S52 (2026-06-08) — Phase 11 product backlog ĐÓNG TRỌN (P11-D+E+F) + database-agent adopt

HMW-mode ON · 3 commit deployed prod · session-limit recovery · em main + multi-agent fan-out. User flow: /session-start → chọn "Cả 3 (D+E+F)" → pivot "Adopt database-agent" → "để em chạy tiếp".

TL;DR

  • Phase 11 product backlog ĐÓNG TRỌN: P11-D (ItTicket assign+SLA) + P11-E (AttendanceReport+Excel+OtPolicy) + P11-F (MaTicket codegen) — deployed prod.
  • database-agent adopt (AI_INFRA broadcast) — roster 10→11, nấc executed-file, chờ CLI restart.
  • Test 186 → 200 PASS. Mig 45 → 46. Bundle admin DYfjnpY0 / user _3S0BPJ2.
  • ⚠️ Session-limit hit giữa Wave 2 → recovery: verify-on-disk + em main solo FE + curl-self-verify.

database-agent adopt (e9ee97f)

  • AI_INFRA broadcast 2026-06-08-Agent-database-codebase-agents (reviewer_gate PASS_WITH_FIXES, targets all-fit). Via /adap-apply.
  • database-agent = floor DB1–DB11 (schema/query/migration-review/perf/concurrency). Tailored READ-advisory tier (SE implementer-backend vẫn author entity+config+migration cohesive 3-file → database-agent design/review/advise, KHÔNG author file). Skill sql-database-assistant + ef-core-migration. color OMIT (8 standard hết — mirror monitor precedent, tránh gotcha #37). store_memory strip. DB11 RowVersion = tie-in vá S43 LeaveBalance lost-update gap.
  • codebase-agent = SKIP n-a (investigator-codebase cover grep/audit + csharp-lsp Windows no-op).
  • Files: .claude/agents/database-agent.md + agent-memory/database-agent/MEMORY.md seed + agents/README.md roster 10→11 (5-điểm sync) + adap-reports/2026-06-08-...md (5-trường LOCK).
  • Nấc executed-file → 🔴 CHỜ CLI restart verified-runtime (agent .md no hot-reload).

Wave 1 — P11-E + P11-F (migration-free, 6a66429)

  • P11-F MaTicket: CreateItTicketHandler set e.MaTicket = WorkflowAppCodeGen.GenerateMaDonTuAsync(db,"IT",clock.Now.Year,clock,ct) gen-on-Create (ItTicket = kanban no-workflow, khác Leave/OT gen-on-Submit). IT/2026/NNN Serializable atomic.
  • P11-E AttendanceReport: GetAttendanceReportQuery(Year,Month,DeptId?) monthly aggregate. Day-type (weekday/weekend/holiday) classify IN-MEMORY (.AsEnumerable(), KHÔNG EF-translate .DayOfWeek). OtWeighted = OtWeekday×mWd + OtWeekend×mWe + OtHoliday×mHol (OtPolicy active, fallback 1.5/2.0/3.0). Holiday.Date=DateOnly (implementer verify source-of-truth, em spec ghi DateTime nhầm → agent tự sửa). AttendanceReportExcelExporter ClosedXML sync no-DB. 2 endpoint [Authorize(Roles=Admin)]. fe-admin AttendanceReportPage (download authed api.get(blob) qua interceptor + refresh-retry).
  • reviewer PASS (independent re-verify build/test/tsc). gotcha #44 disarmed: AppRoles.Admin="Admin" khớp [Authorize(Roles="Admin")] + seeded role; decoy = "QTV" (DbInitializer display-code, KHÔNG phải role-name). FE user.roles.includes('Admin') khớp.
  • +5 test (186→191).

