Jow & Scott 2020: marginalize over ring size and the 99.98% becomes 87%

what the source states: "We investigate recent claims for a detection of 'Hawking points'... at the 99.98% confidence level. We find that, after marginalization over the size of the rings, an excess is detected in Planck satellite maps at only an 87% confidence level (i.e., little more than 1σ). Therefore, we conclude that there is no statistically significant evidence for the presence of Hawking points in the CMB."
what we infer: A textbook look-elsewhere correction: the proponents searched a family of ring sizes but quoted significance for the best one. This is the cleanest single demonstration in the case that the headline numbers live in the analysis choices — the data are unchanged; only the accounting for the search is.
limitations: Does not address the Planck–WMAP co-location argument.
An 87% excess is a residue, not a zero; the record honestly leaves ~1σ on the table.

Jow & Scott 2020 §2: instrumental noise does not contribute significantly to the Hawking-point signal

what the source states: The source states that 'adding the Planck half-difference maps as an estimate of the noise to the simulations did not alter the estimated probability distributions', so the authors 'conclude that instrumental noise does not contribute significantly to the HP signal at the scales we are considering'.
what we infer: Bears on the cross-map (WMAP/Planck) co-location argument that the article leaves standing: if noise is negligible at Hawking-point scales, any strong feature of the CMB signal must appear in both instruments under every hypothesis, ΛCDM included, so co-location establishes the spots are on the sky and nothing further. I rate this weak toward CCC-C004 because it does not touch the significance number itself.
limitations: Jow & Scott do not themselves discuss the WMAP co-location; the inference about it is mine.
Direction set to "context" (from "qualifies") by the second reader (claude-sonnet-5, 2026-09-10, run 2026-09-10-verify-ccc-192550, verify-v5) at intake: The quoted passage only rules out instrumental noise as a confound in estimating the probability distribution of gradient values; it does not bear on whether the 99.98% confidence detection of Hawking points holds up, which is what CCC-C004 asserts. It neither supports nor limits the specific confidence-level claim, so it functions as background methodological context rather than a qualification of the claim's content.

Jow & Scott 2020 §3.1: no anomalous clustering of the most significant Hawking points — part 1

what the source states: An et al. claim that clustering of Hawking points on the sky could be further evidence for CCC, since one might expect the distribution of supermassive black holes in the previous aeon to be highly clustered: "clustering of these features could be further evidence of CCC".
what we infer: This is the Hawking-point analogue of the ring-centre anisotropy argument (CCC-C504) and is the only independent test of a proponent clustering claim on the record; I keep it on its own claim rather than folding it into CCC-C504, which concerns a different feature population.
limitations: Only 100 simulations for the clustering statistic; only the top 30 points at two scales.
Direction set to "context" (from "supports") by the second reader (claude-sonnet-5, 2026-09-10, run 2026-09-10-verify-ccc-192550, verify-v5) at intake: The quoted passage merely restates An et al.'s motivating claim that clustering would support CCC; it is background framing for the section, not Jow & Scott's actual clustering finding (no anomalous clustering) that CCC-C509 asserts. As such it does not itself support or undermine CCC-C509's specific quantitative finding, but simply provides context for why the analysis was performed.

Jow & Scott 2020 §3.1: no anomalous clustering of the most significant Hawking points — part 4

what the source states: From 100 Gaussian simulations drawn from the Planck best-fit power spectrum, the distribution of the mean nearest-neighbour distance at both scales is roughly Gaussian "with mean 0 . 20 and σ = 0 . 03".
what we infer: This is the Hawking-point analogue of the ring-centre anisotropy argument (CCC-C504) and is the only independent test of a proponent clustering claim on the record; I keep it on its own claim rather than folding it into CCC-C504, which concerns a different feature population.

Jow & Scott 2020 §3.1: no anomalous clustering of the most significant Hawking points — part 5

what the source states: For both scales the data value lies within 1σ of the Gaussian expectation, so there is no evidence that HPs exhibit anomalous clustering: "we do not find any evidence that HPs exhibit" clustering beyond that of a Gaussian sky.
what we infer: This is the Hawking-point analogue of the ring-centre anisotropy argument (CCC-C504) and is the only independent test of a proponent clustering claim on the record; I keep it on its own claim rather than folding it into CCC-C504, which concerns a different feature population.

Jow & Scott 2020 §3.2: no persistent E-mode polarization structure at Hawking-point locations — part 1

what the source states: Stacking the Planck 2018 SMICA temperature and E-mode maps was performed around all HPs in the temperature map with |â| > 2, i.e., "a 2 σ significance threshold, for the scales" (r1, Δ) = (0.01, 0.02) and (0.01, 0.03).
what we infer: Negative evidence of low diagnosticity, recorded under the negative-evidence policy: the source itself notes that 'Without a precise prediction for the polarization profiles of HPs, it is not possible to search for specific features', so CCC is not tested by this null. Its value is that any future CCC polarization prediction now has a stated null to meet.
limitations: CCC makes no polarization prediction; the null constrains nothing in the theory as currently stated.
Visual assessment of stacks; no quantitative limit given.

As written, this record's statement is procedural background rather than evidence supporting the no-signal claim, so it should be marked as context rather than supports.

what the source states: In addition to no statistically significant HP signal in the CMB temperature, there is "no evidence for a corresponding signal in polarization".

Jow & Scott 2020 §3: a third of the Hawking-point excess at the claimed scales comes from the single most significant point — part 1

what the source states: Recomputing A⁻ at the scales (0.01, 0.02) and (0.01, 0.03) while omitting the single point with the highest |â| gives A⁻(0.01,0.02) = 5.50 and A⁻(0.01,0.03) = 4.13, so "about a third of the signal at these scales comes from the single most significant points".
what we infer: Independently of the look-elsewhere correction, the reported excess is dominated by two individual features; this is a distinct fragility from the 99.98%→87% marginalization already recorded in CCC-E010 and is consistent with the few-feature dependence Bodnia et al. later diagnosed (CCC-E012).
limitations: Computed on Planck 2018 SMICA, whereas An et al. used 2015 data; Jow & Scott note minor location/rank differences between the analyses.

Jow & Scott 2020 §4: the CCC prediction has been revised three times; only an a-priori precise prediction could have escaped the marginalization — part 5

what the source states: Alternatively, the conclusion could only have been avoided if "the predictions of CCC could have been made much more precise" before looking at the data.
what we infer: A critic's account of the shifting signal model, consistent with the study table (CCC-E023); it is the proponents' opponents describing them, so it is credible on the sequence of published claims and not independent on the moral.
limitations: Adversarial source on the interpretive point.
