Cap — where it appears

A ceiling on how deep a parse’s chain of copies may go, enforced while the parse runs. It converts an unbounded extraction cost into a stated one and is paid for in phrases, at a rate that is steep below a collection’s mean depth and negligible above its worst.

The deepest text is punctuation

Eight source files reach depth 78 in a parse, on a collection with no version history in it at all. The positions between depth 20 and depth 72 are the same 48 characters at every level, and every one of them is a dash in a comment separator.

The cap that would ship

The published sweep put the knee at four to eight. On four real collections it is at nine to twelve, a cap of one costs forty-eight times the free parse rather than twenty-one, and the number a system should actually set is none of those.
