Rank-7 toy Rota Basis conjecture and de-randomization

Let $M$ be a rank-$7$ binary matroid instance from the circuit-rich pool template described in the source, including trap instances and conjugation by $\operatorname{GL}(7,2)$. Rank-7 toy Rota Basis conjecture. The evolved policy succeeds with probability $1$ over its internal randomness, and there is a deterministic de-randomization, obtained by removing the noise and using deterministic tie-breaking, that succeeds on the same class. This is an experiment-specific computational claim rather than a theorem about all rank-$7$ matroids, and the supplied text does not establish it mathematically.
