Each line: a book, how many lines of it, the sha256 of those lines, the hash of its last line.
Bytes: the file as stored (UTF-8, no BOM, nothing re-encoded or normalised); a line ends with LF (0x0A); the sha256 of N lines covers lines 1..N, each with its final LF (a CR before it stays); a last line without LF is not counted yet
