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.

aboutThe title or abstract carries a Canadian signal from the geographic lexicon.

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

Sandwich test units with two treated outer boards and one untreated center board were exposed at several test sites as part of a collaborative evaluation of aboveground test methods for a task force of the American Wood-Preservers' Association technical committees. Examination of material at a site in Vancouver, British Columbia, revealed that the untreated center boards between outer boards treated with chromated copper arsenate (CCA) were decaying more slowly compared to untreated center boards sandwiched between untreated outer boards or boards treated with 3-iodo-2-propynyl butyl carbamate (IPBC). Nondestructive analysis of the surfaces of the center boards provided estimated copper metal loadings of 0.6 mg/g wood on surfaces in contact with boards at 2.0 kg/m 3 CCA and 0.8 mg/g Cu on surfaces in contact with boards at 4.0 kg/m 3 CCA. Arsenic and chromium peaks were not detected. These results suggest that low levels of copper readily migrate during service and such movement can protect untreated wood exposed during checking from colonization by wood-rotting basidiomycetes.

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.
