Field-guide appendix
Archive counts
Static counts generated from the canonical registry records.
These figures summarize registry coverage, lifecycle aftermath, exclusive status counts, chain coverage, marketplace scope, and review-quality signals. They are not live market analytics, rankings, uptime monitoring, or price data.
Review-state note: reviewed_staging means a source-reviewed canonical draft, not final public-quality certification. Missing lifecycle or successor data means “not recorded in the registry”, not proof that no event occurred.
