---

### 6. mainServiceGeneration (GenerationService Class)
**Calls Out:**
- `get_renderer()` → renderers.registry (line 501)
- Utility functions from subDocumentUtility
- Uses modelRegistry (external)

**Called By:**
- subCoreAi.callAiDocuments (calls renderReport)

---

### 9. subSharedAiUtils
**Functions Provided:**
- `buildPromptWithPlaceholders()`
- `sanitizePromptContent()` 
- `extractTextFromContentParts()`
- `reduceText()`
- `determineCallType()`

**Called By:**
- subCoreAi (imports and calls functions)
- subDocumentGeneration (via services.ai.sanitizePromptContent)
- subPromptBuilderExtraction (via services.ai.sanitizePromptContent)

---

### 10. subJsonSchema
**Functions Provided:**
- `get_document_subJsonSchema()`
- `get_multi_document_subJsonSchema()`

**Called By:**
- subPromptBuilderExtraction.buildExtractionPrompt (line 172)

---

## Circular Dependencies

**AI Service Loop:**
1. subDocumentProcessing → subCoreAi.readImage() (for image processing)
2. subDocumentProcessing → mainServiceExtraction (for extraction)
3. mainServiceExtraction → subPipeline (for processing)
4. subPipeline creates IntelligentTokenAwareMerger

**Flow:**
```
subDocumentProcessing.extractContent()
  → mainServiceExtraction.extractContent()
    → subPipeline.runExtraction()
      → returns ContentExtracted
        → processed by subDocumentProcessing
          → calls subPipeline._applyMerging()
```
