Gate C compares candidate frozen rounded weights and code. Both use 50 sequences of 2,000 callbacks plus initialization; quotes drive trades alternately from EVM and port.","Freezing changes only integer literals inside IB _head.

The cited decomposition harness reconstructs negative optimal arbitrage profit from step fair prices, previous final spot/fees and constant initial k; retail is the residual total edge. The diagnostic check tests paths with zero observed retail volume. Volume deltas are separately labeled.","Gas counters come from amm_sim_rs.gas_stats(), reset before each chunk and aggregated by summing counts and taking maxima. OOG includes both roles for the candidate arm. Other-arm raw counters are also included.","valid denotes completion of gates, 512-seed confirmation and gas constraints; it does not establish top-10 leaderboard placement.
