+**Model status:** Pilot model — built and actively improved through iterative research phases.

+> We also maintain an internal, evolving suite of curated hard cases (Pidgin, dialect, regulatory
+> register, clinical shorthand, minimal pairs) used to diagnose and target specific model weaknesses
+> during development. It's a diagnostic tool, not a benchmark — we don't publish a fixed pass-rate from
+> it here, since the suite and the model are both still changing, and a fixed percentage risks reading as
+> a settled result rather than a snapshot of an active development target.
