[CLAUDE] Docs: Chunk M4 — S23 t3 Plan M wrap: docs + session log + 2 agent MEMORY drift

3 commits Plan M `c2042ef + 508b17a + 4dd6f9c` cumulative:
- M1 (`c2042ef`) BE Service refactor F1.OneLevel/OneStep edge case Bước 1 → reset (0, 1) giữ ChoDuyet (KHÔNG fallback Drafter)
- M3 (`508b17a`) FE × 2 app rename phase=TraLai display label "Trả lại" → "Cần chỉnh sửa lại"
- M2 (`4dd6f9c`) Tests add 2 edge case test 106/106 PASS (+2 từ 104)

Docs update:
- docs/STATUS.md — Last updated S23 t3 + stats 106 test (+2) · 20 memory (2 entry reinforced)
- docs/HANDOFF.md — TL;DR S23 t3 với multi-agent ROI evidence Investigator avoid em main spam refactor
- docs/changelog/sessions/2026-05-15-s23-turn3-plan-m-f1-edge-case.md — Session log đầy đủ

Memory user-level update (2 entry reinforced):
- feedback_per_nv_permission_scope.md — S23 t3 reinforcement "edge case không lùi được KHÔNG fallback role khác"
- feedback_uat_skip_verify.md — Plan L S23 t2 lesson "Service refactor semantic BẮT BUỘC test cùng commit"

Agent MEMORY drift (auto-flush per multi-agent rule §):
- Investigator (.claude/agent-memory/investigator/MEMORY.md) — S23 t2 spawn L2 entry + S23 t3 spawn M0 audit findings
- Reviewer (.claude/agent-memory/reviewer/MEMORY.md) — S23 t3 Plan M cumulative PASS-WITH-NOTES verdict + 2 Minor defer

Reviewer verdict: PASS-WITH-NOTES (26 checks PASS, 0 Major, 2 Minor defer).
- Minor #1: 5-8 inline literal "Trả lại" PE module FE còn (filter / hint / button verb mix) — verb button giữ, filter/hint defer
- Minor #2: Contract + Budget module Phase=98 vẫn 'Trả lại' — Plan M scope PE-only, defer

Stats Plan M chốt:
- 31 mig (no change) · 59 tables · ~145 endpoints · 34 FE pages
- **106 test PASS (+2: F1 OneLevel/OneStep edge case)**
- 47 gotcha · 20 memory (2 entry reinforced) · 6 skills
- 4 sub-agents (1 Investigator pre-flight + 2 Implementer Case 2+3 + 1 Reviewer pre-commit)
- 4 commits Plan M `c2042ef..HEAD` ready push

