Abstract
We’re standing in the exact same spot. But you’re in a 15-minute city and I’m not. Why? We examine the City of Nanaimo, British Columbia, to find (overlapping amenity isochrone) zones where residents can live and have 15-minute walking access to “essential” (grocery, pharmacy) and “basic quality of life” amenities (recreational space, library, museum/gallery/theater/cinema, restaurant/pub, and cafe/coffee), but also daycares, public schools, foodbanks, and walk-in clinics. Depending on one’s needs, there are different 15-minute walking zones within the City. As one’s needs increase, fewer and smaller residential zones continue to qualify as 15-minute walkable. Of all the city neighbourhoods, downtown and downtown-adjacent Nanaimo offer the most extensive 15-minute walkability for residents, even residents with the most extensive needs. Initial investigation suggests that these zones offer affordable shelter for most of the top three income quintiles, but are on average unaffordable for those in the two lower income quintiles. Amenity overlap is greatest in residentially dense areas, and residential density provides more residents with walkability to existing amenities (and amenity owners with a proximate consumer base). As a result, A) zoning to permit density-increasing developments around amenity concentrations and, conversely, amenity development in areas of greater residential density (as well as pedestrian-friendly infrastructural improvements) – or B) combined amenity-residential density zoning in areas lacking both – would improve 15-minute walkability in the City of Nanaimo.

How this classification was reachedexpand
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.
