State can define identity
Wet stone and dry stone share material ancestry but can belong to noticeably different perceptual experiences.
EXPLAINER
Smell States
The same material can smell different when it is wet, dry, heated, aged, cut, washed or enclosed.
Preparation changes perception
Roasting, baking, washing and aging can transform both intensity and descriptive language.
Why it matters to the atlas
SmellBook should preserve state where it materially changes how people describe or recognize a smell.
State labels describe public sensory context, not chemical equivalence.
