• The echo mistaken for an ancestor — how a CIA analyst's falsification checklist got read as an heir to symbolic AI, when the only lineage anyone could actually source ran to Bayes

• Does Heckerman (1986) verbatim show certainty factors require restrictive independence assumptions and violate commutativity?

• Bayesian networks are the real mechanism bridging classic AI rule-based inference engines and statistical inference — built to replace expert systems' ad hoc certainty-factor arithmetic with coherent probabilistic inference

• Heckerman (1986) showed MYCIN's certainty factors admit a coherent probabilistic reading only under restrictive independence assumptions

• MYCIN's certainty factors were an ad hoc non-Bayesian uncertainty scheme (CF = MB − MD) built for rule-based diagnosis

• The Pathfinder project rebuilt the same pathology-diagnosis task from rule-based reasoning onto Bayesian-network inference; its expert's blind verdict of improvement came at the Dempster–Shafer-to-simple-Bayes step

• Does the Pathfinder Part I paper verbatim support the rule-based → simple-Bayes switch and the expert's accuracy verdict — and where are the magnitude figures?

• Does Pearl's R-476 verbatim support that Bayesian networks were built to replace certainty factors as a coherent probabilistic alternative?

• The one peer-reviewed empirical ACH study (Dhami, Belton & Mandel 2019) compares ACH to Bayesian updating, not abduction, and never mentions Peirce

• A US intelligence-funded CS group reformulated Heuer's ACH as Bayesian networks, not as rule-chaining
