The enforcement story hangs off this type: the lake does not evaluate
this doc type — it is the engine's placeholder for the lake's
forthcoming guard primitive (the lake reserves system.*). Until that
primitive ships, deployed guards deny OPTIMISTICALLY engine-side only, on
every project plan, and the lake ACL is the only hard gate. At cutover the
temp. prefix drops here, in exactly one place, and deployed guards become
lake-enforced (a breaking type change for already-persisted guard docs).
