Research direction

Start at the TableMetadataV3 serialization path that currently raises NotImplementedError, then read the Version 3 specification linked in the issue. Trace the existing table-creation and v2 upgrade paths to identify the affected entry points. Done means V3 metadata serializes, new tables use format-version=3, and v2 tables can be upgraded.
