Transparent rule reminderRecordsCohort share
Contains registration-narrative wording45.3%

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

16 of this cohort’s 75 records link through existing company-ID mappings to 2026 lists from all jurisdictions (21.3%). This intersection measures list linkage, not successful recognition or company growth.
