+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.

+# 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 Actions self-hosted Linux runner — Phase 2 K8s deployment
+#
+# Phase 1 (current): BLUEJAY-WS registered manually as a Windows runner
+#   with label "fc-build-windows" via config.cmd (see docs/infrastructure/
+#   self-hosted-runner-fleet.md §WPF Build Runner).
+#
+# Phase 2 (this file): ephemeral Linux runner in RKE2 for non-WPF builds
+#   (Blazor Server, class libraries, operators, integration tests). Reduces
+#   billing for ubuntu-24.04 jobs that run on GitHub-hosted runners today.
+#
+# Runner image: myoung34/github-runner:latest
+#   EPHEMERAL=true — each pod runs exactly one job then exits; the
+#   Deployment controller immediately recreates it and re-registers.
+#   Prevents job queue starvation when two jobs overlap.
+#
+# NuGet cache: 5Gi Longhorn RWO PVC mounted at /home/runner/.nuget/packages
+#   Persists NuGet packages across ephemeral pod restarts (not shared across
+#   simultaneous runner pods; single-replica constraint below).
+#
+# Credentials:
+#   OnePasswordItem "GitHub PAT (Runner Registration)" → Secret
+#   github-runner-token with field "credential" used as RUNNER_TOKEN.
+#   Operator must create/rotate the 1P item manually; registration tokens
+#   expire after 1h — use a fine-grained PAT with Administration:read/write
+#   scope on the target repos, or a re-registration script. See
+#   docs/infrastructure/self-hosted-runner-fleet.md §Security.
+#
+# Security model:
+#   - No ClusterRole / ClusterRoleBinding — runner has no K8s API access.
+#   - securityContext: runAsNonRoot with read-only root filesystem where
+#     possible (runner image needs /tmp and /home/runner writable).
+#   - Fork pull-request approval required on the GitHub repo settings.
+#   - RUNNER_ALLOW_RUNASROOT=false is the default.
+#
+# Cost: Phase 2 eliminates GitHub-hosted ubuntu-24.04 billing; break-even
+#   vs electricity is ~1 000 min/month at current TOU rates.
+#
+# Node placement: rke2-server (10.0.56.11) only — Longhorn RWO PVC must
+#   land on the same node as the volume, and the server node has the most
