WalkthroughThe changes remove obsolete TODO comments from Android and Apple gesture handler code. They also clarify the platform-specific behavior of ChangesGesture handler documentation cleanup
Suggested reviewers: Merge Risk: 🔵 Low · up to The PR does not change runtime behavior, but one web documentation note inaccurately groups activation behavior across roles and could mislead future maintenance.

Pull request overview
Removes stale TODO comments across the Android, iOS, and web implementations of RNGH where the behavior is intentional and not unfinished, keeping the codebase’s comments aligned with actual intended behavior.
Changes:
- Web: replaces an “activation on start” TODO with an explanatory note about the
shouldActivateOnStartbehavior on web vs Android. - Android: removes outdated TODOs around
rootHelperinitialization and event coalescing for state-change events. - iOS: removes the matching event coalescing TODO for consistency with Android behavior.

Describe Switch activation separately.
The second sentence is too broad. NativeGestureRole.Switch also activates in newPointerAction() at Line 169, before pointer movement. State that Button uses this flag, while Switch and RNGH text activate on start and other handlers use their normal interaction rules.
Proposed wording
- // role, while other roles intentionally activate on real interaction.
+ // role; Switch and RNGH text activate on start, while other handlers use
+ // their normal interaction rules.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Description
Removes TODO comments that describe deliberate, final behavior as unfinished work. No logic changes.
android/.../react/RNGestureHandlerRootView.kt- drops theresettable lateinitTODO from the 2021 Kotlin conversion;rootHelperis assigned at most once and never reset, so the nullable var is the intended shapesrc/web/handlers/NativeViewGestureHandler.ts- replaces the activation TODO with a note thatshouldActivateOnStartis documented as Android-only and on web is honored internally only for the Button role, other roles activate on real interaction on purposeandroid/.../react/events/RNGestureHandlerStateChangeEvent.kt- drops twocoalescingTODOs; state transitions are discrete and each one must reach JS, so they are intentionally never coalescedapple/RNGestureHandlerEvents.mm- drops the same coalescing TODO fromRNGestureHandlerStateChangefor consistency with AndroidTest plan
