DottaandClaude Opus 5.5 a994a648f1 fix(workspaces): name copy-back failures on the run and end failed save operations (#19187)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - A native run in a Daytona sandbox saves its workspace after the
provider turn. This save is "copy-back".
> - On staging, about 20 runs kept a saved result, but copy-back failed
three times. The issues became blocked with
`native_workspace_sync_out_retry_exhausted`.
> - #19152 added a redacted cause for a sandbox command that exits with
an error. Three gaps stayed open: a provider that refuses the command
still gives a bare code, the run does not show the cause, and the failed
save operation stays "running".
> - The first failure also had the wrong name. The runner kept the
result but did not prove a durable suspension. The executor reports this
as `native_session_lease_lost`, and the workspace operation shows only
that text.
> - This pull request names each of these failures with closed, redacted
labels. It also ends a failed save operation as "failed".
> - The benefit is that operators can see why copy-back failed and which
save is still active. Retries and saved results do not change.

## Linked Issues or Issue Description

Refs #19152, #19145. These are the earlier copy-back diagnostics and
retry-scheduling repairs. This PR does not duplicate them.

**What happened?**
A native task ran in a Daytona sandbox and its result was accepted. The
run then failed with `native_workspace_sync_out_retry_exhausted`. The
run had no error text. The automatic copy-back retries each failed in
under one second, with only `workspace_sync_out_failed`. The final
`remote_workspace_snapshot` operation stayed "running" after the retries
stopped. The first `workspace_finalize` operation showed only
`native_session_lease_lost`. The run log showed that the runner shutdown
timed out before durable suspension. The lease was not lost.

**Steps to reproduce**
1. Run a native task in a Daytona sandbox until its result is accepted.
2. Make the sandbox provider refuse the copy-back command (for example,
a lease that is no longer active), so that no exit status comes back.
3. Let the automatic retries stop. Then read the run and its workspace
operations.

**Expected behavior**
The run, the coordinator, and the failed operations name a redacted
cause. The failed save operation is "failed" with a finish time.

**Actual behavior**
The run has no cause. The save operation stays "running". A provider
refusal keeps only the bare `workspace_sync_out_failed` code.

## What Changed

- `remote-workspace-transport.ts`: the provider can throw instead of
returning an exit status for the copy-back helper, the capture, or the
archive download. `remoteWorkspaceFailureCause` then returns
`remote_workspace_operation_failed: operation=<op> transport=<label>[
code=<ERRNO>]`. The label is from a closed list (for example
`sandbox_lease_inactive`, `permission_denied`, `sandbox_not_running`,
`transport_timeout`, `transport_closed`, `daytona_sandbox_not_found`,
`provider_error`). Provider text is never copied into the cause. The
thrown error does not change, so preparation errors,
`classifyNativeWorkspaceFailure`, and other callers keep their
contracts. Archive-safety and Git-metadata refusals get no label,
because they have their own diagnostics.
- `remote-workspaces.ts`: when the last active invocation of a save
fails, the save operation becomes "failed" with `exitCode`,
`finishedAt`, a redacted `stderrExcerpt`, and `metadata.lastFailure`. A
retry of the same boundary sets it to "running" again. A success sets it
to "succeeded". After the final save commits, a failed save is retired
for export cleanup in the same way as a running save.
- `remote-workspace-snapshot-retention.ts`: a failed save that is not
retired keeps its snapshot pinned, as it did while it was "running". Its
retry can still use an uploaded snapshot.
- `native-run-finalizer.ts` and `native-workspace-finalizer.ts`: the
redacted cause of each copy-back attempt goes to the coordinator
`failureDetail.failureCause` and the run `resultJson.failureCause`. When
retries stop, the run error adds `Last cause: <cause>`. The server
checks the cause against a fixed grammar again before it writes it. A
cause with a path or other text is dropped.
- `native-post-result-failure.ts` (new), `native-session-executor.ts`,
`runtime-execution.ts`: a failure after an accepted result gets the
label `runner_settlement_incomplete` when the runner did not prove a
durable suspension. The failed `workspace_finalize` operation records
this closed diagnostic as `failureDiagnostic`. The coordinator records
it as `native_post_result_failure: category=<label>`. The control code
`native_session_lease_lost` and its fencing do not change.

## Verification

- Red, before the fix (the new tests run against `master` source):
- 4 provider-refusal cases and the archive download failure: no redacted
cause was available, so the copy-back recorded only the bare code.
- Failed save, with only the transport fix applied: `- "status":
"failed"` / `+ "status": "running"`.
- Run cause after retries stop: `expected null to be
'remote_workspace_operation_failed: …'`.
- Green, after the fix:
`cd server && npx vitest run
src/services/remote-workspace-transport.test.ts
src/services/remote-workspace-save-concurrency.test.ts
src/__tests__/native-workspace-finalization-work.test.ts
src/services/native-runtime/native-post-result-failure.test.ts
src/services/remote-workspaces.integration.test.ts
src/services/remote-workspace-snapshot-retention.test.ts` passes.
- Safety cases:
- The failed save is retried on the same boundary operation, records
"succeeded", and keeps the saved file bytes.
- `daytona_sandbox_not_found` is still classified as
`workspace_sync_out_unrecoverable`.
  - An archive-safety refusal keeps its exact text.
  - A forged cause with a path never reaches the run or the coordinator.
- A run-level timeout cause (`remote_workspace_operation_timed_out:
capture (configured timeout 300000ms)`) reaches the run and the
coordinator.
- `heartbeat-native-remote-failure-retention.test.ts` passes: a
preparation failure keeps its exact run error.
- The existing integration tests for retired saves, poisoned
reservations, duplicate invocations, and snapshot retention pass. They
prove export cleanup and identity protection.
- `tsc --noEmit` for `server` reports no errors.
- Not done: a live Daytona copy-back. This PR adds diagnostics and
corrects the operation state. It does not change when a retry runs.

## Risks

- Thrown copy-back errors do not change. Only the recorded cause is new.
The `daytona_sandbox_not_found` and archive-safety classifications are
tested.
- A failed save operation is now "failed" before the final save commits.
Retirement, export cleanup, and snapshot pinning now also select these
failed rows. They select only rows with `lastFailure` and no retirement
receipt.
- Privacy: each new cause is a closed label or a server-built code. The
server checks it again with an anchored grammar before it writes the
run. No sandbox output, path, or message text is stored.
- The retry count, the retry delay, and the classification of each
failure do not change. No provider turn is added.
