Release v0.7.0 · panproto/didactic

Added

tuple[Model, ...] (and dict[str, Model], plain inner: Model) now classifies any dx.Model subclass used directly as a field type. The classification routes through the same Embed-shaped translation that Embed[T] would have built, so the wire format and runtime semantics are identical and callers no longer need a single-variant TaggedUnion wrapper to collect heterogeneous record tuples. Models that are TaggedUnion roots or variants stay on the discriminated path. (#38)
dx.field(opaque=True) declares a field that holds any Python value by reference and skips the type-classification pipeline entirely. The runtime stores the value on a per-instance _opaque_storage side table; attribute access returns it identity-equal; with_(...) updates it without re-classification. JSON output writes null for opaque fields, and model_validate_json does not reconstruct the value: opaque fields explicitly do not round-trip through serialisation. Useful for fields that carry a runtime-only handle (a typeclass instance, a callback, a foreign object) where panproto schema integration is not the goal. (#39)

The documentation site uses the cinder theme. The previous Material configuration is replaced by theme: name: cinder plus a small docs/css/ palette covering pygments token colours and mkdocstrings layout. CI no longer needs the NO_MKDOCS_2_WARNING workaround; the same env var has been removed from ci.yml / docs.yml / release.yml and from the README's local-build snippet.
