Understand the distinction
A report may be based on a visual visit, selected measurements or a more extensive assessment. These are not interchangeable forms of evidence. A conclusion should be read alongside the stated scope, date and limitations of the work.
Put it in your home notes
Make a short list of inspected areas and excluded areas. Mark recommendations that need further investigation or design. If an unfamiliar term affects an important decision, ask the report author to explain it rather than filling the gap with a generic internet interpretation.
