 # CI Workflows
 
-Placeholder for future GitHub Actions workflows.
+`ci.yml` runs on pushes to `main` and on pull requests. It cancels older runs for
+the same ref.
 
-Planned jobs:
+Jobs:
 
-- Go test for `agent/`;
-- `gofmt -l` and `go vet` for `agent/`;
-- `go test -race` for Go stage checkpoints or concurrency-heavy changes;
-- Python tests and migrations for `server/`;
-- PostgreSQL constraint tests for `server/`;
-- Agent-to-Server integration smoke;
-- TypeScript check, lint, and build for `web/`;
-- OpenAPI validation for `api/openapi.yaml`.
-- OpenAPI example payload validation for `examples/heartbeat.json` and `examples/event-batch.json`.
-- Docker Compose smoke for `/health`, `/ready`, `/metrics`, and example ingest.
+- `openapi` - lints `api/openapi.yaml` with pinned `@redocly/cli`.
+- `agent` - runs `gofmt`, `go vet`, `go test ./...`, and `go test -race ./...`.
+- `server` - installs with `uv`, then runs Ruff and pytest.
+- `web` - installs with npm, regenerates API types, then runs lint, typecheck,
+  build, and Playwright smoke.
+- `stack-smoke` - runs `deploy/smoke.sh` after server and agent jobs pass.
+
+Keep tool versions pinned in the workflow or in the component lockfiles. Do not
+replace pinned CI tools with `latest`.
