Per the full-refactor plan §9 (input-independent half of P0): - engine: canonical EditorStroke (lossless InkStroke round-trip) + stroke_geometry (single getStroke outline) + revision-gated StrokeStore - render: static/live ink painters + ink_picture_cache (revision-keyed) + annotation_layer (RepaintBoundary) - persistence: DB v6 (ink, notebook_pages) + editor_repository diff-write (UPSERT changed / DELETE removed in one txn; id-set after commit) + save_scheduler - pdf_service export now FILLS the getStroke outline (R7 hairline fix) Not yet wired into the live editor (input relocation pending pen-pressure diagnostic). 28 new tests pass.
