The tab workspace reports an incorrect selection allowed under lock.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Locked tabs forbid replacement and close commands but permit selection, scrolling and explicit duplication. Lock badges and command predicates are attached to view identity.

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.
