1. KumbhDoot: Mass Gathering Distributed Swarm

The KumbhDoot architecture is designed for extreme network density scenarios where tens of thousands of users submit requests simultaneously over degraded cellular infrastructure.

Architectural Properties:

• Local Fallback Inference: 1.5B/3B parameter quantized SLMs running locally on field gateways ensure essential query processing continues during internet dropouts.
• Multilingual Speech Pipeline: Phonetic transcription optimized for low-resource Indic regional dialects.
• Gossip State Consensus: Decentralized state synchronization among neighboring edge gateways.