Pending: CICD Monitor post-deploy verify Plan M

+- **2026-05-15 (S23 t3 Plan M cumulative review, spawn):** Pre-push adversarial verify 3 commits local `c2afef2..508b17a..4dd6f9c` Plan M F1 edge case Bước 1 + Phase=TraLai display rename. Diff cumulative: 26 LOC BE (Service.cs:287-333) + 116 LOC test (1 file, +2 test Fact extend SeedWorkflowAsync helper +2 params optional) + 8 LOC FE (4 file × 2 LOC mirror admin+user). **Verdict: PASS** — wire BE M1 verified hot path 287-333 OneLevel+OneStep edge case replace `Phase=TraLai+clear pointer+return` with `Set pointer (0,1) + summary "không lùi được" → fallthrough SLA reset line 364 → Phase=ChoDuyet preserved from pre-call state (entry guard 75-81 require ChoDuyet để Reject decision)`. ApplyReturnModeAsync caller line 94-100 truyền `evaluation.Phase` (now ChoDuyet) vào LogTransitionAsync → Summary="Chuyển phase ChoDuyet → ChoDuyet" + ContextNote contain "không lùi được" (matches test assert ContextNote.Contain). Drafter mode line 268-275 GIỮ Phase=TraLai semantic (unchanged). Assignee line 335-360 throw nếu không match unchanged. F2 ApproveV2Async + F3 EnsureEditableForDetailsAsync + F4 AdjustBudgetCommand handler — UNCHANGED. Schema integrity: 0 migration mới, Phase enum TraLai=98 còn dùng cho Drafter mode + display label rename only. Security: Admin bypass logic line 252-265 + Reject guard line 81 EnsureCanRejectV2Async + non-Approver block — preserved. Code quality: dotnet build PASS 0 err 2 warn (DocxRenderer pre-existing), dotnet test 106/106 PASS (58 Domain + 48 Infra, +2 từ 104 baseline), npm build admin+user PASS 0 TS err (chỉ chunk size warn pre-existing), no `--no-verify`. Test coverage: 2 Fact mới `ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet` + `ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet` cover OneLevel Step1Lv1 + OneStep Step1Lv2→reset. Assert đủ Phase=ChoDuyet + pointer (0,1) + SLA NotNull + ContextNote "không lùi được". Helper extend +2 params backward compat OK (default false). K7 cascade NO regression — 3 `ApproveV2_SkipToFinal_*` xanh (M1 chỉ đụng F1 ApplyReturnModeAsync, không động F2 ApproveV2Async). Mirror 2 FE app (§3.9): purchaseEvaluation.ts admin+user identical (98:'Cần chỉnh sửa lại' + PeDisplayStatus.TraLai:'Cần chỉnh sửa lại'), PeWorkflowPanel.tsx admin+user identical (2 inline literal "Phase → ..." + "Phiếu sẽ về ..." rename). Anti-fiddle: scope drift 0% — 8 LOC FE đúng spec rename Phase=TraLai display only. Anti-pattern guard: **(1) Stale narrative comment Service.cs:288-289 + 327-328** UPDATED rõ "Plan M S23 t3 — KHÔNG fallback Drafter, phiếu giữ đang duyệt" — không zombie. **(2) Audit log consistency** test+code match "không lùi được" exact. **(3) Backward compat** phiếu UAT prod đang Phase=TraLai do logic cũ — Drafter resume từ TraLai vẫn work line 105-132 (entry point `fromPhase==TraLai → targetPhase==ChoDuyet`). **Minor issues (non-block, recommend fix sau):** **(4) Inconsistent UX literal "Trả lại"** còn ở 8 user-facing locations chưa rename (decision design): PeListPanel.tsx:112 "Bản nháp + Trả lại" filter label, PeWorkflowPanel.tsx:270 button "← Trả lại", 272 tooltip "(Duyệt / Trả lại / Từ chối)", 315 "← Trả lại Drafter sửa", 342 "Chọn cách Trả lại", PeDetailTabs.tsx:152 "chỉ Bản nháp / Trả lại mới sửa", 287 "(trừ khi approver Trả lại)", ApprovalWorkflowsV2Page.tsx:639 "(Trả lại / Edit Section 2 / ...)" — phân biệt **action verb** "Trả lại" (button approver click) vs **phase result label** "Cần chỉnh sửa lại" (Phase=TraLai display in dropdown/badge); spec M3 narrow scope chỉ rename phase result label OK. Em main quyết: giữ action verb hay rename hết. **(5) Inconsistent across module** contracts.ts:29 + budget.ts:20 vẫn `98:'Trả lại'` — KHÔNG trong scope Plan M (PE-only) nhưng inconsistent giữa 3 module nếu Contract/Budget có Phase 98 — bro nếu deploy chung sẽ noticeable. Recommendation: SAFE to push 3 commit Plan M; consider follow-up chunk M4 (optional) rename 5 literal user-facing trong PeListPanel + PeWorkflowPanel + PeDetailTabs để consistent UX semantic mới.

