Debugging Tips

Error code lookup: Find the contract by prefix (first 3 digits), then specific error by suffix (last 3 digits)
Common patterns:
- xxx001 often means authorization failure (ERR-AUTH)
- xxx002-xxx008 often validation/state errors
DAO errors (100-300): Check multisig approval status and proposal state
Market errors (400): Usually health/collateral/oracle related
Vault errors (800-810): Check caps, pauses, balances, and flashloan permissions
