 *   on `.build`, so callers can pass plain (e.g. deserialized) objects and still receive typed instances
 * .how =
 *   - single option → build directly into it
 *   - multi-option + `_dobj` discriminator → build into the named option (try-each skipped)
 *   - multi-option, no `_dobj` → disambiguate by strict-schema try-each (failfast on loose/absent schema, zero, or many fits)
 * .note = a null or absent (undefined/primitive) nested value is left untouched — a nested field may be
 *   nullable or optional, and no DomainObject would validate a non-object, so hydration is a no-op there
