Five findings from the review of the previous commit, all confirmed against the source before acting. The untracked list escaped every bound the previous commit added. `git ls-files --others` reports the whole tree of anything not yet ignored, so a fresh clone before `node_modules` / `target` / `.venv` reach `.gitignore` answers with tens of thousands of paths — read through the buffering helper, retained without a cap, ignored by `oversized()`, and rendered one non-virtualized row each. That reaches the overlay without going through the diff at all, which is why the diff budget never saw it. It is now streamed through `git_lines`, capped at `MAX_UNTRACKED`, counted toward the oversized threshold, and rendered at most `MAX_RENDERED_FILES` rows with a "… and N more" tail. The reported count stays the true total via `untracked_total` — same split the diff side already makes between what is retained and what is counted, because a count that shrank with the budget would read as files having disappeared. The overlay's expand state was an inversion set — "files flipped away from their default" — which was correct while the default was per-file and stable. The repo-wide `collapse_all` moves the default for every file at once, so any refresh crossing the oversized threshold inverted every explicit choice simultaneously: the two files the user had opened snapped shut and the rest sprang open. It now stores absolute intent (`HashMap<String, bool>`), answered before the default is even computed, so nothing about the snapshot can reach it. Covered by a test that asserts an explicitly opened and an explicitly closed file both survive a transition in either direction while an untouched file follows the default. The Changes panel dropped freshly landed snapshots. `install_diff_snapshot` only wrote `right_panel.diff` when the panel was the one waiting, so a probe the overlay started was discarded even when the panel sat on that exact repo — the overlay rendered the new snapshot while the panel kept the old one, same window, same repo. The wait (`diff_pending`) and the data (`diff_cwd`) are now claimed separately: with probes deduped per cwd there is at most one in flight, so there is no out-of-order overwrite to guard against. The oversized banner reported `retained_lines()` as "diff lines", which after the budget fires is what was kept, not what changed — it read "20000 diff lines" directly under a header showing the exact +90000/-0. It now states loaded-of-total and names which cap ate the difference, and lists each axis that tripped the threshold so a big untracked list never reads as a claim that the diff is big. And the Changes panel deep-copied every untracked path String on every frame, on the UI thread, for two `len()`/`is_empty()` reads — the same cost class the `Arc` switch removed from the probe path. 995 tests pass, fmt clean, no new clippy warnings. The app was not built, launched, or driven; visual acceptance is the owner's. Refs #239.

Why
- Fast — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
- Sessions persist — quit or reboot; your shells keep running, no tmux
- Editor-grade input — completion, syntax highlighting, history search built in; zero config for zsh, bash, fish, PowerShell
- Agent-aware — recognizes Claude Code & co. in a pane: status, notifications, session resume
