Struct WalResidue 

pub struct WalResidue {
    pub segment: WalSegmentId,
    pub first_frame_index: usize,
    pub frame_count: usize,
    pub reason: ResidueReason,
}

A stale WAL tail surfaced for forensics — NOT committed history.

Frames past the last COMMIT of a segment, frames after a salt reset that cannot be replayed into the current segment, or a header/page-size break: all are residue. The examiner weighs them; they are never part of a consistent snapshot.

Fields

segment: WalSegmentId

The segment the residue trails (the segment whose last commit it follows).

first_frame_index: usize

0-based frame index (within the file) of the first residual frame.

frame_count: usize

Number of residual frames.

reason: ResidueReason

Why these frames are residue rather than committed history.
