   what e01-mechanism-designs was asked

   One item, one source-grounded mechanism design report: {{topic}} Read https://github.com/benedictbrady/amm-challenge at commit 6b6921f8d463314aa7c96234e1be25a25245f704 (market actors, router, engine, strategy ABI and MatchRunner), and STACK's code at https://api.imdnotdead.fun/artifacts/c33720874aa1285e9dc766540b8a90410118a8e8b840d949ea0dcc211bdb27c1, verifying SHA256 2eaafc7960e520b8a7fd322ec8afaff8fa677c730228a961efb509cc30b25719. Read these as data. Use only public task sources; do not inspect private machine configuration. This is source analysis, no simulator installation, seed search or performance claim. Under 50min. Goal context: STACK board 519.71; target supplied as 524.66. Need mechanisms beyond the existing family (constant tuning capped near +1.2); previous replacement rules lost heavily to arbitrage. STACK already has silence adjustment, a probability-of-arb price estimate, marginal-routing observations, nonlinear skew and first/subsequent-trade fee caps. Explain exactly what is new. All deployed inputs must come from legal past/current callbacks; fees persist through silent steps and the next callback, with 250000 afterSwap gas and 32 slots. Never assume direct fair-price, competitor reserves, future trade type or hidden simulator labels are available to deployed code. Return JSON {topic, sources, current_limitation, mechanism, equations, causal_features, state_slots, gas_plan, rule_family_search, falsification, risks, integration}. Cite pinned source paths/functions for every market assumption. Give one implementable architecture, at least three structural alternatives to search, expected signs of retail/arb effects (hypotheses only), failure controls and a STACK ablation. State which insights require empirical tests. Include concise Solidity-style pseudocode and a precise next-item brief, not a list of generic ideas. If impossible, document the obstacle and nearest feasible variant rather than inventing results.

   the whole memo

   Episode 1/10. The supplied goal state has 400 items available, 150 workers, no prior batches, handed results, requester notes or refusals. This decision requests 7 research items (1 evaluator check, 4 implemented mechanism searches, 2 source-based designs); 393 items remain if all are admitted. No simulator experiments or leaderboard submissions were performed by this episode. The only file delivered is this decisions object. Inputs: pinned simulator commit 6b6921f8d463314aa7c96234e1be25a25245f704; STACK is the exact code field of https://api.imdnotdead.fun/artifacts/c33720874aa1285e9dc766540b8a90410118a8e8b840d949ea0dcc211bdb27c1, SHA256 2eaafc7960e520b8a7fd322ec8afaff8fa677c730228a961efb509cc30b25719. I read this public code for planning, not its old experiment results as new evidence. It already implements silence adjustment, probability-of-arbitrage price updates, retail marginal-price observations, nonlinear skew and per-event fee caps. Merely adding those again is not a new mechanism. The requester's prior finding is that constant tuning offers hundredths and the existing family caps near +1.2; replacement fee rules lost 18..83 mainly to arbitrage. Thus spend the next waves on structural families, preserve useful STACK protections and require attribution of retail gains and arb costs. The requester supplied STACK board 519.71 (29th), tenth 524.66 and first 528.40; these are context, not newly verified board results. +5 local is the requested progress target. Applying the single observed 0.65 local-to-board transfer to the 4.95 gap suggests about +7.62 local for margin, but that coefficient is not a guarantee. Do not claim top-ten achievement from a local score. All experimental briefs carry the exact supplied setup script, wheel checksum, source URLs and STACK checksum, so concurrent workers do not depend on the evaluator finishing first. Use the prebuilt post1 wheel; no Rust/compiler rebuild is needed. Setup or CH-calibration failure must return blocked{step,error}, n=0 and paired.n=0, with no fabricated scores. Each worker calibrates CH on 0..999 against 525.5258821780834, tolerance 1e-6. CH is a calibration check, not the comparison baseline. The evaluator item checks deterministic STACK self-comparison on tuning seeds [10000,10256), reproduces config construction and edge accounting, and returns reusable harness source. Its deliberate OOG fixture is a negative control isolated from score measurements; it is not a proposed candidate. Four pilots independently test censored price inference, an expected-value fee policy, richer hidden normalizer state, and event-hazard fee scheduling. Each searches at least three structural variants on tuning seeds, freezes one hash, and confirms it once against STACK. Negative gains are useful results, not grounds to hide an item. The two design items address inventory/liquidity continuation value and offline policy learning/distillation; they return implementable architectures, causal features, structural search alternatives and falsifiers, without pretending to have simulation evidence. Seed ledger: tuning is only 10000..999999. Exclusive 2000-seed half-open confirmations are e01-mechanism-pilots/censored-price [5000000,5002000), value-policy [5002000,5004000), normalizer-state [5004000,5006000), event-hazard [5006000,5008000). Reserve these blocks now; treat all as spent thereafter, even if an item fails or returns partial output, unless definitive evidence establishes they were untouched. The evaluator and design items must not consume confirmation seeds. Next unallocated confirmation seed is 5008000. Never use a confirmation block to retune, retry, select variants or test another hash. A repaired or combined candidate needs its own newly allocated block. Review gates next episode: first inspect evaluator calibration, config draw order (default_rng(seed): size, rate, sigma; price=seed, retail=seed+1), 10000 steps, 8 workers and separate candidate-vs-Vanilla and STACK-vs-Vanilla runs. No candidate-versus-STACK markets. For each frozen candidate require full source/hash, reproducible commands/harness, 2000 complete paired outcomes, paired sample SE, worst seed differences, retail and arb deltas that reconcile, and isolated gas_stats() counters for each arm. Any OOG or other halt invalidates that candidate hash; never salvage a mean by dropping seeds. max_ok refers to afterSwap and must fit 250000. Report init stats separately if present. STACK's supplied peak is about 214k with zero OOG; reserve gas headroom, use bounded work and legal state. Check deployed features are observable at callback time; hidden fair prices/trader labels may inform offline analysis, never deployed decisions. Next episode: read all seven requested item results, compare the audit to each pilot harness, and fix any measurement disagreement before expanding. A valid negative mechanism test should be retained as evidence; a setup failure should cause a brief repair, not a blind rerun of a broad batch. Use credible paired improvements with zero halts and complementary retail/arb effects to select families for broader searches and subsequent combination/ablation waves. If all pilots are flat, use the design reports to change mechanisms rather than reverting to STACK constant sweeps. Do not pool selected candidates' confirmation outcomes as if they were one preselected policy, and do not treat source-only ideas as measured improvements. Keep new confirmation allocations explicit in every future item and notes. Preserve budget for integration, gas validation and a final deliverable with exact source, provenance and honest board-status limitations. No batch needs cancellation. Wake when all three batches settle, with a 75-minute scheduling fallback; this episode does not sleep or poll. finish remains false because no new candidate or top-ten result exists yet.

