Wire OTel metrics into the four remaining .NET services (acl, domain, event-subscriber, projection-api) exactly as the BFF: ASP.NET Core + HttpClient instrumentation + the built-in System.Runtime meter, exposed at /metrics via the Prometheus AspNetCore exporter (ADR-0024). Prometheus scrapes one job per service; Grafana ships a pre-built 'Request path — golden signals' dashboard (traffic/errors/latency/saturation). A verify-metrics CI step proves the endpoints are scraped end to end.

# S-16c (#124): assert the golden-signal metrics pipeline works — the .NET services expose
|
|
# /metrics and Prometheus scrapes them — against an ALREADY-RUNNING full stack. Runs the
|
|
# driver in a python:3-slim container on the stack network (services reached by container IP;
|
|
# the runner can't reach published ports — gitea-actions-gotchas.md §5/§6). Does NOT manage
|
|
# the stack lifecycle.
