Dev only. This package is a local development fixture — it accepts any S3 credentials, carries no auth or metrics. It is not meant for production; production dapp backends publish to real object storage (S3/R2).

Serves a dapp backend's layout from a single origin using subfolders (/state, /data, /index) — the S3-compatible storage half of the aries dapp local backend. The subfolders are S3 buckets on an embedded S3-compatible server (s3rver), so any S3 client writes into them unchanged while readers (browser dapps, curl) fetch the same layout paths over plain HTTP or optional TLS.

The three buckets:

data — immutable, append-only facts (the source of truth).
state — mutable current derived view, rebuilt on an interval by the DappActor.
index — query-optimized derived views, rebuilt on an interval by the DappActor.

This package is the storage layer only. The DappActor that derives state and index from data, and the composed daemon that runs both the server and the actor, live in @ariestools/aries-dapp-core. aries dapp up spawns that composed daemon.

Kind	Behavior
`memory`	Ephemeral temp directory, wiped on `close()` / process shutdown
`disk`	Caller-owned directory (e.g. `~/.aries/dapp/data`); survives restarts; `cleanup()` is a no-op
