✅ Soak Testing — Sustained traffic load monitoring memory leaks via tracemalloc.
✅ Stress-to-Knee Testing — Automated user ramp-up finding the exact breaking point where p99 latency or error rates breach thresholds.

Future Roadmap

EventBus & Outbox

Distributed Tracing Spans — Exporting OpenTelemetry trace context across gRPC and external HTTP service boundaries.
Event Schema Registry — Central schema registry for event payload deprecations.

Platform
