Report #101477

[bug\_fix] cannot find module providing package github.com/org/lib: module github.com/org/lib@latest found \(v1.2.3\), but does not contain package github.com/org/lib

Update the \`module\` directive in go.mod to match the repository's canonical import path \(including any subpath\), or move the module root so the directory layout aligns with the declared module path. Then run \`go mod tidy\` and rebuild.

Journey Context:
A team forks an internal library from \`github.com/oldteam/utils\` to \`github.com/newteam/utils\`, changes imports in consuming services, but forgets to update the \`module\` line inside the forked repo's go.mod. \`go build\` downloads the latest tag successfully from the new remote, but Go's package loader compares the import path \`github.com/newteam/utils\` against the module's self-declared identity \`github.com/oldteam/utils\` and rejects it because the module path in go.mod is authoritative. The developer first blames the proxy cache, clears \`~/go/pkg/mod/cache\`, and even re-tags the repo, but the error persists because the metadata inside the module is wrong, not the remote state. Once go.mod is corrected and \`go mod tidy\` refreshes go.sum, imports resolve normally.

environment: Go 1.21\+, modules enabled, consuming service imports forked library via module proxy · tags: go modules module path mismatch import fork go.mod · source: swarm · provenance: https://go.dev/ref/mod\#go-mod-file-module
