user: Role fix first. jimmy = Recorder / coordinator only. planner = Proposer. reviewer = Critic. builder = Executor. jimmy does not write the spec and does not propose the claim. That removes the self-authorship problem on the same claim. planner writes the spec; reviewer kills or passes it independently; jimmy only records the finished autopsy and advances the queue. Claim confirmation The KXBTCD lag-vs-spot claim is acceptable as the first concrete claim. It matches the relative-value (taker) primary, has a closed-form fee, an existing harness, and clear kill criteria. The original seeded basket claim can sit in the queue behind it or be treated as a later variant. Use this one now. The measurement-artifact flag is material: if the order-book read is as stale as the Kalshi update, the measured edge is your own latency. That belongs in the pre-registered kill criteria (or as an explicit measurement the Executor must log). reviewer should treat an unmeasured book-vs-spot timestamp delta as a reason to kill or park until it is instrumented. Go-ahead • planner produces specs/KXBTCD-lag-vs-spot.spec.yaml from the spec you wrote. • reviewer performs the independent kill/pass on that spec only. • No file writes or commits until you explicitly approve the spec + reviewer decision. • jimmy records only after that approval. That keeps the engines separate and the loop disciplined. Paste the spec + reviewer output here when ready and I will do the higher-reasoning pass on the pair.

assistant: Loop ran. Planner → spec; Reviewer → independent verdict. Nothing committed — both artifacts sit in scratch, no repo file created, per your no-writes-until-approval rule.

Produced by planner (profile), spec id KXBTCD-lag-vs-spot:

Claim: In Kalshi KXBTCD hourly above/below markets, final 2–50 min before strike close, a YES/NO taker with post-fee model edge ≥ 0.04 has positive mean realized PnL/contract after fees, over ≥300 settled markets sampled walk-forward.

Pre-registered kill criteria:

• K1 mean post-fee PnL/contract ≤ 0 → killed
• K2 model Brier ≥ market-mid Brier → killed
• K3 cost-stress (fee×1.5, +1 tick, jointly) flips edge negative → killed
• K4 <300 settled post-registration markets → inconclusive, not kept
• K5 edge confined to one sigma-tercile → parked, not kept
• Falsifying assumption: spot is fresh and the book lags; unmeasured book-vs-spot timestamp delta → KILL/PARK (measurement artifact).
• Closed enums for outcome + cause-of-death; BDD acceptance criteria for pass/kill/inconclusive.

Produced by reviewer (independent profile), VERDICT: KILL-OR-PARK

Required changes (its words, condensed):

1. Outcome enum not closed — "parked" is used as a first-class outcome (K5, falsifying assumption, kill scenario) but has no enum member. Add it or remap every "parked" explicitly.
2. No statistical decisiveness floor on K1 — near-even $1 binaries at N=300 give SE(mean)≈0.029, so a true 0.04 edge is t≈1.3; a luck

20261011-000205 session 20261010_154339_ceb19ec0

user: Higher-reasoning pass: the reviewer’s KILL-OR-PARK is correct. Do not keep the claim as written. The load-bearing objections are #2 and #4. They attack whether a pass would mean anything. • Statistical decisiveness (#2). At N=300 on near-even $1 binaries the standard error of the mean is roughly 0.029. A true 0.04 edge is only about t=1.3. A lucky positive sample can clear “mean > 0” without the edge being real. Requiring a one-sided confidence interval lower bound > 0 (or a pre-specified minimum margin plus a power calculation that shows N is adequate) is the minimum fix. Without it the test cannot distinguish edge from noise, so a pass is not evidence. • Window purity (#4). Any evaluation that can include pre-registration entries contaminates the out-of-sample count. Every kill-capable metric must be computed strictly on markets entered after the pre-registration timestamp. The “whichever comes first” language has to go. The other points are real but secondary: • #1 (closed outcome enum) and #5 (instrumented slippage vs flat tick, pre-specified per-tercile test) are spec bugs. Fix them so the record is unambiguous. • #3 (gate the measured latency) is the measurement-artifact risk made operational. A max tolerated book-vs-spot delta, how server time is established, and “large measured delta = measurement_artifact” should be in the spec. Until that is instrumented the falsifying assumption remains live. Independence note. Separate profiles satisfy the process rule we set. The

assistant: Path 1 — and one correction to Path 2 that matters more than the choice.

The claim is untested, not dead. #2 and #4 are defects in the draft spec; nothing has been run against the KXBTCD edge. Path 2 as written files an autopsy with cause = "statistical decisiveness + OOS window contamination." But that's a documentation defect, not a cause of death from evidence. Filing it would write a false death into the corpus — a claim recorded as dead that was never tested. That's the survivorship-bias back door this whole project exists to close. A corpus that lies about why something died is worse than no corpus.

So:

• Path 1 (my pick): planner closes #2 (CI lower bound or powered N + power calc) and #4 (strict post-registration window only), plus the spec bugs #1/#3/#5; reviewer re-reviews the revised spec only. Clean, and it actually exercises the harness under a valid test.
• Path 2, corrected: if you'd rather drop this claim and move on, do it as a withdrawal (status: never-tested), not an autopsy. Same speed, honest record. The claim isn't dead — it was never run.

Either way, no death gets recorded for a claim that was never executed. The only version I'd refuse is "file it as a death."

