derive-independently-then-compare

Derive an answer from the source corpus a second time, without reading the first derivation, then compare — before trusting a conclusion drawn from a large body of transcripts, notes, or documents about what someone wants, prefers, or constrains. Use when a claim about a person's stated intent or a parameter cannot be traced to a quote, or before that claim is reported as fact. Runs before sanity-check and devils-advocate, not instead of them — a reviewer or an opposing case inherits whatever inputs the first pass fabricated, and this is the only one of the three that re-reads the source rather than the write-up. Not ask-a-council (different positions on a shared question, not the same question re-derived from source); not determine-signals (finds what was already checked, not whether what was reported was actually found there).
