Order_version_mismatch on all market orders since April 30, 2026

[mupeler98-del]

SDK version: 0.34.6
Error: PolyApiException[status_code=400, error_message={'error': 'order_version_mismatch'}]

All market orders fail with this error since April 30, 2026.
Same code worked April 25-27.

Tried:

• Both neg_risk True and False
• signature_type 1 and 2
• Regenerated API credentials
• Various order sizes (1+ shares minimum)

Server seems to expect a different EIP-712 schema/version that
SDK 0.34.6 doesn't generate.
