DottaandClaude e33ede9a8a fix(native): settle a restart-orphaned write_document from its transactional receipt (#20674)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native run calls Paperclip tools such as `write_document`. The
runner saves each tool input durably before the server runs the tool,
and the server saves a result receipt
> - A control-plane restart can cut a `write_document` call after the
runner saved its input and before any result was saved
> - Recovery then has no proof of the outcome. A call from an earlier
server process settles as "unknown outcome" (#20628). A call the current
server process admitted stays pending, close cannot prove that the
provider drained, and the session quarantines
(`native_session_cleanup_quarantined`). A person must click Retry
> - `write_document` saves its revision and its idempotency receipt in
one database transaction, under the run and issue row locks. The
revision is also compare-and-swap on `baseRevisionId`. So the receipt is
a durable outcome record: present means applied, absent means not
applied
> - This pull request makes recovery use that proof. Recovery runs the
same receipt-guarded write. It replays the saved result, or it applies
the write exactly once
> - The benefit is that an orphaned `write_document` settles with its
real result. The document is never written twice, and the run does not
need Retry for this call

## Linked Issues or Issue Description

**What happened?**
Daytona restart-chaos wave `w-20261110T174930-s9205`, task t01 (codex,
workload C1, fault RR2). A restart cut a `write_document` call. The
close settlement showed `semanticTools.pending: [{ operationId:
"write_document", callId: "exec-8b79ab78-…" }]` and `providerDrained:
false`. The session quarantined with
`native_session_cleanup_quarantined`, and the task needed Retry. Since
#20628, a call that an earlier server process admitted settles as
`tool_call_interrupted_by_restart` with an unknown outcome. The agent
then has to guess whether the write applied.

**Expected behavior**
When a durable record proves the outcome, recovery uses it. A write that
applied returns its saved result. A write that did not apply runs once.
When the record cannot prove it, the call stays as it is today.

**Steps to reproduce**
1. On master, run `pnpm --filter @paperclipai/server exec vitest run
src/services/native-runtime/paperclip-runner-tool-authority.test.ts -t
"orphaned"`.
2. `authority.recover()` returns `null` for a `write_document` that has
no receipt, so the call stays unsettled.

Refs #20628, #20639, #20507

## What Changed

- `PaperclipRunnerToolAuthority.recover()` now settles `write_document`
through its transactional receipt (`#recoverTransactionalWrite`). It
runs the same receipt-guarded mutation as an ordinary call. If the
receipt exists, it returns the saved result and writes nothing. If no
receipt exists, it applies the write once.
- A definite refusal that rolls the transaction back (a 4xx such as a
stale `baseRevisionId`, a reused idempotency key, invalid input) settles
as a tool error. Any other failure leaves the call unsettled, as before.
- The set of operations with this proof is explicit:
`TRANSACTIONAL_RECEIPT_OPERATIONS` contains only `write_document`. Other
tools keep their current recovery rules.
- New test: an orphaned `write_document` with no receipt applies once; a
second recovery and a late original call replay the receipt; an applied
write recovers its saved result; a stale base settles as a tool error
with no change.
- Updated test: a reused idempotency key with other input now settles as
an `paperclip_runner_tool_idempotency_conflict` tool error instead of
staying pending. The receipt proves that this call can never apply under
that key.
- Docs: `packages/paperclip-runner/docs/durable-recovery.md` (semantic
operations that outlive a turn) and a new design note,
`doc/plans/2026-11-10-durable-turn-start-and-tool-call-records.md`. The
note also covers the second change (an ACPX turn start cut off before
the prompt reached the provider), which comes in a separate pull
request.

## Verification

- Red on master, green here: `pnpm --filter @paperclipai/server exec
vitest run
src/services/native-runtime/paperclip-runner-tool-authority.test.ts` (43
passed).
- `pnpm --filter @paperclipai/server exec vitest run
src/services/native-runtime/native-runner-restart-recovery.integration.test.ts`:
178 passed. One unrelated ACPX timing test failed once under load and
passed when run alone.
- Server typecheck: `npx tsc --noEmit -p server/tsconfig.json` passes.
- `pnpm verify` exits 2 (a runner doc changed), so required CI supplies
the broad coverage.
- Live restart-chaos wave: see the comment on this pull request.

## Risks

- Recovery can now apply a write that never applied before the restart.
This is the call the agent made, applied once. The write is
compare-and-swap on `baseRevisionId`, so it cannot overwrite a revision
that someone wrote after the agent read the document. That case settles
as a conflict error.
- Upgrade safety: no saved shape changes. Receipts saved by the previous
release have the same shape. A server on the previous release keeps its
current recovery for these calls.
- Time to first token: no change. This code runs only during recovery.
- No runner source changes, so no new runner image is needed.

## Model Used

Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, with tool use (shell,
file editing) in Claude Code. Extended reasoning was used.
