[CLAUDE] Docs: S114 PE multi-NCC per hạng mục closeout (STATUS/HANDOFF/gotcha #81/Mig 65/session-log)

Closeout feature multi-NCC per hạng mục (ship d436af2):
- STATUS/HANDOFF: S114 blurb + CURRENT STATE canonical Mig 64→65 · test 477→486 · gotcha 80→81 · bundle D51OYyGV/BVdssm5S.
- gotcha #81: derived-invariant re-derive sót DELETE writer (DeleteQuote/DeleteDetail) → IsWinner kẹt stale → HĐ giaTri=0 phantom (Bước 4 fable-clone verify bắt; fix helper PeWinnerInvariant test-before).
- ef-core skill: +Mig 65 BackfillPeQuoteIsSelectedAndWinnerInvariant row.
- session log 2026-07-12-S114 + 2 reviewer diary harvest (verify run) + run-trace fold.
- cicd on-behalf record (garble #53 ×5 → em-main-solo deploy verify).

+
+S114 (2026-07-12) close-review PE multi-NCC per hạng mục — winner-truth flip whole-supplier `Supplier.IsWinner` → per-(Detail×Supplier) `Quote.IsSelected` (IsWinner nay DERIVED). Lens refute-fe-test. Verdict NEEDS-FIX (1 MUST).
+
+**CAUGHT MUST (missed writer — S87/S88 cardinality anti-pattern lần 3):** `DeletePurchaseEvaluationQuoteCommandHandler` (`PurchaseEvaluationDetailFeatures.cs:371-397`) KHÔNG re-derive `supplier.IsWinner` sau `Remove(quote)`. Spec A2 liệt kê writer "SelectWinner + UpsertQuote(update+insert) + seed" — **DeleteQuote vắng mặt trong enumeration** → implementer theo spec faithfully nhưng spec sót. Xóa quote IsSelected cuối của 1 NCC qua nút "Xóa" (FE wired `PeDetailTabs.tsx:2897`) → invariant `IsWinner==Any(IsSelected)` VỠ → phantom winner: winnerSupplierNames projection (`where sw.IsWinner`) hiện NCC + `CreateContractFromEvaluationFeatures.cs:56` `winners=Where(IsWinner)` tạo **HĐ giá 0** (giaTri=SUM selected=0, :88-90). Reachable Draft-phase, sống tới DaDuyet.
+
+**Lesson:** cardinality-change grep-consumer PHẢI gồm cả writer XÓA (Delete handler) của field-nguồn, KHÔNG chỉ Select/Upsert. Field-nguồn = `Quote.IsSelected` → mọi path đổi TẬP quote (thêm/sửa/**xóa**) phải re-derive flag phái sinh. Spec-enumeration của writer KHÔNG đáng tin — grep độc lập MỌI handler chạm entity (grep `Remove(.*Quote`/`db.*Quotes.Remove`).
+
+**SHOULD:** (1) derive-invariant test (`PeSelectWinnerClearTests.cs:566`) chỉ cover UpsertQuote INSERT + SelectWinner; KHÔNG cover UpsertQuote UPDATE-path (exclusion `q.Id != existing.Id` :313-316 — subtle stale-DB-read guard) NÊN test-before-fix cũng thiếu DeleteQuote. (2) FE winner-toggle (`:2707`) không gate trên `q` tồn tại → chọn winner NCC chưa nhập giá = silent no-op + toast success sai (BE chỉ flip IsSelected quote CÓ SẴN :433-434).
+
+**Verified SOLID (resisted scrutiny):** FE 2-app byte-identical `ae3788e9` (hash-object khớp). 5 financial-SUM đều `WHERE IsSelected` (winnerQuoteTotal/submit-guard/CCM-threshold/giaTri/budget-B). giaTri A1 bỏ detailsSum single+multi. **Test discriminate THẬT (non-tautology):** threshold-crossing dựng whole-supplier 1.2 tỷ≥ngưỡng vs selected 500tr<ngưỡng; giaTri-subset 300 vs 800(all-quote) vs 2000(budget). SelectWinner derive IsWinner toàn phiếu (giữ winner hạng mục KHÁC). Seed set IsSelected=true (`DbInitializer.cs:1385`) → derive IsWinner đúng, KHÔNG empty-winner regression (concern plan-review cũ đã đóng).

+Verdict **NEEDS-FIX** (1 MUST). Winner-truth đổi whole-supplier `Supplier.IsWinner` → per-hạng-mục `Quote.IsSelected`; IsWinner nay DERIVED == Any(quote.IsSelected).
+
+## Financial SUM axis = CORRECT (đã verify grep độc lập)
+6 SUM site đều key `q.IsSelected` (không sót IsWinner-keyed sum nào toàn `src/Backend`): winnerQuoteTotal `PeFeatures.cs:1188` · currentProposalTotal:920 · prevSelectedTotal:909 · submit-guard `WorkflowService.cs:196` · CCM-threshold:882 (`>= ceoThreshold` boundary GIỮ, đúng) · giaTri per-winner `CreateContract:88`. Grep `IsWinner` toàn BE = CHỈ existence/name-projection (List:186, PeFeatures:637/758, "đã chọn thầu":907) + entity/config/migration — KHÔNG financial-sum. Backfill 2-chiều idempotent + total-preserving. Seed derive + SelectWinner derive + SelectedSupplierId sync đúng.
+
+## MUST — A2 invariant KHÔNG maintain trên DELETE paths
+`supplier.IsWinner == supplier.Quotes.Any(IsSelected)` chỉ re-derive ở SelectWinner/UpsertQuote(ins+upd)/seed/backfill. **DeleteQuote `PurchaseEvaluationDetailFeatures.cs:396` + DeleteDetail:262 (cascade Detail→Quotes, config line118) xóa selected-quote KHÔNG re-derive IsWinner** (cũng không re-sync SelectedSupplierId). Xóa quote-selected cuối của 1 NCC → IsWinner stranded=true, 0 selected. Reachable FE: quote-dialog "Xóa" btn `PeDetailTabs.tsx:2897` (unconditional, mọi existing quote) + xóa-hạng-mục. Hậu quả: CreateContract `:56` winners chứa phantom → HĐ GiaTri=0 cho NCC không-winner + winner-name/existence sai + FE row kẹt (canDelete=`!isWinner && !hasQuotes`:2640 → không xóa được). Self-heal 1-phần: SelectWinner/UpsertQuote kế tiếp re-derive, NHƯNG không đảm bảo trước CreateContract. **0 test** (không test-source nào gọi DeletePurchaseEvaluationQuote/DetailCommand).
+
+## Lesson
+Derived-invariant (IsWinner từ IsSelected) phải re-establish ở **MỌI mutation đổi tập nguồn — kể cả DELETE + cascade-delete**, không chỉ write/select. Acceptance liệt kê maintenance-point (SelectWinner+Upsert+seed+backfill) BỎ SÓT delete = đúng chỗ reviewer phải bắt (S87/S88 class mở rộng: mutation-path miss ≡ read-site miss). Grep write-path field-NGUỒN + đếm MỌI `.Remove(` chạm entity chứa nguồn.
