### November 2025 Update
- `book.id`, `section.id`, and `section.num` are now integers instead of strings.
- `reader` has been replaced with a `readers` array. No entries currently have more or less than 1 reader.
- `text` has become `source`. The `text` field is now a direct link to the plaintext content of the book, if such content exists; `null` otherwise. 250K entries (~53%) have plaintext source available.
