Profile nudge priority and achievement governance

DEC-0049 - Profile nudge priority and achievement governance

Context

Goal optional policy was confirmed, but profile-completion execution, achievement behavior, and nudge arbitration still lacked concrete rules.

Decision

Nudge and profile-completion governance:

• If both goal and profile are incomplete, nudge priority is goal-first.
• Combined nudge cap is global 1 per day per account.
• Badge visibility strategy:
  • profile-first,
  • with light Home mention.
• Profile completion recalculates live from current profile data.
• Profile info visibility default is private.

Achievement governance (V2):

• Scope is track + display only in V2.
• Milestone reward is one-time per milestone (anti-abuse).
• Social sharing is deferred, but data model remains sharing-ready.

Profile field behavior:

• Display-name is optional; fallback uses auto-generated friendly nickname.
• Social signup can seed display-name from social username.
• Academic profile focus is Program + Score goal with partial completion allowed.
• Payment milestone is visible for all users and weighted in completion model.

Decision Value

• Keeps nudges effective without overwhelming users.
• Enables future achievement expansion without shipping heavy gamification now.
• Aligns profile model with optional-goal strategy while preserving measurable completion behavior.

Rationale

A lightweight achievement layer works as motivation now and as infrastructure for future social/reward rollout, without introducing mandatory gates.
