What

Create CLAUDE.md files for all 8 ecosystem projects to provide AI development
context. This is the highest-impact documentation improvement — it directly
enhances AI-assisted development productivity.

Why

All 8 projects lack CLAUDE.md. When using AI tools (Claude Code, Copilot, etc.),
the absence of structured project context forces repeated manual explanation of
architecture, patterns, and constraints. A well-structured CLAUDE.md accelerates
AI-assisted workflows significantly.

Where

How

Each CLAUDE.md should follow this standard structure:

# {project_name}

## Overview
{Project purpose and core design philosophy — 1-2 sentences}

## Architecture
{Core module structure, dependency direction, key abstractions}

## Build & Test
{Build commands, test execution, CI configuration}

## Key Patterns
{Project-specific patterns: Result<T>, decorator, facade, RAII, etc.}

## Ecosystem Position
{Tier level, upstream/downstream dependencies}

## Dependencies
{External dependencies and ecosystem dependencies}

## Known Constraints
{Platform limitations, experimental features, breaking change warnings}

Per-Project Key Content

Acceptance Criteria

• CLAUDE.md exists in all 8 project roots
• Each file follows the standard structure above
• Ecosystem position and tier level documented
• Key patterns specific to each project are captured
• Build & test commands are verified to work
