## S40 (2026-05-29) — Init + consolidation + bulletin adoption + RAG recovery

**10 commit `d2f52ba..37536fd`** (all docs/infra → CI skip). KHÔNG product code/schema.

**Done:**
- ✅ **Init audit 10-mục** — 7-agent live, RAG re-rank PASS, 130 test confirm, state re-grounded từ code.
- ✅ **Doc consolidation** — STATUS 170KB→5.7KB + HANDOFF 224KB→3.4KB (393KB→9KB, full archive `docs/_archive/` zero-loss). Count re-ground: endpoints **211**, FE pages **65** (36+29), menu **~53**, **tables 84 đúng** (DbSet 77 + Identity 7). CLAUDE.md root patch.
- ✅ **Curate 4 agent MEMORY** >25KB→<8.4KB (foundation preserved + git verbatim `d2f52ba`).
- ✅ **AI_INFRA bulletin 2026-05-29 adopt 4/4:** MỤC1 charter v2 ack · MỤC2 **Tiered Memory Policy v1** (L1 HOT ~30KB / L2 archive / L3 RAG, bỏ hard 25KB) · MỤC3 **/session-start + /session-end slash command LIVE** · MỤC4 RAG v1.3 compliant + rag.json extra_corpus slug BUG FIX.
- ✅ **Broadcast AI_INFRA** (adoption + infra retrospective + 5 đề xuất) — file `docs/governance/BROADCAST-OUT-*` + RAG `store_memory` (rerank 0.91-0.96 cross-project discoverable).

**⚙️ NEW slash command LIVE:** `/session-start` + `/session-end` (`.claude/commands/`) — dùng thay paste prompt thủ công.

**⚠️ RAG MCP outage S40:** máy treo full ổ C → MCP rớt nhiều lần. Recovery: **quit hẳn + relaunch FRESH + approve trust `.mcp.json`** (KHÔNG resume — cached config). server.py/env/key/Qdrant verified healthy (lỗi thuần Claude Code client). Memory `[[rag-mcp-recovery-and-concurrency]]`.

**⚠️⚠️ CONCURRENCY CHƯA giải quyết:** session SE **thứ 2 chạy song song** S40 → append "BROADCAST 2" vào `docs/governance/BROADCAST-OUT-SOLUTION-ERP-2026-05-29.md` (**UNCOMMITTED**, M trong git) + `.mcp.json` untracked. Anh main quyết: commit chung / để session kia tự / gộp dup. **TRÁNH 2 session SE cùng sửa repo.**

**⏳ Standing items đã broadcast cho AI_INFRA (infra op):** re-index SE (path fix → 27 memory entries + S38-S40 content) · registry sync · verify auto_reindex hook (last_indexed lag) · **search_code corpus gap** (chỉ index .md, thiếu src/*.cs + fe/*.tsx) · chunk 512 trial 2026-06-16.

**Next S41 (anh main pick) — FOCUS PRODUCT:**
1. **Phase 11 P11-A** — wire ApproveV2 + LevelOpinions 4 module (full 5-agent end-to-end)
2. **Test coverage gaps** — 🟪 test-specialist Gap1 (Holiday UNIQUE CRITICAL) + Gap3 (gotcha #44 ~50 LOC)
3. **Phase 9 Ops** (anh main coordinate: SMTP + rotate creds + UAT)
4. (coord) Giải quyết concurrency: BROADCAST 2 uncommitted + `.mcp.json` untracked
