Research direction
Start with the linked GitHub Actions run and inspect the buildx invocation, builder configuration, and complete logs around “invalid user index: -1.” Compare the environment and BuildKit/buildx versions used there. Done means identifying a reproducible cause and documenting or fixing it with a regression test, if the repository has a matching test entry point.
