# Jobs run in container images so a runner needs only docker or podman, not a Go toolchain.
# GOFLAGS=-buildvcs=false: the checkout is owned by the runner's user, not the container's,
# so git refuses it and Go's VCS stamping fails the build.
#
# Caches (HAL-3505): a job's `cache:` directories are kept between jobs, mounted at
# /work/<dir> from a volume per repository, directory and image. Go is pointed at them, so a
# job reuses the modules and compiled packages the last one left instead of downloading and
# compiling everything again (vet and build each took ~97 s from nothing, 2026-10-17). They
# live under .cache/, which `./...` skips as a dot-directory. fmt stays uncached: `gofmt -l .`
# would walk the module cache, and it takes a second anyway.
#
# Paths (HAL-3505): Lorx's step cache keys each step on the whole checkout, so any change, a
# README included, re-runs every step; `paths` decides whether a job runs at all. The Go jobs
# run when Go code, a module file, or anything Go reads changes: the embedded migrations under
# pkg/, the testdata, the lint config and this file. A change to docs/, charts/, selfhost/ or
# the READMEs runs none of them.
