What the final index will record
Each row needs enough context to survive a game update rather than becoming another copied tier list.
- Pet name and source egg
- Biome and displayed rarity
- Base income shown on a dated pet card
- Size or Mutation visible on that exact pet
- Capture date and game version context
Why we are not publishing a winner yet
Current guides disagree about the number of pets and the highest earner. Size and Mutation rolls can make two copies of the same pet show different income, so a clean baseline matters more than a dramatic headline.
