 - CLI/Status: make the “More” footer shorter and easier to scan (newlines + context-aware suggestions).
 - Docs/FAQ: make `clawdbot status` the first diagnostic step (and point to `status --all` for pasteable reports).
 - CLI/Status: format non-JSON-serializable provider issue values more predictably.
+- Gateway/Heartbeat: deliver reasoning even when the main heartbeat reply is `HEARTBEAT_OK`. (#694) — thanks @antons.
