 "Agent health check: OK". If `degraded` or `critical`, report the specific
 failures and their severity.
 
+**Mandatory report legs** (2026-09-17 decision, 1295.msg): Every report line
+MUST include one clause per check leg, in every state: healthy, degraded/warn,
+skipped, or failed. A missing leg must never look the same as a healthy leg.
+Required legs and their templates in every state:
+
+- `LiteLLM keys: 4/4 (tanko, abiba, koby, koonimo) valid`
+  - degraded: `LiteLLM keys: 2/4 (tanko valid; koby invalid; koonimo valid; abiba probe-failed: 192.168.68.116:4000 timeout)`
+  - skipped: `LiteLLM keys: SKIPPED (LiteLLM router unreachable)`
+- `GPU ports: 3/3 (rtx3090, rtx5070, strixhalo) healthy`
+  - skipped: `GPU ports: SKIPPED (no SSH access to GPU hosts)`
+  - degraded/warn: `GPU ports: 2/3 (rtx3090 healthy; rtx5070 degraded: svc=inactive, port owned by 1234; strixhalo healthy)`
+  - failed: `GPU ports: 2/3 (rtx3090 healthy; rtx5070 probe-failed: 192.168.68.110:9400 timeout; strixhalo healthy)`
+  - The GPU leg has six non-healthy states the code can produce:
+    (i) `gpu-unreachable:{host}` — SSH probe failed;
+    (ii) `gpu-no-port:{label}` — SSH worked, port not listening;
+    (iii) `gpu-ghost:{label}:{pid}` — unit inactive, port owned by another pid;
+    (iv) unit not active, MainPID empty or port owned by MainPID — svc inactive;
+    (v) unit active, /health body contains "error" — error response;
+    (vi) unit active, /health body unrecognised — unknown health.
+    In every case the failing host and reason must be named.
+- `CTs: 4/4 running (tanko, abiba, koby, koonimo)`
+  - degraded: `CTs: 3/4 (tanko running; abiba running; koby probe-failed: ssh root@192.168.68.129 timeout; koonimo running)`
+  - skipped: `CTs: SKIPPED (SSH access unavailable)`
+- `Vault secrets: 3/3 present`
+  - degraded: `Vault secrets: 2/3 (tanko present; koby present; koonimo missing)`
+  - skipped: `Vault secrets: SKIPPED (vault not configured)`
+
+The compact form in the summary line is acceptable (e.g. `rtx5070 timeout`) as
+long as the host is identifiable from context; the full `probe-failed: <target>
+<kind>` form is required when a leg reports a failure in the detail section.
