[CLAUDE] Docs: S44 monthly drift audit + AI_INFRA bundle 06-01 adopt

Cadence audit (2026-06-01), docs-only -> CI-skip. investigator-codebase
drift scan (ground-truth from disk) -> em main patch. No code touched,
154 test unchanged.

Drift fixes (42 count corrections): 40->42 mig, 84/59/55/47->91 tables,
130/111->154 test, 52/49->56 gotcha across CLAUDE.md, docs/CLAUDE.md,
ef-core-migration + dependency-audit skills, schema-diagram, database-guide.
schema-diagram migration table extended Mig 17-42; ef-core history Mig 27-42;
detailed-section gap (Mig 27-42 modules) flagged explicit (deferred, not silent).

AI_INFRA bundle 06-01 (federated, full scope):
- A: RAG T1/T2 auto-ack
- C: hygiene 7/7 agent-mem L1 <=16KB; "25KB"->"~30KB tiered" wording x7
- D: #4 self-sustaining adoption-report step -> /session-end Phase 6.3
- E/F: report + ledger -> docs/governance/

Carry-over .mcp.json + BROADCAST-05-29 left untouched (concurrency rule).

 - ⚠️ **Charter v2:** RAG eval + full re-index (`bootstrap.py`, golden set, recall@5) = **AI_INFRA op** (cần VOYAGE_API_KEY). SE KHÔNG tự chạy.
 - SE-side closeout: (a) verify `store_memory` chunk retrievable (1 `search_memory` rerank check); (b) flag drift/staleness lên AI_INFRA nếu `last_indexed` lag nhiều; (c) báo cáo broadcast nếu adopt infra change.

+- Surface report cho anh main relay AI_INFRA (1 lần báo = ACK+executed+evidence). Em main `/session-start` kế watch + double-check → cơ chế 2 chiều tự duy trì.
+- Session KHÔNG adopt infra gì → ghi "N/A (no infra adoption this session)".
