# C423 alternate verification provenance

The root agent wrote and executed ROOT_SECOND_METHOD.py separately from the nine research calculations. It imports none of their calculation modules. The alternative uses direct table-cell baselines and an offset polynomial for all528 records, unordered coordinate/context enumeration, independently typed Noah/Flood-to-Shem joins for the six paired translations, integer affine coefficients, all373×373 pivot pairs, prime-factor exponents and quarter-integer components. The main calculation data are compared against independently recomputed outputs; this is not an independent-agent review.

All595 checks passed. The result was reproduced byte-for-byte using the final C423 frozen sources. Portable command: `python3 evidence/ROOT_SECOND_METHOD.py --sources sources --out secondary_replay` from the C423 packet root. Compare ROOT_SECOND_METHOD_RESULTS.json with the copy under evidence/.

The sealed-packet integrity audit separately re-extracted and replayed C414–C422 before C423 synthesis. After C423 publication, the final packet will receive the same audit and the recovery packages will record all ten results. C424 was not executed. Check counts express verification inventory, not independent witnesses or historical likelihood.
