Non-medical structural fixture

Every displayed fact needs a trail.

Provenance explains which source supplied a fact, what role that source played, when the fact was observed and checked, and whether editorial review changed its status.

Fixture source record

Identity and use stay separate.

A source can be identifiable and available while still serving only as context, disclosure, contradiction, or a discovery lead.

Independent fields

Four questions, not one badge.

Identity

Which record is this?

Canonical IDs and aliases help deduplicate records. They do not prove that a statement is accurate.

Role

Why is the source present?

Primary support, context, contradiction, disclosure, and discovery lead are distinct uses.

Verification

When was it checked?

Observed and last-verified dates reveal staleness without implying continuous monitoring.

Confidence

How certain is the stored fact?

Confidence in transcription is not evidence maturity, efficacy, safety, or editorial approval.

Editorial status

Can it be displayed?

Fixture, reviewed, corrected, superseded, retracted, unavailable, and unknown remain explicit.

Validity

When was it true?

Valid-from and valid-to dates preserve changing real-world status without erasing earlier values.

Honest states

Missing context is not a negative result.

Unknown

Not established

The fixture source does not establish the field; it must not become false or zero.

Unavailable

Cannot be checked

The last verified date and limitation remain visible.

Invalid

Cannot be projected

A broken source reference or validity window blocks the record instead of being guessed.
