ADR-007: Observability Baseline

Decision

Adopt OpenTelemetry (traces), Prometheus (metrics), structured JSON logs (Loki/ELK). Correlation via traceId + correlationId across events.

Metrics Governance

Service must expose: request latency histogram, error counter, domain metric(s).

Tracing

Span for each external call; event spans carry eventType attribute.
