# IMPLEMENTATION.md — Category 3 Audit

## Changes Made
- `scripts/status.py:698-703`: Replaced "future work" stub with `_audit_category3()` function call
- `scripts/status.py:605-660`: Added `_audit_category3()` function implementing git-based modification detection

## How It Works
- Checks `git diff --name-only HEAD` and `git diff --cached --name-only HEAD` for uncommitted changes
- Excludes files inside task folders (those are legitimate workflow artifacts)
- If no task is in implement/doc_review phase, all uncommitted changes outside task folders are flagged as violations
- If active edit tasks exist, changes outside task folders are reported as informational
- Handles missing .git directory gracefully
