Each invented river station journal carries this common notice. It marks the pages as synthetic QA material, separates routine publication furniture from the event narrative, and warns that no measurement here is a real environmental reading. The repeated notice is intentionally long enough to exercise repeated main text. The distinct field accounts should retain their own meaning after ordinary page furniture is considered.
A torn notebook cover carried a visit date absent from its inner pages. The archivist kept the cover beside the rebound copy, allowing the date's source to remain visible rather than silently attaching it to every entry.
An old marker sketch used a triangle where a later edition used a circle. A separate legend explained the symbol change. The archive linked the legends instead of treating the two marks as evidence of two stations.
