Inspect source, license, environment and execution evidence before preparing. Preparation and execution are separate actions.

Success condition

Exit 0, status=task_complete, success=true, finite outputs satisfying interface.output_schema and all declared numerical/model checks. This is not a physical robot or general task-success claim.

Recorded evidence

task_complete: Three frozen positive cases passed against this exact adapter; see per-case receipts. This does not estimate general accuracy.
