// includes the jurisdiction so entries whose index row carries no cell don't

### TestGroupReposByCell_Placements

This test verifies the grouping of repos with placements into their own cell group.

```go
func TestGroupReposByCell_Placements(t *testing.T) {
    t.Parallel()
    repos := []coreapi.RepoIndexEntry{
        {
            ID: "01US", Cell: "aws-us-east-2", ClusterSlug: "us-prod", Jurisdiction: "us",
            Placements: []coreapi.RepoPlacement{
                {ID: "01US", Cell: "aws-us-east-2", Jurisdiction: "us"},
                {ID: "01EU", Cell: "aws-eu-central-1", Jurisdiction: "eu", Mirror: true},
            },
        },
        {
            ID: "01LEGACY", Cell: "aws-us-east-2", ClusterSlug: "us-prod", Jurisdiction: "us",
        },
    }
    cells := groupReposByCell(repos)
    if len(cells) != 2 {
        t.Fatalf("groups = %d, want 2 (one per cell): %+v", len(cells), cells)
    }
}
```

### TestResolveCellBaseURLs_RefusesBaseURLWithoutJurisdiction

This test verifies that a concrete baseURL is only usable together with its jurisdiction.

```go
func TestResolveCellBaseURLs_RefusesBaseURLWithoutJurisdiction(t *testing.T) {
    t.Parallel()
    cells := []cellGroup{{cell: "aws-us-east-2", clusterSlug: "us-prod", jurisdiction: "us"}}
    // ...
}
```
