[bug\_fix] go: verifying go.sum: missing go.sum entry for module github.com/some/[email protected]

Run go mod tidy to automatically add missing entries and remove unused ones, or go get github.com/some/[email protected] to explicitly fetch and record the checksum.

Journey Context:
A developer pulls the latest code from version control and tries to build. The build fails with 'missing go.sum entry'. They notice that a colleague added a new import but forgot to commit the updated go.sum file. The developer tries to just build again, but Go strictly verifies checksums for reproducibility. They try manually editing go.sum, which leads to checksum mismatches. Finally, they run go mod tidy, which calculates the correct cryptographic hashes for the new dependency, updates go.sum, and allows the build to proceed securely without compromising supply chain verification.

environment: Go 1.16\+, CI/CD pipelines or team environments · tags: go-sum checksum mod-tidy dependencies · source: swarm · provenance: https://go.dev/ref/mod\#go-sum
