Struct CommandSegment 

pub struct CommandSegment {
    pub slot: u32,
    pub slot_offset: usize,
    pub tape_start: usize,
    pub tape_end: usize,
    pub bounds: Rect,
    pub prev_recolors: Vec<u32>,
}

One retained stretch of a command’s recording, addressed by the retained snapshot’s tape range. The id is stable for the segment’s lifetime — renderer-side retained slots key on it, and it survives other segments dying.

Fields

slot: u32

The capture identity this segment’s content lives under: renderer retained slots key on the (command, slot) pair. Slot ids are allocated at partition, whose emission carries the capture content; split pieces inherit the parent’s slot and address into it, so a split never needs a recapture.

slot_offset: usize

This segment’s first record within the slot’s captured content.

tape_start: usize

tape_end: usize

bounds: Rect

Loose logical bounds at capture.

prev_recolors: Vec<u32>

Span-relative record offsets (ascending) this segment’s span recolored on the PREVIOUS verified frame. The renderer’s slot paint is a patched mirror, never rebuilt, so a record whose color returns EXACTLY to its capture value needs an explicit restore patch — pure diff-vs-snapshot emission would leave the mirror stale forever (see merge_color_restores).
