Struct SegmentEntry 

pub struct SegmentEntry {
    pub range: Range<Paddr>,
}

Per-Segment entry in the store. Represents one outstanding Segment<M> covering the contiguous physical range range.

Per exec SegmentOwner::relate_regions: every frame slot in range carries one forgotten reference for this segment — i.e., raw_count at the slot equals the number of SegmentEntrys covering it (see segment_cover_count). The frame’s ref_count >= 1 is bumped by the segment’s owning reference (one per frame); the segment does not hold a separate Frame handle, so the embedding’s frames map is unrelated to per-segment frame refcounting.

Multiple SegmentEntrys may overlap (e.g. after clone); each independently contributes +1 to every covered slot’s raw_count and ref_count.
