Direct answer
The curated app exposes 15 tools: seven read/start/plan actions, five ordinary project or metadata writes, one explicit accepted-chapter replacement, and two publication rendering actions. Finalization is the only action that freezes a new immutable snapshot.
Read and orient
list_books, get_book_status, start_writing_session, get_chapter_packet, catch_me_up, and get_publication_status load bounded owner-scoped state.
Create and progress
create_book, save_book_blueprint, accept_current_chapter, extend_book, prepare_book_for_review, and save_publishing_package make explicit, idempotent changes.
Replace and finalize
replace_accepted_chapter replaces earlier accepted content and leaves the cursor unchanged. finalize_publication freezes an approved snapshot. rerender_publication_package queues fresh files for the same snapshot without another unique-package charge.
Frequently asked
Can a card call a mutation itself?
No. Cards render state and open bounded BookWriter links; mutation tools remain under the model and confirmation flow.
