SHA-256 of the resource content (excluding server-managed meta fields and the hash carrier), stamped by ingress pipelines on every write so re-runs can skip unchanged resources (ADR 0055, as revised). Carried in meta.extension because a meta.tag display is not round-trip-safe on FHIR servers that normalize tag displays (fire-arrow-server issue #713).
