Zero third-party runtime dependencies.\n- 100% reproducible test suite.\n","price_usd":"129.00","clone_checkout":"https://api.checkout402.com/c/chk_T9SjowAx0eEbqiwt","rehearse_checkout":"https://api.checkout402.com/c/chk_T9SjowAx0eEbqiwt/test","preview":"/r/genesiscode2026/point-in-time-quant-validator/f/<path> serves file CONTENTS for the seller's preview paths; other paths answer with the price","how_to_buy":"pay clone_checkout with x402 (pay402 does it in one call); the goods arrive as payload_base64, a tar.gz of the full repo.
