### Correctness (Static — Structural Evidence)

| Requirement                        | Status        | Notes                                                                                  |
|------------------------------------|---------------|----------------------------------------------------------------------------------------|
| Embedded storage default           | ✅ Implemented | `clients/cerebro/src/config.rs` default `StorageMode::EmbeddedSurreal`.                
| No silent fallback on init failure | ✅ Implemented | `clients/cerebro/src/storage/mod.rs` returns error when `StorageFallback::None`.       
| Migration CLI subcommands          | ✅ Implemented | `clients/cerebro/src/bin/cerebro.rs` includes `migrate import` and `migrate validate`. 
| File-based legacy export import    | ✅ Implemented | `clients/cerebro/src/migration/legacy.rs` reads JSON export file.                      
| Validation uses counts + checksums | ✅ Implemented | `clients/cerebro/src/migration/mod.rs` uses `canonical_json_checksum`.                 
| Migration report schema            | ✅ Implemented | `clients/cerebro/src/migration/report.rs` matches design schema.

### Coherence (Design)

| Decision                                   | Followed? | Notes                                                                          |
|--------------------------------------------|-----------|--------------------------------------------------------------------------------|
| Default storage mode is embedded SurrealDB | ✅ Yes     | Default set in `clients/cerebro/src/config.rs`.                                
| No silent fallback on storage init         | ✅ Yes     | `StorageFallback::None` returns error in `clients/cerebro/src/storage/mod.rs`. 
| Migration tooling via CLI subcommands      | ✅ Yes     | `clients/cerebro/src/bin/cerebro.rs` uses clap subcommands.                    
| File-based legacy export format            | ✅ Yes     | `clients/cerebro/src/migration/legacy.rs` reads file export.                   
| Validation uses counts + checksums         | ✅ Yes     | `clients/cerebro/src/migration/mod.rs` uses checksum per collection.
