Worked resolution cases
An incoming contact has the same verified work email as an existing archived contact. Link and restore or update the existing identity; do not create a second record because the first is archived.
An account name matches exactly, but its canonical domain and country differ. Route to review as a possible namesake or subsidiary. Name similarity cannot overcome the domain conflict.
A company has rebranded. The old record contains the former domain, active opportunities, and a documented redirect to the new canonical domain. Link with the rebrand evidence and preserve the old domain as an alias.
A contact uses a consumer email and shares a common name with two existing contacts. Reject or review until employer or another stable identifier is available.
