split work into subtasks. Since #19860, every subtask gets
its own execution workspace from the project base, and a subtask that an
older release bound to its parent's workspace moves to its own workspace
on its next admission
> - Some legacy subtasks never get a next admission. Another task held
the shared workspace with unsaved files, so their runs failed setup
before any provider work. Stranded-work recovery then blocked them and
handed them to the board
> - On staging, a parent and two of its children stayed blocked for four
days this way. The children could have run in their own workspace at any
time
> - This pull request makes the scheduled recovery-action sweep move
such a child to its own workspace and continue it, with no person
> - The benefit is that a legacy subtask never stays blocked on a
workspace that it should not share, and the parent keeps its own
workspace

## Linked Issues or Issue Description

Refs #19860 (subtasks get their own workspace; legacy children move at
admission)
Refs #20295 (the held workspace's exhausted save now settles
automatically)
Refs #20273 (stall wakes wait while a workspace hold refuses a run)

**What happened?**
A parent task and three children shared the parent's remote workspace,
because an older release created the children before #19860. One child's
ended run held the workspace with unsaved files. The other two children
were woken, but each run failed setup with "The workspace still has an
unfinished writer or save operation." (`setup_failed`,
`executionRecovery.kind=bootstrap`, `providerWorkStarted=false`).
Stranded-work recovery then set each child to Blocked with a board-owned
escalation (`board_escalation_no_takeover_v1`) that asked a board
operator to retry. The #19860 move happens only at the next admission,
and a blocked child gets no admission.

**Expected behavior**
A subtask that failed only because of a legacy shared-workspace binding
continues in its own workspace from the project base automatically. The
parent and the shared workspace stay unchanged.

**Steps to reproduce**
1. With a release before #19860, create a parent task and children that
share its remote workspace.
2. Let one child's run end with unsaved files whose save is not settled.
3. Wake another child. Its run fails setup on the workspace hold, and
stranded-work recovery blocks it with a board escalation.
4. See that the blocked child is never moved to its own workspace and
never runs again.

**Root cause**
`server/src/services/execution-workspaces.ts`
(`releaseAncestorWorkspaceBindingAtAdmission`) moves a legacy child only
when a run of the child is admitted.
`server/src/services/recovery/service.ts`
(`reconcileStrandedAssignedIssues`) ignores Blocked tasks, so nothing
admits a child that a setup failure on the shared hold blocked.

## What Changed

- `server/src/services/execution-workspaces.ts`: extract the binding
release into `releaseAncestorWorkspaceBinding(tx, …)`, which runs inside
the caller's transaction. Admission uses it unchanged (same guards: no
other running run of the task, no unsettled workspace recovery, only a
relative's workspace).
- New `server/src/services/recovery/legacy-workspace-rehome.ts`
(`rehomeStrandedLegacyWorkspaceTasks`). It selects a board-owned
stranded escalation whose latest run failed setup on the workspace
writer hold before any provider work, for a Blocked task bound to a
relative's workspace. In one transaction it releases the binding,
resolves the escalation with the outcome
`legacy_shared_workspace_rehomed`, sets the task to `todo`, records a
pending wake (`legacyWorkspaceRehome.wake: "pending"`), and records
`issue.legacy_workspace_rehomed` system activity. After commit it wakes
the assignee once (`issue_recovery_action_restored`, with a fresh
session) and marks the wake `delivered` only when a run is created. A
wake lost to a crash, refused (`null`), or failed stays pending and
backs off (5 minutes, doubling, at most an hour); the pass returns the
earliest owed wake as its retry deadline, so the recovery worker
schedules it. Candidates are paged by action id.
- Guards: the Blocked status must come from that escalation (set after
the failed run, and no status decision at or after the block), the
shared dependency-readiness rule must allow work (cancelled blockers and
done blockers that still save files keep it blocked), the failed run
must belong to the current assignee, and the binding release must be
allowed. Otherwise nothing changes.
- `reconcileActiveRecoveryActions` (the company-scoped sweep that the
scheduled issue-recovery worker runs for each company with an active
recovery action) runs this pass first. `recoveryActionSweepCondition()`
also selects a company whose moved task still owes its wake.
- `doc/execution-semantics.md`: documents the move and what a moved
child sees.

### What a moved child sees

A fresh workspace from the project base, exactly like a new top-level
task in the project. It does not get the parent's changes. It does not
get its own earlier files from the shared workspace either, because
nothing of its work ran there (its runs failed setup before any provider
work). The child that still holds the shared workspace with unsaved
files is not moved by this change: its save recovery owns the hold
(#20295 settles it automatically), its files stay in the shared
workspace and in that recovery's saved-work receipts, and it moves on
its first admission after that recovery settles (the #19860 rule).

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

- **Migrated, no schema change.** The change reads escalations and task
bindings that older releases saved, and it changes only the task's
binding row, the task status, and the escalation. It does not change
saved run identity (native execution input, leases, checkpoints,
sessions). The regression test seeds the exact staging shape (Nov 4–5
evidence fields, `retryReason: workspace_busy`, `latestRunErrorCode:
setup_failed`).
- **Mid-run deploy.** A child with a running run or an unsettled
workspace recovery is not moved (the same guards as the admission
release).

