Tuning knobs. Defaults suit a LoRa mesh; a pager may shrink the windows.

Fields

reorder_grace_ms: u64

Grace period before acting on an inferred gap, absorbing reordering.

fragment_grace_ms: u64

Minimum quiet time after the newest stored fragment before repair of that reassembly may begin. Every fragment arrival defers repair by at least this much (and by twice the observed inter-fragment gap when that is larger), so an actively delivering message is never repaired mid-flight. Platforms should set this to several frame airtimes.

group_jitter_ms: u64

Maximum extra randomized delay for channel-group repair requests.

max_auto_repair_gap: u8

Largest forward gap repaired automatically (spec bound: 8).

min_request_interval_ms: u64

Minimum interval between resend requests on one stream.

max_requests_per_tick: u8

Maximum resend requests transmitted per tick across all streams.

max_repair_attempts: u8

Maximum automatic request attempts per missing frame.

reassembly_ttl_ms: u64

Reassembly lifetime before a partial message is finalized.

request_retry_ms: u64

Interval between repair attempts for the same frame.

coalesce_window_ms: u64

Window in which duplicate resend requests are coalesced.

fragment_notify_ms: u64

Latency after the first fragment of an incomplete message before the host is notified anyway (the sooner of this deadline and completion).

sentinels: RenderSentinels