Say 1 and I'll dispatch planner for the revision now, then reviewer on the revised spec. Say 2 and I'll have the recorder file a withdrawal (still no repo write until you approve the wording).

user: Correction accepted. The claim is untested. #2 and #4 are defects in the draft spec, not evidence of death. Filing an autopsy that records a cause of death for a claim that was never executed would put a false death in the corpus. That is worse than no record. Path 2, if used, is a withdrawal (status: never-tested), not an autopsy. Path 1 confirmed. planner revises the spec to close: • #2 — one-sided CI lower bound > 0, or powered N plus an explicit power calculation • #4 — every kill-capable evaluation restricted to the strictly post-registration OOS window • plus the spec bugs #1, #3, and #5 reviewer re-reviews only the revised spec. No repo writes and no autopsy until you approve the revised spec + reviewer verdict. Dispatch planner for the revision. Bring the revised spec and the reviewer’s second verdict here for the higher-reasoning pass.

assistant: Round 2 done. Both artifacts below; still uncommitted.

Spec v1.1.0 (planner) — all five prior changes materially addressed:

• #2 → power_analysis block, required_N = 967 (N = (1.645+0.842)²·0.25/0.04²). K1 now requires one-sided 95% lower bound > 0, and states bare "mean > 0 is NOT sufficient."
• #4 → "whichever comes first" removed; every kill-capable metric (K1/K2/K3/K5) bounded strictly to entries after the registration timestamp; K1 stops exactly at N=967 (fixed-N OOS).
• #1 → outcome_enum now {kept, killed, parked, inconclusive} + parked_semantics.
• #3 → latency_gating: max book-vs-spot delta 1000 ms, spot-freshness 500 ms, max NTP skew 250 ms, per-venue server time cross-checked vs local NTP; measured-but-exceeding delta → measurement_artifact (KILL).
• #5 → slippage now instrumented (per-fill realized fill-vs-mid, no flat tick), K3 stresses at 1.5×; K5 gets a Bonferroni-adjusted (α/3, z≈2.128) per-tercile test with an explicit borderline rule.

Reviewer second verdict: KILL-OR-PARK — all five CLOSED, one new defect.

• New issue #1: K1 carries an undefined discretionary kill clause — "OR realized point estimate inconsistent with assumed_effect_size 0.04" — no numeric bound, no tolerance. It reintroduces researcher discretion into the one gate that must be automatic, and it's redundant with the LB>0 test. Fix: define it numerically or delete it.
• Minor (non-fatal): at ~322 markets/tercile with z

20261011-005120 session 20261010_154339_ceb19ec0

user: Higher-reasoning pass: delete the discretionary clause, then the spec is a valid test. The new issue is real and load-bearing for process integrity. The clause “OR realized point estimate inconsistent with assumed_effect_size 0.04” has no numeric bound. It reintroduces researcher discretion into the one gate that must be automatic, and it is redundant with the one-sided lower-bound > 0 requirement. Delete it. Do not replace it with a new tolerance. The minor note on K5 is correctly flagged. At ~322 markets per tercile with the Bonferroni adjustment, edge_present(tercile) will almost never fire for a true 0.04 edge. Parking on regime dependence is near-inert. That is acceptable provided the borderline rule routes those cases to K1/K2 and the record does not treat “parked” as a live expected outcome. The residual risk (paper walk-the-book fills ≠ live-realizable fills; two correlated stale sources can both lag inside the 1000/500 ms gates) remains the weakest link. It does not invalidate the spec as a paper test. It does mean a later keep decision, if one ever occurs, still requires a live-fill measurement before any capital discussion. Decision Micro-revise: planner strikes the discretionary clause from K1. Reviewer re-reviews only that change. A PASS on the revised spec means only that the test is valid and pre-registered. It does not mean the KXBTCD edge exists. The harness run decides that. No repo write until the revised spec and the reviewer’s third verdict are both here

assistant: Round 3 — PASS. Final pair below; still nothing written or committed.

Spec v1.1.1 (planner) — diff vs v1.1.0 is exactly two lines: version: 1.1.1, and K1's threshold now reads only "one-sided 95% lower bound <= 0 (cannot establish positive edge above noise)". Verified: zero occurrences of the discretionary clause, no replacement tolerance added, power_analysis.assumed_effect_size: 0.04 correctly retained.

Reviewer third verdict: PASS

• CLAUSE_REMOVED: yes. DANGLING_REFS: none. OTHER_REGRESSIONS: none.
• All five v1.1.0 closures intact (required_N=967 + power calc; LB>0; strict post-registration OOS; closed enum + parked_semantics; latency gating with measured-but-exceeding → measurement_artifact; instrumented realized slippage; Bonferroni per-tercile K5). "K1's gate is now purely automatic."
• Residual risk (its words): K1 now rests entirely on the one-sided LB at exactly N=967, where the spec's own derivation puts expected LB ≈ 0.0135 — knife-edge above zero. It presumes σ²≈0.25; if realized per-market variance runs higher (volatile regimes), N=967 under-powers K1 and a genuine edge can fail on the variance model — a false KILL or a near-tie a viable edge can't clear.

Two coordinator notes before you approve:

1. The knife-edge must be measured, not assumed. The 0.0135 margin rides on σ²=0.25. The run has to log realized per-market variance from the start, so if it exceeds the basis we revise N pre-registered, before the clo
