Summary OpenClaw: Gateway operator.write Can Reach Admin-Class Channel Allowlist Persistence via chat.send The shared `/allowlist` command persists channel authorization config through `writeConfigFile(...)` but does not re-validate gateway client scopes for internal gateway callers. Because `chat.send` is intentionally reachable to `operator.write` callers and still creates a generic command-authorized internal context, an authenticated write-scoped gateway client can indirectly mutate channel `allowFrom` and `groupAllowFrom` policy that direct `config.patch` correctly reserves to `operator.admin`. This is not just a generic code smell. The current code already shows the intended boundary by adding sink-side internal admin checks to shared `/config` and `/plugins` writes, but `/allowlist` was left behind.
