Know where execution ends. See where coordination begins.

Shep runs coding agents in isolated worktrees with a real CI-watch-and-fix loop and optional requirements and plan approvals before code starts. Nexus coordinates what happens once agents are actually running: ownership, verification, and approval gates active throughout the build, not just at the plan or merge stage.

Conductor isolates agent sessions in separate git worktrees. Nexus coordinates what happens across those sessions: identity, single-owner claims, verification, approval gates, memory, and an auditable record.

Emdash runs a broad range of coding agents in isolated worktrees across platforms. Nexus supplies the coordination those parallel sessions still need: ownership, verification, governance, and shared history.
