[CLAUDE] Docs: Chunk G — K8 Plan K wrap S23 t1: docs + session log + Designer comment cleanup + 3 agent MEMORY drift

Plan K Mig 31 F2 refactor sang per-Approver-slot DONE — 8 commits cumulative
S23 t1 (`56868bf..<this>`). K8 wrap docs + dirty MEMORY.md commit:

Docs updates:
- docs/STATUS.md: Last updated S23 t1 entry với Plan K summary 8 chunk
- docs/HANDOFF.md: TL;DR S23 t1 đầy đủ (top) — multi-agent ROI evidence
- docs/database/schema-diagram.md §14: title Mig 22-31 (was 22-29) + add
  Mig 30 F4 + Mig 31 F2 blocks per slot Approver + DROP Users column note
- NEW docs/changelog/sessions/2026-05-14-s23-turn1-plan-k-mig31-f2-refactor.md
  session log đầy đủ 8 chunk timeline + multi-agent spawn cost table + pattern
  reinforced 3×

FE Admin Designer comment cleanup (Reviewer K2 follow-up):
- ApprovalWorkflowsV2Page.tsx lines 73-75 + 502-504: 2 stale narratives "F2
  AllowDrafterSkipToFinal xuống per User (User Management)" rewrite Mig 29+30+31
  cumulative narrative "7 Allow* ALL xuống per Level slot, pattern proven 3×"

3 agent MEMORY.md drift commit (dirty từ session start S23 + S22 chốt):
- Investigator: K0 pre-flight findings + 5 surprises catch
- Reviewer: K2 PASS report + new pattern "transient sentinel zombie" anti-pattern
- CICD Monitor: S22 chốt verify cumulative (Run #193 + S23 t1 pending K9 spawn)

User-level memory updates (cross-project diary persisted ngoài repo):
- feedback_per_nv_permission_scope.md: reinforcement S23 t1 — Pattern 3×
  cumulative (Mig 29 + Mig 30 + Mig 31). Pattern ALSO applies cho refactor existing
  scope, KHÔNG chỉ greenfield. Cross-ref discoveries Plan K (compile-break workaround,
  stale narrative drift, transient sentinel zombie anti-pattern caught Reviewer).
- MEMORY.md index: cumulative reinforcement note 3× Mig 31

Verify:
- dotnet build production projects clean
- npm run build fe-admin pass 17.76s, 0 TS err
- Test 104/104 PASS (S23 t1 K7 chunk maintained baseline)

Plan K state final: 31 mig · 59 tables · ~145 endpoints · 104 test · 47 gotcha
· 20 memory · 6 skills · 4 sub-agents active. CHƯA push remote — chờ bro confirm
K9 spawn CICD Monitor.

