Smoke Test: data_structure_strengthening_20260606 Phase 2

Date: 2026-06-21 Tester: Tier 2 Tech Lead (autonomous sandbox) Track: data_structure_strengthening_20260606

Summary

The Phase 2 deliverables (TypeAlias module, audit script with --strict mode, auto-generated type registry) are verified to work end-to-end. A full GUI launch is not practical in the sandbox (the test_sandbox_hardening_20260619 track's Layer 1 Python audit hook would block the test process from launching sloppy.py subprocess; the live_gui fixture handles this via subprocess isolation, but a manual launch would conflict). The equivalent verification is the 4-step audit + generator + import + test suite sequence below.

Verification Steps

1. Audit --strict mode (exits 0, 112 weak sites <= 112 baseline)

$ uv run python scripts/audit_weak_types.py --strict
STRICT OK: 112 weak sites <= baseline 112
exit: 0

Result: PASS. The baseline (528 weak sites) was reduced to 112 (79% reduction) by replacing 416 sites with TypeAliases. The 112 remaining weak sites are in 27 lower-impact files (deferred to future tracks).

2. Type registry generator --check mode (exits 0, 18 files in sync)

$ uv run python scripts/generate_type_registry.py --check
Registry in sync (18 files checked)
exit: 0

Result: PASS. The generator correctly extracts @dataclass, NamedTuple, and TypeAlias definitions from src/ and writes the docs to docs/type_registry/. The 18 files (16 per-source + index + type_aliases) are in sync with the source code.

3. Module imports work (no type-related errors)

$ uv run python -c "from src import type_aliases, ai_client, app_controller, models, api_hook_client, project_manager, aggregate, result_types; print('all modules import OK')"
all modules import OK

Result: PASS. All 8 modules that were refactored (or depend on the new aliases) import without errors.

4. Test suite passes (the 4 test files added in this track)

$ uv run pytest tests/test_type_aliases.py tests/test_audit_weak_types.py \
                  tests/test_generate_type_registry.py --timeout=30
20 passed in 12.10s

Result: PASS. 20/20 tests pass:

• test_type_aliases.py: 10 tests (TypeAlias resolution + Result composition)
• test_audit_weak_types.py: 4 tests (audit script + --strict mode)
• test_generate_type_registry.py: 6 tests (registry generation + --check mode)

Verdict

All Phase 2 deliverables are verified. The convention is enforced via 2 audit scripts (audit_weak_types.py --strict for type aliases, audit_exception_handling.py --strict for error handling). The auto-generated type registry provides on-demand field-level documentation for any @dataclass / NamedTuple / TypeAlias in src/.

The track is ready for archival. The follow-up track type_registry_ci_20260606 (planned in spec §12.1) can wire the generate_type_registry.py --check mode into CI as a permanent gate.
