Response shape has `userName` field accessible ✓. **Pre/Post split observed live:** Recent LogTransition entries (`entityType=5`) at 02:31-02:36 have populated `userName` ("Nguyễn Văn Trường", "Bùi Lê Thủy Trà", "Phan Văn Chương") because LogTransitionAsync already sets UserName independently. **The Budget Adjust entry at 02:31:39 `entityType=1` summary="Điều chỉnh ngân sách: tên..." has `userName=""` empty** — this is the EXACT pre-fix Bug 1 evidence: entry logged by old AdjustPurchaseEvaluationBudgetCommandHandler code BEFORE Plan AE deploy (existing stale entry from Run #216 prod time pre-Plan-AE).

Tip commit Chunk A2: 1 test file `tests/SolutionErp.Infrastructure.Tests/Services/PurchaseEvaluationWorkflowServiceReturnModeTests.cs` +7/-2 LOC — 2 Plan M edge case tests (OneLevel + OneStep AtStep1Level1) add `.Where(c => c.Summary!.Contains("Chuyển phase"))` filter trước `OrderByDescending(CreatedAt).First()` để pick LogTransition entry (chứa ContextNote) thay vì Plan AB new Changelog entry (Summary="Đã xử lý Trả lại — ..." no ContextNote, SAME CreatedAt SQLite frozen clock tie-break). Plan AB Chunk A code `cdfd542` KHÔNG bị revert — Bug 1+Bug 2 fix giữ nguyên. Duration ~3m17s (baseline 3-4 min — full pipeline tests + builds + deploy + smoke). Test gate PASS: test_domain 58/58 ✓ + test_infra 53/53 ✓ (2 Plan M tests now PASS — verified live). Build BE + FE × 2 PASS. Deploy NSSM + IIS recycle PASS. **CRITICAL Stage 4c Plan AB cumulative live wire VERIFY 2/2 ✓ (cdfd542 BE + Chunk A2 test fix DEPLOYED via Run #216):**
  - Bug 1 Budget Adjust entry LIVE on PE c6e9 (`3248f2f9-c6e9-43ff-a4ca-067ffecf9f36` — task brief id `c8e9` typo, actual `c6e9`): entityType=1 (Header), summary="Điều chỉnh ngân sách: tên 'Ngân sách mới update thử ccm' → 'Ngân sách mới', số tiền 5,200,000,000đ → 5,300,000,000đ [Approver Bước 2/Cấp 2]", userId=Phan Văn Chương ✓
  - Bug 2 Return Mode entries LIVE on PE c6e9: multiple entityType=5 LogTransition entries với contextNote chứa "Trả về..." text: "Trả về Bước 1 Cấp 2", "Trả về Bước 2 Cấp 2", "Trà xem lại phần so sánh [Trả về Người chỉ định — Bước 1 (Phòng 1) Cấp 2]" (user comment + auto context append pattern Plan AB Chunk A) ✓
  - Stage 4a Auth admin: HTTP 200 token len 468 ✓
  - Stage 4b Smoke 5/5 endpoints 200 ✓ (`/api/purchase-evaluations`, `/api/contracts`, `/api/menus`, `/api/users`, `/api/purchase-evaluations/{id}/changelogs`)
  - **Stage 4d Bundle hash 2/2 ROTATED ✓:** admin `CZdXQ2eo → CrHpBYFM` ✓, user `DCwhhey2 → C3bCWZ90` ✓ — Plan AB cumulative shipped 2 FE PeDetailTabs.tsx changes from Chunk A `cdfd542` (test file commit doesn't change FE bundle; rotate proxy reflects cumulative Plan AB delta from Run #214 baseline since Run #215 deploy never ran).
  - Stage 4e Health live HTTP 200 + Health ready "Healthy" → Mig 31 RefactorSkipToFinalToApproverLevel applied prod unchanged ✓ (Plan AB no schema change as expected).
  - **Pattern saved gotcha #48 RESOLVED (Run #215 lesson):** When introducing 2nd Changelog.Add() in same transaction as existing LogTransitionAsync chain, tests using `.OrderByDescending(CreatedAt).First()` with SQLite frozen-clock get NON-DETERMINISTIC pick. Fix verified working in Chunk A2: `.Where(c => c.Summary!.Contains("Chuyển phase"))` discriminator filter restores deterministic test pick. Pattern reusable for future multi-Changelog.Add in same SaveChangesAsync transaction.
  - **Side benefit Run #215 → #216 catch loop:** CI test gate caught Plan AB tie-break bug BEFORE prod deploy (Run #215 fail = bro UAT spared broken Plan M edge cases). Chunk A2 test-only fix shipped surgically without re-touching BE service code. Demonstrates: test-after pattern UAT mode CAN tolerate Plan M edge case bug for 1 chunk if next chunk lands within minutes (10:13 fail → 10:21 fix = 8 min turnaround). Token cost ~12k.
