# Document Hierarchy

## Purpose
Avoid competing sources of truth.

## When to Use
Use when adding, moving, or adapting docs.

## Inputs
README, rules files, architecture docs, generated docs, indexes.

## Steps
1. Identify canonical docs.
2. Identify derived or generated docs.
3. Link instead of duplicating where possible.
4. Update indexes when hierarchy changes.

## Gates
The repository has one clear entry path and no accidental duplicate authority.

## Evidence
Updated indexes, links, and hierarchy notes.

## Anti-Patterns
Creating a second "main" guide with conflicting rules.
