1. **Backend made responsive (2026-08-23, `4d70b25`)** — user-visible lag fixed: 1. **Publish latency trimmed further (2026-08-23, `cb23a5e`)** — after the concurrent
IPC fix, rename still took ~10 s: `wait_for_connection` always burned its full
timeout when any relay was unreachable, and the dead relay's send burned 8 s.
Removed the global connection wait (`send_event` waits for writability itself) and
capped sends at 6 s. Typical rename now completes in ~1–3 s even with one dead
relay. If still too slow, next step is fully background publishing.