 - **2026-05-19 10:13-10:15 — Run #215 id=329 sha=`cdfd542` VERDICT=FAIL (S25 t1 Plan AB Chunk A — Changelog visibility fix Bug 1 Budget Adjust + Bug 2 Return Mode). Push range `e23f51c..cdfd542` 1 commit 3 files (1 BE `PurchaseEvaluationWorkflowService.cs` +207/-95 LOC refactor `ApplyReturnModeAsync` + 2 FE `PeDetailTabs.tsx` mirror filter extend). Duration 1m06s (much shorter than ~3-4 min baseline = early test gate fail, deploy stage never reached). **CRITICAL — Test gate FAIL at test_infra:** 51/53 passed, 2 FAIL same root cause:
  - `PurchaseEvaluationWorkflowServiceReturnModeTests.ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet` (line 350)
  - `PurchaseEvaluationWorkflowServiceReturnModeTests.ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet` (line 308)
  - **Error message:** `Expected changelog.ContextNote not to be <null>`
  - **Root cause:** Plan AB Chunk A `ApplyReturnModeAsync` adds NEW Changelog entry at end (line 403-412) for Bug 2 visibility — `EntityType=Workflow + Action=Update + Summary` (NO ContextNote field). After refactor, BOTH ApplyReturnModeAsync (new entry, no ContextNote) AND LogTransitionAsync (line 100, existing entry with ContextNote=comment) are added in same `SaveChangesAsync` transaction. Test fetches `.OrderByDescending(c => c.CreatedAt).FirstAsync()` — with SQLite + frozen test clock both entries get SAME CreatedAt, OrderByDescending tie-break returns Plan AB's Workflow entry (without ContextNote) instead of Transition entry. Plan M edge case tests broken.
  - Test gate stages: test_domain PASS 58/58 ✓ / test_infra FAIL 51/53 (-2 from baseline 53) / build_be NOT RUN / build_fe_admin NOT RUN / build_fe_user NOT RUN / deploy NOT RUN — exit status 1
  - **Deploy NOT shipped:** Bundle hashes unchanged from Run #214 Plan AA baseline (admin `CZdXQ2eo`, user `DCwhhey2`). Mig prod TOP 1 = `Mig 31 RefactorSkipToFinalToApproverLevel` unchanged ✓. Smoke 5/5 endpoints 200 OK (pre-Plan-AB code stable). PE 3248f2f9... changelogs endpoint 200 returns `[]` empty array (PE may not exist or no log entries — endpoint shape OK).
  - **Plan AB Bug 1+Bug 2 fix NOT live** — bro UAT screenshot pre-deploy stale, Plan AB Changelog visibility refactor NOT shipped to prod.
  - **Recommendation em main:** Plan AB Chunk B HOTFIX — choose ONE of 2 approaches:
    1. **Add `ContextNote` to new Plan AB Changelog entry** (line 403-412): set `ContextNote = summary` (the OneLevel/OneStep edge case "không lùi được" string). Plan M tests pass because either entry now has ContextNote. Caveat: ContextNote may duplicate Summary content.
    2. **Skip Plan AB Changelog entry when `comment` would propagate via LogTransitionAsync ContextNote**: only add NEW Changelog for cases NOT covered by Transition entry (vd terminal mode that doesn't trigger LogTransitionAsync). Refactor more conservative, but Plan AB scope says "single uniform log".
    3. **Alternative — fix tests to fetch specifically EntityType=Transition Changelog**: `Where(c => c.EntityType == PurchaseEvaluationEntityType.Transition)` then OrderByDescending → pick the Transition entry deterministically. Tests still verify ContextNote via LogTransitionAsync chain.
  - **Pattern saved gotcha #48:** When introducing 2nd Changelog.Add() in same transaction as existing LogTransitionAsync chain, tests using `OrderByDescending(CreatedAt).First()` with SQLite frozen-clock get NON-DETERMINISTIC pick → favor `.Where(c => c.EntityType == X)` filter or use deterministic order proxy (Id is Guid not sequential — must use insertion-order via explicit ordering column or filter by discriminator). 4 Mode of Plan AB exposes the assumption.
  - **Side benefit:** CI test gate caught this BEFORE prod deploy — bro UAT spared from broken Changelog audit (pre-existing Plan M edge case audit trail would have been broken in prod if test gate skipped per UAT mode). UAT mode skip test-after pattern still RISKY when refactor touches existing code paths with tests.

Run duration 3-4 min baseline. Iter 4/10 poll completion. **CRITICAL Stage 4c — Plan AA wire VERIFY 4/4 ✓:**
  - **Test 1 `isUserSelectable` filter live ✓:** Admin no filter `total_versions=1` (bf31f120 ver=1 active=true ghim=true) — only 1 ghim version exists prod (DemoSeed:Disabled active per Plan T post Run #207). Admin filter `?isUserSelectable=true` returns same 1 ghim version (count <= no-filter). Non-admin token filter ghim returns same payload (types[0].active id=bf31f120 ghim=true name="Quy trình Duyệt NCC") — **HTTP 200, NOT 403**. Gotcha #44 silent 403 fix confirmed: any-auth read OK (S22 t6 fix `[Authorize]` class-level + GetWorkflowsForUserAsync auth filter).
  - **Test 2 Menu Pe_DuyetNcc_WfView present + Order shift idempotent ✓:** Sorted listing matches exact expected sequence: Pe_DuyetNcc Order=1 / Pe_DuyetNcc_WfView Order=2 "Luồng duyệt" / Pe_DuyetNcc_List Order=3 / Pe_DuyetNcc_Create Order=4 / Pe_DuyetNcc_Pending Order=5 + parallel Pe_DuyetNccPhuongAn family Order=6-10 mirror.

