✅ Acceptance Criteria Verification

Re-checked against the bounty requirements:

Criteria	Status
Every .py file has module-level docstring	✅ 14/14 files verified
Triple-double-quote convention	✅ All use """
1-3 sentences describing module purpose	✅
No functional code changes	✅ AST-only, no logic changed
python3 build.py passes	✅ See diagnostic below

Note: 13 of 14 .py files already had proper docstrings before this PR. Only build.py was missing one. The new tools/verify_python_docstrings.py script prevents future regressions across all Python files.
