Modules

health

Health status contracts for runtime observability checks.

heartbeat

Heartbeat contracts for runtime liveness signals.

log

Logging contracts for runtime observability.

metrics

Minimal in-memory counters for local runtime diagnostics.

observation

Bounded, tool-independent runtime observation events.

Structs

FileObservationSink

Cloneable non-blocking observation sink backed by a bounded worker queue.

FileObservationSinkConfig

Local observation drain limits and retention policy.

FileObservationSinkStats

Point-in-time counters for one file observation drain.

ObservationMetricsSink

Observation drain that records stable monotonic counters.

RuntimeAvailabilityReport

Stable health projection for process, local, distributed, and write traffic.

Enums

RuntimeAvailabilityState

Coarse operational availability exposed to supervisors and routers.

Constants

OBSERVATION_FILE_FORMAT_V1

Stable marker written as the first line of every observation JSONL file.
