- Per-subscriber max_polling_interval (default 5s) caps the idle backoff
- _consume doubles sleep on consecutive empty cycles, ±50% jitter, resets on first hit
- Exception sleep replaced with 1/2/4/8/16/30s backoff plus jitter, resets on success
- _get_msgs returns count fetched or -1 for back-pressure (limiter saturated)
