Module patterns 

Pattern matching infrastructure for identifying tools in Bash commands

This module provides efficient pattern matching using Aho-Corasick automaton to identify which tools (npm, cargo, git, wrangler, etc.) are being used in Bash command invocations from Claude session logs.

Architecture

• matcher: Core pattern matching trait and Aho-Corasick implementation
• loader: TOML-based pattern configuration loading
• knowledge_graph: Advanced pattern learning with voting and confidence scoring (includes caching)

Example

use terraphim_session_analyzer::patterns::{create_matcher, load_patterns};

// Load patterns from built-in TOML
let patterns = load_patterns()?;

// Create matcher
let mut matcher = create_matcher();
matcher.initialize(&patterns)?;

// Find matches
let matches = matcher.find_matches("npx wrangler deploy --env production");
for m in matches {
    println!("Found tool: {} at position {}", m.tool_name, m.start);
}
