Function TestPublishedManifestMatchesAssetName

internal/update/drift_test.go:109–150

TestPublishedManifestMatchesAssetName is opt-in: point CODEHAMR_CHECK_MANIFEST at a goreleaser checksums file (CI sets it to dist/codehamr_checksums.txt after a release build) and it asserts the published asset names are EXACTLY the set assetName produces. This is the only check that exercises real

(t *testing.T)

// of which the hermetic test above can see. Skips when the env var is unset, so
// the default `go test ./...` never needs goreleaser or the network.