 - **2026-05-13 23:25 — Verify S22 chốt cuối cumulative (push range `3d725c4..cc8a7d3` 12 commits) VERDICT=PASS** (S22 chốt — em main spawn cumulative verify cuối S22). Latest CI run #193 id=307 sha=`b04a11a` (S22+5 Chunk B FE) success at 23:16. **Tip commit `cc8a7d3` (docs+4 agent MEMORY.md) → CI SKIPPED via `**/*.md` glob** (all 4 `.claude/agent-memory/*.md` + 4 `docs/**` files match — paths-ignore correctly fires). Spec hypothesis ("gotcha #47 — `.claude/agent-memory/**` NOT in paths-ignore → trigger CI") **disproven for this commit**: `**/*.md` glob matches `.md` files at ANY depth so `.claude/agent-memory/MEMORY.md` DOES match. Run #188 a74e671 trigger anomaly was NOT due to agent-memory path. **Gotcha #47 still useful as PREVENTIVE** for future when adding non-.md state files under `.claude/agent-memory/` (e.g. `.json` state, `.log`) — explicit `'.claude/agent-memory/**'` ignore would future-proof. **Recent runs S22 sequence (12 commits → 11 trigger + 1 skip):** #189 sha=40f64c6 ✓ (S22+1 BE guard) · #190 sha=8185070 **CANCELLED** by concurrency (seed users script superseded by next push within 3 min — normal not a fail) · #191 sha=0e70789 ✓ (rename script) · #192 sha=30d51c8 ✓ (S22+4 FE) · #193 sha=b04a11a ✓ (S22+5 FE — also covers S22+5 Chunk A BE `b079b27` since both pushed batched; Gitea trigger only on push tip). `cc8a7d3` skip = correct (no run 308). **Discovery #3:** When 2+ commits pushed in same `git push`, Gitea Actions evaluates ONLY the push tip's paths against paths-ignore — intermediate commits do NOT each get evaluated separately. So `b079b27` (BE Mig 30) + `b04a11a` (FE Mig 30) pushed together → single Run #193 on tip. Test gate inferred PASS for all 11 trigger runs (each deploy stage succeeded). **Local test verify 104/104 PASS** (58 Domain + 46 Infra = +1 vs Run #188's 103 — S22+1 added 1 BE guard test). **Mig 30 prod confirmed:** sqlcmd TOP 5 = `20260513160703_AddAllowApproverEditBudgetToLevels` TOP 1 (S22+5 wire). **Schema live verify:** PE detail `currentLevelOptions` 6 keys (5 from Mig 29 + 1 new `allowApproverEditBudget`) ✓, AwLevelDto 12 keys including `allowApproverEditBudget` ✓. **Endpoint wire LIVE:** PATCH `/api/users/{id}/allow-skip-final` admin=204 ✓ + act.nv=403 ✓ (Plan D admin-only enforce) · PATCH `/api/purchase-evaluations/{id}/budget-adjust` admin=204 ✓ (S22+4 BE) · GET `/api/purchase-evaluations/{id}/attachments/{attId}/view` 200 + `Content-Disposition: inline; filename="HD- Eoffice.pdf"` ✓ (S22+4 preview). **Plan E strict V2 scope LIVE:** admin pageSize=200 → 17 PE / act.nv pageSize=200 → 0 PE (Drafter strict filter active; act.nv fresh user no PE participation). **Bundle hash rotated 2/2:** admin `Cclc8Uwu` → `CpI5OL8n` ✓ (S22 cumulative FE deploy) / user `B6N5hq3d` → `d064StNa` ✓ (S22+4 + S22+5 touched fe-user — rotation expected). Smoke 5/5 endpoints 200: contracts, pe, users, menus, approval-workflows-v2. **33 active users prod confirmed** (20 role-based new from S22+2 seed + S22+3 rename: act/pp/tp · bod.1/2 · equ/fin/hra/pm/qs nv/pp/tp + 13 pre-existing). All role-based users `isActive=true` + login `act.nv@solutions.com.vn / TestUser@2026` OK with roles `Drafter,Accounting`. **Token caching pattern from Run #188 worked:** 1 admin login + 1 act.nv login total = 2 auth requests cached to `C:\Users\pqhuy\AppData\Local\Temp\*_token.txt` + 8 subsequent endpoint calls reuse token → no 429 rate limit encountered (vs Run #188 hit 429). **Trend:** S22 cumulative 5 turn iteration delivered Mig 30 + 3 new endpoints + scope filter + 20 seed users — 0 deploy regression. Baseline cumulative passes 81→103→104 test grow consistent with feature delivery.

Duration 3m28s (baseline). Path filter: the push tip `a74e671` includes `.claude/agent-memory/**` files (NOT in paths-ignore) + `docs/**` (in paths-ignore) → Gitea evaluated push as CI-eligible (some files OUTSIDE paths-ignore), trigger fired correctly. **Local test verify: 58 Domain + 45 Infra = 103/103 PASS (+19 from S21 84)** breakdown: 23 codegen + 6 PE WF + 7 ReturnMode + 7 DraftGuard + 5 AuthorizePolicy regression. CI deploy succeeded → inferred test gate PASS (deploy only runs if tests pass).

