Three faults, one mechanism each, that together let the oracle suite report
a verdict it never reached.
The address. lane_url handed out the runner's compose service name, but the
stack's containers resolve through the deployment's CoreDNS, which never
learns one: getent hosts tools answers nothing inside them, so every check
that asked the lane from there skipped itself. The bring-up now writes the
runner's address, picked as the one inside INFINITO_SUBNET because the
runner sits on every network it was ever brought up on, and the checks read
it from there. It is rewritten on both paths, because a restart gives the
runner a new one.
The readiness. serving judged the engine alone, so a lane whose engine make
i18n had already brought up counted as up while System One was down. It now
probes every role the caller names, which is why the runner republishes
System One's port: a container IP is unreachable from the host that decides
whether to deploy.
The verdict. A silent lane made the suite skip, and a skip exits green.
Only a deploy that is already running leaves the stack alone and exits 0
now; a crashed deploy and a deployed-but-silent role both exit 1.
The override's third :? guard is added to the gate that decides whether the
file is layered in at all, next to the one that was already missing. Without
it an .env written before these keys aborts every compose command, down to
compose-down, instead of dropping the lane. A test now keeps that list and
the override's guards in step.
