event_date_initiated coverage
June 01, 1997–June 30, 2026
Enforcement coverage uses report dates; product initiation dates can precede those bounds. Device-enrichment coverage uses FDA event_date_initiated.
Product dates, classifications, firms, and source wording remain attached to their individual rows.

These labels are deterministic app interpretations, not FDA categories.
Official device-enrichment evidence · Unknown
An exact joined enrichment record exists, but none supplies supported root-cause wording. This is not an FDA finding of an unknown cause.
