decimal(18,2) + GhiChu nvarchar(1000) + audit (BaseEntity).
### ContractChangelog (1) — Domain/Contracts/
Unified audit log. Khác ContractApprovals (workflow-only, dùng cho guard
logic) — Changelog là VIEW LAYER cho user đọc lịch sử thao tác:
- EntityType enum: Contract | Detail | Workflow | Comment | Attachment
- Action enum: Insert | Update | Delete | Transition
- PhaseAtChange snapshot
- UserId + UserName denormalize (log readable)
- Summary human-readable + FieldChangesJson [{Field, Old, New}]
- ContextNote (comment kèm theo)
## EF Configurations
ContractDetailsConfiguration.cs (1 file gộp 7 IEntityTypeConfiguration):
- ToTable + HasMaxLength + HasPrecision per type
- HasOne(Contract).WithMany(<TypeDetails>) cascade delete
- IX (ContractId, Order) cho load timeline
ContractChangelogConfiguration.cs:
- Cascade delete khi Contract xóa
- IX (ContractId, CreatedAt) timeline + IX (ContractId, EntityType) filter
## DbContext + IApplicationDbContext
+ 8 DbSet mới (7 Details + ContractChangelogs).
## Migration 9: AddContractDetailsAndChangelog
3-file rule (gotcha #17): .cs + .Designer.cs + ApplicationDbContextModel
Snapshot.cs đầy đủ. Applied LocalDB SolutionErp_Dev OK — 24 + 8 = 32 bảng
total.
