Document Integrity Layer

Detect LLM-induced document corruption before it ships.

What is this?

Document Integrity Layer is a Git pre-commit hook and web dashboard that catches document corruption introduced by AI assistants in real-time. It scans Word, PDF, and Markdown files for hallucinated citations, broken cross-references, malformed tables, and formatting inconsistencies—then generates audit trails proving exactly what changed and why. Built for developers and technical writers who delegate writing to Claude, ChatGPT, or similar tools and need verification that the AI didn't silently break your work.

Features

• Git pre-commit scanning — Automatically checks staged documents before commits
• Multi-format support — Analyzes .docx, .pdf, and .md files with semantic understanding
• Corruption detection — Identifies hallucinated URLs, broken internal links, table structure corruption, and citation inconsistencies
• Web dashboard — Visual history of all integrity checks across your repository
• Audit trails — Export compliance-ready reports showing what changed and when
• Slack/Discord alerts — Real-time notifications when corruption is detected
• Custom rule configuration — Define project-specific validation rules in .dil.toml
• Docker-ready — Run locally or containerized; no external dependencies required

Quick Start

Installation

pip install document-integrity-layer

Setup

Initialize in your repository:

dil init

This creates .dil.toml with default configuration. Install the Git hook:

dil install-hook

Configuration

Edit .dil.toml to customize detection rules:

[scanner]
check_citations = true
check_cross_references = true
check_table_integrity = true
check_formatting = true

[alerts]
slack_webhook = "https://hooks.slack.com/services/YOUR/WEBHOOK"

Usage

CLI

Run a one-time scan:

dil scan document.docx

Scan an entire directory:

dil scan ./docs --recursive

View integrity history:

dil history

Web Dashboard

Start the dashboard server:

dil server --port 8000

Navigate to http://localhost:8000 to explore:

• Scan history across commits
• Corruption reports with side-by-side diffs
• Citation and link validation results
• Custom audit exports

Pre-commit Hook

Once installed, the hook runs automatically:

git add my-document.docx
git commit -m "Update docs"
# → Pre-commit hook scans my-document.docx
# → Reports corruption if found
# → Blocks commit if severity threshold exceeded