Mig 29 `RefactorAdvancedOptionsToPerLevelAndDrafterUser` still TOP 1 (no new mig in S22, expected). **Plan D wire LIVE:** GET `/api/users` response includes `allowDrafterSkipToFinal` field (boolean), PATCH `/api/users/{id}/allow-skip-final` admin=204 ✓ + nv.test=403 ✓ (admin-only enforced). **Plan E wire LIVE:** nv.test PE list totalCount=8 < admin totalCount=17 (strict V2 scope filter ACTIVE — drafter only sees own + participant PE). Smoke 5/5 endpoints 200: `/api/contracts`, `/api/purchase-evaluations`, `/api/menus`, `/api/approval-workflows-v2`, `/api/users`. **Discovery #1:** Rate limit auth login triggers at ~5 requests/min — HTTP 429. Pattern: backoff 60s + retry. Spread login calls or cache token across endpoints in same agent run. **Discovery #2:** `.claude/agent-memory/**` files are NOT in paths-ignore (only `docs/**` + `**/*.md` + `.claude/skills/**` + `.gitignore` + `scripts/**.md`) → MEMORY.md commits DO trigger CI even when "looks like docs". Spec assumption ("docs commit `a74e671` triggers paths-ignore skip per gotcha #41") was incorrect for this case — `.claude/agent-memory/**` triggers CI.

(2) Return Assignee mode F1 click → "Lịch sử thay đổi" KHÔNG show return action. Audit 5Q: Q1-DB state Prod SSH fail (auth), fallback code inspect. Q2-Budget handler: `PurchaseEvaluationFeatures.cs:379-387` **ĐÃ log changelog** EntityType=Header + Action=Update + summary diff → **code ĐÚNG, likelihood FE filter bug or UAT DB stale**. Q3-Return handler: `PurchaseEvaluationWorkflowService.cs:215-378 ApplyReturnModeAsync` **ZERO changelog log** — 4 mode branches (OneLevel/OneStep/Assignee/Drafter) mutate pointers only, return summary, caller `TransitionAsync:100 LogTransitionAsync` only logs phase transition KHÔNG log mode side-effect. Q4-Schema: `PurchaseEvaluationChangelog.cs` support EntityType=Workflow(5) enum but **ZERO code populate** — schema incomplete missing Kind/ChangeType subtype enum to disambiguate "budget adjust" vs "detail edit" vs "return mode" (all Header/Workflow entity cùng Action.Update). Q5-FE: Query handler `ListPurchaseEvaluationChangelogsQueryHandler:1050-1064` **KHÔNG filter logic** — returns ALL entities. FE query component unknown (fe-user source not easily searchable) but **likely filter EntityType == (Supplier|Detail|Quote)** omit Header+Workflow → Bug 1 Budget (Header type) hidden, Bug 2 Return (Workflow type unlogged vậy). Root cause B1: FE filter skip Header updates OR Schema gap (Header.Update collision: budget vs section 2 edit). Root cause B2: Handler **intentionally skip logging** (no companion audit table like PurchaseEvaluationApprovals for return history). Fix path B1: Option A (add Kind enum — 30 LOC schema+handlers) vs B (extend EntityType — 20 LOC) vs C (FE filter conditional show Budget — 10 LOC FE). Fix path B2: Add `db.PurchaseEvaluationChangelogs.Add()` per mode (15-25 LOC 1 file). Cross-ref pattern memory: S23 t3 lookup bug (Level.Order collision per-NV Mig 29) — schema Mig 29 OR-of-N refactor created similar subtype ambiguity. Surprise: `EntityType.Workflow=5` enum value design-only, unused 4+ mig history. Recommendation: B2 fix first (clear win, 1 file BE), then B1 design (schema + cross-module pattern audit Contracts). Token ~28k.

Test coverage: Phase 9 UAT exception accept — test-after default OK. Adversarial deep checks: (1) DbInitializer ToDictionary duplicate key risk → PK constraint trên Key, tree.Add chỉ thêm Pe_DuyetNcc_WfView + Pe_DuyetNccPhuongAn_WfView (2 typeCode distinct) → no in-memory dup. (2) Sidebar widen 1280px responsive verified per task spec (288 sidebar + 992 main fit). (3) Plan U revert clean — 0 remaining truncate class outside Plan AA comments. (4) Mig drift schema: column existed Mig 25, no new mig needed. 2 SaveChangesAsync non-atomic giữa menu seed + label backfill (pre-existing, OUT scope Plan AA). Comment quality: Plan AA marker rõ ràng 8+ sites, no TODO/FIXME zombie. TypeScript: `FlagCell` indexed-access type clever từ Pick 7 keys union — TS happy compile clean. Recommendations defer: (a) enforce admin/non-admin policy filter (current GET cho phép user pass isUserSelectable=false — low risk, audit follow-up); (b) MenuKeys.All[] không cover dynamic Pe_*_WfView nên Admin role không auto grant — OK vì admin dùng fe-admin Designer, NOTE để future audit khi admin cần inspect user-side matrix view.

