Verifiers v0.1.15.dev6 Release Notes

Date: 05/14/2026

Highlights since v0.1.15.dev5

• Routed-experts token metadata is handled as an opaque payload. OpenAI-compatible chat and text-completions clients now preserve routed-experts data without expanding it through user-facing message types, and token parsing truncates that sidecar alongside prompt/completion tokens when a rollout is clipped to max_seq_len.
• v1 EnvConfig typing is stricter. The v1 loader envelope, config docs, generated environment templates, examples, and tests now keep environment-level configuration narrow while routing taskset- and harness-owned fields through their concrete config classes.
