jgrusewski 7458f1be01 feat(wave12): E2E validation complete - 225-feature pipeline ready
 Validation Results:
- PPO training: 24.2s (1 epoch, 950 samples, dim=225)
- Feature extraction: 105μs/bar (9.5x faster than target)
- Model checkpoint: 293KB (147KB actor + 146KB critic)
- GPU memory: 145MB used (96.4% headroom)
- Zero dimension mismatches

📊 Success Criteria (5/5):
 Feature dimension = 225 (Wave C 201 + Wave D 24)
 Model state_dim = 225
 Training completed without errors
 Checkpoint saved successfully
 No dimension mismatch errors

📁 Training Data Ready:
- ES.FUT: 2.9MB, 180 days
- NQ.FUT: 4.4MB, 180 days
- 6E.FUT: 2.8MB, 180 days
- ZN.FUT: 65KB, 90 days (clean)

🚀 Next: Full production model retraining (4 models, ~10min GPU time)

//! Observability infrastructure for the Foxhunt HFT trading system.
//!
//! This module provides comprehensive observability capabilities including:
//! - Correlation ID generation and propagation across service boundaries
//! - Structured JSON logging with consistent format
//! - OpenTelemetry distributed tracing with Jaeger integration
//!
//! # Architecture
//!
//! The observability infrastructure follows a three-layer approach:
//!
//! 1. **Correlation Layer**: Generates and propagates correlation IDs across all services
//! via gRPC metadata, enabling request tracking across the entire system.
//!
//! 2. **Logging Layer**: Provides structured JSON logging with automatic correlation ID
//! injection, service identification, and log rotation.
//!
//! 3. **Tracing Layer**: Implements OpenTelemetry distributed tracing with parent-child
//! span linking, context propagation, and Jaeger export.
//!
//! # Usage
//!
//! ## Initialize Observability in Services
//!
//! ```rust,no_run
//! use common::observability::{init_observability, CorrelationId};
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//! // Initialize observability infrastructure
//! init_observability("trading_service", "localhost:6831").await?;
//!
//! // Correlation IDs are automatically propagated via gRPC metadata
//! Ok(())
//! }
//! ```
//!
//! ## Log with Correlation ID
//!
//! ```rust,no_run
//! use tracing::{info, error};
//! use common::observability::CorrelationId;
//!
//! async fn handle_request() {
//! let correlation_id = CorrelationId::new();
//!
//! info!(
//! correlation_id = %correlation_id,
//! "Processing trade request"
//! );
//! }
//! ```
//!
//! ## Create Traced Spans
//!
//! ```rust,no_run
//! use tracing::{info_span, instrument};
//!
//! #[instrument(name = "process_order", skip(order))]
//! async fn process_order(order: Order) -> Result<(), Error> {
//! // Span is automatically created and linked to parent context
//! Ok(())
//! }
//! ```

/// This is a convenience function that initializes both logging and tracing

///
/// # Arguments
///
/// * `service_name` - Name of the service (e.g., "api_gateway", "trading_service")
/// * `jaeger_endpoint` - Jaeger agent endpoint (e.g., "localhost:6831")
///
/// # Returns
///
/// Returns `Ok(())` on success, or an error if initialization fails.
///
/// # Example
///
/// ```rust,no_run
/// use common::observability::init_observability;
///
/// #[tokio::main]
/// async fn main() -> Result<(), Box<dyn std::error::Error>> {
/// init_observability("trading_service", "localhost:6831").await?;
///
/// // Service logic here...
/// Ok(())
/// }
