- Around line 101-126: Update createScene to call
assertUniqueKeyBindings(scene.components, scene.directLink, scene.directLinkKey)
immediately after assertDirectLinkInScenario, before saving the scene, so
creation enforces the same binding validation as patchScene.
- Around line 383-390: Validate that no component ID appears in both
deletedComponentIds and components before deriving effectiveComponents; reject
the request when an overlap exists, then preserve the existing filtering and
merge behavior for valid inputs.
- Around line 375-403: Make the scene update flow containing
assertUniqueKeyBindings atomic through persistence by using an optimistic scene
revision check or a database transaction spanning the scene read, validation,
and write. Ensure concurrent patches cannot both validate against the same stale
scene and commit conflicting bindings, and add an integration test covering
concurrent scene updates.

Make binding validation and persistence atomic.
Two concurrent patches can read the same scene, both pass assertUniqueKeyBindings, and then persist the same key on different components. This defeats the server-side collision guarantee.
Use an optimistic scene revision or a transaction that covers the read, validation, and write sequence. Add a concurrent-patch integration test.

There is a bug where the key hint doesn't show

This happens only when you copy paste components

Possible concern, the hint shows uppercase letters but bindings can only be lowercase letter

When you create these links to a slide and you delete the slides, keybinds dont get unset

erm i can't recreate this? whenever i copy paste a component it removes the key binding (intentional). could u walk me through how to get this?

Can you also check that if there is a button which goes to the same scene if it resets state variable to default values?

Please bring this up in the next meeting but we need to disable the create button after each click because otherwise you can click it 500 bilion times and it creates 500 billion new pages with the same name

a decent amount here relating to direct link has been changes in my pr, since it gets replaced by actions. it works fine for me in terms of logic, one thing is this overlap occuring:
BUT, we can address that after, i want to get this merged first so it doesnt snowball even larger. Just remove the comment slop before you merge pls

Synchronize all open-scene components after scene deletion.
KeyBindingSettings runs only for the selected component while the Actions panel is open. An unselected component can retain a deleted nextScene in useVisualScene. A later edit can submit that stale component and reintroduce the deleted reference. Move this cleanup to scene-level synchronization and process every component. Preserve keyBinding when another action remains.

Move the missing-scene cleanup out of the selected-component-only
KeyBindingSettings effect into scene-level synchronization that processes every
component in the open scene. Clear deleted nextScene references and remove
keyBinding only when no other click action remains; preserve it when another
action is still available.

Issue
Buttons in a scenario could only ever be activated by mouse click. There was no way for an author to navigate with their keyboard apart from the "Direct Link" button which had its limitations. The existing "Direct Link" advance-to-next-scene feature was hardcoded to always respond to Space or the right arrow key with no way to customize it.
Solution
[W]) can be shown next to a bound button, with a configurable position (6 spots around the button), visible both in the authoring canvas and during actual play.assertUniqueKeyBindingsinsceneDao.patchScene) rejects any save that would leave two components, or a component and the direct link, bound to the same key.Risk
Scene.directLinkKeyis a new, additive schema field (defaults tonull); no data migration is needed sincenull/unset still means "respond to Space or Right Arrow," exactly matching every existing scene's current behavior.assertUniqueKeyBindingscheck is a new 400 rejection path, which is a scene patch that would create a key collision now fails at save time instead of silently succeeding. This is intentional (data integrity), but is a new failure mode; worth confirming the frontend surfaces a clear error rather than a generic "something went wrong" toast if it's ever hit in practice.Checklist
