Architecture

See the diagram on VNX-DNA. Packages are layered: core (schemas, errors), container/archive, dnaenc/codec, ecc, simulation/providers, recovery, pipeline, sdk, commands, secure. Formats are versioned on separate axes (container, strand frame, superblock) and V4/V5 archives keep decoding. Source: docs/ARCHITECTURE.md, specification docs/spec/VNX-DNA-SPEC-V6.md.
