Struct CheckpointAdvice 

pub struct CheckpointAdvice {
    pub through_step_seq: WireU64,
    pub usage: TailUsage,
    pub bounds: TailBounds,
}

The soft-watermark crossing of §12.3, with the numbers that justify it.

It is advice and nothing more: no state moves, no input is refused, and ignoring it costs exactly one CheckpointRequired rejection later — the retryable one. That is the difference between this and the overflow latch it replaces, which turned “the tail got long” into a permanent refusal with no way back.

Fields

through_step_seq: WireU64

usage: TailUsage
