Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

The Swedish Navy’s Visby corvette is designed to be virtually invisible in pursuit of hostile submarines and underwater mines. The Visby is designed to be difficult to detect by an enemy using radar, infrared, hydro-acoustic monitoring or any other sensor system. The craft’s success could change naval warfare as profoundly as did the ironclad ships in the 19th century. Sweden’s YS2000 class corvette, the first known production naval stealth vessel, takes shape at Kockums’ shipyard on Karlskrona Island. The Kockums shipwrights designed the Visby to be electronically undetectable at a range greater than 13 km in rough seas, and at more than 22 km in calm seas, without electronic jamming. With the assistance of jamming, the Visby is invisible at more than 8 km in rough waters and 11 km in a calm sea. Computing Devices Canada also designed a monitoring system so that the Visby can perform a background check on its own vibration levels to ensure that the ship’s sound is within acceptable levels.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
