- LeadHistory entity (UUID PK, plain Long FKs — no FK constraints to allow lead deletion/conversion) - LeadHistoryEventType enum with human-readable labels - LeadHistoryFieldRegistry: single source of truth for ~55 tracked Lead fields; adding a field is one line - LeadFieldDescriptor record (key, label, category, extractor) - LeadHistoryService: snapshot/diff pipeline, **************** paginated+filtered findHistory, distinctFields/Actors for filter dropdowns - LeadHistoryDTO with nested ActorDTO; all Long IDs serialized as String for CockroachDB JS precision safety - LeadService: history hooks on create, update, delete, assignLead, assignLeadAccount, unassignLeadAccount
