It seems to be from this load statement. Patching that statement to include the @build_stack_rules_proto// fixes it for me locally.

I can open a PR but haven't had time to actually reproduce it outside my private repo. I don't think I'm doing anything unique so I'm not sure why this hasn't been seen elsewhere?

I have also hit this (again in a private repo) with Bazel 7.1.0. Are you using bzlmod? (I wonder if the meaning of @// changed.)

[jbedard]

Yes, this is with bzlmod.

Doesn't "@//" mean the main repo? Shouldn't this just be "//rules:proto_gazelle.bzl"?
