[CLAUDE] Docs: S98 harness backlog — Fable-restore gỡ caveat H5.6 (runtime-verified spawn-test ×2) + monthly→2026-08-01 + skill Mig 60/61 + re-tier mega-line S93/S94→archive-S98 + cicd L1 curate + 3 orphan-append H2 + ledger mode-A note + email AI_INFRA

Verify: V1 conservation PASS (arithmetic full-accounting 0-byte-unaccounted) · V2 cross-doc PASS (detector 28→25, còn lại false-positive class) · V3 moved-not-cut PASS (sha-match + byte-arithmetic đóng vòng).

 - **S52 (2026-06-08):** Seeded (em main, adap-apply database-agent). Roster 10→11. Nấc executed-file. CHỜ restart + spawn-test → verified-runtime.
 - **S56 (2026-06-09) — pre-golive verify (2nd real spawn, verified-runtime ✓):** Schema/Mig integrity P11 + S55 master-data = SOLID. Mig 42-48 applied IDENTICALLY Dev+Design+prod `.\SQLEXPRESS` (48 mig / 92 tables, **NO S53-style unapplied-local drift**); 0 pending model-snapshot diff; **9 gotcha-#57 filtered-unique** confirmed BOTH EF config (HasFilter×13) AND DB (`filter_definition=([IsDeleted]=(0))`) incl Vehicle/Driver day-1; FK đúng (LeaveBalance→LeaveType Restrict + UNIQUE(User,Type,Year); 4× LevelOpinions Cascade(parent)/Restrict(Level)+UNIQUE composite; ItTicket SLA nullable). **DB11 FAIL (1 major, fast-follow KHÔNG blocker):** `LeaveBalance.UsedDays += NumDays` @ `LeaveOtApprovalFeatures.cs:361-386` chạy bare SaveChanges (no tx / no RowVersion / READ COMMITTED) → concurrent double-approve lost-update. **S43 gap STILL OPEN.** Fix-pattern sẵn repo: Serializable tx (codegen `:34`) HOẶC RowVersion+retry (1 mig). Low-prob ~30 user, recoverable Admin Adjustment. Tag [s56, pre-golive-verify, schema-pass, db11-lostupdate-open].
 - **S57bis (2026-06-11) — PE gắn Hạng mục design (3rd real spawn, DELIVERED — on-behalf em main ghi hộ, H2-proposed):** Introspect LocalDB → design `PurchaseEvaluations.WorkItemId Guid?` scalar **loose-Guid + IX, KHÔNG FK vật lý** — nhất quán convention PE (ProjectId/SelectedSupplierId đều loose; duy nhất ApprovalWorkflowId có FK). Guard = validator + handler mirror S43 FK-invariant. KHÔNG đụng CodeSequences (mã phiếu giữ `PE/{YYYY}/{A|B}/{Seq}`). LEARNED: PE FK-convention map (loose-Guid là norm module này — FK vật lý là exception). SURPRISE: WorkItems = catalog GLOBAL (KHÔNG ProjectId) → 2 dropdown độc lập; "Dự án (năm) – Hạng mục" chỉ là chuỗi ghép hiển thị, không ràng buộc quan hệ. Ship: Mig 49 deploy Run #381 prod-applied. Tag `[s57bis, mig49-design, on-behalf]`.

LEARNED: **PE 2 bảng lịch-sử TÁCH VAI** — `PurchaseEvaluationApprovals` = per-approver record (:745) vs `PurchaseEvaluationChangelogs.ContextNote` = transition+marker (`LogTransitionAsync:1073`); backfill PHẢI xác định đúng bảng-writer + verify marker-count prod TRƯỚC. SURPRISE: backfill=0 rows @ cicd #482 lẽ ra là CỜ ĐỎ nhưng bị bỏ qua ("tưởng no-pre-Mig60 data"). Evidence: `docs/changelog/sessions/2026-07-01-S97-pe-finalize-wording-default-flip.md:97-133`.
