What's in the box

Type Purpose
ISellable Marker: something sold at line level, identified by Sku.
ISellableProduct ISellable + optional Name, CategoryPath, BrandRef, UnitPrice, UnitCost.
ISalesTransaction / ISalesLine A basket / receipt and its lines.
ITransactionSource The one port the engine consumes: IAsyncEnumerable<ISalesTransaction> for a DateRange.
IProductCatalog Optional SKU → product lookup for category / margin-aware analyses.
Model.* Plain SellableProduct / SalesLine / SalesTransaction records + InMemoryTransactionSource for tests and small jobs.
Primitives.DateRange Inclusive-start, exclusive-end instant range. 
public sealed class OrderSource(MyDbContext db) : ITransactionSource
{
    public async IAsyncEnumerable<ISalesTransaction> GetAsync(
        DateRange window, [EnumeratorCancellation] CancellationToken ct = default)
    {
        await foreach (var order in db.Orders
            .Where(o => o.PlacedAt >= window.Start && o.PlacedAt < window.End)
            .AsAsyncEnumerable().WithCancellation(ct))
        {
            yield return new SalesTransaction(
                order.Id.ToString(),
                order.PlacedAt,
                order.Lines.Select(l => (ISalesLine)new SalesLine(l.Sku, l.Qty, l.Net)).ToList(),
                CustomerRef: order.CustomerId.ToString());
        }
    }
