# Manual input validation: standalone and IntelliJ

Status: **passed; the stage-2 physical drag/resize validation gate is closed for the tested baseline**. Konrad performed the tests with physical mouse input and reported each result in the development conversation on 2026-11-12. This record complements the automated projection checks; it does not turn synthetic events into hardware evidence.

## Artifact and environment

- Source-preserving projection: `dfa2dd1`; corner-resize correction: `b9d59e162f0df20057d50b5d0ec4ef54cc92d73e`, on NeitzelFXDesigner main.
- macOS arm64; host OpenJDK 25.0.5.0.3, JavaFX 26+27 and Scene Builder Kit 26; IntelliJ IU 263.7307.200 with bundled embedding disabled and JavaFX/FXML language support retained.
- Classpath fixture application on Java 21 / JavaFX 21.0.7, using the recorded corrected NeitzelLib development artifact. Module-path applications additionally pass the automated shared-host checks; no separate human module-path pass is claimed.
- Disposable Person.fxml with an AnchorPane and two independently editable Card instances. Standalone retest labels: **Corner resize retest** and **Second**. IntelliJ labels: **Drag me** and **Second**.

## Human results

| Check | Standalone | IntelliJ |
| --- | --- | --- |
| Drag first Component; release retains position and responsive canvas | Passed | Passed |
| Undo/Redo drag with one action each; other Component unchanged | Passed | Passed |
| Drag second Component independently; Undo/Redo preserves first | Passed | Passed |
| Corner resize first Component; width and height persist together | Passed after correction | Passed |
| Corner resize second Component; independent Undo/Redo | Passed after correction | Passed |
| Right edge changes only width; bottom edge changes only height | Passed | Passed |
| Edge resize persists on release; one-action Undo/Redo | Passed | Passed |
| Save and Source/Design switch preserve both declarations and layout | Passed | Passed |
| Saved prefWidth/prefHeight survive reopening; selection/resizing still works | Passed | Passed |
| IntelliJ Edit menu and keyboard shortcuts undo/redo the drag | Not applicable | Passed |

The original standalone corner gesture persisted only width. Kit emits separate synchronous jobs for each changed dimension; an asynchronous host transaction started after the first notification dropped the second. The correction collects the completed FX event turn into one source-preserving transaction. Both Components were explicitly retested, including save/reopen. See [projection implementation](source-preserving-projection.md#corner-resize-correction-and-manual-review).

## Gate boundary and remaining evidence

This closes the pending human OS drag/drop and resize gate for stage 2 on this fixture/platform. No additional repetition of the same checklist is required before stage 3. Keep the shared automated regression in both hosts and repeat the affected manual checks when input/projection/host changes warrant it.

It does not qualify every control/container, trackpad/horizontal scrolling, IME, display scaling, other operating systems or IDE versions, packaged releases, or the forthcoming nested/repeated/Table runtime behavior. VoiceOver remains outside the agreed scope. One earlier automated IntelliJ run failed a later save-preservation assertion; the next complete run passed. The assertion now records expected/actual text if it recurs; these human save/reopen passes do not establish its cause.
