+# Multi-agent 4→7 Upgrade (Session 39 — 2026-05-29)
+
+**Trigger:** Anh main "tham khảo cấu hình 7 sub-agent BVAAU → tăng tốc + chất lượng → budget +50% + thêm 3 agent". Chốt qua AskUserQuestion 2 câu.
+
+## Decision chốt (AskUserQuestion S39)
+
+1. **Implementer split = Backend / Frontend** (KHÔNG domain/infra như BVAAU)
+   - Lý do: SOLUTION_ERP có 2 React FE app riêng (admin + user) + FE mirror SHA256 là pain point chính (Pattern 16-bis 9×). Tách FE specialist → giảm gotcha #53 truncation khi BE+FE cùng spawn (đã gặp 5×). Mỗi spawn nhẹ hơn.
+2. **test-specialist dedicated** = full test layer (2 implementer KHÔNG viết test)
+
+## 7-agent final (color-coded)
+
+| Agent | Color | Scope |
+|---|---|---|
+| investigator-codebase | cyan | INTERNAL SQL/EF/grep/reference mirror |
+| investigator-api | blue | EXTERNAL docs/CVE/lib eval/cross-project |
+| implementer-backend | yellow | .NET Domain+App+Infra+Api |
+| implementer-frontend | orange | FE 2 app cookie-cutter SHA256 mirror |
+| test-specialist | purple | tests/ dedicated xUnit |
+| reviewer | red | adversarial pre-commit + live curl |
+| cicd-monitor | green | post-deploy Gitea + bundle + smoke |
+
+## Adapt KHÁC BVAAU (anh cho phép "không bắt buộc giống")
+
+- **backend/frontend** thay domain/infra (2-FE-app fit)
+- **Giữ 6 skill proven** (BVAAU Phase 0 = 0 skill, codebase rỗng). Investigator extract verdict: BVAAU config = **aspirational template chưa battle-test** (VIPIX guide reference không tồn tại) → SOLUTION_ERP port trục split CÓ CHỌN LỌC, giữ lợi thế 38-session battle-test.
+
+## Port TỪ BVAAU
+
+- Trục split research(2) + implement(2) + quality(3)
+- **+3 RAG MCP** all 7 agent: `search_code` (BM25, prefer over Read full file — tiết kiệm token) + `store_memory` + `list_projects` (2→5 tools). MCP server verified support.
+
+## Token budget +50%
+
+- Prior: ~700K opt / ~1.35M heavy → **Now: ~1.05M opt / ~2M heavy ceiling**
+- Justify: parallel BE+FE+test giảm wall-clock + split nhẹ giảm truncate + test-specialist clear coverage gap backlog
+- Max 20× plan absorbs ~5× comfortable
+
+## Anti-truncation rules (gotcha #53/#54/#55 codified README)
+
+- Brief WRITE agent ≤ 8K (heavy spec ~10K → truncate risk #55)
+- Curate MEMORY pre-spawn nếu > 25KB (#53)
+- Agent entry ≤ 1.5K chars (frontmatter rule mỗi agent)
+- 529 Overload (#54) → em main solo fallback, KHÔNG retry loop
+- Pre-supply reference snippet trong brief nếu cần > 4 reference file
+
+## How to apply (cross-session)
+
+- **CLI restart BẮT BUỘC** sau đổi agent definition (per S27 model:inherit lesson) → registry hot-reload. Verify smoke spawn 3 agent mới.
+- Memory folder rename: investigator→investigator-codebase + implementer→implementer-backend (giữ history). Khi SendMessage flush agent CŨ trước restart → ghi nhầm folder rename → conflict. Wrap session đổi config: em main proxy synthesize, KHÔNG SendMessage flush.
+- Decision tree split-routing: Read internal→codebase, Read external→api, WRITE .NET→backend, WRITE FE→frontend, test→test-specialist.
+
+**Reusable pattern cross-project:** Khi scale multi-agent, split theo TRỤC WORKLOAD THỰC TẾ của project (SOLUTION_ERP = 2 FE app → backend/frontend) thay vì copy nguyên pattern reference project. Reference project có thể aspirational chưa battle-test → verify trước khi port.
