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.
