Beat this network's AMM entry qt1 on paradigm.xyz/puzzles/amm (board 524.9403, 8th; 7th is 525.377, +0.44; 6th 526.777). qt1 is Taylor (gtmcknight)'s solved policy (github.com/gtmcknight/amm-sim at 4812a6382311624e1506aca131ca35c378f930d9, research/solved) in Solidity: Gaussian filter plus the qm tables compressed by qm-spline. qt1 = the Solidity block of https://api.imdnotdead.fun/artifacts/8a6e303b662e1a5ea9bb47f31acedd3988ef65b3ddb66d074517aa59ad41ca40, sha256 c68887cff61180e12ba2b1ceb333edf76a830f91f63b5d775a8806fb9ec08aca; that result also holds its Python reference. Two leads, measured on Taylor's replica (links in note 1): quoting against the whole two-part posterior at a step's first trade (+0.49 over Gaussian + plain, 2 to 4 table lookups), and a cheaper lattice filter (lattice + qm is +0.49 over Gaussian + qm, but the exact lattice costs 453k gas a call).

LIMITS: deployed bytecode <= 24,576 bytes; engine afterSwap peak <= 245,000 gas and 0 OutOfGas (qt1 peaks at 208,775).

GATES: (P) Taylor's gates.py reproduces before any change; (Q) each new Python reference is scored paired against qt1's reference on Taylor's replica (choose on 60000..61023, report 10000..12047); (F) the contract's fees equal its Python reference within 0.01 bps on 50x2,000 callbacks from replica runs.

REPLICA work: plain python3 -I, any machine. ENGINE work: the Linux setup below; each strategy alone vs the 30 bps VanillaStrategy, amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8), configs per MatchRunner._build_configs; fresh seeds from 9800000 up, never reused; report paired{n,mean_diff,se,worst5} vs qt1 and amm_sim_rs.gas_stats(). No command over 8 minutes; state under scratch/. Credit Taylor in the header.

SETUP: clone github.com/benedictbrady/amm-challenge at 6b6921f8d463314aa7c96234e1be25a25245f704 in your workspace (never /tmp), save the script below as scratch/setup.sh, run sh scratch/setup.sh once from the checkout root, prefix later commands with . scratch/env.sh && ; on failure return blocked={step,error}.

The answer

AMM deliverable — credit Taylor (gtmcknight)

Taylor (gtmcknight) authored the solved policy, Gaussian/lattice filters, qm tables and replica used here, pinned at amm-sim 4812a6382311624e1506aca131ca35c378f930d9.

Recommended handoff: TC-A, TaylorTwoCompQmTrim2, saved as Strategy.sol from the complete block below. Its source SHA-256 is b87234c89e094f4955578417c1266129b0f96e6dfda68e3fb8866e00eeda71a2 (44,963 UTF-8 bytes, including the final LF). Reported deployed runtime: 21,102 bytes. Recomputed confirmation: paired n=2,288, mean_diff=+0.445695240, se=0.011808320 versus qt1, with 211,164 maximum engine afterSwap gas and 0 OOG on those completed runs. This exceeds the requester's +0.3/2,048-seed threshold; P, Q and effective-fee F are reported passing. The engine measurements and their failures are detailed below. port-a root-1-02 b23-f2 b23-f3

ComboG(1) is the stronger observed candidate, but its final confirmation remains incomplete: +0.655450899 ± 0.014232195 SE on 1,824 completed fresh pairs, 22,058 runtime bytes, peak 220,843 and zero recorded OOG on those completed calls. Missing 224 pairs, incomplete compiler records and a blocked independent F audit prevent promoting it over the confirmed handoff. Its exact source patch and Python reference are included at the end for the next run. root-1-03 b24-merge-01 recovered-a1s1 recovered-a1s2 b25-merge-01

These are local engine gains, not a leaderboard score or a demonstrated new rank. The brief's board figures (qt1 524.9403; seventh 525.377; sixth 526.777) are historical task context. No board submission was made.

// (qm_k1e-5.json, +3.77 vs HA on Taylor's replica). Filter, state and timing from trim-1 / port-3.

// per table one 3-D cubic B-spline (row, column, sd level), clamped knots, coefficients int16 in 1/8 bps.
// The contract evaluates the spline at the 8 surrounding grid nodes (2 rows x 2 columns x 2 sd levels) with
// Cox-de Boor bases computed at runtime, clamps each node fee at 0, then interpolates bilinearly and linearly in sd
// exactly as real.py reads the decoded JSON. Bid side = point mirror of the ask surface (row 320-i, column last-j).
// Coefficient words are PUSH32 immediates written to memory: 4 lanes x 64 bits per word, lane = 4 int16 sd coefficients.
// Gas trim: scalar node sums, shared mirrored knot geometry, and four packed state words.
// Mirrored bases rerun the original recurrence, preserving its fixed-point rounding order.
// Knot words: interior knots as uint16 in 1/64 grid units (W[0..1] rows, W[2] columns).

The block above is byte-for-byte contracts/Candidate.sol in the goal repository identity-md-launches/goal-3170-beat-network-s-amm-entry, repository URL https://github.com/identity-md-launches/goal-3170-beat-network-s-amm-entry.git, final trunk commit 3c26cafb604388da55c1ab71e1bcfd1798c9e4ea. Its two imports are the standard files in the pinned amm-challenge checkout 6b6921f8d463314aa7c96234e1be25a25245f704; all strategy table coefficients are included in the block. It is a complete challenge strategy source, with those existing framework imports.

The recorded code waves reached these commits: initial references 31ff8ed128b463cde10ea0a71d354f8c54d4464a; tools/qtr2/TwoComp c1c9a349f00bf18746f17c6a253469df6634860b; TC-A freeze 4eb3e985fd31e3cd17832501b95b6d2491aca73d; Combo freeze 3c26cafb604388da55c1ab71e1bcfd1798c9e4ea. The last wave retained TC-A unchanged. The final trunk's README was written before confirmation settled; the measurements here supersede its “pending” labels, subject to the explicit gaps below. root-1-01 root-1-02 root-1-03

TC-A carries the first-trade arb point mass and retail truncated Gaussian separately, preserving their weights, means and variances through the step. At the next active step it applies two separate silent-step cuts before collapsing the components for remaining cuts; the silent loop cap remains 12. Quotes use the mixture moments with qtr2's original compressed qm lookup. Four packed storage words retain the belief. The table bytes, spline arithmetic and fee conversion remain those of qtr2; the source is the port-a implementation, not the different port-b binary. port-a

Gates and exact references

The immutable comparator is qt1, SHA-256 c68887cff61180e12ba2b1ceb333edf76a830f91f63b5d775a8806fb9ec08aca, runtime 20,605 bytes. Its Python reference is reference/qt1/qmref.py, SHA-256 1dfc9b7a3c2237ff7a93dd9f0af54b9bdab16f2ce0a7eb00784cb4432598db92; its decoded QMS1 blob is 10,167 bytes, SHA-256 3ac7cb8811ecfb6a17f499aa4e9b70dd55f7fb6432b3aec3b904e11a3dece38e. Gaussian + full qm tables is a different comparator. root-1-01

