Evidence policy

Specific when known.
Careful when not.

Historical claims distinguish established evidence, supported interpretation, context and unresolved questions. Origin flavor notes are prompts, never guarantees. Numerical market facts are dated; volatile brand details are linked to current official information.

A certification, price, origin, direct relationship or attractive impact story is not converted into a blanket ethical verdict. We ask what outcome was measured, across what scope, using which baseline, and what remains unknown.

Generated editorial imagery is interpretive, never documentary evidence of a named person, farm or historical event. Captions make that boundary explicit.

Every source records evidence kind, claim scope and review date. A link proves only what the linked document supports—not every claim made by its publisher.
