Research-currentness evaluation

This suite evaluates research-backed-engineering with a stale local note and a live-current API contract. The researcher must use dated primary OpenAI sources, the implementation specialist must work from the approved dossier, and the offline auditor must verify source-to-code compliance without silently introducing fresh claims.

The validator does not call an external API or require a credential. It checks stable Responses API request/response semantics and the presence of a dated official-source dossier; the run transcript and worker contracts provide the research evidence.
