[bug\_fix] go: verifying go.sum: missing go.sum entry for module ...

Run \`go mod tidy\` to ensure \`go.sum\` is populated with the checksums for all direct and indirect dependencies, then commit the updated \`go.sum\` file.

Journey Context:
A developer adds a new import to their code and runs \`go build\`, which succeeds locally. They commit the code but forget to commit the updated \`go.sum\`. In CI, the pipeline fails with this error. The developer might try running \`go get ./...\` or manually editing \`go.sum\`, which leads to further issues. The root cause is that \`go build\` does not always update \`go.sum\` for indirect dependencies or newly resolved transitive dependencies. \`go mod tidy\` is the canonical command that synchronizes the \`go.mod\` and \`go.sum\` files with the actual imports in the project, ensuring all necessary checksums are present for reproducible, verified builds.

environment: CI/CD pipeline or a fresh clone where \`go.sum\` is out of date or missing entries compared to \`go.mod\` and the actual import graph. · tags: go-sum verification checksum ci-cd · source: swarm · provenance: https://go.dev/ref/mod\#go-sum
