client.alpha.infer() and client.llm.chat() both failing on testnet

[addnad]

Bug Report

Issues Found

1. On-chain ONNX inference (client.alpha.infer) — no logs emitted
Transactions succeed (Status 1, gas consumed) but emit 0 logs, causing:
OpenGradientError: InferenceResult event not found in transaction logs

Tested with:

• Iris classifier CID: -u43xg03ZFZRDPRGrPND--FN3Bs5kwwIG1_8XdtO9yM
• Custom uploaded model CID: MXdc3sFWJlmtTYCGlGqWtmyCXq9Xon4x5TJJVPBsW3M
• OpenGradient precompile: 0x00000000000000000000000000000000000000F4
• Node API fallback: sdk-devnet.opengradient.ai returns HTTP 500

2. TEE LLM inference (client.llm.chat) — HTTP 500
llm.opengradient.ai/v1/chat/completions returns 500 on POST.
OPG Permit2 approval succeeds. Wallet has 0.1 OPG on Base Sepolia.

Environment

• SDK version: 0.7.4
• Wallet: 0x13F0775b1BA55280613159fAF52417885091ffC1
• OG testnet balance: ~0.06 tokens
• Base Sepolia OPG: 0.1 tokens

Expected

Both inference methods should return results.

Is this a known testnet issue? Is there a workaround?
