The pre-push gate ran the self-hosted claw relay (ssh + Lima Debian) as a
hard stage, so any time the host was unreachable the whole hook failed and
the only way past it was a blanket --no-verify, which also discarded the
local macOS Swift gate. The authoritative Linux gate is the GitHub-hosted
workflow (ubuntu-latest + swift:6.2); the relay is a convenience fallback.
check-linux.sh now separates connectivity and provisioning (Stage A, exit 77
to signal skip when the relay is unavailable) from the relayed build and test
(Stage B, exit 1 on a genuine Linux failure). check-all.sh treats 77 as a
non-fatal skip and still aborts on any other non-zero, so a runner outage no
longer blocks a green push and never masks a real failure.
