Error: KeyError: 'human' in /api/v2/cards/legal-check/gauntlet-9
Location: database/app/routers_v2/cards.py:242
Root cause: CARDSETS['gauntlet-9'] missing 'human' key in database/app/db_engine.py

All other gauntlet events (3-8) had 'human' key, but gauntlet-9 didn't.

Fix: Added to database/app/db_engine.py line 119:
'human': [x for x in range(1, 30)]

This allows the legal-check endpoint to validate which cardsets are allowed for human players in gauntlet-9.

Deployed: v1.5.5 to production (akamai/pd_api)
Verified: Container healthy, CARDSETS['gauntlet-9']['human'] present
