…ists

- Bump EXEMPTIONS['execution/backends'] from 11 to 12 to account for
  the new _probe_cache.py module.
- Add _probe_canary.py to the root module allowlist in
  test_root_module_allowlist.
- Add _probe_canary to _cmd_runner MODULE_CASCADE_CORE consumers
  (run_gh import).
- Add _probe_canary to LAYER_CASCADE_CONSERVATIVE['core'] and as a new
  top-level entry in both conservative and aggressive cascade maps.
- Add _probe_cache to SINGLETON_ALLOWED_MODULES (module-level
  timedelta() call for PROBE_CACHE_TTL constant).
- Add _probe_canary.py atomic_write site to _LEGACY_JSON_WRITES
  allowlist (CanaryState save — 3-field state file, intentionally
  unversioned).
- Add the two new source files to .autoskillit/test-source-map.json
  so the test filter cascade maps changes to their tests.

…output

Addresses two reviewer findings in _probe_canary.py:
- Replace --body CLI arg with --body-file tempfile per AGENTS.md §3.4 mandate
  (issue create and issue edit both now write body to a NamedTemporaryFile)
- Wrap json.loads(result.stdout)["number"] in try/except (JSONDecodeError, KeyError)
  and re-raise as RuntimeError with stdout content for diagnostics

…ilure

- Correct module docstring from IL-0 to IL-1 (file lives in execution/backends/)
- Add logger.debug call on OSError in write_probe_cache instead of silent pass

- test_swallows_oserror: add assert not p.exists() to catch regressions
  where write_probe_cache writes to an unexpected path
- test_load_corrupt_file_returns_zero_state: add schema_streak == 0 and
  last_issue_number is None assertions to match the full zero-state contract

…anary.py

The json.dumps call in CanaryState.save() shifted from line 48 to 50 after
adding os and tempfile imports. Update the _LEGACY_JSON_WRITES allowlist entry.

…e helper

- Change "IL-0 module" to "IL-1 module" in _probe_canary.py docstring to match
  _probe_cache.py convention (module imports from autoskillit.core → IL-1)
- Extract duplicated NamedTemporaryFile/write/run_gh/finally:os.unlink pattern
  into _run_gh_with_body_file(args, body) helper, eliminating the duplication
  between the issue edit and issue create branches

- test_returns_none_on_naive_timestamp: change hardcoded "2026-06-13T10:00:00"
  to "2000-01-01T00:00:00" so test is not tied to the current date
- test_swallows_oserror: wrap write + assert in try/finally so readonly-dir
  chmod is restored even if the test assertion fails

…it failure

- test_ensure_issue_creates_new: assert '--body-file' in args inside the create
  branch of mock_run_gh to catch regression to inline --body
- test_ensure_issue_updates_existing: same assertion in the edit branch
- test_ensure_issue_logs_on_edit_failure: add structlog.testing.capture_logs()
  assertion to verify logger.warning('canary_issue_edit_failed') is emitted

…e number

- test_swallows_oserror: move assert not p.exists() after the finally block so
  it runs after chmod(0o755) restores directory access (chmod 0o444 removes
  execute bit, causing PermissionError on os.stat inside the try block)
- test_schema_version_convention: update _LEGACY_JSON_WRITES entry for
  _probe_canary.py from line 50 to 51 (shifted by added subprocess import)