P was reproduced before changes by the port and gas-diet workers, and repeatedly in the baseline work. Their unmodified python3 -I gates.py printed:

Seed	Perfect information	Gaussian + plain	Gaussian + qm	Lattice + qm
10000	448.261189	443.455598	443.522608	443.663520
10001	576.779199	571.463409	571.623551	571.977293
10002	531.886497	525.168028	525.865859	526.411631

The compressed qt1 reference instead gives 443.101741 / 571.454483 / 525.908441 on these three seeds. Matching the full-table P column alone does not establish a correct qt1 comparator. port-a diet-ab1

Q used the stipulated choose window 60000..61023 (n=1,024) and report window 10000..12047 (n=2,048), full 10,000-step replica runs, paired against qt1's own reference. Values below are worker measurements:

Reference	Choose gain ± SE	Report gain ± SE	Exact reference identity
TwoComp / TC-A	+0.4454237154410953 ± 0.017637356353635045	+0.42480288330208926 ± 0.012201543529995695	TwoComp, DUAL_CUTS=2

TwoComp is reference/twocomp/twocomp.py, SHA-256 9d3c1833321493fb51bbde4e1b4dabc2f8978bd6d774ee2af8dc8aed13f0f0af (11,202 bytes). ComboG is reference/combo/combog.py, SHA-256 321c61dff43c1677722d4b52e066ed5296f08ac7b72465245f04eb04e1c143cb (6,011 bytes), importing the unchanged TwoComp. ComboG(1)'s gate was fixed by the gas rule before its scores were examined. port-a diet-ab1

F compares both returned contract fees with the effective Python fees after replica2.clampf, tolerance 0.01 bps. Each reference drives 50 runs, seeds 70000..70049, recording the first 2,000 own-pool callbacks, with a fresh contract deployment per run and 245,000 gas per call.

Contract	Callbacks	Maximum fee error, bps	pyrevm peak	OOG	Evidence
TC-A	100,000	6.304438181356162e-06	178,312	0	port-a
ComboG(1)	100,000	3.0968576748141574e-06	203,056	0	diet-ab1

TC-A's maximum occurs at seed 70021, callback 1192; ComboG's at 70003, callback 655. TC-A's separate full-trace long-silence probe covered 107,708 callbacks and 13 qualifying dt≥13/two-component arrivals, peak 177,611. These pyrevm values are distinct from engine transaction gas. No universal gas bound follows from either sample. port-a diet-ab1

Clamping is material: pinned QMRef can return an uncapped local fee while storing a capped fee, and the replica caps it before execution. Literal raw-return comparison fails even for qt1 at seed 70026, callback 1702, by about 200.0793 bps. Thus the reported F passes mean equality of the fees actually applied by the replica; raw-return identity is not claimed. qtr2-loads' reported F failure used the raw interpretation. root-1-01

The independent final Combo audit reproduced P and only three reference spot checks; Linux wheel installation was unavailable on its platform, so it did not repeat full Q, F or the gas probe. The freeze wave checked packaging and reference spots, not those engine gates. Combo's F evidence therefore remains the original diet worker's measurement. root-1-03

Engine confirmation and coverage

Each arm ran separately against the fixed 30 bps VanillaStrategy using amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8). The configs follow MatchRunner._build_configs, including per-seed NumPy draws in size/rate/sigma order and 10,000 steps. The paired observation is candidate.edges["submission"] - qt1.edges["submission"], using the same config in the two separate runs. The raw gas role Baseline means Vanilla, even in the qt1 arm. Gas counters reset before each arm. root-1-02 recovered-a1s2

For n differences d, this report computes mean=sum(d)/n and SE=sqrt(sum((d−mean)^2)/(n−1)/n), and sorts worst5 by difference then seed. It does not average shard SEs or pool different source hashes. Completed rows are retained regardless of sign; missing or interrupted rows are never zeros. Original TC-A CSV rows have 12 decimals; f2/f3 preserve engine floats. Combo b1s3 has 128 rows rounded to six decimals, so its aggregate's extra displayed digits are arithmetic on rounded inputs.

TC-A block accounting:

Pool	Inclusive seed coverage	n	Mean difference	SE

The first A chunk 9801986..9802001 was lost to an import error before simulation. f1 (9803188..9803315) returned no paired/gas data: all eight chunks timed out at 470 seconds. These ranges remain retired. The successful 2,288 pairs alone satisfy the requested count and mean threshold; 1,830 were positive and 458 negative. They exclude the original 128-seed port screen and two-seed smoke test. b15-a2s4 b23-f1 b23-f2 b23-f3

Root merge 3 separately reports the predeclared gap replacement on 9805620..9805635: n=16, mean=0.4301337736878672, SE=0.1769866300149901, runtime 21,102 and a candidate gas-limit pass. Its original per-seed table/raw gas was not handed to this write-up. Combining that reported sufficient-statistic tuple with the available rows gives repaired A n=1,024, +0.447612321, SE 0.017177498; repaired A+B n=2,048, +0.440854464, SE 0.012530314; and all confirmations n=2,304, +0.445587175, SE 0.011786588. These three pools include secondary-summary evidence. They are not 2,304 independently rechecked rows, and the 211,164 headline peak is explicitly the 2,288-row pool's peak. The gap's raw counters are missing here, so no exact 2,304-run gas sum or peak is invented. root-1-03

The supplementary mean/SE is combined using M2=sum((n_i−1)n_i SE_i² + n_i(mean_i−pooled_mean)²), then SE=sqrt(M2/(N−1)/N). The gap's worst five are −0.865643364170, −0.426550783233, −0.350974846867, −0.308009921003, +0.002209517873, all above the global worst five below. The repaired 2×1,024 interpretation therefore depends on that root summary, while the 2,288-row threshold result does not.

Every completed TC-A row in that table has zero recorded OOG, revert, other_halt, tx_error and bad_return counters. This excludes f1's unknown execution counters; a timeout is not proof of either OOG or no OOG.

Worst five paired differences in the row-backed TC-A and ComboG pools:

Rank	TC-A seed	TC-A difference	ComboG seed	ComboG difference

5	9802327	-1.537003428135	9804027	-1.193633371605

These negative tails coexist with the positive means. A mean improvement does not imply improvement on every seed.

ComboG(1): larger observed gain, incomplete confirmation

Frozen source SHA-256 f904a486b1dcfbd6fcf40aa48920d1bb6b79ad2ac1c99a2cbbb16d4272c2c616; runtime 22,058. At ambiguous first trades with dt=1, ComboG averages the two posterior branches' qm offsets, then converts once to fees. Other callbacks use TwoComp's single lookup. The sd=0 arb branch specialization, upper-bound knot searches and zero-sd coefficient shortcut make the extra lookup affordable. DUAL_CUTS=2 and silent cap=12 remain unchanged. diet-ab1

Recovered a1s2 is new evidence recovered during this write-up from the content-addressed original linked by the blocked merge; its 128 pairs were not present in root merge 3's arithmetic. Its content hash matches the supplied expected hash. Recovered a1s1 confirms patch: command not found (exit 127), before any simulation. Its accidental validation of unpatched TC-A is not Combo validation. b24-merge-01 recovered-a1s1 recovered-a1s2

Block A (assigned 9803572..9804595) has n=800, mean=+0.702131781, SE=0.021673628. Block B (9804596..9805619) has n=1,024, mean=+0.618981459, SE=0.018797808. Combined: n=1,824, mean=+0.655450899, SE=0.014232195, with 1,593 positive and 231 negative differences. No TC-A, port-b or GATE 4 observations enter this pool.

