+If you add a test that talks to the network, mark it ``slow`` — otherwise you
+silently break offline builds for every downstream packager.

 4. The activation function obtains a new JWT token and updates it in the site check record
 5. On the next site check (either through retry or a new Maigret run), the valid token is used and the check succeeds
 
+Step 5 works across runs because minted tokens are written to a per-user cache rather than back into the site database — see :ref:`activation-token-cache`.

 Examples of activation mechanism implementation are available in `activation.py <https://github.com/soxoj/maigret/blob/main/maigret/activation.py>`_ file.
