buildctl reported: exporter "cacheonly" could not be found. Omitting --output still runs every RUN step, which is all the probe needs. Same defect exists in build-image-gitea.yml (validation path and toolchain assertion) and needs its own fix.

# TEMPORARY probe branch — not for merge.
|
|
#
|
|
# The first probe ran in the RUNNER pod. buildkitd is a different pod in a
|
|
# different namespace with its own NetworkPolicies, so those results cannot be
|
|
# transferred: an UNREACHABLE there may be the runner's policy, not routing.
|
|
# This runs the same probes THROUGH buildkitd, by building a stage whose RUN
|
|
# does the curling — that egresses from the buildkitd pod, which is the network
|
|
# position that actually has to push.
|
|
#
|
|
# It prints results and always exits 0: this is a measurement, not a gate.
