{ "notes": "EPISODE 4, 2026-11-10. STATE: 31/120 items used before this episode; it spawns 22 (53/120). Trunk c1c9a349 (reference/qt1, reference/qtr2 incl. spans patch, reference/twocomp, reference/mix, tools/check.py, tools/engine.py, tools/setup.sh, tools/README.md, reference/CHECKS.md). Every result is public at https://api.imd.fun/artifacts/.\n\nFACTS FROM EPISODE-3 RESULTS (local measurements, not board scores):\n- TWO-COMP PORT PASSED. port-a (A=ebab165b...): TC-A = qtr2 (R) + two-component filter in R's four words, candidate sha256 b87234c89e094f4955578417c1266129b0f96e6dfda68e3fb8866e00eeda71a2, runtime 21,102 B, validator OK; Gate P OK; Q vs qt1-ref choose +0.4454 se 0.0176 (n 1024), report +0.4248 se 0.0122 (n 2048) = TC's figures exactly; gas probe 177,611 pyrevm on dt>=13 two-component callbacks; F 100,000 callbacks max 6.30e-6 bps (effective fees) vs twocomp.TwoComp; engine vs qt1 seeds 9800704..9800831: +0.4145 se 0.0423, peak 201,916, mean 131,111, 0 OOG. port-b (5f152829...): same reference with two extra storage words (slots 4,5): +0.4385 se 0.0452 on 9800832..9800959, peak 213,439, runtime 21,197. port-c was a macOS seat (blocked). Combined 256 fresh engine seeds TC-A minus qt1 about +0.43 se 0.031. Engine peak runs 15-24k above the pyrevm F peak (qt1 +14.7k, TC-A +23.6k): budget pyrevm <= 215k for engine <= 240k.\n- COMBO (two-comp filter + weighted-average quoting at ambiguous first trades, TwoComp's own components as branches): the gains ADD. combo-offsets (C=d360bea6...): vs qt1-ref choose +0.6379 se 0.0196, report +0.5974 se 0.0134; vs TwoComp +0.1925 / +0.1726; state bit-identical to TwoComp (only the quote changes); 10000..10002 edges 444.195330/572.172682/526.274760; about 5,870 mixed-quote callbacks per run, 2 offset lookups each. combo-fees (9169c2f7...) is equal within 0.002. Chosen rule for the port: offsets (one fee conversion). Open problem = gas: the mixed quote on a long silent gap would exceed the limit, so the port carries a dt gate (mixed quote only when dt <= GATE, else TwoComp's single lookup). Ambiguous first trades with dt>=4 are ~3% of the mixed quotes, dt>=7 ~0.1%, so a gate at 3-6 should cost almost nothing; e4-combo-gate measures it.\n- DUAL_CUTS 1/4/8/12 are all within 1-2 se of 0 against cuts=2 on both windows: keep 2. class-age classifier: report +0.008 se 0.007: dead. latt-c5/c10/k24 and the second classifier item are still 'running' since episode 1-2; not waited on.\n- qt1-ref choose-window baseline (PC, fa317ec1...) differs on 17 of 1024 seeds (<=0.048) from Linux recomputation (PC ran on macOS Python 3.9.6); PR (report) reproduces on all 2048. Pairings change by 3e-6. Briefs now say: recompute qt1-ref locally.\n\nDECISIONS (22 items):\n- e4-confirm-a1/a2/b1/b2 (engine, 16 shards of 128 seeds): TC-A vs qt1 on two fresh disjoint 1,024-seed blocks, A = 9801090..9802113, B = 9802114..9803137, via K/tools/engine.py in chunks of 16. TC-A is reconstructed from A's diff against R (sha check). Requester note 1(d) and the +0.3 submission threshold on 2,048 fresh seeds.\n- e4-combo-port (engine, 3 copies cp-a/b/c, 16 seeds each: 9803138..9803153 / 9803154..9803169 / 9803170..9803185): COMBO-offsets on TC-A with GATE chosen by a pyrevm probe (largest of 1,2,3,4,6,9,ungated with every bucket dt<=GATE <= 215k), F vs ComboG(GATE) effective fees on 70000..70049, then a 16-seed engine gas check vs qt1 (the edge comes from the 2,048-seed confirm next episode). Copies may pick different GATEs; the replica item covers every GATE in the set.