From a3ead6552ecf4cf4bd8e98bd86b4b634fafaf8c3 Mon Sep 17 00:00:00 2001 From: Will Anderson Date: Wed, 13 May 2026 14:43:48 -0500 Subject: [PATCH] feat(engram): ML-KEM-1024 PQC encryption, nomic embeddings, MCP routes, checkpoint-per-write - 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 --- engram/src/server.el | 490 +++++++- lang/dist/platform/elc.c | 9 + lang/el-compiler/runtime/el_runtime.c | 228 ++++ lang/elb.el | 2 +- lang/releases/v1.0.0-20260501/el_runtime.c | 1198 +++++++++++++++++++- lang/releases/v1.0.0-20260501/el_runtime.h | 5 + 6 files changed, 1862 insertions(+), 70 deletions(-) diff --git a/engram/src/server.el b/engram/src/server.el index ebaf34a..ec11720 100644 --- a/engram/src/server.el +++ b/engram/src/server.el @@ -6,9 +6,17 @@ // database. // // Built and linked with: -// elc src/server.el > server.c -// cc -std=c11 -O2 -lcurl -lpthread -o engram server.c el_runtime.c -// ./engram +// elc src/server.el > ../dist/engram.c +// cc -std=c11 -O2 \ +// -I/Users/will/Development/neuron-technologies/foundation/el/lang/releases/v1.0.0-20260501 \ +// -I/opt/homebrew/Cellar/liboqs/0.15.0/include \ +// -I/opt/homebrew/opt/openssl@3/include \ +// -L/opt/homebrew/Cellar/liboqs/0.15.0/lib \ +// -L/opt/homebrew/opt/openssl@3/lib \ +// -lcurl -lpthread -loqs -lssl -lcrypto \ +// -o ../dist/engram ../dist/engram.c \ +// /Users/will/Development/neuron-technologies/foundation/el/lang/releases/v1.0.0-20260501/el_runtime.c +// ./dist/engram // // Configuration via environment: // ENGRAM_BIND — host:port (default :8742) @@ -83,7 +91,61 @@ fn route_create_node(method: String, path: String, body: String) -> String { let salience: Float = json_get_float(body, "salience") if salience == 0.0 { let salience = 0.5 } let id: String = engram_node(content, node_type, salience) - "{\"id\":\"" + id + "\",\"content\":\"" + content + "\",\"node_type\":\"" + node_type + "\"}" + + // Auto-link: find semantically related existing nodes and form edges. + // The search engine is substring-based: engram_search_json(query, limit) + // returns nodes whose content/label/tags contain `query` as a substring. + // Strategy: try the first word of content; if it is too short (< 5 chars), + // fall back to the second word.
