`scripts/ci-toolchain-image-resolves.sh` and `docs/ci-cd.md` both stated that the #772
container jobs "died after 1-2s", and the header used the same number to argue the preflight
needs no `needs:` gate. Nobody measured it, and it cannot be measured from a working session
without reproducing a deleted-tag incident. What the number stood for is structural and IS
known: a container job that cannot pull its image fails AT the pull, before it runs a step,
so it wastes no work waiting to be told and the argument against serialising the five jobs
survives intact.
