Created comprehensive redesign document addressing all identified issues:
Problems addressed:
1. Primary goal too simplistic → Weight system (0-100%)
2. Single goal mode too simple → Multi-mode with weights
3. Missing current values → All goal types with data sources
4. Abstract goal types → Concrete, measurable goals
5. Blood pressure single value → Compound goals (systolic/diastolic)
6. No user guidance → Norms, examples, age-specific values
New Concept:
- Focus Areas: Weighted distribution (30% weight loss + 25% endurance + ...)
- Goal Weights: Each goal has individual weight (not binary primary/not)
- Concrete Goal Types: cooper_test, pushups_max, squat_1rm, etc.
- Compound Goals: Support for multi-value targets (BP: 120/80)
- Guidance System: Age/gender-specific norms and examples
Schema Changes:
- New table: focus_areas (replaces single goal_mode)
- goals: Add goal_weight, target_value_secondary, current_value_secondary
- goals: Remove is_primary (replaced by weight)
UI/UX Redesign:
- Slider interface for focus areas (must sum to 100%)
- Goal editor with guidance and norms
- Weight indicators on all goals
- Special UI for compound goals
Implementation Phases: 16-21h total
- Phase 2: Backend Redesign (6-8h)
- Phase 3: Frontend Redesign (8-10h)
- Phase 4: Testing & Refinement (2-3h)
Status: WAITING FOR USER FEEDBACK & APPROVAL

Key Decision: Minimal Goal System BEFORE Placeholders
Critical Finding:
- Same data = different interpretation per goal
- Example: -5kg FM, -2kg LBM
- weight_loss: 78/100 (good!)
- strength: 32/100 (LBM loss critical!)
- Without goal: 50/100 (generic, wrong for both)
Recommended Approach (Hybrid):
1. Phase 0a (2-3h): Minimal Goal System
- DB: goal_mode field
- API: Get/Set Goal
- UI: Goal Selector
- Default: health
2. Phase 0b (16-20h): Goal-Aware Placeholders
- 84 placeholders with goal-dependent calculations
- Scores use goal_mode from day 1
- No rework needed later
3. Phase 2+ (6-8h): Full Goal System
- Goal recognition from patterns
- Secondary goals
- Goal progression tracking
Why Hybrid Works:
✅ Charts show correct interpretations immediately
✅ No rework of 84 placeholders later
✅ Goal recognition can come later (needs placeholders anyway)
✅ System is "smart coach" from day 1

- Normal-Modus: Nur Einzelwerte (übersichtlich)
- Experten-Modus: Zusätzlich Stage-Rohdaten
- Beschreibungen für alle Platzhalter vervollständigen
- Schema-basierte Beschreibungen für extrahierte Werte
Aufwand: 4-6h, Priority: Medium
