      description: 'PRIMARY trigger: the nonce travels in the PATH, which survives stripping.


        Mediated chatbot URL-fetchers routinely strip query strings, so a query nonce

        can silently never reach the server (the bug that minted a server nonce the

        agent never sent). A path segment is almost never stripped, so this is the

        documented primary form; it shares all logic with the query fallback.'

      description: 'FALLBACK trigger: the nonce travels in the query string.


        Kept for agents whose fetchers do honor query strings. When the query is

        stripped, ``nonce`` arrives as ``None`` and the server mints one — but the

        response now reports ``nonce_origin: "server_minted"`` and ``yours: False``

        honestly, and points the agent at the path form. A fresh nonce runs the full

        cycle and records its chain-time anchors; an existing nonce returns the same

        cycle without re-running. Fresh triggers are rate-limited per hashed client

        IP; over the limit answers 429 with a Retry-After hint.'
