Evidence status — patch sensitive: Unless noted otherwise, mechanics are verified against the installed patch 11.73 guide.
The installed 11.73 documentation conflicts with itself: its economy chapter derives +0.45 multiplier per standard resource-building level to reach 10,000/hour at level 20, while its building reference says +10% per level. Custom campaign presets can also change scaling. Trust the live Codex/base preview for the current world and use the formula structure—not the disputed coefficient—for planning.
