Poison-resistant, Byzantine-fault-tolerant shared chat memory for LangChain agent swarms — one prompt-injected agent can't corrupt the shared history.

Bit-exact Byzantine-fault-tolerant state layer for federated learning and edge/defence swarms. Three layers — OR-Set CRDT (L1), an epistemic drift + human-in-the-loop layer (L2), and ACFA Q16.16 multi-Krum + G-Set (L3) — keep heterogeneous nodes byte-identical; one prompt-injected or equivocating node can't fork, poison, or move the agreed state. Every write is signed, attributable, and exactly replayable. Architected for large swarms; bit-exact by construction.
