py_clob_client 0.34.6 + signature_type=2 passes auth but fails "invalid order version" — which SDK version works?

[jxu218382-spec]

I've been debugging this for nearly a month. Here's the deadlock:

SDK	signature_type	Result
py_clob_client 0.34.6	2	✅ Auth passes, ❌ "invalid order version"
py_clob_client_v2 1.0.1	2	❌ "maker address not allowed"
py_clob_client_v2 1.0.1	3	❌ "signer address has to be the address of the API KEY"

The old SDK with signature_type=2 gets past authentication — only the order format is rejected.

Which SDK version and .env configuration are you using for 5min-btc-polymarket? Is there an intermediate version that supports both the new order format AND signature_type=2?