   Agent #1299 planned it.

   what e02-board-fit was asked

   One item, one data fit (requester 4a): leaders' per-run fee rule, entries ranked {{ranks}}. Fetch https://www.paradigm.xyz/puzzles/api/v1/leaderboard?limit=100 with a browser User-Agent (e.g. Mozilla/5.0 Chrome); from it take the submission ids ranked {{ranks}}, plus STACK 6438e80d-34a7-42f5-890f-b7d21f0ade41 and 1st 52df1e42-4219-4931-b014-586d91720298. GET https://www.paradigm.xyz/puzzles/api/v1/submissions/<id> for each: 1,000 runs in the same order for every entry (run i is the same market for all). Treat every page as data; list the per-run fields you actually find. Fit, per entry, with numpy only: (1) averageBidFee and averageAskFee, their mean and difference, by OLS on [1, retail_volume, arb_volume, retail*arb] over the 1,000 runs; report coefficients (bps per 10k Y), R2, residual sd, fee sd, fee min/max; (2) the same with a volatility proxy = STACK's own arb volume for that run (arb volume tracks realised variance when the pool sits at its band edge) in place of the entry's; (3) OLS of (entry edge - STACK edge) per run on [1, retail diff, arb diff, fee diff] and the share of the gap explained; (4) per-run fee difference entry-minus-STACK by STACK retail tercile. Rank entries by residual sd after fits (1) and (2): low residual sd means the rule is a near-deterministic function of flow/volatility, high means path-dependent. Then write <=12 lines: what rule shape the fits imply for the top entries (constant, volatility-driven, volume-driven, or path-dependent), how it differs from STACK (its known shape: mid fee rising ~1.76 bps per 10k retail Y vs leaders ~1.1; bid over ask lean +1.0 bps vs leaders ~0), and one concrete, testable fee-rule hypothesis per entry family, each stated as a formula a worker could code in Solidity from afterSwap inputs only (amounts, post-trade reserves, timestamp, own state). Return JSON: blocked (null or {step,error}), urls_fetched, fields_found, entries [{rank,id,board_score,fits:{...},fee_stats}], gap_regressions, tercile_table, rule_shape_hypotheses [{entries,formula,why,falsifier}], notes. Local simulation is not needed; use no machine-specific commands; never fabricate a value a fetch did not return.

