🆕 S88 D2 (2026-06-25) — PE multi-winner OUTWARD FE ×2 app (BE đã đổi: create→LIST, list DTO winner names)

3 edit OUTWARD, em-main chốt FE behavior, coord BE (impl-backend đã viết). 2 SHA-pair + 1 type-DIVERGE.

• E1 CreateContractDialog (PeDetailTabs ~:2144): mut type {contractId:string}→{contractIds:string[]} (BE tạo 1 HĐ/mỗi IsWinner). onSuccess: toast `Đã tạo ${res.data.contractIds.length} hợp đồng từ phiếu.` + navigate(/contracts/${res.data.contractIds[0]}) (giữ destination /contracts/${...} của bản single). Dialog GIỮ joined winner-names (:2174) + 1 ContractType-cho-mọi-winner. Bản gốc KHÔNG invalidate → nothing to preserve.
• E2 PeListPanel label (~:168): {p.selectedSupplierName && …✓…} → prefer winnerSupplierNames.join(', ') khi winnerSupplierNames?.length>0, else selectedSupplierName. Giữ ✓ + text-emerald-600. Ternary lặp 2 lần (guard + render) — optional-chain ?.length an-toàn undefined.
• E3 type (DIVERGE 2 file): PeListItem +winnerSupplierNames:string[] sau urgent-flags (anchor isUrgentByPro/Ccm+} byte-identical 2 app → Edit same string ×2, grep-confirm KHÔNG vào inter-app diff, stat giữ 30ins/26del). Create-contract response = inline generic trong PeDetailTabs (KHÔNG named type ở types file) → E3b no-op; contractId:string|null :121/:443 = link-HĐ-đã-gắn field KHÁC, GIỮ.
• SHA256 ×2 pair: PeDetailTabs 9d8120b6…, PeListPanel c97e133d… (cp admin→user, git-diff --no-index IDENTICAL). Build PASS ×2 (admin index-C3j9HaFh.js 2.18s / user index-Ct2cpC7h.js 2.23s, 0 TS err). Pre-existing warn: >500KB + realtime.ts dynamic. NO BE/test touch. LESSON: OUTWARD multi-winner = winnerSupplierNames[] (BE null selectedSupplierName khi ≥2) → FE prefer-list-fallback-single; type DIVERGED ≠ cp → edit-same + verify-not-in-diff (S87+ confirm). Tag [s88, pe-multi-winner-outward, contractIds-list, winner-names-fallback, sha256-2pair, type-diverge-edit-same].

🆕 S87+ (2026-06-25) — FROZEN PE behavior-preserving cleanup ×2 app (em-main chốt, coord BE null-safe)

4 edit PeDetailTabs.tsx (SHA-pair) + 2 wording types/purchaseEvaluation.ts (DIVERGED — KHÔNG SHA-pair, edit identical 2 file).

• E1 HoSoLink clear: HoSoLinkRow.save (~:2020) hoSoLink: hoSoLink || null → hoSoLink.trim() (state đã string nên ??""=no-op; trim ra "" khi xóa). Coord BE UpdatePeDraftHandler null-safe: ""=CLEAR, null/omit=PRESERVE, val=set (fix data-loss xóa link khi edit header). GUARD: InfoTab.save (:817) + PeHeaderForm PUT body GIỮ OMIT hoSoLink (omit=preserve = đúng fix) — verify KHÔNG thêm.
• E2 #70 stale-echo guard: 2 ô PRO adjustMut (row3 NS-kỳ-này :1548 + row8 GT-còn-lại :1649) chỉ saving={adjustMut.isPending} → || peFetching (replace_all đúng 2 occ; peFetching computed :1268). Sibling ccmPeriod/proPrice/ccmPrice/proMut/ccmMut đã có. Chống fast-double-save clobber stale ev.* (2 ô share 1 absolute-set mut cross-echo).
• E3 stale comment :2507: "AddItemDialog giữ (dead)…" → đã xóa (grep chỉ comment match; live = DetailDialog). Sửa thành "nút đã bỏ (dialog = DetailDialog)".
• E4 type wording (2 file): previousSelectedTotal/currentProposalTotal inline cmt "của SelectedSupplier" → "NCC trúng (IsWinner)" (BE giờ multi-winner). Block 7-dòng byte-identical 2 app → edit same → KHÔNG new divergence (grep-confirm my-line ∉ diff).
• SHA256 PeDetailTabs ×2 = 36292924… (cp admin→user, git-diff empty). PeHeaderForm untouched 987291c1… identical. Build PASS ×2 (admin 1946mod index-CqiQWR8e.js / user 1935mod index-Cp0DuKFQ.js, 0 TS err). Pre-existing warn: @import CSS + >500KB + realtime.ts. NO BE/test touch. LESSON: type files DIVERGED (S76/S79 color+prose) ≠ SHA-pair → mirror = edit-identical-block + verify-not-in-diff, KHÔNG cp. Tag [s87plus, pe-frozen-cleanup, hosolink-clear-empty, gotcha70-guard, type-diverge-edit-identical].

