Trunk 4eb3e985 (contracts/Candidate.sol = TC-A sha b87234c89e094f4955578417c1266129b0f96e6dfda68e3fb8866e00eeda71a2, runtime 21,102 B; reference/candidate/GATES.md; reference/combo/{combo.py,combo_fees.py,twocomp.py,README.md}; reference/qt1, qtr2, twocomp, mix; tools/check.py, engine.py, setup.sh; README seed ledger). Every result is public at https://api.imdnotdead.fun/artifacts/<sha256 of result.md> (cp-a 4cc25dfb..., cp-b 2d2f954f..., gate-choose 1446141a... checked 200). Episode 6 is the LAST episode (maxEpisodes 6).\n\nFACTS FROM EPISODE-4 RESULTS (local measurements, not board scores):\n- TC-A CONFIRMED. 13 of 16 shards landed, each n=128, TC-A minus qt1 (mean, se): a1s1 9801090.. +0.4621 0.0480; a1s2 +0.4413 0.0534; a1s3 +0.5007 0.0502; a1s4 +0.3864 0.0481; a2s1 +0.5363 0.0482; a2s2 +0.4336 0.0470; a2s3 +0.3972 0.0423; b1s1 9802114.. +0.4403 0.0477; b1s2 +0.3521 0.0473; b1s3 +0.4334 0.0517; b1s4 +0.5069 0.0503; b2s3 +0.4208 0.0635; b2s4 +0.4491 0.0460. Combined n=1,664: mean_diff +0.443, se about 0.014 (pooled from shard sds; the write-up should recompute from the per-seed tables). Every shard: TC-A afterSwap peak <= 211,164 (a1s1), typically 204-209k; 0 OOG, 0 reverts; runtime 21,102 B. TC-A passes the requester's +0.3 submission threshold and sits at the +0.44 7th-place estimate. Still running since episode 4: a2s4 (9801986..9802113), b2s1 (9802626..9802753), b2s2 (9802754..9802881); read them next episode and add them if they land.\n- COMBO PORT IS GAS-BLOCKED at every gate: cp-a (port sha e4c64fa8..., runtime 21,853, cheaper port) mixed dt=1 peak 216,964 pyrevm, dt=3 221,425, dt 7-9 238,399, OOG at dt=11; cp-b (sha 9a19e74a..., runtime 21,743) dt=1 222,641, 9 OOG at dt>=10 over 10 seeds. Budget was 215k pyrevm (engine peak runs 15-24k above pyrevm). Neither ran F or the engine. cp-c never landed.\n- GATE STUDY (gate-choose, replica, choose window n=1024, qt1-ref recomputed locally): GATE=2 best: +0.6457 se 0.0192 vs qt1, +0.2002 se 0.0145 vs TwoComp, +0.0078 se 0.0077 vs ungated; GATE 1/3/4/6/9/ungated all +0.636..+0.641 vs qt1. Mixed quotes per run 5,285 at GATE 2 (579 gated away), 5,861 ungated. So the gate costs nothing: the whole problem is the dt<=2 mixed path (~217k) which must come down to <= 205k pyrevm. gate-report (report window) still running.\n- Requester note 4 asks episode 5 for a gas diet on ComboG, 3-4 items: (a) arb component on the sd-0 slice only, (b) qtr2-spans load trims, (c) DUAL_CUTS=1 plus a lower silent-step cap with its replica cost, (d) average fees instead of offsets if it saves exponentials. Target every bucket <= 205,000 pyrevm, 0 OOG, then F and 2x512 engine; episode 6 confirms the best on 2,048 seeds. I did not spawn (d): combo-fees converts each branch (4 exps) where offsets converts once (2 exps), so it cannot save exponentials; (a) is fee-identical (sd=0 gives k=0, tt=0, so the level k+1 evaluation is multiplied by zero), (b) is fee-identical, (c) changes the reference and needs its own Q and F.\n\nDECISIONS (9 items):\n- e5-gas-diet (pyrevm only, no engine seeds; 4 items, each a frozen source + per-dt-bucket pyrevm probe on 70000..70004 with recovery calls + GATE choice at 205k + F vs its ComboG reference on 70000..70049): gd-a = (a) only; gd-ab-1 and gd-ab-2 = (a)+(b)+any further fee-identical trims, two independent copies; gd-abc = (a)+(b)+(c) with DUAL_CUTS=1 and cap 9, F against a modified twocomp copy. All start from cp-a's port diff applied to K/contracts/Candidate.sol. If no gate fits, the item still freezes GATE=1 and reports the measured saving. The engine gas of a passing copy comes from its 2,048-seed confirmation (engine peak has run 15-24k above the pyrevm F peak: qt1 +14.7k, TC-A +23.6k).\n- e5-cuts-q (replica, cq-choose 60000..61023, cq-report 10000..12047): ComboG(GATE=2) variants V1 cuts1/cap12, V2 cuts1/cap9, V3 cuts1/cap6, V4 cuts2/cap9 vs qt1-ref, TwoComp and the baseline ComboG(2) cuts2/cap12; 10000..10002 edges per variant for matching gd-abc's reference.