Highlights

• Argon2id password hashing (upgraded from SHA-256)
• Login brute-force protection (5 failures = 15min lockout)
• Constant-time admin key comparison
• Guard honeypot ports configurable via environment variables
• SDK classes rebranded: EpicodeClient, EpicodeAdmin, EpicodeError
• CI workflow with Rust check + Node build
• Contributing guide, security policy, issue/PR templates

Epicode — AI Memory Operating System

Description

Epicode is an open-source spatial AI memory system that gives AI agents persistent, searchable, and interconnected memory across sessions.

Core capabilities:

• Vector Memory Storage — Every piece of information is embedded, indexed, and retrievable across sessions
• Semantic Search — BM25 + HNSW hybrid retrieval; natural language queries return contextually relevant results with similarity scores
• Knowledge Graph — Automatic relation extraction creates a dynamic graph of interconnected memories for deep recall and contextual understanding
• 33 MCP Tools — Full suite for memory CRUD, context management, pattern learning, skill execution, identity confirmation, and more
• Spatial Tetrahedra Encoding — Memories encoded as regular tetrahedra in continuous 3D space; shared vertices naturally form clusters
• Dream Consolidation — Automatic memory strengthening and cleanup cycle, inspired by human sleep
• Multi-user Cloud — User registration, API key auth, quota management, sub-accounts
