Implements FSRS-6 spaced repetition with power-law forgetting and hybrid 4-channel search (vector embeddings, full-text, personality signals, knowledge graph traversal) powered by libsql with local ONNX embeddings. Includes personality extraction from conversations, fact validation with temporal windows, contradiction detection, and audit trails—all with multi-tenant isolation and optional LLM integration for any OpenAI-compatible provider. Bundles seven orchestration microservices (agent registry, task tracking, event bus, workflows, evaluation, logging, analysis) as native modules sharing a single database.
