🏗️ **Major Database Schema Refactoring** **Problem Solved**: Eliminated model duplication and multiple sources of truth by: - Removed duplicate models (`internal/models/content.go`) - Replaced inlined schema strings with sqlc-generated setup functions - Implemented database-specific schemas with proper NOT NULL constraints **Key Improvements**: ✅ **Single Source of Truth**: Database schemas define all types, no manual sync needed ✅ **Clean Generated Types**: sqlc generates `string` and `int64` instead of `sql.NullString/sql.NullTime` ✅ **Schema-as-Query Pattern**: Setup functions generated by sqlc for type safety ✅ **Database-Specific Optimization**: SQLite INTEGER timestamps, PostgreSQL BIGINT timestamps ✅ **Cross-Database Compatibility**: Single codebase supports both SQLite and PostgreSQL **Architecture Changes**: - `db/sqlite/` - SQLite-specific schema and setup queries - `db/postgresql/` - PostgreSQL-specific schema and setup queries - `db/queries/` - Cross-database CRUD queries using `sqlc.arg()` syntax - `internal/db/database.go` - Database abstraction with runtime selection - `internal/api/models.go` - Clean API models for requests/responses **Version Control System**: Complete element-level history with user attribution and rollback **Verification**: ✅ Full API workflow tested (create → update → rollback → versions) **Production Ready**: Supports SQLite (development) → PostgreSQL (production) migration
