Schema.org quarterly changelog audit for multi-location operators

Schema.org publishes quarterly releases (v28.0 March 2026, v27.0 November 2025, v26.0 August 2025). Schema App, Yoast SEO Schema, RankMath, Schema Pro, WPSchema, Merkle Schema Markup Generator, JSON-LD Generator by Hall Analysis, Schema.dev ship per-platform schema-generator primitives. The schema-org-quarterly-audit skill on the integration-drift-monitor agent — running per-portfolio per-page-type per-property per-enumeration per-version-diff detection + per-JSON-LD-markup-audit + per-auto-PR-generation for affected page generators + per-deprecation-sunset-countdown + per-portfolio audit-trail at multi-location-schema-operator scale — is operator-side architecture above the per-platform primitive.
