Take this network's entry on paradigm.xyz/puzzles/amm to #1 (528.42; ours is qt1 at 524.94, 8th, about +3.5 short). qt1 is Taylor (gtmcknight)'s solved policy (github.com/gtmcknight/amm-sim at 4812a6382311624e1506aca131ca35c378f930d9, research/solved; README first): Gaussian filter + qm tables, about +3.8 over HA on Taylor's replica. The gap is one call: is a step's first own trade the arb or retail. The filter is wrong about 16% of the time; with the true flag the same code scores +6.98 over HA, at the leaders' level. Spend items on that call and on learned corrections to the policy under real observables, measured on Taylor's replica, which knows the true flag.

FILES: each brief names its files (links in the requester's note 1); check every sha256.

GATES: (P) Taylor's gates.py reproduces before any change; (Q) every policy is scored paired against its base reference on Taylor's replica (choose on 64000..65023, report 10000..12047), never choosing on the report seeds; (F) a contract's fees equal its Python reference within 0.01 bps on 50x2,000 replica callbacks.

REPLICA work: plain python3 -I, any machine. CONTRACTS only for a policy >= +0.5 over qt1 on the report seeds: the Linux setup below; deployed <= 24,576 bytes; engine afterSwap peak <= 245,000 and 0 OOG; each strategy alone vs the 30 bps VanillaStrategy, amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8), configs per MatchRunner._build_configs; fresh engine seeds from 9900000 up, never reused; report paired{n,mean_diff,se,worst5} vs qt1. No command over 8 minutes; state under scratch/. Credit Taylor in every header.

SETUP: clone github.com/benedictbrady/amm-challenge at 6b6921f8d463314aa7c96234e1be25a25245f704 in your workspace (never /tmp), save the script below as scratch/setup.sh, run sh scratch/setup.sh once from the checkout root, prefix later commands with . scratch/env.sh && ; on failure return blocked={step,error}.

  1. Round 1

    Agent #1299 planned it. Started 12 min after the job was posted.

    The plane refused 19 of its decisions: every decision it made was refused. The next round is told why.

    1 step
    1. Orchestrate 001Agent #1299made 1 file

      Episode 1's decisions are written and validated at artifacts/goal/episodes/001/decisions.json. The file is one JSON object in the reference shape, every filled brief is under 3,000 characters, the notes are under 8,000, and nothing else in the tree changed. The file is left untracked for the daemon to upload.

      What I found before deciding

      • The requester's note 1 with file links and sha256s does not exist yet. Every brief instead pins Taylor's repo by commit hash and makes the worker verify it with git rev-parse, which fixes every byte. The notes tell episode 2 to add sha256s if the requester supplies them.
      • I confirmed the commit exists and read the real interfaces: gates.py builds qt1 as the gaussian+qm policy, real.py's filter decides arb vs retail by a likelihood ratio with fixed constants, and replica2.run passes the true arb flag to every on_trade call. Taylor's README puts a perfect classifier at about +2.7 and the lattice filter at +4.26 over HA.
      • The challenge repo commit and the wheel in the SETUP script both answer.

      What runs now, 15 of 200 items

      • Batch gate-p, 5 items. Each reproduces gates.py first, then one diagnostic: the oracle ceiling, a split of that ceiling into belief versus quote, two knob grids, and an error anatomy of the filter.
      • Batch classify, 10 items with a 5-item canary. Each tries one way to make or hedge the arb-versus-retail call: a learned classifier, lag-1 belief smoothing, a particle filter, a routing-based retail likelihood, hedged quoting, cost-aware thresholds, a prior from the belief, the lattice and a finer lattice, a joint constant search, and a two-hypothesis belief.
      • Every item scores paired against qt1 on the same machine, chooses only on seeds 64000..65023, reports on 10000..12047, and returns a fixed JSON shape with the gates output, both seed sets' figures, misclassification rates, chosen parameters, code and notes.

      Next episode wakes when both batches settle or after 300 minutes. It should pin the gates.py output as the gate P reference, check qt1 and the oracle land near +3.8 and +6.98 over HA, rank the variants by report-seed gain, and stack the winners. Contract work waits until a policy clears +0.5 over qt1 on the report seeds.

    Wrote report.md with complete contract source and verified hashes/statistics.

    Best replica gain: +3.2067 over qt1. #1 remains unproven; the report documents the remaining engine-test shortfall.

    Wrote .imd-findings.json with {"findings":[]}.

    Hashes, headline statistics, compilation, baseline gates, and sampled policy replays matched. Full engine tests were not rerun. The report clearly discloses the unmet #1 goal and incomplete engine quota.
