Rollout hard scores can be continuous when smoothed rewards are used. Converting the field through int() turned values like 0.75 into 0, which loses signal before scoring and serialization.
Constraint: Keep the existing RolloutResult dictionary shape unchanged.
Rejected: Clamp hard scores to 0 or 1 | contradicts existing continuous-score support in compute_score and sleep replay types.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Treat hard as numeric reward data, not only a binary label.
Tested: uv run --with pytest pytest tests/test_types.py tests/test_scoring.py -q
Tested: uv run --with ruff ruff check skillopt/types.py tests/test_types.py
Not-tested: Full benchmark rollouts.
