Struct DisplaySpan 

pub struct DisplaySpan {
    pub start: u32,
    pub end: u32,
    pub slot: String,
}

OA.5: the per-row style spans an Entry carries. PS.1: a styled run of a candidate’s display text.

start / end are BYTE offsets into display, half-open. A range that is out of bounds, inverted, or not on a UTF-8 boundary is dropped with a warning naming the source — one bad span must not cost a row its other runs, and must never panic the picker.

slot is a capture or theme-element name, resolved host-side through exactly the path a highlights.scm capture takes (name_to_style_with_theme): a builtin category (keyword, text.title.1, comment) wins first, and any other name resolves against the theme registry as a Style::Element — which is how a plugin’s own registered element (org.todo.WAITING) reaches a picker row. An unresolvable name renders unstyled rather than failing the row.

Naming a style rather than carrying one is deliberate, and follows annotation-custom.slot: a Style is a closed Rust enum plus an interned element id, and neither crosses an ABI meaningfully. A name does, and it means a guest’s picker row is coloured by the SAME vocabulary — and the same active colourscheme — as the buffer it came from.
