[CLAUDE] Docs: S51 session-end closeout — error-ledger §L + monitor spawn-records + root counts

§L.a/b: E-002 RESOLVED (gotcha #57 LeaveType/Shift/OtPolicy filtered Mig 45) + NEW E-007/AS-11 (parallel-fan-out FE<->BE contract mismatch, reviewer-caught pre-commit) + Active-Guards (#57 guard 2->3 verified + reviewer cross-stack guard). H2 GATE PASS 5/5 + H1 CHOT 4-mat spawn-records appended (both wrote 0 files - E-006 backstop held). CLAUDE.md root counts 43->45 mig / 91->92 tables / 181->186 test. HANDOFF: database-agent /adap-apply recommend next-session + doc-drift backlog coords. CI-skip (docs/.md only).

 - **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).
