| Composes with | unlimited distinct namespaces x 250 MB each — the namespace is free and unauthenticated, so it multiplies like a bucket-per-name. 500 GB would need 2,000 namespaces and 111,000 files at the 4.5 MB cap. |

| Reliability | Tiny per-file cap (4.5 MB) means the multiplier is the namespace count, not file size; namespace squatting is first-come and unauthenticated. New/small operator. |
