Protocol risk gate. Returns `doctrine_action` (BLOCK | ALLOW | ESCALATE), `risk_level`, `risk_score`, and per-domain `risk_domains`. If doctrine_action === BLOCK, halt the action and return `reason_codes` and `recommended_next` to the user. Recheck after `valid_until`. Call this when continuity-mode returns mode !== NORMAL or recommended_posture is require_review or pause.

# 1) An unpaid request returns HTTP 402 with the exact payment terms:
curl -i -X POST "https://selun.sagitta.systems/agent/x402/sce/risk-evaluate" \
-H 'content-type: application/json' \
-d '{"addresses": ["0x4d5F47FA6A74757f35C14fD3a6Ef8E3C9BC514E8"], "chain_id": 8453, "decisionId": "sce-risk-001", "protocol_name": "Aave", "requested_action": "deposit"}'
# 2) Paying + retrying requires an x402 client that can sign the USDC
# authorization (curl alone cannot). See the JS / Python tabs below.
