[synthesis] How does Cursor scale autonomous editing across large codebases without parallel agents colliding?

Isolate parallel agents with git worktrees and separate branches, and keep a live codebase index using Merkle-tree change detection so only delta chunks are re-embedded.

Journey Context:
Most AI coding tools either serialize edits or rely on a single shared context window. Cursor 2.0 combines two ideas: git worktrees give each parallel agent its own working directory and branch \(reportedly up to 8 simultaneously\), while a Merkle tree of file hashes lets the system compare root hashes to detect changed files and sync only deltas to a remote vector store. The synthesis is that scaling autonomous agents requires both write isolation and cheap incremental re-indexing; one without the other creates a correctness or latency bottleneck.
