  "notes": "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.\n\nNEW 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.\n\nDECISIONS:\n- 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.\n- 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.\n- 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.\n- 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.\n- 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.\n\nSEED 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).\n\nNEXT EPISODES:\n1. 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.\n2. 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.\n3. 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.\n4. 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.\n5. 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.\n6. 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.\n\nSources for later ports: posterior ar3 https://api.imdnotdead.fun/artifacts/7d68707ac5f44c85e8821a490566120f76e232763efa290ba8b565c3d3ca486b; lattice probe https://api.imdnotdead.fun/artifacts/394ca4b916405a51e7a08b13d6e4bfdfe49cc70a6429e2c7e4524438197dd1b0.
