subcog/services/deduplication/
service.rs

1//! Deduplication service orchestrator.
2//!
3//! Coordinates the three-tier deduplication check:
4//! 1. **Exact match**: SHA256 hash comparison via tag search
5//! 2. **Semantic similarity**: Embedding comparison with configurable thresholds
6//! 3. **Recent capture**: LRU cache with TTL-based expiration
7//!
8//! Uses short-circuit evaluation, returning on first duplicate match.

26/// Service for deduplication checking.
27///
28/// Orchestrates three-tier deduplication:
29/// 1. Exact match (fastest) - SHA256 hash lookup
30/// 2. Semantic similarity - Embedding cosine similarity
31/// 3. Recent capture - In-memory LRU cache
32///
33/// Uses short-circuit evaluation: stops on first match.
