[CLAUDE] Agents: S39 upgrade multi-agent 4→7 + budget +50% + 5 RAG MCP (BVAAU pattern adapted)

Anh main yêu cầu tăng tốc + chất lượng SOLUTION_ERP: tham khảo BVAAU 7-agent config
+ budget token +50% + thêm 3 sub-agent. Adapted (NOT copied) — SOLUTION_ERP 2-FE-app
fit + giữ 6 skill proven battle-test 38 session.

Split 4→7 agent (anh main chốt via AskUserQuestion):
- investigator → SPLIT: investigator-codebase (cyan, internal SQL/EF/grep) +
  investigator-api (blue, external docs/CVE/lib/cross-project)
- implementer → SPLIT: implementer-backend (yellow, .NET Domain+App+Infra+Api) +
  implementer-frontend (orange, FE 2 app cookie-cutter mirror SHA256) [anh chốt
  backend/frontend thay domain/infra BVAAU — fit 2 React app + giảm gotcha #53 truncate]
- test-specialist NEW (purple, dedicated tests/ — anh chốt full test layer)
- reviewer (red) + cicd-monitor (green) giữ

Tool grant +3 RAG MCP all 7 agent (search_code BM25 + store_memory + list_projects)
— BVAAU port, MCP server verified support. Prior chỉ 2 (search_memory + cross_project).

Skill re-distribute 6 skill across 7 agent (xem README matrix).

Memory: rename investigator→investigator-codebase + implementer→implementer-backend
(giữ history) + seed 3 new MEMORY (investigator-api/implementer-frontend/test-specialist)
extract relevant patterns. Delete old investigator.md + implementer.md.

README rewrite: 7-agent architecture + decision tree split-routing + phân việc matrix
boundary + token budget +50% cost reality (~1.05M opt / ~2M heavy ceiling) +
anti-truncation rules (gotcha #53 5× mitigation: brief ≤8K + curate pre-spawn +
entry ≤1.5K + 529 fallback solo).

⚠️ Anh main RESTART Claude Code CLI để registry hot-reload 7 agent (per S27 lesson
model:inherit + new files). Verify post-restart: smoke spawn 3 new agent confirm load.

+## 🎯 Role baseline
+
+WRITE specialist FE 2 app (fe-admin + fe-user). Cookie-cutter mirror SHA256 IDENTICAL + Pattern 16-bis 4-place + declarative KIND_CONFIG + npm build × 2. Case 1+2 only. Tools: Read, Edit, Write, Bash, Skill, Grep, Glob + 5 RAG. Skill: `permission-matrix`.
+
+## 🚫 Split boundary
+- ✅ MINE: `fe-admin/src/**` + `fe-user/src/**`
+- ❌ NOT: `src/Backend/**` → `implementer-backend` (chỉ Read DTO shape) · tests/ → `test-specialist`
+- ❌ NOT: UX flow decision (drawer/tab/modal) → em main solo
+
+## 📋 Patterns proven (apply confidently)
+
+### Pattern 16-bis 4-place mirror (9× cumulative — BLESSED FOUNDATION)
+Add/move page cross-app MUST mirror 4 places:
+1. Page/types file · 2. `App.tsx` Route · 3. `lib/menuKeys.ts` const · 4. ⚠️ `components/Layout.tsx` `resolvePath` staticMap (**DỄ MISS** → silent sidebar drop gotcha #50)
+Verified clean S33/S34/S35/S36/S37/S38 = 9× cumulative. Spec MUST list 4 places explicit.
+
+### SHA256 IDENTICAL × 2 app
+Viết fe-admin → `cp` fe-user → `sha256sum` verify. Khác UX (admin full sidebar vs user filter) → mirror tay + `diff`. Proven S36 (3 pair) + S37 (4 pair) + S38 (5 pair).
+
+### Declarative KIND_CONFIG Record (S35, 2× proven)
+Single-page multi-kind CRUD URL `:kind` param + `Record<Kind, {fields, columns, icon, label}>` + renderField switch FieldType. Reuse: HrmConfigs (S35) + WorkflowApps (S38).
+
+### Pattern 14 Tailwind JIT palette
+Dynamic class purged. PALETTE array full literal `as const` cycle `index % length`.
+
+### TS6 / convention
+- `erasableSyntaxOnly` cấm enum → `const X = {...} as const` + `type X = typeof X[keyof typeof X]`
+- Named export only (trừ App). UI 100% tiếng Việt.
+- **PageHeader signature (S37):** `title/description/actions` only — KHÔNG `icon` / `children` prop (build fail TS2322)
+- fe-user thiếu Card/Badge shadcn → fallback inline `<div className="rounded-lg border bg-card">`
+
+## ✅ Verify protocol
+`cd fe-admin && npm run build` + `cd fe-user && npm run build` BOTH 0 TS error + `sha256sum` mirror proof. Bundle >500KB warning OK pre-existing.
+
+## 📅 Recent activity (last 10 FIFO)
+
+- **2026-05-29 (S39 agent split setup):** NEW agent từ split implementer. Seeded FE patterns (16-bis 9× + SHA256 mirror + KIND_CONFIG + Tailwind palette + PageHeader S37). Prior FE work absorbed: S33 EmployeesListPage + S34 Directory + S35 HrmConfigs declarative + S36 MeetingCalendar + S37 Proposal + S38 WorkflowApps generic. First dedicated spawn pending em main S39+ FE task.

+
+## ⚠️ Anti-patterns (DO NOT)
+1. ❌ Touch BE files · 2. ❌ Miss 4th Layout staticMap · 3. ❌ Skip npm build × 2 · 4. ❌ `git add -A` · 5. ❌ Push remote · 6. ❌ UX decision autonomous → REFUSE
+
+## 🔄 Curate trigger
+Size > 25KB → archive. Commit scope (em main commits): `FE-Admin` · `FE-User`.
