        a request with the same key returns the original outcome verbatim
        instead of creating a duplicate resource. Reusing a key with a different

      description: >
        Request signing with an access key issued to a service account. An

        HMAC-SHA256 over a canonical form of the request, close to AWS SigV4.

        The `basaltic` CLI signs for you.


        Send `Authorization`, `X-Date` (UTC, `YYYYMMDDTHHMMSSZ`) and `X-Nonce`

        (random per request); add `X-Content-Sha256` to bind a body, and

        `X-Amz-Security-Token` when using temporary credentials.


        ```

        Authorization: BASALTIC-HMAC-SHA256
        Credential=<access_key_id>/<date>/<region>/basaltic/basaltic_request,
        SignedHeaders=host;x-date;x-nonce, Signature=<hex>

        ```


        `<region>` is the region code you are calling, or `global` for the
        global

        services. A signature is valid for 5 minutes from `X-Date`, and mutating

        requests are replay-guarded on the nonce.


        **Full signing procedure, including a working implementation:**

        ## Rate limits

        There is no global request budget. A limit applies only where an

        operation documents a `429`, and that operation says what it counts.

        Those responses carry `X-RateLimit-Limit`, `X-RateLimit-Remaining`,

        `X-RateLimit-Reset` and, on a `429`, `Retry-After` — read them rather

        than hard-coding a number. Retrying before `Retry-After` is refused and

        extends the window. Everything else is bounded by quota, not by request

        rate.
