You can pack multiple genres into a single byte bitfield to enable efficient multi-genre classification and fast queries across large datasets. This approach minimizes storage overhead and accelerates per-genre dispatch.

Filtering multiple object kinds simultaneously is best handled by maintaining per-genre sub-queries against a packed genre bitfield. This allows you to apply per-genre filtering with minimal overhead across Zettel, Tag, Type, and Repo objects.

Sigil-to-genre mapping works by parsing short sigils like :z, :t, :e, :r, and :b and mapping them to their corresponding genres. This provides an intuitive shorthand for executing multi-genre queries.

Yes, you can use a dedicated Genre enum alongside a bitfield wrapper with conversion utilities to optimize dispatch. This model provides the necessary structure to convert genres into bit integers for fast filtering.

Multi-genre classification requires a bitfield approach because non-bitfield methods incur overhead and slow down per-genre dispatch. Packing genres into a single byte ensures compact storage and enables scalable queries across large datasets.

Using a single byte bitfield for genre storage limits classification to a maximum of eight distinct genres. You should not use this approach if your system requires managing more genres than a single byte can represent.
