Block credit if the property overlaps an indigenous territory or appears on the IBAMA embargo list.

    "indigenous_overlap": {
      "source": "br:funai:indigenous-territories",
      "join": { "op": "intersects", "target": "$input" }
    },
    "embargo_overlap": {
      "source": "br:ibama:embargoed-areas",
      "join": { "op": "intersects", "target": "$input" }
    }
  },

  "checks": [
    {
      "id": "no_indigenous_overlap",
      "severity": "critical",
      "predicate": { "type": "exists", "set": "$indigenous_overlap" }
    },
    {
      "id": "no_embargo_overlap",
      "severity": "high",
      "predicate": { "type": "exists", "set": "$embargo_overlap" }
    }
  ]
}

Buffer around conservation units

Warn if the property is within 1 km of a federal conservation unit.

      "source": "br:icmbio:conservation-units",
      "join": {
        "op": "dwithin",
        "target": "$input",
        "distance_m": 1000
      }
    }
  },

  "projections": {
    "distance_to_uc": {
      "set": "$nearby_uc",
      "terminal": { "type": "min_distance_m", "target": "$input" }
    }
  },

  "checks": [
    {
      "id": "too_close",
      "severity": "medium",

Sanctions screening

Reject if the identifier matches a sanctions register.

      "predicate": { "type": "exists", "set": "$ofac_hits" }
    }

}

Call with the typed identifier:

{
  "input": {
    "scheme": { "type": "ofac:sdn", "value": "SDN-12345" }
  },
  "ruleset_id": "sanctions-screening@1"
}

Combined policy with custom verdict

Multiple checks across different severities, with an explicit verdict policy.

{
  "name": "combined-policy",

    "indigenous_overlap": {
      "source": "br:funai:indigenous-territories",
      "join": { "op": "intersects", "target": "$input" }
    },
    "nearby_uc": {
      "source": "br:icmbio:conservation-units",
      "join": {
        "op": "dwithin",
        "target": "$input",
        "distance_m": 500
      }
    }
  },

  "checks": [
    {
      "id": "no_indigenous",
      "severity": "critical",

      "id": "not_near_uc",
      "severity": "low",
      "predicate": { "type": "exists", "set": "$nearby_uc" }
    }
  ],

  "verdict_policy": {
