# KOUCHA GOLD Late Single Fatal Exit Compare

This package contains the S2 comparison for A2_BASE / F1 / F2 / F3 / F4.

Primary validation files:
- run_status.csv
- input_preflight_validation.csv
- late_single_fatal_exit_s2_summary.csv

Important: tester logs are auxiliary only. Use PREFLIGHT_OK in run_status/input_preflight_validation for validation.

Result: no F pattern improved over A2_BASE in S2, so the remaining three segments were not run.
