## Summary

Mantic is a **context-aware code search engine** that prioritizes **relevance over raw speed**. After testing across 5 repositories (cal.com, next.js, tensorflow, supabase, chromium), it demonstrates **superior result quality** compared to grep/ripgrep, despite some trade-offs in speed for very large codebases.

**Overall Assessment**: 4/5 - Excellent for AI agents, good for developers, needs speed optimization for 100K+ file repos.

## What's New in v1.0.25

**Enterprise-Grade Context Infrastructure**

- **Semantic Reranking (Hybrid Intelligence)**: Combines heuristic speed with neural understanding. Uses local embeddings (`transformers.js`) to find "conceptually relevant" code even without exact keyword matches.
  - Usage: `mantic "verify user" --semantic`
- **Code Intelligence**: Deep understanding of your codebase structure using Tree-sitter.
  - **Go to Definition**: `mantic goto UserService` returns the exact line number across your entire monorepo.
  - **Find References**: `mantic references handleLogin` finds every usage, respecting `.gitignore`.
- **Learned Context (Team Memories)**: Mantic now remembers which files solved previous queries. These patterns are saved locally (`.mantic/search-patterns.json`) and can be committed to git to share knowledge across your team.
- **Python Support**: Now includes first-class support for Python imports in the dependency graph.
- **Security & Stability**: 
  - Regex DoS protection for user inputs.
  - Command injection mitigations for VS Code extension.
  - Safe fallback for non-git directories (scans allow-listed extensions).

**Performance Update**: v1.0.25 is **~2x faster** than previous versions, scanning Chromium (481K files) in <2 seconds.

**Tested on 481K files (Chromium) with 100% multi-repo accuracy.**

## About the Project

Mantic is an infrastructure layer designed to remove unnecessary context retrieval overhead for AI agents. It infers intent from file structure and metadata rather than brute-force reading content, enabling retrieval speeds faster than human reaction time.

### Key Benefits

- **Speed**: Retrieval is consistently under 500ms for
