origin vs ctx-open

origin: Origin provides a local memory and knowledge system for AI workflows, enabling agents to recall past context, capture decisions and lessons, and distill them into versioned wiki pages. It uses hybrid retrieval (vector + FTS + graph) and git versioning for auditable, refreshable context.; ctx-open: CTX is a cognitive version control system for AI agents, preserving structured reasoning artifacts as durable state instead of ephemeral chat transcripts. It enables agents to maintain continuity across sessions, track decisions, and reproduce reasoning paths. The system includes a CLI, a local MCP server, and a web viewer.
