Reading note
Keep a claim attached to the material and setting that its report describes. Check whether the subject is an ingredient or a finished formula, how it was applied, and what circumstances surrounded the observation. If a story extends that finding to a different formulation or route, locate the evidence offered for the extension. A shared ingredient name should prompt an identity check, not close it. Record any mismatch explicitly so a reader can see where the original observation ends and a separate claim would need its own supporting comparison.
