- Add to PluginManifest
- None = not declared (use VoiceLister fallback)
- () = explicitly no static voices
- Non-empty = static catalog available without Engine instantiation
- Update get_voices() to check manifest first, fall back to Engine
- Declare 54 Kokoro voices and 10 SuperTonic voices in manifests
- Remove hardcoded voice lists from engine.py files
- Engine.listVoices() now returns [] (manifest is source of truth)
- Clean up dead create_pipeline() kwargs (sample_rate, auto_download, total_steps)
- SuperTonic plugin uses internal defaults
- total_steps is per-request parameter via Pipeline.__call__() kwargs
- Add clear_preview_pipelines() for resource cleanup
- Fix test mocks to override listVoices()
- Update Architecture Amendment #1 doc
Task 1: Replace hardcoded VoiceLister bypass in get_voices()
- Use PluginManager → Engine → VoiceLister instead of direct imports
- No more hardcoded imports of plugins.kokoro.engine / plugins.supertonic.engine
Task 2: Remove SuperTonic Plugin dependency on legacy backend
- Create self-contained plugins/supertonic/pipeline.py
- Plugin no longer imports from abogen.tts_backends
Production code now has zero imports from:
- abogen.tts_backend
- abogen.tts_backend_registry
- abogen.tts_backends
Implement first TTS plugin using new Plugin Architecture:
- plugins/kokoro/: Plugin package with manifest and entry point
- plugins/kokoro/engine.py: KokoroEngine and KokoroSession adapters
- Wraps existing KokoroBackend without modifying it
- Implements VoiceLister capability
- Satisfies Engine/EngineSession protocol
- Passes all 163 contract tests
Tests:
- Plugin loading through Plugin Loader
- Manifest validation
- Engine creation and lifecycle
- Session synthesis and dispose
- VoiceLister capability
15 new tests for Kokoro plugin.
