DottaandClaude Opus 5.5 8eabb13ebd fix(recovery): retry a system-woken run once when it lost its runner before any turn (#20873)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - A native run on a remote sandbox can lose its Runner process before
its same-run retry reattaches. The run then fails with
`runner_remote_process_identity_unavailable`
> - After saved-work recovery, the server requests one Retry by itself,
but only for user wakes. System wakes (monitors, automatic assignments)
rest on the visible Retry
> - On staging, a monitor wake's run lost its Runner before it started
any provider turn. Nothing it did could be repeated, but the task stayed
blocked until a person clicked Retry
> - This pull request lets that one case continue automatically, once,
under the run's responsible user
> - The benefit is that a system-woken task whose run never reached a
provider turn continues without a person

## Linked Issues or Issue Description

**What happened?**
On staging, a monitor wake (`issue_monitor_due`) started a remote native
run. Its `session.snapshot` command timed out before any turn. The
same-run retry found the Runner process gone (`process_not_running`,
lifecycle `ready`) and the run failed with
`runner_remote_process_identity_unavailable`. The run had no turn event
and no tool event. Saved-work recovery recovered the files, but
`requestInterruptedNativeTurnRetry` refused with `not_user_request`, so
the task stayed blocked on a manual Retry.

**What did you expect to happen?**
When the run proves that it did no provider turn, the server requests
the Retry once by itself, as it does for user wakes.

**Steps to reproduce**
1. A system wake starts a remote native run.
2. The run fails before any turn event, and the same-run retry finds the
Runner gone.
3. Saved-work recovery completes. No Retry is requested; the task waits
for a person.

## What Changed

The rule that changed, exactly: in `requestInterruptedNativeTurnRetry`
(`server/src/services/heartbeat/restart-interrupted-turn.ts`), a run
whose wake was not requested by a user used to stop with
`not_user_request` in all cases. Now it requests the task Retry only
when all of these are true:

- the run failed with one of the existing reattachment-loss codes
(unchanged gate);
- a positive durable record proves that no turn was ever issued: the
run's last `native.remote_runner_recovery_failed` event carries
`remoteRunnerRecovery` with `stage: process_verification`, `reason:
process_not_running` and `providerTurnIssued: false`;
- the run also recorded no turn event and no tool event;
- the run has a `responsibleUserId`; the Retry runs under that user;
- the run is not itself a `task_retry` run;
- the task is still open and assigned to the same agent (unchanged
gate).

An absence of run events is never enough: a turn can reach the provider
before its events are stored (Greptile, first review).

- New `withRemoteRunnerTurnProof` (`native-session-executor.ts`): when a
same-run reattachment is refused because the sandbox proved the Runner
process gone (exit 45, not an unreachable sandbox), the executor reads
the run's controller journal. The controller records each turn command
there before it sends it. Only when
`runnerdStateProvesNoRemoteProviderTurn` holds (just
`run.prepare`/`session.open` and maintenance commands such as
`session.snapshot`, and only session-open events) does it add
`providerTurnIssued: false` to the diagnostic. This is the same proof
that restart recovery already uses for `bootstrap_incomplete`.
`RemoteRunnerRecoveryDiagnostic` keeps the field only as `false`.
- Which staging shapes this covers: a run whose journal holds no turn
command. Whether c14bab19 (the `session.snapshot` timeout) qualifies
depends on its controller journal, which staging does not expose; if its
journal held a `turn.start`, it stays on the manual Retry floor.
32376b3a (`turn.submitted`, then a `turn.start` timeout) always stays on
the floor.
- Everything else about system wakes is unchanged: without the journal
proof, with any turn or tool event, or without a responsible user, a
system wake still rests on the visible Retry.
- Bounded: the Retry uses the existing idempotency key
`restart-interrupted-turn:<runId>`, so it is requested at most once per
run. Its successor is a user-attributed `task_retry` run, so if that run
also loses its Runner, the existing `automatic_retry_used` rule leaves
it on the visible Retry. No loop is possible.
- Attribution: `requestTaskRetry` records `issue.retry_requested` with
actor `restart-recovery` on behalf of the run's responsible user.
Admission keeps every gate (saved-work recovery, stop proof, approvals,
pause, budget, ownership).
- Tests in
`server/src/services/workspace-recovery-retry-copyback.test.ts`: a
positive case (monitor wake, Runner proven gone, journal proof),
including the second-loss `automatic_retry_used` check. Negative cases:
no run events but no journal proof (the Greptile shape), a settled turn,
a tool event, no responsible user.
- New
`server/src/services/native-runtime/remote-runner-turn-proof.test.ts`:
the proof is recorded only for a journal of session commands; not for a
`turn.start` command, a committed turn event, an unreadable journal, or
an unreachable sandbox (`probe_transport_failed`).
- `doc/execution-semantics.md`: describes the rule.

## Verification

- `cd server && pnpm exec vitest run
src/services/workspace-recovery-retry-copyback.test.ts`: 83 passed.
- Red on master (product hunk removed): the positive case fails with
`expected { requested: false, … } to match object { requested: true }`.
- Red on the first head (a244ad3b): the "no run events but no journal
proof" case is requested automatically; CI's `run-completion.test.ts`
("replays saved user intent … system_wake") failed for the same reason.
Both pass now.
- `pnpm exec vitest run
src/services/native-runtime/remote-runner-turn-proof.test.ts`: 4 passed.
`native-session-executor.test.ts`, `run-completion.test.ts`,
`runtime-execution.test.ts`: 1571 tests passed (one local `afterAll`
hook timeout under load).
- `cd server && pnpm exec tsc --noEmit -p tsconfig.json`: passes.

## Risks

- Low to medium. A system-woken task can now start one new run without a
person. This happens only when the controller journal proves that no
turn command was ever issued, so no provider work or tool side effect
from that run can be repeated. The Retry starts a fresh provider
session, like a manual Retry.
- The Retry runs with the run's responsible user's authority. That user
already authorized the failed run. If the user lost access,
`requestTaskRetry` refuses and the visible Retry remains.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), with tool use and code execution
in an agent harness.
