    "IB port used without source edits; Numba disk caching enabled through dispatcher.enable_caching(). Replica STRATEGY block imports IB strat_init/strat_after; no market mechanics changed.",
    "Each real strategy ran alone against repository VanillaStrategy (30 bps), run_batch(..., configs, 8). Config draw order matches MatchRunner._build_configs with rng indexed by actual seed, as in supplied IB evaluation.",
    "A diagnostic IB-only run used seed 7636000 with NOMINAL hyperparameters before training. It was excluded from confirmation statistics; confirmation uses randomized canonical configs. Thus the first real confirmation seed was previously seen under a different config; remaining 511 seeds were unseen. Supplementary strict-fresh confirmation excludes that seed and adds seed 7636512 once per arm, giving 512 unseen confirmation seeds starting at 7636001. Both requested and strictly fresh paired statistics are reported. No candidate selection used real-engine results.",
    "Real retail/arb deltas are Y volumes, not edge decomposition; holdout provides replica edge decomposition.",
    "All long work segmented with per-command 470-second timeout and scratch checkpoints. Search minutes count completed generation and subsequent monitor scoring time, excluding initial monitor setup, segment restarts and JIT warmup. Monitor points are taken at generation boundaries.",
    "Only head weight integer literals changed in Solidity; generator reproduces original IB head byte for byte at initial weights. Frozen weights rounded once to 1e6 fixed point before C and holdout. No claim of leaderboard placement."
