If the VASCO transients are specular sunlight reflections from planar facets at 20,000–35,786 km altitude with flash durations of 0.1–1 s and reflectivity 0.1–1, the reflecting facets have equivalent linear sizes from centimetre scales up to approximately 3 m.

Modelling preprint: inferred reflecting-facet sizes from centimetres to ~3 m — part 2

what the source states: The size calculation adopts altitudes of 20,000 km to 35,786 km, specular reflection, flash durations of 0.1–1 s, reflectivity r = 0.1–1, and dilution over the plate exposure, since "these flashes are diluted over the exposure time" of approximately 50 minutes for POSS-I red plates.
what we infer: Every input is assumed (altitude, specularity, duration, reflectivity); the output is a derivation, not a measurement. It bears on TRN-C021/C022 only conditionally and adds no evidential weight to whether the marks are flashes at all.
limitations: Entirely model-dependent on unmeasured inputs
Planar perfect-reflector idealisation
Sample excludes R ≤ 12.4 mag sources, biasing toward small facets
Direction set to "context" (from "supports") by the second reader (claude-sonnet-5, 2026-09-10, run 2026-09-10-verify-transients-174405, verify-v5) at intake: The passage at p.13 (and Figures 3–4) accurately describes the method's input assumptions (altitude range, specular reflection, flash duration, reflectivity, exposure dilution) and the quoted phrase is correctly attributed and located. However, the record only restates the modelling premises rather than the derived outcome (the cm-to-3m facet sizes) that the conditional claim TRN-C111 actually asserts, so it functions as background/method context for the inference rather than as direct support for the claim's stated size conclusion; I judge the appropriate direction to be 'context' rather than 'supports'.

Modelling preprint: inferred reflecting-facet sizes from centimetres to ~3 m — part 3

what the source states: Across the adopted parameter range, the modelling yields reflecting facets with "equivalent linear sizes ranging from centimetre scales" up to approximately 3 m, depending on observed magnitude, flash duration, and specular reflectivity.
what we infer: Every input is assumed (altitude, specularity, duration, reflectivity); the output is a derivation, not a measurement. It bears on TRN-C021/C022 only conditionally and adds no evidential weight to whether the marks are flashes at all.
limitations: Entirely model-dependent on unmeasured inputs
Planar perfect-reflector idealisation
Sample excludes R ≤ 12.4 mag sources, biasing toward small facets

Modelling preprint: bright-source exclusion in the catalog biases inferred sizes downward — part 1

what the source states: An important limitation of the study is that it relies on the sample selection of Solano et al. 2022, "in which bright objects were excluded".
what we infer: The authors' own caveat: the size range is a floor set by selection, not a property of any population.
limitations: Authors' self-stated limitation; magnitude of the bias not quantified

Modelling preprint: bright-source exclusion in the catalog biases inferred sizes downward — part 2

what the source states: As a result of the bright-object exclusion, "larger objects in geosynchronous orbits were filtered out", biasing the sample toward smaller objects and potentially affecting the conclusions.
what we infer: The authors' own caveat: the size range is a floor set by selection, not a property of any population.
limitations: Authors' self-stated limitation; magnitude of the bias not quantified

an honest empty state

This claim is in the ledger but not in the current edition's featured set. Nothing here has been assessed — that absence is information, not an oversight.

Still missing: plain-language gloss, credibility assessment, diagnosticity assessment, strongest objection, what would change our mind. A claim gains them when an edition features it and the edition's adopted assessment supplies the full treatment — a decision the panel reviews, not a field anyone flips.
