[CLAUDE] Docs: Session 24 chốt cuối - Plan AA cumulative 7 commits + 4 agent MEMORY drift wrap

S24 wrap deliverables:

Docs:
- docs/STATUS.md prepend Recently Done newest S24 chốt cuối row (cumulative 7 commits 3 core + 4 polish UAT iteration, multi-agent ROI ~175K ~28% solo equiv)
- docs/HANDOFF.md Last updated S24 chốt cuối (replace previous S24 t1 entry với cumulative final state)
- docs/changelog/sessions/2026-05-15-s24-turn1-plan-aa-workflow-matrix.md EXTEND
  - Phase 2 Polish iteration UAT feedback section (4 commit detail):
    - Polish 1 da218f1 hotfix container px-2
    - Polish 2 4d60598 redesign v1 panel-per-NV color mirror Designer
    - Polish 3 fbbd361 redesign v2 HTML table rowSpan tận dụng full width
    - Polish 4 ee0902a wrap fix sidebar label về đầu hàng (hanging-indent reverse)
  - Stats S24 chốt cuối table
  - Multi-agent ROI cumulative S24 table (6 owner)
  - 7 Patterns reusable cross-project saved
  - Pending S25+ checklist

4 agent MEMORY drift (3 agent flushed cumulative S24 wrap + 1 CICD prior Run #210):
- .claude/agent-memory/investigator/MEMORY.md S24 Pre-A entry + memory drift note
- .claude/agent-memory/implementer/MEMORY.md +3 patterns 13/14/15 (Designer mirror + Tailwind JIT palette + rowSpan flat row builder) + S24 polish REFUSE log
- .claude/agent-memory/reviewer/MEMORY.md +4 anti-patterns (polish iteration cost vs spawn ROI + Discovery #3 negative retest + Low note IsUserSelectable leak)
- .claude/agent-memory/cicd-monitor/MEMORY.md Run #210 PASS entry (Plan AA verify 4/4 wire end-to-end)

⚠️ Implementer + CICD Monitor agent MEMORY both over 25KB curate threshold (~31.5KB + ~43KB).
Recommend archive S20-S22 old entries next session via `archive/2026-05-S20-S22.md`.

User-level memory: NO update needed per §6.2 (responsive memory đã đúng 2-panel,
hanging-indent + JIT palette patterns captured trong agent Implementer MEMORY).

Test verify post-Plan AA: 111/111 PASS unchanged (58 Domain + 53 Infra). No regression.

Phase 2 polish 4 commit liên tục UAT feedback bro: `da218f1` hotfix px-6→px-2 (content sát sidebar) + `4d60598` redesign v1 panel-per-NV mirror admin Designer color coding (drop table symbol khó hiểu) + `fbbd361` redesign v2 HTML table rowSpan tận dụng full width (Bước/Cấp/NV/Quyền duyệt grid 2-col 7 label tiếng Việt nguyên văn) + `ee0902a` wrap fix sidebar label dài về đầu hàng (hanging-indent reverse CSS: flex→block + inline-block icon + inline text + absolute ChevronDown + text-[12px] leading-snug × 5 sites mirror 2 app). Patterns reusable saved: (1) Tailwind JIT palette array (5-color cycle Step + Cấp), (2) HTML table rowSpan flat row builder helper, (3) hanging-indent reverse CSS pattern. Multi-agent ROI: ~175K total (Investigator 32K Pre-A + Implementer 14K Chunk B + Reviewer 25K cumulative + CICD 12K Run #210 + 3 agent flush ~12K + em main ~80K) ≈ 28% solo equiv. **CICD Run #210 PASS 4/4 wire end-to-end**: IsUserSelectable filter live (admin no-filter / admin ghim / nv.test ghim all HTTP 200) + menu Pe_DuyetNcc_WfView present + Order shift idempotent 1-10 contiguous + non-admin permission Read OK + bundle hash rotate 2 app + Mig 31 unchanged.

Q&A clarify 2 lượt: Q1 Permission strategy "Relax class-level [Authorize]" (đã fix gotcha #44 permanent từ S18 → CHỈ cần add filter param), Q2 Matrix layout "Table 2D full 7 Allow* cột".

Pattern reinforced: (1) gotcha #44 relax pattern PROVEN cross-stack reuse — Workflows endpoint từ admin-only sang any-auth read accessible. (2) DbInitializer INSERT-only → INSERT-OR-UPDATE-Order safe shift existing prod rows (idempotent re-deploy). (3) Plan U truncate revert pattern: widen sidebar + drop truncate, keep `min-w-0 flex-1` + `shrink-0` + `title` tooltip (no harm). **Surprise:** PE Workspace là **2-panel** không phải 3-panel — memory `feedback_responsive_laptop_breakpoint.md` stale claim → defer update memory. **3 commits push pending** (`ee776d5..<this>`).

 | 2026-05-12 | Claude | **🎯 SESSION 21 turn 1 — Add con thứ 4 cicd-monitor (Path A — post-deploy verifier green READ tier, 1 commit `f1c61c9`)** — User chốt Path A sau pre-flight Plan G Trial Week 1: thêm sub-agent thứ 4 chuyên post-deploy verify (Gitea Actions poll + bundle hash 2 app verify + sqlcmd mig prod = repo latest + endpoint smoke). Trade-off: +~150K spawn extra mỗi run, đổi lại catch deploy ship fail tự động — recurring blind spot pattern em main solo S20 quên verify ~30% push. **2 file mới**: `.claude/agents/cicd-monitor.md` (~7KB) — system prompt + 8-step workflow (verify push → poll Gitea API → fail log grep → live curl smoke → bundle hash × 2 app + verify changed → sqlcmd mig prod = repo latest → report PASS/FAIL/PARTIAL/TIMEOUT/SKIPPED-DOCS) + 5-stage report table + gotcha #25/#39/#40/#41/#44 cross-ref + skill `iis-deploy-runbook`/`dependency-audit-erp`/`ef-core-migration` preload + Anti-pattern 9 rules. `.claude/agent-memory/cicd-monitor/MEMORY.md` (~5KB seed) — recurring CI bug patterns + 5-stage checklist + baseline build/bundle metrics + bearer test pattern admin/nv.test. **1 file update repo**: `.claude/agents/README.md` — 4-agent architecture diagram (green slot mới) + decision tree (after push code + prod issue diagnose branches) + memory routine 4 SendMessage + skills preload 4 agents + cost reality table 564K → 750K spawn / 1.2M → 1.35M heavy / 600K → 700K optimized + trial workflow Week 1-3 CI/CD Monitor spawn integrated + pass criteria + catch ≥1 deploy ship fail. **Memory user-level update**: `feedback_multi_agent_setup.md` — title 3 → 4 sub-agents, decision tree +CI/CD Monitor invocation branches (after push + user prod issue), skills preload list +CI/CD Monitor (iis-deploy-runbook + dependency-audit-erp + ef-core-migration), cost table update + trade-off rationale (recurring blind spot ~30% push S20). **CI skipped**: all 3 file changed `.md` → match `paths-ignore: '**/*.md'` per gotcha #41 → no Gitea Actions run → no IIS deploy (expected — agent infra là local Claude Code, không cần present trên prod). Push success `36e21c8..f1c61c9 main -> main`. **3 (now 4) sub-agents vẫn seeds-only**: chưa spawn work nào — em main solo via context paste + Write file. KHÔNG flush 3 agent MEMORY.md (chưa spawn work = không findings, per §6.5 KHÔNG add noise entry). cicd-monitor MEMORY.md có entry "setup 2026-05-12" trong seed.
