Policy set by _null. The stack pins :vX.Y.Z — never :dev, never :latest.
The reason is what a pointer cannot do. A stack file naming :dev says "dev"
today and will still say "dev" after the image underneath it changes, so the
file records a preference rather than a fact and "what is running?" has no
answer that survives the next push. Rollback is worse: there is nothing to roll
back TO, because a pointer only ever names now.
deploy.sh: with no --tag it now resolves the newest published NUMBERED version
from the registry and says which it picked, instead of defaulting to :dev. A
floating tag is refused outright, with --allow-floating as the loud escape hatch
for the one case that is not a mistake — reproducing a fault on whatever a
pointer currently is.
release.sh: no longer moves :dev. It published both tags until now because the
stack followed the pointer; under this policy nothing deploys :dev, so moving it
would only publish something that misrepresents what is running.
scripts/docker-push.sh deleted, with its npm script. Its entire job was building
and pushing an unnumbered :dev with no version bump and no guards, which is now
the exact thing the policy exists to prevent. Keeping a command that quietly
violates a policy is how the policy stops being true.
:dev and :latest stay in the registry, frozen. Not deleted: the running
container was created from :dev, and removing the tag an existing deployment
names is how a recreate fails to pull.
Stack 58 still pins :dev as this lands. Correcting that is the first deploy made
under the policy, and it is why the default resolves a version rather than
reusing whatever the stack already names.
Guards proven: default resolves v0.8.3; --tag dev refused; --tag latest refused;
--allow-floating warns and proceeds; unpublished tag still refused.
