Safety monitor for fault latching and fail-fast process termination.

CuSafetyMon is designed for safety-critical deployments where "keep running" is less important than deterministic fault containment.

Behavior:

  • Maintains a CopperList heartbeat (process_copperlist) and exits if no progress is observed within copperlist_deadline_ms.
  • Consumes the runtime execution probe to report the last known (component_id, step, culistid) when a lock is detected.
  • Registers with Copper's shared panic hook and turns panics into explicit process exit codes.
  • Latches runtime errors (process_error) as shutdown faults with their own exit code. The process_error index is a monitored component index into CuMonitoringMetadata::components().

Config (monitor config map keys):

  • copperlist_deadline_ms (u64, default: 1000)
  • watchdog_period_ms (u64, default: max(deadline/4, 10))
  • exit_code_shutdown (i32, default: 70)
  • exit_code_lock (i32, default: 71)
  • exit_code_panic (i32, default: 72)

Implementation is split by target profile:

  • std_impl: full watchdog/panic/exit behavior.
  • nostd_impl: compile-only placeholder (behavior intentionally deferred).
