v0.13.0

Minor Changes

• #209 8ec051f Thanks @s-adamantine! - Add app.certified.graph.follow lexicon — a social-graph follow record schema-compatible with app.bsky.graph.follow (same tid key, same subject / createdAt / optional via strongRef fields). Exports new GRAPH_FOLLOW_NSID, GRAPH_FOLLOW_LEXICON_JSON, GRAPH_FOLLOW_LEXICON_DOC, and AppCertifiedGraphFollow type namespace.

Patch Changes

• #213 80e5b42 Thanks @s-adamantine! - Clarify that knownValues is an open vocabulary, not a closed enum. Adds a "Schema Conventions" section to README.md explaining that custom string values are permitted on any knownValues field (and contrasting with enum, which is closed and validator-enforced). Updates inline descriptions on app.certified.location#locationType, org.hypercerts.workscope.tag#category, and org.hypercerts.workscope.tag#status to explicitly note that values beyond the listed set are permitted — bringing them in line with the existing wording on org.hypercerts.collection#type, org.hypercerts.context.attachment#contentType, and app.certified.badge.definition#badgeType. The locationType description now also explicitly calls out that polygons / multipolygons / featurecollections use the catch-all geojson entry rather than a typed variant. Fixes a misleading line in STRING_CONSTRAINTS.md that conflated knownValues with enum. Documentation-only — no schema or type changes.