\n- e5-confirm-fill (engine, 3 shards f1/f2/f3 of 128 fresh seeds 9803188..9803315 / 9803316..9803443 / 9803444..9803571): replacements for the three unlanded TC-A shards so n reaches 2,048 even if they never land; if they do land too, combine everything (all seeds are fresh and disjoint; pre-registered, none excluded).\n- Cancelled: e1-lead-latt, e2-classifier (dead leads running since episode 1-2), e4-combo-port (cp-c cannot change the gas verdict).\n- Wake when the three new batches settle or after 150 minutes.\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 TC-A block A; 9802114..9803137 TC-A block B; 9803138..9803185 e4-combo-port; 9803186..9803187 e4 smoke; 9803188..9803571 e5-confirm-fill. NEXT FREE ENGINE SEED = 9803572. Replica seeds repeat freely (choose 60000..61023, report 10000..12047, F 70000..70049).\n\nPLAN FOR EPISODE 6 (the last one):\n1. TC-A is the deliverable regardless: complete code = K/contracts/Candidate.sol at trunk 4eb3e985 (sha b87234c8..., runtime 21,102 B, reference reference/twocomp/twocomp.py DUAL_CUTS=2, F max 6.30e-6 bps on 100,000 callbacks, engine peak <= 211,164, 0 OOG). Combine every landed shard (13 + up to 6) per seed: n, mean_diff, se = sample sd/sqrt(n), worst five, max peak, OOG. Request the shard results you need in `read` (30 cap) so the write-up has the per-seed tables; the per-shard figures above are enough to cite otherwise.\n2. Gas diet: a copy PASSES when every probe bucket <= 205,000 pyrevm at its GATE (and the F run's pyrevm peak <= 215,000 with 0 OOG), F max <= 0.01 bps vs its reference, validator OK, runtime <= 24,576. Prefer gd-ab copies (fee-identical to ComboG, whose replica Q is gate-choose: +0.6457 se 0.0192 vs qt1 at GATE 2; gate-report gives the report window). gd-abc needs e5-cuts-q's V2 figure (cuts1/cap9) as its Q and its 10000..10002 edges must match the item's reference. If one passes, spawn its 2,048-seed confirmation vs qt1 (16 shards of 128 from NEXT FREE, same brief as e5-confirm-fill with the new source sha/runtime; the source must be reconstructible from the diet result's diff against K/contracts/Candidate.sol) and a code wave freezing it at contracts/Combo.sol with reference/combo/combog.py (exact GATE) and its gate record. Since episode 6 is the last, say in the notes that the write-up reports TC-A as the confirmed contract and the COMBO candidate with whatever of its confirmation landed (the replica Q and the pyrevm gas figures if the 2,048 block is incomplete); never present an unconfirmed candidate as the submission.\n3. If no copy fits 205k: report the measured savings per diet step and finish with TC-A (set finish=true only if nothing else worth running is in flight). The remaining lever would be the 2-lookup path at dt=1 itself; nothing cheaper than one extra lookup is known.\n4. Write-up contents: paired {n, mean_diff, se, worst5} vs qt1 on the fresh engine seeds per contract, gas_stats peak/mean/OOG, the Gate F figure, runtime size, complete code with sha256 (trunk file + raw URL), Taylor credited in the header; replica Q figures labelled as replica, never a board rank; the requester submits.",

Apply the diet to P's port (tables, spline evaluation, rounding unchanged; no assembly, no new storage); measure each step's saving on seed 70000's mixed dt=1 peak. 2. Probe the final source ungated on replica seeds 70000..70004 at 245,000 gas per callback (on OOG redo it with a 1,000,000-gas recovery call, counted failed); per bucket {1,2,3,4,5-6,7-9,10-12,>=13}: mixed callbacks, peak, OOG; plus the non-mixed peak. 3. GATE = largest of {1,2,3,4,6,9,ungated} with every mixed bucket dt<=GATE and the non-mixed peak <= 205,000; if none, GATE=1 and say so under Problems. 4. Set GATE in the contract and as combog.py's class default; sha256, runtime bytes, `amm-match validate`. 5. F: `python check.py CAND.sol combog.ComboG 70000 70050 out.json`, pass = max <= 0.01 bps. Result: platform, setup, Gate P; each diet step's saving; the bucket table; GATE and why; the frozen source as a unified diff against K/contracts/Candidate.sol, its sha256 and runtime bytes; the exact combog.py and, if fees changed, its edges on 10000..10002; F {max_bps, seed, callback, pyrevm peak, oog}; commands; Problems.
