ID3 provenance tags (synthetic speech, generator, version, date, opt-in
voice name) on magazine MP3/ZIP/EPUB exports via a stream-copied temp copy;
verify endpoint and CLI; AudioSeal tier is a documented stub.

Also reuses the existing magFmtClock for the contents list (the duplicate
tripped the frontend collision gate).

Magazine P1:
- Images shown automatically during playback (assign_images_to_articles
links each figure to the article whose column it falls in; the client
shows the last image reached in reading order as playback advances).
- "Play all articles" queues every approved article and advances
automatically at the end of each rather than stopping.
- Word-level highlighting, explicitly documented as an ESTIMATE (no
forced-alignment/timestamp source exists): each word's share of the
sentence's real measured audio duration is proportional to its
character length. A checkbox turns it off; sentence highlighting
(measured, not estimated) is unaffected.
- Driving mode: full-screen overlay, two oversized controls, reuses
whatever is already playing/queued.
- Sidebars/pull-out boxes excluded from narration automatically
(mark_sidebars: an anomalously narrow column vs. the page's regular
grid). Fixed a real defect found while building this: a full-width
headline was left in the column-width analysis and could bridge two
genuinely separate columns into one, hiding a real sidebar column
entirely -- caught by a failing test before the fix.
Second OCR engine + fallback ladder:
- KDL Frontier Parser nano wired in via vision_ocr_page_chain (ordered
engine list, first usable result wins, tesseract last resort).
Confirmed live: ~3x faster than Baidu (~12s vs ~40s/page) but returns
plain text with NO coordinate markers, unlike Baidu's labeled regions.
_whole_page_region treats the whole response as one ambiguous
full-page block (gated by ocr_quality_score) rather than discarding
usable text just because it lacks layout structure.
OCR engines page + a real UI bug:
- The OCR & Document Parsing page had no .s-engines-page[data-page="ocr"]
markup at all -- renderLocalContainers already supported an OCR grid
generically, but $('dc-grid-ocr') was always null, so the card grid
silently never rendered. Added an Active OCR Engine panel mirroring
Active Language Model exactly, plus the Local grid -- both configured
engines now appear as ready-made cards, no "Add Custom" dialog needed.
- Fixed the audiobook pipeline's "Previous/Next" nav bar bleeding into
every .section-head in the document (confirmed live on the Engines
page: a "Cast Audiobook" button and "STEP 1/8" hint that made no sense
there). Changed from a blocklist (naming each unrelated section as
noticed) to an allowlist of the pipeline's three actual destinations.
Verified live end-to-end: play-all queue building and manual advance,
word-span markup, driving-mode toggle, OCR page showing both engines as
local cards, zero stray nav bars on the Engines page, no console errors.
20 new backend tests (156 total in the magazine module).

A page needing OCR (or whose already-extracted text -- native or
tesseract alike -- scores as mostly garbage via ocr_quality_score) is
now escalated to a connected vision OCR engine before falling back to
tesseract. Falls back automatically on any failure (unreachable engine,
timeout, unparseable output); never fatal to ingestion.
Verified live against ocr-baidu-unlimited-ocr on a real 28-page scanned
c't magazine excerpt (Epson ES-580W, no scanner OCR): every garbled
article title tesseract produced ("K | soll Arbeit abnehmen", ". |",
"@)X", "Owns mee") was replaced by the real headline ("1. Irrtum: KI
ist ein allgemeiner Jobkiller", etc.), and furniture detection jumped
from 44 to 151 blocks because the engine labels running headers/
footers/page numbers directly instead of needing fuzzy post-hoc
matching. 26 of 28 pages used the vision path; the remaining 2 fell
back to tesseract automatically.
Also fixes two real defects found investigating the same real-world
data, both regression-tested against the actual garbled strings
observed:
- Exact-match repeated-line detection (running header/footer) silently
failed once tesseract OCR'd the same line differently each time --
cluster_running_furniture fuzzy-matches near-edge blocks instead.
- ocr_page() built one Block per OCR text-LINE rather than per
paragraph, so a single anomalous line (a chart number, scan noise, a
wrapped headline continuation) could independently trigger title
classification -- now grouped by paragraph like the native PyMuPDF
path, using the paragraph's median line height rather than its total
bbox height for font size.
A vision-engine label (footer/title/page_number/caption) is trusted
outright and skips classify_blocks' font-size heuristics entirely,
since the engine gives no reliable font metric; an ambiguous "text"
region gets a synthesized estimate from its paragraph area and length
(estimate_font_size_from_area) and still goes through normal
classification.
Off unless vision_ocr_url/vision_ocr_model are configured
(vision_ocr_enabled setting, default on if reachable); per-request
override via the ingest endpoint body. Default engine URL uses
host.docker.internal, confirmed live -- the OCR container runs on its
own Docker network, not dgx_net, so a container-name default would not
resolve from the app container.
28 new tests (136 total in the module). ocr_quality_score is
deliberately coarse and documented as such: it catches text that is
mostly symbol noise, not a plausible single-word misread inside an
otherwise normal sentence (confirmed live: a misread "KI" -> "K |"
still scored 0.81) -- that class of error needs a dictionary or
language-model check, out of scope here.

