 # Signals CI/CD & Local Stack (DEVOPS-SIG-26-001)
 
 Artifacts:
-- Compose stack: `ops/devops/signals/docker-compose.signals.yml` (Signals API + Mongo + Valkey + artifact volume).
-- Sample config: `ops/devops/signals/signals.yaml` (mounted into the container at `/app/signals.yaml` if desired).
-- Dockerfile: `ops/devops/signals/Dockerfile` (multi-stage build on .NET 10 RC).
-- Build/export helper: `scripts/signals/build.sh` (saves image tar to `out/signals/signals-image.tar`).
-- Span sink stack: `ops/devops/signals/docker-compose.spansink.yml` + `otel-spansink.yaml` to collect OTLP traces (Excititor `/v1/vex/observations/**`) and write NDJSON to `spansink-data` volume. Run via `scripts/signals/run-spansink.sh`.
-- Grafana dashboard stub: `ops/devops/signals/dashboards/excititor-vex-traces.json` (import into Tempo-enabled Grafana).

 # run stack
-COMPOSE_FILE=ops/devops/signals/docker-compose.signals.yml docker compose up -d

 - `Signals__Storage__RootPath` default `/data/artifacts`
 - Authority disabled by default for local; enable with `Signals__Authority__Enabled=true` and issuer settings.
