## Archive entries (FIFO chronological — earliest first)

### 2026-05-13 (S21 t3-t5, REFUSED 3×)

Em main classified all 3 turns as cross-stack reasoning chain (BE+FE+test tightly coupled) → REFUSE per criteria #3+#4 (cross-stack > 2 layers, bug fix reasoning chain). Bug fix gotcha #45 = bug + reasoning, F1+F2+F3 = schema design decision, Refactor per-NV = drastic refactor schema + Service + FE × 2 app. All correct REFUSE — em main solo executed. Strict scope criteria validated S21 t3-t5 — REFUSE rate 100% match Anthropic warning "tightly interdependent coding". Cumulative: 84 test, 29 mig, 45 gotcha. Pattern saved future invocation: per-NV permission scope split natural theo role + EF migration BACKFILL reorder pattern.

### 2026-05-13 (S22, REFUSED 100%)

Em main classified ALL S22 work as cross-stack reasoning chain (BE Mig + Service guard + DTO + FE Designer + FE Section + FE types + tests) → REFUSE per criteria #3+#4. Em main solo executed. State chốt S22: **30 migrations** (+1 Mig 30 AllowApproverEditSection1 per-NV F4 flag), **104 test PASS** (+20 từ 84 — gồm PE WF ReturnMode + Draft guard + Reflection-based Authorize policy regression), ~146 endpoints (+3), 46 gotchas unchanged, 33 active prod users (13 cũ + 20 mới S22+2). 7 patterns successfully applied throughout S22 (validated continued effectiveness): Pattern 7 per-NV admin opt-in flag (Mig 30 follow Mig 29), Pattern 2 EF migration 3-file rule, Pattern 8 tách endpoint narrow scope (AdjustBudget vs UpdatePeDraft), Pattern 9 defense-in-depth FE+BE guard pair (S22+1 disable 3 button), Pattern 10 Reflection-based regression test cho Authorize policy (Plan C task 4 #44, 5 test ~50 LOC), Pattern 11 test infra helper cookie-cutter (SeedWorkflowAsync + SeedApproversAsync), Pattern 12 InternalsVisibleTo csproj expose internal helper cho test.

**Mismatches discovered S22:**
1. "Đang trong quá trình duyệt = người điều chỉnh cũng là người duyệt" — em first interpret default Approver scope always allowed → bro corrected per-NV admin opt-in flag (Mig 30). Lesson: clarify default behavior vs admin opt-in TRƯỚC khi default scope expansion.
2. `PE.changelogs` field KHÔNG có trong PeDetailBundle — em first design history display trong BudgetAdjustSection, build FAIL TS2339. Fix: removed history display (defer S23+ via separate fetch endpoint).
3. Dialog `size="xl"` NOT supported — only "sm" | "md" | "lg". Use "lg" cho preview iframe.
4. API auth field `accessToken` không phải `token`. Script `seed-test-users-prod.ps1` lần đầu FAIL 401 sau auth — em fix `$authResp.accessToken`.

### 2026-05-14 (S23 t1, Chunk pre-A PASS)

UI polish slot label Designer Mig 31 prep. File `fe-admin/src/pages/system/ApprovalWorkflowsV2Page.tsx` line 873 replaced `Quyền duyệt NV #{ei + 1}` → `Quyền duyệt {usersList.data?.find(u => u.id === entry.approverUserId)?.fullName ?? 'Chưa chọn NV'}`. Pattern: lookup user fullName từ `usersList` query (Option A — DTO `EditLevelEntry` không có `approverFullName` field, chỉ `LevelDto` BE response có `approverUserName` nhưng edit state dùng `EditLevelEntry`). `usersList` đã in scope ~line 500, pattern lookup `.find(x => x.id === e.approverUserId)` đã dùng tại line 535 cho validation. Cookie-cutter 1 file fe-admin only (fe-user KHÔNG có Designer per Investigator K0 S1). Tailwind classes preserved (`mb-1 text-[10px] font-medium uppercase text-amber-700`). Verify: `npm run build` fe-admin PASS clean 0 TS error, 0 new warning. Bundle 1395 KB (unchanged trivial). Token ~5k.

Mig 31 Up() manual reorder ADD-DROP correct (no BACKFILL). Both DBs Dev + Design applied successful. Build production projects clean 0 err 0 warn. Test compile error `PurchaseEvaluationWorkflowServiceReturnModeTests.cs:253` left for K7 chunk (spec exclude test scope). Pattern `feedback_per_nv_permission_scope.md` reinforced 3× cumulative (Mig 29 F1+F3 + Mig 30 F4 + Mig 31 F2-refactor). UserConfiguration.cs file không tồn tại — User entity configured inline `ApplicationDbContext.OnModelCreating` ~line 86, không có HasDefaultValue cho `AllowDrafterSkipToFinal`, EF picks prop change tự động.

