chunter-cb submitted a companion EIP to EIP-8130 for consensus-driven pruning of expired actors, bounding Keystore state growth from short-lived actors such as session keys and subscriptions. Mike Neuder published "ePBS, distilled", outlining ePBS in its final form and its effect on MEV markets. The justification for EIP-8037's system call storage write bound was corrected and merged. AA (Frame Tx) breakout #2 was held in the evening.

State growth in the 8130 Keystore

New EIP: Keystore expired actor pruning

(chunter-cb), submitted and marked WIP; EIP-8396 per Ethereal news #37. It has two parts: a layout enshrined at launch, fixing an actor's `actor_config`, `policy_manager` and `policy_commitment` as a co-located, stride-aligned 3-word record with a `CLEANABLE` marker bit in the `actor_config` reserved region; and a best-effort reaper that, each block, walks a bounded number of record heads from a deterministic block-seeded position and clears expired actors.
