The tab workspace reports an incorrect completion correlation.

Member previewVariant 2 · 3 implementations · 6 checks per implementation

Case contract

Closing a dirty tab waits for its save generation, accepts only matching successful completion, retains the tab on error/cancel and clears dirty only at the saved revision.

Why this case matters

Offline tab/panel workspace behavior; no browser or desktop framework is emulated.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.
