# Application UI ownership
|
|
|
|
`src/ui/applicationShell.js` constructs controls, connects their explicit inputs
|
|
and coordinates shutdown. `shellFacade.js` preserves the methods used by layers,
|
|
scene playback and voice. It delegates; new behavior belongs with its owner.
|
|
|
|
| Owner | Responsibility |
|
|
| --- | --- |
|
|
| `navigationController.js` | Navigation generation, tracking release and camera authority |
|
|
| `locationNavigation.js` | Destination lookup/selection, orbit, world jumps and globe-reset completion |
|
|
| `cockpitCoordinator.js` | Cockpit entry/rollback, readouts and the single Display portal |
|
|
| `visualSettings.js` | Effects, detection overrides, visual restoration and render-loop lifetime |
|
|
| `panelChrome.js` | Disclosure, docking, layout and Cockpit panel restoration |
|
|
| `aircraftDisplay.js` | Shared commercial/military 3D display preferences and controls |
|
|
| `layerBindings.js` | Data-manager attachment, selected-tracker adoption and camera-entry listeners |
|
|
| `displayBindings.js` | Keyboard/display subscriptions and frame-rate monitor lifetime |
|
|
| `shareRestoration.js` | Initial share/layer restoration and cancellation |
|
|
| `shellFeedback.js` | Loading feedback, notices and toast lifetime |
|
|
|
|
Owners receive named services, elements, operations and readers. They do not
|
|
receive the application shell itself. Readers resolve a replaceable collaborator
|
|
at use time; operations cross an ownership boundary without copying its state.
|
|
The facade exposes existing properties as delegates rather than duplicate state.
|
|
|
|
Shutdown has two phases. First revoke input, deferred navigation, camera-entry
|
|
listeners, lookups, timers and rendering work. Then await Context restoration,
|
|
release sensor overrides while the manager is still attached, detach layer
|
|
services and destroy scene resources. Late callbacks cannot acquire the camera.
|
|
Manager replacement also releases subscriptions and the previous Directions
|
|
module even if the replacement does not provide a Directions layer.
|
|
|
|
Source-contract tests follow both sides of delegated wiring. Lifecycle tests
|
|
exercise pending reset cancellation, stale camera callbacks, replacement and
|
|
idempotent teardown. Browser acceptance covers the composed application, including
|
|
share restoration, scene commands, navigation, Cockpit, display and voice.
