Benchmark summary
HumanEval adapted to SC#, adding an extra challenge: models must generate correct code in a custom sandboxed language while following its documentation and constraints.
Tests with multiple category tags are counted in each matching category, so category totals may exceed the report total.

| ✓ | CountBucketLoweringsModel counts total bucket lowerings needed to empty rows of wells. Provenance: HumanEval/115 (entry point max_fill). Level: Medium — per-row water sum, ceiling division by capacity, then a total; the ceiling with integer arithmetic is the trap.1 AI query

| × | EvaluateAlgebraExpressionModel writes an SC# function evaluating a small arithmetic expression with Python operator precedence. Provenance: HumanEval/160 (entry point do_algebra).

| ✓ | LexicographicMinGridPathModel writes an SC# function returning the values along the lexicographically smallest length-k grid path. Provenance: HumanEval/129 (entry point minPath).
