- Checklist used: [QC-DCD-001]

- Mode: autonomous, not independent (reviewer is `AI as stand-in for S01`)

## Checklist Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | SOLID principles applied; no god classes with excessive responsibilities | Pass | Each class has one responsibility (Class Table); view, view model, session, deck and adapters are separate. |
| 2 | Visibility markers correct and consistent (`+` public, `-` private, `#` protected) | Pass | Visibility markers are on all members. |
| 3 | Relationships correctly distinguished: Association vs Aggregation vs Composition vs Dependency | Pass | Composition (Vocabulary and Card), aggregation (Deck), association, dependency and realization are distinguished. |
| 4 | Multiplicities and navigability specified on all associations | Pass | Multiplicities are on the associations; dependencies are directed. |
| 5 | Applied design patterns are annotated explicitly (e.g. Singleton, Factory, Strategy) | Pass | Pattern Annotations table lists Repository, Ports and adapters, Null Object, MVVM, Composition root. |
| 6 | Method signatures are traceable to Operation Contracts and/or design Sequence Diagrams | Pass | Method Traceability table maps every operation to OC-001 and SD-001 (the timer operation to SSD-001). |
| 7 | Class names and structure remain consistent with the Domain Model concepts they refine | Pass | The Class Table has a `Refines` column; names match the dictionary's IT terms. |
| 8 | No circular dependencies between classes/packages unless explicitly justified | Pass | Dependency Check states there are no cycles. |
| 9 | Dependencies between classes and packages point inward: domain classes do not depend on infrastructure, delivery or framework classes | Pass | Domain imports nothing; infrastructure and presentation point inward (Dependency Check). |

## Overall Verdict

Go — every Mandatory criterion passes. Reviewed by AI as stand-in for S01; not independent of the author.
