A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.

Intersection with 2026 local lists

50 of this cohort’s 284 records link through existing company-ID mappings to 2026 lists from all jurisdictions (17.6%). This intersection measures list linkage, not successful recognition or company growth.
