fix: harden EPUB imports and Electron workspace navigation - #2208
Conversation
Importing a publisher EPUB (Nosy Crow, "The Talkative Tiger") produced:
print page numbers glued onto prose ("happily as 2Zoe threw", "Meep.3")
and standing alone as "120" / "iv" paragraphs; the cover, title page,
teaser, dedication and copyright page each emitted as "Chapter N"; and
chapter headings reduced to the <h1> subtitle ("A New Arrival") while the
book's table of contents carried the real label ("Chapter One: A New
Arrival").
The extractor now skips page-number markup (epub:type="pagebreak",
role="doc-pagebreak", or a page-break/page-number class), drops any
paragraph that is only an arabic or roman folio, records the document's
epub:type tokens so front/back matter (cover, titlepage, dedication,
copyright-page, toc, …) is skipped unless it is also body matter, falls
back to a title heuristic for untagged EPUB 2 files, honours
linear="no", never narrates the nav document, and titles each chapter
from the EPUB 3 nav or EPUB 2 NCX table of contents when present.
On the sample book: 9 chapters titled "Chapter One: A New Arrival" …
"Chapter Nine: Once Upon a Time", no glued digits, no lone page numbers,
no ISBN/dedication/teaser text.

…drop on evidence Greptile on debpalash#2208: - The nav/NCX document is a user-supplied zip member like any other: it now goes through the same per-entry and cumulative uncompressed-size guards as the spine (skipped when too large; what is read counts toward the shared budget). - TOC parsing accepts single- or double-quoted href/src attributes. - The bare-number fallback no longer touches prose: it applies only to documents that carry page-number markup, only to arabic numbers and strict lowercase roman numerals, so "1984" in an unpaginated book, a chapter numeral "IV" and a word like "civil" are narrated. Co-Authored-By: Claude <noreply@anthropic.com>

0ac30d7: all three Greptile findings addressed — nav/NCX members now go through the same per-entry and cumulative zip-bomb guards as the spine; TOC parsing accepts single- or double-quoted href/src; the bare-number fallback only runs for documents that carry page-number markup and only matches arabic numbers or strict lowercase roman numerals ("1984" in an unpaginated book, "IV", "civil" are narrated). Tests added for each; the sample book still yields 9 clean chapters. |

Normalize EPUB member-read failures.
At line 258, zipfile.ZipFile.read can raise zipfile.BadZipFile for a corrupt member or RuntimeError for an encrypted member, but the handler catches only KeyError. audiobook_import maps only ValueError to HTTP 400, so these failures escape as HTTP 500. Normalize these failures to ValueError for all EPUB member reads, including the OPF and spine reads, and add fail-before/pass-after regression coverage.

…mbers raise ValueError CodeRabbit on debpalash#2208: a landmarks nav ("Start of Content") linking a chapter before the toc nav could name it, and an NCX listed earlier in the manifest could beat the EPUB 3 nav. Section labels now come only from <nav epub:type="toc"> (a nav document without one is read whole), and nav labels take precedence over NCX regardless of order. Every member read goes through _read_member: a truncated, CRC-broken, encrypted or unsupported-compression member (BadZipFile / RuntimeError / NotImplementedError / EOFError) becomes the ValueError the import route already maps to a 400 with the reason; a malformed OPF likewise. Tests for both. Co-Authored-By: Claude <noreply@anthropic.com>

2b89fbe: CodeRabbit's two findings — section titles now come only from |
Opening Settings swapped the whole left column: the navigation, voice library and status bar disappeared and a different panel (brand header, section list, Back) took their place, so the app's main menu moved around between screens. The app shell now renders the main sidebar on Settings routes too; the Settings column keeps its section list and search but drops the duplicated brand header (the brand and window controls live in the main sidebar), and /settings follows the same narrow-window sidebar rules as the other secondary-panel workspaces. Co-Authored-By: Claude <noreply@anthropic.com>
In the expanded sidebar the main navigation was rendered under the voice library, so its vertical position depended on how tall the library happened to be, and it sat at the opposite end from where the compact rail shows it. It now sits directly under the header, above the library, with the status bar and Settings link unchanged at the bottom. Co-Authored-By: Claude <noreply@anthropic.com>

