 ## Startup and streams
 
 - Startup waits until the app's tailnet node lists the server's node among its peers, not just until it is `Running`: a node starting from libtailscale's netmap cache reports `Running` with no peers before control sends the real netmap, and a dial then waits out the SOCKS proxy's 5 s and is refused, which `URLSession` reports as "bad URL".
-- `AsyncBytes.lines` drops blank lines, including the ones that end SSE events.
 - Run byre on this Mac and the Server tab run `byre install` through the user's login shell, since `byre install` copies its `PATH` into the service and the app's own `PATH` from launchd finds none of `claude`, `codex`, `agy` or `npx`.
 - SwiftUI's window restoration is off, but the scene keeps the id `main` that earlier builds used: AppKit restores their saved window by that id, and SwiftUI then opens no launch window at all when the id names no scene.
 - The app logs through `os.Logger`: `log show --last 10m --predicate 'subsystem == "run.fc.byre.mac"'` prints it.

 - `git fetch` and `git push` run non-interactively (`GIT_TERMINAL_PROMPT=0`, ssh `BatchMode=yes`, overriding any `core.sshCommand`), so a remote needing a password or an unknown host key fails at once instead of waiting for input. Every git command runs in its own process group, killed whole on timeout, so an `ssh` it started can't finish a fetch or push after byre has moved on.
 - A push error other than a non-fast-forward rejection is ambiguous, since the remote may have taken the push before the connection dropped; byre then fetches and checks whether the commit landed before deciding.
 - The project's checkout must have the default branch checked out: a merge fast-forwards it.
-- byre's `grep` doesn't read the global `core.excludesFile`.
