Knowledge Layer

The Knowledge Layer is RoRo Studio’s organizational memory system. It stores decisions, runbooks, standards, and architecture documentation in a Git-backed Obsidian vault, indexed into PostgreSQL for agent retrieval via MCP.

Architecture

• Storage: Git monorepo (RoRoStudio/knowledge-base)
• Human interface: Obsidian (desktop + Android)
• Publishing: Quartz v4 at knowledge.rorostudio.com
• Retrieval: PostgreSQL FTS + pgvector hybrid search
• MCP server: FastMCP at mcp.rorostudio.com/knowledge/mcp
• Automation: n8n workflows for indexing, issue-to-knowledge pipeline, freshness audit

Key decisions

• ADR-0001: Use Git-backed knowledge base

Linear issues

• ENG-31: Create repository
• ENG-32: Create database
• ENG-33: Build MCP server
• ENG-34: Indexing workflow
• ENG-35: Issue-to-knowledge pipeline
