`an_install_reports_both_transfers_to_completion` and
`every_report_carries_the_host` built their `Installer` by hand — `with_version`
and `with_timeouts`, no `with_dialect`. So they ran at
`RemoteProtocol::of_this_build()` while `FakeRemote` answered the `--protocol`
probe with the fixture's fixed `c3p4`, and passed only because the real
`CONTROL_VERSION` currently *is* 3.
Found by bumping `CONTROL_VERSION` to 4 locally: both tests fail with
`DialectMismatch { wanted: c4p4, spoke: c3p4 }` — an error about a fake's
plumbing, raised in two tests that are about *progress reporting*, at the one
moment somebody is busy changing the wire and least able to spare the
attention. The fixture's own comment says the dialect is a fixed literal
"rather than `RemoteProtocol::of_this_build`", which is exactly right and was
exactly what these two bypassed.
Both now go through `installer()`, whose `release` parameter is a
`&dyn AssetFetcher` so that a chunked fetcher — the only reason either test
hand-rolled the builder — is no longer a reason to leave the helper. The
helper's doc says what forgetting it costs, since that is the failure mode a
reader needs and the compiler cannot give.
No behaviour change, and the same 644 tests before and after.

tty7
A terminal workbench: shells, sessions, SSH, coding agents.
Pure Rust · GPU rendering on Zed's gpui · VT core from Alacritty
English · 简体中文
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
