File > Export Notes as CSV... writes every comment and drawing to a flat CSV, one row per note: frame, timecode, type, content, color, x, y, done, timestamp. - utils/notescsv.py is pure (no Qt), so the row building is tested on its own. Rows are ordered by frame ascending; within a frame the comments come first, then the drawings in the order they were made. - Coordinates are the normalized 0-1 image-space values the annotations are already stored in, so a note stays meaningful regardless of the resolution it was made at. Blank means not applicable: a scribble has no text, a frame-level comment has no pin. - Text annotations carry their words into the content column; pencil strokes anchor on their first point, shapes on their start corner. - An unusable frame rate degrades the timecode to a frame label (f0042) rather than failing the export. Bad metadata must not cost a supervisor their notes. - The file is opened with an empty newline argument, else the csv module emits CRLF twice per row on Windows and every other line of the exported file comes out blank. 14 tests, including comma and quote escaping, malformed colours, a pencil with no points, and the blank-line regression.
