PowerPoint answers can now be cited by slide. A deck's chunks came back
with no attribution at all — no slide number, no title, and MarkItDown's raw
slide markers sitting in the chunk text — because the pipeline recognises
<!-- page: N -->and MarkItDown writes<!-- Slide number: N -->, so the
marker was never seen as one and fell through as ordinary paragraph text.Translating it at the engine boundary fixed the attribution but not the
citation: slide content is sparse, so the token-budgeted chunker packed 55 of
a 60-slide deck into one chunk. Accurate, and no use to anyone. A deck is now
chunked one slide at a time, the same way Docling supplies its own chunks for
PDFs, so 60 slides yield 60 chunks each naming its slide and title. An
oversized slide still splits normally.Speaker notes were already extracted and are searchable. Diagrams are not: a
slide with three boxes and two arrows gives three labels, and the arrows are
lost. Images inside slides are not read at all. Both are documented.
