This is a fixed internal default and is not operator-configurable. Notes: -- `socketMode` is ignored in HTTP Request URL mode. -- Base `channels.slack.socketMode` settings apply to all Slack accounts unless overridden. Per-account overrides use `channels.slack.accounts..socketMode`; because this is an object override, include every socket tuning field you want for that account. -- Only `clientPingTimeout` has an OpenClaw default (`15000`). `serverPingTimeout` and `pingPongLoggingEnabled` are passed to the Slack SDK only when configured. +- The `channels.slack.socketMode` object, including `clientPingTimeout`, `serverPingTimeout`, and `pingPongLoggingEnabled`, is retired and is no longer read at runtime. `openclaw doctor` flags retired layout tuning knobs with a general notice rather than a per-key path. `openclaw doctor --fix` removes those three fields wherever they appear, at the channel root and under `accounts.`, and drops the `socketMode` object once it is empty. Any other key you added inside it is left alone, so delete it by hand. +- App messages and events remain application state, not transport liveness signals. - Socket Mode restart backoff starts around 2 seconds and caps around 30 seconds. Recoverable start, start-wait, and disconnect failures retry until the channel stops. Permanent account and credential errors such as invalid auth, revoked tokens, or missing scopes fail fast instead of retrying forever. ## Manifest and scope checklist
