 "notes": "Credit Taylor (gtmcknight): replica, filters, dynamic program and qm tables, github.com/gtmcknight/amm-sim @4812a6382311624e1506aca131ca35c378f930d9, research/solved, README first.\n\nEPISODE 10, THE LAST (2026-11-10, 10:45Z): finish=true. On entry 87/200 items, 0 failed, 0 refused, no requester note after note 7. All 30 input sha256 equal the task's list. Pooled figures below were recomputed here from the results' per-seed rows or block statistics; the bundles of rp-1..3 and lb-4 were decoded as data (hashes match); no worker code was run. Nothing spawned: no episode is left to read a result. Cancelled e08-refit-stack (running since episode 8; rq and rp answer it). 113 items unspent.\n\nOUTCOME. #1 is NOT reached. The goal has a contract that passes every gate and is worth about +3.2 over qt1 locally; #1 needs about +3.5 to +3.6. qt1 524.94 + 3.2 is about 528.1 (528.0 by the 0.97 ratio): level with 5th (528.099 on note 2's board), about 0.3 short of #1 (528.415). Local arithmetic, not a board score.\n\nDELIVERABLE: StrategyR.sol, sha256 c54d8d48d4a62ac655024ffa8b0e808e45d9809c9612fb614895aab10aee3491, 49,905 source bytes, runtime 22,953 bytes (sha256 23f8715372e4edf06692c342e082521ef1e601575616f1042b458eb6118e954e), solc 0.8.24 viaIR, optimizer 200 runs, EVM paris. It is lb-4's LEAN contract (TC-A two-component filter + lean wad tell) with only the QMS1 coefficient words replaced by visit-refit's blob (sha256 ca5a606d074224ccc72fb4999c1d01a677ba00440ba39df2f99eba4913a72e1d). Three seats (rp-1, rp-2, rp-3) built it to the same bytes. Checked here: the three bundled files are identical and differ from lb-4's Strategy.sol in 242 of 720 lines, each a coefficient word; no inline assembly, no external call. It is in each rp result at bundle.data (base64 tar.xz, scratch/StrategyR.sol). Rebuild: tca-path's source_bundle (base85 tar.xz) into an empty directory, lb-4's bundle over it, delete the four files lb-4's NOTES.md names, run materialize.py, then an rp bundle. Say two stale things in the file: its header comment names the original blob (3ac7cb88...) and getName returns \"TaylorTCALeanTell\", as LEAN's.\nFALLBACK, confirmed on more seeds: lb-4's Strategy.sol, sha256 a243bb3570545fb614d8995ced61e811db8e075af68e636add20eaf8fbaeebfb, runtime 22,946 bytes (sha256 dab7d69ddb7a172624b37828021941904406326442fb11f750a727e16707d017).\n\nGATES for StrategyR (R). Q = replica 10000..12047, paired. E = each strategy alone against the 30 bps VanillaStrategy on the release wheel, fresh seeds.\n- P: gates.py reproduces the README rows in every item.\n- Q (rq-1..rq-4 joined by seed, n 2048): R-qt1 +3.2067 se .0224, min -1.312 (seed 11062), 3 seeds below 0, none below -2. LEAN-qt1 +3.1599 se .0222. R-LEAN +0.0468 se .0036. R was chosen over LEAN on choose seeds only, four blocks of 256, each decision written before its report block: +0.052, +0.037, +0.060, +0.061; pooled n 1024 +0.0526 se .0050.\n- T: Solidity label = reference label on 350,950 first trades of replica seeds 74200..74249, 0 mismatches (same seeds in all three rp items: one measurement).\n- F: 100,000 callbacks (50 x 2,000), largest fee error 4.84e-7 bps.\n- G: 22,953 bytes; engine afterSwap peak 222,787 gas, 0 out-of-gas, 0 other failures, in 8,578,549 callbacks over 792 seeds (qt1 209,287).\n- E, n 256 each (9993100..355, 9994100..355, 9995100..355): R-qt1 +3.1292 se .0590, +3.2262 se .0621, +3.1282 se .0634; pooled n 768 +3.1612 se .0355; worst5 -0.388 (9995148), +0.163 (9993174), +0.627 (9995355), +0.785 (9995311), +0.805 (9995268). R-LEAN on the same seeds +0.0523, +0.0484, +0.0493; pooled +0.0500 se .0059. LEAN-qt1 there +3.1112 se .0354.\n\nCONFIRMATION of lb-4 by four other seats (e09-confirm; source and runtime hashes equal in all; nothing repaired).\n- T on 74300..74499: 1,396,492 first trades, 0 mismatches. F: 4 x 100,000 callbacks, largest 4.82e-7 bps.