The tab workspace reports an incorrect peer end clamp.

Member previewVariant 4 · 3 implementations · 6 checks per implementation

Case contract

Linked views of one document synchronize only scroll events from the elected source; map proportional content positions into the peer range and suppress echoed tokens.

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.
