S51 (2026-06-08) — P11-C Vehicle+Driver catalogs + gotcha #57 ext (HMW-mode ON · product feature · deployed prod)

User: /session-start → "P11-C Vehicle+Driver" → "làm đi / chạy luôn cho nhanh". HMW fan-out, ship to prod.

Done (commit 30a99aa → Gitea Run #371 PASS ~4m18s, verified prod):

• Mig 44 AddVehicleAndDriverCatalogs — extend HrmConfigs +2 declarative kind (Vehicle/Driver), 2 catalog table filtered-unique day-1. BE Region 5/6 CRUD + Controller +2 route (GET public/write Admin) + MenuKeys +All (auto perm) + DbInitializer idempotent seed. FE KIND_CONFIG +2 ×2 app SHA256 mirror + 4-place (:kind-driven, no new route). Tables 91→92 (sys.tables ground-truth — narrative "93" was +1 drift).
• Mig 45 FilterHrmCatalogUniqueIndexesByIsDeleted (bundled gotcha #57) — LeaveType+ShiftPattern+OtPolicy filtered (3 HRM catalog; OtPolicy missed in "2 catalog" backlog, caught via grep). +5 test-before (181→186 RED→GREEN).
• reviewer caught 1 MAJOR → fixed: Driver FE↔BE required-field mismatch (root = inconsistent em-main brief BE-required vs FE-optional).
• cicd Run #371: bundle admin Cg9mvltU/user YgqDvsqr, 5 idx filtered ([IsDeleted]=(0)) live, smoke 200, /hrm-configs/{vehicles,drivers} wired.

🔴 NEXT SESSION:

• gotcha #57 EXT (worktree session đang chạy): Department/Supplier/Project (Master) → Mig 46 (3 idx, confirmed-reachable). Merge khi xong — nó tạo Mig 46; main KHÔNG tạo migration nào nữa → no conflict, chỉ cần sequence đúng.
• RAG/Qdrant DOWN: restart rag-infra.ps1 -Action ensure (AI_INFRA repo) → verify list_projects. RAG re-index S42-S51 stale (AI_INFRA op).
• AI_INFRA-side carry-over: /check-email se pull S50 handshake.
• Product (anh pick): P11-D ItTicket SLA / P11-E AttendanceReport+OtPolicy multiplier / P11-F MaTicket / Phase 9 Ops.
• Doc backlog (low): STATUS/HANDOFF over-tiering (re-tier) · schema-diagram §16+ Mig 27-45 gap · agent baselines stale (reviewer 130-test/investigator counts → monthly 2026-07-01).

S50 (2026-06-07) — S49 Harness 1·2·3 verified-runtime closeout (HMW-mode ON · infra-finish, no product, CI-skip)

User: /session-start → chọn "Finish S49 infra" → /session-end. Đóng trọn 3 phần S49 milestone (verified-runtime).

Done (em main + 4 sub spawn — all background per visibility feedback):

• (a) /session-start spawned 2 monitor sub (tooling-auditor H1 + harvest-curator H2) → verified-runtime CONFIRMED. H1 caught + em main patched 3 freshness drifts (plugin 15→18, skill-index 31→43 mig / 49→57 gotcha, verified-runtime markers). H2 harvest 🟢 clean (0-byte/orphan=0). Test 181 PASS, RAG 2415.
• (b) H2 wave-mode VERIFIED — Workflow hmw.js wave-run h2-verify (Run wf_b7e4d6ef-787, 2-agent: investigator-codebase read-only + test-specialist write-direct). B6 isolation HELD (git status 6-baseline, sub-MD gitignored, chunk 2415=2415, B4 both-paths). Bonus: gotcha #57 exact coords.
• (c) H3 email send-path VERIFIED — /send-email ai_infra handshake (body-hash c9656c19… self-verified MATCH) → broadcasts/outbox/ai_infra/ + _index.md OUTBOUND.
• session-end §L: H2 GATE PASS 5/5 + B5 wave-gom (2 sub-MD → agent-memory). H1 freshness CHỐT (0 new-alloc). §L.a scan: no new RCA (E-005 git-add guard held — staged specific files).

