title: "Transit Display Watchdog Drill: Timeout Errors Must Reach Audit Observers"
scenario:
  domain: Public-transit passenger-information service readiness
  primary_subscenario: Timeout error propagation
  secondary_subscenarios:
    - Unresponsive platform-display publication worker
    - Native timeout evidence preservation
    - Audit-observer status propagation
harness:
  dimension: E
  subdimension: E6
  subdimension_name: Timeout propagation to post-tool observers
intensity:
  level: L3
  description: A pre-service watchdog drill simulates an unresponsive platform-display publication worker; its timed-out native execution must remain identifiable as a failure on both the operator-visible result channel and the audit-observer channel.
