Block steering: run-averaged block activity is architecture-determined
(varies in the 4th decimal run-to-run), so no scoring scheme - pole EMAs
or reward correlation - could extract a rating signal from it. The idea
needs within-run per-step measurement to have a chance; that is a
research project, not a feature. Removed: module, sampler wiring, the
two trailing widgets (positional reference mapping unaffected), the
Refiner pairing hook, editor knobs, tests. Stale block_snapshot/
block_profile sidecars are inert and covered by the existing
delete_refinement_key sweep.
FunPackNVFP4ModelLoader: the FP4 GEMM path was real (3.35x at 16k
tokens) but end-to-end the user's runs are dominated by everything the
loader cannot touch (attention, prep, encode - the sampler node is
~23s of a ~60s run) while dynamic input quantization added a fixed
per-layer-call toll. Net observed: overhead. Users are better served
by dedicated NVFP4 loaders. Removed: module, registration, tests.
Kept (independently useful): the chain sampler's phase timing report +
quantized-layer census, the nested-AV x0 snapshot fix, and the sm_120
masked-attention work.
