(1e4c44b4...). IB port and replica used as given, nothing rebuilt; the differential harness is the RS2 port artifact differential_test_source adapted to take a .sol and a TH vector.","J2 port = IB port with J2 weights in the 178 head entries, J2 values in the 38 named constant entries and the 3 anchor entries (ANCHOR_CAP 701, ANCHOR_LIN, ANCHOR_QUAD); regenerating J2 Solidity from J2 params with this item code generator reproduces J2 code byte for byte (self-check), so the freeze path was verified even though it was not needed.","SPEED first: at 04:13 local the 512-market timing gave at most 226 markets/s (1/2/3/4/8/18 processes: 91.7, 187.8, 219.3, 226.4, 212.1, 196.1 markets/s; serial 84.3), below the 500 markets/s threshold, so the search was skipped per the brief.

Worst seed 8524059 (-7.34). J2 gas: afterSwap peak 237043 <= 245000, 0 OOG, 0 other failures over 11.08M afterSwap calls; IB peak on the same seeds in gas.IB.","The real engine exposes edges, pnl, retail_volume_y and arb_volume_y but no retail/arb edge split, so real retail and arb deltas are VOLUME (Y) deltas; replica retail and arb EDGE deltas for J2 minus IB are reported next to them.","Holdout and monitor reproduce the J2 item numbers (replica deterministic): monitor J2 over T 2.3098 on 30000000..30002047; holdout over_T 2.2744, over_base 0.5054. Those seeds were evaluated once in this item.","Gate C: nothing new was frozen in real-only mode, so the frozen Solidity is J2 code and the frozen port is J2 port; the gate A measurement (max 0.000134 bps over 100,050 callbacks) covers it.","T was not run on the real engine in this item (the brief asks for candidate and IB). Candidate is about +1.2 over HA by the J2 item real figures; no leaderboard placement is claimed. The search seeds 1368000000.. were not consumed; a later worker on a machine with more CPU can start the planned search from J2 unchanged.","No command ran over 8 minutes: real runs were segmented into resumable 64-seed chunks (5-6 chunks per command) with gas_stats_reset per segment and the per-segment gas snapshots aggregated (max of peaks, sum of counts)."]}
