Context

Deep-research inquiry into terminal multiplexing as agent runtime substrate, examining how distributions (Ubuntu, NixOS, Arch, Guix) and multiplexer tools (tmux, Zellij, Rmux, Upterm) enable AI agent orchestration aligned with relational software design.

Key Findings

• Cognitive externalization: pane layouts as mental models for work context
• Architecture layers: userspace vs kernel-level multiplexing; NixOS configuration-as-code enables LLM-driven env diffs
• Tools survey: Rmux (Rust SDK + daemon) most architecturally aligned; Zellij (WASM plugins); Termdock (visual monitoring)
• Low-disruption path: Rmux on Ubuntu; structural change path: NixOS (reproducible, agent-automatable)

Deliverable
