"""Reconstruct a local CC2 source bundle from live GitHub data.
This helper is a recovery tool for checkouts that contain the generated CC2 board
scripts but not the original frozen `.omx/plans` and `.omx/research` bundle.
The output is intentionally marked as non-frozen so release/audit workflows do
not mistake it for the original approved plan evidence.

This local source bundle was reconstructed from live GitHub API data because the

Use this bundle to exercise `scripts/generate_cc2_board.py` locally. Do not treat
it as the original approved plan. Historical generated board artifacts record the
frozen approved-plan SHA-256 prefix separately.
