V154: OpenGraph templates + hierarchical assignments (phoenix_kit_og plugin).

phoenix_kit_og_templates

Reusable OG canvas designs. canvas is JSONB so the structure can grow new element types without a schema change. preview_image_uuid is an optional pointer to a rendered cached preview.

phoenix_kit_og_assignments

Binds a template to a scope inside a consumer module's hierarchy. The (module_key, scope_type, scope_uuid) triple is unique — enforced via a partial-index pair because PostgreSQL treats NULL as distinct:

  • one row per (module, scope_type) when scope_uuid IS NULL (the module-wide default tier)
  • one row per (module, scope_type, scope_uuid) when not null

template_uuid cascades on delete: removing a template wipes every assignment that pointed at it.

All operations are idempotent.

Rolls V154 back by dropping the two OG tables.

Lossy rollback: all templates and assignments are lost. Back up before rolling back in production.
