//! `meta-feeder-sdk` — the source-agnostic foundation shared by the gateway
//! core and every feeder sidecar binary.
//!
//! A *feeder* implements [`FeederPlugin`] (find records, fetch bytes) for one
//! or more upstreams, and [`serve_feeders`] exposes them over the feeder HTTP
//! contract. The gateway core consumes that contract via its
//! `RemoteFeederPlugin` and keeps the libp2p wire, the bitswap blockstore, the
//! hashing-into-the-blockstore, and the meta-core store-back to itself.
//!
//! Deliberately libp2p-free and blockstore-free — see this crate's `Cargo.toml`.

// `redb::Error` is a large enum; the cache wrappers (`cache.rs`) return it
// directly rather than boxing on every embedded-DB call. Boxing each would be
// pure noise for a single-process store, so silence the lint crate-wide.

/// the modular storage seam out of compose: a standard install just works; a
/// non-standard meta-core is set in the feeder's config UI. Matches the
/// `metacore-app` service the AppStore feeder apps ship on the shared network.