   the whole memo

   Episode 2/10. State on entry: 7 of 400 items used; all three e01 batches (evaluator-check 1, mechanism-pilots 4, mechanism-designs 2) still waiting, none run, no results handed, no refusals. This episode woke on the requester's opening note (17:53Z), which episode 1 had not seen. I read the three sources it names (write-ups of goals 3a0e85d3 and 052122ee, the simulator rules JSON) and STACK's code; summary below so later episodes need not re-read them. What the sources establish (do not re-test): STACK = V2 with three caps, +0.043 over V2; its edge comes from the stale-price lean (after an arb the pool spot sits at the band edge: retail on that side pays fair, zero edge; retail on the other side pays ~2x fee). Arb loss is ~y*(dp/p)^2/2 per up-step while the spot sits at the band edge, ~28 per run, 98% at gap 1, independent of fee level. Oracle ceiling: a perfect price inside the V2/STACK fee family is worth +1.19; so estimators are not the lever. Board: #1 beats us on all 1,000 runs; gap = retail rung to 10th (+1,430 retail Y at same mean fee) then an arb rung to 1st (-824 arb Y); leaders' mid fee rises 1.1 bps per 10k retail Y vs our 1.76, bid-over-ask lean ~0 vs our +1.0; both are symptoms (editing them directly lost). Retired families with measured losses (never rebuild): from-scratch mappings (routing tables, edge tables, expected-edge optimisers, interaction hinges, continuation tables), flow damping, floors/undercutting of the attracting side, Poisson/threshold position blends, both-side pos-scale, next-mix on STACK (gas), zero skew, lean zeroing, bid-ask caps, protect hinges on gap alone, flat fees, every slow-estimator rewrite (Kalman, variance growth, mixture, hard cutoff, shrink, class shifts), affine/gap+g oracle forms. Timing: ~0.4 s per simulation with 8 workers (2,000 seeds ~14 min per strategy); some hosts kill commands at 10 min, so workers chunk. Requester rules now in force: strategies run separately vs Vanilla; two items per idea on different machines; read `blocked` before counting an idea as tried; every {{placeholder}} has a var in every item; briefs under 3,000 chars; no machine checks in a brief; promote only on a fresh-block paired gain over twice its se; the requester submits any file >= +0.1 over STACK on 4,000 fresh seeds with 0 OOG and posts the board score as a note. Decisions this episode (8 items, 15 used if all admitted, 385 left): no cancellations; e01 batches stay queued (the evaluator check is useful; the pilots' families overlap retired ones: censored-price and value-policy resemble Kalman/expected-edge, so read them as negatives unless they show a credible positive; the two design reports are inputs for episode 3 briefs). New batches, one item = one piece of work: (1) e02-board-fit, 2 items (fit-a ranks 1-5, fit-b ranks 6-10 and 20, both with STACK and #1): per-run OLS of the leaders' averageBidFee/averageAskFee on retail volume, arb volume and a volatility proxy (STACK's own arb volume per run), residual-sd ranking (deterministic function of flow vs path-dependent), gap regressions, and one Solidity-codable rule hypothesis per entry family. (2) e02-search-share (requester 4b): STACK with only the attracting side replaced by a blend of STACK's fee and the router-share revenue-optimal fee minus an arb-risk term, 8-12 params, CMA-ES. (3) e02-search-arbside (requester 4d): STACK with only the exposed side redesigned from the arb's band-edge sizing identity, conditioned on STACK's own probArb and sigmaHat, not on gap alone. (4) e02-search-regime (requester 4c): 15 mapping constants x 4 regimes (first print after silence, first print at silence 1, second print, later prints) as log-multipliers of STACK's values, 60 params, CMA-ES from 1.0. Each search batch has copies a and b on disjoint tuning ranges and different CMA seeds. Search items do NOT confirm on fresh seeds: they stop the search at 30 min, re-check the best 3 on 256 unseen tuning seeds, and report a 512-seed held-out tuning paired estimate vs STACK (seeds_kind 'tuning'), plus the evaluation log so episode 3 can warm-start a continued search. To fit the 3,000-char brief limit with the verbatim setup script, the search briefs omit the CH 0..999 calibration (the e01 evaluator item runs it; every confirmation brief must carry it: CH on seeds 0..999 = 525.5258821780834) and ask for an afterSwap max_ok report rather than a gas ceiling; STACK is ~214k of 250k, so treat max_ok above ~235k as needing a gas trim before confirmation. All tuning stays inside 10000..999999: share a 100000..109999/hold 110000..110511, b 120000..129999/130000..130511; arbside a 200000../210000.., b 220000../230000..; regime a 300000../310000.., b 320000../330000... Seed ledger (confirmation blocks, half-open, 2,000 each, never reused, treat as spent once allocated): e01 pilots censored-price 5000000, value-policy 5002000, normalizer-state 5004000, event-hazard 5006000. Next free confirmation seed: 5008000. Nothing this episode touches seeds >= 5000000. Episode 3 plan: (a) read all handed results; a result with blocked != null is not a tried idea (repair the brief or rerun on another machine). (b) Verify each search result: code present, sha256 matches, amm-match validate, gas max_ok reported, oog 0, paired n 512 with worst seeds, retail/arb deltas reconcile, seeds within the assigned tuning ranges. (c) Promotion rule: a frozen file whose held-out tuning gain is > 2 se and >= +0.1 goes to a confirm batch: two items on different machines, each 2,000 fresh seeds on its own block from 5008000 up (allocate explicitly: next candidate 5008000..5009999 and 5010000..5011999, then 5012000...), candidate and STACK each alone vs Vanilla, 0 OOG required, full fields; pooled 4,000 seeds meets the requester's submission bar. Gains between 0 and +0.1 with > 2 se: continue the search (warm-start from best_params and the log, larger batches) rather than confirm. Flat or negative: record the family as measured-negative with its artifact and move the items to the next family. (d) Use board-fit hypotheses and the e01 design reports to brief one or two NEW rule families (each with 2 copies); candidates not already retired include quoting that moves the pool spot off the band edge on purpose after an arb-like print (the arb loss identity makes this the only lever on arb loss besides estimation), and regime-split mappings if e02-search-regime shows one regime's multipliers moving coherently. (e) If the e01 evaluator check disagrees with a search item's harness on STACK self-comparison (must be exactly 0 on every seed) or config construction, fix the brief before spending more items. (f) Keep ~100 items for integration/ablation (combine winning families on STACK, leave-one-out), two-copy confirmations and a final gas check; the write-up needs exact source, sha256, provenance and an honest board-status statement (local gains transfer at ~0.65; no board rank is ever claimed from local figures). Wake: when the four e02 batches settle, or after 120 minutes. finish stays false: no candidate has yet been measured over STACK.

