Recent Updates

• Replace eslint+prettier by biomejs to optimize speed.
• Resolve lint, build, and test failures across voice, workspace, library, and composio.
• Add first-class transport, auth, versioning, and BYOK support across all integrations.
• Add AI provider ranking system with ranking-driven model selection.
• Add @lssm-tech/lib.voice package for TTS, STT, and conversational voice.

Notes

• TTS/STT interfaces are adapter boundaries — keep them provider-agnostic.
• Audio processing must stay streaming-compatible (no full-buffer-only APIs).
• Depends on contracts-spec and contracts-integrations.

The exported ContentBrief is a structural narration input port owned by Voice. Content-generation briefs bind directly through the existing VideoGenerator composition; Voice no longer imports the content-generation domain. Required fields and accepted optional fields retain their existing shape.
