How rarity follows the stars
The catalog gathers public repos with at least 100 stars. RepoMasters splits them into six tiers with round thresholds, the same for every language: the more stars a repo has, the higher its tier, and the rarer it is in the catalog.
Each pull first picks a tier using the published odds, then a random repo among those that carry it. A giant is therefore rare to pull and a small project common: on average, an LTS shows up in 1 floppy out of 200.
Living rarity
Stars change, and so does the tier. Every night, RepoMasters rechecks the stars across the whole catalog: a repo that crosses a threshold changes tier for every copy, up or down.
Early adopter
Pulled a repo before it took off? If one of your cards climbs at least 2 tiers after you get it, reaching Beta or higher, it earns the Early adopter badge: you keep it even if the repo drops back, and it pays 10 bytes per tier gained.
