# P6 — Docs, compliance matrix, alpha tag (constitution capstone)

- **Issue:** #606 · **Branch:** `feat/p6-docs-compliance-alpha` · **Lineage:** #542
- **Requirements:** R9 (resident line-count ceiling) + R10 (CONTRIBUTING + compliance matrix + aiguide) + alpha tag

## Delivered (in-repo)

- `framework/CONTRIBUTING.md` — layer model, operator-hygiene/PII prohibition, dedup rule, resident
  budget, **dual-installer parity rule**, adding-a-harness, re-contamination rule, **harness×gate
  compliance matrix** (hook-parity gap marked ⚠️ tracked-v2), known-limitations (§9 residuals), PR checklist.
- `framework/tools/quality/scripts/check-resident-budget.sh` — line-count ceiling over framework-owned
  resident files (CONSTITUTION + AGENTS + each runtime/\*/RUNTIME.md); `--self-test`; replaces the crude
  inline ci.yml loop. Wired blocking in `.woodpecker/ci.yml`.
- Composer unit test (R9) already runs via `pnpm test`; `verify-sanitized.sh` (P1) already wired.

## Verification

- Sanitization gate green (CONTRIBUTING is operator-neutral). Resident-budget self-test + real run green.
- prettier clean. Current resident counts: CONSTITUTION 96, AGENTS 83, RUNTIME max 75 — all < ceiling.

## Remaining

- [ ] `aiguide` reconcile (separate repo `~/src/aiguide` / mosaicstack/aiguide) — consistency pass vs Constitution.
- [ ] Alpha tag `mosaic-vX.Y.Z-alpha` — propose version; Lead cuts after full DoD §8 green + all phases merged.

## Notes

- Alpha DoD (DESIGN §8): all phases P0–P6 merged + CI green. P5 (#605) pending merge after 0.0.38 publish.
- Hook parity (codex/opencode/pi) = tracked v2 gap, documented in the matrix, not closed here.
