Architecture Decisions and Open Questions

Accepted decisions, scaling triggers and unresolved programme dependencies for the live-call blueprint.

BlueprintVersion 0.25 Aug 2026

Accepted decisions

  • Android-first Flutter application with live Urdu audio-video consultation.
  • LiveKit/WebRTC is a baseline pilot component, not deferred infrastructure.
  • Continuous media transport with adaptive selected-frame reasoning.
  • Cascaded STT → reasoning → TTS with transcript and interruption.
  • Frontier reasoning model as primary analyst.
  • Local documents, field context and policy as primary operational authority.
  • Hierarchical retrieval and controlled internet research.
  • Narrow deterministic verification for exact/legal/safety claims.
  • Human review by risk, including officer join and warm handoff.
  • PostgreSQL-first application with object storage and a worker.
  • Hybrid controlled pilot with a sovereignty path.

Conditional decisions

ComponentAdopt when
Multi-node LiveKit/TURNConcurrency, failure-domain or regional requirements justify it
LangGraphDurable resumable workflows exceed simpler orchestration
QdrantPostgreSQL retrieval becomes a measured bottleneck
Kafka/RedpandaDurable event fan-out/backlog exceeds worker queue
Kubernetes HAAvailability and scale commitments justify complexity
Sovereign VLM/STT/TTSPolicy, economics or strategy justify local serving
Full-call recordingApproved purpose, consent, security and retention are established

Open programme questions

  1. Which districts and mobile networks represent the pilot?
  2. What minimum bandwidth/device profile is supported?
  3. Will LiveKit be managed, government-hosted or hybrid during the pilot?
  4. What percentage of calls may relay through TURN?
  5. Which views and frame quality thresholds are crop/condition specific?
  6. Who may join a room and during which hours?
  7. What exact consent and recording policy applies?
  8. Which data may leave government infrastructure?
  9. What numerical go/no-go thresholds apply by risk class?
  10. What cost per completed live advisory is acceptable?