 # Session 25 — 2026-05-19 — PE History Visibility cumulative fix (Plan AB → AF)
 **Dev:** Claude Opus 4.7 1M (em main + 4 sub-agent spawns Investigator+Implementer+Reviewer+CICD)
 **Duration:** ~5h
 **Base commit:** `e23f51c` (Docs Session 24 wrap)
 **Final HEAD:** `506cada` Plan AF FE userMap fallback
 **Total commits S25:** **7** (`cdfd542`, `8c05947`, `a734bf2`, `25837b6`, `0aaf2df`, `9ea62be`, `506cada`)
 **CICD Runs:** **7** (#215 FAIL test gate → #216-#221 ALL PASS post-fix)
 ## 🎯 Trigger session
 Bro UAT 2026-05-19 sau S24 Plan AA deploy phát hiện 2 bug critical phiếu **PE/2026/A/032** (`3248f2f9-c6e9-43ff-a4ca-067ffecf9f36`):
 **Bug 1 — Budget Adjust không show "Lịch sử thay đổi":**
 - Bro click "Điều chỉnh ngân sách" 2× (5.300.000.000 → 5.200.000.000 đ)
 - Section "Lịch sử thay đổi" empty placeholder "Chưa có lịch sử trả lại / gửi duyệt lại"
 **Bug 2 — Trả lại Người chỉ định không log:**
 - Bro role Approver Phan Văn Chương click "Trả lại Người chỉ định" → Bùi Lê Thủy Trà
 - Section "Lịch sử thay đổi" KHÔNG show entry return assignee
 Sau Plan AB deploy bro phát hiện thêm 4 issues UAT iterative — em main solo 5 follow-up plans (AC→AF) cross-stack reasoning.
 ## 🌳 Plan execution 7 commits Plan AB → AF
 ### Plan AB — Bug 1 + Bug 2 root fix
 #### Investigator pre-flight audit (🟦 Investigator, ~28K)
 5Q audit confirm root cause:
 | Q | Finding |
 |---|---|
 | Q1 DB state Changelogs cho PE | SSH auth fail, fallback grep code BE |
 | Q2 BE AdjustBudget handler | `PurchaseEvaluationFeatures.cs:379-387` ĐÃ log `EntityType=Header + Action=Update + Summary="Điều chỉnh ngân sách..."` ✓ |
 | Q3 BE ApplyReturnModeAsync | line 215-378 **ZERO** `Changelog.Add()` cho 4 mode. Caller `TransitionAsync:100` chỉ log phase transition qua `LogTransitionAsync` ❌ |
 | Q4 Schema PurchaseEvaluationChangelog | `EntityType` enum {Header=1, Supplier=2, Detail=3, Quote=4, Workflow=5, Attachment=6}. Missing Kind discriminator (Header+Update collision Budget vs Detail) |
 | Q5 FE filter HistoryTab | Hypothesis FE filter omit Header+Workflow types (unconfirmed Investigator scope) |
 **Conclusion:**
 - Bug 1: BE log OK + FE filter strict TraLai-only loại Header+ChoDuyet
 - Bug 2: BE Service hook ROOT GAP — KHÔNG log Changelog cho 4 mode return
 #### Em main verify FE filter logic
 `PeDetailTabs.tsx:2037-2046` HistoryTab filter:
 ```ts
 const PE_PHASE_TRALAI = 98
 const PE_ENTITY_WORKFLOW = 5
 const filtered = (logs.data ?? []).filter(l => {
    if (l.entityType === PE_ENTITY_WORKFLOW) {
        if (l.phaseAtChange === PE_PHASE_TRALAI) return true
        if (l.summary?.includes('TraLai →')) return true
        return false
    }
    return l.phaseAtChange === PE_PHASE_TRALAI  // ← Header Budget Adjust ChoDuyet bị loại
 })
 ```
 Filter chỉ pass khi phase=TraLai. Header Budget Adjust ChoDuyet → loại. Workflow Reject 3/4 mode giữ ChoDuyet → loại.
 #### Plan AB Chunk A — `cdfd542` (🟨 Implementer Case 1 ~12K, 🟥 Reviewer ~22K)
 **BE refactor `ApplyReturnModeAsync`:**
 - Drafter early return (line 282-287) → if/else common path
 - Single `Changelog.Add()` cuối hàm cover 4 mode uniform với `modeName` switch
 - `actorName` resolve via `userManager.FindByIdAsync` mirror `LogTransitionAsync` pattern
 **FE filter relax × 2 app:**
 - ADD `PE_ENTITY_HEADER = 1` + `summary?.toLowerCase().includes('ngân sách')` cho Bug 1
 - ADD `summary?.includes('Trả lại')` Workflow entity cho Bug 2
 - Update placeholder text + comment 5 rule
 3 files +146/-95 LOC. Reviewer PASS 0 blocker.
 #### Run #215 FAIL — gotcha #48 NEW (🟩 CICD Monitor)
 `test_infra` 51/53 PASS, 2 FAIL Plan M edge case:
 - `ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet`
 - `ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet`
 Error: `Expected changelog.ContextNote not to be <null>`
 **Root cause:** SQLite frozen test clock + 2 Changelog.Add() trong cùng SaveChangesAsync → identical CreatedAt → `OrderByDescending.FirstAsync()` non-deterministic → pick Plan AB row (Workflow+Update+ContextNote=null) thay LogTransition row.
 #### Plan AB Chunk A2 — `8c05947` (em main solo)
 Test fix Option A: filter `Where(c => c.Summary!.Contains("Chuyển phase"))` pick đúng LogTransition entry. Plan AB BE code stays clean.
 ```diff
 - .Where(c => c.PurchaseEvaluationId == pe.Id)
 + .Where(c => c.PurchaseEvaluationId == pe.Id && c.Summary!.Contains("Chuyển phase"))
 ```
 111/111 PASS local. Run #216 PASS deploy success.
 ### Plan AC — Bug 3 Lịch sử duyệt missing Trả lại + Vượt cấp
 Bro UAT post Plan AB: "Lịch sử duyệt" panel 6 entries TẤT CẢ "Đã gửi duyệt → Đã gửi duyệt" (Approve only). Trả lại + Vượt cấp KHÔNG hiện.
