The refusal landed, and the examples pin images that exist. What is
still missing is the part that makes it unnecessary: nothing in the mesh
turns a tag into a digest, so it was done by hand — which is precisely
what the issue says a person should not be asked to do.
Recorded because the resolution mechanism turned out to be trivial:
asking a registry what a tag points at takes about a second and pulls
nothing. That removes the main argument for leaving this open.
Also records the two faults that fell out of pinning for real. The mail
system named seven repositories that do not exist, because it publishes
to a different registry than the manifest assumed, and one of the seven
had been renamed upstream. Nothing checking only the shape of a
reference could have found either.
