- Creds on disk: `ls -l ~/.clawdbot/credentials/whatsapp/<accountId>/creds.json` (mtime should be recent).
- Session store: `ls -l ~/.clawdbot/agents/<agentId>/sessions/sessions.json` (path can be overridden in config). Count and recent recipients are surfaced via `status`.
- Relink flow: `clawdbot logout && clawdbot login --verbose` when status codes 409–515 or `loggedOut` appear in logs. (Note: the QR login flow auto-restarts once for status 515 after pairing.)
- No inbound messages → confirm linked phone is online and the sender is allowed (`whatsapp.allowFrom`); for group chats, ensure allowlist + mention rules match (`whatsapp.groups`, `routing.groupChat.mentionPatterns`).
`clawdbot health --json` asks the running Gateway for its health snapshot (no direct Baileys socket from the CLI). It reports linked creds, auth age, Baileys connect result/status code, session-store summary, and a probe duration. It exits non-zero if the Gateway is unreachable or the probe fails/timeouts. Use `--timeout <ms>` to override the 10s default.
