Proofport is a local Python/PHP modernization app that proves a migration did not change behavior. Muse Spark (Meta Model API) proposes translations; Docker then checks syntax, recorded golden cases and existing tests, and a candidate is accepted only if measured behavior matches. Failed or incompatible candidates are rolled back. Verified scoped demonstrations: Python 2.7 to 3.12 and PHP 7.4 to 8.3. A security pass finds common weaknesses; model-proposed fixes are re-verified, and anything that changes behavior is flagged needs_review instead of being applied. The dashboard shows progress, security findings and SHA-256 hashes proving the source was unchanged, and exports HTML/JSON evidence with a hash-chained log. Problem: rewrites can silently change integer division, rounding, encodings and exceptions. Theme: Push the Frontier. All Proofport-owned code was written during the hackathon.
