\section{Wire Schemas}

LP-211 introduces six new ZAP wire schemas, allocated in the LP-208
|
|
extension range (\texttt{0xE2}--\texttt{0xE7} = LP-208/209/210/211
|
|
cluster):

|
|
Schemas \texttt{0xE0}--\texttt{0xE1} are reserved for LP-208 DAG
|
|
header/parent-list wire formats per LP-208's schema allocation.
|
|
Schema \texttt{0xE0}--\texttt{0xEF} as a whole is allocated to the
|
|
rollup-VM envelope range by LP-218, but with LP-208/LP-211 taking
|
|
\texttt{0xE0}--\texttt{0xE7}, leaving \texttt{0xE8}--\texttt{0xEF}
|
|
free for LP-218 rollup envelopes (\texttt{0xE0}--\texttt{0xE3} per
|
|
LP-218 itself for \texttt{RollupBatchTx},
|
|
\texttt{RollupChallengeTx}, \texttt{RollupExitTx},
|
|
\texttt{RollupGenesisTx}). The schema allocation map at the
|
|
umbrella (LP-200) reconciles the overlapping ranges.
