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.

OperationalPeerV1

One opaque peer’s independent transport, health and applied progress observations.

OperationalProjectionV1

Independent bounded operational projection for an authenticated partition.

RuntimeAvailabilityReport

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

Enums

DeliveryPhaseV1

Queue phase reported explicitly by the delivery owner.

DiscoveryScopeV1

Scope of discovery. Known peers alone never prove complete discovery.

OperationalStateV1

Observation state; absence of evidence never becomes a health claim.

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.

MAX_OPERATIONAL_PEERS_V1

Maximum peers in one operational projection.

OBSERVATION_FILE_FORMAT_V1

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