| 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. |
