Logically invalidate HANDLE immediately. Native teardown may be deferred until submitted work which captured HANDLE has completed.

Return where OVERLAY draws: :SCENE, :WORLD-PANEL, :VIEWMODEL, :HUD, or :NONE. Scene overlays inhabit world depth; viewmodels are first-person geometry above the world but below held items and the crosshair. World panels retain world projection and depth while drawing analytic application graphics at native…

Return OVERLAY's positive camera-space depth for world-panel ordering. Native-density panels are alpha-composited far to near before their completed depth layer meets the game scene. Non-spatial panel implementations may keep the stable attachment order by returning the default zero depth.

One authored solid and its vocabulary-closed material-placement field. The solid remains LUFT's topological truth. The sparse authored field stores only dense vocabulary offsets; semantic material objects remain at the scene boundary rather than being allocated per cell.

The sole owner of a session's frame attachments, layouts, pipelines, and per-drawable GPU state. The session coordinates this owner with simulation, streaming, overlays, and presentation; it does not duplicate its inventory.

Test whether two compatible scalars are equal.

Test whether one compatible scalar is greater than another.

Adopt a pre-renderer SESSION's discarded slot values into one owner. RETIRED-VALUES is the property list supplied by UPDATE-INSTANCE-FOR-REDEFINED-CLASS. Unbound old slots remain unbound in the new renderer; owned resource and frame-state collections retain identity.

Release every resource owned by COMPONENT. Component release is an owner boundary: callers name the component once, rather than reproducing its private resource inventory.

All named failures from a completed release sequence.
