"""Place openai/math's reference proof as a submission (used by the oracle's solve.sh).
Standalone: the adapter copies this file into every task's solution/ directory.
reference.py <openai-math lean dir> <closure.txt> <solution module> <workspace>
Each module in closure.txt (``OAI.A.B``) is copied from ``<lean>/OAI/A/B.lean`` to
``<workspace>/Submission/OAI/A/B.lean`` with ``import OAI.X`` rewritten to
``import Submission.OAI.X``; ``Submission.lean`` imports the solution module. Declaration names
are namespaces, not module paths, so the theorems keep the names the challenge expects.
