The main-process worktree resolution cache expired on wall-clock time: the whole-fleet snapshot has a 1s TTL, so any poller faster than 1Hz recomputed it, and every 30s the per-repo scan cache expired and shelled out `git worktree list` for every registered repo. A production trace recorded 4,272 `git worktree` invocations over 3h27m across 10 repos. In-Orca mutations are already event-driven, so the 30s TTL existed only to discover changes made outside Orca. Before re-running an expired scan for a local, non-WSL repo, read a cheap subprocess-free Git-admin fingerprint (admin dir entries, per-checkout HEAD and its ref tip, gitdir/locked/existence per entry, packed-refs and reftable stamps). If it matches the fingerprint captured at the cached scan's start, extend the cache without spawning Git. A real scan still runs every 5 minutes so anything the probe cannot see still reconciles. Measured: 600 -> 60 `git worktree list` spawns on the reported workload (10 idle repos, 1Hz polling, 30 simulated minutes), and main-thread event-loop stall of 2.69ms -> 0.01ms per refresh. External worktree add/remove/move/lock/checkout/commit discovery stays bounded at 30s. SSH repos, WSL-routed repos, folder workspaces, agent-scratch repos, and any repo whose layout the probe cannot read keep today's behaviour exactly.

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.
