F.1:5.5 - Didactic distillation of source selection

State and independently identify the question; keep the later use in the claims. Keep a source because an inspected claim can change the answer, expose a rival or counterexample, or mark a transfer limit. Return one finite SourceCutNote whose ClaimGraph carries those roles, exclusions, limits, and reopen conditions, whose EntityOfConcern is the exact question, and whose named effective scheme resolves the question and exact editions. Search scores may guide inspection; they do not admit or exclude a source. Stop when additional candidates do not change the answer.