 - **2026-05-14 (S23 t1 Plan K1+K2 cumulative review, spawn):** Pre-K3 adversarial verify Mig 31 schema swap + Service Approver F2 branch. Diff scope: 11 BE files +4093/-83 LOC (Mig Designer 3938 lines dominate). 3 commits chuỗi `eb106f2..56868bf..db66253..364aef6` — pre-A slot label refactor + K1 Domain/Mig/Snapshot/sentinel patches + K2 DTO+Service Approver branch. **Verdict: PASS với 2 Major + 2 Minor issues** — K3 OK proceed nhưng K5 endpoint cleanup nên ưu tiên trước K7 test fix. Wire claim verify: Approver F2 branch placed ĐÚNG vị trí (line 477 AFTER UPSERT opinion line 441-468 + BEFORE advance pointer line 502) — opinion sẽ ghi trước skip terminal, audit log đầy đủ context Bước/Cấp. ApproveV1LegacyAsync skipToFinal guard tại CALLER (line 147-149 trong TransitionAsync branch) thay vì callee — pattern OK, V1 method giữ nguyên signature legacy. Schema sqlcmd verify Dev: 7 Allow* columns ApprovalWorkflowLevels (AllowApproverEditBudget/EditDetails/SkipToFinal/ReturnOneLevel/OneStep/ToAssignee/ToDrafter) + Users.AllowDrafterSkipToFinal dropped (count=0). Snapshot regen clean. EF config HasDefaultValue(false) wire. Mig 31 Up() manual reorder ADD→DROP correct per memory `feedback_ef_migration_backfill_reorder`. **Major issues caught** (Smart Friend guard active — KHÔNG để pass): (1) **Orphan UsersController endpoint zombie** — K1 sentinel commented "K2 sẽ refactor DTO + drop field" nhưng K2 chỉ refactor PE side, KHÔNG động UsersController.SetAllowDrafterSkipToFinal + UserFeatures.SetUserAllowDrafterSkipToFinalCommand + UserDto field. Endpoint PATCH `/api/users/{id}/allow-skip-final` vẫn live nhưng silent NoOp (Task.CompletedTask), admin UI tick → BE swallow → confusion UX. Cần K5 endpoint cleanup chunk (per spec). (2) **Stale Mig 28 comment ApprovalWorkflow.cs:78** — comment cũ "F2 (Drafter skip) đã move sang Users.AllowDrafterSkipToFinal" còn nguyên dù line 107-113 prop AllowApproverSkipToFinal mới. Confuse future dev. **Minor issues:** (3) Comment TransitionPurchaseEvaluationCommand DTO PurchaseEvaluationFeatures.cs:401 "F2 — Drafter skip thẳng Cấp cuối khi trình duyệt" still says Drafter (semantic outdated). (4) ApprovalWorkflowConfiguration.cs:22 stale Mig 28/29 narrative comment chưa note Mig 31. Anti-fiddle audit PASS: K1 18 LOC UserFeatures.cs sentinel patches valid compile-break workaround, K2 4 files within original spec. Anti-pattern reinforced 3×: admin opt-in per slot per-NV (Mig 29 F1+F3 + Mig 30 F4 + Mig 31 F2 — em main lần đầu sai Mig 30 default scope expansion → bro corrected). Production build PASS 0 err 2 warn (DocxRenderer unrelated). Test references K7-pending line 253. No `--no-verify` bypass. Pattern caught: "Transient sentinel pattern" — đặt sentinel + comment commit chunk khác cleanup nhưng chunk đó scope SHIFT → zombie state. Recommend explicit K5 cleanup chunk trước K7 test fix. Cumulative state: 31 mig (+1 Mig 31), 47 gotcha unchanged. Smart Friend guard active.
 - **2026-05-13 (S22 18:00→21:00, no spawn):** Em main solo self-review S22 — Reviewer KHÔNG spawn per UAT mode `feedback_uat_skip_verify`. Em main verify build clean + test pass + npm build × 2 app mỗi chunk (11 commits cumulative). Key validations: (1) Plan E phân quyền strict V2 — actor.UserId scope in List + Detail, Inbox đã strict từ S17, loose UAT clause `|| ApprovalWorkflowId != null` removed. (2) S22+1 V2 actor scope guard BE helper `EnsureCanRejectV2Async` chặn request forge non-approver PATCH /transitions decision=Reject (mirror FE button disable) — defense-in-depth FE+BE pattern. (3) S22+4 AdjustBudgetCommand handler 3-tier scope (Drafter Nháp/Trả lại + Approver ChoDuyet + Admin) — S22+5 refactor ChoDuyet branch dùng `level.AllowApproverEditBudget` flag (admin opt-in per slot) thay default Approver scope (security scope correction per bro feedback). (4) S22+2 Identity password policy enforced ≥12 chars (reject `User@123456` 11 chars outdated). Anti-patterns observed: (a) Default scope expansion mistake S22+4 → S22+5 fix — KHÔNG default expand permission scope without admin tick (per-NV opt-in pattern Mig 29 lesson reinforced); (b) History display field assumption BudgetAdjustSection initial — em assume `PeDetailBundle.changelogs` exists, FAIL TS2339 — pattern verify type fields trước render; (c) PS 5.1 Vietnamese diacritics gotcha #30 reinforced — script `seed-test-users-prod.ps1` first attempt FAIL parser error, ASCII-only discipline. S22+4 attachment view endpoint + S22+4 budget-adjust endpoint chưa qua live curl verify (defer post-deploy — bro UAT direct). S22+5 Mig 30 applied LocalDB Dev + Design via `dotnet ef database update`. New gotcha discovered: #47 paths-ignore agent-memory gap (recommend add to docs/gotchas.md — pending bro decide). Cumulative state: 104 test (+20), 30 mig (+1 Mig 30), 46 gotcha unchanged (gotcha #47 pending), ~146 endpoints (+3), 33 active users. Smart Friend guard still active for future spawn.
 - **2026-05-13 (S21 t3-t5, no spawn):** Em main solo verify via dotnet build + npm build × 2 app + dotnet test suite mỗi chunk. Reviewer KHÔNG spawn — em main self-review per UAT mode `feedback_uat_skip_verify` (skip dotnet test mỗi chunk, vẫn build verify). Gotcha #45 fix self-test 3 regression test (test-before §7). S21 t3-t5 push cumulative 12 commits — CICD Monitor verify post-deploy thay vai Reviewer (deploy ship + bundle hash + schema verify). Cumulative state: 84 test, 29 mig, 45 gotcha, 19 memory entries. Pattern saved cho future review focus: per-NV permission audit (Level table vs User table flag), EF migration backfill SQL injection between ADD-DROP order. Smart Friend guard still active for future spawn.
