# transferLaneRanking

query · in the family [Reading your records](/reference/reading-your-records/)

## What it does

Which transfer lanes (location pairs) serve a move best, ranked.

The resolved sourcing matrix into ONE destination: every ACTIVE source LF as a row — stored lanes (never/always/ranked) + the sparse geodistance DEFAULT ordering (LF→PF→PFL.geo; a geo-absent side ranks LAST flagged no-geo; same-PFL light out-ranks shipped at equal distance). never entries are SHOWN position-less (excluded from consideration — an INACTIVE lane is ABSENT, not never). DERIVED at read. Requires authentication.
