+          # matter-server had NO probes — a hung or crashed server kept the
+          # pod Running while HA's WebSocket to it was dead. These probes fix
+          # that. `GET /` on :5580 returns 200 from the aiohttp server, so it
+          # is a real "the control server is up and answering HTTP" check —
+          # stronger than a bare tcpSocket. httpGet targets the pod IP, which
+          # is exactly where the server binds (--listen-address=$(POD_IP),
+          # PR #144), so this reaches the right socket.

+          # SCOPE, honestly: this catches server-down / hung / not-listening.
+          # It does NOT catch "fabric lost / 0 nodes" — that failure leaves
+          # the :5580 server (on eth0) answering while the net1 macvlan / SDK
+          # is broken, so no :5580 probe can see it. Closing that would need

+          # Matter fabric (~13 nodes re-subscribe over minutes, observed in
+          # #144). failureThreshold 5 x 30s = 2.5 min of sustained failure
+          # before a restart, so a transient blip never triggers fabric
+          # churn. The startupProbe (5 min budget) suspends liveness/readiness
+          # while the SDK loads the fabric and binds the socket.
