Gestures
- Cancel a captured gesture on lostpointercapture, on a new primary
pointer-down, and when its component unmounts, so operations are
never left stuck mid-transition. Bindings gain onLostpointercapture.
- Warn (console.warn) when navigate() fails or the scene rejects an
operation; stay quiet when two recognizers race for one origin.
- OriginGesture and OriginGestureSurface props are reactive. Changes
apply from the next pointer-down; recognizers are kept per list
position so re-renders never interrupt a drag.
- Remove the legacy direction/edge/threshold/action gesture form
(OriginGestureOptions, legacy OriginGesture props, MaybeOriginAction).
Scene
- Honour choreography commitVelocity (default 0.3, as before).
- Scene errors are OriginSceneError with a stable code.
- update() during settling now really catches an operation: the spring
stops, and only the latest finish() decides the outcome.
- Fix graph corruption found by the new property tests, all present on
main: replacements escaping a cancelled push, edges left dangling when
their current target differs from the original one, revealed targets
keeping operations after their back is cancelled, history pointing at
removed entries after replace, visual cycles from back through an
undecided replace, exposed nodes reactivated as active, and a cancel
cascade that could empty the whole scene.
Tests
- Add property tests checking structural invariants after every step of
random operation sequences and pointer streams (PROPERTY_SEEDS).
- Add recognizer tests for stuck gestures, warnings, reactive props,
and commitVelocity. Drop the main-comparison suites; keep benchmarks.
Also fix the origins demo's two pre-existing type errors.

Rewrite the core-v2 internals without changing the public API or runtime
behavior. The four large files (types, scene, motion, gesture) become
layered modules with one responsibility each:
- shared/: geometry and environment helpers
- view/: originView recipes
- choreography/: effect types, presets, and composeEffects compositing
- actions/: forward/back/replace/above/under via one overload resolver
- scene/: SceneGraph storage, transitions (history rules), compositor
(styles and interactivity), spring (pure stepper + rAF driver), and
createOriginScene, which only wires them and owns async timing
- composables/: useOrigin and the node-scope injection key
- gesture/: builder, definition->policy normalization, start admission,
DirectionalTracker, and a GestureRecognizer session state machine
replacing fifteen loose closure variables
- components/: renderers and gesture hosts, plus their prop types
Verification (packages/core-v2/verify): differential fuzzing drives
main and this branch with identical random operation sequences and
pointer streams and requires identical scene state, styles, contexts,
callbacks, and promise results at every step. It caught every planted
mutation that applied. Benchmarks are at parity.
Also fix a pre-existing test that called the defineProps macro inside a
runtime defineComponent, and correct API.md's description of the flick
commit threshold to match the runtime.
