Code sample: Shell / cURL 
curl --request POST \
  --url https://auth.example.com/api/v1/login/interactions/example/submit \
  --header 'Content-Type: application/json' \
  --data '{ "step_id": "example", "node_id": "example", "selected_handle": "example", "contract_hash": "example", "signature": "example", "input": { "additionalProperty": "example" } }'

Advances the active runtime Flow step after verifying CSRF, interaction state, expiry, contract hash, HMAC signature, and current step identity. Step input is interpreted by the active runtime component; consent-policy input records consent item decisions for the authenticated user.
