zeekay dd93cb41f7 papers: cover-consistency + build pass on Lux Tier-2/3 catalogue
Sweep across the non-Tier-1 paper catalogue (Tier-1 owned by parallel
agent and excluded). All 113 processed papers already had luxcover
wired up; this commit fixes 14 build breakers and produces fresh
PDFs across the catalogue.

Fixes:
- lux-blockchain-scaling-laws: em-dash inside lstlisting -> --
- lux-corona-pq: stale \input pointing at 03-the-corona-scheme renamed
  to 03-the-corona-scheme (file already renamed on disk)
- lux-lattice-cryptography-primer: same Corona->Corona rename
- lux-formal-verification-lean4: Lean source uses unicode (×, ∀, ∃, ∈,
  ∧, ∨, ∩, ≠, ⟨, ⟩, ·, ¬) inside lstlistings. Added a literate map
  so listings render the math glyphs without UTF-8 fault.
- lux-id-did-specification: ✓/✗ in tabular replaced with \ding{51}
  / \ding{55} (pifont). Added pifont package.
- lux-ntt-simd-implementation: middle-dot in Go assembly listings;
  added literate {·}{\textperiodcentered}.
- lux-ntt-transform: μ, ×, –, — in regular text (no T1 fontenc).
  Replaced with $\mu$/$\times$/--/--- via unicode->latex sweep.
- lux-perpetuals-derivatives, lux-quantum-consensus,
  lux-quasar-consensus, lux-tee-computing-mesh: same unicode->latex
  sweep across body text. Also fixed broken math segment
  `$L_{avg} = 10$\times$$` -> `$L_{avg} = 10\times$`.
- lux-zchain: emoji glyphs in roadmap table replaced with
  parenthetical text.
- lux-triple-proof-consensus: dropped duplicate \usepackage{geometry}
  that clashed with luxcover (geometry option clash).
- pq: defined missing \Rq macro.

PDFs rebuilt for the full Tier-2/3 set.

Excluded (Tier-1, parallel agent): lp-073-pulsar, lp-stricte2epq,
dag-evm-formal, lp-010-quasar-stm-{3,4}, lp-020-quasar-consensus,
lux-institutional-custody, lux-nist-mptc-submission, pqsafe-il5,
pq-rns, plus shared/ and lps/.

\begin{abstract}
We present Fast Probabilistic Consensus (FPC), a novel Byzantine fault-tolerant consensus protocol that achieves agreement through adaptive threshold voting with phase-shift dynamics. FPC employs a sigmoid cooling function to transition from exploration ($\theta = 0.5$) to exploitation ($\theta = 0.8$) phases, enabling rapid convergence while preventing metastability. The protocol achieves $\varepsilon$-consensus with $\varepsilon = 2^{-\lambda}$ where $\lambda = \beta \cdot k \cdot (\theta - 0.5)^2$, tolerating up to $f < n/3$ Byzantine nodes. Through committee sampling of size $k = 20$-$30$ validators and requiring $\beta = 5$-$10$ consecutive confident rounds, FPC finalizes transactions in 1-3 seconds with message complexity $O(k \log n)$. We demonstrate FPC's integration within the Lux consensus stack, where it operates as the ``wave'' layer in a physics-inspired consensus architecture. The Zero-copy Application Protocol (ZAP) replaces gRPC+Protobuf for consensus messaging, achieving 9.69M messages/second with a $14\times$ deserialization improvement over Protobuf. FPC's safety, liveness, and BFT tolerance properties have been formally verified in Lean~4 with machine-checked proofs. Simulation results show 99.999\% safety with logarithmic scaling properties suitable for global networks of 100,000+ nodes.
