Encoding format

- *

- * The codec supports two on-wire formats: - *

- * + * Closed binary codec for the current filesystem persistence schema. * *

- * The compact format eliminates the pathological overhead of writing a full - * Java class name for every scalar value (e.g., {@code boolean}). It also - * substantially reduces class-loading activity during decode. + * Every payload carries a fixed magic value, one current codec version, and one + * of ten explicit top-level type identifiers. Nested values are decoded only + * through the schema selected by trusted store code. Java class names are never + * persisted or resolved, and this codec performs no runtime class loading, + * reflective construction, or factory discovery. *

* - *

Type compatibility

*

- * During decode, the codec enforces that the encoded value type is compatible - * with the expected type. Primitive/wrapper pairs (e.g., - * {@code boolean}/{@link Boolean}) are treated as compatible because values are - * boxed when represented as {@link Object}. + * Pre-release payloads written by earlier class-name-based codecs are rejected. + * No compatibility or migration decoder is provided. Lists and optional values + * carry their exact element schema, and attribute sets are represented + * structurally and decoded to {@link SimpleAttributeSet}. *
