Three unbounded remote-filesystem paths, all reachable by browsing or downloading a large directory over SSH. Directory listing - `readDir` now calls the relay's bounded `fs.readDirBounded` and validates the response against the same ceilings it asked for, so a relay that ignores the limits cannot hand back an arbitrarily large listing. - An older relay without the bounded method is refused with a reconnect prompt rather than falling back, since the fallback is exactly the unbounded enumeration this removes. SFTP enumeration - `readDirViaSftp` materialized an entire directory before returning. `readDirectoryEntriesViaSftp` is an async generator over `opendir`/`readdir` chunks, so a caller that stops early -- at a budget ceiling, or on cancel -- never holds the whole listing. The handle is closed on every exit path. Folder transfer budget - `SshDirectoryTransferBudget` bounds entries, depth, per-path bytes, retained path bytes, per-file bytes, and total file bytes for recursive transfers. - Upload and download get separate limit sets. Uploads build an in-memory package, so 4,096 entries / 32 MiB total is right. Downloads stream each file to disk and hold one directory's entries at a time, so that ceiling would reject an ordinary checkout containing node_modules; downloads get a 1,000,000-entry whole-tree backstop while keeping the depth and per-path guards. Every bound is mutation-tested -- removing any one of the nine fails at least one test, including the download/upload limit-set choice and the streaming generator itself.

Features
Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
