Abstract
A methodology is presented for building knowledge-based systems that reason by explaining. The methodology is the basis for RATIONALE, a tool-implemented in Quintus Prolog- that ties together the processes of knowledge acquisition,expert system construction, and explanation of system reasoning. RATIONALE integrates explanations with reasoning by using domain knowledge together with explicitly represented strategies. Reasoning proceeds by constructing a hypothesis tree whose root contains the most general diagnosis of the expert system. Guided by a focusing algorithm, the tree branches into more specific hypotheses that explain the more detailed symptoms provided by the user. As the expert system is used, the hypothesis tree also serves as a dynamically generated explanation tree.>

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
