Abstract
many metropolitan areas in the world currently face challenges of rapid urbanisation. at the urban peripheries, the balance between 'urban areas' designated for new settlements for city inhabitants and 'green areas,' which provide ecosystem functions, has come under heavy pressure because of this rapid urbanisation. Spatial planning research provides methods for a thorough evaluation of urban development strategies. in this paper, a method is proposed that provides a systematic Suitability assessment for the metropolitan territory, from the perspective of both urban planning basic principles and environmental sustainability. this approach, which combines analytical Hierarchy Process (aHP) and geographic information System (giS) techniques, is applied to a case study in istanbul, turkey, to evaluate current urbanisation patterns. beykoz district spans an area of more than 30,000 ha at the anatolian side of istanbul, along the bosphorus. currently 79% of the total area is forested, 15% is agricultural land and 6% is urbanised. these characteristics make it a unique and financially precious area. it is thus particularly important to ensure that urban planning and development in this district are sustainable. in the Suitability assessment, six main parameters are included, namely slope, streambed, natural conservation status priority, forested areas, agricultural areas and watershed areas. twenty-four sub-parameters are weighted by the aHP technique and integrated levels of suitability are determined by weighted overlay using giS. the final map produced using this combined technique shows how urban constructions are spreading on the urban fridge of the beykoz district. the resulting suitability map provides for a better comprehension of alternative settlement locations for preserving nature and sustainable development. the systematic and fact-based characteristics of the described methodology add to the legitimacy of its outcomes. the proposed method can serve as a suitability assessment instrument to analyse future urbanisation plans on their wider implications in terms of sustainability.

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 it
