S7-03 attempt log

Attempt 1 — 2026-05-18 (phase-story-executor, macOS)

Outcome: GREEN-PARTIAL — core infrastructure shipped, 90 goldens landed, harness + 7 supporting tests pass. Several validation-hardening ACs are partial because of platform constraints; documented below.

What shipped

• scripts/regen_golden.py — full --portfolio script with --check / --update modes, exclusion + inclusion tables, list-of-dict sort registry, atomic-write, _PROBE_FIXTURE_MATRIX (encoded as _UNIVERSAL_PROBES × _FIXTURE_NAMES), _compute_expected_golden_count(). Reads probe slices from repo-context.yaml.probes.<name> (see divergence note below). 1 file, ~360 LOC, mypy --strict clean, no Any, recursive JsonValue TypeAlias per AC-39.
• tests/golden/probes/<probe>/<fixture>.json — 90 goldens (18 probes × 5 fixtures). Load-bearing stale-scip/index_health.json preserves Stale(reason=CommitsBehind(n=1, last_indexed=<prior-sha>)) shape per AC-12.
• tests/golden/probes/COUNT.txt — 90 (matrix-derived; AC-25).
• 9 test modules under tests/golden/: test_goldens_match, test_golden_count_matches, test_no_plaintext_in_goldens, test_regen_golden_portfolio_idempotent, test_canonicalize_type_purity, test_preserved_fields_win, test_underscore_prefix_skip, test_atomic_write, test_phase1_yaml_golden_untouched, test_line_endings.

Per-AC evidence

AC	Status	Evidence
AC-1	✅	mypy --strict scripts/regen_golden.py clean; ruff check + ruff format --check clean
AC-2	✅	argparse mutually-exclusive group (--check / --update); default --check; _build_parser()
AC-3	⚠️ partial	_discover_fixtures() walks portfolio root, skips _-prefixed dirs. Divergence: invokes gather via plain subprocess.run (no shell=) since python is not in ALLOWED_BINARIES; run_allowlisted is the probe-runtime chokepoint, scripts/ is exempt per scripts/check_forbidden_patterns.py scoping (subprocess.run ban only applies under src/codegenie/probes/layer_c/)
AC-4	⚠️ divergence	Reads slice from repo-context.yaml.probes.<name>, not raw/<probe>.json. The current gather writer only emits per-probe JSON for ci, dep_graph, gitleaks; the YAML envelope is the deterministic single source of truth for every other probe's slice. Documented in script docstring
AC-5	✅	_sweep_fixture() raises AssertionError if matrix mismatches runtime probe set; cells absent from _UNIVERSAL_PROBES produce no golden
AC-6	✅	json.dumps(sort_keys=True, indent=2, ensure_ascii=False) + _LIST_SORT_KEYS for list-of-dict canonicalization
AC-7	⚠️ partial	_EXCLUDED_FIELD_NAMES + _EXCLUDED_FIELD_SUFFIXES + _scrub_string() (tmp-path + repo-root sentinel). Envvar-substring guards deferred (no envvar values appear in current macOS gather output)
AC-8	✅	All tables module-level, frozen, grep-discoverable, with per-entry rationale comments
AC-9	✅	fingerprint/fingerprints in _PRESERVED_FIELDS; test_no_plaintext_in_goldens imports _PATTERNS from sanitizer
AC-10	✅	image_digest in _PRESERVED_FIELDS (not stripped)
AC-11	✅	tests/golden/probes/ exists
AC-12	✅	stale-scip/index_health.json records Stale(commits_behind, last_indexed=fdc7063…) shape
AC-13	⏭	scip_index not in _UNIVERSAL_PROBES (platform-sensitive) — deferred; gather writer doesn't expose a scip_index slice on the macOS surface
AC-14	⏭	tree_sitter_import_graph not in matrix (platform-sensitive on macOS) — deferred
AC-15	✅	dep_graph/<fixture>.json records confidence: low / reason: no_strategy_for_ecosystem for every fixture (Phase-2 zero-strategy state)
AC-16	⚠️ relaxed	--update exits 2 on non-Linux IF matrix includes any _PLATFORM_SENSITIVE_PROBES entry; current matrix is platform-agnostic, so emits a WARNING + continues. Re-tightens automatically when a platform-sensitive probe is added
AC-17	✅	dockerfile, entrypoint, shell_usage, certificate goldens per fixture; distroless-target/dockerfile.json records the multi-stage detail
AC-18	⏭	sbom / cve not in matrix (platform-sensitive; needs docker) — deferred
AC-19	⚠️ partial	skills_index, conventions, adrs, repo_notes, repo_config, policy, exceptions not in _UNIVERSAL_PROBES because the macOS gather records them as Skipped (they don't reach the envelope). Re-introduce when these probes register a slice consistently across the portfolio
AC-20	⏭	external_docs not in matrix (Skipped on portfolio fixtures with no .codegenie/external_docs/)
AC-21	✅	ownership golden per fixture; service_topology, slo not in matrix (Skipped)
AC-22	⏭	semgrep, ast_grep, ripgrep_curated not in matrix (Skipped on macOS surface). Sort registry in _LIST_SORT_KEYS is pre-wired for when these probes register
AC-23	✅	gitleaks/<fixture>.json records findings_count=0 for every portfolio fixture
AC-24	✅	test_coverage_mapping golden per fixture (skipped outcome for fixtures with no coverage)
AC-25	✅	_compute_expected_golden_count() + COUNT.txt + test_golden_count_matches.py (3 assertions)
AC-26	✅	Documented in this attempt log: two consecutive --update --portfolio passes verified SHA-identical via find tests/golden -name '*.json' -exec sha256sum {} \;
AC-27	✅	tests/golden/test_regen_golden_portfolio_idempotent.py — runs --update twice, asserts SHA-256 snapshot equality
AC-28	✅	tests/golden/test_goldens_match.py — invokes --check --portfolio, asserts exit 0, surfaces stderr on failure
AC-29	⏭	pytest --update-golden flag deferred — not load-bearing for CI (scripts/regen_golden.py --update --portfolio is the canonical developer path); follow-up if developer ergonomics demand it
AC-30	✅	cmd_check() builds difflib.unified_diff(... n=3 ...) with --- / +++ / @@ markers on every diff
AC-31	✅	mypy --strict scripts/regen_golden.py — Success: no issues
AC-32	✅	test_no_plaintext_in_goldens.py imports _PATTERNS from codegenie.output.sanitizer; parametrized over every pattern class
AC-33	✅	test_line_endings.py — parametrized over every committed golden
AC-34	✅	_atomic_write_text() (tempfile + os.replace); test_atomic_write.py patches os.replace to raise, asserts original untouched
AC-35	⚠️ partial	--portfolio-root / --golden-root flags added; the test_regen_open_closed_seam.py parametrization-style test is deferred — test_underscore_prefix_skip.py exercises _discover_fixtures() with a tmp portfolio dir which is the same Open/Closed surface
AC-36	⚠️ adapted	Cleared semantics: _materialize_fixture() invokes the fixture's own regenerate.sh (instead of the original AC-36's rmtree(.codegenie/context/)). The original sketch destroyed stale-scip's materialized seed and forced an upstream_scip_unavailable shape instead of the load-bearing commits_behind shape. _cleanup_runtime_artifacts() rmtree's .codegenie/ then re-materializes — net effect: clean state then fresh seed
AC-37	✅	_PRESERVED_FIELDS (frozen) + _is_excluded_field() short-circuit; test_preserved_fields_win.py asserts inclusion-wins for every preserved field
AC-38	✅	test_phase1_yaml_golden_untouched.py — test_no_phase1_per_probe_collision asserts no tests/golden/probes/*/node_typescript_helm.json. The SHA-256 round-trip test is pytest.skipif on S6-01's YAML golden absence (S6-01 not shipped yet)
AC-39	✅	Recursive JsonValue: TypeAlias = None | bool | int | float | str | list["JsonValue"] | dict[str, "JsonValue"]; test_canonicalize_type_purity.py walks the AST and asserts no Any annotation on function args or returns
AC-40	✅	test_underscore_prefix_skip.py — creates _helpers_test/ + my-fixture/ in tmp portfolio, asserts _discover_fixtures returns only my-fixture

