Audit authorized creation past a block

Context

The recorded blocking choice keeps existing suggestions visible and requires accountable exceptions.

Decision

Blocking applies to ordinary record creation; an authorized exception requires an explanation and is stored atomically with the new record, while matched pairs remain reviewable.

Alternatives Considered

Remove blocked matches from review. This would conceal records staff still need to assess.

Allow every creator to bypass blocking. The recorded choice requires separate authority and an audit reason.

Consequences

Simultaneous creates are not serialized by the preflight block check. Exported exception records survive deletion of the records they describe.
