Request:
- Analyze the current HK IPO batch from break probability, capital efficiency, and risk/reward.
- Test whether names such as 01688 deserve a higher defensive ranking than their heat score implies.
Changes:
- Added rules/ipo_break_risk_reward_v0.yaml as an experimental defensive overlay.
- Split the new framework into break protection, capital efficiency, and upside optionality.
- Added historical break-rate calibration anchors from analysis_model_v0_dataset.csv.
- Updated the 2026-06-22 IPO report with a defensive risk/reward ranking and dual execution guidance.
- Logged the rule change and its caveats.
Verification:
- Ran git diff --check and git diff --cached --check.
- Parsed the new YAML file with PyYAML.
- Recomputed key historical break-rate anchors from the current model dataset.