Missing A ranges are 9803572..9803699 (128) and 9804244..9804339 (96). For the latter, 9804244..9804259 was interrupted by SIGTERM from an enclosing 120-second shell limit; the output had empty arms, so its edges and gas are unknown. The remaining 80 seeds were unattempted. Every range remains retired; the missing 224 cannot be filled by reusing it. b25-merge-01

Compiler metadata is incomplete in several shards. Source/helper hashes, pinned checkout, runtime lengths and some bytecode hashes support compatibility; they do not directly establish every worker's full compiler input. Even b27-merge-02's “complete” label infers b2s3 settings from the pinned compiler rather than recording them. b1s2 and b1s3 omit Vanilla-role raw gas; their Submission counters are available. These are retained evidence gaps, not invented compiler mismatches or measured gas failures. Together with the absent 224 pairs and independent F replay, they leave Combo preliminary. b24-merge-02 b25-merge-02 b26-merge-01 b26-merge-02 b27-merge-01 b27-merge-02

The gd-ab-1 engine diagnostic on 9800000..9800007 and gd-abc's 9800000..9800031 diagnostic are excluded: the ranges had already been reserved by episode 1, regardless of a worker's “fresh” label. This report consumes no new engine seed. All allocations through 9805635 remain unavailable; the recorded next free seed is 9805636. diet-ab1 root-1-03

Engine gas accounting

These are sums/maxima of the supplied amm_sim_rs.gas_stats() records for the completed row-backed pools. Calls equal successful calls; each displayed error value is the sum of OOG, revert, other_halt, tx_error and bad_return, all individually zero. Mean gas is sum_ok_gas / ok, not an average of chunk means.

Pool	Submission arm	Calls = ok	sum_ok_gas	max_ok_gas	Mean gas
TC-A	candidate	24966949	3270871667956	211164	131008.064620

TC-A confirmation includes 143 completed 16-seed chunks per arm; Combo includes 114. Initialization peaks are TC-A 92,165, Combo 92,178, qt1 90,858. TC-A leaves 33,836 observed gas headroom and 3,474 runtime bytes; Combo leaves 24,157 gas and 2,518 runtime bytes. The brief's qt1 peak 208,775 was from an earlier sample; qt1 reached 209,462 here without violating the cap.

TC-A's full role/callback records cover all 2,288 completed seeds. Combo's available Vanilla-role totals cover only 1,568 seeds because b1s2/b1s3 omit that role; no full 1,824-seed Vanilla total is asserted. No “zero errors” claim covers f1's timed-out runs or Combo's interrupted chunk. The underlying raw per-chunk gas records remain in the linked result artifacts.

Research lines and what they established

Replica gains below are against compressed qt1 unless explicitly marked otherwise. “Choose half” means only 60000..60511, n=512; it is not full Q. A missing engine result means not measured, not zero gain. Early screens and differing contracts are not pooled into final confirmation. root-1-01 root-1-02

Cuts-8's prose had a sign error: its choose change versus cuts 2 is −0.002385901, not positive. Roots disagree on modeled truncation counts; neither count is an engine measurement. The full-table lattice's quoted 453k gas and the coarse lattice's operation-cost estimates use different evidence and are not interchangeable.

Gas-only work:

Line	Measured outcome	Engine score / status
qt1 basis optimization	21,653 bytes; peak 196,323 vs 206,830 (−10,507)	32 seeds 9800256..9800287: every edge identical; F identical

qtr2's approximately 17–18k peak saving created the port's gas headroom; its floating-point/fixed-point trajectory comparison to qt1 is nearly, but not exactly, edge-identical. The span patch's output equality is against qtr2. root-1-01

The primary gd-ab-1 seed-70000 trace reports dt 1 peaks 215,761 (port), 216,724 (support refactor), 215,710 (sd-axis shortcut), 210,087 (span searches), 201,077 (zero-sd coefficient shortcut), then 201,294 (rejected buffer reuse). Retained reduction is 14,684 gas. Root merge 3 gives a different intermediate progression; this report uses the directly re-read, hash-verified primary artifact. The five-seed maximum 203,136 is a different aggregate. All retained stages returned the same 8,987-callback fee-output digest on seed 70000. diet-ab1 root-1-03

Gas-selected GATE 1 is not choose-score-best GATE 2. The frozen diet's ungated bucket peaks are dt 1=203,136; dt 2=208,069; dt 3=207,200; dt 4=206,025; dt 5–6=218,148; dt 7–9=225,296; dt 10–12=237,385; dt≥13=235,607. Every larger allowed gate includes dt 2, which exceeds 205,000. The shipped path uses mixed quoting only at dt 1. diet-ab1

The gate study's paired gains (choose/report) were: GATE 1 0.637084401/0.602894269; 2 0.645661931/0.606664298; 3 0.640709798/0.613015584; 4 0.637421242/0.601755886; 6 0.636230026/0.598820846; 9 0.637092833/0.597451741; ungated 0.637902004/0.597390963. Choose SEs are approximately 0.0192–0.0198, report SEs 0.0130–0.0136. GATE 3's larger report score is not a basis to retune on the holdout. root-1-02

Cross-platform choose baselines differed on 17–19 seeds, shifting means by about 4e−6; the report baseline reproduced. Pair new references against a local qt1 recomputation. Some original reports had failed external-source rechecks, recorded in the roots and goal snapshot; matching content hashes and internally consistent arithmetic do not turn those reports into independent certification. No cancelled or unfinished cuts/lattice work is counted as a successful gate. root-1-01 root-1-02 root-1-03

Next run and reproduction

The next useful experiment is completion of the frozen ComboG(1) confirmation, without changing source, gate or filter. The recorded next-free range would allow 224 replacement seeds 9805636..9805859, bringing observed A to 1,024 and A+B to 2,048. This is a proposed future allocation, not a run or reservation made by this report. Preserve B and every successful A row, append all replacement rows, and recompute the paired result. Do not rerun any range through 9805635.

A bounded batch brief for that work is: “One item confirms one assigned, disjoint 16-seed range of frozen ComboG(1) versus pinned qt1, each alone against 30 bps Vanilla with the stipulated config builder and eight threads. No tuning or other engine seeds. Return source and creation/runtime bytecode hashes, explicit compiler input/settings, validation/runtime size, every paired seed row, paired{n,mean_diff,se,worst5}, complete unfiltered gas_stats for both arms after each invocation, and attempted/completed/missing ranges with command exits/errors. Persist each arm immediately, stop on an error, and never retry a spent seed.” Fourteen items would cover the 224 replacements. This asks each item for one confirmation shard and specifies its evidence.

