C28 · Reference edition 2026.11
Sample identity — Comparison and alternatives
Blind labels and preparation records serve different purposes. Keep the label used during observation distinct from the preparation identifier.
Scope and purpose
Compare alternatives using the same question and context. A difference in wording, layout or scale is not automatically a difference in performance. Keep the original observations available and explain which differences are meaningful for this comparison.
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 synthetic codes such as C-01 and C-02 in an illustrative comparison sheet.

| Scope and purpose | Blind labels and preparation records serve different purposes. Keep the label used during observation distinct from the preparation identifier. |
| Limits and interpretation | Example records are invented for explanation, not evidence from tested batches. |
Review checklist
State the comparison question; align context and labels; list common features separately from differences; leave unsupported conclusions open.
