The book reader's word lookup used DictionaryService, a verb-conjugation
index plus ~200 hand-typed words: ordinary nouns like "taza" returned
nothing, and homographs always lost (tapping "como" in "como siempre"
gave the verb "comer" because the verb index is checked first).
Add a glossary phase to the books pipeline (build_glossary.py): every
distinct Spanish word is translated once, in its sentence context, by
the same Claude-Code-subagent LLM step the pipeline already uses for
chapter translation. English front matter is excluded by an ES==EN
paragraph-ratio heuristic. The glossary is bundled into book_<slug>.json
and is now part of the pipeline for every book.
In the app, Book carries the decoded glossary and BookReaderView resolves
each tap automatically through cache -> glossary -> DictionaryService ->
on-device LLM, citing which source answered so a curated glossary hit
reads differently from a best-effort AI guess.
book_olly-vol2.json regenerated with a 3,658-word glossary.

extract_epub.py was walking <p> only, but every "Vocabulario" section in
the Olly Richards EPUB lives inside <ul><li>...</li></ul>. That meant
the heading made it through but the entries didn't — 680 vocab lines
across 24 sections in this book were missing from the bundled JSON.
Audit (text-node owner by closest block ancestor) confirmed <li> is the
only silent drop: 5,260 nodes in <p>, 1,960 in <li>, 0 anywhere else.
No <h1>-<h6>, tables, or blockquotes in this EPUB at all.
Fix: walk find_all(["p", "li"]) in document order so bullet entries
slot in right after their "Vocabulario" / list heading. Re-extracted
(2,646 → 3,326 paragraphs), re-translated all 118 jobs in parallel
Claude Code subagents. translate_chapters.py prompt template now tells
subagents to keep bilingual `palabra = meaning` lines verbatim — both
sides already coexist on the line.
Bumped bookDataVersion to 2 so refreshBooksDataIfNeeded re-seeds.
Verified in simulator: all 13 chapter row sizes grew (e.g. ch6
18,295→20,951 chars).

New "Books" row in the Practice tab opens a library of bundled bilingual
books. Each chapter renders Spanish paragraph-by-paragraph; tap any
word for a definition sheet (DictionaryService with on-device AI
fallback), or toggle the toolbar button to swap to the pre-computed
English translation inline.
Local-only Book + BookChapter SwiftData models added to the local
container schema (reset version bumped to 5). DataLoader.seedBooks
walks the bundle for `book_*.json` resources, so future books drop in
without touching app code — just bundle a new JSON and bump
bookDataVersion.
First book: Olly Richards' "Spanish Short Stories For Beginners
Vol 2" — 13 chapters, 2,646 paragraphs, bilingual.
Scripts/books/ is the repeatable pipeline for future EPUBs:
extract_epub.py → translate_chapters.py (per-chapter resumable jobs) →
bundle_book.py. Translation is done by parallel Claude Code subagents
reading per-job input files and writing output files — no API key
required, matching the pattern used for the textbook vocab vision
pass. See Scripts/books/README.md for the full how-to.