🔴 NEXT SESSION:

• AI_INFRA-side (their step): /check-email se → pull SE handshake → confirm 2-way byte-identical; optional reply /send-email se so SE tests receive-path (ai_infra/outbox/se/ currently empty).
• Product (anh pick): P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 (coords ready: LeaveTypeConfiguration.cs:19 + ShiftPatternConfiguration.cs:19, template HrmConfigHolidayTests.cs:180-197, test-before) · P11-D/E/F · Phase 9 Ops.
• Cleanup (optional): wave-folder .claude/workflows/wave-h2-verify/ harvested → safe to delete (gitignored transient).
• Doc backlog (low): STATUS Recently Done + HANDOFF over tiering (re-tier next consolidation) · agents/README.md:13 ASCII 7→10 lanes (cosmetic).

S49 (2026-06-07) — AI_INFRA Harness 1·2·3 adopt (HMW-mode ON · governance/infra, no product code)

User: /ultra-on + /adap-apply harness 1·2·3 — BẬT HMW-mode rồi adopt 3 broadcast harness của AI_INFRA.

HMW flow: marker .claude/hmw-mode.on tạo (ON) → P2 recon fan-out 4 read-only agent (3× investigator-codebase gap H1/H2/H3 + 1× investigator-api plugin audit · return-delta · 367K tok ~4m46s) → P3 harvest → em main single-writer WRITE ~25 file → reviewer P4 PASS all 3. Containment post-P2: git-diff 1 file-write (inv-api self-MEMORY benign) + chunk-count 2414=2414 (0 RAG-write) = defense-in-depth proven.

Done:

• H1 (Self-observability): roster 8→10 — NEW 2 sub TÁCH BIỆT (anh-mandate H1≠H2 "hay quên+nhầm") tooling-auditor (tooling/docs-freshness 4-mặt) + harvest-curator (harvest-integrity 5-trục), INFORM-only (4 RAG-read, NO store_memory/Write) + 2 memory seed. Wire session-start.md Phase 2.1.1 RE-REPORT + session-end.md §L.b 6→7-step. H3 plugin/skill = gộp-vai doc (0 agent mới).
• H2 (wave-folder isolation): hmw.js wave-mode (subMdPath + tool-aware writeGuard) + .gitignore wave-*/+agent-teams/ (B6 git-check-ignore VERIFIED) + NEW .claude/workflows/README.md. ADD-mode (chỉ workflow DÀI). A agent-team n-a (Windows in-process).
• H3 (email channel): NEW broadcasts/ (outbox/{6 others+all} + inbox/{6 others} + _index + inbox/README + 13 .gitkeep, committed) + 2 cmd send/check-email (self=se, 6 others short-id {ai_infra,vipix,dyd,namgroup,ashico,bvaau}) + adap-apply base-path fix outbox/all/.
• 3 adap-report docs/governance/adap-reports/2026-06-07-Agent-harness-{1,2,3}.md + reviewer PASS (no blocker; 1 MINOR pre-existing README diagram → fixed). Test 181 unchanged (no .cs).

🔴 S49 NEXT-FIRST — status S50: restart done. (a) ✅ DONE S50 — /session-start spawned 2 monitor sub, both loaded + ran RE-REPORT clean → verified-runtime CONFIRMED (H1 found 3 freshness drifts → patched; H2 harvest 🟢 clean, 0-byte/orphan none); (b) ✅ DONE S50 — wave-run h2-verify (Run wf_b7e4d6ef-787, 2-agent): B6 isolation HELD (git status 6-baseline, sub-MDs gitignored, chunk 2415 unchanged), B4 both-paths exercised (write-direct + read-only-scribe); B5 harvest → harvest-curator @session-end; (c) ✅ SE-side DONE S50 — /send-email ai_infra handshake written + body-hash self-verified (c9656c19…); AI_INFRA /check-email se pull = their step to complete 2-way byte-identical proof.

Next product (anh pick): P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 LeaveType/Shift filtered-unique · P11-D/E/F · Phase 9 Ops.

S48 (2026-06-02) — adap-* verification closure post-restart + FD2 proof + Gov-v2 error-ledger

User: "làm xong hết đi rồi session-end luôn" — đóng cả 3 adap item post-restart, rồi session-end.

Restart confirmed done (registry có frontend-designer agent + adap-* commands + 8 subs KHÔNG store_memory) → S47 verified-pending nâng cấp. /adap-apply all-pending = 0 mới (cả 3 applied S47). /adap-report all-applied re-assess + update 3 report (honest §C5/G-015).

