# Observability

Record: `arch:observability`
Kind: quality-attribute
Layer: [Observability](https://banes-lab.com/records/layer/observability.md)
Severity: mandatory for production systems
Scope: service, system, runtime
Canonical: https://banes-lab.com/ontology#arch-observability

## Repair

- Refactored by: Add Logs/Metrics/Traces
- Detected by: missing telemetry around critical paths
- Violated by: production behavior cannot be inferred
- Measured by: telemetry coverage, MTTR
- Enforced by: observability standards
