Abstract
All alternate transportation fuels require infrastructure to support widespread use of the new fuel. For example, in Canada in the mid-1980's, NGV markets were being developed in a number of urban settings in Canada supported by fuelling stations offering NGV and by conversion dealers who could install aftermarket conversions and maintain them. Canada's major NGV equipment supplier, CNG Fuel Systems, helped to create the infrastructure by co-investing in fuelling stations and creating a network of authorized dealers. Profitability issues arose for each. For refueling stations, the rate of buildup of fuel usage per station became the key financial performance criterion. For conversion dealers, initial pricing strategies (which reflected traditional margins in auto parts) created too large a markup for conversions, which limited sales prospects. Modified approaches to conversion pricing focused on constant “bay day” revenue for the dealer, with limited success. In each case, the objective was to develop an overall market infrastructure in which each component was sufficiently profitable to motivate ongoing investment. Failure to achieve profitability in the infrastructure components affects the growth in usage of an alternate fuel.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