 **Root cause:**
 - `PurchaseEvaluationApprovals.Add()` chỉ ở Approve branch (line 472 V2 + 660 V1)
 - Reject branch line 75-103 NEVER add row → Lịch sử duyệt missing
 - skipToFinal advance line 532-572 dùng existing line 472 row nhưng comment KHÔNG distinct
 #### Plan AC commit `a734bf2` (em main solo)
 **BE Reject branch add Approval row:**
 ```csharp
 // Capture pre-call (ApplyReturnModeAsync mutates pointer)
 var fromStepIdx = evaluation.CurrentWorkflowStepIndex;
 var fromLevelOrder = evaluation.CurrentApprovalLevelOrder;
 // ... mutate via ApplyReturnModeAsync ...
 // Add Approval row (Decision=Reject)
 db.PurchaseEvaluationApprovals.Add(new PurchaseEvaluationApproval {
    PurchaseEvaluationId = evaluation.Id,
    FromPhase = fromPhase,
    ToPhase = evaluation.Phase,
    ApproverUserId = actorUserId,
    Decision = ApprovalDecision.Reject,
    Comment = $"{fromPos}{comment ?? ""}".Trim(),
    ApprovedAt = dateTime.UtcNow,
 });
 ```
 **BE skipToFinal enrich comment** line 479 `Comment = $"{skipPrefix}[Bước X — Cấp Y] {comment}"`.
 **FE Decision badge × 2 app:**
 ```tsx
 function decisionBadge(decision, toPhase): { label, cls } {
  if (decision === PE_DECISION_REJECT) {
    if (toPhase === 99) return { label: 'Từ chối', cls: 'bg-rose-100 text-rose-700 ...' }
    return { label: 'Trả lại', cls: 'bg-amber-100 text-amber-700 ...' }
  }
  return { label: 'Duyệt', cls: 'bg-emerald-100 text-emerald-700 ...' }
 }
 ```
 Run #217 PASS, bundle rotate × 2 app.
 ### Plan AC2 — Bug FE merge synthetic Reject from Changelog historical
 Bro: "phiếu cũ PE/2026/A/032 ko thể hiện đc lịch sử trả duyệt và gửi vượt cấp ?"
 Plan AC chỉ forward fix — entries pre-deploy chỉ có Changelog (LogTransition), Approval table missing Reject rows.
 #### Plan AC2 commit `25837b6` (em main solo, Option 2A bro chốt)
 FE merge view: ApprovalsTab fetch changelogs + reconstruct synthetic Reject rows:
 - Filter: `entityType=5 Workflow + (summary "→ TraLai"/"→ TuChoi" OR contextNote "Trả về"/"không lùi được")`
 - Parse phase từ Summary regex `Chuyển phase X → Y` → enum map (DangSoanThao=1, ChoDuyet=10, DaDuyet=20, TraLai=98, TuChoi=99)
 - Synthetic ID prefix `syn-{changelog.id}`, decision=2
 - Dedupe: `${approverUserId}-${Math.floor(approvedAt / 5000)}` 5s bucket key
 - Merge sort by `approvedAt`
 KHÔNG DB write, reversible historical recovery. Run #218 PASS, 8 Workflow entries verified.
 ### Plan AD — Bug 4 dual-phase badges gây nhầm
 Bro: "các bước này chưa thể hiện đc là đã gửi duyệt cho ai ? Trả lại cũng vậy (Đã trả lại thì là trả lại chứ hiển thị đã gửi duyệt thì lại gây hiểu nhầm)"
 3/4 mode Reject (OneLevel/OneStep/Assignee) giữ Phase=ChoDuyet → badge `Đã gửi duyệt → Đã gửi duyệt` identical Approve.
 #### Plan AD commit `0aaf2df` (em main solo, Option A bro chốt)
 **Drop fromPhase→toPhase badges entirely.**
 **Add `extractNextTargetHint(decision, toPhase, comment)` helper:**
 ```ts
 // Approve patterns:
 //   "sang Cấp X" → "→ Cấp X"
 //   "sang Bước Y" → "→ Bước Y (Cấp 1)"
 //   "[Duyệt vượt cấp tới Cấp cuối]" → "→ Vượt cấp tới Cấp cuối"
 //   toPhase=DaDuyet(20) → "→ Đã duyệt hoàn tất"
 // Reject patterns:
 //   "Người chỉ định" + Bước/Cấp regex → "→ Trả về Người chỉ định (Bước X Cấp Y)"
 //   "Người soạn thảo"/"Drafter" → "→ Trả về Người soạn thảo"
 //   "không lùi được" → "→ Không lùi được"
 //   "Trả về 1 Cấp"/"Trả về Cấp X" → "→ Lùi về Cấp X"
 //   "Trả về 1 Bước"/"Trả về Bước X" → "→ Lùi về Bước X"
 //   toPhase=TuChoi(99) → "→ Từ chối hoàn toàn"
 ```
 Cleanup unused `PurchaseEvaluationPhaseColor` import. Mirror × 2 app §3.9. Run #219 PASS, bundle rotate × 2 app. **Gotcha #49 NEW**.
 ### Plan AE — Bug 5 Changelog UserName show "Hệ thống"
 Bro: "chỗ điều chỉnh ngân sách em bắc luôn user nào điều chỉnh luôn em nhé"
 Audit phát hiện systemic gap — 9 `Changelog.Add()` sites trong PE features MISSING UserName field.
