Concordance Maths v1.1

Original mathematics tasks with exact binary verification through a pinned OpenEnv runtime. Each row gives the public problem, data, image and task budget. Submit the requested JSON answer using the runtime operations. No private reference answers or qualification traces are included.

Selection combines historical Arena reward variation with separate local confirmation evidence. Historical zero rewards alone do not establish mathematical errors, and local confirmation is not Arena training or evidence of learning improvement. Task budgets are preserved per row. The image contains the trusted verifier; the policy interface exposes only the documented operations.

The selected 17 tasks comprise 13 tasks with historical Arena reward variation and four tasks that passed separate local 40-draw confirmations. The four local confirmations use eight groups of five draws each, retaining the first four valid terminal outcomes per group; the fifth outcome is preserved.
