`platform.case`

domain: platform

A CASE — one running instance of a service/solution's workflow. The case is the spine: tasks belong to it, a decision resolves it, and it holds the authoritative status + an append-only history. The execution engine is the single writer of case state, so the history is authoritative, not reconstructed.
