-- Contextual source reliability (review pass §7.2 item 14). Reliability is
-- recorded per (source family, domain) from prediction outcomes and operator
-- corrections; a source's standing in one domain never moves its standing
-- in another, and the trust-level credibility itself is never rewritten.
