Case contract

An opener path lists ancestor tab IDs from root to direct opener. Related tabs are inserted after the opener subtree in strip order; closing an opener reparents descendants by removing that identity from their paths.

Why this case matters

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