Turns each KNOWN-UNKNOWN in a Fetchproof project into the first tasks of the build - the day-one verification step its row names becomes a task, a smoke test or a guarded check, done before anything that depends on it. Use at the start of phase 2, when planning the first build steps from research/BRIEF.md, or when the user asks what to do first.
