- 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).
