# Pinned Submodule Versions

## Overview
This document tracks all pinned third-party submodules in the Pound project. Each submodule is locked to a specific commit hash to ensure reproducible builds and prevent unexpected updates.

## Update Policy
**NEVER update submodule commits without explicit approval from the project lead.** All updates must:
1. Be tested thoroughly
2. Have documented justification
3. Update this document with the new commit hash
4. Be committed as a separate, clear change
