The proof challenged the earlier shortlist, demoted weaker candidates, and kept power only after narrowing it to monthly generator and plant transition intelligence.
EIA-860M became the monthly structural event spine. Annual EIA-860 became the reconciliation backbone. EIA-923 became the operating significance layer.
Snapshots, generators, plants, normalized change events, proposal credibility facts, and retirement significance facts were treated as distinct layers.
The diff logic converted raw monthly changes into interpreted events: new proposals, COD movement, material capacity changes, retirements, cancellations, and transition fingerprints.
The proof explicitly avoided collapsing everything into one fake-precise score. It asked what matters, how confident the interpretation is, and what deserves human review.
Noise, weak signal quality, cross-grain inference risk, pseudo-precision, and drift into vague energy-transition storytelling were all identified before the deck appeared.
