## Interactive bots

New bot capabilities beyond passive transcription:
- **Speak** — TTS playback into meetings via new `tts-service` (OpenAI-compatible `/v1/audio/speech`)

## Recording pipeline

- Full recording storage with MinIO (S3-compatible) and local filesystem backends
- Incremental upload during meeting via WhisperLive durable spool
- Inline range streaming for playback
- Post-meeting aggregate transcription from recordings
- API: \`GET /recordings\`, \`GET /recordings/{id}\`, \`GET /recordings/{id}/media/{id}/download\`, \`DELETE\`
- Browser audio flush/persist on leave for both Google Meet and Teams

## Deployment

- **Vexa Lite** — single-container all-in-one deployment with supervisord, process orchestrator, CPU transcription (\`docker/lite/\`)
- **Process orchestrator** — spawn bots as local Node.js processes for Lite mode (\`ORCHESTRATOR=process\`)
- Multi-arch Docker builds (amd64 + arm64)

## Webhooks & hooks

- HMAC-SHA256 signed webhook delivery with exponential backoff retry
- Generic post-meeting hooks system (\`POST_MEETING_HOOKS\` env var) for billing/analytics integrations
