git-worktree - Manage multiple working trees
Developer CLI Tool
Summary
Lane is a Rust CLI that creates copy-on-write Git worktrees via filesystem reflinks, preserving ignored build caches across checkouts. It also attaches durable notes to files or symbols and flags them when the anchored code changes. No AI model calls.
Highlights
- Uses clonefile(2) on APFS and FICLONE on btrfs/XFS to clone ignored caches by reference, allocating storage only for changed blocks
- Attaches durable Markdown notes to files or symbols and flags them when the anchored code changes
- Never calls a model; all functionality is local and deterministic
- Prebuilt binaries for macOS and Linux (arm64/x86_64); falls back to normal worktree when reflinks unavailable
- Shell integration for zsh, bash, and fish with automatic cd into/out of lanes and tab completion

Source Overview
Lane is a Rust CLI that creates copy-on-write Git worktrees via reflinks so ignored build caches persist across checkouts.
It stores Markdown notes anchored to files or symbols and flags them when the anchored code changes. Prebuilt binaries ship for macOS and Linux; Lane never calls a model.
