"""Rubric scoring for Bike-Tinder, ported verbatim from the hunt's
|
||||
reference/motorcycle-hunt-rank.py (family tiers + extras + veto + price fit).
|
||||
|
||||
The hunt's ranker drops rows with no family match (returns None). Bike-Tinder
|
||||
shows everything, so an unmatched/vetoed row scores 0 and sorts below scored
|
||||
rows (docs/DATA-MODEL.md: "Unscored rows sort below scored ones; nothing is
|
||||
hidden").
