Plain v2.x tags are now the active tagging scheme; iso/v1.0.x tags are legacy. Swap priority in resolve_iso_version so the ISO is named bee-debian12-v2.x-amd64.iso instead of v1.0.x-N-gHASH. Also tighten the v* pattern to v[0-9]* to avoid accidentally matching other prefixed tags in both resolve functions. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
