Ready for dev in Figma Dev Mode creates no immutable snapshot after designer edits

Ready for dev in Figma Dev Mode creates no immutable snapshot after designer edits

Goal: Determine whether design-to-code consumers can treat a Ready for dev designation as a stable version boundary, or whether they must implement separate change detection for frames edited after the flag is set.

Documented behavior indicates that marking a frame, component, or layer Ready for dev signals completion but does not lock, freeze, or prevent further edits. Dev Mode code panels reflect the current canvas state at inspection time rather than a snapshot tied to the ready flag, and there is no automatic notification or version diff when a marked item is changed afterward. The ready status is stored per file and per item, but it is not described as an immutable release artifact in the Figma REST API.

Uncertainty remains about whether behavior differs across Figma desktop, web, and Dev Mode access roles, and whether API consumers can rely on the ready flag without additional change-tracking.

Specific questions:

• Can a consumer detect that a previously Ready for dev frame has been edited after marking using only the Figma REST API?
• Does Dev Mode expose any version or timestamp boundary associated with the ready flag that distinguishes inspected code from later canvas changes?
• Should teams treat Ready for dev as a non-locking signal and require an external handoff freeze process instead?
