David noticed: PPTX files should be handled natively, not transcribed
David rejected a proposal to extract text from PPTX files and write notes from it, insisting the correct solution was conversion or native MIME type support.
When an agent suggested handling PPTX lecture materials by extracting their text content and "writing notes from the extracted content", David rejected this flatly:
no, absolutely not. what do you mean write notes from the extracted content? why not just convert it to a pdf? or why cant the system handle PPTX files? arent they a MIME type?
The principle was that the content integrity of source materials must be preserved — converting a presentation to PDF (or supporting PPTX as a native MIME type) is the right engineering path. Paraphrasing source material as a workaround produces lower-quality notes and loses formatting/visual information that belongs in the lecture record.
