- Pipeline-down fallback: dialplan plays gogo-fallback after a failed
AudioSocket (§15) + script to synthesize the Bosnian prompt via TTS
- Voice heartbeat file → /health/voice endpoint + live status in admin panel
- Retention job also purges stale call registrations; chat sessions metered;
100%-usage super-admin alert email (GOGO_ADMIN_ALERT_EMAIL)
- .env.example, docs/DEPLOY.md (compose stack, GPU node, backups pg_dump,
update procedure, security notes)
- §16 Definition of Done as an automated test: softphone-style call → fake
partner availability → request pushed → webhook confirm → console SMS
- M0 PoC scripts: STT accuracy harness (CER/WER + spoken-digit check; dry-run
verified with espeak-ng samples + faster-whisper small on CPU — phone number
extracted exactly), TTS bake-off (Azure vs ElevenLabs, latency+cost), and
end-to-end latency smoke test speaking real AudioSocket to the live pipeline