## Verification

- Red (the move disabled), `npx vitest run
src/__tests__/legacy-workspace-rehome.test.ts`: 1 failed, 2 passed. The
staging-shape case failed because the stranded child stayed Blocked and
bound to the parent's workspace.
- Green: 8 of 8 pass. All cases run the scheduled path: the company is
selected by `recoveryActionSweepCondition()` and the pass is
`recoveryService(...).reconcileActiveRecoveryActions({ companyId })`
with the real heartbeat wake.
- Staging shape: a parent and 3 children share the parent's workspace.
One child holds it with a dirty writer run. Two children are blocked by
board escalations after setup failed on that hold. After the
stranded-work sweep, both children are unbound from the shared
workspace, their escalations are resolved by the system with text that
asks no person to act, and each child is woken exactly once with a fresh
session. Each child runs once through the real heartbeat path outside
the shared workspace and completes. The parent and the writer child keep
their bindings, the shared workspace row is unchanged, and nothing runs
for them. A later pass changes nothing.
- A move whose wake was lost to a crash: the scheduled worker still
selects the company, delivers the wake once, and the child runs and
completes.
- A refused wake (`null`) or a thrown enqueue stays pending, backs off,
does not hold up other wakes, is reported to the worker as the next
deadline, and keeps the company selected after a restart; once accepted,
it settles.
- Thirty rejected escalations do not hide a later eligible one (paging).
- A child with a cancelled blocker stays blocked with its board
escalation.
- A child whose last status decision came before the block moves; one
decided after the block stays blocked.
- A stranded child whose setup failed for another reason stays blocked
with its board escalation.
- A task bound to the workspace it created (the parent) is never moved.
- Related suites pass: `subtask-workspace-independence`,
`heartbeat-workspace-busy`, `heartbeat-remote-workspace-busy`,
`heartbeat-held-comment-wake`, `recovery-deadline-acceptance`,
`heartbeat-retry-scheduling`, `task-workspace-binding` (278 tests), and
after the review changes `issue-blocker-stall-wakeups`,
`issue-recovery-deadlines`, `issue-recovery-work-lifecycle`,
`recovery-durable-wait-projection`, `owner-gone-attestation` (124 tests
with the two workspace suites).
- `pnpm verify`: exit 2 ("broader verification required", because
`doc/execution-semantics.md` is a global CI input). Required CI supplies
the broad coverage.
- `npx tsc --noEmit -p server/tsconfig.json`: passes.

## Risks

- The pass changes a Blocked task to `todo` only under narrow guards,
and only for a task bound to a relative's workspace whose last run
failed setup on that workspace's writer hold. A Blocked status from
another decision, or an unresolved blocker, keeps the task blocked.
- The moved child starts again from the project base. This is the
product rule for subtasks. Nothing of its own work is dropped, because
its runs failed before any provider work.
- The pass runs inside the existing active recovery action sweep and
selects at most 25 escalations and 25 pending wakes per pass.

DottaandPaperclip 76254ead22 fix(runner): allow Codex interruption to settle governed waits (#20330)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - A native run must stop provider work before it waits for a human
response.
> - The Codex transport allows 30 seconds for a control command.
> - The governed-wait loop used its 15-second default for Codex.
> - A valid interruption terminal at 18 seconds therefore failed the
run.
> - This change gives Codex the existing 30-second terminal drain
allowance.
> - The run still fails if it cannot prove that the provider turn ended.

## Linked Issues or Issue Description

**What happened?** A Codex run can save a human wait, accept an
interruption, and fail before the provider sends its terminal. Its saved
wait remains intact, but normal finalization does not occur.

**Expected behavior:** Allow terminal delivery through the transport's
bounded command window. Keep missing-terminal cases closed.

**Steps to reproduce:** Run the new protocol regression against the old
backend. The real Runner binary uses a controlled Codex process that
delays its interruption terminal for 18 seconds. The run fails at the
15-second drain deadline. The same process passes with this change.

**Paperclip version or commit:** Reproduced against `1b7fe33432`.

**Deployment mode:** Local test of the native Runner path. The incident
was observed in a hosted sandbox.

**Installation method:** Source checkout.

**Operating system:** macOS arm64 for local verification. Hosted
incident runtime was Linux.

**Additional context:** No matching repair was found. This addresses a
reproducible deadline mismatch. The hosted log ends terminal observation
at 15 seconds, so it cannot prove whether that provider would have
settled within 30 seconds. The approved local live-provider check
passed. This PR does not claim recovery of the hosted task.

## What Changed

- Give Codex a 30-second governed-wait terminal drain through the
existing backend option.
- Keep other providers and the caller's shorter execution bound
unchanged.
- Add real Runner protocol cases for prompt, delayed, and absent
terminal delivery. Check retained wait state and one provider turn.
- Document the bounded wait and terminal-proof requirement.

## Verification

- Red: the 18-second controlled-provider case failed with
`governed_wait_provider_terminal_unproven` on the old backend. The
prompt case passed.
- Green: 282 tests passed across the native runtime, harness backend,
and new Runner protocol suite, including a repeat on the rebased PR
revision. `pnpm verify --explain` returned exit 2 because the
execution-contract document requires broad CI; the [required CI
run](https://github.com/paperclipai/paperclip/actions/runs/42668235142)
passed on the final head. All 58 applicable checks passed; the three
skipped checks were the two unrelated Storybook jobs and the
selected-test planner replaced by broad coverage.
- The missing-terminal case still fails without `completeRun` or a
successful run terminal. The saved governed wait remains available. Only
one provider turn and one tool call occur.
- Existing runtime tests cover shorter deadlines, foreign or unproven
terminals, complete usage without a terminal, and checkpoint recovery
without another model turn.
- Live acceptance at `f3da2b87425d4fd45c649bfc98785c61f82abbe0`: real
Runner binary, Codex CLI 0.165.0, gpt-6.1-sol, Node 26.4.0, macOS arm64,
disposable local workspace. One `request_human_input` tool call returned
a pending interaction fixture. The real provider emitted
`turn.interrupted`; the controller accepted the yielded wait and its run
terminal. The check passed in 8.14 seconds. The tool callback and
persistence port were controlled; no hosted server permission or
Notebook publication claim is made.
- Initial local probe setup failed before model execution: first the
explicit launch lacked `app-server`, then it omitted the Runner
permission configuration. The successful check used the Runner's normal
launch arguments and isolated home with the approved existing account.
- Hosted sandbox acceptance and recovery remain unverified. The
18-second delayed shutdown is a controlled protocol regression; the live
model check proves normal shutdown, not that specific latency.

## Risks

- A Codex provider that never stops can occupy the settlement window for
up to 15 additional seconds. It still fails closed and is quarantined.
- No persisted schema, provider identity, permission, or recovery rule
changes. Previous-release checkpoints use the same format and existing
recovery checks.
- This change cannot fix a provider that never emits a terminal. It also
does not grant missing setup permissions or decide pending approvals.

