1//! OCI image pulling, EROFS materialization, and caching for microsandbox.
2//!
3//! This crate implements the OCI image lifecycle:
4//! - Registry communication (pull, auth, platform resolution)
5//! - Layer caching with content-addressable dedup
6//! - Tar ingestion into in-memory file trees
7//! - EROFS filesystem image generation (per-layer and flat modes)
8//! - ext4 upper disk formatting for writable overlay upper layer
9//! - Minimal EROFS reader for Append patches

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