Existing fracture literature can plausibly supply independent measurements, but a named open dataset with broad matched coverage is not established here. Compilation can resolve the effect in restricted regimes, while the universal forbidden-speed wording is harder to establish." . . . "Proposed test with existing data: Compile time-resolved crack-tip position in loaded single-crystal silicon, estimate velocity immediately after initiation, and test whether observations occupy zero or speeds at and above about 2 km/s with a gap below the threshold. Reproducible sub-threshold propagation would refute the forbidden-speed claim." . "GPT-5.6 Sol on buehler-2007-silicon-crack-01: partially-resolvable, resolvability 0.71" . .
