**Last updated:** 2026-05-29 (Session 41 — RAG corpus cleanup w/ AI_INFRA: exclude `**/`-fix + re-bootstrap 3080→2406 + 5/5 store_memory preserved)

## S41 (2026-05-29) — RAG corpus cleanup (w/ AI_INFRA)

**3 commit `282cbd0` + `e8cbbe5` + (this STATUS/HANDOFF)** — all docs/infra → CI skip. KHÔNG product code/schema.

**Done:**
- ✅ **Exclude fix** `.claude/rag.json` root-anchored → `**/`-anchored (gotcha #10: `node_modules/**`+`docs/_archive/**` không match nested path → 237 node_modules + 22 _archive junk chunks ẩn trong corpus). AI_INFRA cũng fix `find_files` dir-aware host-side (eb9634e).
- ✅ **store_memory reconcile 5/5** trước re-bootstrap (anti-data-loss). Unified at-risk rule: content phải reproducible từ file {exists ∧ matches corpus glob ∧ not excluded} — "file exists" CHƯA đủ (NAMGROUP mất 2 chunk vì .tsx ngoài glob). 3 broadcasts disk-twinned + `16a6b6db` twin-safe + `0307141b` S37-S40 catch-up **promote-to-disk** (anchor `#s37-s40-catchup` là virtual label, KHÔNG phải section thật trong STATUS.md đã tier).
- ✅ **AI_INFRA re-bootstrap** host-side `--config`: 3080→**2406** (−674 junk). Verify Qdrant: node_modules=0 · _archive=0 · manual-marker=0 · user-memory 60 chunks/10 files (slug fix `D--Dropbox-CONG-VIEC-SOLUTION`→`-SOLUTION-ERP`) · catch-up 6 + audit-response 6.
- ✅ **SE post-verify PASS** in-session: `list_projects`=2406 live; promoted catch-up returns **file-indexed** (real heading, not `(manual)`) → twin-safety proven zero-loss.

**⚠️ CLI restart (fresh)** requested by AI_INFRA cho tag-persist (corpus đã serve live in-session).

**⏳ Standing infra backlog (AI_INFRA, non-blocking):** bootstrap glob→0 warn · auto_reindex hook fire · search_code corpus gap (src/*.cs+fe/*.tsx — v0 design call) · registry sync.

**⚠️ Concurrency carry-over (vẫn nguyên — chưa đụng):** `M docs/governance/BROADCAST-OUT-...-2026-05-29.md` (session SE thứ 2) + `?? .mcp.json` untracked. Anh main quyết.

**Next S42 (anh main pick) — FOCUS PRODUCT:** (1) Phase 11 P11-A wire ApproveV2 + LevelOpinions 4 module · (2) Test gaps (Gap1 Holiday UNIQUE CRITICAL + Gap3 gotcha #44) · (3) Phase 9 Ops (SMTP + rotate creds + UAT) · (4) coord concurrency carry-over.

## 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

Pure infra/governance, 1 commit `fd0554a` (docs CI skip). 7 agent: 🟦 investigator-codebase (internal SQL/EF/grep) + 🟦 investigator-api (external docs/CVE/lib) + 🟨 implementer-backend (.NET) + 🟧 implementer-frontend (FE 2 app) + 🟪 test-specialist (tests/) + 🟥 reviewer + 🟩 cicd-monitor. `model: inherit` (Opus 4.8 1M). 5 RAG MCP/agent. Skill re-distribute (README matrix). 2 gotcha NEW: **#54** (529 Overload spawn fail → em main solo fallback) + **#55** (truncation mid-exploration → brief ≤8K + pre-supply snippet).
