Achievements can have a practical benefit, or they can just reward the user with stardust (which is used to unlock new technology as per the user’s desires).

Achievements, Milestones, and Skill Progress

Achievements are persistent badges for players — e.g. “10 Planets Discovered”, “5 AI4M Routes Completed”, etc. These may unlock new types of missions, tech, or tools.

Milestones are time-sensitive community goals (weekly, per-project), and should award Stardust.

The /next/{classificationId} route should eventually show:

  • Progress toward related skill badges
  • Remaining steps in inspection/follow-up missions
  • Additional actions (e.g., bonus missions)

Voting and consensus actions should also contribute to achievements and Stardust rewards.