## Model Used

OpenAI Codex, GPT-6 family. The exact serving model ID and context
window are not exposed in this session. Used reasoning, tool calls, code
edits, and local execution.

Dotta a3e7e63330 Guard Native recovery with process-space proof and explicit containment (#19813)
## Thinking Path

> - Paperclip manages agents and their work.
> - Recovery must preserve execution ownership and accepted results.
> - A saved PID proves nothing outside its recorded process namespace.
> - Uncertain unfinished work must stay held until its original owners
stop.
> - Operators need a source-bound containment action and a separate
ordinary Retry.
> - Accepted results must use the existing finalizer without another
provider turn.
> - This PR keeps those paths safe, recoverable, and quiet between real
obligations.

## Linked Issues or Issue Description

Refs: #19713

Refs: #19591

Recovery could use a local PID to release or replace a controller from
another process namespace. Connected-chat Retry also rejected successful
containment on a task in `todo`. The new containment action used a
broader permission than the existing owner-stop action. A later review
found that result-less guards also rejected the existing accepted-result
confirmation action.

## What Changed

- Record and verify the controller's kernel/PID namespace. Keep unknown
and foreign unfinished ownership held. Preserve independent durable stop
evidence and the existing remote lease fences.
- Use the shared accepted-result ownership reconciler. Bind settlement
to the observed lease token, generation, boot, PID, namespace and
process birth. Retain finalizer, cleanup, current-controller, live-owner
and remote exclusions.
- Share the remote-owner reader across recovery consumers. Scope runner
leases to the same company, task and run. Do not make local PID probes
for remote accepted-result ownership.
- Gate original-host containment on `runtime:confirm_owner_stop`. Bind
it to the current task, source, assignee, original expiry, lease and
Stop state. Audit separate controller/provider containment and reviewed
action outcomes.
- Keep containment separate from ordinary Retry. Use one canonical
committed receipt and the normal admission, budget, workspace and
lineage checks. Preserve the recorded external-action outcomes.
- Keep the controller-only confirmation actionable for both result-less
work and accepted results. Result-less work gets its next source-bound
attention in the same transaction. Accepted results keep their original
result and use normal shared settlement/finalization.
- Keep identity inspection quiet. Preserve the original foreign-owner
expiry and use the existing scoped finalizer in accepted-result recovery
controls.
- Update the recovery card, validators, execution projection, docs and
access maps. Reuse existing canonical columns; add no migration or
ownership backfill.

## Verification

Current publication head: `71ea76b568de09d6313d8992e803131d9d5c54f3`.

**The current fix has a causal red/green check.** On the test-only
revision, both foreign-local stopped/fenced controller cases failed
because recovery probed saved runner, process-group and provider PIDs in
this host's namespace. This measured the wrong probes; it did not run
duplicate providers. After the fix, the same two cases passed every
no-probe, no-claim, no-controller-stamp, no-stop-receipt and
unchanged-authority assertion. Three existing remote preparation, grace
and fenced-controller progress cases also passed. Total: **5 passed, 0
failed;170 filtered rows excluded**. All three normal affected App
TypeScript programs passed on this head (660,681 and428 roots).

The fix separates a controller wait from execution stop proof.
Independent live/grace evidence still schedules recovery. A
stopped/fenced foreign controller can pass this namespace guard only for
remote execution, which keeps its later checkpoint and never-launched
checks. Foreign local execution stays held before runner or provider PID
inspection.

Earlier source-scoped results remain evidence, not fresh executions on
the current head:

- On `c86dd741`, the complete failed-owner file passed **25/25**, with
no skips or filters. Empty scans wrote no controller stamps. Foreign
ownership kept its original expiry. Normal returned-claim settlement and
attention at the exact deadline passed.
- On `c86dd741`, **15 selected accepted-result/restart controls
passed**. The81 filtered rows are excluded. Both completion cases used
the existing scoped finalizer and kept their accepted result without
another provider turn.
- Trusted CI at synthetic merge `50d072a5` (actual master `1b7fe334`
plus `c86dd741`) passed the complete **17-case maintenance-server
file**. This includes the original90-real-second quiet observation and
two qualified hourly windows. The quiet case took118,918ms. The four
jobs that failed on the earlier publication all passed on that synthetic
merge.
- On `6243b32c`, the complete ownership-report file passed **29/29**.
Native NULL namespace stayed unprovable and generic compatibility
remained. Three selected recovery controls passed;170 filtered rows are
excluded.
- On `f81f2c3c`,356 business cases passed: whole ownership-route221,
recoveryUI70, owner-proof38 and controller-confirmation8; selected
accepted-result authority18; and one real connected-chat containment,
separate authorized Retry, useful Native result and downstream reply
case. The2,024 filtered rows are excluded. A separate earlier
accepted-result causal case kept the original result and completed after
restart without replay.

Normal Shared exports, App programs, UI typecheck, token gates and map
checks passed on their recorded revisions. Unchanged DB, adapter, Eval
and Runner inputs/outputs have explicit carry proofs. The clean normal
merge with fetched master `8fe524f7` preserves all31 exclusive owned
paths and14,827 unrelated master entries. The nine overlapping paths
were reviewed, including the upstream unidentified-run stop action.
Fresh CI must validate that actual merge composition.

PG cases used existing external PG17, fresh owned databases, pools at
most4, one worker and no SQL observer during cases. Registered clients
and recorded process groups closed. Independent final SQL audits found
zero campaign sessions before normal database cleanup. Original failing
fixtures remain retained.

Original failures are preserved. One new test first failed compilation
due to a missing getter import; an import-only correction passed its
full owning programs before the causal red/green check. A local quiet
attempt stopped in the normal prerequisite hook before any business case
and its collector rejected two normal build markers. The later17-case CI
pass establishes quiet recovery; it does not turn that failed local
collector into a pass. An earlier useful case passed before its private
cleanup collector failed on an owned read-only directory; normal cleanup
completed after all owners closed. Earlier runner-shutdown cancellation
and a separate private whole-suite failure remain unexplained.

