# Chapter 12, claim 4, the promises

Due 31 December 2027

**The test.** Falsified if three in four or more of the dated promises that have matured and can be scored by then were kept on their promised phase dates, scored as the slippage matrix scores them, on evidenced load and not the builder’s word.

held Held so far. Of the five dated promises that had matured, one could not be scored; of the four scorable, two were missed outright, one was kept only on the builder’s own account, which the test does not count, and one was missed unless “early 2026” means the first quarter: at most one of four kept, under the three-in-four line.
