Classes
class	CircuitBreaker
	Zero-allocation Circuit Breaker pattern for isolating faulty handlers or peripheral links. Thread-safe lock-free state transitions. More...

struct	CircuitBreakerTrippedEvent
	Dispatched when a CircuitBreaker detects repeated failures and trips open. More...

struct	DeadlineMissedEvent
	Dispatched when an event handler or task misses its real-time deadline budget. More...

class	HeartbeatMonitor
	Zero-heap multi-service heartbeat tracker for safety-critical execution. Thread-safe for concurrent heartbeat signals and supervisory health checks. More...

class	WatchdogService
	Multi-threaded background safety service executing periodic heartbeat supervision. Automatically verifies monitored task deadlines and dispatches WatchdogTimeoutEvent to the main event bus on violations. More...

class	WatchdogSupervisor
	Dedicated safety supervisor monitoring subsystem heartbeats and controlling watchdog refresh. Compatible with hardware IWDG (STM32, ESP32, nRF), RTOS Task Watchdogs, and POSIX watchdogs. Zero dynamic heap allocations, zero threading overhead. More...

struct	WatchdogTimeoutEvent
	Dispatched when a monitored service fails to deliver its heartbeat within its timeout window. More...

Enumerations
enum class	CircuitState : uint8_t { Closed , Open , HalfOpen }
	Circuit Breaker operational state. More...

◆ CircuitState

strong

Circuit Breaker operational state.

Enumerator
Closed	Normal operation: all calls execute.
Open	Tripped/Faulty: calls are fast-failed without execution.
HalfOpen	Recovery probing: allowing a single canary call to verify health.