Current-head checks are complete:57 success,1 neutral and3 skipped,
including the successful aggregate CI gate. The legacy status passed.
Greptile is5/5 and Ponytail gives an explicit5/5 Ship verdict for this
head. All seven review threads are resolved. Full recursive typecheck,
the full test suite and release build were not repeated locally. No
result here proves deployed suspension, a live provider or termination
on another host.

## Risks

- Unknown physical ownership can require an owner/admin action. A false
containment statement can be unsafe.
- New work, reassignment, Stop, renewed authority, accepted results or
pending cleanup can invalidate an action. The operator must refresh.
- Controller confirmation does not prove provider/tool containment.
Completed external actions must not be replayed.
- Generic legacy and child-process compatibility remains separate from
the strict Native controller policy.
- Existing saved state and canonical schema are preserved. Permanent
safety refusals remain held with their normal named recovery path.

## Model Used

OpenAI `gpt-6.1-sol` agents implemented and tested the changes with
reasoning, repository tools and code execution. A GPT-6-based Codex
managing agent reviewed and integrated them. The host does not expose
the manager's exact build or the context-window sizes.

DottaandClaude Opus 5.5 47dccbf3eb fix(recovery): re-prove an exhausted save's agent stop and free the workspace (#20295)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - When an agent run ends, Paperclip saves the files that the run
changed in its remote workspace. Until that save settles, the run holds
the workspace, so no other task can write it
> - When the save fails, a bounded system recovery proves that the agent
stopped (a provider stop receipt) and then saves the files again
> - If the stop cannot be proven before the 30-minute recovery window
ends, the recovery is exhausted with `agent_stop_unconfirmed`.
Exhaustion was terminal: Paperclip never proved the stop again, even
after the run ended and its sandbox had a stop receipt
> - The hold then stayed forever. On staging, a child task's save was
exhausted this way on Nov 5. Its parent and its two sibling tasks share
that workspace, and all of them stayed blocked for four days
> - This pull request re-arms such an exhausted save automatically, on a
bounded backoff, once the run is provably over. After the bounded
re-arms, the hold continues from the last save with the unsaved files
attached
> - The benefit is that a dirty workspace hold always settles without a
person, and no unsaved work is discarded silently

## Linked Issues or Issue Description

Refs #20273 (the stall sweep stops failing wakes against this kind of
hold)
Refs #20278 (a settled restore hold returns its warm sandbox)
Refs #19860 (subtasks get their own workspace)

**What happened?**
A child task's run wrote its remote workspace and failed to save it
(`native_workspace_sync_out_retry_exhausted`). The save recovery made
one attempt. That attempt failed with `agent_stop_unconfirmed`, and the
recovery window ended before a second attempt. The recovery became
`exhausted`. Ten minutes after the first attempt, the sandbox lease got
a provider stop receipt, so the agent was provably gone. But nothing
looked at the exhausted recovery again. The run kept the workspace's
writer hold. The parent task and every other task on that workspace
could not start ("The workspace still has an unfinished writer or save
operation."). The blocker told a person to press Retry.

**Expected behavior**
An unproven stop is a wait, not a refusal of the saved files. When the
run is over, recovery must prove the stop again and finish the save, so
the hold settles automatically. If the stop still cannot be proven,
Paperclip must keep the unsaved files and then release the hold. A
person must not need to act.

**Steps to reproduce**
1. Run a task in a remote (sandbox) workspace. Make its final save fail.
2. Keep the workspace recovery from proving the agent stop until its
30-minute window ends (for example, keep the finalization ownership
busy).
3. See that the recovery action is `exhausted` with
`agent_stop_unconfirmed`, and that it stays so after the lease gets a
stop receipt.
4. Wake another task bound to the same workspace. See that its setup
fails because the workspace is held.

**Root cause**
- `server/src/services/workspace-recovery.ts`
(`recoverRetainedWorkspace`): an `exhausted` state only goes to the
sibling settlement and to the retained-source fallback. The fallback
accepts only permanent source refusals (`isUnverifiableSourceFailure`).
Every other exhausted state is handed to the board and never attempted
again.
- `recheckStoppedWorkspaceRecovery` skips `exhausted` states, and it
only accepts acknowledged cancellations. A failed run whose lease got a
stop receipt later is never re-examined.
- `retainedWorkspaceCandidates(…, obligationsOnly)` and
`nextWorkspaceRecoveryAt` do not select exhausted
`agent_stop_unconfirmed` holds, so the recovery worker never wakes for
them.

## What Changed

- New `server/src/services/workspace-recovery-stop-proof.ts`
(`rearmExhaustedStopProof`). For an exhausted save whose last failure is
`agent_stop_unconfirmed` (`recheck_evidence`), it starts a new bounded
system recovery generation. It does this only when the source run is
provably over: the run is terminal, no local execution remains, and no
controller lease or finalizer lease is live. The new generation repeats
the strict stop proof (a provider stop receipt) and the save. It records
an `issue.workspace_recovery_rearmed` system activity.
- Re-arms are bounded: at most 4. The first is due at once. The next
ones are due 30 minutes, 2 hours and 8 hours after the previous re-arm.
The `stopProofRecovery` marker in the recovery action evidence records
the count and the next due time.
- `workspace-recovery-fallback-discovery.ts`: new discovery conditions
(`stopProofRearmPendingCondition`, `stopProofRearmDueAt`,
`stopProofRearmDueCondition`) and `retainedHoldFallbackEligible`.
`retainedWorkspaceCandidates` (worker pass) and
`nextWorkspaceRecoveryAt` use them, so the recovery worker wakes when a
re-arm is due.
- `workspace-recovery-fallback.ts`: when every re-arm is spent and the
stop is still unproven, the hold takes the existing retained-source
fallback. The unsaved files are attached to the task (unapplied, secrets
omitted), the unverified epoch is abandoned, and the task continues from
the last save.
- `system-recovery-state.ts`: the exhausted `agent_stop_unconfirmed`
text now says that Paperclip tries again automatically. It no longer
asks a person to press Retry. Retry stays available.
- Review follow-ups: the re-arm applies to every workspace recovery the
worker owns (restore and historical holds too). A due re-arm is
scheduled no earlier than the source run's controller or finalizer lease
expiry, so the worker is not woken every 15 seconds while a lease is
live. A fallback whose bounded checks are spent is reconsidered once
when an allocation of the source run changes, and
`settleStopOnlyCleanup` wakes the workspace recovery worker when it
records a stop receipt. The automatic-retry text is shown only while a
re-arm remains.
- `doc/execution-semantics.md`: documents the re-arm, its bounds, the
fallback, and the upgrade behavior.

