 # ADR-0092: Identity-table write guard — engine-enforced `managedBy: 'better-auth'`, with sys_user profile fields as the first whitelist
 
-- **Status:** Proposed
-- **Date:** 2026-07-10 (proposed) · 2026-07-11 (revised: D2 generalized from a sys_user-only hook to a registry-driven guard over every better-auth-managed object, per review)
