C20 · Reference edition 2026.11
Temporal notes — Review and interpretation
An impression can change during an observation. Record onset, development and persistence as separate descriptions where useful.
Scope and purpose
Review the record before drawing a conclusion. Look for missing context, ambiguous labels and claims that exceed the evidence. The purpose is to identify what can be understood from the record and what still requires a separate assessment.
Working notes
This atlas connects descriptive vocabulary, observation context and reference-sheet design. All example records are synthetic and exist to explain a method of documentation; they do not represent tested batches, product ratings or scientific results. The diagrams are original editorial graphics. Descriptions of perceived character are kept separate from ingredient, origin, health and certification claims. Read definitions and scale anchors before comparing records.
Practical example
Use a three-stage timeline rather than a single unexplained duration value.

Review checklist
Read the record without relying on memory; check every label; identify uncertainty; decide whether a specialist review is required; retain the original observation.
