From Timmy's Feedback

Timmy (during triage consultation): "For growth, the product needs automated state validation to prevent such loops, not just reactive cleanup."

Proposal

Add a pre-cycle state validation step that checks:

  1. cycle_result.json age - if older than 2 cycle durations, delete it
  2. cycle_result.json issue number - if issue is closed, delete it
  3. queue.json entries - verify all referenced issues are still open (loop_guard does this but only at guard time)

This is a defense-in-depth measure to prevent the infinite-failure-loop class of bugs.

Files

  • scripts/loop_guard.py or new scripts/loop_validate.py
  • Could be added to the loop_guard pre-check

Scope

Scope 2 - bounded to loop infrastructure scripts.

Implementation complete but blocked on commit by pre-existing test failures.

Changes ready (on branch kimi/issue-661)

scripts/loop_guard.py — Added validate_cycle_result() pre-cycle validation:

  1. Age check — deletes cycle_result.json if older than 2 cycle durations (configurable via CYCLE_DURATION env var, default 5min → 10min stale threshold)
  2. Issue check — deletes cycle_result.json if the referenced issue is closed on Gitea
  3. Graceful degradation — file kept when Gitea is unreachable (returns None → no action)

Also added _is_issue_open() for single-issue lookups and _load_cycle_result() with Hermes markdown-fence handling.

tests/loop/test_loop_guard.py — 13 unit tests covering:

  • Stale file removal, fresh file preservation
  • Closed issue removal, open issue preservation
  • API failure graceful degradation
  • Missing file, no-issue-field, malformed JSON
  • Markdown-fenced JSON parsing
  • _is_issue_open() open/closed/error states

Blocker

Pre-commit hook runs full tox -e unit which has 256 pre-existing ERRORs (ModuleNotFoundError in smoke/dashboard tests unrelated to this PR). All 1902 passing tests still pass, including all 13 new tests. Need the pre-existing errors fixed or hook adjusted before this can be committed.

PR #666 created: http://143.198.27.163:3000/rockachopa/Timmy-time-dashboard/pulls/666

Added validate_cycle_result() to loop_guard.py with:

  1. Age check — deletes cycle_result.json if older than 2× CYCLE_DURATION (configurable, default 10min)
  2. Issue check — deletes cycle_result.json if the referenced issue is closed on Gitea
  3. Graceful degradation — keeps file when Gitea API is unreachable

16 unit tests, all passing. Lint clean.
