 - TTS/status: show configured TTS model, voice, and sanitized custom endpoint in `/status`, preserve OpenAI-compatible TTS instructions on custom endpoints, and retry empty Microsoft/Edge TTS output once. Addresses #46602, #47232, and #43936. Thanks @leekuangtao, @Huntterxx, and @rex993.
+- Agents/Gateway: steer agent-driven config edits and restarts through the owner-only `gateway` tool, document `config.schema.lookup` as the field-doc source, and warn against using `gateway stop && gateway start` as a restart substitute on macOS. Fixes #71929. Thanks @ygc3817922006-sketch.

+- Use `gateway restart` to restart a managed service. Do not chain `gateway stop` and `gateway start` as a restart substitute; on macOS, `gateway stop` intentionally disables the LaunchAgent before stopping it.
 - When token auth requires a token and `gateway.auth.token` is SecretRef-managed, `gateway install` validates that the SecretRef is resolvable but does not persist the resolved token into service environment metadata.
 - If token auth requires a token and the configured token SecretRef is unresolved, install fails closed instead of persisting fallback plaintext.
 - For password auth on `gateway run`, prefer `OPENCLAW_GATEWAY_PASSWORD`, `--password-file`, or a SecretRef-backed `gateway.auth.password` over inline `--password`.
