Code systems served
One table of every code system FerroTERM serves: the canonical URI each is
served under, the versions and editions handled, how you bring its content,
and its licence position. This page is the single source; the README and the
landing page carry the same names, and a check in CI fails when a row here is
missing from either. The design notes per system (identity rules, filters,
properties, implicit value sets, with their citations) are in
docs/terminologies.md in the repository.

Every system reaches the operations through one provider seam, so nothing in an operation is a special case for one system. The repository ships no code system content, licensed or open: you bring the release you are licensed for, and the build tool turns it into an index. The loading page shows each build.
