A July commit removed eight papers on the premise "no license — DEX/non-custodial only". That premise is wrong: Lux operates an ATS, a broker-dealer, a transfer agent and a bank, and this material is resold at lux.financial. The merge that brought main in preserved the removal because the commit stated a reason, which is how a stale reason outlives the fact it rested on. Back, at the versions main carried — main never received the removal, so its copies are the later ones: the ATS architecture, the security-token standard, smart order routing, institutional custody, MPC custody, post-quantum securities, the SSB partnership and the CoinBridge brief. 83 files.

The core properties are mechanized in Lean~4:
|
|
|
|
\begin{itemize}[nosep]
|
|
\item \texttt{Crypto.Threshold.CGGMP21}: keygen correctness,
|
|
identifiable abort, presignature one-time use, offline/online
|
|
separation, key never reconstructed.
|
|
\item \texttt{Crypto.FROST}: correctness, unforgeability, robustness,
|
|
majority threshold safety, share refresh.
|
|
\item \texttt{Crypto.Threshold.Reshare}: public key preservation,
|
|
old share invalidation, threshold maintenance, no key
|
|
reconstruction, Byzantine safety.
|
|
\item \texttt{Crypto.NonCustodial}: 2-of-3 non-custodial guarantee,
|
|
liveness (any 2 can sign), single-party impotence.
|
|
\end{itemize}
