Call summary

•CL spec release to target ~5 days before FOCIL devnet 8 (first week of August); local interop between Lodestar and Besu to follow - 00:35:21

Spec Updates:
- ·Open question: whether `blockHash` param in `getInclusionList` Engine API is necessary if CL/EL share the same head; needs further analysis before merging Engine API PRs - 00:09:00
- ·EL store revamp planned: signed IL storage, request-response feeding into EngineList, and replacing inclusion committee route with dependent route (consensus-specs PR #5424, #5460) - 00:18:29
- ·Paris spec question raised: initial payload requires empty transaction set — Jihoon to investigate whether this needs updating for FOCIL (IL transactions could be included from block start) - 00:20:45
- ·Request-response for ILs: intended only for proposers and builders, not attesters; spec should clarify this - 00:24:07
Devnet Planning:
- ·Local interop tentatively planned between Lodestar and Besu on Alpha 12 ahead of FOCIL devnet - 00:33:45
- ·Next CL spec release targeted a few days before devnet 8 (~first week of August); waiting on EL store revamp to complete first - 00:35:21
Testing Progress:
- ·Lodestar blocked on EIP-7688 changes merging to unstable before rebasing; expects to target devnet 7 - 00:07:23
- ·Besu on Glamsterdam devnet 6; last run two weeks ago was not working - 00:07:52
- ·Yochum to start adding execution tests for FOCIL this week - 00:08:33