Done (em main solo + 1 FD spawn):

• #1 store_memory strip → VERIFIED-runtime — grep agents tools:=0 · registry 0/8 subs. (Caveat giữ: KHÔNG "read-only" — sub vẫn có Bash/Write; containment = defense-in-depth.)
• #2 frontend-designer FD2 → VERIFIED-RAN — 🩷 first real spawn (background). Full FD2 loop trên fe-user /login: read DS → Vite dev → Playwright shot 375+1440 → viewed PNG → FD4 rubric all-PASS → contrast fix LoginPage.tsx:56 slate-500→600 → re-shot → build PASS. em main mirror fe-admin (parity). Rig lessons (FD MEMORY): (1) Vite-dev networkidle never fires → domcontentloaded+selector; (2) cold-start dep-optimize >15s → warm-up goto 60s. Fact: SE = Tailwind v4 CSS-first (@theme{} in index.css, NO tailwind.config.js).
• #3 Gov-v2 delta → CLOSED (executed-file) — NEW docs/governance/error-ledger.md (blameless RCA E-001..E-004 + Active-Guards 2-strike index + §L.a AS-1..AS-9 deterministic-detect + 3-ledger triad map) + §L.b 6-step wired session-end.md Phase 1.5 (ran live this session = demo).

Code shipped: fe-{admin,user}/src/pages/LoginPage.tsx subtitle contrast a11y (slate-500→600, ~7.5:1). Build ×2 PASS 0 TS error. Test 181 unchanged (FE-only, no .cs). → code commit deploys → 🟩 cicd-monitor verify bundle rotate.

⚠️ NEXT SESSION: (a) ✅ DONE — cicd Run #369 PASS, login fix live (admin DPPTx2Kw/user CjoUEsoV, Mig 43, health 200); no action; (b) §L.b chạy AUTO từ /session-end kế (session này chạy thủ công — command no hot-reload); (c) wire reviewer làm FD4 design-gate (quality-ADD, defer); (d) RAG re-index S42-S48 (AI_INFRA op).

Next product (anh pick): P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 LeaveType+Shift filtered-unique (test-before) · P11-D/E/F · Phase 9 Ops.

S47 (2026-06-02) — AI_INFRA adap-* adoption channel + 3 broadcasts (infra/governance, no product code)

Installed federated adoption channel (AI_INFRA relay): 3 slash-commands .claude/commands/adap-{apply,report,request}.md (forked verbatim). Read AI_INFRA broadcasts/outbox/ read-only (§J2) → apply own repo → docs/governance/adap-reports/<id>.md. 3 reports written. 0 agents spawned (em main solo).

Adopted 3 broadcasts (all nấc executed-file / verified-pending — restart needed, agent/cmd .md no hot-reload):

• #1 store_memory strip — removed from ALL 8 subs → lead (em main) = sole RAG-writer (em main keeps it). 4 RAG-read retained. Corroborates SE S41 re-bootstrap-loss lesson.
• #2 frontend-designer (8th agent, pink) — adopted (user call), forked canonical FD1–FD10 visual-verify floor, tailored SE stack + use-existing-DS + boundary ⟂ implementer-frontend.
• #3 Gov-v2 — already-applied S44, delta report (gap: no formal error-ledger/§L.b checklist).

🔴 NEXT SESSION FIRST (anh restart CLI): 1 restart activates 3 commands + store_memory strip + frontend-designer. Then spawn-test frontend-designer small design task → confirm FD2 Playwright loop runs THẬT (upgrades #2 verified-pending → verified). Optional /adap-report all-applied re-confirm.

Follow-ups (non-blocking): (a) broadcast #3 formal error-ledger/§L.b checklist; (b) wire reviewer as FD4 design-gate; (c) RAG re-index S42-S47 (AI_INFRA op).

Next product (anh pick): P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 LeaveType/Shift filtered-unique · P11-D/E/F · Phase 9 Ops.

S46 (2026-06-01) — Memory integrity repair (no code, docs-only)

/session-start audit phát hiện S45 close-out để lại 2 file user-memory 0 byte — MEMORY.md (index) + feedback_background_spawn_visibility.md. Index rỗng = S46 bootstrap chạy KHÔNG có memory auto-inject (degrade thầm lặng).

Done (👤 em main solo, no agent spawn):

• Rebuilt MEMORY.md index — 14 entry (8 feedback + 3 project + 2 pattern). Repopulate feedback_background_spawn_visibility từ HANDOFF/STATUS S45 ref (marked reconstructed). NEW feedback_session_end_memory_write_verify.
• Verified 0 empty .md (find -size 0 = 0). STATUS count drift "27"→14 corrected. Test gate re-confirm 181 PASS lúc bootstrap.
• Memory files NGOÀI repo (~/.claude/.../memory/) → no git commit cho memory. Chỉ repo docs (STATUS+HANDOFF) = docs-only commit, CI skip.

