      # The TypeScript side of the CultMesh authority rules. This job is the
      # only one that runs on both Windows and Linux for main, codex/** and
      # pull requests: cultnet-interop.yml is windows-latest and main-only, so
      # until these steps existed the shared verifier's tests never ran on
      # Linux at all, and the browser client's never ran in CI on any OS.
      # packages/cultnet-ts verifies both vector files; cultmesh-browser proves
      # the browser client reads the shared rules rather than its own.

      # The realtime frame codec. Its byte parity rests on two vector files,

      # reference and decoded by this step, and realtime-frame-vectors.ts-written.json
      # written by this codec and decoded by the C# step below. Neither half ran
      # in CI on any OS until these two steps existed, so a codec that agreed