A separate single-item audit brief is: “Replay the unchanged frozen ComboG(1) contract against its exact Python reference on 50×2,000 callbacks, seeds 70000..70049, and run the full dt-bucket probe on 70000..70004 on the supported Linux setup. Return P output, exact source/reference/compiler hashes, all F row counts/errors, every observed bucket's call count/peak/OOG, runtime/validator output, and any failure. Do not run engine seeds or tune.” Replica seeds may repeat. This closes the audit left incomplete in the last wave. Archive missing compiler/bytecode provenance and full-role gas logs where recoverable; infer neither from an accepted-item label.

Only promote Combo after the frozen file satisfies P/Q/F, runtime≤24,576, measured engine peak≤245,000, zero OOG, and ≥+0.3 on 2,048 completed fresh pairs. Its present mean does not waive the sample requirement. A later gas-only attempt at GATE 2 would be a new frozen reference/contract requiring its own Q/F and fresh engine confirmation; do not select GATE 3 using its report-window score.

For reproduction, use the goal trunk and challenge commits given above. Preserve final LF in every extracted block. The challenge compiler settings reported for these builds are solc 0.8.24, optimizer enabled/runs 200, viaIR=true, evmVersion=paris. The pinned compiler supplies the two standard Solidity imports. Engine setup is the objective's script saved to scratch/setup.sh and executed once from the challenge root, then commands start with . scratch/env.sh && . The wheel digest is aedb68280aca34c110968f00148387c95885207913fb2cf19a1ab4c5cfd6887a; do not substitute another engine.

The trunk supplies tools/check.py (SHA-256 cbcfea4c793ac7b78e0ee27dd723c9e6af4d9d704a70a8038c985acffffcfed1) and tools/engine.py (306c529d0c84c88610c1e8a9a6aa34634534b73ab83312e9155ef14476e46300). Keep the tools together: engine.py imports check.py. With TASK_ROOT set to the goal checkout, from the prepared challenge checkout:

. scratch/env.sh && timeout 470 amm-match validate "$TASK_ROOT/contracts/Candidate.sol"
. scratch/env.sh && timeout 470 python "$TASK_ROOT/tools/check.py" "$TASK_ROOT/contracts/Candidate.sol" twocomp.TwoComp 70000 70010 scratch/F_tca_70000_70010.json
. scratch/env.sh && PYTHONPATH="$TASK_ROOT/reference/combo" timeout 470 python "$TASK_ROOT/tools/check.py" "$TASK_ROOT/contracts/Combo.sol" combog.ComboG 70000 70010 scratch/F_combo_70000_70010.json

Repeat F in disjoint ten-seed chunks through 70050 (exclusive) to obtain all 50 runs. These example ten-seed commands alone are not full F. For a newly allocated engine chunk, call the engine tool with arguments CANDIDATE_SOL QT1_SOL START END scratch/unique-output.json, END exclusive; never use a historical seed just to reproduce a score. Keep each command≤470 seconds, run chunks sequentially per item, and ensure enclosing execution limits exceed the child limit.

Replica work uses plain python3 -I; explicitly add the pinned reference/taylor, reference/qt1, and desired policy directory to sys.path. Run unmodified Taylor gates before policy changes, then score both policies per seed on choose/report windows. Diagnostic edges for TC-A are 443.690614/571.968071/526.124475 and ComboG(1) 444.306611/571.876123/526.150746 on 10000..10002. These spots do not replace full Q. port-a diet-ab1

The trunk is not a bundled offline simulator: its README explicitly omits Taylor's 7,892,018-byte qm_k1e-5.json (SHA-256 5ff53e42ca87390e5f65d1caa3f7a480e67a8212fb0670274dfd562b05ba1afd), required for P, and setup fetches the engine/compiler. No dependencies were installed or added during this report-only task. A future offline replay package must include those ordinary files; the embedded Strategy itself introduces no dependency beyond the pinned challenge framework.

Write-up checks and close-out record

This write-up read all 30 supplied artifacts and the goal/skill-reference records as data. Local checks recomputed TC-A statistics from 2,288 rows and raw gas records, and Combo statistics from 1,824 rows including the recovered 128-row artifact. They checked unique/disjoint seeds and range gaps, per-row subtraction at the source's precision, pooled SEs/worst5, gas sums/maxima/error counters, and artifact/source SHA-256. The Combo diff below reconstructs the pinned 47,171-byte source exactly; its Python block equals the pinned reference. Markdown fence/reference integrity, source hashes, JSON shape, byte limit and final file scope were checked. No new simulation, Solidity compilation, P/Q/F replay or board submission was performed during this write-up. These consistency checks have no independent authority to certify worker behavior.

The assignment names only report.md and forbids other outputs. The archival decisions object is therefore embedded here, as one JSON object in the supplied reference's shape; it dispatches no work. “finish” closes this write-up, not Combo's missing confirmation or a leaderboard claim. Historical batch briefs in the snapshot are abbreviated, so their full text cannot be re-certified here; the two proposed future briefs above each define one item's work and its result.

{
  "notes": "Deliver TC-A with complete source and row-backed 2288-seed confirmation. Preserve the separate 16-seed gap summary and incomplete ComboG(1) evidence, including 224 missing pairs and audit/provenance gaps. Recommend future completion without tuning or reusing engine seeds. No board submission or new batch is made by this write-up.",

Exact frozen ComboG(1) reconstruction

The complete lead Strategy.sol is above. To recover the stronger preliminary alternative, apply the following exact unified diff to an unchanged copy of TC-A named Candidate.sol (patch -p1 or git apply -p1 from the intended scratch directory), then save the result as Strategy.sol. The output must be 47,171 bytes, SHA-256 f904a486b1dcfbd6fcf40aa48920d1bb6b79ad2ac1c99a2cbbb16d4272c2c616. Direct complete source: contracts/Combo.sol. The diff's SHA-256 is ee1e263770b2beecda27dbf2b85365c6536dd1e6f4c69f3ed5ad6451d39290b2 (10,251 bytes). This appendix contains every change, including all lookup trims; it is not an illustrative excerpt. diet-ab1

"""COMBO = two-component filter + weighted-average offset quoting.
Credit: Taylor (gtmcknight) -- replica, Gaussian filter, fee rule and qm tables
(github.com/gtmcknight/amm-sim @4812a638, research/solved); qt1 reference (QMRef),
TwoComp (two-comp item) and the wavg-offsets quoting (MIX item) are IdentityMD items built on them.
Standard library only. Needs twocomp.py (the TC artifact's Code block, unmodified) beside it.
usage: from combo import Combo; Combo('blob.bin') is a replica2 policy (wants_j).

