Inspector Rail

Installable list-detail expansion pattern for a preview card opening into a right-side supporting pane.

Inspector Rail

This is the corrected meaning of inspector rail in KnearMe: a compact preview opens richer supporting detail in a right-side pane. Debug-only runtime inspectors are a subtype, not the definition.

What it is for

Support list-detail expansion without overloading the inline card.

Use when

The user can choose from several previews and needs expanded supporting detail for the selected item.

Do not use when

The right-side content is the primary task itself rather than supporting detail.
