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 training visit produced no instrument readings because the exercise concerned route documentation. The journal explicitly recorded that purpose. Empty numerical columns were therefore described as not collected, rather than as measured zeros.
The survey footpath ended at a locked training enclosure. A sketch showed the limit of the observer's view from the gate. The journal distinguished a route that could not be inspected from a route known to be absent.
