Helpdesk Event Limitations

Events​

  • Not implemented: no Helpdesk domain-event layer.
  • Partial: ten lifecycle names share one broad snapshot contract rather than event-specific contracts.
  • No attachment-removed, general ticket-updated, category, priority or configuration events were found.

Integration​

  • Not implemented: no Helpdesk hosted relay or verified processor invocation.
  • Document Service and Gateway are synchronous boundaries, not event consumers.
  • No external Helpdesk consumers were found.

Delivery​

  • Current automatic Helpdesk-to-broker delivery is Not implemented.
  • No publisher confirmations, terminal dead-letter status, cleanup, retention, claim/lock, attempt ceiling or backoff exists in the verified Helpdesk path.

Ordering​

  • Only a global OccurredAtUtc query order exists.
  • There is no per-ticket sequence or durable ordering guarantee.

Correlation​

  • Contract fields exist, but Helpdesk populates correlation and causation with null.
  • Request-to-notification lineage is incomplete.

Notifications​

  • Notification Service covers all ten names, but delivery depends on relay, recipient data, preferences, templates and channel sender behavior.
  • The publisher contains an administrator placeholder address; production suitability Requires confirmation.

Compatibility​

  • Compatibility create and status patch emit events; general update and backfill do not.
  • Generic status changes do not preserve lifecycle-specific event semantics.

Testing​

  • Dedicated Helpdesk event, relay, replay, duplicate and end-to-end tests were not found.
  • Poison-message and recovery exercises are not verified.
