-# EDU ownership handoff
-
-## Current status
-
-EDU PR #1 merged at 2026-10-07 08:04:30 UTC. Main release `5094952464ce315130839303985fd04d721bc1f2` passed CI run 1585 and deploy run 1586. The workstation checkout `/srv/edu-master` is at that SHA. The release changed the application image digests:
-
-- Session keeper: `sha256:1e59473bd40fe4c22622017d808a8927a68788275fe073dc23d718c44b2fd5dd`
-- Webinar checker: `sha256:987d9bf0770272766523ea5b94c7f3f849175d737551d46591ae55e058cf9f12`
-
-The live workloads remain healthy in context `Default`, namespace `edu-master`. Both health and live probes return 200. Redis AUTH passes, session TTL is 1178 seconds, the delivery backlog is zero, all nine EDU alert rules are healthy, and the scrape target is UP. The unauthorized-pod Redis check passed. The Redis PVC UID and Secret UID and values, including the Fernet key, match their pre-release state.
-
-The homelab EDU active marker was present after the EDU deployment. It was moved to the private snapshot as `homelab-k8s-active.marker` while holding `/tmp/homelab-apply.lock`. The homelab checkout at `/srv/homelab` is at `5f9354b` and has the tracked marker deletion. Its deploy preflight blocks a dirty checkout until this removal is reconciled. Preserve private ignored configuration when syncing that checkout.
-
-The remaining homelab change is PR #105, branch `feat/edu-handoff-matrix`, based on `codex/ci-visible-checks`. Its eight protected checks passed. Renovate runs 1587 and 1588 passed. Image publishing was skipped for the PR. The EDU runtime changes are in PR #3 from `fix/handoff-runtime` to `main`; CI run 1589 is in progress. Those runtime changes have not been released.
-
-## Approval gate and next steps
-
-PR #99 must merge before PR #105 can target `main`. A merge attempt for PR #99 returned HTTP 405 because it needs one approval; the protected branch has `required_approvals=1` and whitelist approval is enabled. This approval gate prevents the remaining transfer steps.
-
-After the required approval:
-
-1. Merge PR #99.
-2. Retarget PR #105 to `main`. Complete CI and review, then approve and merge it.
-3. Under the homelab apply lock, sync `/srv/homelab` to the merged removal. Preserve private ignored configuration and keep the active marker removed. Confirm the deploy preflight is clean.
-4. Merge the EDU runtime PR after its CI and review pass. The main-push CI run must complete successfully before its exact SHA can deploy.
-5. Verify the new release SHA, image digests, workload health, Redis AUTH and TTL, backlog, PVC and Secret identity, and monitoring. Record the results in the EDU PR.
-
-`AUTODEPLOY=false` is explicitly configured. The EDU repository path and port secrets are confirmed, and `EDU_KUBE_CONTEXT=Default` is configured as a repository variable. Keep deployment and registry credentials outside Git. Never run both homelab and EDU deployment paths at the same time.
-
-## Change summary
-
-The homelab PR removes the EDU subtree, deployment and image selection, rollback and verification cases, route probes, Renovate references, and external-image exceptions. It adds a serial dynamic matrix for the three homelab images. Each job builds an image or reuses a matching immutable digest. The final job checks all image results and publishes full-SHA tags and the existing release artifact only after they pass. PRs do not publish images. The protected check names from PR #99 are preserved. PR #100's service-metrics work is independent of this handoff.
-
-The EDU runtime PR adds the Playwright service manifest, reconciles Redis storage and Secret reload annotations, and adds pre-apply Redis backup and identity checks. It verifies application endpoints, Redis AUTH, session TTL, metrics, and all nine vmalert rules. Rollback checks workload and application health and reports when manual recovery is needed. Its deployment guard rejects an unexpected or dirty checkout and refuses deployment while either legacy homelab EDU marker exists.
-
-## Rollback and limits
-
-The private snapshot is `/home/forust/.local/state/edu-master-deploy/handoff-20261007T080838Z` on the workstation. It contains the pre-handoff Redis RDB and recovery data. RDB checksum verification confirmed twelve keys. Keep the snapshot outside Git. For an EDU release failure, restore the saved Kubernetes resources and inspect application health. The rollback does not automatically restore the Redis RDB; restore old Redis data only when recovery requires it.
-
-For an ownership rollback, stop EDU deployment triggers first, restore the reviewed homelab source and marker, then reapply recorded immutable image digests. Verify both workload and application health. Never delete or recreate the Redis PVC.
-
-The initial EDU release and the homelab marker move are complete. PR #99 approval and merge, PR #105 retarget and merge, homelab checkout reconciliation, EDU runtime PR merge, and release of those runtime changes remain pending. Synthetic Telegram delivery and Alertmanager-to-Telegram notification were not tested.

