~anthropic/claude-sonnet-latest → B (6:4)

Side B lays down the actual foundational architecture (ItemId path canonicalization/breadcrumbs, GlobalTree replacing the flat GroupMap, journal worker, parser rewrite) that Side A's commit builds directly on top of (rank_list/tree signature, entity_panel, reddit render module). Side A is a nice incremental feature (reddit post thumbnails/images) but is smaller in scope and depends on B's tree/ItemId infrastructure to even function; B's changes are more foundational and broadly enabling despite being messier/larger.
