Modules

bytes

Little-endian field readers that return a typed error instead of panicking. Every on-disk decoder used to spell u32::from_le_bytes( b[..4].try_into().unwrap()); the slice was always pre-checked, but a runtime that opens third-party files should not carry an unwrap on its parse path at all (clippy::unwrap_used is denied workspace-wide). A wrong length here is a decoder bug surfaced as UnexpectedEof.

chunk

Canonical chunk types and chunk_id derivation.

encoding

section payload encoding (raw / zstd / float16 / int8).

error

layout

.urna binary file layout (v1)

manifest

Manifest types and constants. The validate impl lives in manifest::validate; the canonical-JSON serializer in manifest::canonical. This module owns the data shape only.

reader

Zero-copy view over a .urna byte slice.

sections

Section payload formats (v1).

writer

Builder for .urna files.
