Versioned data serialization embeds type metadata using a boundary-based format with leading and trailing '---' markers and a type metadata line starting with '!'. This structure enables version-aware encoding by mapping type strings to registered decoders for structured blob payloads.

Boundary-based serialization delimits typed data with '---' separators to clearly mark payload boundaries. You need it for configuration blobs and serialized objects when storing multiple versioned data types that require metadata-driven routing to specific decoders.

Metadata-driven routing uses a coder registry that maps type strings to versioned decoders. During deserialization, the type metadata line dynamically routes the payload to the appropriate decoder via a type map, selecting the correct version handler automatically.

Yes, you can use this versioned data serialization format without external dependencies. It operates independently through an internal coder registry and boundary-based on-disk format to manage typed blob encoding and decoding.

The best way to debug serialization issues with versioned typed blobs is to inspect the boundary-based format, verifying the leading and trailing '---' markers and the type metadata line starting with '!'. This confirms correct versioned coder routing.

A limitation of using boundary markers for structured blob serialization is that payloads containing the '---' delimiter may interfere with format parsing if not properly escaped. The format relies on strict boundary adherence for accurate versioned decoder routing.
