zeekay f4ee7a0525 Publish under the org, not a person
Bylines, paper authorship, correspondence addresses and the founder blurb under
each post named an individual. They name the organisation that published the
work instead: the brand on posts and pages, the research byline on papers, and
research@ in place of a personal address. Both are what these repositories
already used elsewhere — nothing new was coined.

Co-authors are untouched. Where a paper named someone else alongside, they stay
named; only the one byline changed. Bibliography entries, running heads,
PDF metadata and affiliations move with it, so a citation still resolves to
whoever the cited paper names.

Sample and fixture data uses the placeholder name these tests already use
elsewhere, so no assertion changed meaning.

\begin{abstract}
Universal Liquidity is the order-execution layer of the Lux exchange.
It unifies three structurally different liquidity sources behind one
router and one atomic settlement contract: the Network's native
automated market makers (AMM~V2/V3 contracts and the V4 native
precompile at \texttt{0x9999}), a signed-quote private market maker
(PMM) that prices against and hedges on external venues, and external
on-chain DEX liquidity used only as a last resort. A single request
yields a single best-execution fill that succeeds in full or reverts
in full.
The paper formalizes four things. First, the \emph{signed-quote
request-for-quote (RFQ)} protocol: the market maker --- not the user
--- signs the price, so ``you will receive $y$'' is a cryptographic
commitment enforced on-chain, and a short, on-chain-checked expiry
eliminates the free-option (``last-look'') leak that defeats naive
RFQ designs. Second, the \emph{universal router}: best execution is
\emph{decided off-chain and settled on-chain}, never resolved inside
the settlement transaction. Third, the \emph{off-chain/on-chain
dividing line} as a design law --- a backend exists only where
off-chain state (price, inventory, hedge) is unavoidable, which is
why swap requires a backend and liquidity provision requires none.
Fourth, the \emph{post-quantum} unforgeability of the quote
commitment, inherited from the Lux PQ signature stack
(LP-073~Pulsar, ML-DSA-65; \cite{lp073,lp020}).
Section~\ref{sec:status} maps the design to the deployed system:
\texttt{luxfi/dex}, the \texttt{@luxamm} SDKs, the V2/V3 factory and
position-manager contracts live on Lux mainnet, the V4 precompile,
and the \texttt{exchange-api} settlement relayer.
