+| --- | --- | --- | --- |
+| 1 | Actors are defined with correct UML stereotypes (e.g. `<<System>>`, `<<Actor>>`) | Pass | Actor <<Actor>> and boundary <<System>> stereotyped. |
+| 2 | System boundary is clearly drawn and labeled | Pass | Boundary rectangle labelled Higher Lower. |
+| 3 | Include/extend relationships are used correctly per UML 2.5.1, not as generic "uses" arrows | Pass | No include/extend used; the Relationships section says so. |
+| 4 | Every actor participates in at least one use case (no orphan actors) | Pass | Player is in Play a Game. |
+| 5 | Diagram is traceable to a documented stakeholder need | Pass | Player traces to S01 and S02 in SA-001. |
+| 6 | Use case names are verb phrases describing actor goals, not internal system operations | Pass | Play a Game is an actor goal. |
+| 7 | Diagram is free of implementation detail (e.g. UI widgets, database tables) (Optional) | Pass | No UI or storage detail. |
+| 8 | Actor and use case naming is consistent with corresponding Use Case and User Story documents (Optional) | Pass | Names match US-001 and UC-001. |
+
+## Overall Verdict
+
+Go — all applicable criteria pass. Reviewer and author are both S01: the project has a single participant, so the framework's author/reviewer separation cannot be met. S01 accepted this deviation when requesting acceptance (2026-10-04).
