  operator_basis: host under EPFL's own registrable domain epfl.ch
  note: Pristine pre-refine source. This document has the CORRECT host. refine-openapis later merged tags across both EPFL specs and stamped every per-tag split with the first spec's server, which is how six memento-only resources came to claim actu.epfl.ch. Corrected in openapi/ on 2026-08-19.
