You successfully submitted a PR! Due to the amount of PRs coming in: we will only look at PRs that the CI is happy with. We can also not hold your hand getting the CI green - just look how others that where merged did it and RTFM. So as long as there is any CI check that reports an error - no human will look at this. You might be able to ask for some support after supporting the project - e.g. by sending funds to lists.eth. When you fixed things after a requested change - then you also need to (re-)request a review.

Hi @ligi — conflicts are resolved. Here's what was updated since your May 11 review:

• Removed Ethereum Mainnet endpoint (was causing flaky dex.guru CI failures)
• Restored all upstream entries cleanly (no removals, pure addition)
• Switched to compact JSON array format matching upstream style

All 4 CI checks are passing. Branch is now updated with master.

Would appreciate a re-review when you have a moment. Thank you.