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

- **Carried forward, no migration.** A hold exhausted by an older
release has no `stopProofRecovery` marker. The recovery worker treats it
as due at once and re-arms it on its first pass after deploy. The new
regression test saves the exact Nov 5 evidence shape (`attempts: 1`,
`retriesUsed: 0`, `state: exhausted`, no marker) and resumes it with the
new code.
- **Mid-run deploy.** A run that is still running, or whose controller
lease or finalizer lease is live, is not re-armed. The test covers a
live controller lease. The re-arm uses the same CAS (generation and
revision) and the same row locks as the other recovery writers, so an
old worker's late write cannot overwrite the new generation.
- **No new refusal codes.** No saved run identity changes. The re-arm
writes only recovery-action evidence.

## Verification

- Red (before the fix), `npx vitest run
src/services/workspace-recovery-stop-proof.test.ts`: 3 failed, 1 passed.
The staging-shape test failed because the worker did not wake
(`nextWorkspaceRecoveryAt` returned `null`) and the hold stayed. The
backoff and fallback tests failed for the same discovery gap.
- Green (after the fix): 4 of 4 pass.
- Staging shape: a parent and 3 children that share one remote
workspace. One child's save is exhausted with `agent_stop_unconfirmed`,
and its run ended days ago with a stop receipt. Before recovery, the
hold refuses the parent (`remoteWorkspaceHoldRefusesStart` is `true`).
The recovery worker discovers the hold, re-arms it, proves the stop,
saves the files and completes. The workspace is not dirty, it has a new
snapshot, and the hold is `free` for the parent. The action stays
system-owned and its text asks no person to act.
- A live controller lease keeps the hold. No re-arm happens and no lease
is resumed.
- A re-arm that is not yet due is not discovered. The worker's next wake
is in the future, and the text says that Paperclip tries again
automatically.
- After 4 re-arms, the hold continues from the last save. The unsaved
files are captured as a task attachment, and the hold is `free`.
- A live controller lease defers the worker's next wake to the lease
expiry, and the hold is not selected before it.
- A spent fallback is not selected, and a later lease change (a late
stop receipt) makes it selected again; the worker then settles it.
- `system-recovery-state.test.ts`: the automatic-retry text appears only
while a re-arm remains.
- Related suites, all pass: `src/services/workspace-recovery*`,
`src/services/remote-workspace*`,
`src/services/system-recovery-state.test.ts`,
`src/services/task-retry.test.ts`,
`src/__tests__/heartbeat-observed-workspace-preservation.test.ts` (34
files, 1510 tests), plus the stop-cleanup suites
(`environment-retained-orphan-sandbox`, `live-recovery-work`,
`retained-native-session-cleanup-work`,
`legacy-workspace-restore-recovery`, native workspace warm-reuse,
cancelled preservation, reconstruction and failed recovery; 11 files,
622 tests).
- `pnpm verify`: exit 2 ("broader verification required", because
`doc/execution-semantics.md` is a global CI input). The focused suites
above cover the change, and required CI supplies the broad coverage.
- `npx tsc --noEmit -p server/tsconfig.json`: passes.

## Risks

- A re-armed generation resumes the stopped sandbox to save its files.
This is the same physical path as a manual Retry. It runs only when the
source run is provably over.
- Re-arms are bounded (4) and spaced, so a stop that can never be proven
does not loop. After that, the existing retained-source fallback settles
the hold. If the retained files cannot be read, the fallback records
why. This is the same behavior as for a refused source.
- The parent's workspace receives the child's saved files, because the
child (bound by an older release) wrote that workspace. This is the
existing #19860 behavior: the files that a legacy child left in the
shared workspace stay there. #20314 moves the stranded legacy children
to their own workspace.

DottaandClaude Opus 5.5 fd2e7482c0 fix(runner): stop a lost runnerd's provider and tools from a durable lineage journal (#20270)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A local native run uses one runner daemon (`paperclip-runnerd`).
runnerd starts the provider (for example OpenCode), and the provider
starts tool processes
> - When runnerd dies in the middle of a tool call, the provider and its
tools are re-parented. The only record of that process tree was in
runnerd's memory
> - Close then cannot prove that those processes stopped. It quarantines
the session, and the next attempt stops with
`native_session_cleanup_quarantined`: "Automatic recovery stopped /
operator recovery required"
> - Restarts and runner loss are product failures. Interrupted work must
recover by itself, and it must never get two writers in one workspace
> - This pull request makes runnerd journal its process lineage to disk,
and makes close stop and prove gone every journalled process after
runnerd is lost
> - The benefit is that a killed runnerd leads to an automatic, safe
retry within the normal attempt budget, instead of an operator stop

## Linked Issues or Issue Description

Refs #20259 (runner loss classification and the lineage sampler panic).
Refs #20260 (automatic continuation of an inert cleanup quarantine).

**What happened?**
A chat eval killed only the owned local `runnerd` process (SIGKILL)
during an OpenCode tool call
(`chat-features.runner-opencode.local.recovery.retry-exhausted`,
`recovery.explain-stall` and `recovery.source-action`). Attempt 1
recorded `native_runner_process_exited` with "Retry scheduled 1/3".
Attempt 2 stopped with `native_session_cleanup_quarantined`. The task
was blocked with no owner, and the next action was operator recovery.

**Expected behavior**
After runnerd is lost, the product stops the provider and tool processes
that runnerd started, proves them gone, and continues the run within its
retry budget. When it cannot prove that, it keeps the fail-closed
quarantine.

