1//! # Lens Core - High-Performance Code Search Engine
2//!
3//! A production-ready code search engine with:
4//! - LSP-first architecture with real language server integration
5//! - Zero-copy fused pipeline for ≤150ms p95 latency
6//! - Bounded BFS for def/ref/type/impl traversal
7//! - SLA-bounded metrics: Success@10, nDCG@10, SLA-Recall@50
8//! - Built-in benchmarking and fraud-resistant attestation
9//!
10//! ## Architecture