+- **2026-05-14 (S23 t1 spawn K0 — Plan K F2 refactor pre-flight):** Audit F2 state cho Plan K Mig 31 (move `Users.AllowDrafterSkipToFinal` → `ApprovalWorkflowLevels.AllowApproverSkipToFinal` + change semantic Drafter Nháp → Approver ChoDuyet skip thẳng Cấp cuối). **Confirmed state Mig 30:** Migrations path = `Persistence/Migrations/` (not direct `Migrations`); 30 mig latest = `20260513160703_AddAllowApproverEditBudgetToLevels`; `User.cs:38` AllowDrafterSkipToFinal prop; `ApprovalWorkflow.cs:86-105` 6 Allow* props (4 ReturnMode + EditDetails + EditBudget) per Level slot; F2 Drafter branch ở `PurchaseEvaluationWorkflowService.cs:119-161` trong SUBMIT branch (line 125 `if (skipToFinal && evaluation.ApprovalWorkflowId is Guid skipAwId)` check user.AllowDrafterSkipToFinal); APPROVE STEP branch ở `~line 393-525` (advance pointer). TransitionAsync signature: `skipToFinal` là param thứ 8 (position 47:47), default=false. `TransitionPurchaseEvaluationCommand` ở `PurchaseEvaluationFeatures.cs:393-402` với param `SkipToFinal=false` default. `ApprovalWorkflowOptionsDto` ở `PurchaseEvaluationDtos.cs:86-92` (6 field). `PurchaseEvaluationDetailBundleDto.DrafterAllowSkipToFinal` ở line 217 + `CurrentLevelOptions` ở line 214. UsersController `PATCH /users/{id}/allow-skip-final` ở line 91-98 + `SetAllowDrafterSkipToFinalBody` ở line 105. `SetUserAllowDrafterSkipToFinalCommand` ở `UserFeatures.cs:332`. **FE state:** fe-admin Designer `system/ApprovalWorkflowsV2Page.tsx` slot label "NV #{ei + 1}" ở line 873 (KHÔNG phải "#NV {order}" theo prompt) — inline checkbox panel 5+1=6 checkbox ở line 853-933 (4 ReturnMode + EditDetails + EditBudget). fe-admin `system/UsersPage.tsx` "Skip cuối" column line 306-318 + FastForward button toggle line 365-372 + allowSkipMut hook line 181-186. fe-admin/fe-user PeDetailTabs Drafter Workspace checkbox "Gửi thẳng Cấp cuối (skip trung gian)" ở line 287-297 (admin) / 294-304 (user). **GAP fe-user**: KHÔNG có UsersPage + ApprovalWorkflowsV2Page (admin-only mgmt) → Plan K UI changes localized fe-admin chỉ; fe-user side chỉ touch PeDetailTabs (remove old Drafter checkbox + thêm Approver toggle near Duyệt button). **Drift Dev DB**: Total=2 user (admin + test.drafter), Flagged=0 — NOT match 33-user prod seed. **Prod actual**: Total=33 / Flagged=4 (NOT 2 per S22+2 spec). 4 user flagged sẽ lose value when DROP column — acceptable per new semantic (Drafter pre-submit moot).
 - **2026-05-13 (S22, no spawn — em main solo throughout):** S22 18:00→~21:00 em main solo. Cumulative state: 30 mig (+1 Mig 30 `AddAllowApproverEditBudgetToLevels` F4 per-Level slot), 104 test PASS (+20: 5 reg #44 Authorize policy + 7 ReturnMode + 7 Guard + 1 V2 actor scope reject), ~146 endpoints (+3: PATCH /users/{id}/allow-skip-final + PATCH /pe/{id}/budget-adjust + GET /pe/{id}/attachments/{attId}/view), 46 gotcha unchanged, 19 memory unchanged (recommend +1 entry — see below). Prod active users 13→33 (+20 role-based: act.nv/pp/tp, bod.1/2, equ/fin/hra/pm/qs.nv/pp/tp). **Discoveries S22:** (1) **Per-NV admin opt-in flag pattern reinforced 2×** — Mig 30 F4 cùng pattern Mig 29 F1+F3 (S21 t5). Bro corrected em main lần đầu: "phải tick checkbox như Section 2", default = admin opt-in per slot, KHÔNG = mở rộng default. Cross-ref memory `feedback_per_nv_permission_scope.md` proven 2×. (2) **Plan F drop V1 ABORTED** — pre-flight sqlcmd reveal Contract entity HOÀN TOÀN V1 chưa wire V2 (chưa có ApprovalWorkflowId column) + 4 PE V1-only + 19 PE V1+V2 mix. Lesson: drop migration cần verify entity scope toàn bộ (Contract liên đới — không chỉ PE). (3) **Identity password policy ≥12 chars** — seed 20 user FAIL 400 với "User@123456" (11 chars), `TestUser@2026` (13 chars) pass. (4) **Identity rename atomic 4 fields** confirm gotcha #38: Email + NormalizedEmail + UserName + NormalizedUserName + FullName; sqlcmd cần `SET QUOTED_IDENTIFIER ON` cho filtered unique index. (5) **API login response field name `accessToken` + `refreshToken` + `user`** — KHÔNG có field `token` (correct prior Bash example trong spec dùng `.token` sẽ fail). (6) **PS 5.1 ASCII-only script discipline** reinforced gotcha #30: `seed-test-users-prod.ps1` viết Vietnamese names without diacritics tránh parser error. Recommend bro add 1 memory entry "Admin opt-in flag pattern proven 2×" cumulative Mig 29 + Mig 30.
 - **2026-05-13 (S21 t3-t5, no spawn):** Em main solo 3 turns (bug fix gotcha #45 + F1+F2+F3 workflow-level Mig 28 + refactor per-NV Mig 29). Implementer REFUSE per cross-stack reasoning chain rule. Investigator KHÔNG spawn — em main đã có context cumulative S20 t12 setup + active dev throughout. No findings to flush. Cumulative state update: 84 test, 29 mig, 45 gotcha, 19 memory entries (+2 S21 t5 pending), 6 skills unchanged. Pattern reusable saved cho future spawn: per-NV permission scope split + EF migration ADD→BACKFILL→DROP reorder.
 - **2026-05-11 (setup):** Investigator agent initialized. Baseline knowledge load complete (44 gotchas + 14 memory entries + 6 skills + 27 mig + 81 test pass cumulative). No investigations performed yet. Awaiting first SendMessage from em main.
