The contract between the editor, the server build and the launcher: the complete set of non-stock
artifacts a release runs with, each with its consumers and the release that introduced it, so a
server build fetches everything from one manifest and never a client-only file. Migrations are
pinned by hash in the core checkout; binaries live under releases/<introducedIn>/, never
rewritten. `manifest-check --previous` refuses a release that drops or rewrites an inherited DBC.
