# Session 20 turns 6 + 8-12 — PE polish (NCC palette + autofill + responsive) + Multi-agent setup

**Date:** 2026-05-11 (chiều-tối, sau turn 7 wrap-up 17:00)
**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) |
| 8 | AddSupplier +Số tiền inline + NCC 5-màu palette + Winner 🏆 | `3ec7b5a` | 2 (PE detail mirror) |
| 9 | Winner revert badge → icon ✓ đậm + hover transition | `83aae8e` | 2 |
| 10 | AddSupplier auto-fill từ master khi chọn NCC dropdown | `66551db` | 2 |
| 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) |

### Setup created

### 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.

## Memory entries mới (S20)

1. **`feedback_responsive_laptop_breakpoint.md`** (turn 11) — 4-tầng pattern: sidebar w-60 xl:w-72 + workspace 2-panel lg:260 xl:320 + Section padding xs/sm responsive + Card flex-wrap. Decision: phân biệt rõ `lg` vs `xl` cho laptop nhỏ vs desktop.
2. **`feedback_multi_agent_setup.md`** (turn 12) — Decision gate 6-criteria. Anthropic + Cognition hybrid. Implementer ACCEPT/REFUSE strict rules. Windows MAX_PATH pitfall. NAMGROUP s41-s43 ROI curve reference.
