- Pairing saves nothing if it was cancelled while adding the key. - The ssh stand-in runs under bash: dash refuses job control without a terminal, which cost stdin and the process group. - A server that stops while the tunnel opens fails the attempt (and retries) instead of leaving it half-connected. - The health probe answers within its deadline even when a dead link keeps the probe itself waiting. - A cached version is deleted only if no server runs from it (servers now run by absolute path) and it's two weeks unused.

# `ssh [options] frame COMMAND`, and rsync calls it as its transport; here that
