MITRE ATT&CK STIX data never includes primary_motivation on intrusion-set
objects. Motivation is now derived with a 3-tier fallback:
1. Curated MITRE-ID override map (100+ known groups mapped by hand)
2. STIX primary_motivation field (if MITRE ever adds it)
3. Description keyword inference (financ/ransomware/espionage/
nation-state/destructive/hacktivist patterns)
Re-running MITRE sync will now backfill motivation for existing actors.
