Versioning Architecture - Simple audit trail for V1.0: Track who, what, when, why for each change. Store before/after values in edits table. Manual restore if needed (create new edit with old values). Full versioning system (branching, merging, automatic rollback) deferred to V2.0+ unless users explicitly request it.
V1.0: Simple edit history sufficient for accountability and basic rollback.
V2.0+: Add complex versioning if users request "see version history" or "restore previous version" features.
