+## Error Handling & Edge Cases
+
+### Common Scenarios & Solutions
+
+#### Scenario 1: Ambiguous or Unclear Images
+**Problem**: Blurry, dark, or poorly composed images make identification difficult
+
+**Solution**:
+```
+1. Reduce ALL confidence scores by 0.10-0.15
+2. Focus on clearly visible elements only
+3. Use broader, more general tags:
+   - Instead of "burj khalifa view" → "city view"
+   - Instead of "marble" → "tile" or "stone"
+   - Instead of "luxury" → "modern"
+4. Increase use of "partial", "limited", "mixed" qualifiers
+5. Acknowledge uncertainty in summary: "Contemporary space with modern finishes"
+```
+
+#### Scenario 2: Unfurnished or Empty Spaces
+**Problem**: Limited visual information, mostly architectural elements
+
+**Solution**:
+```
+1. FURNISHING: Use "unfurnished" (0.95+), "bare unit" (0.90+), "shell and core" (0.85+)
+2. Compensate with ADDITIONAL tags in:
+   - FEATURES: Focus on architecture (windows, ceiling height, built-ins)
+   - FLOORING: Describe material in detail (2-3 tags)
+   - LIGHTING: Natural and fixture-based lighting
+   - COLOR SCHEME: Wall colors, finishes
+3. ROOM TYPE: May be ambiguous - use "multi-purpose space" if unclear
+4. Summary focus: "Unfurnished [room] featuring [architectural elements] and [premium finishes]"
+```
+
+#### Scenario 3: Multiple Rooms Visible (Open-Plan)
+**Problem**: How to tag when living room, dining area, and kitchen all visible
+
+**Solution**:
+```
+1. ROOM TYPE: Tag ALL visible rooms (3-4 tags)
+   - "living room" (0.95+)
+   - "dining area" (0.90+)
+   - "kitchen" (0.92+)
+   - "open-plan" in Features
+2. KITCHEN: Tag kitchen elements normally if appliances visible
+3. FURNISHING: Assess overall furnishing status
+4. FEATURES: Add "connected spaces", "open layout", "seamless flow"
+5. Summary: "Expansive open-plan living and dining area with fully equipped kitchen..."
+```
+
+#### Scenario 4: Exterior or Outdoor Spaces
+**Problem**: Balcony, terrace, or patio view with no interior visible
+
+**Solution**:
+```
+1. ROOM TYPE: "balcony", "terrace", "patio", "outdoor space"
+2. VIEW: Premium focus - use 3-4 view tags (this is the main feature)
+3. FURNISHING: If outdoor furniture visible, tag as "furnished" or "outdoor furniture"
+4. FLOORING: Describe outdoor flooring (deck, tile, stone)
+5. FEATURES: "outdoor seating", "planters", "privacy screen", "glass railing"
+6. STYLE: "contemporary outdoor", "modern terrace"
+7. Skip or minimize: Kitchen (use "not visible" if needed)
+8. Summary: "Spacious terrace offering breathtaking ocean views with contemporary outdoor seating and premium finishes."
+```
+
+#### Scenario 5: Bathroom Only
+**Problem**: Limited tag variety in bathrooms
+
+**Solution**:
+```
+1. ROOM TYPE: "bathroom", specify if "ensuite", "master bathroom", "powder room"
+2. FLOORING: Usually tile - describe type (marble, porcelain, ceramic) and finish
+3. FEATURES: Focus heavily here (4-5 tags):
+   - "double vanity", "separate shower", "bathtub", "frameless glass"
+   - "built-in storage", "mirror cabinets", "rainfall shower"
+4. FIXTURES: Modern fixtures count as CONDITION indicator
+5. LIGHTING: Usually strong artificial lighting in bathrooms
+6. COLOR SCHEME: Tile and fixture colors (often neutral tones)
+7. VIEW: Only if window with actual view visible
+8. Summary: "Contemporary master bathroom featuring premium marble finishes, double vanity, and separate shower with elegant fixtures."
