Resolve chapter labels from EPUB nav entries (when present) and from the
first in-document h1/h2/h3 heading, parse roman-numeral and "Chapter N"
labels into numeric chapter indices, and generate stable IDs of the form
chapter-NN with -part-NNN suffix when a chapter exceeds max_words. The
chunker now operates on cleaned body text, distributes id="Page_*" page
anchors per part via inline markers extracted before splitting, and
supports a configurable overlap_words evidence window between adjacent
parts of the same chapter. Reclassify body sections whose chapter label
matches contents/transcriber-notes/license/colophon tokens so they leave
the body stream by default. Strip <head>...</head> from HTML body
extraction to stop the <title> tag from duplicating heading text in the
chunk markdown.
Real Lefevre EPUB now detects all 24 roman-numeral chapters with stable
chapter-NN IDs, distributes Page_N anchors across multi-part chapters,
and reclassifies Contents and Transcriber's Notes out of body
(role histogram body=67, cover=1, header=1, toc=1, notes=1, footer=2).
82 tests pass.

Parse META-INF/container.xml and the OPF package document, then iterate
documents in spine reading order instead of archive-name sort. Classify
each spine item (body, cover, nav, toc, header, footer, notes, license,
auxiliary) and exclude non-body sections by default; include_non_body=True
opts them back in for inspection. Capture OPF book metadata (title,
creator, language, subjects, rights, identifier, source_url, modified)
onto every chunk and propagate it through source artifact provenance.
Preserve the legacy zip-without-OPF fallback for malformed EPUBs.
Real Lefevre EPUB now yields 148 body chunks in spine order (was 155
mixed, archive-sorted) with cover=1, header=1, footer=4 detected and
dropped. 78 tests pass.
