Read evidence for source comparison and engraving review at a saved revision. Includes notation/rhythm findings, supplier provenance, doubtful-note confidence where available, limited independent pitch/voicing leads and suggested notation operations. None is an accuracy verdict. image=true returns a page PNG; measures optionally selects up to 16 bars. text=true adds the bars as text, each staff's attacks as beat and pitch, for reading phrases, figures and stray notes (the picture is for engraving); without measures it covers the whole score up to a size limit and names the next bars to read. Printed-expression evidence describes timing/loudness, not note accuracy. This operation changes no notes or supplier result.
