DottaandPaperclip eb640ec129 fix(execution): keep blocked wakes waiting without repeated runs (#13236)
## Thinking Path

> - Paperclip manages AI agents and their work.
> - Wake admission decides when a task can create an execution run.
> - Recovery can prohibit replay while the previous execution needs
review.
> - Dependency reconciliation kept creating runs before dispatch
rejected that same hold.
> - Each rejected run added another startup notice without doing useful
work.
> - This change checks the hold during admission and records repeated
automatic waits once.
> - Tasks keep their messages and can resume when the current gates
permit execution.

## Linked Issues or Issue Description

Related changes: Refs #13173 (stale completed-task continuations). Refs
#12651 (dependency waits during recovery).

**What happened?**

A blocked task with completed dependencies can remain under a durable
execution reconciliation hold. Each scheduler pass created a queued run.
Dispatch then cancelled it before the adapter started. The skipped wake
did not satisfy dependency wake deduplication, so this repeated and
filled the conversation with “Couldn't start” notices.

**Expected behavior**

A known execution hold creates a waiting diagnostic without a run.
Repeated automatic observations share that diagnostic. Clearing the hold
permits a new wake only after the other gates pass. New comments remain
available for the next eligible execution.

**Steps to reproduce**

1. Assign a blocked task with a completed blocker.
2. Give the task an active reconciliation action, or a resolved action
whose automatic recovery evidence still prohibits replay.
3. Run dependency reconciliation repeatedly.
4. Observe repeated cancelled pre-start runs on the base branch. This
branch creates no runs while held and admits work after the effective
hold clears.

## What Changed

- Check effective execution holds under the issue admission lock before
inserting runs. Keep the final dispatch check for races.
- Share automatic wait diagnostics across producers, wake keys, and
service restarts. Apply the helper to reconciliation, dependencies,
pause holds, availability, budgets, and disabled heartbeats.
- Preserve ordinary comment and interaction receipts during execution
holds. Prevent release from draining them while replay is blocked. Keep
external-chat receipt authorization intact.
- Group empty pre-start reconciliation cancellations into a neutral
waiting notice. Keep started runs and the full run history.
- Document the waiting contract and add database-backed, UI, and browser
regressions.
- Stabilize two existing verification tests: allow the asynchronous chat
lease transition a bounded five-second wait, and accept either
legitimate damaged-session refusal while retaining exact
archive-evidence assertions.

## Verification

Passed targeted tests:

- `pnpm exec vitest run
server/src/__tests__/heartbeat-issue-liveness-escalation.test.ts
server/src/modules/wake-queue/adapters/postgres.test.ts` — 28 tests.
- `pnpm exec vitest run ui/src/components/TaskChatThread.test.tsx` —
covered in the initial combined test run; UI suite passed.
- Run-dispatch adapter tests passed in the combined gate regression run.
- `pnpm exec vitest run
server/src/__tests__/durable-chat-wakeup.test.ts` — 41 tests, including
held receipt replay, promotion, and revoked access.
- `PAPERCLIP_E2E_PORT=3294 pnpm test:e2e
tests/e2e/acp-stop-continuation.spec.ts` — all 3 browser scenarios pass.
Repeated held messages create no additional runs or provider prompts and
do not replay writes.
- `pnpm check:token-gates`
- `pnpm check:module-boundaries`
- `git diff --check`

`pnpm -r typecheck` and `pnpm build` pass.

The full local `pnpm test:run` invocation did not finish green: it
encountered exhausted local PostgreSQL shared-memory slots, a missing
fresh-worktree runner test binary, and tests loaded across in-flight
edits. The affected chat/database suites passed on rerun (81 tests), and
the targeted lifecycle/recovery verification passed (3 tests). After
building the runner test binary, the full native session suite also
passed (37 tests). Final-head [CI run
34621288475](https://github.com/paperclipai/paperclip/actions/runs/34621288475)
passed on `8659618b0ed2b98df002a28f4c1bd97321b0db04`, including all
server/workspace test shards, all three browser shards, runner
verification, typecheck, build, release dry run, and the aggregate
verification gates. All 31 reported checks passed; the two conditional
Storybook checks were skipped as intended. Greptile reviewed that exact
commit at 5/5 with no unresolved review threads.

## Risks

The wait record is diagnostic only. It must never count as a delivered
wake or bypass a current gate. Tests cover repeated and concurrent
admission, resolved no-replay evidence, a remaining dependency after
hold clearance, deferred comments, and release gating. Explicit user
requests and authorized chat receipts do not share automatic
diagnostics. No migration or historical data deletion is required.
Existing provider retry budgets remain unchanged.

## Model Used

OpenAI GPT-6 through Codex. The runtime does not expose the exact hosted
snapshot ID or context-window size. Used repository inspection, code
editing, command execution, tests, and review tools.
