Crate sdivi_patterns 

Pattern fingerprinting and catalog for sdivi-rust.

Implements Stage 4 of the five-stage analysis pipeline. Classifies pattern hints into the five built-in categories, fingerprints their structural shapes with blake3, and assembles a PatternCatalog with per-category entropy.

Design constraints

This crate must NOT depend on sdivi-graph or sdivi-detection.

Quick start

use sdivi_patterns::PatternCatalog;

let catalog = PatternCatalog::default();
assert!(catalog.entries.is_empty());
