# STORAGE_ROOT_MISMATCH

**Computed root doesn't match expected**

## What happened

Two computed Merkle roots disagree — typically the local recomputation after download doesn't match the on-chain root, indicating tampering or a different chunking scheme.

## How to fix

Re-download with the canonical chunk size (256 KiB) and recompute. If still mismatched, the upload may have been corrupted — re-upload from source bytes.

## Example

```ts
import { Storage } from "@foundryprotocol/0gkit-storage";
const local = await Storage.computeRoot(bytes);
```