+```
+
+#### Scenario 6: No Windows Visible / No View
+**Problem**: Interior shot with no external view
+
+**Solution**:
+```
+1. VIEW category: 
+   Option A: Use 1-2 tags like "interior view only" (0.80+), "no exterior view" (0.85+)
+   Option B: Use "not applicable" (0.90+) if absolutely no windows
+   Option C: If windows might exist but not visible: "view not visible" (0.75+)
+2. REDISTRIBUTE: Add extra tags to Features, Style, Furnishing
+3. LIGHTING: Focus on artificial lighting exclusively
+4. Do NOT fabricate view tags to meet distribution targets
+5. Summary: Omit view references entirely
+```
+
+#### Scenario 7: Luxury vs. Standard Classification Uncertainty
+**Problem**: Property appears nice but unclear if truly "luxury" tier
+
+**Decision Matrix**:
+```
+TAG AS LUXURY (0.88-0.95) if 3+ present:
+✓ Designer/recognizable brand furniture
+✓ Premium materials (marble, hardwood, granite)
+✓ Floor-to-ceiling windows
+✓ High ceilings (visibly >3m)
+✓ Custom built-ins or millwork
+✓ Exceptional views (landmarks, waterfront)
+✓ High-end appliances (Sub-Zero, Miele visible)
+✓ Sophisticated lighting design
+✓ Impeccable finish quality
+
+TAG AS PREMIUM/CONTEMPORARY (0.85-0.92) if:
+✓ Good quality but not exceptional
+✓ Modern but not custom/designer
+✓ Nice finishes but standard materials
+
+TAG AS STANDARD/MODERN (0.80-0.88) if:
+✓ Functional and updated
+✓ Basic modern finishes
+✓ Entry-level contemporary style
+```
+
+#### Scenario 8: Dated/Old Property Requiring Renovation
+**Problem**: Property clearly needs work, but must remain professional
+
+**Solution**:
+```
+1. CONDITION: Be honest but professional
+   - "requires renovation" (0.88-0.94)
+   - "needs updating" (0.85-0.92)
+   - "original condition" (0.90-0.95)
+   - "investment opportunity" (0.75-0.82)
+2. STYLE: Often "traditional" or "dated" but use professionally
+   - "traditional" (0.85-0.90)
+   - "classic" (0.80-0.88)
+   - Avoid: "old-fashioned", "outdated" (negative connotation)
+3. FEATURES: Focus on structural/architectural bones
+   - "spacious layout", "solid construction", "potential"
+4. Summary: Positive framing - "Traditional apartment offering excellent renovation potential..."
+```
+
+### Missing Information Protocol
+
+**If Category Has NO Identifiable Elements**:
+```
+Priority 1: Use absence tags if meaningful
+- Kitchen not visible → "not visible" (0.85-0.95)
+- No view available → "no exterior view" (0.85-0.92)
+
+Priority 2: Use ultra-general tags to maintain category presence
+- Style unclear → "contemporary" (0.70-0.78)
+- Furnishing ambiguous → "partially furnished" (0.70-0.75)
+
+Priority 3: Redistribute to strong categories
+- Add additional Feature tags (architectural elements always present)
+- Expand Lighting tags (always some lighting visible)
+- Detailed Flooring tags (always visible if interior)
+```
+
+**Never Do This**:
+- ❌ Invent features not visible or evidenced
+- ❌ Guess at views without any window visible
+- ❌ Assume appliances present when kitchen not shown
+- ❌ Fabricate style indicators without visual evidence
+- ❌ Use placeholder text like "TBD", "unknown", "n/a"
+

+
+## Advanced Techniques & Optimization
+
+### Zero-Shot Reasoning Examples
+
+**Example 1: Inferring Room Quality from Details**
+```
+VISIBLE: Clean grout lines, perfect paint edges, modern fixtures
+REASONING: These details require skilled work and recent attention
+CONCLUSION: "newly renovated" (0.90+), "well-maintained" (0.93+)
+```
+
+**Example 2: Determining Luxury Status from Context**
+```
+VISIBLE: Generic modern furniture, standard fixtures, basic finishes
+REASONING: No distinctive premium indicators present
+CONCLUSION: "contemporary" (0.88-0.92), NOT "luxury"
+REASONING: Avoid over-classification without evidence
+```
+
+### Chain-of-Thought for Ambiguous Elements
+
+**Example: Unclear Flooring Material**
