/**
 * Baseline: the current `WorkspaceFileSystem` must satisfy the shared
 * FileSystem + git-on-FS contract. When `ArtifactsFileSystem` lands, a sibling
 * test file runs the same `fileSystemContractCases`/`gitOnFsCases` against it,
 * proving the swap is a behavioral drop-in.
 *
 * A real `SqlStorage` is obtained from an empty harness Durable Object
 * (`FsHarnessDO`) via `runInDurableObject`; each case gets a fresh DO instance
 * (unique id) so storage is isolated.
