Reasoning-Mas-Flag-Drift

The model receives the prompt (and optional system message). The run uses scorer rubric_json_metrics with the JSON configuration below. Pass/fail and partial credit are determined entirely by that scorer against the model output; no human grading.

Return JSON only with keys answer, evidence, constraints. Config says flag checkout_v2 is off for EU, but trace shows EU request using CheckoutV2 handler. Identify the likely artifact conflict.
