Report #97207

[bug\_fix] go: module declares its path as: github.com/old-org/bar, but was required as: github.com/new-org/bar \(module path mismatch\)

Update the module directive in the dependency's go.mod so it matches the canonical import path consumers use, or update the consumer's imports/require/replace directives to match the declared path, then run go mod tidy. If the repo moved, change the 'module' line, not just import statements.

Journey Context:
We moved a library from github.com/old-org/bar to github.com/new-org/bar and updated all import paths in the main repo, but local builds still worked because a replace directive pointed at the checked-out directory. In CI, with no replace and a fresh module cache, go build failed with a module path mismatch. The error message pointed at the dependency's go.mod, which still said 'module github.com/old-org/bar'. After tracing with 'go list -m all', we realized Go identifies a module by the path declared in its go.mod, not by the URL it was fetched from. Updating the dependency's module directive to github.com/new-org/bar and bumping the required version made the mismatch disappear.

environment: Go 1.21 module-aware mode, public module proxy \(proxy.golang.org\), CI runner without local replace overrides · tags: go modules module path mismatch go.mod replace import canonical · source: swarm · provenance: https://go.dev/ref/mod\#modules-overview