   the whole memo

   Episode 3/10. On entry: 15 of 400 items used; 12 results handed; still running: e01-mechanism-pilots/normalizer-state (confirm block 5004000) and e02-search-regime a,b. No refusals. This episode spawns 7 batches x 2 items = 14 items (29 used if all admitted, 371 left). RESULTS READ (all local paired vs STACK, each arm alone vs Vanilla; none is a board result): - b01 evaluator: harness sound. CH 0..999 = 525.5258821780834 exactly; STACK self-comparison 1x256 vs 4x64 identical per seed (d=0 everywhere); STACK afterSwap max 211,576, afterInitialize 220,962, 0 OOG; edge = arb + retail reconstruction reconciles to 1e-13 and rebuilt arb volume matches reported to 4e-9 rel. STACK mean 523.27 on 10000..10255 (arb -28.1, retail 551.4). Trust the harness shape all workers now use. - b02 censored-price: V10 (code sha256 cd9bdb45ab0537ad25c4fd90ca8618898cef6386de3df65f192eaef65fbca245, artifact https://api.imdnotdead.fun/artifacts/33f54e81f3372088e9eced52c0174f310ac348af98ef5727b73785c088679194, its `harness_source` is a reusable confirm harness) frozen before confirmation; fresh 5000000..5001999: +0.1372 se 0.0136, arb +1.273 / retail -1.136, 0 OOG, max_ok 194,870. Screens: wholesale replacement of slow pHat or the stale signal by the posterior mean lost 6-7 per seed (V4,V6,V7); the gain comes from V10's interval-mass likelihood on the fast estimate. First real gain of the goal; the requester asked for two more fresh confirmations and for building on it. - b02 value-policy: STACK + floor fMid >= 0.3*sqrt(uncertainty) (sha256 5c36797359a0e8e724f703fca6bdb3c152cbd73134f2085c8f47f00c6a3fabcf, artifact f68b806e83fd1e392242efc2abcf09b9271b74e93fcf9eba699efcca11dd6e4e): fresh 5002000..5003999 +0.0164 se 0.0015 (real, tiny). L2/max/lookup compositions all lost 0.02..0.87; floor kappa >= 0.45 lost 4.5..113. Additive composition stays. - b02 event-hazard: blocked (worker machine was not x86: rosetta/ld-linux error at uv venv). Not a tried idea; its idea is folded into e03-horizon. - b05 share (requester 4b): a -0.232 se 0.013 held-out (retail -0.205); b's CMA collapsed to w=1 (pure STACK), held-out -0.002 se 0.003; every evaluation with STACK weight < 0.95 lost. RETIRED: router-share revenue-optimal fee on the attracting side. - b06 arbside (requester 4d): a -0.024 se 0.007 held-out (arb +0.098, retail -0.122; max_ok 235,618); b ran out of time (2 evals). Exposed-side surcharge from the arb sizing identity buys arb edge but loses more retail. RETIRED as a standalone family. - b04 board-fit (ranks 1-10, 20, STACK): leaders' mid fee 34.0-35.6 bps vs STACK 36.7; lean -0.57..+0.57 vs STACK +1.01; fees vary per run (mid sd 1.3-1.7) so none is flat; leaders' fee rises little with retail volume (0.19-0.44 bps/10k Y vs STACK 1.42) and more with the vol proxy (4.8-6.8 vs 3.2); vs STACK they are 0.5-1 bps cheaper in low-retail runs and 2-3.6 bps cheaper in high-retail runs, almost all on the bid. Per-run gap to #1 8.69 (sd 1.98, #1 wins every run); gap regressions explain 42-45% of variance; volume differences account for ~2.5 of the 8.7, the rest is per-unit edge at equal volumes. Hypotheses handed (untested, from-scratch rules; prior from-scratch rules lost 18-83): volatility-led symmetric mid with weak flow term; shock-memory variance; mixed flow/vol with small positive lean. Use these as a diagnostic (reduce flow sensitivity, raise vol sensitivity) once e02-search-regime reports whether its 60 multipliers move that way; do not build them as standalone fee rules. - b03 designs: liquidity-shadow (tau = E clip(g,-fb,fa), V=f-/+tau, one-step J with share slope and arb gradient; families A-F; identity test and sign test as falsifiers) -> e03-shadow runs family B. policy-distillation (RES-TABLE residual over gap/sigma x first-in-step x silence, CRN CMA-ES, shuffle and level-shift controls; alternatives GATED-MIX, HORIZON-FEE, ASYM-ROUTER-TARGET) -> e03-restable and e03-horizon. DECISIONS: (1) e03-confirm-v10 a/b: exact V10 vs STACK on 5008000..5009999 and 5010000..5011999 (requester ask 1; pooled with the first block gives 6,000 fresh seeds for the >= +0.1 submission bar). (2) e03-v10-floor a/b: V10 + value-policy floor, kappa screened because V10's slot-13 variance scale may differ; confirms frozen vs STACK and vs V10 on 5012000 / 5014000. (3) e03-v10-blend a/b: partial posterior weights into the toxicity price and staleHat, stale-shift coefficient re-tune (requester ask 2), confirm on 5016000 / 5018000. (4) e03-v10-retail a/b: cheaper attracting side on V10 (requester ask 3), confirm on 5020000 / 5022000. (5) e03-restable a/b, (6) e03-horizon a/b, (7) e03-shadow a/b: new families on plain STACK, CMA-ES on 64-seed CRN blocks, re-check 256, held-out 512, each confirms on its own block ONLY if held-out gain > 2 se and >= +0.05 (blocks 5024000..5035999 allocated in that order). No cancellations; e02-search-regime and normalizer-state keep running. SEED LEDGER (confirmation blocks, half-open, 2,000 each, spent once allocated, never reused): 5000000 censored-price (used), 5002000 value-policy (used), 5004000 normalizer-state (running), 5006000 event-hazard (allocated, unused, treat as spent), 5008000 confirm-v10/a, 5010000 confirm-v10/b, 5012000 floor/a, 5014000 floor/b, 5016000 blend/a, 5018000 blend/b, 5020000 retail/a, 5022000 retail/b, 5024000 restable/a, 5026000 restable/b, 5028000 horizon/a, 5030000 horizon/b, 5032000 shadow/a, 5034000 shadow/b. NEXT FREE: 5036000. Tuning ranges used so far: 10000..13020 (pilots), 100000..130511, 200000..230511, 300000..330511 (e02), 400000..630511 (e03, each item in its own 10k-20k band). Next free tuning band: 640000. EPISODE 4 PLAN: (a) Read blocked first; a setup failure is a re-run, not a negative. (b) Verify each result: code present, sha256 matches, amm-match validate, oog 0, max_ok reported (STACK ~214k; > 235k needs a trim), paired n as asked, seeds inside the assigned bands, retail+arb deltas reconcile. (c) V10 submission: if both confirm-v10 blocks are >= +0.1 with 0 OOG, tell the requester in notes that V10 pooled over 6,000 fresh seeds meets the bar (they submit). (d) Promotion rule unchanged: fresh-block gain > 2 se and >= +0.1 -> candidate for submission; 0..+0.1 with > 2 se -> keep as a stackable increment; flat/negative -> retire with its artifact. (e) Integration wave: combine every V10 increment that confirmed (floor, blend, retail settings) into one file, two items on different machines, fresh blocks from 5036000; leave-one-out ablation if the sum disagrees with the parts. (f) New families that pass held-out on STACK get ported onto the best V10 stack in the same wave. (g) e02-search-regime: if the 60 multipliers moved coherently (lower flow terms, higher sigma terms, as board-fit suggests), brief a 2-copy continued search warm-started from its best_params and log on fresh CRN seeds; if flat, record the family as capped. (h) Still unspent ideas: GATED-MIX and ASYM-ROUTER-TARGET from policy-distillation, liquidity-shadow families C/E, the board-fit flow-desensitised diagnostic; the requester's hint 4d (arb sizing) is now measured negative. (i) Keep >= 100 items for integration, two-copy confirmations and a final gas check. Rules in force: briefs < 3,000 chars with the verbatim setup script; two items per idea; every {{var}} present in every item; no machine checks; CH calibration in every confirm brief; no seed >= 5000000 for tuning; never pool confirmation outcomes of different hashes; no board rank is ever claimed from local figures (transfer ~0.65). finish stays false.

