Excuse me for cross-posting this in multiple issues/channels! But in the hopes of avoiding disruption to client team CIs...

Just a quick head's up for client teams: Future excution-specs fixture releases will follow a different directory layout (fixture formats themselves haven't changed). Please read more in announcment in the Eth R&D #el-testing channel.

But the TLDR is:
Previously, fixture JSON files accumulated test cases for every target fork in a single file, meaning each file grew with every new fork. Fixtures are now split into per-fork sub-directories, keeping file sizes bounded and letting you point your runner at exactly the fork you need to test.

And the layout is:

I would like to talk/discuss about testing/benchmarks on state and how to get to this state, especially big ones. How to init the chain? How can we improve the DevEx for people doing research on state? 😄 👍

We are working on a tool to directly launch clients into this big state: https://github.com/nerolation/state-actor/tree/main and could use help there 😄 👍
