- Add EBOOK_REFACTOR_PLAN.md with 856 lines of detailed instructions
- Split 1,350-line ebook.go into focused single-responsibility files
- Zero API changes, only code organization for maintainability
- Phase-by-phase safety checkpoints and rollback procedures
Target file organization after refactor:
- media.go (~600 lines): Media CRUD + metadata
- search.go (~80 lines): Query and search operations
- matching.go (~200 lines): Book matching and sync operations
- ebook.go (~150 lines): SetupRoutes only
Plan ensures AI can implement without breaking any functionality.
