## Checklist Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | Method signature is complete: operation name, parameter types, and return type | Pass | Each contract gives name, parameter list and return type (`startStudySession(): CardDto | None`). |
| 2 | Preconditions explicitly list required state before execution | Pass | Preconditions are listed per contract. |
| 3 | Postconditions explicitly describe resulting state using Larman's "instance created/associated/attribute modified" style | Pass | Postconditions use created / associated / destroyed / attribute set wording. |
| 4 | Exceptions and error conditions are documented, including the triggering precondition failure | Pass | Each contract has an Exceptions table with the failing precondition. |
| 5 | Operation is explicitly traceable to a single SSD message | Pass | Each contract traces to exactly one SSD message; the timer step has none and says so. |
| 6 | Contract avoids specifying implementation/algorithmic details (declarative, not procedural) | Pass | Postconditions are declarative. |
| 7 | Cross-references the Domain Model classes/associations affected by pre/postconditions | Pass | Domain Model concepts and IT terms are cited per contract. |

## Overall Verdict

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