## Description

Compose append-only history, leases, revisioned metadata, and immutable blobs behind stable contracts.

## Where it fits

Storage is useful on its own. Use it when a Go application needs stable interfaces for append-only records, leases, revisioned key-value data, and immutable blobs without committing to a particular backend.

Within Looprig, Storage provides the persistence contracts used by [Harness](/docs/modules/harness.md), [Workflows](/docs/modules/workflows.md), [Client](/docs/modules/client.md), and [Flow Store](/docs/modules/flow-store.md). Backend modules such as [FSStore](/docs/modules/fsstore.md), [NATSStore](/docs/modules/natsstore.md), and [RcloneStore](/docs/modules/rclonestore.md) implement selected parts of those contracts. Storage defines durable operations; higher-level runtimes decide what to persist.
