+**Commits:** 7 commits từ `f568945` (turn 6) → `ae1814c` (turn 12)
+**Scope:** FE polish UX iteration + infrastructure setup multi-agent
+
+## Tổng quan 7 turn
+
+| Turn | Topic | Commit | Files |
+|---|---|---|---|
+| 6 | Manual budget "Nhập tay" — drop tên field + VND format | `f568945` | 6 (3 fe-admin + 3 fe-user mirror) |

+| 11 | Responsive cho laptop màn hình nhỏ (sidebar + workspace + padding) | `6e338f7` | 6 (Layout + PE detail + workspace × 2 app) |
+| 12 | Setup multi-agent infrastructure (3 sub-agents) | `ae1814c` | 7 (4 agent .md + 3 MEMORY.md seed) |
+
+(Turn 7 menu visibility Mig 27 đã có session log riêng `2026-05-11-1700-menu-visibility-mig27.md`. Turn 1-5 đã có `2026-05-11-1100-pe-ui-restructure-s20.md`.)
+
+## Turn 6 — Manual budget "Nhập tay" drop tên field (`f568945`)
+
+User screenshot: chế độ "Nhập tay (không link)" Section 2 b. Ngân sách vẫn còn input "Tên (vd Tạm tính T11/2025)" cùng số tiền. User chỉ cần nhập số tiền.
+
+3 file × 2 app = 6 file FE update:
+- `PeDetailTabs.tsx` BudgetFieldRow (Section 2 detail editor)
+- `PeWorkspaceCreateView.tsx` (workspace mode "new")
+- `PeHeaderForm.tsx` (Create/Edit header page)
+
+Mỗi file:
+- Drop Input "Tên ngân sách" UI khỏi manual mode (state field giữ `''` backward compat — BE save luôn `null`)
+- Manual mode UI giờ chỉ 1 input số tiền (`max-w-xs`) + VND format `1.000.000` + suffix `đ` + hint
+- Helpers `parseVnd` + `formatVndInput` inline mỗi file
+
+PeDetailTabs BudgetFieldRow cleanup thêm:
+- Drop state `manualName` + setter
+- Drop `manualName` từ dirty check
+- Save payload: `budgetManualName: null` luôn
+
+Read-only display (legacy data) giữ `ev.budgetManualName` nếu data cũ có tên (không xóa hiển thị, chỉ ẩn input UI).
+
+## Turn 8 — AddSupplier +Số tiền inline + NCC 5-màu palette + Winner 🏆 (`3ec7b5a`)
+
+User 4 yêu cầu UX NCC grid:
+1. Thêm NCC dialog cho nhập luôn Số tiền báo giá cho hạng mục
+2. Số tiền hiện ra cột so sánh hạng mục (đã có sẵn cột "Số tiền")
+3. Trang trí 3+ NCC khác nhau 3+ màu khác nhau
+4. NCC được chọn (winner) nổi bật hơn
+
+### AddSupplierDialog — sequential POST tạo NCC + Quote
+
+- Thêm prop `detailId?: string` (HangMucCard truyền `detail.id`)
+- Form state `+thanhTien: 0`
+- `showQuote = !!detailId` — chỉ render input "Số tiền báo giá" khi gọi từ HangMucCard
+- Mutation 2 step:
+  1. `POST /purchase-evaluations/{id}/suppliers` → response `{id}` (BE controller `Ok(new {id = newId})`)
+  2. Nếu `detailId + thanhTien > 0` → `POST /quotes` với `purchaseEvaluationDetailId + purchaseEvaluationSupplierId (newSupplierRowId) + thanhTien`
+- Toast: "Đã thêm NCC + báo giá" (có quote) hoặc "Đã thêm NCC" (no quote)
+- Section input "Số tiền" trong card `bg-brand-50/40` + VND format + suffix `đ` + hint "Để trống / 0 → chỉ tạo NCC"
+
+### NCC row 5-màu cycle palette + winner badge
+
+```ts
+const NCC_PALETTES = [
+  'border-l-blue-400 bg-blue-50/40',
+  'border-l-purple-400 bg-purple-50/40',
+  'border-l-sky-400 bg-sky-50/40',
+  'border-l-teal-400 bg-teal-50/40',
+  'border-l-pink-400 bg-pink-50/40',
+] as const
+```
+
+Loop `ev.suppliers.map((s, idx) → palette = NCC_PALETTES[idx % 5]`.
+
+Winner override:
+- `border-l-emerald-500` (thay vì palette stripe)
+- `bg-emerald-100/70` (đậm hơn)
+- `font-semibold + shadow-sm`
+- `ring-1 ring-inset ring-emerald-300`
+- Badge inline "🏆 Trúng thầu" rounded-full bg-emerald-600 text-white
+
+## Turn 9 — Winner revert badge → icon ✓ đậm + hover (`83aae8e`)
+
+User feedback: bỏ badge "🏆 Trúng thầu", revert về icon stick ✓ cũ nhưng đậm hơn + hover.
+
+- Bỏ badge rounded-full
+- Restore `<span className="mr-1 text-base font-bold text-emerald-700">✓</span>` prefix
+- Tên NCC winner đậm: `text-emerald-900`
+- Row hover transition:
+  - Winner: `hover:bg-emerald-200/70`
+  - Non-winner palette: `hover:bg-white/80 hover:shadow-sm`
+  - Smooth qua `transition` class
+
+## Turn 10 — AddSupplier auto-fill master khi chọn NCC (`66551db`)
+
+User: chọn NCC từ dropdown master → auto-load các field đã có sẵn (contactPerson/phone/email/note) vào form.
