 Still in the target and not yet claimed:
 
+- **The input restructure** -- `src/default/sense.rs` becomes `src/rsc/sense.rs`
+  (308 lines to 2313), plus `core/src/event/controller.rs`, `desktop/input.rs`,
+  `android/input.rs` and `sense_tests.rs`: pointer capture, drag slop and axis,
+  platform cancellation, mask-aware hit testing, event timestamps. It replaces

+  consumption defect #12 removes** -- extracting it as-is brings the bug back,
+  so `tests/pointer_routing.rs` is the acceptance criterion for that slice.
 - Widget draw size and measurement cleanup (source commit `6671194`).
 - Retained span, scrolling and layout placement.
 - Retained paints, selection, overlays and shared UI runtime state.
