  "notes": "EPISODE 3, 2026-11-10. STATE: 21/120 items used before this episode; this one spawns 10 (31/120). Trunk exists at 31ff8ed1 (reference/qt1: Strategy.sol, qmref.py, blob.bin; reference/taylor: replica2/gates/real/latt/evalpol/pol_mid; tools/setup.sh = Taylor's setup-fast.sh, exits 3 on non-Linux). Every result is public at https://api.imd.fun/artifacts/<sha256 of result.md> (checked: all eight below return 200 with matching hash).\n\nFACTS FROM RESULTS (all local measurements, none are board scores):\n- Gate P passes on every machine that ran it (Linux 3.12.3 and macOS 3.9.6), every digit. qt1-ref check 443.101741/571.454483/525.908441 reproduced everywhere.\n- qt1-ref per-seed baselines exist and are deterministic across machines: choose 60000..61023 (p-choose fa317ec1..., mean 529.971160, 0.15 s/seed) and report 10000..12047 (p-report d0307410..., mean 533.262831, sd 94.70). Pair against them by seed.\n- qt1 engine baseline (eb-b 3d9fd856..., seeds 9800128..9800255): mean 513.50, afterSwap peak 209,112, mean 138,190, 0 OOG in 1,371,375 calls; ~22 s per 32-seed chunk on that machine (55 s on another). Runtime 20,605 B.\n- Gate F harness (gf-a cff3f259..., gf-b fa3ac367...): qt1 vs qmref PASS, max 5.83e-6 bps on 70000..70049 (6.71e-6 on 70050..70099), pyrevm peak 194,051. LESSON: compare EFFECTIVE fees (reference returns clamped to [0,0.1] like replica2.clampf); raw returns differ at e.g. seed 70026 callback 1702 (0.1200 vs 0.1) by design. Every F brief must say so (qtr2-loads failed F only for this reason).\n- qtr2 (R, sha 7b99afae...) is verified against qt1's own reference: applied-fee F max 5.83e-6 bps on 70000..70049; engine paired vs qt1 on 128 seeds mean_diff 7.5e-5 (numerical noise), peak 191,821 (191,126 on another 64), runtime 19,945 B. Binary-search span patch (qtr2-spans cc5f5917..., candidate sha bbf63364...) is fee-identical: peak 189,174, runtime 19,965. qtr2-loads: no gain, empty patch. gas-dispatch on qt1: 235 gas, useless. Two engine items (eb-a, qtr2-control) were lost to macOS seats: engine briefs now open with a platform check and blocked={step,error}.\n- LEADS on the replica, paired vs qt1-ref: two-comp (latt-two-comp d3c849db..., bounded two-component filter, same single lookup as qt1) +0.4248 se 0.0122 on report 10000..12047 (n 2048) and +0.457 se 0.024 on 60000..60511; 0.17 below the exact lattice. Its 239k gas figure is a crude estimate; by operation count the worst callback costs 15 truncations vs qt1's 13 plus one phi and the moments, so on qtr2 (191.8k peak) I expect roughly 200-210k. wavg-offsets +0.277 se 0.021 and wavg-fees +0.278 se 0.022 on 60000..60511 (2 lookups per ambiguous first trade, ~5,800 such callbacks per run). max-fee -4.63: dead. Requester note 3 asks for the two-comp port on qtr2 (3 copies, gas probe first, peak <= 240k, F vs two-comp's reference, 2x512 engine) and for two-comp + weighted-average quoting on the replica.\n- Still running when this episode decided: e1-lead-latt latt-c5, latt-c10, latt-k24; e2-classifier (2 items, keys not shown in goal.json; expect them handed when settled). e1-gas-spline is cancelled (gas-basis may still land; ignore).\n\nDECISIONS (10 items):\n- e3-port-twocomp (engine, 3 copies port-a/b/c, seeds 9800704..9800831 / 9800832..9800959 / 9800960..9801087): port two-comp onto R, pyrevm gas probe on dt>=13 two-component callbacks <= 225k (qt1's engine peak 209k ran ~15k above its pyrevm peak 194k, so 225k in pyrevm leaves room under 245k), applied-fee F vs TwoComp on 70000..70049, then candidate and qt1 on 128 fresh seeds. Blob and qt1 source are reached through TC's own links. Contract delivered as a diff against R with sha256 (a full 43 KB source would not fit the result cap with the tables). The 2x512 confirm is deliberately NOT in these items: it is sharded next episode on the one frozen contract.\n- e3-twocomp-wavg (replica, combo-fees, combo-offsets): two-comp filter + weighted-average quoting using two-comp's own components; full choose and report windows vs qt1-ref and vs two-comp. Also gives an independent recomputation of two-comp on both windows (cross-machine determinism of the new reference).\n- e3-twocomp-cuts (replica, cuts-1/4/8/12): the gain curve of DUAL_CUTS against its gas cost (14+cuts truncations at the worst callback); choose window selects, report window reports.\n- e3-trunk-tools (code, 1 item): reference/qtr2 (R, spans diff, StrategySpans.sol), reference/twocomp, reference/mix, reference/CHECKS.md (edges of qmref/TwoComp/both mixes on 10000..10002, which no result has published yet), tools/check.py (Gate F, effective fees) and tools/engine.py as scripts, README seed ledger. May spend engine seeds 9801088..9801089 on a smoke test.\n- Wake when all four settle or after 150 minutes. Reads: the 10 new items, latt-c5/c10/k24, latt-two-comp, qtr2-spans, gf-a.\n\nSEED LEDGER (engine seeds, never reused, failed or unrun blocks count as spent): 9800000..9800319 episode 1; 9800320..9800703 episode 2; 9800704..9801087 e3-port-twocomp; 9801088..9801089 e3-trunk-tools smoke test. NEXT FREE ENGINE SEED = 9801090. Replica seeds repeat freely: choose 60000..61023, report 10000..12047, Gate F 70000..70049 (70050..70099 also baselined).