Complete the Language enum unification (commit 0dc491e) for the PyQt
GUI, which was left resolving languages from kokoro letter codes
(voice[0]) while domain and WebUI already used Language enums.
- selected_lang is now always a Language enum: voices resolve via
language_for_voice_id(), profiles via resolve_profile_language()
- kokoro letter->Language mapping stays in the engine (new public
language_for_code()); the Language.from_code() domain shim is removed
- legacy profile files with letter codes ("a", "e", ...) are tolerated
only at the profile read boundary; new profiles save ISO codes
- conversion.py letter comparisons replaced with enum comparisons, and
SynthParams lang_code= -> language= (would TypeError at runtime)
- subtitle dropdown enabled for all languages; word-count and
highlighting modes restricted to English with auto-switch to Sentence
- tests: engine mapping + profile language resolution added; 1566 pass
- Create domain/text_utils.py with canonical calculate_text_length
(strips chapter markers, voice markers, metadata tags)
- Remove calculate_text_length from utils.py and subtitle_utils.py
- Update all imports to use domain.text_utils directly
- Create application/chapter_selection.py with build_chapter_payload()
(orchestrates preselection + character count + safety net)
- Replace manual chapter logic in form.py with build_chapter_payload()
- 22 new tests for text_utils and chapter_selection (1550 total)
Voice cache is now initialized lazily by domain's initialize_voice_cache()
in PipelinePool.get() — downloads only needed voices per request instead
of all ~100 kokoro voices at service startup. Reduces redundant downloads
and unifies initialization path for all UIs.
- Add expand_metadata_aliases() for concept fan-out (series→5, author→2,
description→2, tags→3 keys)
- Replace _normalize_metadata_tags in webui/service.py with
normalize_metadata_map from domain
- Replace _normalize_metadata in epub3/exporter.py with
normalize_metadata_map from domain
- Replace manual fan-out in form.py with expand_metadata_aliases()
- Rewrite metadata_overrides.py to use expand_metadata_aliases()
- Remove unused normalize_metadata_casefold import from exporters.py
- 19 new tests for expand_metadata_aliases (1528 total)
Move build_narrator_roster, build_speaker_roster, match_configured_speaker,
apply_speaker_config_to_roster, prepare_speaker_metadata from
webui/routes/utils/voice.py to domain/speaker_metadata.py.
- prepare_speaker_metadata now accepts optional inject_recommended callback
for UI-specific voice enrichment
- 47 new tests in test_domain_speaker_metadata.py
- All 1509 tests pass
- Add formula_from_profile, resolve_profile_voice, resolve_voice_setting, resolve_voice_choice to domain/voice_resolution.py
- Add build_voice_catalog, filter_voice_catalog to domain/voice_catalog.py
- Update webui/routes/utils/voice.py to import from domain
- Update webui/routes/utils/form.py and voices.py to import from domain directly
- Update synthesize.py to use domain resolve_voice
- Add 29 tests for voice resolution functions
- Move stored_integration_config(), build_audiobookshelf_config() to domain/settings_core.py
- Remove legacy fallback from stored_integration_config() (only config[integrations])
- Add load_audiobookshelf_config() as combined entry point
- PostConversionHooks reads config directly via stored_integration_config()
- WebUI imports from domain/settings_core instead of webui/routes/utils/settings
- Remove duplicate _build_abs_config() from PostConversionHooks
- Remove dead audiobookshelf code from infrastructure/exporters.py
- Remove duplicate audiobookshelf functions from webui/service.py
- Fix OutputFormat enum serialization in output_layout_service.py and conversion_executor.py
(f'{enum}' gave 'OutputFormat.WAV' instead of '.wav')
- Mock spaCy in test_returns_at_least_one_segment instead of loading real model
- Add 28 tests for PostConversionHooks and build_audiobookshelf_config
- synthesize.py: import to_float32 from domain.audio_helpers instead of duplicate
- Revert all log levels back to INFO (user controls verbosity via --log-level)
- form.py: convert language string to Language enum at all entry points
- conversion_request.py: add _coerce_enums() for defense-in-depth
- synthesize.py: fix NameError (lang -> language) in preview pipeline
- voice.py: render LANGUAGE_DESCRIPTIONS keys as .value strings for Jinja
- dashboard.js: open file picker on dropzone click
- api.py: add logging to preview endpoint for debugging
- Deleted _prepare_tts_context() (104 lines of duplicated logic)
- Replaced with direct build_tts_context() call in run_conversion()
- Fixed _finalize() to use raw fields (generate_epub3, epub3_book_id)
- Removed _MockJob antipattern
- Updated tests to use raw normalization_overrides field
- ConversionRequest uses raw fields instead of PronunciationConfig/Epub3ExportConfig
- Added speakers field to ConversionRequest
- Rewrote collect_required_voice_ids(), initialize_voice_cache(),
job_voice_fallback(), chapter_voice_spec(), chunk_voice_spec()
to accept ConversionRequest instead of job
- PipelinePool.get() now takes request= instead of job=
- Updated all tests to use ConversionRequest interface
- 1493 tests passing
- conversion_pipeline.py: new spacy_pre_tts_segmentation() function
- Handles: condition checks, language exclusion, split_pattern override
- Executor: integrated spaCy pre-TTS before each synthesize_text() call
- 6 new tests for condition checks and fallback behavior
- English excluded from pre-TTS (spaCy only for post-TTS subtitles)
- Fallback to regex when spaCy unavailable
- MarkerCollector: SRP extraction from executor (observation, not execution)
- Outro marker: executor now records outro as chapter marker
- Voice format: chapter voices [{provider, voice}], chunk voice {provider, voice}
- _finalize(): build_metadata_payload() + metadata.json + record_override_usage()
- ffmetadata: voices list → comma-separated string
- EPUB3: ChunkOverlay.voice = dict, _render_chunk_inline handles dict format
- 8 new tests: multi-speaker, ffmetadata format, EPUB3 format
- Updated existing tests for new voice format
- Import run_tts_segment_loop (used in pyqt/conversion.py)
- Use build_tts_context() instead of manual _MergeJob + TTSContext
- Drop unused AudioSink import
- Remove 77 unused imports across domain/application/runner files via ruff
- Add # noqa: F401 to re-exports used by tests and debug_tts_runner
- Fix build_tts_context: usage_counter uses 'is not None' instead of truthiness
- Fix test assertions: compiled rules use 'replacement' key not 'pronunciation'
- Add re-exports: _compile_pronunciation_rules, _merge_pronunciation_overrides
PluginManager.discover() used a relative path 'plugins', which resolved
against the CWD. When launched from a desktop shortcut the CWD is ~, so
the plugins directory was never found and no voices appeared in the list.
Fall back to the project-relative plugins path when the default relative
path doesn't resolve.
- subtitle_generation: split multi-sentence FakeToken into separate entries
- conversion.py: add missing run_tts_segment_loop import
No changes to spacy_utils or Language enum.
