- F1: Set seed jury/mentors/observers to NONE status (not invited), remove passwords
- F2: Add bulk invite UI with checkbox selection and floating toolbar
- F3: Add getProjectRequirements backend query + requirement slots on project detail
- F4: Redesign filtering section: AI criteria textarea, "What AI sees" card,
  field-aware eligibility rules with human-readable previews
- F5: Auto-redirect to pipeline detail when only one pipeline exists
- F6: Make project names clickable in pipeline intake panel
- F7: Fix pipeline creation error: edition context fallback + .min(1) validation
- Pipeline wizard sections: add isActive locking, info tooltips, UX improvements
