Defined in:

Overview

Commits a canonical composition hash to the RM graph with immutable-append versioning: every commit snapshots a fresh graph and appends a Version; a prior head (found by uid) keeps its graph but loses latest_version. Shared by Storable's save hook (GraphPersister, owner: the scaffolded record) and the openEHR REST API's COMPOSITION endpoint (owner: nil, graph-only).
