DottaandPaperclip 98d17da1e2 Fix native monitor dispatch and finalization recovery (#16975)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Native runs persist their results and workspace before they release
execution.
> - A task monitor must wait for that settlement before it starts the
next run.
> - The scheduler checked provider status but did not check unfinished
finalization.
> - A timer could dispatch too early, then its old finalizer could no
longer find the consumed schedule.
> - This pull request delays dispatch and reconciles prior delivery from
server records.
> - The task can continue without repeating the provider turn or
removing a newer run's ownership.

## Linked Issues or Issue Description

**What happened?**

A native run saved a yielded monitor result while workspace finalization
needed recovery. Its timer dispatched after the provider stopped. The
follow-up failed because the earlier run still held workspace recovery.
The old finalizer then retried `monitor_wait_authority_lost`
indefinitely.

**Expected behavior**

Timer dispatch waits for native finalization. If an older timer already
dispatched, the finalizer uses its saved scheduling receipt and admitted
successor to settle the old result. It preserves current task state and
ownership.

**Steps to reproduce**

1. Schedule a task monitor from a native run and save a yielded result.
2. Leave native finalization retryable after the provider reaches a
terminal state.
3. Let the monitor become due. Before this change, the scheduler
consumes it.
4. Restore workspace persistence and retry the old finalizer. Before
this change, the missing schedule leaves it retryable.

**Paperclip version or commit**

Reproduced against master `34be1b831bcaba070264ae8d214ceffe6a8f9eab`.

**Deployment mode**

Self-hosted server built from source, with PostgreSQL and the native
runner. Related recent recovery work: #16962 and #16963. No duplicate
repair found for this failure.

## What Changed

- Scheduled and manual monitor dispatch wait for unfinished native
finalization. If the monitor expires during workspace recovery, the
accepted result can settle into the persisted schedule, and the
scheduler then applies its existing expiry policy. New monitor-wait
results still require an unexpired, unexhausted schedule.
- A narrow reader joins the run's server-issued monitor receipt to its
durable wake and admitted successor.
- The finalizer and locked status commit verify that evidence and
preserve current task ownership. They do not create another wake.
- Monitor delivery participates in assessment identity, so recovery can
replace a prior error decision without violating the decision ledger's
uniqueness constraints.
- PostgreSQL regressions cover saved-result replay, active successors,
wrong task or agent, missing receipts, unadmitted wakes, ownership
races, and failed workspace persistence.
- The execution contract and verification maps describe the recovery
boundary.

## Verification

- Red: the saved monitor regression remained `retryable_failure` instead
of `committed` on unpatched code.
- Red: the scheduler admitted a wake while terminal-run finalization
remained retryable.
- Red/green: two PostgreSQL cases reproduce timeout during workspace
recovery for scheduled and manual checks. Before the review repair, both
remain `retryable_failure` with `monitor_wait_authority_lost`.
Afterward, both commit, apply board escalation once, preserve the saved
result, and enqueue zero provider wakes. New completion still rejects
the expired schedule.
- Typecheck: `pnpm -r typecheck` passed.
- Build: `pnpm build` passed.
- Maps: `node scripts/check-maps.mjs` passed.
- Review: Greptile 5/5 and Ponytail Paperclip Review 5/5 on the current
head, with no unresolved findings. Both reviews are static; execution
evidence is recorded separately above and below.
- Linux staging: the original repair passed 170 tests across monitor
integration, scheduling, status arbitration, and workspace finalization.
The expanded suite passes all 172 tests, including both new timeout
regressions.
- Live acceptance: deployed the original repair to the authorized Linux
ARM64 self-hosted instance. The stranded saved result finalized
automatically; the original task then completed through normal
admission, with its final answer persisted after browser reload. The
other original task was already complete and its external delivery was
verified without repeating it.
- The initial Mac regression run passed 68 tests, but three suites
failed during embedded PostgreSQL startup. A subsequent focused run
confirmed the host had exhausted its PostgreSQL semaphore allowance.
Linux verification uses isolated databases; the local failure logs
remain preserved.
- The local full test suite is not claimed as passed. It is blocked by
the same PostgreSQL startup limitation; full-suite CI passed on head
`8bc29d1b7783446f397b858e558083570a96bb66`
([run](https://github.com/paperclipai/paperclip/actions/runs/39447913466)).

## Risks

- A delivery match must not grant new execution authority. The lookup
requires the original run's server receipt and a matching company,
agent, task, wake, and admitted successor. The locked commit rejects
old-run checkout ownership and permits no status effects.
- Workspace persistence must succeed before settlement. Its existing
failure path remains effective.
- The scheduler waits while a native finalizer is unfinished. Workspace
recovery must settle before dispatch; elapsed monitor limits transfer to
the existing scheduler recovery policy instead of stranding the result.
Neither settlement path renews a deadline or changes budget, approval,
pause, or provider authority.
- No schema, migration, credential, or provider configuration change.

## Model Used

OpenAI Codex, based on GPT-6, with tool use and code execution. The
exact backend model ID and context-window size are not exposed in this
