l0ng-aiandl0ng-ai f2fe829cb6 fix(sftp,forwards,files): tell a failure apart from an empty result (#518)
* fix(sftp): stop a failed poll from reading as an empty transfer list

A transfer poll that could not reach the daemon answered with an empty
`Vec`, which is indistinguishable from "every transfer is gone": the tray
disappeared and every upload the panel was waiting on counted as landed,
so a spurious "the upload finished" refresh fired. Over a link that is
down that is the permanent answer, not a blink.

`SftpRoute::transfer_list` and `RemoteTerminal::sftp_transfer_list` now
report the failure the way `sftp_list` already does. A failed poll keeps
the jobs the panel last saw, settles nothing, and says so in the transfer
tray through a new `jobs_error` — kept apart from `SftpPanelState::error`,
which blanks the directory listing a poll knows nothing about.

* fix(forwards): let a forward whose loop has exited say so

`ForwardEntry.status` was written once when the forward was set up and
never touched again, so a local or dynamic forward went on reporting
`Listening` after its accept loop had already exited. The pane outlives a
dead SSH transport on purpose, the daemon keeps it while a subscriber is
attached, and the panel re-polls every 2s — so the stale `Listening` is
not a blink but the permanent answer. `nc` to the port gets accepted once
and refused thereafter while the panel still shows it as live.

The status is now an `Arc<Mutex<ForwardStatus>>` shared with the task, and
both break arms record why they left: the listening socket closed, or the
SSH connection went away. `ForwardStatus::Error` carries it rather than a
new variant, because the enum crosses the protocol to `tty7-server` builds
that would not know one. `find_auto_local` reads the live status too, so a
loopback link is no longer reused after its forward has stopped serving.

A remote forward has no accept loop of its own — the far end opens the
channels — so it keeps whatever the `tcpip-forward` request answered.

* fix(files): tell a failed search from an empty one, and name the file a write failed on

Two ways the file tree answered a failure with something that reads as a
result.

A search was `unwrap_or_default()`ed inside the worker, so a host that
refused the walk left `hits` empty and the column printed "Nothing matches
{query}" — byte-identical to a genuine zero-hit search. The worker now
reports `(ok, hits)` the way `spawn_load` already reports a listing, and a
failed walk draws a `SearchFailed` note in the danger colour, the same
distinction `FileTreeState.unreadable` draws for a directory.

Creating and renaming pushed the bare `io::Error`, so the toast was
literally "Permission denied (os error 13)" — neither which file nor what
was being done to it. Both now go through `HostOps::notify_err` like
delete and drop-copy already do, naming the file; a rename names the name
it is leaving, which is the one still on screen.

tty7 with a tab sidebar of agent sessions across several repos, running Claude Code

Why

  • Performance — ~2× the throughput of Alacritty, Ghostty, or Kitty (benchmarks)
  • Persistent sessions — quit or reboot; your shells and supported agent sessions keep running, no tmux
  • Editor-grade input — suggestions, completion, highlighting, history search
  • Remote development — files, repos, panes, and git data stay on the remote machine
  • Native SSH — profiles, SFTP, port forwarding, and jump hosts
  • Agent-aware — Claude Code, Codex & co.: status, notifications, git context
  • CLI + Skills — agents create panes, run commands, and inspect output

Install

Native builds for each platform on Releases:

macOS …-macos-arm64.dmg · …-x86_64.dmg drag into Applications
Windows …-setup.exe · portable ….zip
Linux …-x86_64.AppImage chmod +x and run — X11/Wayland libraries bundled

What's inside

Editor-grade input ghost suggestions from history · explained tab completion · syntax highlighting · multi-line editing · click places the caret · ⌃ R fuzzy history
Window tabs & splits · ⌘ P palette · ⌘ F scrollback search · nine themes · IME
Agent-aware per-pane detection (18 CLIs): status dot · notifications · branch + diff · resume after reboot · tray icon when input is needed
Remote workspaces remote files, repos, changes, diffs, worktrees, tabs, and panes · reconnect from any client and continue where you left off
CLI + Skills bundled tty7 CLI · agent skill · pane/workspace control · real PTY commands · output, process, port, and agent status
SSH native russh stack: profiles with keychain secrets · SFTP panel · port forwarding · jump hosts · one-time, unprivileged tty7-server install

Full documentation lives in docs/keyboard shortcuts · config.json · CLI reference. The agent-facing CLI interface is also documented in skills/tty7/SKILL.md.
