DottaandPaperclip 7c016c049b perf(workspaces): wake terminal cleanup from committed changes (#16282)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agents use execution workspaces to retain their files and Git
branches.
> - A reaper closes eligible workspaces after their task tree is
terminal.
> - The reaper scanned every heartbeat tick and read Git before cheap
eligibility checks.
> - Permanent scans also query idle databases when no cleanup work
exists.
> - This pull request wakes cleanup after transaction settlement and
restores bounded work at startup.
> - The benefit is fewer scans while fresh cleanup guards continue to
protect retained work.

## Linked Issues or Issue Description

Related work: Refs #13619, Refs #11753. Those PRs bound scans or back
off unchanged candidates. This PR uses the transaction work coordinator
to remove the permanent reaper tick. It overlaps their early
terminal-state filtering but does not change their runtime restart
behavior or introduce a second Git scheduler cache.

**What existing behavior does this improve?**

Terminal workspace cleanup and Git inspection for workspace detail
reads.

**Subsystem affected**

Server orchestration, execution workspaces, and idle sleep admission.

**Current behavior**

The heartbeat tick scans workspace candidates every thirty seconds. It
runs Git before rejecting nonterminal trees, cooldowns, and active runs.
Display inspections expire after five seconds.

**Proposed behavior**

Recover workspace rows in bounded startup pages. Wake after relevant
issue, workspace, and pull-request work-product transactions settle.
Schedule the terminal tree cooldown or a five-minute eligibility retry.
Back off unchanged candidates across unrelated wakes, and invalidate
their backoff after relevant committed changes. Park empty and
nonterminal-only lanes. Reuse display inspections for thirty seconds.
Read fresh Git before destructive cleanup.

**Reason and benefit**

Avoid recurring database and Git work when no cleanup is possible.
Retain transaction admission holds, restart recovery, and fresh deletion
checks. Retention eligibility can wait for the next host wake; active
and failed recovery work still blocks sleep.

**Breaking changes**

No schema or API shape changes. Display Git state can lag by thirty
seconds. Cleanup eligibility retries can take five minutes.

## What Changed

- Add a terminal-workspace worker to the existing transaction work
coordinator and scheduler.
- Signal relevant writes before mutation on the owning transaction.
Outer transaction settlement wakes cleanup.
- Derive cooldown deadlines from the full company-scoped terminal task
tree. Continue bounded recovery pages without a permanent sweep.
- Bound unchanged candidate inspections to five minutes, retain at most
256 entries, and invalidate affected entries with scoped transaction
hints. Repeated wakes preserve the earliest inspection deadline.
- Collect deadlines from task trees already read by bounded pages.
Restore the cursor after a failed page and rescan commits received
during a rotation.
- Check terminal state, cooldown, and active runs before Git. Preserve
lifecycle locks, generation fences, and fresh final checks.
- Keep failed or incomplete recovery visible to idle admission. Preserve
the passive retention exception.
- Extend the bounded display cache to thirty seconds and document the
scheduling and wake limits.

## Verification

- Focused workspace, coordinator, cache, and local sleep suites: 111
tests passed with real local PostgreSQL and Git worktrees where
applicable.
- Final worker, display cache, and local sleep suites: 28 tests passed.
- The regressions prove three ineligible workspaces invoke zero Git
scans, cached clean display state cannot remove new untracked files, and
real producer notifications wait for outer transaction settlement.
- `pnpm -r typecheck` and `pnpm build` passed locally. Map and
module-boundary checks passed.
- Work-product and sleep-safety suites: 221 tests passed. Reopen and
issue-tree control suites: 46 tests passed. Final backoff, workspace,
worker, and work-product suites: 87 tests passed.
- Final workspace and worker suites: 81 tests passed. Deadline selection
performs zero database reads. A failed full page retries its unread
terminal workspace before recovery can park.
- Full CI coverage passed on head `2c397970f7`: general tests,
serialized server suites, runner verification, E2E shards, typecheck,
build, and the final verification gate. The duplicate serial local `pnpm
test:run` was stopped after full CI coverage passed; it is not reported
as a completed local pass.
- Greptile: 5/5 with both findings resolved. The security scan also
passed. No failing or pending PR checks remain.

## Risks

- Display state can be stale for thirty seconds. Destructive guards
bypass the display cache.
- Undelivered or otherwise ineligible terminal work retries after five
minutes instead of each heartbeat tick.
- Transaction signals cover the owning `createDb` scope. Direct SQL and
independent server processes require startup recovery.
- Local cooldown timers are maintenance hints. They do not establish an
external wake alarm or whole-instance sleep safety. Existing blockers
remain in force; failed bounded recovery keeps the host awake.

## Model Used

OpenAI GPT-6, model ID `gpt-6`, through Codex. Reasoning, repository
inspection, shell execution, and browser tools assisted the change. The
runtime does not expose the context-window size.
