  "notes": "Group 2 of r5-cg-continue: k06-k09 accepted, k10 failed (path_violation). Cross-checks agree: gate A max fee diff 8.81e-05 bps and gate B replica CG-T = +1.9204 se 0.044 (error 0.08 of the +2.00 real reference) are identical in all four results; holdout CG over T = 1.9519 matches between k08 and k09; real CG over HA is +0.77 to +0.84 and CG over IB +0.12 to +0.18 across the four machines, consistent with the replica's over_IB of +0.18 to +0.19. Hashes of KIT, CG code/port, IB and HA were verified in every result. Substantive finding for the orchestrator: three independent long CMA-ES continuations from CG's frozen head found nothing above noise. k07 (sigma0 0.06, 512 mk/gen, 143 gens, 75 min): best monitor +0.0054 over CG, holdout +0.0057 se 0.0025, real +0.012 se 0.009 (n=512), vs IB +0.175 se 0.020 (n=1024), valid, afterSwap peak 238,448. k08 (sigma0 0.03, 1024 mk/gen, 40 gens on a 4-core host): monitor +0.0011 se 0.003, holdout +0.0021 se 0.0016, real -0.042 se 0.049 driven by one seed (8028511, -24.7) from weights that differ from CG by at most 0.017. k09 (sigma0 0.13, 128 mk/gen, 336 gens, 80 min): ES mean sat 0.002 to 0.022 below CG for the whole run and never recovered, so CG was frozen unchanged. The pilot's premise that curves were still rising does not hold for CG at this search scale: the monitor se (about 0.003 on 2,048 markets) is the size of any gain seen, and sigma 0.13 at 128 markets/gen is too noisy to even hold CG's level. k08 also shows real-engine path sensitivity: a tiny head change produced a -24.7 single-market outlier. Recommend the orchestrator not spend further items on this exact continuation; the group's consolidated answer is a null, with k07 the only candidate marginally ahead of CG (2.3 se on holdout, 1.3 se real). Decisions. Refine k06: it did not do the item. Its host was shared (load about 36 on 8 cores), the replica ran at 53-77 markets/s against the kit's 412/s reference, so no search was run, and the fallback was itself cut short: IB and HA on 392 seeds, CG on 296 with a timed-out chunk excluded rather than rerun. That is a machine shortfall, not a brief shortfall. k07, k08 and k09 answer their items with complete gates, holdout, real arms, gas and provenance; their declared shortfalls (k08 at 512 real seeds, 40 minutes) are honest and another run with the same fixed settings would almost surely reproduce the null, so no refinement. Retry k10: a path violation is a process error. The SETUP script clones amm-challenge, which carries foundry.toml, remappings.txt and lib/; if that checkout lands at the workspace root it overwrites protected configuration and the submission is rejected. Guidance tells the worker where to put the checkout and state, and carries the sibling findings on sigma and chunk sizing.",

      "guidance": "Your previous run was rejected for writing outside the item's allowed paths, not for its content. Do everything differently on layout: clone amm-challenge at 6b6921f8 into a subdirectory you create inside the item's own path or inside test/scratch/, never at the workspace root, because the checkout carries foundry.toml, remappings.txt and lib/ and a submission touching those at the root is rejected automatically. Put .venv, scratch/, setup.sh, env.sh, segment checkpoints and all real-engine chunks under that same subdirectory; run setup.sh from the checkout root there and prefix later commands with its env.sh. Deliver exactly one file, result.json under the item's path, under 40,000 bytes. Content: follow the brief as written (gates A, B, C; CMA-ES pop 32, 256 mk/gen, sigma0 0.10 capped at 0.10*0.5^(min/40), ES seed 610, train seeds from 1590000000). Siblings k07/k08/k09 ran 40-80 minutes and found nothing above monitor noise (se about 0.003 on 2,048 markets), so report se with every curve row and the monitor gain of both ES mean and generation best, run for as long as time allows (siblings reached 75-80 min), and freeze CG unchanged if nothing beats it, as the brief says. Real engine runs at 1.4-4 markets/s per arm: use chunks of at most 64 seeds per command, and if a chunk is killed by the 8-minute limit rerun it on the same seeds rather than excluding them. Give candidate and IB 1,024 seeds from 8036000 and CG/HA 512, with gas per arm."

      "guidance": "The result did not do the item: no search ran because the replica measured 53-77 markets/s on a shared host (load about 36 on 8 cores, versus the kit's 412/s reference), and the fallback was cut to 392 seeds for IB/HA and 296 for CG with a timed-out chunk excluded. Do differently: measure replica speed with the host otherwise idle and record the load average with it; siblings on quiet 8-core hosts measured 339-415 markets/s. If 200 or more, run the brief's CMA-ES as written (pop 32, 128 mk/gen, sigma0 0.13 capped at 0.13*0.5^(min/40), ES seed 606, train seeds from 1550000000) for as long as time allows after keeping 30 minutes for holdout and real, at least 40 minutes, in segments under 8 minutes with state saved under scratch/. Note sibling k09 used the same sigma and markets per generation and its ES mean sat 0.002-0.022 below CG for 336 generations; so report se on every monitor row for both ES mean and generation best, and freeze CG unchanged if nothing beats it. If speed is again under 200, complete the fallback fully instead: CG, IB and HA each on all 1,024 seeds 8020000..8021023, chunks of at most 32 seeds per command at the observed 2-4.5 s per market, and rerun any chunk the timeout kills on its same seeds rather than excluding them. Either way report paired n, mean_diff, se, worst5, retail and arb deltas and gas per arm."
