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.

Code Review: fix-stale-task-mtime-proxy

Reviewed Files

  • scripts/status.py (_get_edit_timestamp(), _touch_lastedit(), cmd_can_edit(), cmd_same_session(), cmd_touch(), NON_ARTIFACT_FILES)

Changes

  1. Added .state.lastedit file as the stale-task timer source
  2. _touch_lastedit() called on ALLOWED --can-edit responses
  3. _get_edit_timestamp() reads .state.lastedit with fallback to .state mtime
  4. Added staleness check to single-task --can-edit --task path
  5. --touch now touches .state.lastedit instead of .state

Analysis

  • Correctness: Using .state.lastedit (touched on actual edit activity) is a better proxy for staleness than .state mtime (which only reflects phase transitions)
  • Backward compatibility: Falls back to .state mtime when .state.lastedit doesn't exist
  • Non-artifact: .state.lastedit correctly added to NON_ARTIFACT_FILES to avoid being treated as a phase artifact
  • Single-task path: Adding staleness check to --can-edit --task makes enforcement consistent across both code paths
  • --touch command: Updated to touch .state.lastedit — consistent with the new activity tracking model

Verdict: PASS

The fix is well-structured, maintains backward compatibility, and correctly addresses the mtime proxy issue. Tests cover creation, staleness detection, and fallback behavior.