Filter and carried state are TwoComp's, statement for statement (DUAL_CUTS=2).
Only the returned/stored fees differ, and only on a step's first own trade with .005 < pi < .995:
  arb branch    (pi,   lp, 0 ): offsets at phase 0, sd 0, rival clipped to lp's band
  retail branch (1-pi, mt, vt): offsets at phase 1, sd sqrt(vt), rival clipped to mt's band then
                                moved by this trade as a retail fill (its own synced flag)
  a = pi*a_arb + (1-pi)*a_ret, b likewise; fees converted once against the carried mixture mean.
Both branches start from the pre-step rival estimate. Nothing is tuned.

It must print, to every digit: 10000 448.261189 443.455598 443.522608 443.663520; 10001 576.779199 571.463409 571.623551 571.977293; 10002 531.886497 525.168028 525.865859 526.411631. Report the printed table and the Python version. A mismatch is the finding: report it and stop. 2. Put qmref.py and blob.bin in research/solved. `replica2.run(seed, QMRef('blob.bin'))['edge']` for seeds 10000..10002 must give 443.101741 / 571.454483 / 525.908441. 3. Only then: run qmref on replica seeds {{s0}}..{{s1}} ({{n}} seeds) with multiprocessing.Pool, each seed once, recording every seed's edge to 6 decimals. Time 16 seeds first; if the window will not finish within 40 minutes, stop at a contiguous prefix and say which seeds you covered.

Check the sha256s Q states. Background (T research/solved/README.md): at a step's first own trade the filter forms a two-point mixture: weight pi on the arb reading (price exp(lp), sd 0, phase 0, rival clipped into the band), 1-pi on the cut prior N(mt, vt) (retail: phase 1, cnt 1, rival updated by the trade). qt1 collapses it to one Gaussian and does one lookup per side. Quoting against both parts measured about +0.49 at 2 to 4 lookups. Build: copy qmref.py (with blob.bin; qmref on replica seeds 10000..10002 gives 443.101741 / 571.454483 / 525.908441) to scratch/mix.py. Change only the quoting at a step's first trade when 0.005 < pi < 0.995: look up offsets (a, b) for the arb part at (w from lp, R from the clipped rival, sd 0, phase 0 table) and for the retail part at (w from mt, R from the trade-updated rival, sd sqrt(vt), phase 1 table, synced as the update says), then combine them as {{rule}}. Carried state (m', v', s2, synced, cnt, phase, fees) stays as in qmref; every other callback is unchanged. Screen: run qmref and mix.py on replica seeds 60000..60511, each seed once, multiprocessing.Pool; pair per seed (mix minus qmref). Time 16 seeds first; if the window will not finish in 40 minutes, stop both at the same contiguous prefix and say so; never pass off a partial figure as a result.

Approach: {{design}} Method: each strategy alone vs the 30 bps VanillaStrategy via amm_sim_rs.run_batch(X, VanillaStrategy, configs, 8), configs per MatchRunner._build_configs per seed, gas_stats_reset()/gas_stats() around each chunk; T's harness.py does this: `python ../amm-sim/harness.py CAND.sol S0 S1 out.json [--other OTHER.sol]`. Chunks of <= 32 seeds (~50 s each for qt1), no command over 8 minutes, each seed once, nothing re-run. Run Qt1Fast and Qt1 on engine seeds {{s0}}..{{s1}} (32 seeds, each once per strategy). Per-seed edges must be identical (list any differing by over 1e-9). Result (markdown, under 64 KB), sections: Changes (each edit, why, gas saved); one fenced JSON block with keys approach, seeds, n, runtime_bytes {qt1, fast}, gas {qt1, fast} each {afterSwap {calls, oog, peak, mean}, afterInitialize {peak}}, edges_identical, mean_diff, differing_seeds; Code: the complete Qt1Fast.sol in a fenced block, or a unified diff against Qt1.sol; Commands (every command run); Problems.

EPISODE 1 (2026-11-10). Nothing had run. Decided: 7 small batches, 16 items (of 120), gates and screens before any wide spend. FACTS CHECKED THIS EPISODE (from the sources, not from results yet): - Artifact Q (qt1, https://api.imdnotdead.fun/artifacts/8a6e303b...) is a markdown report: sections Setup and Gate P, Reference (qmref.py), Contract design, Size (runtime 20,605 B), Gate F (replica seeds 70000..70049, 50x2,000 callbacks, max 5.83e-6 bps, pyrevm peak 194,051 at seed 70032, mean 124,777), Engine (seeds 9535000..9535127: qt1 mean 533.05, +0.819 se 0.055 over trim-2, +2.16 over t03; afterSwap peak 208,775, mean 137,940, 0 OOG in 1,402,238 calls; ~51 s per 32-seed chunk), Notes and limits (headroom: binary search for knot spans ~2.3k per basis eval, 4 per surface; coefficient dispatch ~360 gas per word; each surface 35-43k), '## Strategy.sol' fenced block (sha256 c68887cf..., 42,990 B; contract Strategy is AMMStrategyBase; no assembly), '## Python reference' fenced block qmref.py (stdlib; QMRef('blob.bin') is a replica2 policy; checks 443.101741 / 571.454483 / 525.908441 on seeds 10000..10002). qmref needs the QMS1 blob: base64 under '## Data' of artifact 17d249ab... (qm-spline), decoded 10,167 B sha256 3ac7cb88.... - Taylor's repo at 4812a638: research/solved has replica2.py, real.py (Gaussian), latt.py (121 cells x 2.5 bps, class LatticePolicy over RealPolicy), evalpol.py (stats, CALIB), gates.py, track.py, dp.py/qmdp.py (solver, numpy+numba), pol_mid.json, qm_k1e-5.json (7.9 MB), calib_out_2048.json. Root has harness.py (paired engine runner: python scratch/harness.py CAND.sol S0 S1 out.json --other V2.sol, with gas_stats) and setup-fast.sh (= the objective's setup script without numba and cma; same instrumented wheel, same env.sh). Engine briefs name setup-fast.sh (its raw URL) to fit the 3,000-char brief limit; it also goes into the trunk as tools/setup.sh. Add `numba cma` to the uv pip install line only for solver items. Gates table: 10000 448.261189 443.455598 443.522608 443.663520; 10001 576.779199 571.463409 571.623551 571.977293; 10002 531.886497 525.168028 525.865859 526.411631. README numbers on 10000..12047 vs HA: lattice+qm +4.26, gaussian+qm +3.77, gaussian+plain +2.83, real inputs + true arb flag +6.98 (the first-trade arb/retail call is wrong 16% of the time; worth 2.7). Not tried by Taylor: quoting against the whole lattice posterior instead of mean/sd. - Gas budget problem for lead 1: qt1 spends 70-85k on its two surfaces; two more lookups at a step's first trade (which is also the callback with the silent-step loop) would push the peak near 290k. So gas reduction of the spline lookup is on the critical path: e1-gas-spline runs in parallel. - The replica is deterministic pure Python, so per-seed edges from different machines pair exactly: baselines can be published once and windows sharded across items. BATCHES SPAWNED (keys): - e1-gate-p (replica): p-choose (qt1-ref per-seed edges 60000..61023), p-report (10000..12047). Both re-run gates.py first. - e1-engine-base (engine): eb-a seeds 9800000..9800127, eb-b 9800128..9800255. Validate, size, per-seed edges, gas_stats. - e1-gate-f (engine+replica): gf-a replica seeds 70000..70049 (expect qt1's numbers), gf-b 70050..70099. Each returns the full check.py. - e1-lead-mix (replica, lead 1): mix-wavg-offsets, mix-wavg-fees, mix-max-fee; screen window 60000..60511 paired vs qmref. - e1-lead-latt (replica, lead 2): latt-c5, latt-c10, latt-k24, latt-two-comp; same screen; plus op counts and gas estimate. - e1-gas-spline (engine): gas-basis seeds 9800256..9800287, gas-dispatch 9800288..9800319; fees must stay identical. - e1-trunk (code, 1 item, scope README.md .gitignore reference/** tools/**): seeds the repo with qt1's files, Taylor's research/solved (without the 7.9 MB qm json), tools/setup.sh (= setup-fast.sh; the objective's script adds numba and cma for the solver). SEED LEDGER (engine seeds are never reused): used 9800000..9800319; NEXT FREE ENGINE SEED 9800320. Replica: 60000..60511 screens; 60000..61023 choose; 10000..12047 report; 70000..70099 Gate F. PLAN FOR EPISODE 2: 1. Read all 16 results. If gates.py or the qmref check failed anywhere, settle Gate P first: rerun on 2 other machines before trusting anything. 2. From e1-gate-p keep the per-seed qt1-ref edge tables (ask in read if not handed). From eb-a/eb-b note wall time per chunk and the peak; from gf-a the check.py text (put it in the trunk under tools/ in the next code wave). 3. Lead 1: pick the rule with the best mean_diff/se on the screen (+0.3 or better with mean_diff > 2 se is a go). Lead 2: rank by mean_diff and est_gas; drop anything whose est_gas plus two lookups puts the peak over ~230k. Then run the full Gate Q windows on at most 2-3 finalists, sharded: 60000..61023 in 4 items of 256 and 10000..12047 in 8 items of 256 per finalist (per-seed edges are deterministic; shards sum), each item reporting the variant's per-seed edges only (baselines come from e1-gate-p). Use seconds_per_seed from p-choose to size shards. 4. Contract: a code wave on the trunk: contracts/Candidate.sol from Qt1Fast (the better gas item) plus the chosen lead; tools/check.py (Gate F) and tools/engine.py; then engine items: candidate vs qt1 paired on fresh engine seeds from 9800320, 128 seeds per item in 4 chunks, gas_stats per chunk; Gate F on 70000..70049. 5. Budget guide: ep2 ~30 items, ep3 ~30, ep4 ~20, ep5 ~15, ep6 write-up. The final deliverable must carry paired{n, mean_diff, se, worst5} vs qt1 on the engine, gas_stats, the Gate F figure, the runtime size, and Taylor credited in the header. 6. If both leads screen flat or negative: fall back to gas headroom + finer tables (Taylor's open item 4: a 2.5 bps solve, or a kappa retune) and to the arb/retail classifier features (worth 2.7 per Taylor); any table change needs the numpy+numba solver (dp.py ~80 s on 14 cores; qmdp.py) and should be one research item first.

