Narrative drift

Unsupervised drift from a company's own historical RNS narrative. Computes a centroid in embedding space for the historical corpus and the recent corpus, then measures the standard-deviation distance between them. 1.97× baseline cut rate over 180 days — the strongest single signal in the older model bank.

Useful precisely because it doesn't lean on hand-picked drivers — when a company starts talking about itself differently, that's the signal. Treat as a screen, not a recommendation.
