-- The list of predefined keys (novox/hq ADR 0348 clause 7, design 57 package K2, issue 661).
--
-- Mesh config and node config hold values only for the keys in the catalogue's `predefined.json`. A build of
-- the catalogue reads the file at the commit it builds and carries it; the controller keeps the newest trunk
-- build's, which every manifest it reads again is judged against, and which mesh-config publishes from here
-- (design 57 package K3). One list for the mesh: one row.
--
-- **The newest trunk build wins**, by the generation of the commit built — how many commits it stands on, which
-- of two commits on one trunk is larger for the later — so a list heard late from an older build never replaces
-- a newer one. Not a config value: a key, its type, description, validation and whether it is trusted, all of it
-- public in the catalogue's repository.
