Keep Data Quality work records free of custom fields

Context

Custom values belong to designated business records rather than duplicate-processing state.

Decision

Duplicate and merge work records declare no custom-field capability; merge previews resolve the custom values already owned by their contact or organization participants.

Alternatives Considered

Add custom fields to rules and merge history. The cited capability standard requires explicit object support, which these records do not declare.

Consequences

Duplicate groups still need metadata registration for attention, with custom-field capability kept separate.
