// A one-entity patch costs 73 ms in this block, and the

// produced last frame. Skip it when no changed entity
// feeds them and none did before.

// Safe because adding an entity does not disturb any
// other entity's draw depth: `inserted_draw_depth_label`
// allocates into the reserved label gap rather than
// renumbering, so instances already uploaded stay right.
// Retain analytical uploads when a patch changes neither
// their contributors nor their baked draw depths.
