Report #104339

[bug\_fix] verification failure: checksum mismatch \(go.sum is missing or corrupted\)

Delete the existing go.sum file and run \`go mod tidy\` \(or \`go mod download\`\) to regenerate it from the go.mod file and module cache.

Journey Context:
A developer manually edits go.mod to add a dependency without running \`go mod tidy\`, or uses a different Go module proxy that produces different checksums. The next \`go build\` fails with a checksum mismatch. After some confusion, the developer deletes go.sum, runs \`go mod tidy\`, and the build proceeds normally.

environment: Go 1.11\+, any operating system, any Go module proxy setting. · tags: go.sum checksum verification tidy · source: swarm · provenance: https://go.dev/ref/mod\#go-sum-files
