Struct Annotation 

pub struct Annotation {
    pub text: String,
    pub spans: Vec<DisplaySpan>,
}

HB.5: the row an Entry hangs below itself. HB.5: one line hung below a row, and how it is coloured.

One line rather than a list: the consistency graph is one row, and heights and scroll interactions are not worth inventing for a consumer that does not exist. A list<annotation> is the obvious widening.

Fields

text: String

The line’s text, rendered as-is. Not an excerpt of anything — this is the one place a scan source draws content of its own.

spans: Vec<DisplaySpan>

Byte spans into text (NOT into the row’s source line, which this is not part of), so a guest’s own registered elements (org.habit.overdue) reach the row with the active colourscheme applied and no colour crosses the boundary.

A slot here names a THEME ELEMENT, and only that. entry.spans also accepts tree-sitter capture names (keyword, string), because those stay a semantic style the cells worker colours at paint time — but a virtual row’s cells carry a baked colour, so the annotation resolves its slots when the row is built and a capture name has nothing to resolve against. An unknown slot renders in the renderer’s default foreground rather than failing the row.

Validated per span like entry.spans: a bad one costs itself, and an annotation whose spans are all bad still renders its text. A row must never lose its annotation because a decoration was malformed.
