Studio -> Magazines: library, contents tree grouped by section with
confidence/pages/listening-time/audio status, the Stage D review
screen (tick/untick layout blocks, correct title/author, approve or
reject), a reflowed article view with click-to-seek sentence
highlighting, a linked original-page view showing the source bounding
box, and a podcast panel (2-3 host pickers, script generation,
turn-by-turn playback).
Wired into the existing lazy-module system (module-manifest.json,
loader.js, nav.js) rather than a separate app. Reuses /api/tts-preview
for both narration and podcast turns -- no new audio pipeline.
Fixes found building this:
- The pane toggle used role="tab" without the full ARIA tabs pattern
(aria-selected, roving tabindex, arrow-key nav) -- fails WCAG 2.2 AA
and hid the buttons from role-based tooling. Replaced with a button
group + aria-pressed, matching the plain-click interaction it
actually has.
- Print layout cues ("(continued on page 8)") were being sent to TTS
verbatim -- narration would have spoken the parenthetical aloud.
Stripped from the narration copy only; layout.json keeps the
original for the review screen.
- has_podcast now comes from the articles listing so opening an
article without a generated script skips a doomed GET instead of a
routine 404 on every open.
Verified against the real API contract with Playwright (library,
review pre-selection, approval, sentence highlighting + PDF-page
linking, podcast approval gate, zero console errors across the flow)
and manually end-to-end against a real ingested fixture, screenshots
included. Full suite: 94 Python tests, 33/34 desktop Playwright tests
(one unrelated pre-existing flaky DOM-count assertion).

Magazines break the audiobook pipeline's assumptions: several unrelated
articles share a page, columns run in parallel, adverts and sidebars
interrupt body copy, and a feature routinely jumps twenty pages to its
tail. Narrating page-by-page walks out of an article mid-sentence and
into an advert, so the canonical object is the article, not the page.
core/magazine.py reconstructs articles from a flat PDF: PyMuPDF extracts
blocks with bboxes and font metrics, tesseract supplies a TSV fallback so
scanned pages join the same column grouping, blocks are classified and
ordered column-major, and articles are anchored by the parsed table of
contents with "continued on page N" tails linked back.
routes/magazine.py adds 13 endpoints. Ingestion is a restart-safe
background job. Nothing is narrated until a human approves the
boundaries; podcast generation refuses unapproved articles.
Podcast mode renders an approved article as a 2-3 host discussion using
the configured LLM and voices the user picks, alongside narration rather
than instead of it.
Verified end-to-end over HTTP on a synthetic 8-page issue: the feature
came back as pages [3, 8] with its jump tail absorbed and the advert page
excluded, and an image-only rendering recovered all 47 blocks via OCR.
44 new tests; full suite 90 passing.
The Studio UI is not built — this is reachable only via the API.
