Protocol B append (phases 146-149) for the four TODO items: the
search tool line missing the grep's document scope (146), sync-only-
what-changed via a raw-file byte hash checked before extraction and
vision (147), pictorial PDFs showing their rendered pages in the
sources viewer instead of page descriptions (148), and the sync
detail moved to a text box under the button with the button as a
spinner (149). TODO.md cleared (items now live in .agents/phases/
todo/).
