## Checklist Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | Message passing strictly follows UML sync/async/return arrow syntax | Pass | Solid arrows for calls and dashed arrows for returns. |
| 2 | GRASP/GoF patterns applied and explicitly annotated where used (e.g. Controller, Observer, Mediator, Factory) | Pass | Controller, Pure Fabrication, Creator, Facade and Protection from variations are annotated. |
| 3 | Lifelines show activation bars matching actual processing time/call nesting | Pass | Activations follow the call nesting. |
| 4 | Object creation and destruction shown with correct UML notation (`create`/`destroy` messages, X on lifeline) | Pass | Creation and destruction are shown for every transient object. Fixed during this review: creation and destruction of the two host clients were missing. |
| 5 | Diagram realizes the postconditions of a specific Operation Contract | Pass | The coverage tables map every postcondition P1 to P4 and P1 to P13 to a message. |
| 6 | Responsibility assignment favors low coupling/high cohesion (no god-object receiving all messages) | Pass | The controller only sequences; work sits in the helpers. |
| 7 | Loop, alt, and opt combined fragments used correctly for conditional/repeated behavior | Pass | `alt` for the license choice, `opt` for the optional GitHub steps. |
| 8 | Each exception of the realized Operation Contract is shown as an `alt` or `opt` fragment, or its absence is justified | Pass | Failure paths are not drawn and the Responsibility Check says why. |

## Overall Verdict

Go — All mandatory criteria pass after the fix noted at criterion 4. Author and reviewer are the same person for now (S01 and S02 are both held by the Maintainer), so the framework's independence rule is not met; re-review when a second person takes S02.