**Steps to reproduce**
1. Start a local native OpenCode (or Codex) run.
2. Let the agent run a tool that leaves the provider's session (for
example `nohup job &`).
3. Send SIGKILL to the `runnerd` PID only.
4. Close rejects with `runner did not durably suspend before
checkpoint`, and the next attempt fails with
`native_session_cleanup_quarantined`.

**Paperclip version or commit**
master at 4c15eea770

## What Changed

- `process_lineage.rs`: runnerd journals each supervised process's
lineage to `<runner state>/process-lineage/lineage-<runnerd
pid>-<n>.json`. The journal holds the root, every member, and every
group and session a member leads, each with its start time. The first
record is written when the provider is spawned, before any tool can run.
Later records are written by the existing 50 ms sampler only when the
record changes. A teardown that proves the lineage gone removes the
journal.
- `process_lineage/journal.rs` (new module): the on-disk format, the
write rules and the reaper `reap_journals`. The reaper refuses when
runnerd never journalled (no writer marker) or when runnerd is still
alive. It restores each journal into the same `LineageState` rules,
sends TERM and then KILL only to processes whose PID and start time
still match, and reports `verified` only when none remain. A journal
that it cannot read refuses the proof.
- Unsampled escapes: each record stores `sampled_through`, the newest
process start that its read listed. The value is refreshed at most once
a second while the membership is unchanged. The reaper refuses
(`unattributed_orphan`) when a same-user orphan (parent PID 1) that is
in no journal started after that point. Such a process can be a tool
that started after the last read, so the reaper neither signals it nor
ignores it.
- A failed journal write removes the writer marker. Removal needs no
free space. After that, no reap can verify from a record that may be
missing a member.
- `paperclip-runnerd`: durable mode enables the journal before any
provider starts. A new `reap-lineage --state-dir --runner-pid` mode
prints the report and exits 0 only when verified.
- `runnerd-codex-transport.ts`: close samples whether runnerd exited
unsuspended before close sent any signal. In that case, for a runnerd
that this transport spawned on this host, it runs the reaper from the
same executable. A verified report ends the session as a crash stop with
its durable record intact. Recovery then continues the run. Any other
result keeps the existing `NativeSessionCloseUnrecoverableError`
quarantine. Launcher-owned (remote) and adopted runners do not use this
path.
- `runnerd-codex-transport.ts`: close does not queue a durable
`runner.suspend` for a runnerd that it already knows is lost. Before,
that suspend stayed pending in the saved control-plane state. A later
runnerd on the same root then failed at startup with `terminal command
result acknowledgement changed its durable identity`. The shared
suspension barrier is unchanged for remote and adopted runners.
- `runnerd-codex-transport.ts`: a runnerd that exits during close (for
example because its provider snapshot is unreadable) is not a loss. It
keeps the quarantine.
- `runnerd-codex-transport.ts`: `#runnerHasExited` treated a
signal-killed runnerd as alive, because `exitCode` is `null` and only
`signalCode` is set. Close then spent its whole deadline trying to
suspend a dead runner. It now checks `signalCode` too.
- `fake-codex-app-server`: `--spawn-escaped-tool-job <pidfile>` starts a
tool job in its own session at turn start.
- `doc/execution-semantics.md`: describes the journal, the reaper and
the fallback.

## Verification

- Rust, `cargo test -p paperclip-runner-core --lib process_lineage` (14
pass) and `process_supervisor` (20 pass). New cases:
- `reaping_refuses_an_orphan_born_after_the_last_sample`: a tool starts
after the last read, starts a new session and exits, and leaves a
non-leader orphan job. The reap refuses and does not signal the job. It
fails without the guard.
- `a_failed_journal_write_withdraws_the_writer_marker` and
`an_unchanged_record_is_rewritten_only_to_advance_sampled_through`.
- `reaping_stops_a_dead_runners_provider_and_its_escaped_tool_job`: a
real provider and a real `setsid` tool job, with a dead writer. The reap
stops both, proves them gone and retires the journal and marker.
- `reaping_refuses_without_a_marker_or_while_the_writer_lives` and
`reaping_refuses_an_unreadable_journal`.
- `a_journalled_record_restores_the_same_lineage`: after a round trip,
the restored record still finds a re-parented job and its later child,
and ignores an unrelated process.
- TypeScript, live with the real debug runnerd: `stops a lost runnerd's
provider and escaped tool job from its lineage journal`.
- `journal=true`: SIGKILL runnerd mid-turn. The escaped tool job
outlives runnerd. Close resolves, the job is gone, and the report is
`verified`. Before the fix, close rejected with `runner did not durably
suspend before checkpoint` and the job stayed alive.
- `journal=false` (an older runnerd with no journal): close still
rejects, and the job is not signalled.
- `runner-lineage-reap.test.ts`: a report from an older runnerd, a
malformed report, or an inconsistent `verified` report never counts as
proof.
- Turn-start cost: the journal adds one single-process read and one
small file write when runnerd spawns its provider (about 1.5 ms in a
macOS debug build), once for each runnerd. Nothing is added for each
turn.
- Paid runner E2E,
`chat-features.runner-opencode.local.recovery.retry-exhausted`, on the
eval branch with this fix (runs 42637596571 and 42644400434). Before the
fix (run 42615758956), attempt 2 stopped with
`native_session_cleanup_quarantined`. Now each of the three runnerd
kills records `native_runner_process_exited`. Attempts 1 and 2 are
`retryable_failure`, and attempt 3 is `terminal_failure` with cause
`native_session_retry_exhausted` (attempt 3 of 3). The reaper ran after
the first kill and verified. The cell still fails one eval setup check.
The check waits for an *active* exhausted recovery action, but
`execution-recovery-resolution.ts` settles that action as resolved and
blocks the task (`preserve_without_replay_v1`). That is a separate
grader decision, outside this PR.

