Taxonomy changelog
How the content model evolves
Every change ContentRX has published to the content model: standards added, retired, or revised; moments added or retired; approved refinements from the triage log. Each entry carries a date, a reason, and — where applicable — migration guidance for historical evaluations.
Generated 2026-04-25 from standards_library.json and taxonomy_refinement_log.md. The CI guard in scripts/check_taxonomy_changelog.py blocks PRs that change the taxonomy without appending a version_history entry or approving a refinement.
