Abstract
The name Alcan might be synonymous (well, perhaps to older readers!) with a popular brand of aluminium foil but there are deeper connections with occupational medicine extending into the Society of Occupational Medicine and golf. Alcan was a Canadian mining company and aluminium manufacturer. The name was derived from the Aluminum Company of Canada and was one of the world’s largest aluminium manufacturers. It is now a subsidiary of the multi-national Rio Tinto group. Despite the well-known tinfoil brand, it and its alloys are essential to the aerospace industry and widely used in building for facades and window frames. Aluminium has a remarkably low density and ability to resist corrosion through the phenomenon of passivation where a material becomes passive and less affected or corroded by the environment of future use. Aluminium production is typically achieved by extracting aluminium in a smelting process from its oxide, alumina, generally by what is known as the Hall–Héroult process. Alumina is also extracted from the ore bauxite by means of the Bayer process at an alumina refinery. Because this is an electrolytic process, an aluminium smelter uses huge amounts of electricity. Smelters often tend to be located close to large power stations, often hydro-electric ones, to reduce the overall carbon footprint. This is an important consideration, because a large amount of carbon is also used in this process, resulting in significant amounts of greenhouse gas emissions. There is now only one remaining smelter in the UK left, Liberty British Aluminium. Based at Fort William in the Scottish Highlands, the smelting facilities are powered by two neighbouring hydro-electric stations. This combination of renewable energy sources makes the site one of the greenest metal production plants in the country. Up until 2000, there had also been another smelter at Kinlochleven in the Highlands, constructed in 1907. Smelting has a wide range of occupational hazards including heat stress, noise, EMF exposure, respiratory symptoms including obstructive and restrictive defects and the colloquially known ‘potroom asthma’, a condition somewhat specific to the industry, and a continuing although not established concern around cancer. Those wide and varied health concerns make occupational health a critical business component and that in turn links us to the Scottish Group of the Society of Occupational Medicine who play annually for the Alcan golf Trophy. The origins of the trophy remain somewhat shrouded in mystery, presumably we think, an Occupational Physician providing services to Alcan persuaded them to donate this trophy and we would be keen if any reader has more information to get in touch. So, the next time you wrap your chicken or other food item in tinfoil, you will think about the history and challenges of this fantastically useful multi-purpose culinary tool.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
