 <AccordionGroup>
   <Accordion title="Startup behavior">
     - Refuses to start unless `gateway.mode=local` is set in `~/.openclaw/openclaw.json`. Use `--allow-unconfigured` for ad-hoc/dev runs; it bypasses the guard without writing or repairing config.
+    - When startup finds a repairable invalid config, an interactive terminal offers to run `openclaw doctor --fix` and retries startup once after consent. Non-interactive runs never repair automatically; they print the command instead. If the repaired config is still invalid, startup remains stopped.
     - `openclaw onboard --mode local` and `openclaw setup` write `gateway.mode=local`. If the config file exists but `gateway.mode` is missing, that is treated as damaged/clobbered config and the Gateway refuses to guess `local` for you — re-run onboarding, set the key manually, or pass `--allow-unconfigured`.
     - Binding beyond loopback without auth is blocked.
     - `--bind` values `lan`, `tailnet`, and `custom` resolve over IPv4-only paths today; IPv6-only bring-your-own-host setups need an IPv4 sidecar or proxy in front of the Gateway.
