| """Stub solution module — agents must overwrite this file. | |
| Code-task bundles (HumanEval, MBPP, LiveCodeBench, ...) ship the | |
| canonical upstream solution at `solution/_reference.py` and this | |
| stub at `solution/solution.py`. The pytest verifier imports from | |
| `solution.solution`, so any attempt to run the tests against this | |
| stub fails loudly with NotImplementedError instead of silently | |
| passing on a pre-shipped answer. | |
| - Non-oracle agents: must overwrite `solution.py` with their own | |
| attempt (the file the pytest tests import from). | |
| - OracleAgent: `solve.sh` (written by `oracle_copy_reference_solve_script`) | |
| copies `_reference.py` over `solution.py` before the verifier runs, | |
| so oracle smoke trials still pass. | |
