+# fc-signage-appletv
+
+Apple TV signage is a sealed appliance running the `FlowerCore.Signage.Agent.AppleTv` tvOS app per ADR-134.
+
+This ApplicationSet entry is documentation and inventory metadata only. It intentionally creates no `Deployment`, `Service`, or `Pod`.
+
+The Apple TV app connects outbound to existing FC.Signage.Web surfaces:
+
+- `https://signage.iamworkin.lan/hub/signage` for SignalR live status.
+- `GET /api/v1/nodes/{nodeId}/state` for the 30 second polling fallback.
+- `POST /api/v1/nodes/register` and `POST /api/v1/nodes/{nodeId}/enroll` for pairing and mTLS enrollment.
+- `POST /api/v1/nodes/{nodeId}/heartbeat` for metrics, current content identity, and local audit excerpts.
+
+Distribution is via Apple Developer Enterprise Program or TestFlight plus FC.Distribution / UpdateCenter publishing once Apple credentials are available.

+    - Heartbeat: POST /api/v1/nodes/{nodeId}/heartbeat

+    This placeholder gives ArgoCD and inventory dashboards a first-class
+    Apple TV signage app entry without creating runtime pods.

+# FlowerCore Signage Pi Player
+
+Phase 1 Raspberry Pi signage player packaging for Chromium kiosk deployments.
+This bundle is intentionally air-gap friendly: systemd units, shell scripts,
+udev rules, and Chromium managed policy are all checked into the repo and are
+installed by `FlowerCore.Puppet`.
+
+## Scope
+
+- Bootstrap a stable node identity and mTLS client certificate.
+- Launch Chromium in kiosk mode against `FC.Signage.Web` player routes.
+- Restart the kiosk on HDMI hotplug.
+- Renew mTLS certificates daily when fewer than 30 days remain.
+- Detect display capabilities at boot, daily, and on HDMI hotplug.
+
+Phase 2 native Avalonia rendering is documented separately in Notes and remains
+deferred.

+# github-runner
+
+ArgoCD-managed repo-scoped Linux GitHub Actions runners for FlowerCore.
+
+`astoltz` is a GitHub user account, not an organization, so each repository
+needs its own runner registration. The existing Common runner remains
+`Deployment/github-runner`; Sprint 29 adds one single-replica Deployment for
+each top Linux-cost repo:
+
+- `FlowerCore.Puppet`
+- `FlowerCore.Signage`
+- `FlowerCore.DMS`
+- `FlowerCore.Telephony`
+- `FlowerCore.Print.Web`
+- `FlowerCore.Chat`
+- `FlowerCore.MySQL`
+- `FlowerCore.Kiosk.Linux`
+
+Each runner uses `myoung34/github-runner:latest`, `EPHEMERAL=true`, and labels
+`self-hosted,linux,fc-build-linux`. The shared `github-runner-token` Secret is
+synced from the existing 1Password item `GitHub PAT (Runner Registration)` and
+is consumed as `ACCESS_TOKEN`.
+
+Do not `kubectl apply` this app over ArgoCD. Merge to `main`, let
+`infra-github-runner` sync, then verify from `noc1`:
+
+```bash
+kubectl -n github-runner get deploy,pods,pvc
+
+for repo in FlowerCore.Puppet FlowerCore.Signage FlowerCore.DMS FlowerCore.Telephony FlowerCore.Print.Web FlowerCore.Chat FlowerCore.MySQL FlowerCore.Kiosk.Linux; do
+  gh api "/repos/astoltz/$repo/actions/runners" \
+    --jq '.runners[] | select((.labels[].name == "fc-build-linux") and (.status == "online")) | {name,status,busy,labels:[.labels[].name]}'
+done
+```
+
+`LinuxRunnerOffline` is declared in `apps/monitoring/noc-monitoring.yaml` and
+fires when any Common or top-8 Linux runner deployment has no available replica
+for 10 minutes.

+# GitHub Actions self-hosted Linux runner fleet

+# ArgoCD owns this namespace. Do not kubectl-apply ad hoc runner changes over
+# it; update this manifest and let the bluejay-infra ApplicationSet reconcile.
+#
+# astoltz is a GitHub user account, not an org, so runners must be repo-scoped.
+# Each Deployment below registers exactly one ephemeral myoung34/github-runner
+# instance against one private FlowerCore repo using the shared PAT from the

+#
+# Current shape:
+#   - Common runner preserved from the phase-2 pilot.
+#   - Sprint 29 top-8 Linux-cost repos added first:
+#     Puppet, Signage, DMS, Telephony, Print.Web, Chat, MySQL, Kiosk.Linux.
+#
+# Security:
+#   - No ClusterRole / ClusterRoleBinding.
+#   - ServiceAccount has no K8s API privileges.
+#   - Self-hosted runners are for private repos and trusted branches only.
+#   - Fork pull-request approval must remain required in GitHub repo settings.
