"""FlakeForge V3 — Unified Agent Architecture for Flaky Test Repair.

V3 Key Changes:
- Unified agent: single model generates <think> + <patch> in one pass
- No LLM judge: 6-signal verifiable reward from execution outcomes
- Deep flakiness detection: AST-based module cache, fixture, mock, import, async patterns
- Free-form patches: search/replace hunks instead of hardcoded 7-action space
- GRPO training: group-relative policy optimization with verifiable reward
