Benchmark-shaped RL environments

Turn a benchmark ceiling into a renewable training surface.

Each family starts from a capability contract, then expands into original tasks, executable environments, graders, trajectories, failure labels, repairs, and private holdouts. Pages distinguish supplied evaluation evidence from delivery blueprints.
