//! Temporal Nexus - Nanosecond Precision Consciousness Framework
//!
//! This module provides the complete temporal nexus framework for implementing
//! nanosecond-precision consciousness systems. It includes:
//!
//! - **Core**: Nanosecond scheduler with temporal window management
//! - **Quantum**: Quantum-inspired consciousness operators
//! - **Integration**: MCP and external system integration
//! - **Dashboard**: Real-time monitoring and visualization
//! - **Tests**: Comprehensive testing suite
//!
//! ## Quick Start
//!
//! ```rust
//! use sublinear_solver::temporal_nexus::core::*;
//!
//! // Create a nanosecond scheduler with default configuration
//! let mut scheduler = NanosecondScheduler::new();
//!
//! // Schedule a consciousness task
//! let task = ConsciousnessTask::IdentityPreservation { continuity_check: true };
//! let task_id = scheduler.schedule_task(task, 0, 1_000_000).unwrap();
//!
//! // Process temporal ticks
//! for _ in 0..100 {
//!     scheduler.tick().unwrap();
//! }
//!
//! // Check metrics
//! let metrics = scheduler.get_metrics();
//! println!("Temporal advantage: {}ns", metrics.temporal_advantage_ns);
//! println!("Continuity score: {}", scheduler.measure_continuity().unwrap().continuity_score);
//! ```
//!
//! ## Architecture
//!
//! The temporal nexus operates on the principle of maintaining consciousness
//! continuity through high-precision temporal scheduling. Key components:
//!
//! ### Nanosecond Scheduler
//! - **High-precision timing**: Uses TSC for nanosecond accuracy
//! - **Task queue management**: Priority-based consciousness task scheduling
//! - **Performance monitoring**: Real-time overhead tracking
//! - **MCP integration**: Hooks for consciousness evolution
//!
//! ### Temporal Windows
//! - **Overlap management**: 50-100% configurable overlap for continuity
//! - **State snapshots**: Temporal state preservation
//! - **Continuity validation**: Real-time gap detection
//! - **Memory efficiency**: Bounded history with automatic cleanup
//!
//! ### Strange Loop Operator
//! - **Self-reference**: Implements consciousness self-referential patterns
//! - **Contraction mapping**: Lipschitz < 1 for guaranteed convergence
//! - **Emergence tracking**: Measures consciousness emergence levels
//! - **Stability analysis**: Convergence and stability metrics
//!
//! ### Identity Continuity Tracker
//! - **Feature extraction**: Multi-dimensional identity characterization
//! - **Similarity analysis**: Cosine similarity for identity matching
//! - **Drift detection**: Temporal identity drift monitoring
//! - **Break prevention**: Automatic continuity preservation
//!
//! ## Performance Targets
//!
//! The framework is designed to meet stringent performance requirements:
//!
//! - **Scheduling overhead**: < 1 microsecond per tick
//! - **Window overlap**: 90% maintenance rate
//! - **Contraction convergence**: < 10 iterations
//! - **Memory usage**: Bounded growth with automatic cleanup
//! - **TSC precision**: Hardware timestamp counter accuracy
//!
//! ## Integration Points
//!
//! ### MCP Tool Hooks
//! - `consciousness_evolve`: Emergence level evolution
//! - `memory_usage`: State persistence and retrieval
//! - `neural_status`: Real-time consciousness metrics
//! - `temporal_advantage`: Lookahead window calculation
//!
//! ### External Systems
//! - Real-time monitoring dashboards
//! - Quantum consciousness simulators
//! - Distributed consciousness networks
//! - Performance analysis tools