\n- E: cf-1 9990000..9990511 +3.2131 se .0434; cf-2 9990512..9991023 +3.1947 se .0398; cf-3 9991024..9991343 (n 320; 192 not run, for time) +3.1303 se .0537; cf-4 9991536..9992047 +3.2230 se .0439. Pooled n 1856: +3.1965 se .0223; 2 seeds below 0; worst5 -0.552 (9991691), -0.387 (9991141), +0.345 (9991276), +0.405 (9990176), +0.509 (9991049). Peaks 222,652 to 225,355; 0 out-of-gas.\n- All LEAN pairings against qt1 (lb-4's 512, cf 1856, rp 768): n 3136, +3.170 se .017. All LEAN runs: 3,168 seeds, 34,419,397 callbacks, peak 225,355, 0 out-of-gas.\nThe replica (+3.16) and the release engine (+3.17) agree: the wheel's arithmetic is the port's.\n\nOTHER CONTRACTS, none better than lb-4 (engine peak; E against qt1). Episode 9's notes list la-1, la-2, lb-1, lb-2, sl-1, sl-3, sl-4. Read since: lb-3 240,384, n 448 +3.185 se .044; lb-5 240,264, n 352 +3.217 se .060, min -1.774; sl-2 232,387, n 256 +3.128 se .058. Not candidates: la-4 (249,025 and 1 out-of-gas on its E seeds); la-5 (G passed on 8 seeds, then an E window peaked at 249,087; n 512 +3.183).\n\nWHAT IS LEFT, MEASURED on the replica against LEAN:\n- The call is solved: the true flag adds +0.0066 se .0056 (go-1, 64000..64511) and +0.0058 se .0061 (go-2, 64512..65023).\n- True price in place of the belief (ORACLE): +1.183 se .030 and +1.193 se .030. On each item's first 128 seeds most of it is the arb's own trade (+0.85 of +1.11; +0.92 of +1.35): knowing a step's price before the arb shows it, which no policy has. Belief error: 0.04 bps at a pin, 10.5 bps six or more steps after; steps 3 or more after a pin hold +0.42 and +0.57.\n- True rival spot after each event (go-2): +0.213 se .018; on top of the true price +0.338 se .019. go-1's rival arm read the rival before its leg (-7.5): its timing, not a finding.\n- rc-joint: a 64-particle (price, rival) filter, only its rival estimate used: +0.145 se .015 over LEAN on 11024..11535 (+3.277 over qt1), gas ignored (192 state values); its price belief loses (-0.083 on choose). The rival gain is reachable, but not within 245,000 gas.\n- Closed: rc-band (rival band cuts the belief after retail calls) -177.5 se 2.2 on 10000..10511, and go-2's oracle band loses too (-0.63); rc-scale (per-run volatility and rate) nothing above 0 on choose (best -0.004 se .010).\n- Tables: Taylor's full 1e-5 tables in LEAN are +0.111 se .012 over LEAN's compressed ones (kt-high, 10512..11023); R takes +0.047 of that at no gas. Information weight 2e-5 is -0.219 se .024 and 4e-5 -1.454 se .045 against 1e-5 (choose 64000..64255). kt-low (0 and 5e-6) BLOCKED: dp.py's solve did not finish in 475 s; not measured.\n- Earlier: lattice shape +0.008 se .008; a residual head +0.08 to +0.15 on COMBO at 51.5k gas (R has 22k of room).\nCausal and measured beyond R: about +0.06 (table fidelity) and +0.15 to +0.21 (rival), against the +0.3 to +0.4 that #1 needs: no measured route reaches #1 inside the gas cap.\n\nFOR THE REQUESTER AND THE USER. Nothing was submitted; no submission is decided here. The tell reads the simulator's floating-point arithmetic (which code path made a trade's wads), not the market: whether the puzzle's rules allow that, and whether the board's server rounds as the release wheel does, are theirs to weigh first. Local pairings are not board scores. Single-seed edges of a tell policy move with a machine's libm; paired means do not.\n\nCREDIT in the write-up: Taylor (gtmcknight) first, then the seats in episode 9's notes (qt1, TC-A #770, o1-a #541, o1-b #1497, tca-path #1351, buy-grid #781, visit-refit #307, lb-4 #39 and the other builders) and the e09 items by name.\n\nSEEDS. Engine, consumed or reserved, never recycled: episode 9's ledger, with 9991344..9991535 reserved and not run. Next fresh 9996000.\n\nURLS (https://api.imdnotdead.fun/artifacts/ + sha256 of a result's bytes): rp-3 31c415ffbbcdc36d91a30d4f4a8817406d3ab96b34df29d08ac28ad3e41432ba; lb-4 93cc15561f172c49c8bce174143333ede904fdbfcf51276cbbeb514d4f5b614e; tca-path dc359635b5851de9f5b3ecf81dc2107d46acd5dbe67e0be234bcfbe0c8a488e7.",
