[Incident][108dev] Avatar speech token broker unavailable (missing speech/AI runtime config)

[Cataldir]

Summary

Avatar speech and response flows are degraded in 108dev due to missing runtime configuration.

Evidence

• GET /api/avatar/speech/session-token returns 503
• Response detail:
  • Speech token broker unavailable: Speech broker is not configured. Set SPEECH_RESOURCE_ID and SPEECH_REGION.
• Runtime env on tutor-avatar-108dev shows empty:
  • SPEECH_RESOURCE_ID
  • SPEECH_REGION
  • PROJECT_ENDPOINT
  • MODEL_DEPLOYMENT_NAME
• GET /api/avatar/health and /ready return 200 (service up but partially broken)

Impact

• Speech token brokering fails for Avatar UI.
• Avatar conversational path is at risk due empty AI endpoint/deployment config.

Proposed remediation

1. Set SPEECH_RESOURCE_ID + SPEECH_REGION on avatar app.
2. Set PROJECT_ENDPOINT + MODEL_DEPLOYMENT_NAME on avatar app.
3. Add deploy guardrail checks for these required vars.
4. Add post-deploy avatar smoke checks (/speech/session-token, /response).
