Quick answer
When a building is starved, inspect its input source list before adding more production. A direct local producer can beat a full warehouse if the warehouse route is long, while a warehouse is safer when several consumers share one reserve.

Source selection routine
- Select the hungry building and list every available input source.
- Compare local stock, route length, connection type, and Fetcher travel.
- Keep one reliable reserve source enabled instead of chasing the nearest empty node.
- Run the chain briefly and confirm the input rises before changing another link.
- Document the source choice when a patch or rebuild changes the result.
FAQ
Should every building use the nearest source?
No. Reliability and reserve matter as much as distance; a nearby producer with no output is not a useful source.
Can I use a direct producer and warehouse together?
Yes. Multiple sources can provide resilience, but they still need valid connections and available output.
