| Interface | s3-compatible HTTP gateway (:3000) for upload/download; S3-compatible product separately; miner/validator P2P via iroh FetchBlob. |

| Tooling | Reed-Solomon k=10/m=20 over 2 MiB stripes, CRUSH placement, PoSt audits via Plonky3, on-chain miner registration. |

| Composes with | Interesting architecture reference rather than a usable free store: it is the only system seen that combines erasure coding with iroh, i.e. 20 TiB of user data would occupy 60 TiB of miner disk at 3x parity. |
|---|
| Reliability | Testnet-stage code; the validator is a metadata authority and a single point of coordination for placement and recovery. |
