# Kept line

A station rewrite keeps one Fresh line and drops the copies. `Skills:` and `Keys:` are kept the same way when the new card does not already carry them. A fleet `Plane:` (core, integration, ecosystem, distribution, live) replaces the stock plane line.

mergeStationMarkdown in src/integrations/hooks/station-hook-runtime.cjs treats a Fresh line as stock. Copies are not preserved. When the new card has no Fresh line, the latest one is kept. The plates that belong here are station-card and work-fresh.
