MaxMind DB is prefix-keyed. ASNForge MMDB maps IP address to compact origin ASN profile data.
Do not expect ASN -> profile lookup from the MMDB. Use asnforge-asn.jsonl or asnforge-asn.csv for direct ASN lookup.
The MMDB intentionally excludes full origin ASN arrays, detailed MOAS state, collector observations, and long provenance objects by default. Those details live in asnforge-prefixes.jsonl and .csv to preserve MMDB data-section deduplication.
Ambiguous MOAS prefixes can be represented with moas=true; selected-origin behavior is controlled by moas_policy.
