Ghi TỪNG MỤC trong lúc làm (chống #53). Không sửa file production. Không commit. Nguồn đo: file migration + Designer + ModelSnapshot + 7 EF Configuration + sqlcmd LocalDB Dev/Design.

3. Đối chứng sqlcmd LocalDB (DB1/DB10 — schema THẬT, không trí nhớ)

sqlcmd -S "(localdb)\MSSQLLocalDB" -d SolutionErp_Dev -E :

TABLECOUNT|96
CSPTABLE|ContractSigningPlanApprovals
CSPTABLE|ContractSigningPlanAttachments
CSPTABLE|ContractSigningPlanChangelogs
CSPTABLE|ContractSigningPlanDossierItems
CSPTABLE|ContractSigningPlanLevelOpinions
CSPTABLE|ContractSigningPlanLines
CSPTABLE|ContractSigningPlans
MIGTOP|20260729122015_AddContractSigningPlans
MIGCOUNT|69

-d SolutionErp_Design :

DESIGN_TABLECOUNT|96 · DESIGN_CSP|7 · DESIGN_MIGTOP|20260729122015_AddContractSigningPlans · DESIGN_IXCOUNT|27

→ 2 DB parity TUYỆT ĐỐI (96/96 bảng · 7/7 CSP · cùng mig-top · 27 index = 20 IX + 7 PK). → KHÔNG có committed-but-unapplied-local drift (khác bẫy S53). → Acceptance §③-B "sys.tables 89 → 96" = ĐẠT (đo được 96; delta +7 khớp 7 CreateTable).

Index thật trong DB (27 dòng, khớp 1:1 file mig)

Nhóm filtered (soi gotcha #57):

ContractSigningPlanLines | IX_..._ContractSigningPlanId_SupplierId | unique=1 | ([IsDeleted]=(0)) | ContractSigningPlanId,SupplierId
ContractSigningPlans     | IX_ContractSigningPlans_MaKeHoach        | unique=1 | ([MaKeHoach] IS NOT NULL) | MaKeHoach

Các IX còn lại filter = - (không filter), unique=0 trừ IX_ContractSigningPlanLevelOpinions_ContractSigningPlanId_ApprovalWorkflowLevelId (unique=1, không filter — bàn ở §2e/§4).

FK thật (8 FK, cột `delete_referential_action_desc`)

Approvals    → ContractSigningPlans  CASCADE
Attachments  → ContractSigningPlans  CASCADE
Changelogs   → ContractSigningPlans  CASCADE
DossierItems → ContractSigningPlans  CASCADE
LevelOpinions→ ContractSigningPlans  CASCADE
Lines        → ContractSigningPlans  CASCADE
LevelOpinions→ ApprovalWorkflowLevels NO_ACTION   (= Restrict)
ContractSigningPlans → ApprovalWorkflows NO_ACTION (= Restrict)

→ 6 con Cascade 1-hop + 2 Restrict, đúng y spec §②-2/4. Zero FK vật lý sang PE/Project/Supplier/User/Contract (loose-Guid, convention Mig 49) — xác nhận bằng chính danh sách 8 FK trên (không có dòng nào trỏ PurchaseEvaluations/Suppliers/Projects).
