Backend scaffold history ở `implementer-backend`. --- ## 🆕 S76 (2026-06-19) — PE budget MA TRẬN 3 cột + bảng lưới `` + badge quyền NS (anh Kiệt FDC) - **Part 1 mirror** (fe-user→fe-admin byte-identical, Python difflib slice-region): `PeBudgetSummaryTable` Block A → ma trận 3 cột (DỰ ÁN hiển-thị-only `—` / PRO `canEditPro` / CCM `canEditCcm`). Type `PeBudgetSummary` +`proInitialAmount`+`proAdjustmentAmount` cạnh `proEstimateAmount`(LEGACY). `proMut` body `{proInitialAmount,proAdjustmentAmount,proNote}`. proFull=proInit+proAdj. - **Part 3 mirror:** `PeWorkflowPanel` approver `.join(' / ')` → map từng approver + badge `✎ NS PRO`(amber)/`✎ NS CCM`(sky) gate `a.canEditProBudget/canEditCcmBudget`. Type `PeCurrentApprovalLevelApprover` +2 cờ **CẢ 2 app** (purchaseEvaluation.ts types DIFFER giữa 2 app → sửa cả 2; PeDetailTabs/PeWorkflowPanel byte-identical). - **Bảng lưới (em-main, anh phản hồi "chưa chia cột giống Excel"):** Block A flex→`
` viền ô. `BudgetCell` xếp dọc (input full ô + Lưu dưới). `BudgetNoteRow`→`BudgetNoteCell` (td colSpan=3). **LESSON: flex+gap KHÔNG ra "bảng" — phải `
` viền ô mới giống spreadsheet.** - **cwd-misland:** Part-1 `cd fe-admin` npm build → MEMORY rơi `fe-user/.claude` stray → em-main harvest về + `.gitignore` guard `fe-*/.claude/` (S76). ## 🆕 S73b (2026-06-18) — PE budget "Ghi chú từ CCM" mirror ×2 app (anh Kiệt FDC) Thêm dòng "Ghi chú từ CCM" trong panel TỔNG HỢP NGÂN SÁCH TRÌNH KÝ (`PeBudgetSummaryTable`), mirror y hệt "Ghi chú từ PRO" nhưng gate `canEditCcm` + `ccmNoteText`/`setCcmNoteText` + save qua `ccmMut`. 2 file ×2 app: types/purchaseEvaluation.ts (`PeBudgetSummary` +`ccmNote:string|null` sau `adjustmentAmount`) + PeDetailTabs.tsx (state mirror proNoteText + `ccmMut` body type +`ccmNote` + **2 call-site echo `ccmNote:bs.ccmNote`** Ban hành+Hiệu chỉnh — endpoint `/budget/ccm` ABSOLUTE-SET cả 3 field, thiếu=null=CLEAR + block mới chèn SAU dòng V0/hiệu chỉnh TRƯỚC Ngân sách PRO, group CCM rows). **LESSON xác nhận S73: budget-table region 2 app byte-IDENTICAL → block mới mirror identical (diff awk-PeBudgetSummary + diff sed-region đều IDENTICAL). PeBudgetSummary type block 2 app identical (KHÁC PeDetailBundle Color-records divergence) → an toàn edit cùng content.** Build PASS ×2 (admin 1945mod `index-CCPIU9Wr.js` / user 1934mod `index-j5Zh9w96.js`, 0 TS err). NO ambiguity, full precedent. KHÔNG đụng BE (DTO `ccmNote` + endpoint body = em-main song song). --- ## 🎯 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, 3× proven) Single-page multi-kind CRUD URL `:kind` param + `Record` + renderField switch FieldType. Reuse: HrmConfigs (S35) + WorkflowApps (S38) + HrmConfigs +2 kind (S51). ADD-KIND playbook: union type + KIND_CONFIG entry + KINDS array + renderCells branch (before fallback) + import icon — `:kind`-driven page = NO new App.tsx route. ### 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 `
` ## ✅ 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) - **2026-06-17 (Văn phòng số "Bảng điều khiển" — mirror fe-user→fe-admin + 4-place wiring ×2 app):** Mechanical mirror+wire step (frontend-designer built in fe-user, em main chốt UX). (A) **index.css SYNC** prereq: fe-admin STALE pre-S66 → `cp fe-user/src/index.css fe-admin/` (no admin-only class to merge — utility sets identical, chỉ S66 gotcha-66 diffs: h1-h4 `#0b1220`/wt700 + .label-eyebrow brand-600 + accent palette comments) → SHA256 `e8631471…` identical. (B) **Mirror 4 file** `cp` user→admin SHA256 IDENTICAL: ui/PageHeader `6ff5303f…`(Văn-phòng-số richer header — eyebrow/icon/accent/breadcrumb, NOT @/components/PageHeader constrained one), ui/KpiCard `f8042ade…`(clickable filter chip a11y role=button), ui/WidgetCard `9221cbed…`(gotcha66 gradient header `text-white!`), pages/office/OfficeDashboardPage `c6d9dc08…`(composes 3 ui over EXISTING hooks, NO new API). All `@/` imports + Button/api/cn + types/{proposal,workflowApps,meeting} đã có ở fe-admin → 0 import fix. (C) **4-place ×2 app:** page(mirror) + App.tsx import+`` (NEW `/office/` prefix convention — page file ở pages/office/, không xung đột; flat office routes giữ nguyên) + menuKeys `OffDashboard:'Off_Dashboard'` (mirror BE MenuKeys.OffDashboard, đặt sau `Off` trước `OffDanhBa` đúng thứ tự BE) + Layout staticMap `Off_Dashboard:'/office/dashboard'` (4th place gotcha#50, trước Off_DanhBa). Leaf admin auto via BE All[]. Build PASS ×2 (user 1934mod `index-BYj_ew5Q.js`, admin 1945mod `index-Cn1flmn6.js`, 0 TS err). CSS @import-order warning + >500KB chunk = pre-existing.
