When an ACTION_UP event carries movement after the last MOVE, DragGesture.onEnded reports a stale location and translation. Forward the final pointer change from both regular and simultaneous detectors, then include its delta before completing the gesture.

Accepted cancellations retain their last known value; gestures that never pass touch slop do not produce an end callback. The existing SkipFuseUI callbacks remain compatible.

Validation

• CI passed for 54e4b10, including Swift/Robolectric, iOS, and Android emulator tests.
• Nine regression tests cover release-only movement, touch slop, global coordinates, repeated drags, and cancellation on Android API 34 ARM64 and Robolectric.
• Reverting the gesture fix makes all five release-position cases fail while the four cancellation/unaccepted cases still pass. Restoring it passes all nine.

The broader local run combined the independent drag and path changes on upstream base 5504558. Host swift test --skip XCSkipTests completed 135 tests with 63 platform skips and no failures. The full Android run completed 228 tests: 211 passed, 14 skipped, and 3 failed. The three font-metric failures (testTextSizeHeadline, testTextSizeCaption, and testTextSizeBody) also reproduce on unchanged upstream source with its original dependencies: actual/expected values 18/19, 12/13, and 18/19 respectively. The focused regressions pass on Android and Robolectric.

Checklist

• Signed the Contributor Agreement; the current CLA check passes.
• Tested locally with swift test and separate Android/Gradle runs.
• Tested on iOS through CI.
• Tested on an Android emulator.
• Checked Skip Fuse UI compatibility; no corresponding API change is needed.
• Added a Showcase example (optional).
• AI assistance: Codex assisted with implementation, regression tests, review, and automated validation.

Additional reproduction and verification details for 54e4b10:

The regression injects a down at (20, 30), a move to (100, 50), then changes the pointer to (180, 90) immediately before release, without sending another MOVE. The assertions require the end value to include the final 80-by-40-pixel delta, converted to points, while preserving the start location. Repeating the gesture also checks that accumulated state is reset.

From the generated Gradle root, the focused Android suite is:

gradle :SkipUI:connectedDebugAndroidTest \
  '-Pandroid.testInstrumentationRunnerArguments.class=skip.ui.DragReleaseTests'

The saved API 34 ARM64 comparison has five release-position failures with the original implementation and all nine tests passing after restoration. The four cancellation/unaccepted cases pass in both runs.

The current PR CI run passed, including iOS and Android emulator jobs. The CLA check also passes. The broader local font-metric failures are documented in the description and reproduce without this change.
