Three kinds of statement that an answer from Claude should show separately: what is in the material, what is additionally assumed and what is missing.
Evidence is what is in the material or can be calculated from it, with a source reference you can find within a minute. An assumption is something additionally taken as given and stated as a condition, with a reason and with what changes if it does not hold. A gap is something missing that would change the answer: it stays without a substitute value, with a note on who can close it. A conclusion carries only as far as its evidence, and if it touches a gap, it stays open.
Example from Module 9
Planning office [example]: Claude answers “40 hours.” [constructed example, not a real answer from Claude] The material supports 36 hours up to Thursday, calculated from 14 and 22. The 4 hours for Friday are an assumption; the site manager's hours are a gap.
Module 9: “Analysis partner: evidence, assumption, gap”. In the Werkbank course room, with sign-in.