🆕 S79 (2026-06-19) — PE detail: live thousand-sep + ghi chú giá PRO/CCM + typo (×2 app)

3 task presentation+wiring PeDetailTabs.tsx (+PeWorkspaceCreateView.tsx typo). BE thêm note body song song; FE chốt UX rồi.

• A live phân cách: chỉ 2 comp thiếu sep — VndInlineEdit (~990) + BudgetCell (~1100): đổi onChange value.replace(/[^\d.]/g,'') → formatVndInput(parseVnd(e.target.value)) (format-on-keystroke, reuse helper module-level :51/52). Dialog money inputs (2111/2555/2645) ĐÃ dùng formatVndInput/parseVnd sẵn → no-op. KHÔNG đụng phone(tel)/%/qty.
• B ghi chú giá: SuggestedPriceRows (~1509) — proPriceMut body {minPrice,maxPrice,note} + ccmPriceMut {ccmPrice,note} (absolute-set 3-field S74). 3 call-site giá echo note:ev.*SuggestedPriceNote. State proNoteText/ccmNoteText (useEffect sync ev.*). Textarea+nút "Lưu ghi chú" dưới PRO Min/Max & dưới CCM (gate canEdit; read-only <p> khi có note). hasAnyValue +!!note (early-return không nuốt note-only readonly).
• Type DIVERGE 2 app (xác nhận S76): PeDetailBundle +proSuggestedPriceNote+ccmSuggestedPriceNote sửa CẢ 2 file riêng (sau ccmSuggestedPrice). PeDetailTabs/PeWorkspaceCreateView byte-identical → cp.
• C typo: d. Bản so sánh → d. Bảng so sánh giá PeDetailTabs:1661(<span>) + PeWorkspaceCreateView:278(label). Comment :1712 + PeAttachmentPurposeLabel[4] GIỮ (ngoài spec, không UI).
• SHA256 IDENTICAL ×2 pair: PeDetailTabs 285ebcf9…, PeWorkspaceCreateView 99caed4b…. Build PASS ×2 (user 1935mod index-_axiw6cM.js / admin 1946mod index-BqPYp7Pt.js, 0 TS err).

🆕 S78 (2026-06-19) — PE "focus mode" redesign mirror fe-user→fe-admin (CONVERGE, em-main chốt UX)

Mechanical mirror-step: redesign built+reviewed-PASS ở fe-user, em-main đã chốt UX (focus overlay). fe-admin ONLY, NO BE/schema. 2 file:

• PeWorkflowPanel.tsx PURE-ADDITIVE: +onApproved?:()=>void prop + wasReject const (byte-mirror isReject formula mutationFn) + if(!wasReject) onApproved?.() cuối onSuccess. Trả-lại/Từ-chối giữ overlay; chỉ forward-approve auto-đóng.
• PurchaseEvaluationsListPage.tsx STRUCTURAL port: bỏ 3-panel grid → list-state mx-auto max-w-5xl panel (4-level tree giữ verbatim) + focus-state ?id = fixed inset-0 z-50 overlay slide-from-right (translate-x-full→0, 2× rAF ~200ms) che menu+TopBar, top-strip "← Thu gọn"+title+"Chế độ duyệt" pill, phiếu trái scroll-riêng + panel duyệt phải lg:w-[24rem] xl:w-[26rem] stack <lg. a11y: role=dialog aria-modal, Esc, focus-trap, scroll-lock, backdrop-click, prefers-reduced-motion. selectRow matchMedia-split → setParam('id',id) UNCONDITIONAL; MAIN comp drop navigate (→ useCallback setParam); bottom PurchaseEvaluationDetailPage GIỮ useNavigate (deep-link compat).
• PRESERVE fe-admin props (rule): <PeDetailTabs readOnly={true}> + <PeWorkflowPanel readOnly={!pendingMe} onApproved={closeFocus}>. Tình cờ trùng fe-user → redesign CONVERGE 2 app.
• SHA256 IDENTICAL ×2 pair (khớp tới trailing-newline }\n\n): page 011968bb…, panel 1dc24641…. LESSON: focus-overlay redesign khiến 2 app converge (props trùng) → mirror-step ra file byte-identical, đo bằng diff+sha256sum KHÔNG mắt. Build PASS (1946 mod, index-D6IyFKgP.js, 0 TS err — tsc-b clean trước vite). Pre-existing warning: @import-order CSS + >500KB chunk + realtime.ts dynamic-import. NO ambiguity, full precedent.

🆕 S76 (2026-06-19) — PE budget MA TRẬN 3 cột + bảng lưới <table> + 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→<table border-collapse> viền ô. BudgetCell xếp dọc (input full ô + Lưu dưới). BudgetNoteRow→BudgetNoteCell (td colSpan=3). LESSON: flex+gap KHÔNG ra "bảng" — phải <table> 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).

🎯 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<Kind, {fields, columns, icon, label}> + 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 <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.
