Some POSS-I multiple-transient events are reported to form linear alignments consistent with point sources along a shared sky-projected path.

Multiple-transient events forming apparent linear alignments have been published in peer-reviewed literature (PASP) and extended in subsequent preprints reporting alignments of five to eight sources on seven plates exceeding uncorrected Monte Carlo thresholds. This documents the presence of geometric alignments in the catalog. The strongest opposing consideration is that Watters et al. demonstrated that approximately one-third of the linear-cluster sources could not be reliably distinguished from ordinary catalog stars, and un-preregistered alignment searches suffer heavily from look-elsewhere effects.

As stated, the claim is that alignments are reported, and they are: TRN-E018 documents seven plates with 5–8-source alignments at p < 0.03, and the peer-reviewed PASP 2025 paper exists. But Watters found a third of the linear-cluster features were not confidently distinguished from catalog stars (TRN-E011), the alignment criteria are post hoc with unpreregistered trials accounting, and the primary PASP paper was never read in full for this ledger. Strongest opposing consideration: the star-contamination finding in TRN-E011, which attacks the substrate directly.

TRN-E018 reports seven plates with alignments of five to eight high-scoring candidates beyond the paper's Monte Carlo expectations. However, the criteria were not preregistered, the reported probabilities are modest in a many-plate alignment search, and the candidate marks inherit the disputed catalog provenance. The strongest opposing consideration is TRN-E011's finding that a substantial fraction of linear-cluster features were not confidently distinguishable from catalog stars, so the physical alignment interpretation remains unsettled.

Alignments of multiple transients are reported in VASCO-team papers and extended by Doherty’s ML-scored seven-plate search with modest Monte-Carlo p-values. Watters finds a substantial fraction of reported linear-cluster features not cleanly separated from catalog stars. Look-elsewhere effects and post-hoc alignment criteria are uncontrolled. Strongest opposing consideration: chance projections and residual stellar contamination readily produce apparent alignments in large unvalidated candidate lists.

As worded the claim is about what has been reported, and that much is solid: a peer-reviewed PASP paper and a second preprint reporting alignments of five to eight sources on seven plates exceeding Monte Carlo expectations (TRN-E018). Read substantively the picture is much weaker, and I flag that the verdict does not endorse the substance: TRN-E011 reports that a third of the reported linear-cluster features were not confidently distinguished from catalog stars, and TRN-E018's own record notes that alignment searches over many plates with a post-hoc criterion and no preregistered trials factor are the classic setting for look-elsewhere inflation. Any inference from alignments also inherits the catalog's contested provenance.

TRN-E018 (weak, qualifies): seven plates carrying alignments of five to eight ML-scored sources exceeding Monte Carlo expectation (p<0.03), sources point-like rather than trailed. The alignment criterion is post hoc, trials are not preregistered, the author is now group-affiliated, and alignments among marks inherit the provenance question. SRC-VILLARROEL-2025-PASP, the founding alignments paper, is characterized only through others.

Held on its anchor; the source paper was not read in full for the ledger and no evidence record is admitted on it. TRN-E018 (weak, qualifies; admitted on TRN-C003 and TRN-C022) reports alignments on seven plates with a post-hoc criterion and modest p-values, inheriting the catalog's provenance.

Multiple preprints report statistically improbable linear alignments of five to eight transients on several POSS-I plates. However, critical reviews indicate that a significant fraction of these candidate features cannot be reliably distinguished from known catalog stars, and the alignments suffer from uncorrected trials factors across multiple plates. Strongest opposing consideration: The low Monte Carlo p-values (p < 0.03) reported on several plates where candidate points exhibit star-like morphology rather than continuous trailing.

Alignment claims exist in a peer-reviewed PASP paper, but that paper was not read in full for this ledger (the source record says so), and the closest available record (TRN-E018) is a same-network preprint with modest p-values, no preregistered alignment criterion, and no trials-factor accounting. TRN-E011 reports that a third of the reported linear-cluster features were not confidently distinguished from catalog stars. Strongest opposing consideration: alignment searches over many plates with post-hoc criteria are the classic setting for look-elsewhere inflation, on a catalog whose candidate status is contested.

TRN-E018 reports seven POSS-I plates containing alignments of five to eight point-like candidates exceeding the study's Monte Carlo expectations. That is direct support for the limited statement that some events are reported to form linear alignments. The strongest opposing consideration is the unpreregistered alignment criterion and associated look-elsewhere risk, compounded by the unresolved provenance of the underlying marks.

Alignments are asserted in the PASP paper (unread in full) and extended by a later ML-scored search reporting seven plates with 5–8 sources above Monte-Carlo expectations (E018), yet p-values are modest, criteria post-hoc, and the underlying candidates inherit the contested catalog provenance. Strongest opposing consideration is look-elsewhere inflation and lack of preregistered alignment definitions or independent-catalog replication.

As stated, the claim is only that such alignments are reported, and they are. E018 reports seven plates with point-like alignments of five to eight sources beyond Monte Carlo expectation, and Watters analyzes the reported linear clusters (E011). This verdict records the reporting, not the alignments' reality. Strongest opposing consideration: the substance is weak. A third of the linear-cluster features were not distinguished from catalog stars (E011), and E018's p<0.03 uses a criterion that was not preregistered and was searched across many plates.

Held on its anchor alone. The source paper has not been read in full, and the characterisation comes from its title and a critic's discussion. A second, related alignment preprint (weak, qualifying) is filed against other claims and is not counted here. No admitted record carries this proposition.