### 2026-05-14 (S23 t1, K7 Chunk F PASS)

Mig 31 Approver F2 service regression tests. Sub-task 1 fix broken Drafter F2 test reference K1 flagged: `PurchaseEvaluationWorkflowServiceReturnModeTests.cs:253` `drafter.AllowDrafterSkipToFinal = true` (DELETE 3 deprecated Drafter F2 tests entire — `SkipToFinal_DrafterAllowed_SetsPointerToFinalLevel` + `SkipToFinal_DrafterDenied_NonAdmin_Throws` + `SkipToFinal_AdminBypass_Succeeds`, semantic deprecated no value). Sub-task 2 add 3 new Approver F2 tests: `ApproveV2_SkipToFinal_AdminTickFlag_SetsPhaseDaDuyet` (happy path — slot Cấp 1 Bước 1 admin tick → Phase=DaDuyet, pointer cleared, opinion + PEA + Changelog logged), `ApproveV2_SkipToFinal_FlagOff_NonAdmin_ThrowsConflictException` (denied — flag off non-admin slot user → throw "chưa được phép duyệt thẳng Cấp cuối"), `ApproveV2_SkipToFinal_FlagOff_Admin_BypassesFlagCheck` (admin bypass — flag off admin role → DaDuyet allowed). Pattern 11 SeedWorkflowAsync cookie-cutter REUSE — created `SeedApproverF2WorkflowAsync` helper (2 Steps × 2 Levels — multi-step verify skip thẳng terminal KHÔNG fallthrough advance pointer next Step), AllowApproverSkipToFinal per-slot param. PE init Phase=ChoDuyet + CurrentWorkflowStepIndex=0 + CurrentApprovalLevelOrder=1 (vs S22 happy path từ DangSoanThao). Add `using Microsoft.EntityFrameworkCore` cho `.ToListAsync()` PEL/PEA/Changelog query. File header narrative line 17-25 REWRITE để track Mig 31 refactor semantic Approver scope ChoDuyet vs Drafter-from-Nháp cũ. Verify: `dotnet build` clean 0 err 2 warn pre-existing DocxRenderer. `dotnet test SolutionErp.slnx` 104 PASS (58 Domain + 46 Infra, 3 deleted + 3 added cancel out, baseline preserved). 3 Approver F2 tests verified individually PASS. Diff +175/-92 LOC trên 1 file. Token ~14k.

### 2026-05-15 (S24, Plan M Chunk M2 PASS)

F1 edge case Bước 1 reset ChoDuyet tests (em main M1 service edit `PurchaseEvaluationWorkflowService.cs` line 287-333 đã DONE — fallback Drafter TraLai → reset (0, 1) giữ ChoDuyet + audit log "không lùi được"). 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). Diff +94 LOC trên 1 test file (test add + helper signature 2 params). Token ~10k. Spec deterministic + 1 file independent + < 1h verified.

### 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.

### 2026-05-15 (S23 t4-t11 cumulative REFUSE — em main solo Plan N+O+P+Q+R+S+T+U)

8 plan consecutive em main solo, 0 Implementer spawn (REFUSE 100% per criteria #4 bug fix reasoning chain + criteria #3 cross-stack tight coupling). **Plan N+O** 5 lookup site discrimination fix cross-stack BE Service + Application + 3 regression test. **Plan P** Controller TransitionPeBody record drop fix tightly coupled FE wire audit (Investigator confirm BE-only scope ~6 LOC). **Plan Q** FE banner mx-5 layout CSS polish 2 app mirror trivial 8 LOC. **Plan R+S+T5** destructive sqlcmd cleanup prod (scripts/plan-r-*.sql + plan-s-*.sql + plan-t5-*.sql + plan-t-backup.sql, 4 files scp + sqlcmd -i, ~720 rows wiped cumulative). **Plan T** DbInitializer DemoSeed:Disabled flag config (Infrastructure + Api appsettings, ~25 LOC). **Plan U** FE sidebar truncate + tooltip 2 app mirror 25 LOC (em main solo CSS Tailwind). 7 strict-scope criteria validated cumulative S23: pattern reusable saved memory user-level — Plan O wire 9 surface points (point 9 lookup discrimination 5 sites enum), Plan P wire 10 surface points (point 10 Controller body record mirror count check), Plan T DemoSeed flag pattern.

### 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.

### 2026-05-15 (S24, Plan AA wrap)

Pattern reusable cho fe-user pages requiring elevated UI surface (audit shadcn fe-user/src/components/ui/ TRƯỚC khi import). Total S24 commits: 7 (a1a910f..ee0902a — 1 spawn Chunk B accepted + 6 em main solo: Chunk A cross-stack + Chunk C docs + 4 polish). Token cost cumulative S24 Implementer: ~14k (Chunk B only).
