I ran the flow with an hermes and an openclaw agent. These changes mark "Privy" fully optional (but recommended). I tested this with a self maintained wallet and a full privy "agentic wallet" onramp (it mustn't be a concern of this skill, consumers must never be forced to use some service provider or wallet when interacting with a sufficiently permissionless protocol).

both URLs are created and don't work - that's 100% out of this PR's scope. The IPNFTs are on chain, the "labs" are created, all EIP-712 signatures worked, x402 payments worked.

Ideally incorporate these changes with your upcoming PR on the new lab creation flow ( #2 )

If it would then the links should also work. How did you validated that the labs were created? Also can you check file upload please? If labs would be created the the file upload would also work.
I created a new PR for OCL changes. I thought we discussed that we will wait until OCL is in place, before adding some changes. Because OCL PR should have some adjustments to optional privy wallet usage.

I started this already on Thursday. If you remove privy as hard dependency I'm fine. On your PR I see that the env vars are still mandatory. Your staging backend does reply with hard error messages, I filed them. The most recent one being that my token isn't "whitelisted". that's imo completely out of scope of this pr. If you don't like it never mind, merge yours first and apply my original prompt again if necessary.
