+//! # RuVector Edge - Distributed AI Swarm Communication
+//!
+//! Edge AI swarm communication using `ruv-swarm-transport` with RuVector intelligence.
+//!
+//! ## Features
+//!
+//! - **WebSocket Transport**: Remote swarm communication
+//! - **SharedMemory Transport**: High-performance local IPC
+//! - **WASM Support**: Run in browser/edge environments
+//! - **Intelligence Sync**: Distributed Q-learning across agents
+//! - **Memory Sharing**: Shared vector memory for RAG
+//! - **Tensor Compression**: Efficient pattern transfer
+//!
+//! ## Quick Start
+//!
+//! ```rust,no_run
+//! use ruvector_edge::{SwarmAgent, SwarmConfig, Transport};
+//!
+//! #[tokio::main]
+//! async fn main() {
+//!     let config = SwarmConfig::default()
+//!         .with_transport(Transport::WebSocket)
+//!         .with_agent_id("agent-001");
+//!
+//!     let mut agent = SwarmAgent::new(config).await.unwrap();
+//!     agent.join_swarm("ws://coordinator:8080").await.unwrap();
+//!
+//!     // Sync learning patterns
+//!     agent.sync_patterns().await.unwrap();

+//! Zero-Knowledge Financial Proofs
+//!
+//! Prove financial statements without revealing actual numbers.
+//! All proofs are generated in the browser - private data never leaves.
+//!
+//! # ⚠️ SECURITY WARNING ⚠️
+//!
+//! **THIS IS A DEMONSTRATION IMPLEMENTATION - NOT PRODUCTION READY**
+//!
+//! The cryptographic primitives in this module are SIMPLIFIED for educational
+//! purposes and API demonstration. They do NOT provide real security:
+//!
+//! - Custom hash function (not SHA-256)
+//! - Simplified Pedersen commitments (not elliptic curve based)
+//! - Mock bulletproof verification (does not verify mathematical properties)
+//!
+//! ## For Production Use
+//!
+//! Replace with battle-tested cryptographic libraries:
+//! ```toml
+//! bulletproofs = "4.0"           # Real bulletproofs
+//! curve25519-dalek = "4.0"       # Elliptic curve operations
+//! merlin = "3.0"                 # Fiat-Shamir transcripts
+//! sha2 = "0.10"                  # Cryptographic hash
+//! ```
+//!
+//! ## Supported Proofs (API Demo)
+//!
+//! - **Range Proofs**: Prove a value is within a range
+//! - **Comparison Proofs**: Prove value A > value B
+//! - **Aggregate Proofs**: Prove sum/average meets criteria
+//! - **History Proofs**: Prove statements about transaction history
+//!
+//! ## Cryptographic Basis (Production)
+//!
+//! Real implementation would use Bulletproofs for range proofs (no trusted setup).
+//! Pedersen commitments on Ristretto255 curve hide values while allowing verification.

+//! Production-Ready Zero-Knowledge Financial Proofs
+//!
+//! This module provides cryptographically secure zero-knowledge proofs using:
+//! - **Bulletproofs** for range proofs (no trusted setup)
+//! - **Ristretto255** for Pedersen commitments (constant-time, safe API)
+//! - **Merlin** for Fiat-Shamir transcripts
+//! - **SHA-512** for secure hashing
+//!
+//! ## Security Properties
+//!
+//! - **Zero-Knowledge**: Verifier learns nothing beyond validity
+//! - **Soundness**: Computationally infeasible to create false proofs
+//! - **Completeness**: Valid statements always produce valid proofs
+//! - **Side-channel resistant**: Constant-time operations throughout
+//!
+//! ## Usage
+//!
+//! ```rust,ignore
+//! use ruvector_edge::plaid::zkproofs_prod::*;
+//!
+//! // Create prover with private data
+//! let mut prover = FinancialProver::new();
+//! prover.set_income(vec![650000, 650000, 680000]); // cents
+//!
+//! // Generate proof (income >= 3x rent)
+//! let proof = prover.prove_affordability(200000, 3)?; // $2000 rent
+//!
+//! // Verify (learns nothing about actual income)
+//! let valid = FinancialVerifier::verify(&proof)?;
+//! assert!(valid);
+//! ```