First reproduce unmodified gates.py/README (Gate P). Also check qmref scores 443.101741/571.454483/525.908441 on 10000..10002. No policy edits before P passes. Use only features obtainable from callback inputs and stored observable history; hidden price/arb labels may train or diagnose offline, NEVER enter the deployed policy. Explain feature availability and avoid lookahead. Preserve qm tables, fee lookup/conversion, and other filter behavior; alter only first-trade posterior odds using the extra features. Keep correction tiny enough to port onto qtr2 (requester's base); no Solidity or engine work here. Choose parameters ONLY on 60000..61023 (fit 60000..60511, select 60512..61023; at most three parameter sets). Freeze selected module, parameters and SHA256 before opening report seeds.

Reference checks on 10000..10002 are baseline-only; never use those checks to tune. Return full candidate module and runner, exact commands/hashes/dependencies and chosen parameters, observed-feature rationale, P reproduction, separate choose/report paired{n,mean_diff,se,worst5} (sample SD(diff)/sqrt(n)), baseline/candidate means, cost per seed, classifier diagnostics and Solidity operation/storage cost estimate (not measured gas). Return all 3072 paired differences losslessly as zlib+base64 packed little-endian float64: choose ascending, then report ascending; give SHA256 of decoded bytes and decoding command. This fits 64000 bytes with code; do not paste huge trace logs. A partial window is NOT Gate Q: if time prevents completion, label incomplete, give completed/missing intervals and scripts for deterministic sharding; never fabricate missing scores.

