# META-6 — The entity tag carries the body variant, not just the schema version

*RT-META (Part II) · level: core · profiles: runtime, editor-client · added in 1.0*

A missing variant in the tag was a live cross-repo cache bug: a client holding the plain body asked for the annotated one, was told it was unchanged, and went on serving a document with every title and description missing.

## The rule

> **Normative.** This is the rule.
>
> 1. The entity tag for a workflow schema is the quoted schema version for the plain document, and the quoted schema version plus a variant marker for the annotated one.
>
> 2. Any request argument that changes the body must join the tag the same way: two documents that differ must never share a tag, whatever else varies on them.
