AdvisoryAI), archive completed scheduler UI sprint, update module
architecture docs (router, graph, jobengine, web, integrations),
and add Gitea entrypoint script for local dev.

+## Live Catalog Workflow
+
+The shipped operator workflow is now backed by the Integrations service rather than CLI sample data.
+
+### Provider Discovery
+
+- `GET /api/v1/integrations/providers` returns live provider metadata from the loaded connector plugins.
+- Default responses hide test-only providers such as `InMemory`.
+- Each provider entry now advertises:
+  - `isTestOnly`
+  - `supportsDiscovery`
+  - `supportedResourceTypes`
+
+### Resource Discovery
+
+- `POST /api/v1/integrations/{id}/discover` is the supported discovery contract.
+- Registry providers discover `repositories` and `tags`.
+- SCM providers discover `projects` and `repositories`.
+- CI/CD providers discover `jobs` and `pipelines`.
+- Object storage providers such as `S3Compatible` participate in the live catalog and health/test flows, but do not currently advertise discovery.
+- Unsupported resource types return `400` with the provider's supported resource types.
+
+### CLI Management Surface
+
+The `stella config integrations` command group manages the live catalog end-to-end:
+
+```bash
+stella config integrations providers
+stella config integrations list
+stella config integrations create --name local-gitlab --type scm --provider gitlabserver --endpoint http://gitlab.stella-ops.local:8929 --authref authref://vault/gitlab#access-token
+stella config integrations create --name local-minio --type objectstorage --provider s3compatible --endpoint http://minio.stella-ops.local:9000
+stella config integrations test <integration-id>
+stella config integrations discover <integration-id> --resource-type projects
+```
+
+Deprecated `stella integrations *` routes are preserved as aliases and forward to `stella config integrations *`.
