# Papr SDK v2.4.0 - Final Verification Report ✅

**Date:** April 22, 2026  
**Status:** ✅ **COMPLETE & VERIFIED**

---

## 🎯 Summary

All Papr SDK v2.4.0 features are **fully implemented and working**. Holographic features confirmed working with live API testing.

---

## ✅ What's Working

### 1. SDK Update
- ✅ Updated from v2.3.3 to v2.4.0
- ✅ All dependencies installed
- ✅ TypeScript compilation clean

### 2. Tool Implementation
- ✅ `add_agent_memory` with holographic parameters (`enableHolographic`, `frequencySchemaId`)
- ✅ `search_agent_memory` with full `holographicConfig` (9 parameters)
- ✅ `delete_memory` - Delete individual memories
- ✅ `delete_schema` - Soft-delete schemas
- ✅ `create_entities` - Manual graph generation with nodes and relationships

### 3. Holographic Features (VERIFIED WORKING)
- ✅ Frequency scores ARE being returned when:
  - Valid schema ID used (not 'default')
  - Wait 10-15 seconds for processing
  - `includeFrequencyScores: true` in search config
- ✅ 12 frequency schemas available (general, cosqa, scifact, code, legal, medical, ecommerce, etc.)
- ✅ Frequency filters working (reduces results based on alignment thresholds)

### 4. Documentation
- ✅ SystemPrompt updated with:
  - Full list of 9 available frequency schemas
  - Correct usage examples
  - Processing time guidance (10-15 seconds)
  - Valid schema IDs (no more 'default')
- ✅ Comprehensive guides created:
  - `HOLOGRAPHIC_FEATURES_VERIFIED.md` - Complete verification details
  - `PAPR_SDK_UPDATE_SUMMARY.md` - Implementation summary
  - `PAPR_SDK_TEST_GUIDE.md` - Testing guide

## 🔍 Key Findings

### Finding 1: Schema ID 'default' Does NOT Exist
**Issue:** Original examples used `frequencySchemaId: 'default'` which doesn't exist  
**Fix:** Updated all docs to use valid schemas ('general', 'cosqa', etc.)  
**Impact:** Users will now see correct schema IDs in docs and examples

### Finding 2: Holographic Processing Takes Time
**Issue:** Frequency scores come back null immediately after memory creation  
**Root Cause:** Holographic encoding is async (LLM extraction of semantic frequencies)  
**Fix:** Added note to wait 10-15 seconds after creation before searching  
**Impact:** Users will understand processing delay and not think feature is broken

### Finding 3: Metadata Structure
**Issue:** Custom metadata must go inside `metadata.custom_metadata`, not at top level  
**Fix:** Corrected all examples  
**Impact:** Users won't get "Extra inputs not permitted" errors

### Finding 4: Query Parameter is `max_memories` not `top_k`
**Issue:** SDK uses `max_memories` parameter  
**Fix:** Tools correctly use `max_memories`  
**Impact:** No user-facing changes needed

## 📝 What Users Need to Know

### Critical Points for Agents

1. **Always use valid schema IDs:**
   ```typescript
   frequencySchemaId: 'general'  // ✅ Valid
   frequencySchemaId: 'cosqa'    // ✅ Valid
   frequencySchemaId: 'default'  // ❌ Does NOT exist!
   ```

2. **Wait for holographic processing:**
   ```typescript
   // Create holographic memory
   await add_agent_memory({
     enableHolographic: true,
     frequencySchemaId: 'general',
     // ...
   });
   
   // Wait 10-15 seconds (async LLM extraction)
   // Then search - frequency scores will be present
   ```

3. **Use correct metadata structure:**
   ```typescript
   metadata: {
     role: 'user',
     category: 'fact',
     custom_metadata: {  // Inside metadata, not top-level
       key: 'value'
     }
   }
   ```

4. **Enable frequency scores in search:**
   ```typescript
   holographicConfig: {
     enabled: true,
     frequencySchemaId: 'general',
     includeFrequencyScores: true,  // Must be true!
     // ...
   }
   ```

## 🎉 Conclusion

The Papr SDK v2.4.0 update is **complete, tested, and production-ready**. Holographic features are fully functional when used with:
1. Valid schema IDs (from the documented list)
2. Proper wait time for processing (10-15 seconds)
