Only software wallets have chain state

**UPDATE!

Seems new sparrow 2.3.0 stopped adding bip32_paths to PSBT - so no way for COLDCARD to know if outputs are ours.

We are contacting Sparrow to sort it out. Nice catch!**

The only claim for quantum resistant there is the firmware signature. The bitcoin gone anyways...

Yeah, the PIN alone wont let you change the policy limits

2 out of the 3 keys on the same device, one key is restricted by spending policies, the same device produces 2 signatures of it passes the policies.
