About
Prewe is the one who gets clear at chapter 5. The map requires that part of the chapter 5 cell breaks off and escapes, because otherwise the outfit's chapter 19/chapter 21 competence is asserted advantage — forbidden by item 8: "his advantage is position, never asserted genius… position is showable." So Prewe is the source. What the outfit knows at Threap is exactly what Prewe saw and reported: 1. Kestrel left a route for a distress squawk. She will divert. That single fact is the whole of what chapter 21 needs. 2. Which way she turns under load.