Voice consistency:
- Read back each voice's pinned seed (Seed Finder / Batch Seeds) on every
generation. The seed was saved to voice metadata but only ever read by the
Seed Finder's own benchmark path, so all per-voice seed pinning was inert.
- Stop coercing the "voice_design_playback" stability profile back to
"voice_clone". The pseudo-backend key isn't a real routing target, so the
backend-name normalizer silently rewrote it — reintroducing the hardcoded
seed:0 that profile exists to avoid, overriding every per-voice pin.
- Apply the accent clause on every line, not just at voice-creation time,
and reorder the instruct so emotion leads and accent trails (Qwen3-TTS
doesn't reliably follow multiple conflicting instructions).
- Pass an explicit language to Voice Design instead of leaving it on "Auto".
Audio effects:
- Add a limiter after compressor makeup gain. Makeup gain pushed peaks to
~1.9, and the final hard clip turned that into broadband distortion that
swamped the rest of the chain.
- Cascade highpass/lowpass 3 stages each (~18 dB/octave). Single-pole
filters were too gentle to band-limit speech audibly.
- Add a Bandpass control and wire it into the Telephone/Radio presets —
compression alone never sounded like a phone; band-limiting is the
defining trait.
Persona / Try It Out:
- Disable "Apply character persona" with an explanatory tooltip when the
voice has no persona saved, and error clearly server-side instead of
silently no-op'ing. Persona is typed manually per voice, never auto-filled.
- Stop dropping applyPersona in the chunked generation path (>200 chars).
- Populate the Voice Design dropdown from the user's own library rather than
filtering the engine's discovery list, which never contains custom voices.
Navigation and library:
- Use pushState instead of replaceState so browser Back/Forward step through
in-app navigation instead of leaving the app entirely.
- Show real dialogue line counts in the character sidebar instead of the
capped reference-quote count (which showed a misleading uniform "12").
Also fixes a crash in /api/transcribe-bytes that referenced an undefined
source_id in its cleanup path.

Introduces the new Studio section (Source -> Characters -> Voices ->
Perform & Export) that reuses the existing Read Aloud/Library/Script
Rehearsal code via DOM reparenting instead of duplicating it, and rolls up
a long tail of bugs found while producing a real audiobook through it:
umlaut-eating name sanitizers, a voice picker that mispositioned itself and
capped results at 60, PDF pagination silently breaking on trimmed \f
markers, a race letting stale audio keep playing after a new line was
clicked, an alias-overlap bug that could silently redirect a voice/image
save onto the wrong character, voice design failing outright during brief
TTS backend restarts instead of retrying, sparse cast entries defaulting to
English/wrong gender, and a reassigned voice never reaching an already-open
Stage session or invalidating its cached audio. Also adds a persistent
per-line audio cache, audiobook export browsing/download, and an inline
voice-design prompt editor. Full details in CHANGELOG.md.

- Added a new 'Table View' button to the library sort bar.
- Implemented a CSS grid layout to display voice properties in a high-density table.
- Added sortable column headers (Name, Lang, Gender, Speed, dBFS, Length, Rating, Source, Seed, Note, Tags, Active).
- Aligned CSS grid to account for the bulk edit checkbox injection.
- Added drag-and-drop profile image support to the Inspector's large avatar.
- Ensured picture updates instantly synchronize across the List, Table, and Inspector views.
Previously: container names and dynamic card URL overrides only
written to localStorage — lost when accessing from a different
browser or after clearing browser data.
Now:
- engine_container_names added as persisted settings key (dict)
- All container name inputs tagged data-cn-key for loadSettings() lookup
- loadSettings() restores container names + dynamic URLs from server
- settings.js exposes _saveEngineContainerNames() and
_saveEngineLocalUrls() globally so engines.js / ai-backends.js
can call them on every input event
- Static cards (ai-backends.js initStaticDockerManagement): reads
saved name from engine_container_names first, localStorage fallback
- Dynamic Docker stack cards (engines.js): same priority for both
URL and container name; both write to server on change
