  - Q&A 2 lượt chốt spec (Permission strategy + Matrix layout)
  - Pre-A Investigator findings 5Q + 3 surprises critical
  - Chunk A BE+Layout breakdown (MenuKeys + DbInitializer INSERT-OR-UPDATE-Order
    + Handler filter + Controller pass-through + sidebar widen + revert Plan U truncate)
  - Chunk B FE matrix page + types + App.tsx route
  - Chunk C Reviewer cumulative verdict (PASS 0 blocker)
  - Stats trước-sau + Multi-agent ROI table (~150K total ~25% solo equiv)
  - 4 pattern reinforced cross-project reusable
  - Pending S24+ checklist (7 items)

Agent MEMORY drift (auto-updated by agents + Investigator manual touch):
- .claude/agent-memory/investigator/MEMORY.md +1 FIFO entry S24 Pre-A audit

- .claude/agent-memory/reviewer/MEMORY.md +1 FIFO entry S24 cumulative verify PASS

Stats S24 t1 chốt:
- 31 mig (no Mig mới)
- 59 tables
- ~146 endpoints (+1 GET filter param)
- 35 FE pages (+1 WorkflowMatrixViewPage)
- 111 test (unchanged UAT mode)
- 47 gotcha
- 21 memory user-level
- 6 skills
- 4 sub-agents (3 spawn S24 t1)
- 3 commits Plan AA push remote: ee776d5 (A) + c667802 (B) + this (C)

+- **2026-05-15 (S24, Plan AA Chunk B PASS):** FE user read-only matrix view workflow V2 ghim (Mig 25 IsUserSelectable). 3 file: (1) CREATE `fe-user/src/types/approvalWorkflowV2.ts` (~55 LOC) — subset DTO mirror BE `AwAdminOverviewDto` (7 Allow* flag per Level, 5 record type AwLevelDto/AwStepDto/AwDefinitionDto/AwTypeSummaryDto/AwAdminOverviewDto); (2) CREATE `fe-user/src/pages/pe/WorkflowMatrixViewPage.tsx` (~215 LOC) — useQuery GET `/approval-workflows-v2?applicableType=N&isUserSelectable=true` (em main BE Chunk A đã thêm `IsUserSelectable bool?` param + Controller forward), render table 10 cột Bước (rowSpan) | Cấp | NV duyệt | 7 ✓/— flag cell, header với `title` tooltip mô tả từng cột, 3 state Loading/Error/Empty rõ ràng, badge `Đang dùng` (emerald isActive) + `Được ghim` (amber isUserSelectable Pin icon); (3) UPDATE `fe-user/src/App.tsx` — import WorkflowMatrixViewPage + route `/purchase-evaluations/workflow-matrix` đặt TRƯỚC `/workspace` (URL ordering logical matrix → workspace → new → detail). Verify: `npm run build` fe-user PASS clean 0 TS err, 1907 modules, 2.61s, 1282 KB. Surprise: shadcn fe-user KHÔNG có `Card`/`Badge` (chỉ có Button/Dialog/Input/Label/Select/Textarea) → fallback inline `<div className="rounded-lg border...">` + inline `<span className="rounded-full bg-...">` cho badge (mirror pattern admin Designer). Pattern reusable: **read-only mirror admin Designer page** = drop edit mutations + reuse DTO types (subset) + filter param BE-side (`IsUserSelectable=true` thay vì FE filter). Cookie-cutter 0 (lần đầu pattern). Pattern 5 mirror 2 app KHÔNG apply (fe-admin có Designer riêng — Plan AA scope fe-user only). Pattern 7 admin opt-in 7 Allow* flag wire full render trong table (10 cột total = 3 meta + 7 flag). KHÔNG ops git. Token cost ~14k.

Cookie-cutter 1 file test `PurchaseEvaluationWorkflowServiceReturnModeTests.cs` — 2 sub-tasks: (1) extend `SeedWorkflowAsync` helper +2 params optional `allowReturnOneLevelL1` + `allowReturnOneStepL2` (default false, không phá compat 4 test ReturnMode existing), set vào `l1.AllowReturnOneLevel` + `l2.AllowReturnOneStep` tương ứng — Pattern 3 audit-reuse EXTEND không clone helper; (2) add 2 `[Fact]` test ngay sau test admin bypass OneLevel (line 241) — `ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet` (PE init Step 0 Cấp 1 + actor=a1 + slot Cấp 1 tick AllowReturnOneLevel, build PE inline vì helper `BuildPeAtLevel2` không phù hợp cho Cấp 1) + `ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet` (PE Step 0 Cấp 2 + actor=a2 + slot Cấp 2 tick AllowReturnOneStep, reuse `BuildPeAtLevel2`, OneStep service check `curStepIdx > 0` → fallback ngay không quan tâm Cấp). Assert: Phase=ChoDuyet (KHÔNG TraLai như Drafter mode) + pointer (0, 1) + SLA NotNull + Changelog **ContextNote** chứa "không lùi được" (Summary field cố định `"Chuyển phase {from} → {to}"`, summary từ ApplyReturnModeAsync chèn vào comment qua line 96-99 service → LogTransition `ContextNote = comment`). K7 cascade verify NO regression: 3 ApproveV2_SkipToFinal_* tests still green (M1 edit chỉ F1 OneLevel/OneStep edge case, KHÔNG đụng F2 path `ApproveV2Async`). Verify: `dotnet test SolutionErp.slnx` clean 0 err 2 warn pre-existing DocxRenderer, **106/106 PASS** (58 Domain + 48 Infra: +2 từ 46 baseline post Plan L). 10 ReturnMode-class tests verified individually PASS (4 ReturnMode + 3 ApproveV2_SkipToFinal + 1 Reject_NonApprover + 2 edge case mới).

 - **2026-05-15 (S24, Plan M Chunk M3 PASS):** FE rename Phase=TraLai (98) display label "Trả lại" → "Cần chỉnh sửa lại" cho UAT disconnect fix. Spec scope HẸP (display badge label + status reference) tuân thủ strict: 4 file FE × 2 app = 8 edit total. **2 file types/purchaseEvaluation.ts** × 2 app: `PurchaseEvaluationPhaseLabel[98]` (raw phase badge) + `PeDisplayStatusLabel.TraLai` (display status badge — main user-facing). **2 file components/pe/PeWorkflowPanel.tsx** × 2 app: rename 2 inline literal hardcode "Trả lại" trong F1 dialog tooltip (`Phase → "..."`) + confirm message (`Phiếu sẽ về "..."`) — đây là status display reference, KHÔNG phải action verb. Pattern 5 mirror 2 app strict applied. KHÔNG đụng: (1) action button label `← Trả lại` (verb), (2) F1 mode picker label `Trả về Người soạn thảo` (4 mode action), (3) comments narrative line 62/71/etc giữ rationale dev (rule §6.5), (4) `types/contracts.ts` + `types/budget.ts` Phase 98 'Trả lại' — module Contract + Budget khác PE, ngoài scope M3. Verify: `npm run build` fe-admin PASS clean (0 TS err, 9.40s, 1395 KB bundle unchanged trivial) + `npm run build` fe-user PASS clean (0 TS err, 6.92s, 1275 KB). Diff +4/-4 LOC × 2 = 8 LOC tổng trên 4 file. Token ~9k. Decision tactical: 2 chỗ inline literal PeWorkflowPanel rename để giữ UX consistency với badge label sau rename — KHÔNG drift outside spec vì cùng "status display reference" semantics (badge + tooltip + confirm message phải mirror). Anti-fiddle threshold <20% LOC respected.
