- Merge the small modules into 12 files: shared, choreography,
navigation, scene/{types,graph,scene}, gesture/{definition,recognizer}.
- SceneGraph now owns the begin/update/commit/cancel history rules as
methods, with the step helpers as private methods.
- createOriginScene returns a markRaw'd Scene class; operation handles
are an OperationHandle class instead of inline object literals.
- GestureRecognizer gains static create()/policyFor() factories, absorbing
the separate policy module.
- Pure helpers used by classes (matchesStart, pointOf, stepSpring,
composeNodeStyle, nodeEffectLayers, shouldCommit, ...) are exported
consts so they can be tested directly.
- Add haptics tests showing where navigator.vibrate can be triggered.
Public exports, types, and behavior are unchanged; the differential
suites against main still pass.

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.
