# Repository checks: the script checks every change runs, in one job.
#
# Each of these is a script that reads the tree for a few seconds. They were six
# workflows and nine jobs (lockfiles, tests-in-ci, workflow-hygiene, wai-section-refs,
# spec-refs and no-vanity-metrics' four), and each job paid for a container and a
# checkout to run them. On 2026-10-14 the light checks were about half of the 119 jobs
# waiting for the linux-arm64 runner, queued behind the long standards-build legs, and
# spec-refs held a place on the one x86_64 runner. One job runs them all now, one step
# a check: every step runs even after an earlier one fails (`!cancelled()`), so a red
# job names each failing check in its own step, and the job fails if any did.
#
# The two path filters the old workflows had (public text on Markdown and wai/ sources,
# section references on the WAI documents) are gone: the checks take seconds, and a
# filter that is wrong skips a check silently.