EPISODE 2, 2026-11-10. Decision retry after invalid_output: wake.batches previously exceeded ten. This file names only EIGHT wake batches. No result was handed over. All 16 episode-1 items show waiting=total, running=accepted=failed=0; e1-trunk wave state is running but trunk is still null. There is no measured new winner, Gate P pass, or completed implementation from this goal yet. Do not promote a lead based on earlier notes' estimates. NEW REQUESTER DIRECTION: note 2 says use qtr2 as the contract base, while retaining qt1 as comparator. qtr2 artifact https://api.imdnotdead.fun/artifacts/18ca35cb47390b8e8c289b240d7836804692998ad64f84ef248c43d61e199f0b; Solidity SHA256 7b99afae570ef1627b0163fb21411f14c496b005a07c3966cc7323906dee664f. I fetched the public artifact and confirmed its fenced Solidity bytes/hash (43,073 bytes). Its reported runtime 19,945, engine peak 191,661 and 0 OOG remain prior-run claims, not our measurements. Crucially its 100,000-callback raw identity check was against qm-2, NOT qt1. It uses a four-word packed state and shared spline geometry; qt1 uses a different implementation. Therefore explicitly verify qtr2 against qt1's actual qmref, not just full-table RealPolicy. Also verified qt1's fenced block is 42,990 bytes with the objective's c68887cff61180e12ba2b1ceb333edf76a830f91f63b5d775a8806fb9ec08aca hash. No engine or replica computations were run in this planning episode. DECISIONS: - Keep e1-gate-p, e1-engine-base, e1-gate-f, e1-lead-mix, e1-lead-latt and e1-trunk. Their baseline, harness and Python screens remain useful regardless of contract base. - Cancel e1-gas-spline (two still-waiting qt1-only optimizations), replacing it with e2-qtr2-gas, three independent pieces: control audits unchanged qtr2; spans optimizes knot-span search; loads reduces table/patch overhead. Each redoes P and F against actual qt1 reference, proves any patch raw-identical to qtr2, then freezes before its fresh engine block. A failure returns diagnostics, never a purported pass. Each result must carry reproducible patch/scripts, not merely an idea. All use the EXACT objective setup script, including numba/cma. This replaces rather than silently modifies the old briefs. - Add e2-classifier, two independent Python hypotheses requested in note 1 and absent from episode 1: normalized trade size/direction and pin age/observable fill history. Each selects solely on 60000..61023 and freezes before 10000..12047; all scores paired against qmref. Full Gate Q is requested, in short checkpointed commands. If an hour is insufficient, the item must name missing intervals and return reusable code; partial scores are not Gate Q. No Solidity port or engine spend on classifier until selection/gates warrant it. - Five new items, conservative gross used=21/120, leaving at least 99 if accepted. Cancellation may release two seats; do not depend on that credit. No new code wave is queued while e1-trunk is unsettled; stage qtr2 and selected patches with the next integration wave. - Request 18 named research results (13 retained old + 5 new). The e1-trunk singleton should be handed automatically after merge; its item key is not exposed in the snapshot, so none is invented. Wake on all six retained batches plus the two new batches, or after 120 minutes. This is a future scheduler trigger, not a wait in this task. finish=false. SEED LEDGER: episode 1 reserved 9800000..9800319; no consumption is confirmed in this snapshot. Never recycle these ranges, including cancelled e1-gas-spline's 9800256..9800319, because cancellation may race dispatch. New reservations: qtr2-control=9800320..9800447; qtr2-spans=9800448..9800575; qtr2-loads=9800576..9800703. NEXT FREE ENGINE SEED=9800704. Each distinct arm runs once per assigned seed, alone vs Vanilla; pairing shares a seed across arms only. Never reuse a seed across items or for a tuned rerun. Record partial/failed attempted blocks as spent. Replica seeds may repeat: choose 60000..61023, report 10000..12047, Gate F 70000..70049 (existing gf-b uses 70050..70099). NEXT EPISODES: 1. First inspect failures/refusals and P/qmref baseline checks, then read all results and trunk status. gates.py's full-table Gaussian+qm check is 443.522608/571.623551/525.865859; qmref's compressed qt1 check is 443.101741/571.454483/525.908441 on 10000..10002. They are intentionally DIFFERENT references. Reject comparisons against the wrong one. P mismatch takes priority; investigate/reproduce on independent replica seats before trusting new policy scores. A missing result is unknown, not failure evidence. 2. Validate qtr2 equivalence, bytecode and engine gas before adopting patches. qtr2's claimed ~53k headroom may still not accommodate two extra spline lookups (qt1 report put two at ~70-86k); require measured engine peaks, not a projected saving. Keep independent gas patches separate until a combined patch is retested. If qtr2 fails against qmref, preserve the counterexample and repair the representation or introduce its exact reference and Gate Q explicitly; do not silently redefine qt1 or assume qm-2 identity suffices. 3. Select at most two posterior/lattice/classifier candidates using choose scores and feasibility only. e1 mix/lattice screens cover 60000..60511 and are NOT full Q. Run missing choose/report windows for fixed candidates, typically 256-seed shards once seconds/seed is known. Reuse verified deterministic qt1 per-seed baselines from e1-gate-p; pair by exact seed, combine raw differences (not shard SEs), compute sample SD/sqrt(n), and retain worst five. Do not retune using report scores. Classifier variants also require a new Q if combined with a different filter/quote rule. 4. Next code wave imports pinned qtr2, verified gas patch and selected policy, plus complete replay and engine harnesses into scoped paths. Leave qt1 baseline immutable. Credit Taylor in headers. Before engine promotion: P, full Q and F <=0.01bps on 50x2000 candidate-reference-driven callbacks, runtime<=24,576, measured engine afterSwap<=245,000 and no OOG. Use qtr2 for both posterior and lattice ports per requester note 2; ar3's two-lookup qs=0 fallback is a separate reference requiring Q/F if four lookups do not fit. Exact 453k lattice is infeasible; only a cheaper measured implementation can proceed. 5. Episode 4 can compare gated finalists on two fresh 512-seed engine blocks; freeze one for independent confirmation. As soon as a contract passes F/gas and merits confirmation, reserve TWO fresh disjoint 1,024-seed blocks, split among workers into bounded chunks, with no further tuning or reuse. Each strategy alone vs 30bps Vanilla via run_batch(...,8), configs per MatchRunner._build_configs. Report both blocks and combined paired{n,mean_diff,se,worst5}, every seed, and gas_stats (sum counts/gas totals, max peaks); sample SE, not unpaired comparison. At least +0.3 vs qt1 on 2,048 fresh seeds is requester's submission threshold. Two 512 screens do not satisfy it. 6. Preserve episodes 5/6 and remaining seats for confirmation, independent checks and a complete code+SHA256 handoff, not speculative widening. Budget roughly <=30 additional items for next Q/integration wave, <=20 for screens and <=20 for confirmation/repairs; adjust to measured timings. Finish only with documented actual results; never infer a new leaderboard score/rank from replica or local engine differences. Requester submits; do not submit externally.

the whole memo
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.imdnotdead.fun/artifacts/<sha256 of result.md> (checked: all eight below return 200 with matching hash). FACTS FROM RESULTS (all local measurements, none are board scores): - 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. - 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. - 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. - 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). - 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}. - 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. - 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). DECISIONS (10 items): - 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. - 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). - 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. - 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. - 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. SEED 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). PLAN FOR EPISODE 4: 1. 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. 2. 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. 3. 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. 4. 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. 5. 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.

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.imdnotdead.fun/artifacts/<sha256 of result.md>. FACTS FROM EPISODE-3 RESULTS (local measurements, not board scores): - 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. - 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. - 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. - 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. DECISIONS (22 items): - 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. - 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. - 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. - 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. - 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. SEED 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). PLAN FOR EPISODE 5: 1. 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. 2. 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. 3. 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. 4. 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. 5. 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).

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.

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). FACTS FROM EPISODE-4 RESULTS (local measurements, not board scores): - 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. - 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. - 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. - 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. DECISIONS (9 items): - 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). - 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. - 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). - Cancelled: e1-lead-latt, e2-classifier (dead leads running since episode 1-2), e4-combo-port (cp-c cannot change the gas verdict). - Wake when the three new batches settle or after 150 minutes. SEED 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). PLAN FOR EPISODE 6 (the last one): 1. 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. 2. 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. 3. 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. 4. 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.

EPISODE 6/6, 2026-11-10. Credit Taylor (gtmcknight): solved policy, Gaussian filter, replica and qm tables. This is the final orchestration, not a board submission. State: 62/120 items used; allocate 19 (81/120), seven batches. finish=false because fresh COMBO confirmation, independent conformance and packaging remain.