\n- e4-combo-gate (replica, gate-choose 60000..61023, gate-report 10000..12047): ComboG for GATE in {1,2,3,4,6,9,ungated} paired vs qt1-ref, TwoComp and ungated Combo, with mixed/gated-away counts.\n- e4-trunk-candidate (code, 1 item): contracts/Candidate.sol = TC-A + candidate.diff, reference/candidate/GATES.md, reference/combo/*, README seed ledger; smoke seeds 9803186..9803187.\n- Wake when all seven settle or after 150 minutes. Reads: the 22 new items, port-a, port-b, combo-offsets, tools, and latt-c5/c10/k24 if they ever land.\n\nSEED LEDGER (engine seeds, never reused; failed, blocked or unrun blocks count as spent): 9800000..9800319 ep1; 9800320..9800703 ep2; 9800704..9801089 ep3; 9801090..9802113 confirm block A; 9802114..9803137 confirm block B; 9803138..9803185 e4-combo-port; 9803186..9803187 e4-trunk-candidate smoke. NEXT FREE ENGINE SEED = 9803188. A confirm shard that did not run (macOS seat, setup failure) is NOT rerun on its seeds: replace it with a fresh 128-seed shard from NEXT FREE in episode 5 so that n reaches 2,048. Replica seeds repeat freely (choose 60000..61023, report 10000..12047, F 70000..70049).\n\nPLAN FOR EPISODE 5:\n1. TC-A confirmation: combine the 16 shards' per-seed diffs (raw differences, sample sd/sqrt(n), worst five, max peak, OOG) per block and overall. If n >= 2,048 and mean_diff >= +0.3 with the peak <= 245k and 0 OOG, TC-A is submittable as is: say so in the notes and keep its complete code (contracts/Candidate.sol, sha b87234c89e094f4955578417c1266129b0f96e6dfda68e3fb8866e00eeda71a2) and gate record ready for the write-up. Missing shards: spawn replacements (fresh seeds) in one small batch.\n2. COMBO: among cp-a/b/c take copies with validator OK, F max <= 0.01 bps, runtime <= 24,576, engine peak <= 240k, 0 OOG; prefer the largest GATE, then the lowest peak. Its replica Q is the e4-combo-gate figure for that GATE (choose window selects, report window reports; demand ComboG minus TwoComp > 2 se on both). If one passes: a code wave putting it at contracts/Combo.sol with reference/combo/combog.py (exact GATE) and its gate record, and CONFIRM it vs qt1 on two fresh 1,024-seed blocks from NEXT FREE (16 shards of 128, same brief as e4-confirm with the new sha/runtime); optionally 4 shards of COMBO vs TC-A paired on the same seeds is NOT needed (both are paired to qt1 on shared seeds: compare per seed). If every copy failed on gas even at GATE=1, COMBO is dead at this gas budget: write up TC-A; the only other lever is the spans patch (-2.6k) which does not change that.\n3. If the TC-A confirm comes in under +0.3 (unlikely: 256 seeds say +0.43 se 0.031), do not tune on the confirm blocks; report it honestly and let the COMBO result decide.\n4. Budget: 53 used after this episode; ep5 up to ~25 (16 COMBO confirm + code wave + replacements), ep6 = write-up (finish=true): paired{n, mean_diff, se, worst5} vs qt1 on 2,048 fresh engine seeds per contract, gas_stats peak/mean/OOG, Gate F figure, runtime size, complete code with sha256, Taylor credited; never infer a board rank from replica or engine differences; the requester submits.\n5. Reconstruction note for any item: TC-A = R + A's diff (patch -p1), sha b87234c89e094f4955578417c1266129b0f96e6dfda68e3fb8866e00eeda71a2; after e4-trunk-candidate merges it is contracts/Candidate.sol in the trunk (use the merge commit's raw URL, not c1c9a349).", "spawn": [ { "name": "e4-confirm-a1", "mode": "research", "brief": "Goal: beat IMD's AMM entry qt1 (Taylor gtmcknight's Gaussian filter + qm-spline tables); credit Taylor (gtmcknight) in headers.
