- Add ML-KEM-1024 + AES-256-GCM binary persistence to el_runtime.c with two-key scheme (Neuron master + user key); SHAKE-256 key derivation - Add nomic-embed-text 768-dim float32 embeddings on every node write via Ollama; graceful fallback when Ollama is not running - Wire all /api/neuron/* MCP routes directly into Engram (server.el), eliminating the Kotlin server as the MCP backend - Set ENGRAM_CHECKPOINT_INTERVAL = 1 (write binary on every node write, not every 50) - Add el_runtime.h declarations for engram_write_binary_el and engram_load_binary_el builtins
