Skill capability stays a hard filter, so a multi-skill tech (e.g. an
installer who also has the repair skill) can take those jobs. But the
specialist bias (skill-order rank) was too strong (6 virtual min/rank),
so a far repair-specialist beat a nearby installer-who-repairs. Lower
rank_weight to 2 → distance dominates; specialty only breaks near-ties.
Verified: repair job near a rank-3 multi-skill installer (4 min) vs a
far rank-0 specialist (14 min) — old weight picked the far specialist
(bug), new weight picks the nearby installer.
