How to read a coverage state

Verified
A scoped authority supports a specific usage claim. The published guides above cite their own sources. The frozen dataset ledger retains its original evidence states and does not imply native or specialist approval.
Dataset-derived
Direct CLDR exemplar evidence exists. Its locale, exemplar type and draft status are preserved.
Registry-only/unknown
An IANA record exists, but direct exemplar evidence has not established the orthography.
Historic/specialist
A usage classification requiring its own source and scope. It cannot be inferred merely from an encoded character.
