# Chairman v4.0 analysis.php Integration

Files:
- analysis_chairman_v4_0_integrated.php
- legacy_analysis/analysis_v50_original_SOURCE.php

Install:
1. Backup current analysis.php.
2. Copy `analysis_chairman_v4_0_integrated.php` to your WinRacing root.
3. Test directly first.
4. If OK, rename to `analysis.php`.

New endpoint:
`analysis.php?wr_chairman_payload=1&race_date=YYYY-MM-DD`

UI:
A new Chairman Production Gateway panel appears above the analysis loading area after selecting a race date.

Safety:
- Original analysis logic is kept.
- Chairman error only shows in the new panel.
- Does not stop original Matrix / Strategy / Live Results.
