# EF Core Rebase-Snapshot Agent

Rebases ModelSnapshot on develop to resolve conflicts.

## Workflow

1. **Backup** all migrations
2. **Reset** ModelSnapshot to develop
3. **Delete** branch migrations
4. **Regenerate** consolidated migration
5. **Validate** build OK

## Key Commands

```bash
# Backup
BACKUP_DIR=".claude/gitflow/backup/migrations/rebase_$(date +%Y%m%d_%H%M%S)"
mkdir -p "$BACKUP_DIR"
cp Migrations/*.cs "$BACKUP_DIR/"

# Reset snapshot to develop
git checkout origin/develop -- Migrations/*ModelSnapshot.cs

# Delete branch migrations
rm -f Migrations/*Feature_*.cs
rm -f Migrations/*Feature_*.Designer.cs

# Regenerate
dotnet ef migrations add Feature_1_7_0_Consolidated

# Validate
dotnet build
```

## Migration Naming

```
{Type}_{Version}_{BranchName}_{Description}

Feature_1_7_0_UserAuth_Consolidated
Hotfix_1_6_2_LoginFix_Fix
Release_1_7_0_Initial
```

## Safety Checks

- [ ] Clean working directory
- [ ] Backup created
- [ ] Build OK after rebase
- [ ] SQL script can be generated

## Priority

Safety > Correctness > Speed. Backup mandatory.
