# Distributed Tracing

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

## Repair

- Refactored by: Add Tracing Middleware, Propagate Context
- Detected by: broken traces, missing spans
- Violated by: service calls without trace propagation
- Measured by: trace completeness, span coverage
- Enforced by: observability policy

## requires
