The rule that saves the run
Progress is not the rarest Egg you can touch. Progress is the Egg you can carry home, hatch and use to make the next run safer.
01
Record the base Pet
Write down the unmodified income first.
02
Apply observed modifiers
Keep community reports separate from confirmed values.
03
Recheck after updates
A mutation page is only useful when its date is visible.
What to record
Keep the current Biome, Speed requirement, Guardian, Egg source and Pet income together. When an update changes one field, the connected records need a fresh check too.
Evidence boundary
Mark uncertain spawn rates, mutation multipliers and expired rewards as unverified until you test them in the current experience.