\n\nPLAN FOR EPISODE 4:\n1. Pick the port: among copies whose F passed (max <= 0.01 bps vs TwoComp, effective fees), validator passed, runtime <= 24,576 and engine peak <= 240k with 0 OOG, take the lowest engine peak; cross-check the three copies' TwoComp edges on 10000..10002 against each other and reference/CHECKS.md. Reconstruct the chosen contract from its diff against R and record its sha256. If every copy failed, read the Problems, mend the brief (it is probably the fixed-point two-component math or the hour budget) and rerun 2 copies; if the gas probe was the blocker, port the cuts-1 variant if e3-twocomp-cuts shows it loses little.\n2. CONFIRM the chosen contract vs qt1 on two fresh disjoint 1,024-seed blocks starting at NEXT FREE (reserve 2,048 seeds), 8 items of 256 seeds (each arm alone vs Vanilla, chunks of 32, 8-16 min per item), each reporting per-seed edges, paired stats and gas_stats; the write-up combines raw differences (sample sd/sqrt n), worst five, max peak, OOG. Requester submits at >= +0.3 on 2,048 fresh seeds; 7th needs about +0.44. Also one code wave putting the chosen contract at contracts/Candidate.sol with its reference under reference/candidate/ and the three gate results.\n3. If e3-twocomp-wavg shows the gains add (COMBO-TwoComp clearly > 0 with mean_diff > 2 se on the choose window and confirmed on the report window), start its port on top of the chosen two-comp contract (2 extra lookups at ambiguous first trades: qtr2's two surfaces cost ~35-43k each in qt1's report, so check the gas probe first; ar3's 2-lookup fallback if 4 do not fit). If e3-twocomp-cuts shows a higher cut count gaining with mean_diff > 2 se, prefer it only if the probe keeps the peak <= 240k; a cut-count change is a new reference and needs its own F.\n4. Lattice-lite (latt-c5/c10/k24) and classifier results: promote only something beating two-comp on the choose window with mean_diff > 2 se and a plausible gas story; otherwise note and drop.\n5. Budget guide: ep4 ~20 items (confirm 8 + ports/reruns + code wave), ep5 ~15 (independent re-confirmation or the combo confirm), ep6 write-up: paired{n,mean_diff,se,worst5} vs qt1 on 2,048 engine seeds, gas_stats, Gate F figure, runtime size, complete code and sha256, Taylor credited. Never infer a board rank from replica or engine differences.",

Add verified inputs, verbatim, and two harness scripts.\n1. reference/qtr2/Strategy.sol = the Solidity block of R=https://api.imd.fun/artifacts/18ca35cb47390b8e8c289b240d7836804692998ad64f84ef248c43d61e199f0b (43,073 B, sha256 7b99afae570ef1627b0163fb21411f14c496b005a07c3966cc7323906dee664f; assert). reference/qtr2/spans.diff = the diff under ## Patch of SP=https://api.imd.fun/artifacts/cc5f5917337662ddf10ac494ed6593d06322b46d50fb475b99108cb9f3f15686; reference/qtr2/StrategySpans.sol = R with it applied (sha256 bbf63364ed407fc3a94ec3b4cc02223b6855b1b9c083e6e7a7566a2ba70e24b5; assert).\n2. reference/twocomp/twocomp.py = the ## Code block of https://api.imd.fun/artifacts/d3c849db2ac31e567b57e52b80b86e8c24c842e5b4125b9d75c78e3cb07115b9. reference/mix/wavg_fees.py = the ## Code block of https://api.imd.fun/artifacts/23cf289cf15eff6790cb2067a714df9d020049d2de5f3975c11857ab344cb9e4; reference/mix/wavg_offsets.py = the ## Code block of https://api.imd.fun/artifacts/6b911ad2ead493aa3d39cd55d4e95fc41ca09b4024e366655cd238825b37c6c4.\n3. reference/CHECKS.md: with python3 -I and reference/taylor/replica2.py run qmref.QMRef, TwoComp and both mix classes on reference/qt1/blob.bin for seeds 10000..10002; record each edge to 6 dp (qmref: 443.101741 / 571.454483 / 525.908441) and the commands.\n4. tools/check.py = SP's replay.py (## Scripts) as a script taking a contract path, a reference module.class, a seed range and an output path: Gate F, first 2,000 own-pool callbacks per reference-driven replica run, fresh pyrevm deployment, 245,000 gas per call, EFFECTIVE fees (reference returns clamped to [0,0.1] as replica2.clampf), JSON as the source writes it. tools/engine.py = SP's engine.py as a script taking two contracts, a seed range and an output path: each arm alone vs the 30 bps VanillaStrategy, run_batch(X, Vanilla, configs, 8), configs per MatchRunner._build_configs, JSON with per-seed edges, paired stats and gas_stats. Both run inside an amm-challenge checkout after tools/setup.sh: tools/README.md gives the exact commands. On Linux x86_64 run the setup and smoke-test both (check.py: qt1 vs qmref on seed 70000, max about 1.5e-6 bps; engine.py: qt1 vs qt1 on seeds 9801088..9801089, zero differences); otherwise py_compile both and say they were not executed.\n5. README.md: a short 'Where things are' section and the seed ledger: engine seeds 9800000..9801089 spent or reserved; next free 9801090.\nNever change reference/qt1/**, reference/taylor/** or tools/setup.sh. Result: every file written with bytes and sha256, the CHECKS values, what ran and what did not, every failure.",
