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-dashboard-cors-origin

Reviewed Files

  • automaton/dashboard/ui/app.py (SECURITY_HEADERS, _send_json(), _send_error(), do_OPTIONS())
  • tests/test_app.py

Changes

Removed wildcard CORS headers (Access-Control-Allow-Origin: *), replaced with security headers (X-Content-Type-Options: nosniff, X-Frame-Options: DENY).

Analysis

  • Security: Removing wildcard CORS eliminates the risk of cross-origin attacks from malicious local web pages
  • Single-origin app: The dashboard is a local web app served from a single origin — CORS is unnecessary
  • Security headers: X-Content-Type-Options: nosniff prevents MIME type sniffing, X-Frame-Options: DENY prevents clickjacking
  • OPTIONS handler: do_OPTIONS() still returns 204 No Content (for preflight requests) but without CORS headers
  • Tests: Test assertions correctly verify absence of CORS headers and presence of security headers

Verdict: PASS

The fix eliminates a security vulnerability while adding useful hardening headers. Tests are properly updated.
