Deciphering the hidden frame geometry in Ethereum account abstraction: EIP-8141's 64-frame transaction leap and the limits of next-step upgrades

Transaction 0xdeadbeef... (a placeholder placeholder hash) just failed in a testnet bundle. Not because of a revert, but because the new EIP-8141 frame wrapper refused to parse one of the 47 internal slices. Not a bug, not an outage. A protocol-level signal that Ethereum is ready to replace single-shot atomic transactions with session-level compound execution. This is the kind of quiet infrastructure move that usually gets buried under Pectra upgrade noise, yet its implications ripple far beyond gas optimization.
