\section{Composition with Sibling LPs}
|
|
\label{sec:composition}
|
|
|
|
The ZAP Stack is the umbrella. Every other architectural LP in the
|
|
new network is one layer of this stack or one orthogonal extension of
|
|
it. The composition table below is the canonical map.

|

model.}

|
\subsection{Reading the table}
|
|
|
|
Every cell in the ``Layer'' column points to one row of
|
|
Table~\ref{tab:tenlayer}. An LP that spans multiple layers (LP-202
|
|
pipelining touches ZapDB layer~1 and the executor layer~7; LP-218
|
|
rollup touches the frame layer~0, the schema layer~2, and the
|
|
executor layer~7) is honestly multi-layer; we do not pretend
|
|
otherwise.
|
|
|
|
\subsection{What is NOT yet decomplected}
|
|
|
|
Honest accounting. The architecture is the ten-layer model; the
|
|
following are residual migrations of legacy code paths to the
|
|
already-decomplected architecture, not architectural blockers.
|
|
|
|
\begin{itemize}[leftmargin=2em,nosep]
|
|
\item Twelve \texttt{codec.Manager} imports remain in the node. The
|
|
\texttt{Tx.Sign} cascade in \texttt{platformvm} and \texttt{xvm}
|
|
still routes through \texttt{codec.Manager} for the signing step.
|
|
The wire format on either side of Sign is ZAP; the bridge is a
|
|
transitional shim.
|
|
\item The legacy \texttt{lux/codec/} module is not yet archived.
|
|
Transitively pulled via \texttt{luxfi/vm/chains/atomic}. Module
|
|
deletion is gated on the \texttt{Tx.Sign} migration above.
|
|
\item \texttt{luxfi/p2p} still imported in eleven files. LP-201
|
|
replaces it with QUIC + ZAP + mDNS + DHT. The replacement is in
|
|
flight, not landed.
|
|
\item \texttt{service/info} blocked on \texttt{luxfi/p2p} upstream
|
|
codec/jsonrpc. The info-service public API still speaks the legacy
|
|
jsonrpc envelope on top of \texttt{luxfi/p2p}'s codec. Replaced
|
|
when LP-201 lands.
|
|
\end{itemize}
|
|
|
|
None of the above mutate the architecture. The architecture is the
|
|
ten-layer model. These are residual migrations.
