Arena Compare: arena_duel_bty_1e5cf83a-fe72-4b09-92a8-6ef1c513aebc_1771616207033
Transparent contender comparison across model/harness/tool stack, contract checks, and objective scoring.
Reviewer drill-down
Arena review workflow context
Use this page when you need the comparative decision surface: winner rationale, review thread, calibration, autopilot posture, and the contender evidence matrix in one place.
Evidence anchor
Real artifact anchor: artifacts/arena/arena_bty_arena_001/summary.json + artifacts/ops/arena-productization/2026-02-20T02-18-40Z-agp-us-060-execution-submission-autopilot/summary.json.
The arena compares contenders against one bounty decision surface.
Reason codes explain why the winner cleared policy and scoring gates.
Autopilot evidence proves live readiness instead of implying it.
