[CLAUDE] Docs: S40 broadcast-out record to AI_INFRA (bulletin 4/4 adoption + findings)

- Persistent broadcast record docs/governance/ (RAG store_memory deferred — MCP disconnected)
- Format per bulletin section 116: checkmark [SOLUTION_ERP] adopted MUC X (commit)
- 4/4 adoption + rag.json extra_corpus bug-fix finding + 3 standing items for AI_INFRA
- Discoverable via cross_project_search after AI_INFRA re-index (docs/**/*.md in corpus)

+# 📤 BROADCAST OUT — SOLUTION_ERP → AI_INFRA — 2026-05-29
+
+> **Re:** Cross-Project Bulletin 2026-05-29 (`AI_INFRA/docs/governance/CROSS-PROJECT-BULLETIN-2026-05-29.md`)
+> **From:** SOLUTION_ERP (em main) · **To:** AI_INFRA (host) + anh pqhuy
+> **Mechanism:** Persistent record (RAG `store_memory` deferred — MCP `rag-unified` disconnected lúc broadcast; file này vào corpus `docs/**/*.md` → `cross_project_search` discoverable sau re-index). Query: `cross_project_search("solution_erp bulletin adoption 2026-05-29", top_k=3)`.

+## ✅ ADOPTION STATUS — 4/4 (Session S40)
+
+- ✅ **[SOLUTION_ERP] đã adopt MỤC 1 — Charter v2** — ack + memory `feedback_aiinfra_charter_v2` (kèm ranh giới §38: CƠ CHẾ RAG→AI_INFRA / content classification→team).
+- ✅ **[SOLUTION_ERP] đã adopt MỤC 2 — Tiered Memory Policy v1** (commit `6f08d1f` + `9f10764`) — README Memory discipline → L1 HOT soft-cap ~30KB / L2 `archive/` on-demand / L3 RAG just-in-time (bỏ hard >25KB). 7 agent MEMORY header + `investigator-codebase.md` agent-def tiered + anti-truncation rule. archive/ đủ 7 agent (3 seed mới `.gitkeep`).
+- ✅ **[SOLUTION_ERP] đã adopt MỤC 3 — /session-start + /session-end** (commit `c8ff5e1`) — `.claude/commands/` 2 file, adapt 7-agent topology + charter v2 (RAG eval/re-index = AI_INFRA op) + SendMessage-N/A harness caveat. 0 placeholder. Live trong skill registry. ⚠️ anh main restart CLI để fully active.
+- ✅ **[SOLUTION_ERP] MỤC 4 — RAG v1.3 COMPLIANT (SE-side)** (commit `9f10764`) — rag.json v1.3 mechanism OK (`auto_reindex_mode=replace` ✅ + contextual flag + chunk decision-log). Golden set 14 ✅ + baseline recall@5=1.000 (S31) ✅ + anatomy 6/6 + Spec A. **BUG FIX:** extra_corpus slug sai → sửa (chi tiết dưới).

+
+## 🐞 FINDING + FIX (gửi AI_INFRA — infra correctness)
+
+**`.claude/rag.json` extra_corpus slug sai** (đã có từ S30 setup): trỏ `D--Dropbox-CONG-VIEC-SOLUTION` (thiếu `-SOLUTION-ERP`) → **27 user-memory feedback entries của SE KHÔNG được index** suốt 10 session. Đã sửa → `D--Dropbox-CONG-VIEC-SOLUTION-SOLUTION-ERP` (`9f10764`, JSON validated). **Cần AI_INFRA re-index để có hiệu lực.**
+
+---
+
+## 📌 STANDING ITEMS — cần AI_INFRA xử (infra op, team không tự chạy per charter v2)
+
+1. **Re-index `solution_erp`** (`bootstrap.py --project solution_erp`, cần VOYAGE_API_KEY) — pick up: (a) extra_corpus path fix → 27 memory entries, (b) content S38-S40 (Proposal/WorkflowApps), (c) docs consolidated S40. SE stopgap: `store_memory` catch-up chunk (rerank 0.867) đã làm khi MCP còn sống.
+2. **Registry drift** `projects.json` chunk_count vs live Qdrant: dh_y_duoc 3,960 vs 15,435 · namgroup 5,786 vs 11,305 · benhvien/ashico/ai_infra lệch nhẹ. Recommend `sync_registry.py` reconcile.
+3. **chunk_size 1500→512 trial** — SE `_decision_log` schedule eval **trial week 3 (2026-06-16)** per v1.3 §12.4. SE KHÔNG đụng (AI_INFRA mechanism). Chờ AI_INFRA chốt sau eval recall@5.

+
+## 🔁 Convergence + Roadmap ack
+- MỤC 2 (Tiered Memory) chuẩn hóa + thay thế Đề xuất #1 (agent-MEMORY tiering) SE broadcast 2026-05-29 turn trước → đồng bộ.
+- MCP→web hosted roadmap: noted, SE giữ setup local, chờ AI_INFRA broadcast endpoint+auth.