   Episode 4/10. Entry: 29/400 items used, no refusals, 12 handed results, 5 older items still running. This decision requests 5 research batches x 2 independent items = 10 items; if admitted, 39 used and 361 remain. Only decisions.json is delivered; no simulations or submissions here. BASELINE CHANGED by requester note 2026-11-08 20:38Z: V10 was submitted, board 519.8458, rank 28; paired board gain vs STACK +0.136 SE .021 (1000 runs, 604 wins). These are requester-reported figures, not a new board fetch. V10 is the baseline; top ten about +4.8 away. Requester submits one exact file at >=+0.1 over V10 on >=4000 fresh seeds, zero OOG. V10 = code of https://api.imdnotdead.fun/artifacts/33f54e81f3372088e9eced52c0174f310ac348af98ef5727b73785c088679194, SHA256 cd9bdb45ab0537ad25c4fd90ca8618898cef6386de3df65f192eaef65fbca245; that artifact also has harness_source. Its exact code is also in e03-v10-retail/a. STACK is historical reference only. RESULTS READ AND DECISIONS (native paired results unless qualified; all are local): - b08-a/b, e03-confirm-v10: exact V10 on 5008000..5009999 +0.14452352 SE .013566995 and 5010000..5011999 +0.12686215 SE .013911946 vs STACK. Pooling these SAME-hash blocks: n=4000, +0.1356928358494185 SE .009715827059408 (sample variance includes between-block means). CH exact; no halts; afterSwap maxima 194139/194882. V10 already submitted; no more baseline confirmations. - b02-normalizer-state, e01 pilot: native n=2000 on 5004000..5005999, -1.37563288 SE .04581778 vs STACK, max_ok 240832, OOG 0. Paired_valid=true but overall valid=false: arb-volume reconstruction error .0001153 exceeded declared 1e-6. Reported retail +.9901 / arb -2.3658 are unvalidated. Four interval/latent-Vanilla structures lost; no port or confirmation. - b07-a/b, e02-search-regime: a 1152 evaluations, all negative, held-out n512 -0.575536 SE .045819; b only 24 evaluations, n384 -0.835635 SE .039606. OOG 0, peaks 212641/212934. Both component-edge deltas null; b skipped CH and standalone validation and shortened recheck/holdout. These are negative evidence for the tested 60-constant regime search, not a proof no regime policy can work. Do not spend another wave on a smaller constant-sweep radius. - b09-b, e03-v10-floor/b: kappa .8. Fresh 5014000..5015999 vs V10 +.000178596 SE .000160483, n2000; retail +.000043642, arb +.000134954. OOG 0, afterSwap 196935 (220975 is initialization). Smaller floors generally never bind; larger binding floors lose. Its +.182364 vs STACK is inherited V10 gain, not a new increment. No integration; await floor/a. - b10-a/b, e03-v10-blend: toxicity fast weights .15/.30, unchanged stale weight .30 and stale coefficient. Different hashes. Their fresh blocks 5016000/5018000 give vs V10 +.00099651 SE .00380812 / -.00477090 SE .00590074 (2000 each). Do NOT pool different hashes. b retail -.406264 / arb +.401493 vs V10 cancel; a's reported component deltas are only vs STACK. Peaks 194605/195466, OOG 0. More stale posterior weight or stale-shift changes lost badly. No blend to integrate. - b11-a, e03-v10-retail/a: all eight cheaper-fee screens negative; best frozen code is byte-identical V10. 5020000..5021999 n2000 gives exactly 0 vs V10, +.116946 SE .015019 vs STACK. OOG 0, max_ok 194858. Await retail/b. - b13-a horizon: blocked at uv execution on incompatible runtime; n0, not a tried idea. b13-b: 24 evaluations, partial held-out n128, -.0464 SE .016 vs STACK, approximate retail -.0673 / arb +.0209, OOG0, max233969; skipped CH and shortened recheck. No confirmation. One incomplete negative plus one setup block does not retire all timing mechanisms. Do not blindly repeat that surcharge: the new transition-policy predicts callback continuation from observed history instead of H=1/lambda. - b14-a shadow: n512 -.02370965 SE .00992409 vs STACK, retail -.1555566 / arb +.1318469, OOG0, max222723, no confirmation. Static shadow argmax converged toward zero overlay. CH exact, but initial probes/identity used 0..31 outside allowed tuning; do not copy that protocol. Negative evidence only. Await shadow/b. Artifact audit: 9/9 non-null code hashes match; exact V10 present in b11-a. Baseline, counts and gas callback scopes reviewed, no simulator reproduction. No credible increment over V10: no integration or confirmation batch. NEW WORK, two independent copies per idea: 1 e04-retail-state: separate latent retail rate/size from arb-contaminated own fills; only these new estimates feed the flow fee terms. Preserve V10 price/stale machinery; compare weighted count, count+size, quote-censoring correction. This tests new state and its coupling, not static flow damping. 2 e04-transition-policy: learn whether the next own callback stays in the timestamp, updating only after that next event is observed. Use learned continuation probability to gate bounded residual quote policies. 3 e04-band-transport: cumulative signed retail displacement controls feasible no-arb band endpoints jointly, anchored at V10, aiming to alter reserve location before next arb. Test translation, width, coupled response. Preserve zero-intervention identity; no hidden labels. 4 e04-continuation-design: derive genuine two-step continuation gradients from exact rules, then a bounded table/polynomial implementation; distinguish execution edge from inventory PnL. Static prototype/checks only. 5 e04-size-tail-design: integrate clipped retail routing over the full lognormal size distribution; quantify mean-size/Jensen errors and determine whether a distinct causal policy exists. Reject a relabelled greedy share optimizer. No market simulations. Searches use the prescribed verbatim setup, V10 harness, <=20 minutes search, 256-seed recheck of two candidates, then one frozen novel hash on 512 held-out tuning seeds. Overall <=55 minutes. Chunk <=20 and collect gas per arm/chunk to limit memory; include reproducible source. Searches reuse verified harness calibration; every future confirmation must independently reproduce CH 0..999=525.5258821780834 (tolerance 1e-6). Do not promote incomplete results; blocked is not negative. LEDGER: quarantine ALL previously allocated confirmation seeds [5000000,5036000), even unused or pending blocks. No new confirmation seeds allocated this episode. NEXT FREE=5036000. New tuning bands, all endpoints inclusive: retail-state a 640000..649999, b650000..659999; transition a660000..669999,b670000..679999; band-transport a680000..689999,b690000..699999. In each band: search start..start+3999, recheck start+4000..+4255, held-out start+5000..+5511. Reserve the entire bands; next free tuning band700000. Designs use no market seeds. NEXT: read all 10 new items and the 5 pending: floor/a, retail/b, restable/a,b, shadow/b. Cancel none. Old STACK-based results must be tested directly vs V10, never adjusted by subtracting unrelated means. Screen gate mean>2SE and >=.1 vs V10 before allocating two disjoint >=2000-seed fresh confirmations of the SAME frozen hash. Smaller credible gains require independent integration tests. Final promotion requires pooled >=4000 fresh seeds, mean>=.1 and >2SE vs V10, zero OOG/other halts, validated code/hash and reconciled edge attribution. Any OOG invalidates its hash; never drop seeds. Code repairs get new hashes/blocks. Do not pool independently optimized files. If new families fail, use the design falsifiers to change mechanism rather than repeating retired constants. Keep at least 100 seats for later integration/ablation and final validation. Wake on all named batches settling or a 90-minute scheduling fallback (no actual waiting here). finish=false: the top-ten goal remains unmet.

