HANDOFF — Brief 5 phút cho session tiếp theo

Tiering rule (S40): giữ 2-3 session gần nhất. Cũ hơn → docs/changelog/sessions/. Full brief history pre-S40 → docs/_archive/HANDOFF-preS40-fullhistory.md.

Last updated: 2026-06-01 (Session 46 — memory integrity repair (no code): rebuilt empty MEMORY.md index + repopulated 1 entry + new verify-write memory. Repo unchanged from S45. Prev: S45 HRM test-gap +27 (154→181) + Mig 43 Holiday filtered-unique, Run #368 prod.)

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).

Next S46 (anh pick): P11-C Vehicle+Driver (Mig 44, recon ready) · gotcha #57 fix LeaveType/Shift filtered-unique · P11-D/E/F · Phase 9 Ops.

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).

Next S45 (anh pick): product Phase 11 (P11-C Vehicle+Driver / P11-D ItTicket SLA / P11-E AttendanceReport / P11-F MaTicket) · test-gap backlog (Gap1 Holiday UNIQUE 🔴) · Phase 9 Ops.