## Risks

- Medium. The change only affects a close where runnerd already exited
without suspending and without a signal from close. Every other close is
unchanged.
- The reaper signals processes by PID. Each signal re-checks the PID's
start time first, and a group or session is used only while its leader
PID still names the recorded process (the same rules as the existing
in-process teardown).
- A crash stop leaves the durable root unsuspended. The coordinator
already scheduled a retry for `native_runner_process_exited`. That retry
now runs instead of failing on the quarantine. The paid E2E shows that
attempts 2 and 3 start on the same run.
- The escape guard can refuse when an unrelated same-user process
becomes an orphan in the window of about one second after the last read.
The fallback is today's quarantine. An orphan of a subreaper other than
init is not seen by the guard.
- The journal adds at most one small write each second for each runnerd
while processes start on the host. This happens on the background
sampler, not before turn start.
- Previous-release story: no database or saved-session schema change.
The journal is a new file in the runner state directory. A runnerd from
an older release writes no journal and has no `reap-lineage` mode. Its
loss keeps today's quarantine, and the existing board Retry and
stopped-session proofs still apply.

## Linked Issues or Issue Description

**What happened?**
A parent task was woken by `issue_blocker_stalled` twice every ten
minutes. Each run failed in setup (`setup_failed`,
`executionRecovery.kind=bootstrap`, `providerWorkStarted=false`) with
"The workspace still has an unfinished writer or save operation." The
parent's remote workspace was held by a child's ended writer run whose
save recovery was exhausted
(`native_workspace_sync_out_retry_exhausted`, last failure
`agent_stop_unconfirmed`). The child shared the parent's workspace
because an older release created it before subtasks got their own
workspace (#19860).

**Expected behavior**
A wake that cannot start because its workspace is held must not create a
failed run every time. It should wait until the hold settles. Automatic
retries must be bounded.

**Root cause**
- `server/src/services/heartbeat/workspace-preparation.ts` rethrows
`RemoteWorkspaceWriterActiveError` as a setup failure when the ended
writer is silent past `WORKSPACE_BUSY_HOLDER_STALE_AFTER_MS`
(documented, intended).
- `server/src/services/recovery/blocker-stall-wakeups.ts` retried every
non-delivered wake row (including `failed`) after
`REFUSED_WAKE_RETRY_MS` (10 minutes) with no backoff and no limit, and
it did not check whether the waiter could start at all.

## What Changed

- `remote-workspace-writer-hold.ts`: add
`remoteWorkspaceHoldRefusesStart`, the one rule for a hold that
reservation refuses outright (unattributed writer, or a writer silent
past the cutoff with no live owner fence).
- `workspace-preparation.ts`: use that rule instead of an inline copy,
so reservation and wake senders cannot drift.
- `blocker-stall-wakeups.ts`: before waking a waiter, check for proof
that its run would be refused. The proof is that the assignee's own
latest run on the task failed setup with the unfinished-writer error,
and the bound workspace hold still refuses a run. Then do not wake it;
count it as deferred and re-check at most hourly. A different assignee
(for example a controller-only agent that never uses the workspace), a
later run, or a settled hold lets the wake through. Reservation already
tried and failed the unchanged-writer release for that run, so the sweep
does not repeat that proof.
- `blocker-stall-wakeups.ts`: count failed runs that carry the stall
(the keyed wake's run and keyless resource-wait retries that keep its
context). Retry after 10, then 20 minutes, and stop after the third
failed run. Refusals (wake-on-demand off, agent paused) keep the
10-minute retry. A new stall (new recovery action) wakes again.
- `remote-workspace-writer-hold.ts` / `remote-workspaces.ts`: share the
unfinished-writer error text as one constant.
- `doc/execution-semantics.md`: document both rules.

## Verification

- Red before the fix
(`server/src/__tests__/issue-blocker-stall-wakeups.test.ts`): 3 new
tests failed. The held-workspace test got a delivered wake; the backoff
test got a third wake 11 minutes after the second failure.
- Green after the fix: `npx vitest run
src/__tests__/issue-blocker-stall-wakeups.test.ts` passes 22/22. Added
after review: a waiter with no refused run, or a reassigned waiter, is
still woken; failed resource-wait retries count toward the limit.
- The new tests use the staging shape: a legacy `shared_workspace`
remote workspace owned by the parent, a child bound to it, the child's
failed native writer run ended four days ago with
`native_workspace_sync_out_retry_exhausted`, a dirty authority, and the
child's board-owned exhausted recovery action. The parent's own earlier
run failed setup on the hold, as on staging. They also prove that a
writer inside the cutoff still gets its wake (the run parks in a
workspace wait), and that the wake is delivered once the hold settles.
- Related suites pass: `heartbeat-remote-workspace-busy.test.ts`,
`heartbeat-dependency-scheduling.test.ts`,
`native-cancelled-workspace-preservation.test.ts`,
`src/modules/run-dispatch`.
- `npx tsc --noEmit -p server` passes.
- `pnpm verify` exits 2 because `doc/execution-semantics.md` is a global
CI input; required CI supplies the broad coverage.

## Risks

- Low. No schema or persisted-shape change. Saved state from the
previous release (existing wake rows, existing workspace authority) is
read as-is: earlier `failed` stall wake rows count toward the new
three-run limit, which stops the current loop at once after deploy.
- A parent whose workspace stays held is not woken for the stall until
the hold settles. The stall is still listed on its page and the child's
recovery action stays with the board.
- Not fixed here: the exhausted save hold itself is never settled
automatically (`agent_stop_unconfirmed` exhaustion in workspace
recovery), and legacy children that still share a parent's workspace are
not moved. Both touch workspace recovery code that is under concurrent
change and are left for a follow-up.

DottaandClaude Opus 5.5 8525bb534c fix(chat): post a turn's answer when a card it did not create is pending (#20220)
## 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 thread can hold a pending card that the board addressed to
another person, for example a human-only confirmation for Riley.
> - When Alex asks the agent to act on that card, the agent correctly
gets `403 interaction_human_only` and writes a final answer that
explains the denial.
> - The shared answered rule (`conversationTurnAnswered()`, from #20179
and #20204) counted any pending human-only card in the thread as the
turn's own response. So the answer was suppressed, and the chat stayed
`active` with no reply.
> - This pull request limits that rule to cards that the turn's own run
created. Other cards still hold the task status.
> - The benefit is that the person always gets the turn's answer, unless
the turn itself asked a question with a card. Live completion and
restart recovery stay consistent.

