Crux

Local-first memory, retrieval, and receipts daemon — one binary, MCP + HTTP + CLI

The Crux daemon (corecruxd) is the CueCrux memory system: local-first fact storage, hybrid retrieval, CROWN receipts, session handshake, and cross-session coordination in a single Rust binary (HTTP :14800, MCP :14801). Supersedes the separate VaultCrux (hosted API) and MemoryCrux (MCP adapter) products — both surfaces are now served by the daemon.
