Six example models next to the three C4 ones: arc42 (Cinema Tickets, IoT Telemetry, Team Wiki) by section, ArchiMate (Insurance Claims, HR Onboarding, Logistics Tracking) by layer, each validated with 0 errors and 0 warnings. resolveRefs and the editor schemas now take ref: in workflow and dataflow nodes, sequence participants and lifecycle states, as the skill already did. Example tests check each framework's folders.

context: >
|
|
Cinema Wi-Fi drops when a full hall arrives. A scanner that
|
|
needs the server for every ticket stops the queue.
|
|
decision: >
|
|
The Ticket Service signs each QR payload (ticket id, show,
|
|
seat) with a private key. The scanner app verifies it with the
|
|
public key and queues check-ins until it is online again.
|
|
consequences: >
|
|
A forwarded ticket scans twice while offline; the second scan
|
|
is flagged when the queue syncs. Key rotation needs an app
|
|
update window.
