/**
|
|
* AI regeneration lock predicate — the reverse direction of #564's
|
|
* auto-exit. `isCurrentSceneEditable` blocks ENTERING edit mode on a
|
|
* generating scene; this predicate is the check regenerate-this-scene
|
|
* call sites perform before STARTING generation, so a scene that is
|
|
* currently being edited cannot have its content silently replaced.
|
|
*
|
|
* Pure function — caller pulls `mode` + `currentSceneId` from the stage
|
|
* store and provides the candidate sceneId. Pessimistic semantics
|
|
* (refuse, do not queue) match the v0 design; callers surface the
|
|
* refusal however makes sense locally (toast, retry-later button, etc.)
|
|
*
|
|
* Wiring (slide-surface PR / future regen entry points):
|
|
* - `useSceneGenerator.retrySingleOutline` calls this before kicking
|
|
* off content generation; if locked, returns early.
|
|
* - Any future "regenerate a successful scene" feature does the same.
|
|
* - Current `retrySingleOutline` only operates on failed outlines and
|
|
* so cannot structurally hit this guard, but the pattern is in
|
|
* place for the moment a successful-scene regen ships.
