Bash SFT note 02 evidence
Sanitized aggregate packet for the cumulative Session 2 report and its 21 August 2026 fair-base correction.
Boundary: The original strict stock 0/98 is response-contract-confounded. Under identical contract-calibrated generation, stock passed 8/98 and Arm 2 passed 89/98. This remains a within-generator selection score, and the selected model failed the one generator-independent canary.
