\section{Metaverse Companion}
\label{sec:metaverse}
\subsection{2021 Commitment}
\S23 described a metaverse companion that follows the user across
surfaces, persists state, and integrates with games (mini-games,
Coin Runner, Memory Bridge --- \S24).
\subsection{2025-12-15 Realization}
The companion is the persistent avatar binding the user's Zoo DID
(\textsc{zip-0033}) to:
\begin{itemize}[nosep,leftmargin=1.2em]
\item Wallet (Lux Wallet, white-label per \textsc{lp-134}).
\item \NFT{} portfolio (Zoo \NFT{} Liquidity Protocol,
\texttt{contracts/specs/zoo-nft-liquidity-protocol.md}).
\item Chat (Zoo Desktop avatar, \S\ref{sec:cute-ai}).
\item \AR{} (Zoo Field, \S\ref{sec:ar}).
\item Virtual Habitat Simulation (\textsc{zip-0300}).
\item Multiplayer Conservation Game (\textsc{zip-0303}).
\item Spatial Web agents (\textsc{zip-0011}, \textsc{zip-0433}).
\end{itemize}
\subsection{State Continuity}
The companion's state (XP, KEEPER, attestations, semantic memory) is
canonically held under the user's Zoo DID. Every surface reads from
A-Chain attestation; writes back through Hanzo \AI{} Chain receipts.
Cross-surface continuity is therefore a function of identity, not a
function of any single platform.
\subsection{Game-Asset Interoperability}
\textsc{zip-0304} (Game Asset Interoperability) defines how items move
across mini-games. \textsc{zip-0210} (Cross-Collection Composability)
defines how Zoo \NFT{}s compose with non-Zoo collections through
attested trait inheritance.
\subsection{Why Holographic}
The companion realizes the ``holographic'' axis named in the 2021
paper's 2025 update (\S28): every sub-DAO, per-\textsc{llm} chain, and
regional chapter inherits the same governance topology and the same
identity primitive. Whether the user is on Desktop, Field (\AR{}), the
DEX, or a sub-DAO sub-domain, the same DID drives the same companion.
That is the engineering meaning of ``holographic'' in 2025-12-15
\Zoo{}: a single template, replicated across every surface, anchored
on the same chain.
