+**Debug & Development Tools (26.03.2026):**
+- ✅ **Comprehensive Debug System:**
+  - Test-Button in Prompt-Editor mit Debug-Modus
+  - Shows resolved/unresolved placeholders
+  - Displays final prompts sent to AI
+  - Per-stage debug info for pipelines
+  - Export debug data as JSON
+- ✅ **Placeholder Export (per Test):**
+  - Button in Debug-Viewer
+  - Exports all placeholders with values per execution
+- ✅ **Global Placeholder Export:**
+  - Settings → "📊 Platzhalter exportieren"
+  - All 32 placeholders with current values
+  - Organized by category
+  - Includes metadata (description, example)
+- ✅ **Batch Import/Export:**
+  - Admin → "📦 Alle exportieren" (all prompts as JSON)
+  - Admin → "📥 Importieren" (upload JSON, create/update)
+  - Dev→Prod sync in 2 clicks
+
+**Placeholder System Enhancements:**
+- ✅ **6 New Placeholder Functions:**
+  - `{{sleep_avg_duration}}` - Average sleep duration (7d)
+  - `{{sleep_avg_quality}}` - Deep+REM percentage (7d)
+  - `{{rest_days_count}}` - Rest days count (30d)
+  - `{{vitals_avg_hr}}` - Average resting heart rate (7d)
+  - `{{vitals_avg_hrv}}` - Average HRV (7d)
+  - `{{vitals_vo2_max}}` - Latest VO2 Max value
+- ✅ **7 Reconstructed Placeholders:**
+  - `{{caliper_summary}}`, `{{circ_summary}}`
+  - `{{goal_weight}}`, `{{goal_bf_pct}}`
+  - `{{nutrition_days}}`
+  - `{{protein_ziel_low}}`, `{{protein_ziel_high}}`
+  - `{{activity_detail}}`
+- **Total: 32 active placeholders** across 6 categories
+
+**Bug Fixes (26.03.2026):**
+- ✅ **PIPELINE_MASTER Response:** Analysis page now uses unified executor
+  - Fixed: Old `/insights/run` endpoint sent raw template to AI
+  - Now: `/prompts/execute` with proper stage processing
+- ✅ **Age Calculation:** Handle PostgreSQL DATE objects
+  - Fixed: `calculate_age()` expected string, got date object
+  - Now: Handles both strings and date objects
+- ✅ **Sleep Quality 0%:** Lowercase stage names
+  - Fixed: Checked ['Deep', 'REM'], but stored as ['deep', 'rem']
+  - Now: Correct case-sensitive matching
+- ✅ **SQL Column Name Errors:**
+  - Fixed: `bf_jpl` → `body_fat_pct`
+  - Fixed: `brust` → `c_chest`, etc.
+  - Fixed: `protein` → `protein_g`
+- ✅ **Decimal × Float Type Error:**
+  - Fixed: `protein_ziel_low/high` calculations
+  - Now: Convert Decimal to float before multiplication
+
 **Migrations:**
 - Migration 020: Unified Prompt System Schema
