Dynamic Behaviour

State Machines

sm_operation_mode_state

This state machine defines high level operating mode transitions across Init Normal Warning Protective and Recovery and documents how warning events safety triggers and fault lifecycle events govern mode arbitration and output policy.

Sequence Diagrams

SEQ-001_Runtime_Event_Orchestration

Primary runtime interoperability sequence showing scheduler tick propagation through dispatcher fan-out and deterministic active-object processing order across monitoring control safety diagnostics and communication units.
