Sub-ticket of MARS-198 Audit dormant/zero-auth user cohort for re-deletion: the 82 June-20-purge users confirmed zero auth footprint (0 login attempts in 14 days, scan 2026-06-26) are a clean re-delete candidate set; widen the audit to ALL dormant/never-onboarded users (active studentAssignment but no auth reality) and produce a re-delete vs keep decision per the 3-bucket auth-reality rule (ever-signed-in / recent-attempts / zero-footprint). Deferred by Elazar 2026-06-26 to be done later. Hold the actual soft-delete for Elazar go (bulk real-user op). · mars
