Status: internal pre-standard contract
Prepared: July 28, 2026
Linked Art issue: #637
Meta Museum distinguishes a scored reconciliation candidate from a
curator-confirmed assertion that two entities are not equivalent. An automated
`no-link` result is not promoted to a confirmed negative.
The internal `ConfirmedNegativeReconciliation` contract requires:
- a stable decision identifier;
- distinct subject and candidate identifiers;
- curator identity and an ISO timestamp;
- a non-empty rationale;
- at least one cited evidence source with a summary; and
- the score at decision time when one is available.
The contract is append-only decision evidence for review and audit workflows.
Its discriminated `confirmed-not-equivalent` state remains structurally
separate from the unresolved `candidate` state.
Linked Art boundary
The record carries `linkedArtProjection: "withheld-pending-standard"`. It does
not emit `distinct_from`, `notEquivalent`, `equivalent`, or another local
negative relationship. A projection may be added only after the Linked Art
community settles the property name and assertion pattern.
