+## Space workspace snapshot
+
+`/v1/space/workspace` returns a deterministic, read-only snapshot for the
+effective space. It aggregates the manifest, mount resolution, per-mount cursor
+status, store backend metadata, federation flags, and store capabilities into
+one JSON response. It performs no network I/O and does not mutate storage.

+This is a local snapshot that complements:
+- `/v1/space/manifest` (manifest root + canonical manifest)
+- `/v1/space/mounts/resolve` (resolved mounts + local tracking)
+- `/v1/space/sync/status` (peer-wide cursor status)
+- `/v1/space/mounts/sync/until` (active sync for track mounts)