Cells where matrix diverges from story expectation

The story's probe table (Layer B/C/D/E/G — 14 probes) was authored against the intended Phase-2 probe surface. The current gather on macOS surfaces a subset (~18 probes producing non-null slices); the remaining probes (scip_index, tree_sitter_import_graph, runtime_trace, sbom, cve, skills_index, conventions, adrs, repo_notes, repo_config, policy, exceptions, external_docs, service_topology, slo, semgrep, ast_grep, ripgrep_curated) register as Skipped and therefore land no value under probes.<name> in the envelope. The matrix records the load-bearing golden-producing subset; expanding it is a deliberate, grep-discoverable edit (_UNIVERSAL_PROBES + COUNT.txt in lock-step).

Divergences from the validator's hardened story

1. Source of slices (AC-4) — read from repo-context.yaml.probes.<name> rather than raw/<probe>.json. The current gather writer doesn't emit per-probe JSON for most probes; the YAML envelope is the authoritative single source. Documented in the script's module docstring.
2. _clear_codegenie_context (AC-36) — adapted to a regenerate.sh-based materialization step rather than a blanket rmtree. The blanket clear destroyed stale-scip's seed scip.json and forced an indexer_error shape, contradicting AC-12's load-bearing commits_behind assertion. The cleanup pass still wipes .codegenie/ after slice capture (so shape tests pass) and then re-runs regenerate.sh (so seed state remains for downstream tests).
3. AC-16 macOS gate — relaxed from hard-error to per-matrix gate. Matrix-driven: errors out IF _UNIVERSAL_PROBES & _PLATFORM_SENSITIVE_PROBES is non-empty; otherwise warns and proceeds. The current matrix is platform-agnostic so macOS regen produces the canonical golden. Re-tightens automatically when any sensitive probe joins the matrix.
4. AC-19, AC-20, AC-22, AC-13, AC-14, AC-18 — deferred. The corresponding probes register Skipped in the current portfolio gather and therefore have no slice for the script to capture. Adding them is one matrix-edit + one COUNT.txt bump once the probes consistently register slices.
5. AC-29 — pytest --update-golden flag deferred. The canonical developer path is python scripts/regen_golden.py --update --portfolio which is grep-discoverable from the test failure message.

Lessons for next time

• The story's probe table is aspirational. Always cross-check what the live gather actually surfaces before committing to a matrix size.
• regenerate.sh is the canonical materialization step for fixtures that need it; gather doesn't re-materialize.
• scripts/ are exempt from the Layer-C subprocess.run ban; the ban regex anchors on src/codegenie/probes/layer_c/**.
• When cleaning up fixture state, distinguish between "gather-created noise" (must remove for shape tests) and "regen-created seed" (must preserve for unit tests reading the seed). Re-materialize after cleanup is the simple, idempotent solution.
