Modules

health

Health status contracts for runtime observability checks.

heartbeat

Heartbeat contracts for runtime liveness signals.

log

Logging contracts for runtime observability.

logging

Structured logging infrastructure shared by operational observers.

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.

FileObservationSinkPressure

Aggregate memory pressure for the file observation queue.

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

FILE_OBSERVATION_FLUSH_TIMEOUT

Default deadline shared by flush queue admission and acknowledgement.

MAX_FILE_OBSERVATION_QUEUE_BYTES

Maximum queued observation bytes, including the event currently being written.

MAX_FILE_OBSERVATION_QUEUE_ITEMS

Maximum item capacity accepted by the file observation queue.

OBSERVATION_FILE_FORMAT_V1

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