 #### Plan AE commit `9ea62be` (em main solo, preventive batch)
 **9 sites batch fix:**
 - `PurchaseEvaluationFeatures.cs` 4 sites: Create + Default detail + UpdateDraft + AdjustBudget
 - `PurchaseEvaluationDetailFeatures.cs` 5 sites: Detail Insert/Update/Delete + Quote Insert/Update/Delete + Select Winner (1 inside if-block 16-space indent)
 **Pattern:**
 ```csharp
 UserName = currentUser.FullName ?? currentUser.Email
 ```
 ICurrentUser interface đã có FullName + Email từ JWT claims — KHÔNG inject userManager mới.
 `Edit replace_all=true` 1 pass cover 8 sites cùng indent + 1 site manual fix indent.
 111/111 PASS local. Run #220 PASS, bundle UNCHANGED (BE-only commit).
 ### Plan AF — Bug 6 historical entries pre-Plan AE missing name
 Bro: "phiếu cũ ko thể hiện đc người edit nhỉ ?"
 Plan AE chỉ forward — entries pre-deploy có `userName=""` empty.
 #### Plan AF commit `506cada` (em main solo, Option A bro chốt)
 FE ApprovalsTab + HistoryTab build `userMap useMemo` từ embedded PeDetailBundle data:
 ```tsx
 const userMap = useMemo(() => {
  const m = new Map<string, string>()
  if (ev.drafterUserId && ev.drafterName) m.set(ev.drafterUserId, ev.drafterName)
  ev.approvals.forEach(a => {
    if (a.approverUserId && a.approverName) m.set(a.approverUserId, a.approverName)
  })
  ev.approvalFlow?.steps?.forEach(s =>
    s.levels?.forEach(l =>
      l.approvers?.forEach(ap => {
        if (ap.userId && ap.fullName) m.set(ap.userId, ap.fullName)
      })
    )
  )
  ev.levelOpinions?.forEach(o => {
    if (o.signedByUserId && o.signedByFullName) m.set(o.signedByUserId, o.signedByFullName)
  })
  ev.departmentOpinions?.forEach(o => {
    if (o.userId && o.userName) m.set(o.userId, o.userName)
  })
  return m
 }, [ev])
 const resolveUserName = (l: PeChangelog): string => {
  if (l.userName && l.userName.trim() !== '') return l.userName
  if (l.userId) {
    const name = userMap.get(l.userId)
    if (name) return name
  }
  return 'Hệ thống'
 }
 ```
 NO extra API fetch (`/api/users` admin permission). Cover gần hết users tham gia phiếu. Mirror × 2 app §3.9.
 Run #221 PASS, bundle rotate × 2 app (admin `DR95zKWg → C8TvDy7r`, user `BAj_Yaj5 → BvcWrq2z`).

 ## 📋 Patterns reusable saved S25 (8 NEW)
 1. **Multi-Changelog.Add() SQLite frozen-clock tie-break (gotcha #48)** — Test query audit table cần filter EntityType/Summary discriminator thay raw OrderByDescending(CreatedAt). Cross-ref Contract V2 test setup tương lai.
 2. **CICD Monitor catch UAT skip test risk validated** — Cho BE refactor > 100 LOC + signature change, UAT mode `feedback_uat_skip_verify` skip `dotnet test` RISK. Em main resumed local test verify post Plan AB Chunk A2 fix.
 3. **Test fix Option A over BE refactor preservation** — Khi test fail post-refactor do test logic assumption broken, ưu tiên tests get more specific selector (filter discriminator) thay vì revert BE code change. Code semantic stays clean, tests adapt to new schema reality.
 4. **Capture pre-call mutation state cho audit row from-position** — Khi Service mutate entity state AND write audit row simultaneously (vd Plan AC ApplyReturnModeAsync mutate pointer + log Approval), snapshot OLD Step/Level BEFORE mutation. Pattern reusable Contract V2 audit + Budget V2 audit.
 5. **FE merge synthetic rows từ Changelog historical (Plan AC2 Option 2A)** — Reversible recovery KHÔNG DB write. ApprovalsTab fetch changelogs + reconstruct synthetic rows từ existing audit data + dedupe timestamp bucket key vs real rows. Reusable Contract V2 + Budget V2 audit visualization without DB migration.
 6. **Drop misleading dual-phase badges + parse semantic next-target hint (Plan AD, gotcha #49)** — UI audit history KHÔNG nên render dual-phase badge khi state machine self-loop (ChoDuyet → ChoDuyet là advance pointer trong cùng phase). Thay bằng Decision badge + semantic hint parse từ structured comment via regex + keyword detect.
 7. **Changelog UserName preventive systemic batch fix (Plan AE)** — Khi audit phát hiện 1 site bug pattern, grep enumerate ALL similar sites. `Edit replace_all=true` với context-aware key (UserId + Summary) cover N sites idempotent. ICurrentUser.FullName fallback Email mirror LogTransitionAsync pattern.
 8. **FE userMap fallback từ embedded domain data (Plan AF Option A)** — Build composite lookup map từ data có sẵn trong response bundle (drafter + approvals + approvalFlow + levelOpinions + departmentOpinions), KHÔNG cần extra API fetch admin permission. Trust entry.userName non-empty → userMap.get(entry.userId) → 'Hệ thống' fallback.

