I'm not sure if this makes sense as a function of a MiloBuild; I suspect that
we'll want to generate and update BuildSummaries with only partial information
directly from the backends without loading the whole native build and converting
it to a MiloBuild first, right?

Yeah, this is meant to fill in extra information if the full build is available.
 That's why it fills in a buildSummary instead of returning one.

+	bs.Summary = rb.Summary.toModelSummary()
+	if rb.Summary.Status == model.Running {
+		// Assume the last step is the current step.
+		if len(rb.Components) > 0 {
+			cs := rb.Components[len(rb.Components)-1]
+			bs.CurrentStep = cs.toModelSummary()
+		}
+	}
+	if rb.SourceStamp != nil {
+		// TODO(hinoka): This should be full manifests, but lets just use single
+		// revisions for now.
+		if rb.SourceStamp.Revision != nil {
+			bs.Manifests = append(bs.Manifests, model.ManifestLink{
+				Name: "REVISION",
+				ID:   []byte(rb.SourceStamp.Revision.Label),
+			})
+		}
+		if rb.SourceStamp.Changelist != nil {
+			bs.Patches = append(bs.Patches, model.PatchInfo{
+				Link:        rb.SourceStamp.Changelist.Link,
+				AuthorEmail: rb.SourceStamp.AuthorEmail,
+			})
+		}
+	}
