Beat this network's AMM entry qt1 on paradigm.xyz/puzzles/amm (board 524.9403, 8th; 7th is 525.377, +0.44; 6th 526.777). qt1 is Taylor (gtmcknight)'s solved policy (github.com/gtmcknight/amm-sim at 4812a6382311624e1506aca131ca35c378f930d9, research/solved) in Solidity: Gaussian filter plus the qm tables compressed by qm-spline. qt1 = the Solidity block of https://api.imd.fun/artifacts/8a6e303b662e1a5ea9bb47f31acedd3988ef65b3ddb66d074517aa59ad41ca40, sha256 c68887cff61180e12ba2b1ceb333edf76a830f91f63b5d775a8806fb9ec08aca; that result also holds its Python reference. Two leads, measured on Taylor's replica (links in note 1): quoting against the whole two-part posterior at a step's first trade (+0.49 over Gaussian + plain, 2 to 4 table lookups), and a cheaper lattice filter (lattice + qm is +0.49 over Gaussian + qm, but the exact lattice costs 453k gas a call).

LIMITS: deployed bytecode <= 24,576 bytes; engine afterSwap peak <= 245,000 gas and 0 OutOfGas (qt1 peaks at 208,775).

GATES: (P) Taylor's gates.py reproduces before any change; (Q) each new Python reference is scored paired against qt1's reference on Taylor's replica (choose on 60000..61023, report 10000..12047); (F) the contract's fees equal its Python reference within 0.01 bps on 50x2,000 callbacks from replica runs.

REPLICA work: plain python3 -I, any machine. ENGINE work: the Linux setup below; each strategy alone vs the 30 bps VanillaStrategy, amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8), configs per MatchRunner._build_configs; fresh seeds from 9800000 up, never reused; report paired{n,mean_diff,se,worst5} vs qt1 and amm_sim_rs.gas_stats(). No command over 8 minutes; state under scratch/. Credit Taylor in the header.

2. Merge r1 01Agent #969made 1 file
  The merge is written to artifacts/goal/roots/1/01/result.md: 63,478 bytes, under the 64,000 limit, with all 25 results accounted for and none missing or empty. I ran no simulations. Every figure is the item's own, apart from a few marked "computed in this merge".
  
  I checked every number and hash in the file against the input text; all that did not match verbatim were roundings, the brief's own figures, or the marked merge computations. Every table has consistent columns.
  
  What the merged results say:
  
  qt1's gates hold. Gate P reproduced in 21 of 25 results with no failure; the other 4 did not run it. qt1's hashes, 20,605-byte runtime and Gate F all reproduce.
  
  One candidate beats qt1 on the engine inside every limit: the two-component filter ported onto qtr2, in two independent ports. Its replica report-window score is +0.4248 (se 0.0122). That is about the size of the gap to 7th (+0.44), not clearly past it.
  
  port edge vs qt1 (se), n = 128 afterSwap peak runtime OutOfGas
  b10-port-a +0.414 (0.042) 201,916 21,102 B 0
  b10-port-b +0.439 (0.045) 213,439 21,197 B 0
  
  The best replica policy has no contract yet. Two-component filter plus pi-weighted first-trade quoting scores about +0.60 (se 0.013) on the report window in two implementations. It has no Solidity, gas, Gate F or engine result, and the available gas figures suggest the second lookup does not obviously fit.
  
  Gas headroom found: qtr2 runs about 17–18k below qt1 at the peak, binary span search saves 2,647 more, and basis edits on qt1 saved 10,507.
  
  Dead ends: max-fee quoting (−4.63), both classifier corrections, one silent cut instead of two, table-loading changes, and the coarse lattice as specified (estimated far over the gas limit).
  
  Disagreements the write-up needs to carry, all recorded in the file:
  
  Gate F wording. QMRef returns uncapped fees, so "Gate F passes" means against fees after the replica's clamp. b08-qtr2-loads took the literal reading and reports a failure on qt1 itself; six other items took the clamped reading and pass.
  
  Choose-window baseline. b01-p-choose's per-seed values (run on macOS) differ from Linux recomputations on 17 to 19 seeds; paired means move by at most about 4e-6.
  
  Port gas gap. The two ports differ by 11,523 gas at the peak for the same reference, and neither explains why.
  
  Brief figures not reproduced. The brief's 453k for the exact lattice and +0.49 for the quoting lead are not reproduced by any result here.
  
  Four results produced no usable measurement: b02-eb-a, b08-qtr2-control and b10-port-c were blocked at setup, and b09-class-size finished only 64 of 3,072 paired runs. No result in this root describes how qtr2 was made.
  
  For the eight results with sources that did not hold on re-read, their headline numbers are local runs corroborated by at least one unflagged result. I was not told which individual sources failed, so the file marks the quoted context in those results as reported rather than confirmed.
