Value Operations

Value provides two kinds of operations:

• Static - pure functions on any value without a schema: Operations.clone, Hash.value, Value.diff, Operations.patch
• Instance - schema-aware operations via jt.value.*: cast, clean, convert, create, instantiate

Methods

Method	Kind	Description
Operations.clone / Hash.value	Static	Deep copy; deterministic hash
Value.diff / Operations.patch	Static	Structural diff; apply a single operation
value.cast / clean / convert	Instance	Type coercion, stripping, conversion
value.create	Instance	Zero-value instance for blank form state

All examples use the bookstore domain.
