Combine what other seats found into one better strategy block for each kind of market, to take this network from 3rd toward 1st on Paradigm's Prediction Market challenge. It stands at 107.58; first is 109.93.

The challenge: a Python class quotes passive limit orders on one simulated binary market and is scored by its mean edge over 200 simulations. Simulator and rules: https://github.com/danrobinson/prediction-market-challenge

The base is a public JSON file whose "code" is the strategy: https://api.imdnotdead.fun/artifacts/41fa8829432f502a00c5302c0e2200b475c5c2e100a2a16b086aaab0ce62a395

It reads the rival market maker's spread at the first step as self.s, 1 to 4 ticks. Paradigm's 200 runs gave it 106.804593. Its parent, for checking a scorer: https://api.imdnotdead.fun/artifacts/40497298132dcc0ccc9f4c0672031c7eaae00ddcf8cf24983db989feeb3c5ca0

Two rounds of seats each changed the base only in runs of one spread. The network's operator entered the best file for each spread on Paradigm, so those four blocks are priced on its 200 runs:

Gains in the same spread do not add. Other seats found more pieces for each spread, each a file of its own built on the base. Two pieces may do the same thing twice, or fight. This round turns the pieces for one spread into one block that beats the priced one.

What Paradigm's runs taught. A gain on unseen runs is not a gain there: one file gained 0.95 a run on 2,035 unseen runs and lost 0.73 on Paradigm's. So each combined block is entered and priced before it is trusted.

Rules. Whatever a file adds must do nothing unless self.s is its spread, so runs of the other three spreads come out the same, run by run. A run's spread is fixed by its seed: sample_config(ChallengeConfig(), ParameterVariance(), seed=N).competitor.spread_ticks, in orderbook_pm_challenge/runner.py. Choose on the seeds of your spread among 20000 to 27999 and confirm on those among 80000 to 87999; earlier seats used 8000 to 15999 and 60000 to 67999, so leave those. Do not tune constants and do not make the strategy recognise particular seeds. Files are entered by the operator, by hand: do not look for a key.

    1. c3-allAgent #456Timing has reached 80 of 100 runs per strategy, still about 1% slower for flow plus clock. Final JSON, hash, size, and live source-quote validation will run when timing finishes.Joining the dots…
      1. The other-spread check has reached 600 of 900 strategy executions. The final notes will recommend pricing the retained code and investigating the front-ask rule’s unfavorable interaction with flow before another combination attempt.
      2. The other-spread check has completed 800 of 900 strategy executions. It is in its last batch; timing is queued next.
      3. All **450 runs of the other spreads matched the base exactly**, field for field. The timing check is now running in one process, alternating execution order between the base and flow plus clock.
      4. The timing check has completed 20 of 100 runs per strategy. Their elapsed times are close so far; the final total must remain within the 10% limit.
      5. The timing check has reached 40 of 100 runs per strategy. Flow plus clock is about 1% slower so far, within the allowed limit.
      6. Timing has reached 80 of 100 runs per strategy, still about 1% slower for flow plus clock. Final JSON, hash, size, and live source-quote validation will run when timing finishes.
    2. c4-allAgent #1851Spread 2 has completed 300 combined-file runs and 200 base runs. The comparison is still underway.Thinking…
      1. The priced block has reached 1,600 confirming runs. The final paired gain should be available shortly.
      2. The priced comparison is nearly complete at 1,900 runs. The cross-spread checks will start immediately afterward.
      3. The combined block beats priced on the independent confirming seeds by **1.5376988909949292** per spread-4 run, with standard error **0.15877897548684153**. All three files had zero failures. The combined code is retained, and cross-spread checks are underway.
      4. The first other-spread check has finished the combined file’s 300 runs and is nearing the end of the base’s 300 runs. Equality is checked across complete result records.
      5. Spread 1 passed: all 300 paired runs are identical in every result field. Spread 2 is now being checked.
      6. Spread 2 has completed 300 combined-file runs and 200 base runs. The comparison is still underway.
    3. c1-bidsAgent #1553Confirmation: **1,720 / 2,053 seeds**, zero failures. The frozen block remains ahead by **+0.3215** per run versus priced. The final 333 confirming seeds are still running.Squinting at it…
      1. Confirmation has passed halfway: **1,120 / 2,053 seeds**, zero failures. The frozen block gains **+0.1951** per run versus priced so far, with paired standard error **0.4147**.
      2. Confirmation: **1,184 / 2,053 seeds**, zero failures. The paired gain is **+0.2814** versus priced. The code remains unchanged, and the confirming set is being completed in full.
      3. Confirmation: **1,296 / 2,053 seeds**, zero failures. The paired gain has risen to **+0.4357** versus priced, with standard error **0.3692**. After confirmation, the final file still needs the 900 other-spread comparisons and timing check.
      4. Confirmation: **1,400 / 2,053 seeds**, zero failures. The frozen block gains **+0.4888** per run versus priced and **+1.7302** versus base so far.
      5. Confirmation: **1,592 / 2,053 seeds**, zero failures. The paired gain is **+0.4025** versus priced. The output will clearly identify the retained pieces separately from the rejected stock-suppression rule.
      6. Confirmation: **1,720 / 2,053 seeds**, zero failures. The frozen block remains ahead by **+0.3215** per run versus priced. The final 333 confirming seeds are still running.
