P3 review: asset bases and the tax-basis K-1

Schema 13 is as shipped and the asset columns are schema 14 (shipped
migrations pinned by hash); the tax-basis K-1 leaves net income open (only
the return has it) and takes a contributed prepaid plan at its book amount
as its section 723 basis; a disposal of contributed property names its
704(c) gain or loss; aliases compare by meaning; fixture amounts made up.
