Report #97683

[bug\_fix] verification of go.sum failed: compute hash of module content differs from recorded hash in go.sum

Delete the corrupted go.sum file and regenerate it with \`go mod tidy\` \(or \`go mod download\`\). Ensure network access is present and the module proxy \(e.g., proxy.golang.org\) is reachable.

Journey Context:
During a CI build in a Docker container, \`go build\` failed with a go.sum verification error. The team had previously committed a go.sum file that was accidentally edited manually or corrupted by a shallow git clone. The developer added \`rm go.sum && go mod tidy\` to the Dockerfile. After re-running, the build succeeded. The root cause was that the sum file had a stale hash for a transitive dependency that had been updated without regenerating sums.

environment: Go 1.20, Docker-based CI on GitLab, module proxy set to default · tags: go.sum verification error ci build corruption · source: swarm · provenance: https://go.dev/ref/mod\#go-sum-files \(Go Modules Reference - go.sum files\)
