+//! Matrix Multiplication Fragment Shader
+//!
+//! Computes C = A * B using texture-based GPU compute.
+//!
+//! ## Usage
+//!
+//! - A and B are R32F textures (single-channel float)
+//! - Output is rendered to framebuffer-attached texture
+//! - Each fragment computes one element of C
+//!
+//! ## Texture Layout
+//!
+//! - A: rows = M, cols = K (stored row-major)
+//! - B: rows = K, cols = N (stored row-major)
+//! - C: rows = M, cols = N (output)
+//!
+//! ## Performance Notes
+//!
+//! - Use texture size that's power of 2 for best performance
+//! - NEAREST filtering required for exact texel fetch
+//! - Loop unrolling may help on some GPUs

+//! WebGL2 compute simulation for GPU-accelerated operations
+//!
+//! Uses ping-pong texture rendering for matrix operations on devices without WebGPU.
+//! This approach treats textures as 2D arrays and uses fragment shaders for computation.
+//!
+//! ## Architecture
+//!
+//! ```text
+//! +-------------+     +----------------+     +-------------+
+//! |  Input A    | --> |  Fragment      | --> |  Output     |
+//! |  (Texture)  |     |  Shader        |     |  (Texture)  |
+//! +-------------+     +----------------+     +-------------+
+//!        ^                   |                      |
+//!        |                   v                      v
+//! +-------------+     +----------------+     +-------------+
+//! |  Input B    | --> |  Transform     | --> |  CPU Read   |
+//! |  (Texture)  |     |  Feedback      |     |  (Float32)  |
+//! +-------------+     +----------------+     +-------------+
+//! ```
+//!
+//! ## Limitations vs WebGPU
+//!
+//! - No true compute shaders (uses fragment shaders)
+//! - Limited to 2D texture operations
+//! - Readback through transform feedback or readPixels
+//! - Lower performance than WebGPU compute

+//! # Compute AMM (Automated Market Maker)
+//!
+//! An AMM for compute pricing in the edge-net P2P AI network.
+//! Uses a constant-product formula (x * y = k) with dynamic fees.
+//!
+//! ## Features
+//!
+//! - **Constant Product**: x * y = k invariant ensures liquidity
+//! - **Dynamic Fees**: 0.3% base to 3% at high utilization
+//! - **LP Tokens**: Liquidity providers receive proportional tokens
+//! - **Price Discovery**: Real-time compute pricing via market forces
+//!
+//! ## Example

+//! # Reputation Bonding Curves
+//!
+//! Economic mechanisms for reputation-based pricing and allocation.
+//! Implements bonding curves that reward high-reputation nodes with:
+//!
+//! - **Price Discounts**: Up to 20% discount for high-reputation nodes
+//! - **Priority Allocation**: Superlinear advantage for task allocation
+//! - **Stake Requirements**: Bonding curve for reputation-stake relationship
+//!
+//! ## Bonding Curve Model

+//! - Reputation 100: weight = 100^1.5 = 1000
+//!
+//! This creates strong incentives for maintaining good behavior.

+//! Entropy-Based Consensus for Swarm Intelligence
+//!
+//! Implements entropy-minimizing negotiation between swarm nodes.
+//! Consensus is achieved when belief entropy falls below threshold,
+//! indicating the swarm has converged to a shared decision.
+//!
+//! ## Theory
+//!
+//! Shannon entropy measures uncertainty in a probability distribution:
+//!   H = -SUM(p_i * log2(p_i))
+//!
+//! Low entropy = high certainty = convergence
+//! High entropy = uncertainty = negotiation needed
+//!
+//! ## Algorithm
+//!
+//! 1. Each node maintains belief probabilities for decisions
+//! 2. Nodes exchange beliefs with peers (gossip)
+//! 3. Beliefs are averaged: p_new = 0.5 * p_local + 0.5 * p_peer
+//! 4. Convergence when H < threshold (e.g., 0.1)
+//!
+//! ## References
+//!

+//! - Entropy-based stopping criteria

-//! - **Consensus**: Entropy-based distributed decision making
-//!   - Belief propagation
-//!   - Entropy minimization for convergence
-//!   - Byzantine fault tolerance
+//! ## Usage
 //!
-//! - **Collective**: Network-wide memory formation
-//!   - Hippocampal-inspired consolidation
-//!   - RAC-based pattern sharing
-//!   - Quality-gated storage
+//! ### Entropy Consensus
+//!
+//! ```rust,ignore
+//! use ruvector_edge_net::swarm::{EntropyConsensus, Decision};
+//!
+//! // Create consensus for task routing decision
+//! let consensus = EntropyConsensus::with_threshold(0.1);
+//!
+//! // Add options with initial beliefs
+//! consensus.set_belief(1, 0.6);  // Route to node 1
+//! consensus.set_belief(2, 0.4);  // Route to node 2
+//!
+//! // Negotiate with peer beliefs
+//! let peer_beliefs = peer.get_beliefs();
+//! consensus.negotiate(&peer_beliefs);
+//!
+//! // Check for convergence
+//! if consensus.converged() {
+//!     let decision = consensus.get_decision().unwrap();
+//!     println!("Consensus reached: route to node {}", decision);
+//! }
+//! ```
+//!
+//! ### Collective Memory
+//!
+//! ```rust,ignore
+//! use ruvector_edge_net::swarm::{CollectiveMemory, Pattern, RacEvent};
+//!
+//! let memory = CollectiveMemory::new("node-1");
+//!
+//! // Share a learned pattern
+//! let pattern = Pattern::new(
+//!     "task-routing-v1".to_string(),
+//!     vec![0.5, 0.3, 0.2],  // Embedding
+//!     0.95,                  // Quality
+//!     100,                   // Sample count
+//!     "node-1".to_string(),
+//! );
+//! let rac_event = memory.share_pattern(&pattern);
+//! swarm.publish(TOPIC_MODEL_SYNC, &serialize(&rac_event)?);
+//!
+//! // Receive pattern from peer
+//! let peer_event = deserialize::<RacEvent>(&data)?;
+//! if memory.receive_pattern(&peer_event) {
+//!     println!("Pattern accepted for consolidation");
+//! }
+//!
+//! // Consolidate during idle periods
+//! let consolidated = memory.consolidate();
+//! println!("Consolidated {} patterns", consolidated);
+//! ```
+//!
+//! ## Integration with RAC
+//!
+//! The swarm module uses RAC (RuVector Adversarial Coherence) for:
+//!
+//! 1. **Pattern Assertions**: Shared patterns are RAC Assert events
+//! 2. **Challenge/Support**: Disputed patterns can be challenged
+//! 3. **Authority Policies**: Only trusted nodes can deprecate patterns
+//! 4. **Audit Trail**: All pattern sharing is logged in Merkle tree
+//!
+//! ## References
+//!
+//! - DeGroot consensus model
+//! - Complementary learning systems theory
+//! - Federated learning pattern aggregation
