CI / build (push) Has been cancelled
Fix 10 audit bugs: path prefix matching, verdict parsing, CORS, stale-task detection, phase mapping
Batch 1 (High severity):
- Bug 1: --audit cat3 now checks .automaton/tasks/ paths
- Bug 4: Verdict PASS/FAIL uses structured ## Status: line parsing
- Bug 5: register-guards.sh checks .json/.jsonc, writes plugin key, strips comments
- Bug 7: --can-edit/--scope-check path prefix uses os.sep boundary

Batch 2 (Medium/Low severity):
- Bug 2: migrate-project.sh find command parentheses for -prune binding
- Bug 3: vram_detect model prefix matching with known-suffix whitelist
- Bug 6: dashboard reads .state file before artifact heuristic fallback
- Bug 8: removed wildcard CORS, added security headers (nosniff, DENY)
- Bug 9: stale-task detection uses .state.lastedit instead of .state mtime
- Bug 10: TEST_PLAN.md maps to test_design (was implement)

249 tests pass (up from 235). All 10 tasks driven through full workflow to completion.

Implementation: fix-stale-task-mtime-proxy

Bug

--can-edit used .state file mtime as a proxy for "last edit activity" to detect stale tasks. But .state is modified by phase transitions, not by actual editing. A task in implement phase for 30+ minutes would be flagged as stale even if the developer was actively editing files the whole time, because .state mtime only reflects the last phase transition.

Fix

  1. Added _get_edit_timestamp() — reads .state.lastedit mtime if it exists, falls back to .state mtime for backward compatibility
  2. Added _touch_lastedit() — creates/updates .state.lastedit file
  3. --can-edit now calls _touch_lastedit() on ALLOWED responses (both project-level and task-level paths), recording actual edit activity
  4. Staleness check uses _get_edit_timestamp() instead of raw .state mtime
  5. Added .state.lastedit to NON_ARTIFACT_FILES so it's not treated as a phase artifact
  6. --same-session uses _get_edit_timestamp() for consistent activity tracking
  7. --touch command now touches .state.lastedit instead of .state
  8. Added staleness check to the single-task --can-edit --task path (previously only project-level --can-edit checked staleness)

Files Changed

  • scripts/status.py: Added _get_edit_timestamp(), _touch_lastedit(), updated cmd_can_edit(), cmd_same_session(), cmd_touch(), NON_ARTIFACT_FILES
  • tests/test_status.py: Added TestStateLastEdit class with 5 tests and TestTestPlanPhaseMapping class

Tests

  • test_can_edit_creates_lastedit_on_allowed: Verifies .state.lastedit is created on ALLOWED
  • test_can_edit_creates_lastedit_with_file_scope: Same for file-scoped can-edit
  • test_stale_uses_lastedit_not_state_mtime: Old .state + recent .state.lastedit → not stale
  • test_stale_when_lastedit_old: Recent .state + old .state.lastedit → stale
  • test_falls_back_to_state_mtime_without_lastedit: No .state.lastedit → falls back to .state mtime
  • All 249 tests pass
