Pure News Intelligence · one-page research-results summary
Negative and null results were preserved rather than tuned away.
1 · Combined multisource model
Question: Did 10-K information improve an existing 8-K and inexpensive-news model?
Result: No incremental improvement was supported.
Decision: Do not claim incremental alpha.
2 · Expected-disclosure model
Question: Did characteristics, 8-Ks, and news predict the next filing representation better than the prior 10-K alone?
Result: The prior 10-K persistence baseline performed better.
Decision: Stop added modeling complexity at this gate.
3 · Disclosure-change demonstration
Question: Can the system identify, evidence, and check meaningful changes?
Result: The workflow was operational; the bounded risk test was inconclusive.
Decision: Advance to an analyst workflow pilot—not trading deployment.
Claim boundary
Supported: document processing, historical comparison, point-in-time integrity, evidence extraction, reproducible classifications.
Not supported: alpha, causal prediction, improved expected-language reconstruction, adoption, willingness to pay.
Not tested: time savings, recall, trust, repeat use, institutional-memory value.
