Abstract
This chapter investigates uniformed patrols called ‘ambassadors’, who are increasingly providing security in the nooks and crannies of city centre cores across many countries. These programmes migrated from US cities like Baltimore and Philadelphia to cities in Canada, then to the UK cities, and far beyond, and are intimately connected with urban ‘revitalisation’ and mostly class-based gentrification strategies. Interviews with public police and ambassadors in three Canadian cities reveal that ambassador operations and practices are shaped and made possible by relations with police that entail exchanging knowledge for limited training and tacit tolerance. Ambassadors act as police ‘eyes and ears’ and govern ‘nuisance’, using indirect and unauthorised strategies. In these arrangements, ambassadors are not so much ‘steered’ by police as ‘anchored’, suggesting notions of ‘networked governance’.

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.
