[CLAUDE] Docs: Session 26 chốt cuối — 6 Plan AG series PE tree view + Plan AI RAG global MCP setup

Update:
- docs/STATUS.md: Last updated S26 cumulative wrap
- docs/HANDOFF.md: TL;DR S26 chốt cuối với 3 pattern reusable NEW
- docs/changelog/sessions/2026-05-21-s26-pe-tree-view-rag-setup.md: NEW session log đầy đủ
- docs/guides/multi-agent-setup-guide.md: NEW ~750 lines onboarding 4 dự án future
- .claude/agent-memory/*/MEMORY.md: 4 agent flush S26 entries
- .claude/rag.json: NEW project config cho RAG bootstrap

Plans done S26:
- Plan AG/AG2/AG3/AG4/AG5/AG6 — 6 commits 0bf6c7e..d99069a PE List tree view UI iteration
- Plan AI Phase 0-4 — RAG global MCP setup (Voyage-4-large + Qdrant Windows native binary v1.18.0 NO Docker + FastMCP 3.3.1 stdio + SQLite FTS5 BM25 + RRF k=60 + Anthropic Contextual Retrieval prepend)
- SOLUTION_ERP bootstrap: 126 files → 2,392 chunks indexed 60.9s (~484K Voyage tokens = 0.24% free tier 200M/month)

Multi-agent ROI S26: 5 spawn (Inv 2 audit 5Q + RAG distribution research 4 study cases + Imp 1 Case 2 + Rev 1 pre-commit + CICD 1 Run #222) ~123K + em main solo Plan AG2-AG6 polish + Plan AI Phase 0-4 ~280K = ~28% solo equivalent.

3 patterns reusable cross-project NEW S26:
1. Pattern 19 Implementer — HTML native <details>/<summary> + Tailwind named groups (group/proj+year+sup) + localStorage Set<string> cho hierarchical 3-level tree UI when no Accordion lib
2. RAG User-level Global MCP — 1 server localhost serve N project + per-project .claude/rag.json (Approach A — 1 dev solo scenario, không phải team VPS)
3. Qdrant Windows native binary deployment — no Docker overhead, qdrant-x86_64-pc-windows-msvc.zip 28.3MB chính thức GitHub release

Pending S27+:
- Memory CURATE 4 agent (cicd-monitor 74KB OVER 50KB hard threshold URGENT)
- Plan AI Phase 5 bootstrap 4 project còn lại (NamGroup/DH Y Dược/Ashico/Vipix)
- Plan AI Phase 6 file watcher + Windows Task Scheduler

+- **2026-05-21 (S26 Run #222 PASS Plan AG + 5 subsequent runs em main solo verify):** Run #222 sha=`0bf6c7e` Plan AG Phase 1 PE List tree view 2-level — Stage 4d bundle hash 2/2 ROTATED ✓ (admin `C8TvDy7r → CWHIdoFo`, user `BvcWrq2z → Bg2FNeIz`), Stage 4a admin token 468 + nv.test token 477, Stage 4b smoke 5/5 endpoints 200, Stage 4c PE List API shape preserved (all 9 fields present: maPhieu/tenGoiThau/type/phase/projectId/projectName/selectedSupplierName/contractId/createdAt). Test gate 111 unchanged. Mig 31 prod unchanged. Token ~12k. **Subsequent Plan AG2-AG6 (5 commits `c5429c0..d99069a`) em main solo verify** — CICD KHÔNG spawn per UAT iteration mode `feedback_uat_skip_verify` + cost ~150K spawn × 5 = ~750K wasteful for trivial UI polish. Em main verify mỗi push: git push success + Gitea auto-trigger build → wait ~3-4min deploy → bundle hash visual check (KHÔNG full smoke). Plan AG4 BE+FE cross-stack (DTO + 3 projection JOIN Users+Departments + FE PE card render): dotnet test 111/111 PASS local verify trước push. **Pattern saved: CICD Monitor spawn 1 lần đầu tiên Phase wire (Plan AG initial) — verify bundle rotate baseline + endpoint shape. Subsequent polish chunks (CSS/UX/copy)** trong cùng Plan: em main self-verify bundle visual + smoke 1 endpoint, KHÔNG re-spawn. ROI tốt cho 1 dev solo iteration scenario. **Cumulative S26 6 runs** #222 (AG) + #223 (AG2) + #224 (AG3) + #225 (AG4) + #226 (AG5) + #227 (AG6) verified PASS by em main bundle check + visual confirm bro UAT. 0 prod regression. **Memory size BEFORE update ~72KB, AFTER ~74KB — CRITICAL CURATE next session priority MAX URGENT** (archive Run #186-#221 verbose entries to `archive/2026-05-runs.md` + keep Run #222-#227 + summary cumulative).

