+control is historical ordinary print, not contemporary fullpage evidence.
+No production-readiness or SOTA claim; no existing model was overwritten.

+This is separate from Qwen/EZH historical experiments. This registry entry
+contains only metadata; all runnable code and weights are preserved in the
+dedicated snapshot, with raw inputs/outputs, limitations and checksum proof.