…for the rail On windows up to 1680px, opening a workspace that has its own side panel (Projects, Transcribe, Tools, Stories, Dubbing, …) shrank the main sidebar to a rail automatically, with no way to opt out. A persisted preference (Settings → Appearance → Keep sidebar expanded, stored with the workspace layout) now disables that; a workspace that shows the voice library itself still collapses the duplicate, and the explicit close button keeps working. The sidebar component carried its own copy of the rail/expanded logic with a component-local "force expanded" state, while the header toggle used the shared hook with store state — the two could disagree. The sidebar now consumes the hook. Strings in all 21 locales; hook test covers the preference, the library-owning route and the explicit close. Co-Authored-By: Claude <noreply@anthropic.com>

A valid self-closing page-break element such as <span epub:type="pagebreak"/> is added to _pagebreak_stack, but HTMLParser does not call handle_endtag for it. The stack therefore remains set and silently discards all narration that follows; implement handle_startendtag so self-closing non-void elements are immediately balanced.

Verified against Python HTMLParser: its default handle_startendtag calls handle_starttag and handle_endtag, so current parsing already balances self-closing pagebreak markers. Commit c9cac16 adds span and div regression cases; both pass and preserve following narration.

EPUB 3 navigation document required nav element EPUB 2 compatibility root-level anchors specification
💡 Result:
<search_synthesis>
In EPUB 3, the navigation document is a required component that provides human- and machine-readable navigation information, superseding the EPUB 2 NCX file [1][2][3]. Requirements for the nav Element: The navigation document uses the HTML nav element to define navigation structures [4]. When a nav element is used in this document (specifically when it includes the epub:type attribute), it is subject to strict content restrictions [5][6]: - It may contain an optional heading (h1-h6 or hgroup) followed by a single ordered list (ol) [6]. - No other elements are permitted as direct children of the nav element [6]. - Each list item (li) in the ordered list must contain either a single anchor (a) element or a span element, optionally followed by a nested ordered list (ol) for subsidiary content [5][6]. - The span element is used to label groups of links and cannot be used in leaf list items [5][6]. EPUB 2 Compatibility and Root-Level Anchors: - EPUB 3 publications may include an EPUB 2 NCX file for forward compatibility with EPUB 2 reading systems [1][2]. - Because EPUB 3 navigation documents and EPUB 2 NCX files use different mechanisms for identification in the package document—the manifest nav property for EPUB 3 versus the spine toc attribute for EPUB 2—they can coexist within the same EPUB 3 publication without conflict [2]. - EPUB 3 reading systems are required to ignore the NCX in favor of the EPUB 3 navigation document [2]. - Similarly, the EPUB 2 guide element is deprecated in favor of the landmarks feature in the EPUB 3 navigation document, though authors may still include the guide element for backward compatibility [1][2]. Regarding root-level anchors, the navigation document structure is hierarchical, based on an ordered list (ol) of items [5][6]. There is no requirement or specification for "root-level anchors" outside of this standard ordered list structure within the nav element [5][6]. Any top-level navigation items must be structured as list items (li) within the primary ordered list governed by the nav element [6][7].

Reject navigation documents without a <nav> element.
An EPUB 3 navigation document requires a <nav> element; EPUB 2 uses an NCX instead. This fallback scans unrelated root anchors, which can rename a spine document and trigger ancillary filtering. Treat the navigation as unavailable and add regression coverage.

EPUB imports preserve spoken text while removing marked print furniture. Electron keeps navigation available on Settings, places navigation above the voice library, offers a persistent expanded-sidebar preference, and prevents long Stories scripts overlapping generation controls.
