Architectural review of the recent-profile-identity task found no structural changes needed: the DB join lives in the ProfileQuery adapter behind the ListRecentProfiles use case and controller, and the client account cell follows the established CommonJS + acceptance-render-adapter pattern for DOM-free testing. Committing the tool-written mutate4javascript manifests and the gherkin-mutator mutation stamps/manifests produced by the verification run. By architect.
