That takes this network from 107.58 to 108.38 on Paradigm's Prediction Market challenge, where first place is 109.93.\n\nThe 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\n\nThe base is a public JSON file whose \"code\" is the strategy: https://api.imd.fun/artifacts/41fa8829432f502a00c5302c0e2200b475c5c2e100a2a16b086aaab0ce62a395\nIt 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.\n\nFour seats each changed the base only in runs of one spread and proved the other spreads identical. Each file was entered on Paradigm, so its gain on those 200 runs is known exactly:\n- Spread 1, +0.775951: a larger ask once it is ahead of the rival at tick 2 under 1 cent, and front asks are not cancelled. https://api.imd.fun/artifacts/08e3cde58c80ef5d44a5af6a896eeeef75abff9ff749e01d2ee329f1c68d2d60\n- Spread 2, +0.065331: scales the one-cent stock target by each run's own flow. https://api.imd.fun/artifacts/90459c5fffa37760b92c6a3ee93523240927484a7c8fa36b5d12b55a37c08733\n- Spread 3, +0.164311: keeps a front ask at the rival's tick only while 20 dollars of it are ahead. https://api.imd.fun/artifacts/adc67b24de94a37b17f0c930c42890ffd1286d8a83c1533e020a1eb7bd6aad43\n- Spread 4, +0.574129: estimates each run's retail flow from its own fills and sizes asks and stock from it. https://api.imd.fun/artifacts/c80c33382f9c458ab6286dbc11fa761100a7e156dad7f3c12d74040b7c76578f\n\nA run has one spread. So a file that acts like each of the four in runs of its own spread scores 106.804593 + 0.775951 + 0.065331 + 0.164311 + 0.574129 = 108.384315 on Paradigm, if the stack is exact: in every run it must give the very result its source file gives.\n\nSpread 2's change is the smallest, so it may be beaten. Three other files of this network carry changes that act in every spread, each built on the base's parent (https://api.imd.fun/artifacts/40497298132dcc0ccc9f4c0672031c7eaae00ddcf8cf24983db989feeb3c5ca0):\n- Demand, +0.62 on Paradigm's runs: https://api.imd.fun/artifacts/8b4ad631c15180565229a8ef483520e09c238374bbfe3254fa1e9e0d8bdfb3a0\n- Cash, +0.43 on Paradigm's runs: https://api.imd.fun/artifacts/a261c9ded9200dd29189d624562aff18826e59e8fa7220b4cebcd9e7ea1aa330\n- Demand with floors, +0.55 on unseen runs, not entered: https://api.imd.fun/artifacts/db492ed5ea693781491dd7ef27a59d076aa1860b94bea08bd0e134b608e0d93b\n\nThe network's operator enters files on Paradigm by hand: nothing is entered from a task, so do not look for a key.

It took 31 s, so I did not halve any run counts.\n- **How it was built:** I started from the spread-4 file and kept its code as written. Its own sum loop rounds differently from the base's under Python 3.12, so rewriting it would have broken exactness. To that I added:\n  - spread 1's larger ask at tick 2 and its rule against cancelling front asks;\n  - spread 3's rule of keeping a front ask only while $20 of it is ahead.\n\n  Each one acts only in its own spread. The spread 1, 2 and 3 files also rewrite a loop, but only for speed with the same arithmetic, so I left that out.\n- **Exactness:** I compared every field of every run, 300 runs per spread on seeds from 60000:\n  - The exact stack, with spread 2's flow change, matched all four source files.\n  - The final file matched the spread 1, 3 and 4 files.\n  - In spread 2 the final file matched Cash's own file on all 1,987 spread-2 seeds. Cash is built on the parent, which behaves like the base in spread 2.\n- **The swap:** Cash's three changes act only when `self.s == 2`.

Enumerating the delivered artifacts yields only artifacts/goal/writeup/report.md and its .imd/reads/artifacts/report copy, with no Python strategy or result JSON. Expected: the operator can obtain the recommended code by opening the delivered strategy or its report link. Actual: the entry recommendation ends at a missing file and two hashes. Independently fetching the public API URL using the input digest returns JSON with a code field whose SHA-256 is 1d2db2a895bf0f9e427f6f15f6be20734e4e11643200d195bcb154c7534ee581, confirming a concrete working link can repair the delivery.","severity":"medium","snippet":"- **B:** [item-stack-b](../../../.imd/reads/artifacts/item-stack-b), logical source `artifacts/goal/items/stack-b/result.json`; input SHA-256 `ceae4e41f3555400ea8dd71cfcabdf3698613142560717eca64acc9e029d0c3d`; strategy-code SHA-256 `1d2db2a895bf0f9e427f6f15f6be20734e4e11643200d195bcb154c7534ee581`.","title":"Link the recommended strategy to its public artifact"}],"hash":"8a351bf348903d0a42ec2ff0f478617740523ceadfe67ff585af478439a863e0","nodeId":"b06e1123-244d-4597-9c13-91f3b93ebe89","outcome":"completed","summary":"Recorded one medium finding in [.imd-findings.json](/home/seat/.identitymd/work/146ea942-7ad5-4ea4-baf5-cf88907a2b2e/b06e1123-244d-4597-9c13-91f3b93ebe89/.imd-findings.json): the recommended strategy link points to a missing local file.\n\nScore arithmetic checked out.
