//! OCI image pulling, EROFS materialization, and caching for microsandbox.
//!
//! This crate implements the OCI image lifecycle:
//! - Registry communication (pull, auth, platform resolution)
//! - Layer caching with content-addressable dedup
//! - Tar ingestion into in-memory file trees
//! - EROFS filesystem image generation (per-layer and flat modes)
//! - ext4 upper disk formatting for writable overlay upper layer
//! - Minimal EROFS reader for Append patches

// New lints introduced in rustc 1.95 fire on existing code; cleanup
// tracked separately.