 - **2026-05-19 13:05-13:08 — Run #221 id=335 sha=`506cada` VERDICT=PASS (S25 t7 Plan AF — FE userMap fallback resolve historical entries pre-Plan AE).** Push range cumulative S25 remote = `e23f51c..506cada` (7 commits Plan AB+AC+AC2+AD+AE+AF since S24). Tip commit Plan AF: 2 FE-only files mirror `fe-user/src/components/pe/PeDetailTabs.tsx` (+74 LOC, ApprovalsTab+HistoryTab userMap useMemo + resolveActorName/resolveUserName helpers) + `fe-admin/src/components/pe/PeDetailTabs.tsx` (+70 LOC mirror §3.9 identical logic). Duration ~3m23s (~baseline). Pre-push em main local: npm build × fe-user PASS 0 TS err (9.12s), npm build × fe-admin PASS 0 TS err (8.91s), BE unchanged from 9ea62be. Status poll 5 iter (13:06→13:08) status `running → success`. **CRITICAL Stage 4c Plan AF wire VERIFY ✓:** Endpoint `GET /api/purchase-evaluations/3248f2f9-c6e9-43ff-a4ca-067ffecf9f36` returns PeDetailBundle with ALL 5 userMap data sources present: `drafterUserId=ce7eb96a` + `drafterName="Nguyễn Văn Duy"` ✓, `approvals` (6 entries) ✓, `levelOpinions` (5 entries) ✓, `departmentOpinions` (0 entries — field present, no rows OK) ✓, `approvalFlow.steps` (3 steps with nested levels.approvers) ✓. FE userMap useMemo will build composite lookup từ embedded domain data, NO extra API contract change. Stage 4a Auth admin: HTTP 200 token len 468 ✓ (password `Admin@123456`, accessToken field). Stage 4b Smoke 5/5 endpoints 200 ✓ (`/api/purchase-evaluations`, `/api/contracts`, `/api/menus`, `/api/users`, `/api/purchase-evaluations/{id}`). **Stage 4d Bundle hash 2/2 ROTATED ✓ as expected (FE touch):** admin `DR95zKWg → C8TvDy7r` ✓, user `BAj_Yaj5 → BvcWrq2z` ✓. Stage 4e Health ready 200 + Health live 200 ✓. Mig prod TOP 1 = `20260514160124_RefactorSkipToFinalToApproverLevel` (Mig 31) unchanged ✓ (Plan AF no schema change). **Discovery 1 — 503 mid-deploy expected:** During IIS publish step API returned 503 Service Unavailable ~13:08:07 (app pool recycle window ~5-15s before deploy stage complete), self-recovered post-deploy 200. Discovery 2 — Auth route NOT `/api/v1/auth/login` (404) but `/api/auth/login` (CLAUDE.md route). Token field NOT `token` but `accessToken`. **Pattern saved Plan AF — FE userMap fallback synthetic recovery for audit trail:** When historical entries with empty `userName` field exist pre-data-fix deploy (Plan AE forward-only fix BE side), apply **FE-only fallback lookup builder pattern** using embedded domain bundle data sources (drafter + approvals + workflow approvers + opinions). Build composite Map<userId, fullName> via useMemo at top of Tab component, expose resolveXxxName(entry) helper: 1) trust entry.userName if non-empty, 2) lookup userMap by entry.userId, 3) fallback "Hệ thống". Reusable cho Contract changelog audit + Budget changelog audit historical recovery without extra API contract change (avoid /api/users admin-only permission constraint for non-admin viewers). Mirror 2 FE app §3.9 identical logic. Token cost ~10k. **Memory size BEFORE update ~69KB, AFTER ~72KB — DEDICATED CURATION SESSION REQUIRED NEXT (archive Run #186-#210 + S22-S24 verbose entries to `archive/2026-05.md` priority MAX REINFORCED).**
 
 - **2026-05-19 12:33-12:36 — Run #220 id=334 sha=`9ea62be` VERDICT=PASS (S25 t6 Plan AE — Changelog UserName 9 sites populate via ICurrentUser.FullName fallback Email).** Push range cumulative S25 remote = `e23f51c..9ea62be` (6 commits Plan AB+AC+AC2+AD+AE since S24). Tip commit Plan AE: 2 BE-only files `PurchaseEvaluationFeatures.cs` (+6 LOC, 4 sites: Create×2/UpdateDraft/AdjustBudget) + `PurchaseEvaluationDetailFeatures.cs` (+7 LOC, 5 sites: 1 inside if-block 16-space indent) — uniform pattern `UserName = currentUser.FullName ?? currentUser.Email`. Duration ~3m25s (~baseline). Pre-push em main local: `dotnet test SolutionErp.slnx` PASS 111/111 (~5s). Status poll 4 iter (12:33→12:36) status `running → success`. **CRITICAL Stage 4c Plan AE wire VERIFY ✓:** Endpoint `/api/purchase-evaluations/3248f2f9-c6e9-43ff-a4ca-067ffecf9f36/changelogs` returns 20 entries len 6822 bytes. 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). Post-Plan AE deploy: new Budget Adjust action will populate userName correctly (FullName fallback Email). Bro test verification: trigger 1 Budget Adjust on any PE → next entry will show userName ✓. 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/.../changelogs`). **Stage 4d Bundle hash 2/2 UNCHANGED ✓ as expected (BE-only commit):** admin `DR95zKWg` (= Run #219 baseline), user `BAj_Yaj5` (= Run #219 baseline). Stage 4e Health ready 200 "Healthy" + Health live 200 ✓. Mig prod TOP 1 = `20260514160124_RefactorSkipToFinalToApproverLevel` (Mig 31) unchanged ✓ (Plan AE no schema change). **Pattern saved Plan AE — Changelog audit log UserName populate batch:** When detecting systemic gap "Changelog field X not set in N similar Add() sites" (Bug ngày 19/5 bro report Budget Adjust empty user column), do **preventive batch fix across ALL Changelog.Add() sites in same domain** (PE = 9 sites: 4 Features + 5 DetailFeatures), KHÔNG chỉ fix 1 site phát hiện. Pattern reusable for Contract changelog + Budget changelog future (similar entity types with audit trail). Source pattern `UserName = currentUser.FullName ?? currentUser.Email` — assumes ICurrentUser is injected scoped DI (already standard). Side benefit: 8 preventive sites future-proof against same bug pattern. Token cost ~14k. **Memory size BEFORE update ~66KB, AFTER ~69KB — STRONG CURATE REQUIRED next session (defer dedicated curate priority MAX).**
