The seven engine specifications (lux-{photon,wave,nova,nebula,prism,ray,field}-protocol)
were fragmented short notes documenting layers of the same Quasar consensus stack.
This commit merges them into a single canonical reference, lux-consensus-engines.tex,
that uses one preamble, one set of theorems, one bibliography, and one composition
chapter showing how the engines layer into the LP-020 finality pipeline.
The seven originals are reduced to single-page breadcrumb stubs pointing at the
consolidated paper; their sections/ content is preserved on disk for git history.

- bibliography: consolidated from the seven original thebibliography blocks

\section{Introduction}
|
|
|
|
\label{sec:ray-introduction}
|
|
|
|
Existing metastable consensus protocols use fixed parameters $(k, \alpha, \beta)$ tuned
|
|
for worst-case adversarial conditions. This means that even in benign network conditions
|
|
(no Byzantine validators, low latency), transactions must wait for the same number of
|
|
confirmation rounds as under attack. This paper introduces the Ray protocol, which
|
|
adapts its finality threshold in real-time based on observed network behavior.
|
|
|
|
The key insight is that the \emph{rate} at which confidence accumulates carries
|
|
information about the adversarial environment. Rapid, unanimous convergence suggests
|
|
benign conditions where fewer confirmation rounds suffice. Slow, contested convergence
|
|
suggests adversarial interference requiring more rounds.
