A noise-reduction change invalidated the scene-linear stage and with it every spatial plane (base, clarity, dehaze, chromaticity), so each tick of an NR drag on the CPU rebuilt all of them. The plan now also carries the linear key without the NR settings; a draft render whose image differs from the cached one only in NR keeps those wide blurs and redoes only log luminance and the fine texture band. Full-quality renders never take them. Draft NR drag, single thread: prepare 18.7 -> 7 ms (render ~135 -> ~125 ms CPU). Sources: own design.
