The R-4 feedback identity: the target this frame draws into, or null.
The frame's colour-attachment format (#frameFormat).
The frame's depth-attachment format, or null (WP-R1.6).
Whether the frame's depth attachment carries §67's stencil planes.
§9 render time in seconds (WebgpuRenderer.renderTime).
§84's counters, or null to count nothing.
The pass's mirrored stencil reference; draw returns the new value.
The current view's projection × view (§47).
The per-draw frame state a node draw reads — a pooled, mutable record the renderer rewrites per draw (plan D7: the frame loop allocates nothing); the store must read it during the call and never retain it.
