# Changelog
# ============================================================================
# v1.0-draft.0.2 (2026-08-20) — Per-term maturity. Every term now carries
#   vs:term_status (W3C SemWeb Vocabulary Status, originating in FOAF):
#   "unstable" for draft terms, "archaic" for terms already marked
#   owl:deprecated. The convention is per-TERM by design, so a vocabulary
#   can promote individual terms in place without a namespace change;
#   Cascade previously stated maturity once per vocabulary, in prose no
#   machine could read. No term definition changed.
