Two GBIF records for a plant in Cyprus point back to the same person's observation. Their separate database numbers therefore add no second sighting. This was one of the concrete results from following three discovery leads through their sources: possible national species records, early Korean technology terms and proposed protein classifications.
For each lead, I kept the candidate claim beside the record that could support it. The comparisons recovered useful source links and corrected counting and reference errors, while leaving the stronger discovery claims unresolved. Here are the records a reader can check, and the evidence each comparison actually supplies.
Two plant records, one observation
GBIF collects biodiversity records from different datasets. A record number identifies a database entry; it does not guarantee an independent observation. GBIF 6133546711 and GBIF 6541216313 both reference iNaturalist observation 334616445, recorded by Marios Thoma on 19 October 2024 and identified there as Oxybasis chenopodioides.
One entry comes through the iNaturalist dataset and the other through Alexander Sukhorukov's taxonomic dataset. The coordinates have different decimal precision, so I used the explicit source link and observation day to reconcile them. These are two representations of one observation. The taxonomic dataset's official version 1.0 metadata already lists a related Taxonomy manuscript as submitted; that description does not verify its acceptance or publication.
A second source pairing changed the location and year. GBIF 6251470106 references Елена А. Кизилова's Astana observation 351186237, dated 19 April 2026. It is separate from Dzhus Maxim's Almaty observation 241801642, dated 13 September 2024. Both are labelled Cardamine occulta. Treating the GBIF entry as evidence for the earlier Almaty observation would attach one observation's metadata to another.
Across the four country-and-species candidates, the source mapping contains five underlying observations and five linked GBIF entries. That equality hides the duplicate Cyprus representation and the Almaty observation for which this comparison has no verified GBIF match. The other two observations were Aeshna grandis labelled Spain, recorded by Olaf Hakelberg, and Selysiothemis nigra labelled Austria, recorded by twity11_gabrielarossi. The preserved Spain comments question whether the location was France or Spain; the Austria record is a single adult with positional accuracy of 1,754 metres.
None of the four national-first claims is confirmed here. They require diagnostic and locality evidence alongside exact historical and national records. In particular, the Cardamine occulta entry and country legend in the 2021 Tian-Shan checklist remain unread. A single adult observation also cannot establish local breeding or a climatic cause.
The observations belong to their credited observers. The iNaturalist collection carries CC BY-NC terms, while the Sukhorukov dataset declares CC BY 4.0; individual records and photographs have their own licence fields. This article cites the identifiers and factual source links without redistributing photographs or complete source records. The three GBIF identity links were refreshed for this check; iNaturalist credit, dates and licence fields come from the preserved official snapshots.
An early written form needs a dated witness
The Korean lead concerned five technology terms. Their Chinese-character forms occur in edited historical texts or earlier scholarly quotations. The dates below describe journeys or recorded events, rather than independently dated surviving manuscripts.
| Written form | Meaning in this comparison | Context year | Evidence inspected |
|---|---|---|---|
| 電信 | Telegraph | 1876 | Indexed edited text of 日東記游 |
| 電報 | Telegram | 1882 | Indexed edited entry in 使和記略 |
| 郵便 | Post | 1884 | Official Gojong Annals transcription |
| 鐵道 | Railway | 1881 | Passage quoted by Song Min in 1999, printed p.135 |
| 鐵路 | Railway | 1876 | Indexed edited text of 日東記游 |
The railway example exposes two separate dating questions. The edited travel account contains the written form 鐵路 in an account associated with Kim Gisu's 1876 journey. The official dictionary entry displays the Korean form 텰로 alongside 鐵路 in an example attributed to the 1880 Hanbul jajeon, p.515. A Classical Chinese sentence and a dictionary pairing Hangul with Hanja supply different evidence about Korean lexical use. The travel year alone establishes neither the date of the surviving witness nor the Korean pronunciation of the term.
The edited collection has its own history. The National Institute of Korean History's preface is dated November, Dangi 4291, corresponding to 1958. It credits Sungkyunkwan University for lending the originals of 日東記游 and 使和記略. That acknowledgment identifies a historical lender; it supplies no current shelfmark or date for the original manuscript. The 1958 dateline dates the preface. The edition's publication date has not been independently verified.
The postal passage is in the Gojong Annals, rather than the Seungjeongwon Ilgi source originally suggested. Its official page supplies the locator volume 21, leaf 14 verso, and National Institute facsimile volume 2, p.141. The transcription contains 郵便 outside the institution-name compound 郵便局. I recovered the locator but did not visually verify the original page image.
Song Min's 1988 article already discusses several of these delegation-record examples, and his 1999 article quotes the 1881 電信 and 鐵道 passage. Those authors and sources retain credit. The visible dictionary examples are also incomplete and not always chronological: the displayed 鐵路 examples run 1895, 1880 and 1898, with a control for more examples. A complete first-use claim would need the exact editions, all relevant dictionary examples and the corresponding prior scholarship, including entries by Lee Hanseop that have not yet been checked. This comparison establishes no new first Korean use or dictionary correction.
Checking the reference structure and earlier functional work
Proteins can share an overall shape while the evidence for a particular family relationship remains incomplete. For this lead, I checked both the reference used in the proposed comparison and whether an earlier study had already described a structural relationship.
DUF1688/PF07958 and AGOG/PF09171 label two protein families; the PF codes identify entries in the Pfam family database. The code 1XQP identifies a particular reference structure in the Protein Data Bank. DALI compares three-dimensional protein shapes. In Holm's DALI study, the author's example table already links those families through 1XQP and records a DALI Z score of 11.9. The structural connection has therefore been reported before. The table does not decide which reference best matches the particular models in the new candidate summary.
The candidate summary instead compared DUF1688 models with structure 7U91, another Protein Data Bank identifier. RCSB identifies that reference as Qng1/DUF2419 and cites Hung and colleagues' primary paper. DUF2419 and DUF1688 are different family labels. Their comparison may be worth examining, but neither the label nor structural similarity proves that the proteins perform the same reaction. The summary uses TM scores, another measure of how protein structures match after alignment. TM and DALI Z use different measures, so their numerical values cannot rank the two reference matches against one another.
The KIAA0825 lead raised another priority question. Kenta Kuramoto, Min Chen and Congcong He had already posted a functional preprint on 17 September 2026. A later first-functional-characterisation claim would overlook that work. Its status is a preprint, and the proposed CATCHR structural-family assignment remains a separate unresolved question; an earlier functional study does not by itself settle that assignment.
The original model identifiers, complete comparison tables, alignment coverage and matched controls are missing from the supplied package. I have therefore retained the comparative scores as attributed summary claims and performed no new alignment or functional measurement. Those inputs are needed to decide whether the proposed matches are family-specific, rather than general similarities between helical proteins. Neither a new function nor a confirmed family assignment is established by this audit.
The other three checks
These cases complete the source-audit accounts for three of six leads. The other three have separate public analyses: dated newspaper examples compared with dictionary dates, two published estimates from the same clinical trial and 37 earthquake records whose depths read 10 km. The trial and earthquake articles include their reproducibility packages. Each article distinguishes its documented comparison from the stronger claim that would require additional evidence.
