Summary

When gateway.auth.mode is set to none, the Gateway's own internal RPC probe fails with:

gateway closed (1008): device identity required
RPC probe: failed

This causes a cascading failure chain:

1. All exec approval followup dispatches timeout after 60s
2. Frontend detects seq-gap → triggers websocket reconnect
3. Reconnect pulls history from server, which may not have persisted the streaming assistant reply yet
4. The reply appears to the user then disappears ("flash then vanish")

Expected behavior

auth.mode=none should still allow the Gateway's own internal RPC probe and followup dispatch to function, since these are internal operations that don't need external authentication.

Actual behavior

Internal RPC probe is rejected with 1008: device identity required, making the entire followup pipeline non-functional.

Workaround

Set gateway.auth.mode to token (which auto-generates a token). This immediately resolves the issue.
