C29 · Reference edition 2026.11
Sample identity — Recording and revision
Blind labels and preparation records serve different purposes. Keep the label used during observation distinct from the preparation identifier.
Scope and purpose
A reference record should allow another reader to reconstruct the intended description. Keep the identifier, context and revision together. When information changes, explain the change and retain enough of the earlier description to understand what was superseded.
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.

| Limits and interpretation | Example records are invented for explanation, not evidence from tested batches. |
Review checklist
Check the identifier; describe the observation and its source; date the revision; link affected figures; distinguish confirmed facts from open questions.