 ### 48. Multi-Changelog.Add() trong cùng SaveChangesAsync → SQLite frozen-clock tie-break → tests `OrderByDescending(CreatedAt).First()` non-deterministic (Session 25 Plan AB + Run #215 catch)
 **Triệu chứng:** Plan AB Chunk A `cdfd542` add SECOND Changelog.Add() entry vào `ApplyReturnModeAsync` (cover Bug 2 — Return mode log) end-of-function. Caller `TransitionAsync:100` đã có sẵn `LogTransitionAsync` add FIRST Changelog entry (Action=Transition + ContextNote=comment chứa "không lùi được"). 2 entries cùng `SaveChangesAsync` transaction → SQLite test fixture frozen clock → CreatedAt **identical microseconds** cho cả 2 rows.
 Plan M edge case tests (S23 t3) query `.OrderByDescending(c => c.CreatedAt).FirstAsync()` assert `ContextNote.Contains("không lùi được")` — sau Plan AB, SQLite tie-break non-deterministic, pick Plan AB row (EntityType=Workflow, Action=Update, ContextNote=null) → `Expected ContextNote not to be <null>` FAIL.
 **CI Run #215 sha=cdfd542** test_infra FAIL 2/53 (51 PASS, 2 FAIL):
 - `ApplyReturnMode_OneStep_AtStep1_ResetsToBuoc1Cap1_KeepsChoDuyet` (line 350)
 - `ApplyReturnMode_OneLevel_AtStep1Level1_ResetsToBuoc1Cap1_KeepsChoDuyet` (line 308)
 Test gate caught regression → deploy never reached → prod spared broken state.
 **Fix Option A (chốt):** Test query filter by `Summary.Contains("Chuyển phase")` để pick đúng LogTransition entry. Plan AB BE code stays clean.
 ```csharp
 // Trước Plan AB Chunk A2:
 var changelog = await db.PurchaseEvaluationChangelogs
    .Where(c => c.PurchaseEvaluationId == pe.Id)
    .OrderByDescending(c => c.CreatedAt)
    .FirstAsync();
 // Sau Plan AB Chunk A2 fix (commit 8c05947):
 var changelog = await db.PurchaseEvaluationChangelogs
    .Where(c => c.PurchaseEvaluationId == pe.Id && c.Summary!.Contains("Chuyển phase"))
    .OrderByDescending(c => c.CreatedAt)
    .FirstAsync();
 ```
 **Pattern reusable:** Khi handler/service add NEW Changelog row trong existing flow đã có LogTransition row, tests query audit table MUST filter EntityType / Action / Summary keyword **discriminator** thay vì raw OrderByDescending timestamp. Cross-ref Contract V2 test setup tương lai.
 **Severity:** Major — caught by CI before prod ship, no user impact. Lesson reinforced UAT mode `feedback_uat_skip_verify` skip `dotnet test` per chunk RISK khi BE refactor > 100 LOC + signature change → em main resumed local test verify post Plan AB Chunk A2.

 ### 49. UI dual-phase badge `fromPhase → toPhase` gây nhầm khi 3/4 Reject mode giữ Phase=ChoDuyet (Session 25 Plan AD)
 **Triệu chứng:** Bro UAT 2026-05-19 Plan AC deploy: panel "Lịch sử duyệt" 6 entries TẤT CẢ hiện `Đã gửi duyệt → Đã gửi duyệt` (vì 3 mode Return OneLevel/OneStep/Assignee giữ Phase=ChoDuyet sau Mig 28 — chỉ Drafter mode set TraLai). Reject entry visually IDENTICAL Approve entry → user nhầm "Đã trả lại nhưng vẫn hiện đã duyệt".
 **Fix Plan AD (commit `0aaf2df`):**
 1. **Drop fromPhase → toPhase badges entirely** trong ApprovalsTab (cả `fe-user` + `fe-admin` mirror §3.9). Visual confusion gỡ bỏ.
 2. **Thay bằng next-target hint parse từ comment** via helper `extractNextTargetHint(decision, toPhase, comment)`:
   - **Approve:** Summary "sang Cấp X" → "→ Cấp X", "sang Bước Y" → "→ Bước Y (Cấp 1)", "Duyệt vượt cấp" → "→ Vượt cấp tới Cấp cuối", toPhase=DaDuyet(20) → "→ Đã duyệt hoàn tất"
   - **Reject:** ContextNote "Người chỉ định" → "→ Trả về Người chỉ định (Bước X Cấp Y)" parse regex, "Người soạn thảo"/"Drafter" → "→ Trả về Người soạn thảo", "không lùi được" → "→ Không lùi được", "Trả về 1 Cấp"/"Trả về Cấp X" → "→ Lùi về Cấp X", toPhase=TuChoi(99) → "→ Từ chối hoàn toàn"
 3. **Decision badge** (Plan AC `a734bf2` đã add): Duyệt emerald / Trả lại amber / Từ chối rose — phân biệt Action level KHÔNG dựa vào phase.
 **Pattern reusable cross-project:** UI audit history KHÔNG nên render dual-phase badge khi state machine self-loop (e.g. ChoDuyet → ChoDuyet là advance pointer trong cùng phase, KHÔNG phải transition). Thay bằng Decision badge + semantic next-target hint parse từ structured comment.
 **Severity:** UX confusion (KHÔNG functional bug). Bro UAT phản hồi sau Plan AC deploy.
