Your code, @stveit. I looked for solutions and found this:

Finishing this is blocked because:

There's problems with the direct dependency pydantic on python 3.14. pydantic needs rpds which is a rust crate:

  × Preparing metadata (pyproject.toml) did not run successfully.
  │ exit code: 1
  ╰─> [10 lines of output]
      error: failed to parse lock file at: /tmp/pip-install-nl5ky0_r/rpds-py_0d5a219ec1dd4f848c74cefed920a494/Cargo.lock
      
      Caused by:
        lock file version `4` was found, but this version of Cargo does not understand this lock file, perhaps Cargo needs to be updated?
      💥 maturin failed
        Caused by: Cargo metadata failed. Does your crate compile with `cargo build`?
        Caused by: `cargo metadata` exited with an error:
      Error running maturin: Command '['maturin', 'pep517', 'write-dist-info', '--metadata-directory', '/tmp/pip-modern-metadata-j0t4zoi_', '--interpreter', 'CENSORED/Argus/.tox/py314-django52/bin/python']' returned non-zero exit status 1.
      Checking for Rust toolchain....
      Running `maturin pep517 write-dist-info --metadata-directory /tmp/pip-modern-metadata-j0t4zoi_ --interpreter CENSORED/Argus/.tox/py314-django52/bin/python`
      [end of output]

It seems only argus depends on pydantic so worst case we could try switching to [cattrs](https://catt.rs/).
