Marshalling: Data-Oriented Serialization
summary
After 30 years of Java Serialization the proposal replaces object-scraping with language-level constructor-based marshalling and matching deconstructors as schemas, making structure explicit (types, names, order) and decoupling wire formats. Prototype integrates with Jackson in under 100 lines and the PoC runtime is ≈1,000 Java lines. It drops serialVersionUID/readObject/writeObject magic, disallows automatic cycles, supports constructors and static factories (enums/singletons via factories), and lets authors opt in to private access for safe, versioned migration.