 # Homelab CI/CD
 
 The native Gitea runner runs on **vps**; production runs on **workstation**.
-Compose, workflow, shell, Python, formatting, YAML, Dockerfile and Kubernetes
-checks appear as separate jobs. Jobs run on `homelab:host`, one at a time; the
-build waits for every check to pass. CI and deploy runs also show a summary with
-the release SHA, image build or reuse results, deploy mode, selected services,
-and image digests. Failed runs keep a summary of completed image builds, stage
-results, apply results, and recorded Kubernetes recovery. The final deploy
-summary is in the smoke job; earlier jobs show the state observed at that time.
-Apply success is separate from health and recovery. Update the installed
-workstation controller with `setup-workstation.sh` when no deploy is running.
-No job images or Kubernetes credentials
+Jobs run on `homelab:host`, one at a time. No job images or Kubernetes credentials
 are needed on the VPS. Builds use one pinned BuildKit helper container. CI and deploy are separate workflows.

+# EDU deployment ownership
+
+Application source and release builds: `forust/edu-master`.
+The homelab pipeline deploys `edu_master/k8s` and preserves explicit image digests.
+The application copies in this directory are legacy and are not build inputs.
+Do not publish EDU `prod` images from homelab or resolve releases from moving tags.
+
+For an EDU release, validate both images, select their digests in the keeper and
+checker manifests, and run the existing homelab validation/apply/verification
+helpers against this service. Keep the existing Secret and Redis PVC.
+Coordinate Redis authentication changes with both clients and all init/probes;
+keep a pre-rollout Redis backup and both previous compatible image references.
+The current HTTP checker does not depend on Playwright; check other consumers
+before removing the separate browser service.

@@ -15,3 +15,29 @@ The VictoriaMetrics Operator chart and its CRDs are installed before the
 Kubernetes manifests by the normal deploy workflow. On a cluster where the
 operator CRDs are not installed yet, CI skips the server-side dry-run of the
 `VMAgent` resource; the deploy installs the chart before applying that resource.
+
+## Application metrics
+
+The application ServiceMonitors use a 30s interval and a 10s timeout:
+
+- Headscale: the external Service points to the Compose host on port 19090.
+  A VMServiceScrape uses EndpointSlice discovery for this manually managed target.
+  The Compose configuration must bind metrics to `0.0.0.0:9090`.
+- NetBird: the combined server exports `/metrics` on port 9090. The existing
+  `server.metricsPort` setting enables the listener.
+- Gitea: `GITEA__metrics__ENABLED` enables `/metrics` on the HTTP port. The public
+  ingress excludes this path. The monitor uses the internal Service directly.
+- Immich: `IMMICH_TELEMETRY_INCLUDE=all` enables API and worker metrics on ports
+  8081 and 8082. The monitor scrapes both ports on each server replica.
+
+Deploy through the existing CI and deploy workflow. Gitea and Immich reload their
+ConfigMap changes through Reloader. Check the VMAgent targets after deployment
+and query `up{scraper="victoria",namespace=~"netbird|gitea|immich|headscale"}` in
+VictoriaMetrics. All targets should report 1.
+
+For rollback, revert the application metrics changes, run CI, and deploy the
+revert. Remove the three application ServiceMonitors and the Headscale VMServiceScrape explicitly: the deployment
+workflow applies manifests and does not prune removed resources.
+
+For Headscale rollback, remove its VMServiceScrape and Service label, restore the
+previous Compose metrics bind address, and restart only the Headscale service.