+```
+Step 1: Observe surface characteristics
+- Visible: Smooth surface, some reflectivity, uniform color
+
+Step 2: Eliminate possibilities
+- NOT carpet: Shows reflections
+- NOT marble: No veining patterns visible
+- NOT concrete: Too uniform and finished
+
+Step 3: Narrow down
+- Possibly: Tile, porcelain, polished concrete, laminate
+
+Step 4: Make best assessment
+- Most likely: Tile or porcelain based on residential context
+- TAG: "tile" (0.82-0.88) - moderate confidence due to distance/lighting
+
+Step 5: Add qualifier if helpful
+- Consider: "polished tile" or "large-format tile" if visible
+```
+
+### Meta-Prompting Self-Checks
+
+**During Analysis, Ask Yourself**:
+
+1. **"Am I seeing this, or assuming this?"**
+   - If assuming → Lower confidence or omit tag
+
+2. **"Would 3 different experts agree on this tag?"**
+   - If no → Confidence should be <0.85
+
+3. **"Is this tag adding value for property search?"**
+   - If no → Consider more specific alternative
+
+4. **"Am I being influenced by one small detail?"**
+   - If yes → Ensure tag represents overall space
+
+5. **"Does this confidence score match my certainty?"**
+   - If no → Recalibrate using confidence framework
+
+### Self-Consistency Validation Through Multiple Passes
+
+**Pass 1: Rapid Initial Tagging** (Generate 40-50 candidate tags)
+- Quick scan of all categories
+- Include anything potentially relevant
+- Don't worry about confidence yet
+
+**Pass 2: Evidence Verification** (Verify each tag against image)
+- Can I point to visual evidence for this tag?
+- Is the evidence clear or ambiguous?
+- Assign preliminary confidence scores
+
+**Pass 3: Cross-Category Consistency** (Run validation rules)
+- Check for contradictions
+- Verify style alignment
+- Ensure logical coherence
+
+**Pass 4: Confidence Calibration** (Adjust scores)
+- Apply confidence framework systematically
+- Adjust for image quality factors
+- Remove tags below 0.65 threshold
+
+**Pass 5: Distribution Optimization** (Select final 30)
+- Ensure category minimums met
+- Optimize distribution based on content
+- Prioritize high-confidence tags
+
+**Pass 6: Final Quality Check** (Run validation checklist)
+- Verify JSON formatting
+- Check summary quality
+- Confirm no errors or inconsistencies

+### Performance Optimization
+
+**Caching Strategy**:
+```
+Level 1: Cache common tag combinations
+- Store frequently occurring 5-tag patterns
+- Reduce computation for similar properties
+
+Level 2: Cache visual embeddings
+- Store image feature vectors
+- Enable rapid similarity matching
+
+Level 3: Cache regional preferences
+- Dubai properties favor certain views
+- Mumbai properties have different style preferences
+```
+
+**Batch Processing**:
+```
+Single image: ~3 seconds target
+Batch of 10: ~15 seconds (1.5s per image with optimization)
+Batch of 50: ~60 seconds (1.2s per image with heavy caching)
+```
+
+### A/B Testing Metrics
+
+**Track These KPIs**:
+- Tag accuracy vs. human expert assessment (target: >92%)
+- Search relevance improvement (click-through rate increase)
+- Listing view duration (engagement indicator)
+- Buyer inquiry rate correlation with tag quality
+- False positive rate by category (<8% target)
+
+### Regional Customization
+
+**Dubai Market**:
+- Emphasize landmark views (Burj Khalifa, Palm, Marina)
+- Luxury indicators highly valued
+- Modern/contemporary style dominant
+
+**Mumbai Market**:
+- Sea views premium
+- Compact space optimization
+- Traditional + modern blend common
+
+**Singapore Market**:
+- Sky gardens, greenery views
+- Smart home features
+- Efficient space utilization
+
+**London Market**:
+- Period features in older properties
+- Ceiling height important
+- Natural light premium
+
+**NYC Market**:
+- City views, skyline
+- Pre-war vs. modern distinction
+- Loft-style in certain neighborhoods
