command-r:35b vs Claude Sonnet 5

Both models answered the same one-shot tasks under identical rules — no retries, answers published unedited. Two separate axes, never blended: does the code actually run, and how do blind-scored text answers hold up against a written gold answer. Frontier references sit outside the blind field and are deliberately unscored on text.

Model	Runnable sims	Blind text avg	Failure modes
command-r:35b	25% (24/95)	6.87 (30 scored)	ERR 33 · STAT 10 · BLANK 8 · HANG 3 · DNF 17
