}

A violation of the format-run invariants, reported instead of asserted.

The invariants used to be guarded only by debug_assert!, which is compiled out of release builds — so a contract violation silently produced a malformed run list in a shipped binary, and (with autosave) that corruption became the file’s new truth within seconds. Anything on the replace path returns this instead, so the use case can refuse the edit and say why rather than quietly mangle a writer’s formatting.