+
+`AddSupplierDialog` dropdown "NCC (master)" onChange:
+```tsx
+onChange={e => {
+  const picked = suppliers.data?.find(s => s.id === e.target.value)
+  setForm(prev => ({
+    ...prev,
+    supplierId: e.target.value,
+    contactName: picked?.contactPerson ?? '',
+    contactPhone: picked?.phone ?? '',
+    contactEmail: picked?.email ?? '',
+    note: picked?.note ?? '',
+  }))
+}}
+```
+
+Hint "✓ Đã tự điền từ Master — bạn có thể sửa lại nếu cần" text-[10px] text-emerald-600.
+
+Mapping master Supplier → PE.Supplier:
+- `contactPerson` → `contactName`
+- `phone` → `contactPhone`
+- `email` → `contactEmail`
+- `note` → `note`
+
+Skip: `displayName / paymentTermText / thanhTien` (manual, không có trong master). Skip `address` (PE.Supplier không có field tương ứng).
+
+## Turn 11 — Responsive laptop màn nhỏ (`6e338f7`)
+
+User: "giao diện hiện tại chưa đáp ứng tốt cho laptop màn hình nhỏ → Căn chỉnh lại nhé."
+
+Memory `feedback_responsive_laptop_breakpoint.md` capture pattern 4 tầng.
+
+4 fix targeted:
+
+| Fix | Trước | Sau | Gain |
+|---|---|---|---|
+| Sidebar (fe-admin + fe-user) | `w-72` (288px) | `w-60 xl:w-72` | +48px lg |
+| PE Workspace 2-panel | `lg:grid-cols-[320px_1fr]` | `lg:[260px_1fr] xl:[320px_1fr]` | +60px lg |
+| Section padding | `px-5 py-4` | `px-3 py-3 sm:px-5 sm:py-4` | +16px xs |
+| HangMucCard padding | `gap-3 p-3` | `flex-wrap gap-2 p-2 sm:gap-3 sm:p-3` | +8px xs |
+
+Net gain trên laptop 1366px: ~+132px width cho NCC table area.
+
+Behavior phân tầng:
+- **<sm** (mobile): tightest padding
+- **lg** 1024-1279px: sidebar 240px + workspace list 260px
+- **xl+** 1280px+: behavior cũ giữ nguyên (sidebar 288, list 320, padding rộng)
+
+KHÔNG đụng dialog widths / semantic breakpoints lớn / `md` `sm` mobile.
+
+## Turn 12 — Multi-agent infrastructure setup (`ae1814c`)
+
+User paste self-contained template từ NAMGROUP s41-s43 trial empirical-grounded. Pre-flight decision gate **6/6 ✅** → proceed setup.
+
+### Pre-flight checklist
+
+| Question | Status |
+|---|---|
+| Codebase > 10K LOC? | ✅ (59 tables · 27 mig · ~142 endpoints · 34 FE pages) |
+| Project > 6 months? | ✅ (roadmap T1-T13) |
+| Heavy multi-file features regular? | ✅ (per-chunk 5-6 commit/session) |
+| User extend "ngáo threshold"? | ✅ (S20 đã 12+ turn deep context) |
+| 25+ accumulated gotchas/patterns? | ✅ (44 gotchas · 14 memory · 6 skills) |
+| Critical changes adversarial review? | ✅ (UAT live 3 prod domain) |

+### Customizations SOLUTION_ERP
+
+- Skills preload mỗi agent (reuse 6 skills hiện có):
+  - **Investigator:** `contract-workflow` + `permission-matrix` + `ef-core-migration`
+  - **Implementer:** `ef-core-migration` + `permission-matrix` + `form-engine`
+  - **Reviewer:** `dependency-audit-erp` + `iis-deploy-runbook` + `contract-workflow`
+- DB context: `_Dev` runtime + `_Design` ef tooling distinct
+- Test bearer: `admin@solutions.com.vn` (full) + `nv.test@solutions.com.vn` (Drafter UAT scope)
+- Prod UAT: `api/admin/eoffice.solutions.com.vn`
+
+### Windows MAX_PATH pitfall handled
+
+Project path `D:\Dropbox\CONG_VIEC\SOLUTION\SOLUTION_ERP\` = 51 chars + Dropbox-managed → `isolation: worktree` **DROPPED** khỏi `implementer.md` frontmatter (per template Pitfall 1). Em main reviews diff before commit (compensate).
+
+### Memory baseline seeded
+
+3 MEMORY.md có:
+- Patterns proven cross-session (5-chunk discipline, 3-file Mig rule, audit-reuse clone, service hook derived state, FE mirror 2 app, VND format helpers, responsive 4-tầng)
+- 44 gotcha cross-ref
+- Phase 9 UAT iteration mode (skip test per chunk theo memory `feedback_uat_skip_verify`)
+- 5-category Reviewer checklist tinh chỉnh theo SOLUTION_ERP gotcha cluster
+- Tests baseline 81/81 PASS preserve
+
+### Trial workflow
+
+- **Week 1 candidate:** Contract V2 wire (Mig 28+29) mirror PE pattern S17-S19 — pattern proven 1× audit-reuse. ~600+ LOC, 2 mig + Service + Controller + FE × 2 app.
+- **Week 2-3:** Feature wire (Solo em + Inv pre-flight + Rev pre-commit) — phân quyền strict V2 + drop legacy V1.
+- **Week 4:** Evaluate quality vs cost real numbers.
+  - Pass criteria: Rev catch ≥ 2 wire bugs trước commit + time saving ≥ 25% Case 1+2 + Max 20× quota comfortable
+  - Fail: rollback solo, agents archived
+
+### Agent state (chốt session)
+
+3 sub-agents **vừa setup** ở turn 12 — chưa spawn work nào. MEMORY.md seeds-only state. KHÔNG có findings để flush cross-agent learnings ở session này. Trial Week 1 sẽ kick off ở Session 21 với Contract V2 candidate.