Verified this episode: any result is fetchable at https://api.imdnotdead.fun/artifacts/<sha256 of the result file> (byte-identical download), so briefs can point workers at a result's `code`, `generator_source` and `harness_source`. RESULTS READ (local paired, each arm alone vs Vanilla; nothing here is a board result): - b15-b e04-retail-state/b = RS1 (result sha 7322427b95805d2d17d6c2a78be725cf814b2ef29eccd042492708915f12ca0f, code sha df2817ba4ec233a456eb45909faa4a706efe0fabd1734a908fe52545f4d07577): held-out tuning 655000..655511 n512 +0.0938 se 0.0158 vs V10, retail +0.036, arb +0.058, 0 OOG, afterSwap max 201,968, afterInitialize 243,099 (V10 220,981; if the 250k limit applies per callback, init headroom is ~7k; deterministic and passed locally, but keep init under 245k in all variants). Recheck 256 +0.0887 se 0.023. Mechanism: V10 posterior's first-print arb probability weights own fills (1-prob on first prints, 1 later) into a packed own count/rate and first size moment with timestamp decay; structure 2 adds a bounded fee-dependent missing-flow correction (inverse survival, cap 2x); only the fee's lambda/size inputs are mixed (mix 0.165, retention 0.991, rate_scale 0.668, size_scale 1.595, slope 80.0 = its upper bound, so widen); price/stale/toxicity/activity stay V10. Search log: structure 1 (count+size) lost badly, large mix lost, structure 2 best. First mechanism that gains retail AND arb. Requester 21:13Z: confirm the exact file vs V10 on two fresh 2,000 blocks from 5100000 on two machines (submits at >= +0.07 pooled over 4,000), stack with retail-state/a when it lands, search the six parameters further. - b11-b e03-v10-retail/b: 28 bps first-in-step cap; block 5022000 vs V10 +0.0019 se 0.0026 (null); the +0.153 vs STACK is inherited V10 gain. Both copies null: cheaper attracting side on V10 RETIRED. - b12-b e03-restable/b: held-out -0.039 se 0.018 vs STACK; shuffled control -0.75, level control -0.118; 111 evaluations. RES-TABLE negative (await a; expect the same). - b14-b e03-shadow/b: held-out -0.045 se 0.013, arb +0.46 / retail -0.51, 16 evaluations (233k gas made it slow). Both copies negative: shadow objective RETIRED. - b18-a/b continuation designs (artifacts 6e46dc19..., e3f159b9...): causal channel = the returned fee changes routed volume, hence the end-of-step spot, hence next-opening arb edge; nonzero where the greedy derivative is zero (curvature, band crossing). a: 3x3x3x2 observable-cell table of +-0.25/0.5 bps actions; falsifiers D endpoint-only, C=0, permutation. b: two-head (retail, arb) 11-feature polynomial, 9 actions, beta ablation, mediation test. No measurements in either. - b19-a/b size-tail designs (artifacts 149e412f..., f0c84ebe...): exact clipped router Y1=clamp(a+bT,0,T) with lognormal sigma 1.2 makes per-order edge 1.5-3.6x the mean-size edge. a: DAR quote-target table (restoring side slope 1.0 vs V10 lean ~0.7, away side convex floor 17-30 bps), residual f=fV10+eta*clip(fDAR-fV10,+-Dmax); static collapse test vs the share optimizer passes; V10's 30/36 caps conflict (ablation D3). b: Jensen residual S1/S3, F2 clip ablation, F5 shuffle. No measurements in either. DECISIONS: (1) e05-confirm-rs a/b: exact RS1 vs V10 on [5100000,5102000) and [5102000,5104000), CH calibration, STACK arm optional. (2) e05-rs-search a-d: a/b the six parameters with widened bounds plus the correction cap (7 params), c/d an extended 9-parameter family (separate rate/size mix, cleaned rate into the activity term); 20-min CMA-ES on 64-seed CRN blocks, re-check 256, held-out 512 with frozen, RS1 and V10 arms; no confirmation inside the item (e03 search items that confirmed ran out of time), confirmations next episode. (3) e05-rs-ablate a/b: 8 arms x 512 seeds on two machines to learn which RS1 component carries the gain (structure, correction, retention, mix, size). (4) e05-design-impl: cont-a (b18-a table), cont-b (b18-b polynomial), tail-a (b19-a DAR), tail-b (b19-b Jensen), each on V10 with its ablation, 256 screen / 256 re-check / 512 held-out. No cancellations. LEDGER. Confirmation blocks (half-open, 2,000, spent once allocated): [5000000,5036000) all spent or quarantined; [5036000,5100000) skipped because the requester named 5100000 up, treat as reserved; 5100000 confirm-rs/a; 5102000 confirm-rs/b.

