Module contract 

Stable Phase 219 observability contract names.

These constants mirror docs/observability-metric-contract.md and docs/observability-event-trace-contract.md. Producers should use these names instead of repeating string literals so metrics, events, traces, dashboards, and docs stay aligned.

Constants

FORBIDDEN_DEFAULT_METRIC_LABELS

Default production Prometheus labels must not use these fields.

PHASE_219_EVENT_NAMES

Required event names for Phase 219 lifecycle and decision streams.

PHASE_219_METRIC_FAMILIES

Required dimensional metric families for Phase 219 producers.

PHASE_219_SPAN_NAMES

Required span names for Phase 219 admission-to-lease traces.

STABLE_METRIC_FAMILIES

Existing aggregate metric families rendered by the current PrometheusExporter.

Functions

is_forbidden_default_metric_label
