Report #49

[bug\_fix] no required module provides package github.com/foo/bar; to add it: go get github.com/foo/bar

Run go get github.com/foo/bar \(optionally pin a version with @v1.2.3\), then run go mod tidy. This adds the dependency to go.mod, downloads it, and records checksums in go.sum.

Journey Context:
An agent copies an import from documentation and runs go build. Go refuses because the package is not part of the module graph. The agent manually adds require github.com/foo/bar v1.2.3 to go.mod but forgets go.sum, so the next build fails with a missing checksum. Root cause: in module mode every import must be resolved through go.mod's require graph, and Go records checksums for every downloaded module. The toolchain command go get handles all three steps atomically.
