[CLAUDE] PurchaseEvaluation: freeze ngân sách phiếu DaDuyet — Mig 67 snapshot 11 cột + display-gate budgetFrozen + 2 terminal-guard (UAT anh Kiệt 07-16)

- Bug UAT: PeWorkItemBudgets (record NS dùng chung per Dự án × Hạng mục) sửa được sau duyệt → phiếu ĐÃ DUYỆT đổi số retroactive (detail-bundle load pair LIVE :911 + FE fallback ?? bs.*).
- Fix: Mig 67 AddPeApprovedBudgetSnapshot — 11 cột ApprovedBudget* trên PurchaseEvaluations; helper ApplyBudgetSnapshotOnFinalizeAsync gọi ở 5 site set DaDuyet (4 finalize + admin-override catch-all — reviewer catch #81-class, assignment qua biến lọt literal-grep); display-gate: DaDuyet+SnapshotAt → serve snapshot + BudgetFrozen=true + CanEdit=false, else LIVE (R2: NS live vẫn là "bản cập nhật gần nhất" cho phiếu chưa duyệt — UpdatePeBudgetPro/Ccm giữ nguyên không phase-guard).
- 2 terminal-guard block CẢ Admin: SetPeCcmBudgetPeriod + AdjustBudget → Conflict khi DaDuyet/TuChoi (đường chính thống: un-terminal → duyệt lại → re-snapshot overwrite).
- Backfill idempotent phiếu DaDuyet cũ = live hiện tại (số tại-thời-điểm-duyệt không khôi phục được — Changelogs attribution-gap); OUTER APPLY dịch đúng predicate PeBudgetAccumulator (3 bản khớp: SQL ↔ accumulator ↔ code gốc); demo-seeder DbInitializer cũng snapshot (fresh-DB gap — reviewer catch).
- PeBudgetAccumulator extract lũy kế behavior-preserving (dùng chung GetDetail live + helper snapshot); FE 2 app: types +budgetFrozen + PeDetailTabs badge khoá NS (SHA-mirror giữ, hash 2 app bằng nhau).
- Tests 509→520 (T0 reproduce RED→GREEN + T1-T9 + AdminOverride site-5); build slnx 0/0; npm build ×2 PASS; Mig applied 2 LocalDB (Dev catch-up cả Mig 66 lag).
- Pipeline S133: /fable-real invest (wf_348f6155) → spec → HMW Opus MAX (wf_d9639faa / wf_4bef08b8 / wf_75c6bfd3) → reviewer PASS_WITH_FIXES (wf_f9c0b939) → 2 SHOULD fixed. #53 return-fail ×3/5 lane — disk-truth recover 3/3, 0 mất việc.
