Self-hosted trip tools are personal knowledge infrastructure

Self-hosted trip tools are more than replacements for travel apps.

They can preserve personal context across trips: routes, places, notes, media, expenses, weather patterns, and lessons learned. That history becomes more useful when it is owned, searchable, and linkable.

This makes travel planning part of a personal knowledge system instead of a one-off booking workflow.