Root cause: S45 session-end flush tạo stub rồi Write body truncate (gotcha #53 — S45 có test-specialist truncate). File 0-byte không báo lỗi + ngoài git-track → trôi tới S46 mới lộ.

Next S47 (anh pick): P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 fix LeaveType/Shift filtered-unique · P11-D/E/F · Phase 9 Ops · (optional) add verify-byte-count step vào /session-end skill — đề xuất AI_INFRA per charter v2.

S45 (2026-06-01) — HRM test-gap stabilization + Holiday drift fix (Mig 43)

2 commit 051b62b (Tests +27) + 0c5a014 (Mig 43) → push → cicd Run #368 PASS, verified prod. 154→181 test.

Done:

• Đóng 3 test-gap deferred S35-S38 (stabilize before extend): Gap1 Holiday composite UNIQUE (7) + Gap2 EmployeeSatellite FK-invariant/soft-delete/cascade (10) + Gap3 gotcha #44 authz regression HrmConfigs+Employees (10). 🟪 test-specialist viết (return truncated #53 → 👤 em main verify-on-disk + proxy MEMORY).
• Mig 43 FilterHolidayUniqueIndexByIsDeleted (👤 em main solo) — Gap1 test lòi bug thật: Holiday DB UNIQUE (Year,Date) unfiltered vs handler !IsDeleted → admin xoá + thêm lại ngày lễ cùng date = 500 reachable. Fix .HasFilter("[IsDeleted]=0") (khớp pattern 13×). 🟩 cicd verify filtered index live prod. Table vẫn 91 (index-only), FE bundle unchanged (đúng — BE-only).
• 🟦 P11-C recon sẵn: Vehicle+Driver = extend HrmConfigs +2 kind declarative (Mig 44), giữ VehicleBooking free-text.

gotcha #57 NEW: soft-delete + UNIQUE → MUST .HasFilter("[IsDeleted]=0"). ⚠️ LeaveType.Code + ShiftPattern.Code vẫn unfiltered (cùng bug, backlog test-before). Process: feedback_background_spawn_visibility (foreground spawn im lặng "looks frozen" → đẩy background + report ngay).

S44 (2026-06-01) — Monthly drift audit + AI_INFRA bundle 06-01 (docs-only, 2-way VERIFIED)

4 commit ae30f8f → 5b8736d → 071c25c → 5dbcad3, pushed, tree clean. CI-skip (all .md). 154 test unchanged (no code).

Done:

• Monthly cadence audit (cron 2026-06-01, next 2026-07-01): 🟦 investigator-codebase ground-truth-from-disk scan → 👤 patch 42 count-drift fixes (40→42 mig · 84/59/55/47→91 tables · 130/111→154 test · 52/49→56 gotcha) across CLAUDE.md + docs/CLAUDE.md + ef-core/dependency-audit skills + schema-diagram + database-guide. schema-diagram migration table +Mig 17-42; ef-core history +Mig 27-42; detailed-§ ERD gap (Mig 27-42 modules) flag EXPLICIT → deferred backlog.
• AI_INFRA bundle 06-01 adopt (full scope): §A RAG T1/T2 auto · §C 7/7 agent-mem L1 ≤16KB + "25KB"→"~30KB tiered" ×7 · §D #4 self-report step → /session-end Phase 6.3 (skip #1 have/#3 helper) · §E/§F report+ledger docs/governance. AI_INFRA RT3 re-verified độc lập → VERIFIED 2-way, ĐÓNG HẲN.
• Carry-over S40 ĐÓNG (5b8736d): BROADCAST-2 infra-feedback committed (governance trail) + .mcp.json gitignored (machine-path local, no secret).

Lesson: "incremented-per-session" counts drift → re-ground từ code monthly (count files). gotchas.md header KHÔNG có self-count → mỗi cite = downstream copy (patch từng chỗ). → memory feedback_monthly_drift_audit.

Còn lại (AI_INFRA-owned, non-blocking): eval baseline cite 11,922 cũ + SE full re-index (last-index 05-29, S42-S44 stopgap) → AI_INFRA op, batch chung web-MCP migration (ping nếu cần cross_project_search SE tươi sớm).
