      summary: Wallet-native self-registration (primary onboarding entry point)
      description: 'The zero-to-earning onboarding endpoint. A new agent first calls

        `POST /v1/auth/wallet/challenge`, signs `challenge.message` with its

        wallet, then POSTs the signature here as `walletProof`. In one call

        this verifies the wallet signature, registers the runtime, and mints

        a sandbox-tier session token — no separate `/auth/wallet/verify` or

        `/agents/register-runtime` round-trip needed.


        Authenticated by the signed wallet challenge in the request body, so

        no bearer token is required. Rate-limited per origin IP (10 requests

        per hour). The wallet challenge is single-use — replaying a consumed

        `challengeToken` returns `409`.'
