Struct TreeProv 

pub struct TreeProv {
    pub page_no: usize,
    pub bbox: [f64; 4],
    pub bottom_left: bool,
    pub charspan: [usize; 2],
}

docling’s ProvenanceItem for a tree item, written verbatim: the backend’s own geometry in the page’s units — a PPTX shape’s EMU box, whose pages entry is the slide size in EMU — rather than the 0–511 DocLang grid the flat Node::Located carries (which cannot round-trip those integers).

Fields

page_no: usize

1-based page (slide) number.

bbox: [f64; 4]

[l, t, r, b], exactly as docling computed them.

bottom_left: bool

docling’s coord_origin tag. MsPowerpointDocumentBackend builds a shape’s box with BoundingBox.from_tuple(…, BOTTOMLEFT) — which reads the tuple as (l, b, r, t), so the shape’s top EMU lands in b — a quirk the JSON keeps; a speaker note’s zero box is TOPLEFT (BoundingBox’s default).

charspan: [usize; 2]

[0, len(text)] in characters for a text item, [0, 0] for a table or picture.