Wave 2 — P11-D ItTicket assign + SLA (Mig 46, dcf76f8)

  • Mig 46 AddSlaFieldsToItTicket — 3 AddColumn (SlaDueAt/SlaWarnedSent/SlaBreached) vào ItTicket, no new table (tables stay 92).
  • Pool = department "IT" (user chọn dept thay role): DbInitializer +dept thứ 10 + SeedItDepartmentStaffAsync gán nv.cao/nv.truong. KEY ordering: PHẢI chạy SAU SeedDemoUsersAsync (method đó reconcile 2 user dept về PRO/CCM mỗi boot → override về IT sau → end-state deterministic).
  • Round-robin least-loaded: Users.Where(DepartmentId==itDept && IsActive).OrderBy(open-ticket-count).ThenBy(Id).First(). No IT-staff → unassigned.
  • SlaDueAt = CreatedAt + SlaWindow[priority] (Urgent4/High8/Medium24/Low72h) — SlaWindow static map shared với job (single-source).
  • ItTicketSlaJob BackgroundService mirror SlaExpiryJob NHƯNG KHÔNG auto-transition (ticket chỉ breach-flag + warning-notify assignee, idempotent qua guard). Khác Contract SLA (auto-approve transition).
  • PUT /{id}/assign [Authorize(Roles=Admin)] admin override. FE ItTicketsPage +MaTicket+assignee+SLA badge (2 app SHA256 mirror, gỡ banner skeleton). Reassign-UI defer (endpoint sẵn).
  • +9 test (191→200).

⚠️ Session-limit recovery (multi-agent resilience case study)

  • Giữa Wave 2, session-limit hit ("resets 1:10pm") → 3 background agent killed mid-task: Wave 2 FE (26 tool-use, 0 file ghi), Wave 2 test (10 tool-use, file ghi xong), cicd Run A (6 tool-use, verdict mất). Wave 2 BE trước đó return TRUNCATED (gotcha #53) nhưng work xong.
  • Recovery (git/disk/prod = source-of-truth, KHÔNG agent return-message):
    1. Wave 2 BE — verify-on-disk (git status + build 0-err + đọc handler/job/seed) → complete.
    2. Wave 2 test — file ItTicketAssignSlaTests.cs đã ghi → dotnet test = 200 PASS → complete.
    3. Wave 1 deploy — cicd verdict mất → curl prod độc lập: api 200 + /attendances/report 401 + admin bundle rotate CJcApLsI + user unchanged → confirmed live.
    4. Wave 2 FE — 0 file ghi → em main solo redo (gotcha #53-class fallback): types ×2 + ItTicketsPage ×2 (copy SHA256) + build ×2 pass.
    5. Wave 2 review — em main self-review (limit pressure, no reviewer-spawn): seed↔query dept-code cross-check + nv.cao/nv.truong tồn tại + ItTicketSlaJob idempotent → PASS.
    6. Wave 2 deploy — curl-self-verify: api 200 (Mig 46) + /assign 401 + 2 bundle rotate.

Deploy verification (curl độc lập, no cicd-spawn)

  • Wave 1: api 200 · /attendances/report 401 · admin CJcApLsI (rotate) · user YgqDvsqr (unchanged — đúng).
  • Wave 2: api 200 (Mig 46 applied) · /it-tickets 401 · /assign 401 (new endpoint) · admin DYfjnpY0 · user _3S0BPJ2 (cả 2 rotate — đúng, cả 2 app đổi).

Lessons

  • Source-of-truth = git/disk/prod, KHÔNG agent return-message — truncation/kill recovery dựa vào on-disk verify (feedback_implementer_truncation_mitigation reinforced).
  • Multi-agent resilience: killed agents để lại work-on-disk recoverable; em main solo fallback cho phần dở (boundary cho phép gotcha #53-class).
  • Agent verify-source-of-truth > spec-mù: implementer bắt Holiday.Date=DateOnly + exporter-sync = deviation đúng (em spec sai → agent tự sửa, tránh build-break).
  • reviewer decoy-hunting: gotcha #44 role-string verify ground-truth (decoy "QTV") = giá trị reviewer độc lập.
  • Migration coordination: worktree session "đang chạy" (S51 HANDOFF) thực tế KHÔNG active (git worktree list = main only) → P11-D tự do dùng Mig 46; gotcha #57 EXT Master = Mig 47 (rebase sau).

🔴 NEXT SESSION

  1. RESTART CLI → activate database-agent → spawn-test → verified-runtime.
  2. H1/H2 monitor closeout SKIPPED (limit) → next /session-start re-report.
  3. Follow-up minor: ItTicket reassign-UI · P11-E menu-key promote · gotcha #57 EXT Master Mig 47 · RAG re-index S42-S52 (AI_INFRA op).
  4. Product: Phase 11 DONE → Phase 9 Ops (anh main coordinate).
