+"""Regression: params_b must not crash the ranking pass on a malformed count.
+
+`parameter_count` is matched with `^([\\d.]+)\\s*([BKMGT]?)$`. The `[\\d.]+`
+class happily matches a multi-dot value like "1.5.3B", but `float("1.5.3")`
+raises ValueError. params_b is called for every model in analyze_model/
+rank_models, so one bad catalog row aborted the entire ranking request. A
+malformed count is now treated as unknown size (0.0) instead of raising.
