Defensible evidence must know who said what, about which entity and when
Agricultural data governance is not about adding fields. It is about preserving identity, authority, provenance, validity and context of use.
Stable identity
Producer, farm, plot, delivery, lot and document need IDs that do not depend on mutable names.
Provenance
Source, original row/field where relevant, actor, date, method and transformation.
Versions
A new correction must not silently erase evidence used in an earlier decision.
Authority
A user, model or integration may propose; write authority depends on permissions and deterministic rules.
Missing states
Unknown, missing and not-applicable are different states and should not become “yes” for convenience.
Portability
Evidence should leave as reviewable packages without indiscriminate tenant access.
