Infrastructure Decisions — March 2026

Always-On Agent (Mac Mini)

• Claude Code with channels (Discord + iMessage)
• tmux for session persistence
• LaunchAgent for boot startup + daily 4am restart with updates
• Permission mode: acceptEdits with broad allow list
• Full Disk Access granted to tmux for iMessage chat.db access

Knowledge Management

• Obsidian as vault UI/editor (auto-launches on boot)
• QMD as local search engine (hybrid BM25 + vector + LLM re-ranking)
• QMD configured as MCP server via ~/.mcp.json
• QMD runs on node (not bun) due to sqlite-vec extension incompatibility

Connected Services (MCP)

• Gmail (ben@raydata.co)
• Google Calendar
• Notion
• Slack
• Discord (channel plugin)
• iMessage (channel plugin)

Evaluated and Deferred

• Notion as primary memory: deferred in favor of local-first Obsidian + QMD
• Basecamp: too much for current stage, revisit if team grows
• RAG database: QMD provides 80% of the benefit without infrastructure overhead
• 1Password CLI: identified as best option for agent credential management, not yet set up
• Supply chain risk: with this many dependencies, package integrity matters — see Supply Chain Security SOP for how we manage it
