v2.2.0 - Architecture-Driven Edge Case Testing

What's New

Architecture-Driven Edge Case Testing - Ralph now automatically detects architectural patterns in project documentation and adds corresponding edge-case tests.

Features

Ralph scans your CLAUDE.md or README for these patterns:

Pattern Detected	Test Added
offline sync / batch upload	Out-of-order event tests
idempotency / concurrent	Race condition tests
event-sourced / event handler	Missing dependency tests
retry / distributed	Partial failure tests

How It Works

1. After implementing happy-path tests
2. Ralph scans project docs for pattern keywords
3. If pattern found but edge-case test missing → adds it before completing story
4. If no patterns found → completes normally (zero overhead)

Benefits

• ✅ Catches real-world bugs (race conditions, offline sync issues, missing dependencies)
• ✅ Zero overhead for simple CRUD apps (only activates when patterns detected)
• ✅ General-purpose (works for any project)
• ✅ Simple keyword matching (no complex logic)

Real-World Impact

This feature would have caught 3 P1 bugs in production event-sourcing code:

• Race condition on idempotency keys (entire batch failed)
• Stats regression from out-of-order events (offline sync)
• Data loss when events arrived before dependencies

See CHANGELOG.md for full details.
