…s→10s (PILOT-281) The primary heartbeats every 15s with a 5s write deadline, but the standby read deadline was 45s — creating up to a ~60s window where a standby cannot detect a silent primary failure (worst case: primary crashes immediately after a heartbeat, standby waits 45s). Tightening the read deadline to 30s and heartbeat to 10s reduces the stale-detect window to at most 30s, matching the documented intent in StartHeartbeat's comment. The 5s per-message write deadline is unchanged — that guards individual message hangs, not primary liveness. Closes PILOT-281
