How the Swarm SDK uses Extended Triple Diffie-Hellman (X3DH) with ML-KEM-768 adaptation for async drone-to-drone session establishment — prekey bundle construction, one-time prekey consumption, Fleet CA bundle verification, and the transition from shared secret to Double Ratchet forward secrecy.

How the Swarm SDK generates, distributes, and tracks OneTimePreKeys for X3DH session establishment — including OTP exhaustion handling, SignedPreKey rotation, and the gossip-mesh key bundle protocol.
How we ingest and refresh 208 federal regulatory datasets across 45 agencies using Cloudflare Workers cron, delta detection, schema drift handling, and per-source retry budgets — the ETL behind the Federal Regulatory Data Hub.
How the Swarm SDK MeshTransport layer achieves reliable frame delivery over lossy drone radio links: sliding window ARQ with selective ACK, EWMA RTT estimation, transparent fragmentation and reassembly for Sealed Sender envelopes, multi-channel bonding across 2.4GHz and 5.8GHz radios, and performance benchmarks on STM32H7 and Jetson Nano.
Swarm SDK gossip mesh: bounded fanout routing, message deduplication, and network partition handling
How the Swarm SDK implements a gossip mesh for drone swarms: epidemic broadcast with k=3 fanout, UUIDv4 sliding-window deduplication across a 1000-ID VecDeque, Lamport clock causal ordering for key management messages, TTL hop limiting with 3-hop lossy-channel headroom, and anti-entropy reconciliation for post-partition recovery — with STM32H7 and Jetson Nano benchmarks.
