Report #15028

[bug\_fix] module declares its path as: X, but was required as: Y

Update the \`module\` directive in the dependency's \`go.mod\` file to match the repository URL it is fetched from, or change the import path in the consuming code. If using a fork, add a \`replace\` directive in the root \`go.mod\` to map the original module path to the fork's URL.

Journey Context:
A developer forks a GitHub repository to fix a bug, pushes it to their personal GitHub namespace, and updates their project's \`go.mod\` to require the fork via \`require github.com/their-user/repo v1.0.0\`. The build fails with a path mismatch error. They investigate the fork's \`go.mod\` and realize the \`module\` directive still says \`module github.com/original-user/repo\`. Go uses the \`module\` directive, not the fetch URL, for package identity. They fix it by adding \`replace github.com/original-user/repo => github.com/their-user/repo v1.0.0\` to their root \`go.mod\`, which correctly maps the original identity to the forked source.