## Linked Issues or Issue Description

Refs #20179, #20204 (the shared answered rule this PR corrects).

**What happened**

In an Agent Chat, the board created a pending `request_confirmation`
card with `resolverPolicy: human_only`, addressed to another user
(Riley). The card has no source run. Alex wrote "I approve Riley's
request." The agent tried to accept the card and got `403
interaction_human_only`. It then wrote a correct final answer: the card
needs Riley. The run succeeded with a `yielded` result and a
`response_wake` continuation. Run completion recorded
`presentationDecision: none`. No comment was created. The conversation
stayed `active`, so Alex never got a reply.

Cause: `conversationTurnAnswered()` reused the status-gate query
`pendingNativeInteraction()`. In conversation mode, that query excludes
another run's card only when it is an ordinary question or an `anyone`
confirmation. A human-only card addressed to someone else is kept. The
rule then treated that card as the card that "presents the turn",
although this run did not create it.

**Expected behavior**

A successful chat turn posts its final answer exactly once, and the
conversation moves to `waiting`. Only a pending question or confirmation
card that the turn's own run created presents the turn in place of its
prose. A card from an earlier turn, or one the board addressed to
another person, can hold the task status, but it does not suppress the
answer.

**Steps to reproduce**

1. Open an Agent Chat as Alex.
2. As the board, create a pending `request_confirmation` card in the
chat with `resolverPolicy: human_only` and `addresseeUserId` set to
another person.
3. Send "I approve Riley's request."
4. Let the agent try to accept the card, get `403
interaction_human_only`, and end its turn with a final answer.
5. See that no reply appears, `presentationDecision.commentAction` is
`none`, and `conversationState` stays `active`.

## What Changed

- `server/src/services/native-runtime/native-governance.ts`:
`conversationTurnAnswered()` now checks only pending cards whose
`sourceRunId` is the turn's run. `pendingNativeInteraction()` gets an
optional `createdByRun` filter for this. The status gate
(`pendingNativeGovernance()`) does not change, so another person's card
still holds the task.
- Both callers get the fix through the one shared rule
`conversationTurnPresentsAnswer()`: live run completion
(`run-completion.ts`) and background presentation recovery
(`recoverCommittedNativeChatResponse`).
- `server/src/services/heartbeat/run-completion.test.ts`: new live cases
"someone else's confirmation card" (board-created, human-only, addressed
to another user, no source run) and "earlier turn's question card"
(created by an earlier run of the same agent). Each case now also checks
that the conversation moves to `waiting`.
-
`server/src/services/native-runtime/agent-chat-response-recovery.test.ts`:
new restart case for the board-created card, plus a `waiting` check
after recovery.
- `doc/execution-semantics.md`: state that only the turn's own card
presents the turn.

## Verification

- Thesis: the reply is suppressed because the answered rule counts any
pending human-only card in the thread, not only this run's card. If this
is true, a turn with only a board-created card addressed to someone else
posts no comment on master, and restricting the rule to `sourceRunId =
runId` posts exactly one comment and settles the conversation to
`waiting`, with the own-card cases unchanged.
- Failing first: without the fix, the two new live cases failed
(`expected [] to deeply equal [answer]`). The new recovery case also
failed (no comment).
- After the fix:
- `cd server && npx vitest run
src/services/heartbeat/run-completion.test.ts -t "posts a waiting
conversation turn"`: 9 passed (includes the two own-card cases, which
still post nothing).
- `cd server && npx vitest run
src/services/native-runtime/agent-chat-response-recovery.test.ts`: 62
passed.
- Both suites use a real embedded PostgreSQL database.
- Turn start: no change. The rule runs only after the provider turn
ends.

## Risks

- Low. Only the presentation rule changes. The status gate, the
conversation settle rule (it already required `sourceRunId = run.id`)
and the external-chat path do not change.
- Behavior shift: a turn now posts its answer while another run's or the
board's card is pending. Before, the answer was lost. A card that the
turn itself created still presents the turn, as before.
- Previous-release state: no persisted shape change. A run that the
previous release already recorded as `none` keeps that decision.

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

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

## Linked Issues or Issue Description

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

**What happened**

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

**Expected behavior**

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

**Steps to reproduce**

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

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

**What happened?**

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

**Expected behavior**

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

**Steps to reproduce**

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

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

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

**What happened**

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

**Expected behavior**

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

**Steps to reproduce**

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

## What Changed

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

Other finish outcomes I checked:

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

## What Changed

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

## Verification

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

## Risks

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

## Model Used

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

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

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

## Linked Issues or Issue Description

Refs #20067, #20054

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

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

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

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

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

## What Changed

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

## Verification

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

## Risks

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

## Linked Issues or Issue Description

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

**What happened?**

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

**Expected behavior**

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

**Steps to reproduce**

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

**Paperclip version or commit**

`master` before this PR.

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

## What Changed

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

## Verification

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

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

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

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

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

Related: none found.

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

Refs #19720, #19747, #19856

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

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

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

## What Changed

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

## What Changed

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

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

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

## Verification

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

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

## Risks

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

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

hold blocks the task until the worker saves them from the retained
sandbox.

task. The check then refuses the source with

The only text left tells a person to inspect the run and its
environment.
> - The source check must stay strict. Recovery must still work without
a person.
> - This pull request adds an automatic fallback: the task continues
from its last committed workspace save, the unverified files are
attached to the task but never applied, and the unverified workspace
epoch is abandoned so its root is never reused.

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

## Linked Issues or Issue Description

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

**What happened?**

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

**Expected behavior**

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

**Steps to reproduce**

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

**Paperclip version or commit**

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

## What Changed

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

Safety:

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

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

## Verification

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

## Risks

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

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

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

## Linked Issues or Issue Description

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

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

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

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

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

## What Changed

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

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

## Verification

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

## Risks

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

## Model Used

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

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

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

## Linked Issues or Issue Description

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

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

Refs #19868, #19871, #19846

## What Changed

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

## Verification

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

## Risks

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

## Model Used

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