Dirty transition gate.

Member previewVariant 4 · 3 implementations · 60 checks per implementation

Case contract

The blocker asks only for dirty cross-location transitions without a one-shot bypass. Confirmation follows the captured pending destination, cancellation keeps current location and edits, and push versus replace is independent. Operation dirty-transition-gate has the six explicit input/output oracles below.

Why this case matters

An offline client lifecycle model that isolates a state-management defect without DOM rendering or network services.