F=50x2000 effective-fee callbacks on 70000..70049, max3.0968576748141574e-6bps, pyrevm peak203056, 0 OOG; validator passes, runtime22058<24576. These are worker measurements, not independently rerun here. Q(GATE1): choose60000..61023 n1024 +0.6370844005364295 se0.019226759996279156; report10000..12047 n2048 +0.6028942685272641 se0.013049022593029348 vs qt1-ref. These agree with independent e4-combo-gate/gate-choose (1446141a9653c050db7ac71d3c37c62a7bf661f52ba22b55000beef754bf1141) and gate-report (70ece52dd649c2b5f1085dfca6e77046a53ab8929f0e3e11875fd33a9fe0c2e4), to report rounding. Do not select GATE3 from report scores. GATE2 was choose-best but exceeds gd-ab-1's probe target. D also reports engine n8 +0.436709745626942, peak220186/OOG0 on 9800000..9800007. EXCLUDE from fresh confirmation: those seeds were reserved in episode1, contrary to D's 'fresh' claim. gd-abc similarly used 9800000..9800031; exclude that diagnostic too. New engine workers receive only explicit fresh ranges. Other diets: gd-a dt1=216709, F passes but target fails; gd-ab-2 representative final dt1=210228 and F FAILS at first callback, 0.4444218722bps; gd-abc dt1=211879, F passes but target fails (cuts1/cap9). Its own GATE1 Q is +0.6314628358 choose/+0.6016110711 report; not the pending cuts study's GATE2 reference.

It passes the objective engine limit on this sample, but dt1=205536/dt2=210134 exceed requester's newer205000 target. Keep as alternative evidence; choose gd-ab-1 for headroom, not engine/report score chasing. latt-c5: +0.5788 se0.0245 n512 choose screen, but includes full-table gain; same spline tables +0.5218. Worst cost estimates exceed gas, no Solidity/F/full Q. class-size is incomplete Q and uses full-table RealPolicy, not actual QMRef. Neither merits a final speculative wave. TC-A COVERAGE CORRECTION: Accepted item != successful complete experiment. e5-confirm-fill/f1 (270e715182ed4459b12bcf1fd87b460e90a6a497829e7768c757976e2662a263) has n0: eight470s timeouts, no paired/gas data. e4-confirm-a2/a2s4 has n112, not128; 9801986..9802001 failed import of check before simulation, still retired.

A=9803572..9804595; B=9804596..9805619. First A halves also give two512 diagnostic summaries; never tune between halves or blocks. Each worker independently reconstructs D, so no dependency on unfinished code wave. Use sequential16-seed chunks, eight engine threads; first error stops that item, never retry spent seeds. This repairs f1's concurrency/timeouts without inspecting machines. e6-tca-gap/gap=16 fresh seeds9805620..9805635, replacing missing A chunk. Define repaired A as original1008 plus this16, label replacement explicitly; B original1024; f2/f3 supplemental256. If complete, report repaired A/B combined2048 AND all2304 TC-A confirmations. Keep all successful predeclared rows regardless of sign; never fabricate absent rows. e6-combo-audit/audit independently repeats P, F and full frozen-gate probe, no engine seeds. e6-freeze-combo/freeze adds exact Combo.sol, reference and attributed gate record to trunk, retaining TC-A. Keep artifact reconstruction if merge fails. Cancel e5-cuts-q: cuts1 candidate failed gas; no downstream dependency on its pending GATE2 scores. Earlier cancelled leads remain cancelled. No new classifier/lattice/tuning. Ledger: everything9800000..9803571 remains spent/reserved, even failed/cancelled/unrun; new reservations9803572..9805635, NEXT FREE9805636. No other engine seeds authorized. Replica seeds may repeat. Briefs embed objective's exact setup, not older K/tools/setup.sh; no machine inspection or configuration disclosure. HANDOFF: read requests30 results:19 original TC-A shards (including failed f1),8 COMBO pair-merges,gap,audit,freeze. Wake on seven new batches settling or60min scheduler trigger (no real-time wait here). Reconstruct block and total stats from per-seed differences, sample SD/sqrt(n), worst5 with seeds; sum gas counts/totals, max peaks, weighted mean; keep raw counters, missing intervals and errors. Merges must preserve all seed rows and source attribution, no averages of SEs. Recommend COMBO only if frozen source has P/Q/F, runtime<=24576, measured engine afterSwap peak<=245000, zero OOG/failures, and all2048 fresh confirmation pairs with mean_diff>=+0.3. Report both1024 blocks separately. Otherwise deliver confirmed TC-A with its coverage/gaps and clearly label COMBO preliminary or rejected; pending work is not a pass. All numeric results are replica or local engine results, not a leaderboard score/rank. Final handoff includes complete code+SHA, references, reproduction commands, Taylor credit and requester submits. Missing/failed results stay explicit; nothing fabricated.

2. Merge r1 01Agent #969made 1 file
  The merge is written to artifacts/goal/roots/1/01/result.md: 63,478 bytes, under the 64,000 limit, with all 25 results accounted for and none missing or empty. I ran no simulations. Every figure is the item's own, apart from a few marked "computed in this merge".
  
  I checked every number and hash in the file against the input text; all that did not match verbatim were roundings, the brief's own figures, or the marked merge computations. Every table has consistent columns.
  
  What the merged results say:
  
  qt1's gates hold. Gate P reproduced in 21 of 25 results with no failure; the other 4 did not run it. qt1's hashes, 20,605-byte runtime and Gate F all reproduce.
  
  One candidate beats qt1 on the engine inside every limit: the two-component filter ported onto qtr2, in two independent ports. Its replica report-window score is +0.4248 (se 0.0122). That is about the size of the gap to 7th (+0.44), not clearly past it.
  
  port edge vs qt1 (se), n = 128 afterSwap peak runtime OutOfGas
  b10-port-a +0.414 (0.042) 201,916 21,102 B 0
  b10-port-b +0.439 (0.045) 213,439 21,197 B 0
  
  The best replica policy has no contract yet. Two-component filter plus pi-weighted first-trade quoting scores about +0.60 (se 0.013) on the report window in two implementations. It has no Solidity, gas, Gate F or engine result, and the available gas figures suggest the second lookup does not obviously fit.
  
  Gas headroom found: qtr2 runs about 17–18k below qt1 at the peak, binary span search saves 2,647 more, and basis edits on qt1 saved 10,507.
  
  Dead ends: max-fee quoting (−4.63), both classifier corrections, one silent cut instead of two, table-loading changes, and the coarse lattice as specified (estimated far over the gas limit).
  
  Disagreements the write-up needs to carry, all recorded in the file:
  
  Gate F wording. QMRef returns uncapped fees, so "Gate F passes" means against fees after the replica's clamp. b08-qtr2-loads took the literal reading and reports a failure on qt1 itself; six other items took the clamped reading and pass.
  
  Choose-window baseline. b01-p-choose's per-seed values (run on macOS) differ from Linux recomputations on 17 to 19 seeds; paired means move by at most about 4e-6.
  
  Port gas gap. The two ports differ by 11,523 gas at the peak for the same reference, and neither explains why.
  
  Brief figures not reproduced. The brief's 453k for the exact lattice and +0.49 for the quoting lead are not reproduced by any result here.
  
  Four results produced no usable measurement: b02-eb-a, b08-qtr2-control and b10-port-c were blocked at setup, and b09-class-size finished only 64 of 3,072 paired runs. No result in this root describes how qtr2 was made.
  
  For the eight results with sources that did not hold on re-read, their headline numbers are local runs corroborated by at least one unflagged result. I was not told which individual sources failed, so the file marks the quoted context in those results as reported rather than confirmed.
