Thinking Path

  • Paperclip — платформа для управления AI-агентами, которые ведут задачи компании (issues, checkout, heartbeat)
  • Подсистема: серверные vitest-тесты Agents API (server/src/__tests__/)
  • Проблема: 2 flaky-теста в Agents CI / API Tests периодически падали под mock-isolation и в race по времени пробуждения ассайни
  • Без фикса CI периодически краснеет без реальной регрессии, что маскирует настоящие баги и тратит ресурсы на перезапуски
  • Этот PR добавляет defensive guard против NaN в readLiveRunsQueryInt и делает детерминированным тест wake-уведомления по комментарию аннотации
  • Польза: стабильный зелёный CI для Agents API Tests без flaky перезапусков

Linked Issues or Issue Description

Переоткрытие вместо закрытого #172 (flaky-тесты Agents CI / API Tests, тот же корень проблемы).

What Changed

  • readLiveRunsQueryInt: заменён Math.min(undefined - max, parsed) (даёт NaN под mock-isolation) на defensive Number.isFinite(max) guard.
  • Тест wake-уведомления по комментарию аннотации: user-comment на annotation теперь детерминированно будит assignee через queueAnnotationCommentWakeup (fire-and-forget после ответа), тест обновлён на expect + vi.waitFor + mockClear.

Verification

  • pnpm exec vitest run для затронутых файлов: guard-тест 3/3, annotation wake-тест 6/6 в двух последовательных прогонах (детерминированность подтверждена повтором).
  • pnpm typecheck (pre-push) — 0 ошибок.
  • Известный отдельный infra-timing flake (costs-DB) не относится к этому PR, не устраняется в его рамках.

Risks

Низкий риск: изменения ограничены defensive guard и детерминизацией существующего теста, поведение production-кода не меняется вне обработки edge-case NaN.

Model Used

Claude (claude-sonnet-4-6), Claude Code CLI, tool use (Bash/Edit/Read), без extended thinking режима.

The 'document annotation routes' tests asserted mockHeartbeatService.wakeup was NOT called
when a user comments on an annotation thread. But queueAnnotationCommentWakeup (upstream
'Guard document comment wake boundaries' #7766) intentionally wakes the assignee agent so it
sees a non-self user's comment. The wake is dispatched fire-and-forget after the response,
so the synchronous not.toHaveBeenCalled() assertion raced it → non-deterministic 'Agents CI /
API Tests' failure.

Update the two comment/thread-create cases to await the wake (vi.waitFor) and clear the mock
before the resolve step so the 'resolve does not wake' assertion stays valid. Test-only; the
forked wake behaviour is unchanged. 6/6 deterministic across repeated runs.

Run 35825 failed at infra level: 'failed to set up container networking: network
WORKFLOW-... not found' — the postgres service container never started (concurrent job on
the shared runner tore down the Docker network). Tests never executed; the NaN guard and
annotation-wake fixes on this branch are unaffected. Empty commit to re-run CI.
