Option I: add per-viewport Arc wire cache so paper-space viewport rendering no longer re-tessellates model content every frame. Option J: hit_test_wires() returns Arc<Vec<WireModel>> — O(1) pointer copy in model space instead of a full Vec clone on every mouse move during commands. paper_canvas_hatches/wipeouts() now route through the epoch caches added in F. Option K: add world_snap_r + wire_in_range() pre-check to Snapper::snap(). All Endpoint/Midpoint/Nearest/Perpendicular/Intersection loops skip wires whose chord sphere is outside the snap circle using O(1) scalar comparisons, eliminating O(entities × vertices) matrix multiply cost when zoomed in.
