 - **Public read-only hosts**: if a public host fronts a service that also exposes admin writes internally, add a Traefik route match like `Host(...) && (Method(GET) || Method(HEAD))` on the public edge instead of trusting the app to reject unsafe methods.
 - **Public read-write allowlist hosts**: if a public host accepts a tightly bounded write surface (e.g. bootstrap-JWT POST), pin the allowlist as `(Method(GET) || Method(HEAD) || Method(POST) || Method(OPTIONS))`. PUT/PATCH/DELETE must still 404 at the route. Track A's `updatecenter.iamworkin.lan` / `updates.iamworkin.lan` are the canonical example. The lint test enforces this invariant.
 - **Traefik VIP netpols**: when a `NetworkPolicy` allows `10.0.56.200`, also allow the post-DNAT backend ports (`8443` for TLS plus `8080` or `8000` for HTTP) or Calico will drop the rewritten flow.
+- **RemoteDesktop isolation**: `apps/fc-desktop/network-policies.yaml` intentionally keeps desktop pod egress to named CoreDNS, `intranet-web:5300/TCP`, and noc1 step-ca `10.0.56.10:9000/9443` only. Guacamole display egress is owned separately by `apps/guacamole/guacamole.yaml` through `guacd-desktop-egress` on `5901/TCP`.
 - **Auth-safe probes**: services behind API-key or global auth middleware should prefer `tcpSocket` probes unless `/health` is explicitly exempted before the middleware runs.
 - **ArgoCD must use internal Gitea URL**: `http://gitea-clusterip.gitea.svc.cluster.local:3000/bluejay/bluejay-infra.git`, not the external HTTPS URL (step-ca cert isn't trusted by ArgoCD). The `ApplicationSet` and any hand-created `Application` must both use the internal URL.

-# FlowerCore SignalControl platform notes
-
-This app owns the cluster web manager at `signalcontrol.iamworkin.lan` and documents the physical Pi pilot at `signal-a.iamworkin.lan` / `pirelay`.
-
-## mTLS enrollment pattern
-
-Do not install or restart anything from this repo. The intended pirelay pattern is the Pi-signage step-ca-agent shape:
-
- stable node identity: `pirelay`
- local private key and CSR generated on the node
- CSR submitted through the approved DeviceManagement/step-ca enrollment path
- client certificate and chain stored node-local under `/etc/flowercore/signalcontrol/mtls/`
- daily renewal timer, renewing only when fewer than 30 days remain
- certificate used for DM-agent to DM-web traffic and future SignalControl inter-service calls
-
-Secrets, enrollment codes, private keys, p12 passphrases, and OIDC client secrets stay out of Git.
-
-## Telemetry
-
-Monitoring manifests add a dedicated Prometheus job:
-
- `signalcontrol-pi-app`
- target `10.0.58.113:5200`
- path `/metrics/prometheus`
- labels `instance="pirelay"`, `host="signal-a.iamworkin.lan"`, `service="signalcontrol-pi"`
-
-Host metrics continue through the `edge-nodes` node_exporter target at `10.0.58.113:9100`.
-
-## Physical-control audit
-
-The app ships with `FlowerCore:SignalControl:PhysicalAudit:Enabled=false` and `ForwardingEnabled=false`. Enabling local audit creates a SHA-256 hash chain for physical-control mutations. Forwarding to `https://audit.iamworkin.lan/api/v1/audit/signalcontrol` requires flipping the forwarding gate separately.
-
-Telemetry reads and `/metrics` scrapes are not audited.
