## Stack Context This is the Nova UI half of Slack account linking. The paired API and database work is [mono#2650](https://github.com/supermemoryai/mono/pull/2650). ## What? - Preview the Slack and signed-in Supermemory identities before linking. - Block accounts that are not already organization members. - Require explicit confirmation when replacing an existing mapping. - Handle account switching and invalid, expired, used, success, and retry states. ## Why? Users whose Slack and Supermemory emails differ need a clear, secure way to confirm their identity. The page makes the identities and organization membership requirement explicit before creating or replacing a stable mapping.