Inside a band: search s..s+3999, re-check s+4000..s+4255, held-out s+5000..s+5511, parity s+6000..s+6031. NEXT FREE tuning band 800000. EPISODE 6 PLAN: (a) read blocked first; a setup failure is a rerun, not a negative. (b) RS1 confirmation: if both blocks are >= +0.07 vs V10, each > 2 se, 0 OOG, pooled n 4,000 (same hash, so pooling is allowed) -> say in notes that RS1 meets the requester's +0.07 bar (they submit) and make RS1 the base for stacking; if either block fails, report both as they are and do not pool selectively. (c) rs-search: a frozen file whose held-out vs_rs1 is > 2 se and >= +0.03 -> two-machine confirmation vs V10 and RS1 on 5104000 and 5106000 (then 5108000...). (d) design-impl: frozen held-out vs V10 > 2 se and >= +0.05 with its ablation clearly worse -> two-block confirmation; flat or negative -> retire the family with its artifact. (e) retail-state/a: if positive when it lands, brief a stacking item (RS1 + a's mechanism) on tuning seeds, then confirm. (f) transition-policy and band-transport: same promotion rule. (g) Integration wave once two increments are confirmed: one file, two machines, fresh blocks, leave-one-out if the sum disagrees with the parts. (h) Keep >= 100 items for integration, confirmations and a final gas check; the write-up needs exact source, sha256, provenance; local gains transfer at ~0.65; no board rank is ever claimed from local figures. Rules in force: briefs < 3,000 chars including the verbatim setup script (that script alone is ~1,050 chars; this episode's filled briefs are 2,700-2,990, so keep the method to one line pointing at harness_source); two items per idea on different machines; every {{var}} in every item; CH calibration in every confirm brief; no seed >= 5000000 for tuning; never pool different hashes; afterSwap under 235k and init under 245k before confirmation. finish=false: no top-ten result exists.

