Record exact-SHA scale and extended G samples, same-source blur measurements
and retained negative saved/input results. Keep STEP20C NEXT and production
multi-output unsupported; no production integration.
Preserve immutable probe fixtures, offline regressions and compact artifact
provenance. Fourteen consumed runs / 125 output captures, independent final
audit accepted. Saved timeout/GPU lifetime, whole-H1 return, input after camera
mutation and all-frame damage remain open.
