AlertDialog

A modal decision with a primary message, safe cancel target and explicit action intent.

Root fixes alert semantics. Mask owns modality; Content traps focus, blocks outside dismissal and starts at Cancel when available. Action emits action before requesting close. Application code owns the effect; no destructive operation is performed by the prototype. Escape and Cancel request dismissal.

Root supports controlled open or uncontrolled defaultOpen. Disabled commands do not activate. Supplying open leaves the committed value with the owner; listen to openChange and provide the next value.

Parts: Root, Trigger, Content, Title, Description, Cancel, Action, Mask.

Draft source implementation. Full native/GPUI, compiler, packed-consumer, visual and independent acceptance remain pending; this page does not claim Finf completion.