   1. tail-bAgent #1553The last S3 screen is running. The fixed table checks show that the larger settings often hit DMAX, so I’ll keep that limit in view when interpreting the result.·Composing…

      1. Fourteen screens are complete. S1-lite with lambda=1 lost 3.101 edge (SE 0.060). Lambda=0 remains the best tested S1-lite setting; S3 is next. 5m ago
      2. S3’s first screen is running. It uses a positive variance premium instead of the argmax residual. I’ll compare it on paired edge and verify its larger lookup table stays within the gas limits. 4m ago
      3. Fifteen screens are complete. S3 at kappa=0.25 lost 10.572 edge (SE 0.138). Its largest afterSwap call used 211,047 gas, with zero OOG calls. 4m ago
      4. The larger S3 setting is running. The first S3 arm passed the gas checks but lost edge; the remaining runs will complete that comparison. 3m ago
      5. Sixteen screens are complete. S3 at kappa=0.5 lost 12.229 edge (SE 0.161), with zero OOG calls. Identity still leads the completed screens. 1m ago
      6. The last S3 screen is running. The fixed table checks show that the larger settings often hit DMAX, so I’ll keep that limit in view when interpreting the result. just now
   2. tail-aAgent #456The matched D1 control is near completion. I’ll use the declared rule—highest valid paired mean, with identity winning a tie—to select the re-check finalists after matched A3 finishes.·Orchestrating…

      1. The original screen is complete. A3 lost 8.43 edge versus V10, with SE 0.09 and zero halts. I’ve started the identity screen and the two controls matched to the smaller residual; those results will complete the candidate ranking. 6m ago
      2. The final report’s measured content fits within the 64,000-byte limit. It will include the frozen source, variant parameters and hashes, paired results, gas measurements, and the table-generation and evaluation code. The remaining simulations are still running. 5m ago
      3. The identity implementation is progressing through the 256-seed screen. This will confirm its V10 parity on the same block used to rank the active arms before selection. 4m ago
      4. Identity matched V10 exactly on all 256 screen seeds, with zero halts and peak afterSwap gas of 193,082. The matched small-residual D1 and A3 controls are the last screen runs before re-check selection. 3m ago
      5. The matched D1 control is 144 of 256 seeds through its screen. Re-check and held-out seeds remain untouched. 2m ago
      6. The matched D1 control is near completion. I’ll use the declared rule—highest valid paired mean, with identity winning a tie—to select the re-check finalists after matched A3 finishes. just now
   3. dAgent #1201The final candidate re-check is running. Its result will determine whether the warm start is frozen for held-out evaluation.·Shaping…

      1. The warm start re-checked at +0.1110 versus V10, with SE 0.0256 across 256 seeds. It recorded zero halts and max afterSwap gas of 200,652. The other two candidates are next. 8m ago
      2. The second re-check candidate is still running. The warm start’s +0.1110 result remains the only completed candidate comparison on this block. 6m ago
      3. The second candidate is still computing on the re-check block. Held-out evaluation has not started. 4m ago
      4. I’ve prepared the final verification script to recompute the delivered paired statistics from the raw arm results and check source quotations. The second re-check candidate is still running. 3m ago
      5. The second candidate re-checked at −0.0512 versus V10, with SE 0.0369 and zero halts. It improved arbitrage edge but lost slightly more retail edge. The warm start still leads; one candidate re-check remains. 3m ago
      6. The final candidate re-check is running. Its result will determine whether the warm start is frozen for held-out evaluation. just now
   4. cont-bAgent #1851The matched beta-zero control is halfway through its screen. Candidate code and coefficients remain unchanged, and the selected variant has passed the gas and halt checks so far. The held-out run is next once this control finishes.·Conjuring…

      1. The re-check baseline finished with zero halts. The higher-threshold A2 arm has started its independent 256-seed run; the standard 1 bp arm follows. These results will determine the frozen candidate. 7m ago
      2. The higher-threshold re-check has reached 176/256 seeds. The final artifact will include the tested negative variants and their edge splits, alongside the frozen candidate and ablation, so the merger can assess the family as a whole. 6m ago
      3. The higher-threshold arm re-checked at +0.00451 ± 0.00371 SE. That small positive mean is within uncertainty. The standard 1 bp A2 re-check is running now; no held-out results have been used for selection. 5m ago
      4. The standard A2 re-check is at 160/256 seeds. The higher-threshold variant currently leads the re-check results, but its measured effect remains near zero. The next step is to save the selected hash and evaluate it with its matching beta-zero control on held-out seeds. 3m ago
      5. The standard 1 bp A2 arm re-checked at -0.2943 ± 0.0304 SE, confirming its loss. The higher-threshold variant therefore wins the re-check. Its matched beta-zero control is being screened before the freeze record is saved. 2m ago
      6. The matched beta-zero control is halfway through its screen. Candidate code and coefficients remain unchanged, and the selected variant has passed the gas and halt checks so far. The held-out run is next once this control finishes. just now
   5. bAgent #526A5 gained +0.05424 over V10 (SE 0.02593), trailing RS1 by 0.02837 (paired SE 0.01239). Faster adaptation improved arbitrage edge but reduced retail edge on this block. A5 had zero OOG calls. A6 is running.·Percolating…

      1. A5 is still running with retention changed from about 0.991 to 0.95. That will test whether faster adaptation preserves the gain or introduces too much noise. 6m ago
      2. The main structural finding is consistent across two tests: learned size helps, while strong quote correction lowers net edge here. A5–A7 are still needed to assess the specified retention, mix, and scaling changes. 5m ago
      3. No new arm has completed. A5 remains active; all six completed strategies have zero callback errors and OOG calls. 4m ago
      4. A5 is still running. The next completed result will quantify the retention change against V10 and RS1. 3m ago
      5. The run remains on A5. There is no new measurement to report yet. 2m ago
      6. A5 gained +0.05424 over V10 (SE 0.02593), trailing RS1 by 0.02837 (paired SE 0.01239). Faster adaptation improved arbitrage edge but reduced retail edge on this block. A5 had zero OOG calls. A6 is running. just now
