provides:
  - v1.5 quality gate passage confirmed: ruff 0 violations, mypy 0 errors, 320 tests green
  - PROJECT.md v1.5 milestone validation section with IDX-08, IDX-09, QUAL-01 marked Validated
  - End-to-end smoke test confirmation: chunk_file dispatches .ts files to chunk_typescript

  - v2 planning (clean baseline to build from)

key-decisions:

# Phase 16 Plan 03: Integration Hardening — Validation Gate Summary

**Zero-violation quality gate confirmed (ruff, mypy, 320 tests) and v1.5 milestone declared complete with PROJECT.md updated marking IDX-08, IDX-09, QUAL-01 as Validated.**

## Performance

- **Duration:** 2 min
- **Started:** 2026-02-24T10:04:33Z
- **Completed:** 2026-02-24T10:06:23Z
- **Tasks:** 2
- **Files modified:** 1 (.planning/PROJECT.md)

## Accomplishments

- Full quality gate passed: ruff exits 0 (zero violations), mypy exits 0 (zero type errors in 54 source files), pytest reports 320 tests 0 failed
- End-to-end dispatch wiring confirmed: `chunk_file("example.ts")` dispatches to `chunk_typescript` and returns 2 chunks (`greet`, `PI`)
- PROJECT.md updated: v1.5 milestone section changed to Completed, all IDX-01–IDX-04 + IDX-08, IDX-09, QUAL-01 marked Validated; milestone validation table added with quality gate evidence

## Task Commits

Task 1 was verification-only (no file changes — quality gate confirmation produced no new files):

1. **Task 1: Run quality gate — ruff, mypy, full test suite** - verification-only, no commit needed (all gates passed, dispatch confirmed)
2. **Task 2: Update PROJECT.md — mark v1.5 IDX-08, IDX-09, QUAL-01 as Validated** - `d50aa54` (docs)

## Files Created/Modified

- `.planning/PROJECT.md` — v1.5 milestone section updated: Active→Completed, all requirements [x]-checked, v1.5 Milestone Validation table added with quality gate evidence

## Decisions Made

- Smoke test used Python API (`chunk_file` dispatch) rather than `corpus index` CLI: the index command requires configured LanceDB sources (corpus.toml), making it unsuitable for a standalone tmp_path test; direct `chunk_file` call confirms dispatch wiring just as definitively
- PROJECT.md format: added explicit `## v1.5 Milestone Validation` table alongside checkbox updates for both human readability and grep-ability

## Deviations from Plan

None — plan executed exactly as written. The alternative smoke test path (Python API via `chunk_file`) was explicitly offered in the plan as an equivalent option to `corpus index`.

## Issues Encountered

- `corpus extract --db` flag not recognised (correct flag is `--output -o`): corrected inline per plan guidance (noted the alternative approach)
- `corpus index` requires configured LanceDB sources: used Python API smoke test path as the plan prescribed as equivalent

## User Setup Required

None — no external service configuration required.

## Next Phase Readiness

v1.5 milestone is complete. All requirements validated. Zero blockers.

Quality baseline for v2 planning:
- ruff: 0 violations across 54 source files
- mypy: 0 errors across 54 source files
- pytest: 320 tests, 0 failed
- TypeScript AST chunking: fully integrated, tested, guarded (size + ImportError fallbacks)
