What does a PortfolioPNLDetail represent? My understanding reading through the code is that these could be individual trading lots (single purchases or sells for an asset)?

PortfolioSwaprepresents either a buy or a sell transaction, depending on which token is the base token.PortfolioPNLDetailrepresents either a partial lot of a full lot. It also represent a line item in the PNL report.PortfolioRealizedPNLDetail: this represent either a partial of full lot that has a matching sell transaction. The sold asset represent the amount of the position that was sold.sold_assetis computed in a way so that there is only one buying and selling price.PortoflioUnrealizedPNLDetail: a full or partial lot that has no matching sell transaction

How do we know the PNL without setting a base currency we check against?

When the computation of the PNL is call, the base currency/token is passed as a parameter. That base token is passed to the PNL report.
This function here is a helper function on the report itself, so the base token is already known

Does the PortfolioSwap sold not already include the assets sold?

asset_sold, represents the amount of asset being sold for that line item. Maybe a better name would be amount_sold.
It is different than the PortfolioSwap sold because the sell transaction may impact multiple positions.
