- Raise eval_softmax_temp lower bound from 0.01 to 0.1 (log scale) to prevent near-greedy collapse in hyperopt walk-forward eval. Temps below 0.05 produced degenerate 1-trade trials even with softmax sampling. - Mount MinIO CA cert in CI compile pods and append to system trust store so sccache S3 backend can verify MinIO's self-signed TLS certificate. - Add openssh-client to ci-builder-cpu Dockerfile (missing, broke git clone over SSH). - Bump MinIO memory limits from 512Mi to 2Gi (OOMKilled under load).
