Devin FoleyandPaperclip edb9d29942 fix(recovery): preserve Retry authority and reopen cross-task cases (#18997)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Tasks keep execution identity and saved workspace files separate
from control-plane updates.
> - A scanner can have permission to reopen a case while its run cannot
restore that case's files.
> - Retry can also follow a preparation failure that has no
recovery-action record.
> - Both paths can accept valid work but leave the target unable to run.
> - This change restores files under the target executor and saves
admitted Retry authority on the canonical receipt.
> - Existing workspace, user, source and successor checks still apply.

## Linked Issues or Issue Description

**What happened?**

An authorized agent updates another closed task. The route tries to
restore the target workspace under the caller's run identity and returns
`403 Task workspace run identity is unavailable`.

A separate failure occurs when a normal board Retry follows a
pre-provider preparation failure. Admission has no recovery-action row
on which to save continuation authority. Dispatch then fails with
`continuation_user_authorization_missing`.

**Expected behavior**

Accept the authorized task update. Restore its terminal workspace when
the target's admitted executor starts. An admitted Retry must retain its
exact dispatch authority even when the predecessor has no
recovery-action record.

**Steps to reproduce**

1. Complete a task with an isolated workspace. From a different running
task, use an authorized comment or PATCH with `resume: true` on that
closed task.
2. Separately, fail native preparation before provider work starts, with
no recovery-action row. Submit board Retry, admit its successor, and
build the execution continuation.
3. Before this change, the first path returns 403 and the second rejects
its admitted authority.

**Paperclip version or commit**

Reproduced against `e968131efa7e63d321f3bcca8d47a62513c2efb4`. Rebased
onto `afbc5a885b5`.

**Deployment mode**

Server-managed native task execution. Tests use real PostgreSQL and
temporary workspace files.

Related PRs: #16927 covers terminal workspace races. #17916 retains
exact native export sources. Neither covers these route and Retry
receipt failures. A GitHub search found no duplicate. ROADMAP.md was
checked; this is a recovery bug fix.

## What Changed

- Defer workspace restoration only for authorized cross-task comments
and updates from a live run. Checkout keeps its existing workspace
identity checks.
- Restore the target's selected terminal workspace under its own
admitted run. Preserve its saved files and existing source checks. Leave
manually archived workspaces unchanged.
- Store server-created continuation authority on the canonical admitted
Retry receipt when no source recovery-action record exists. Existing
action records remain authoritative. Read the fallback only after
matching the company, task, agent, user, source, generation and
successor.
- Add route and PostgreSQL regression tests. Document both paths.

## Verification

- Red: both cross-task route tests returned the observed 403 before the
route fix.
- Red: the target executor could not reuse its archived terminal
workspace before the restoration fix.
- Red: an admitted preparation Retry with no recovery-action row failed
with `continuation_user_authorization_missing` before the receipt fix.
- Green: 419 recovery and continuation tests pass, plus 183 focused
route, environment and Retry tests. The assembled heartbeat test starts
the agent in the same terminal worktree and verifies both its unpushed
commit and uncommitted file bytes. It fails before the restoration fix.
- Negative cases reject wrong Retry runs, users, source runs,
generations, unadmitted receipts and missing authority. The original
failed run stays unchanged. Workspace tests verify saved file bytes.
- Full `pnpm build`, `pnpm -r typecheck`, `pnpm check:module-boundaries`
and `git diff --check` pass.
- The full suite found an existing assembled chat authority regression:
clearing a recovery-action record could be bypassed by the new fallback.
The fix now writes the fallback only when that source has no action
record. That assembled regression passes with the original test
unchanged.
- Full `pnpm test:run` is running again. Its first attempt also hit an
unrelated ancestor skill-root lookup for a missing Slack skill. The
rerun uses a temporary untracked link to the repository's own bundled
skills. This link is excluded from the PR. Full-suite completion and
hosted CI are pending.
- Hosted CI has multiple runner interruptions. E2e shard 1/8, server
shards 3/12, 8/12 and 12/12, and workspaces-a shard 1/2 show runner
shutdown signals. E2e shard 5/8 and server shards 1/12 and 2/12 have
GitHub annotations reporting lost runner communication; their logs
return 404. The `ci / verify` assertion failed because the general-test
matrix was cancelled. GitHub rejected job and failed-workflow reruns
while this workflow is still running. Rerun the interrupted checks after
it settles.
- Greptile reviewed exact head
`a1e3929aedb1ee3bfcd001f4ebb1510106bf4070` at 2026-11-04 17:37 UTC: 5/5,
with no new blocking findings and no unresolved review threads.

## Risks

- A deferred workspace restore can still fail at target admission. The
run keeps the existing workspace failure path; this change does not
bypass file recovery or provider stop checks.
- Retry receipts now store server-created authority. Existing action
receipts remain valid. No schema migration is required.
- Local regression tests establish the software behavior. The new
revision has not been deployed to a hosted instance.

## Model Used

OpenAI `gpt-6.1-sol` through the Codex harness in T3 Code, with xhigh
reasoning, repository inspection, tool use and code execution. The
context-window size is not exposed by the runtime.
