+## Verification Commands
+
+Run these to verify the installation:
+
+```bash
+# Test all 11 adaptors
+for target in claude gemini openai markdown langchain llama-index haystack weaviate chroma faiss qdrant; do
+    echo "Testing $target..."
+    skill-seekers package output/skill --target $target --no-open
+done
+
+# Test new CLI features
+skill-seekers quality output/skill --report --threshold 5.0
+skill-seekers multilang output/skill --detect
+skill-seekers update output/skill --check-changes
+skill-seekers stream output/skill
+skill-seekers stream large_file.md
+
+# Run test suite
+pytest tests/test_adaptors/ tests/test_rag_chunker.py \
+       tests/test_streaming_ingestion.py tests/test_incremental_updates.py \
+       tests/test_multilang_support.py tests/test_quality_metrics.py -q
+```
+
+---
+
+## Known Limitations
+
+1. **MCP Server:** Requires proper initialization (expected behavior)
+2. **Streaming:** File streaming converts to generator format (working as designed)
+3. **Quality Check:** Interactive prompt in package command requires 'y' input
+
+---
+
+## Conclusion
+
+✅ **All features working**  
+✅ **All integrations connected**  
+✅ **All tests passing**  
+✅ **Production ready**
+
+The `feature/universal-infrastructure-strategy` branch is **ready for merge to main**.

+# Final QA Verification Report
+
+**Date:** February 7, 2026  
+**Branch:** `feature/universal-infrastructure-strategy`  
+**Status:** ✅ **PRODUCTION READY**
+
+---
+
+## Summary
+
+All critical CLI bugs have been fixed. The branch is now production-ready.
+
+---
+
+## Issues Fixed
+
+### Issue #1: quality CLI - Missing --threshold Argument ✅ FIXED
+
+**Problem:** `main.py` passed `--threshold` to `quality_metrics.py`, but the argument wasn't defined.
+
+**Fix:** Added `--threshold` argument to `quality_metrics.py`:
+```python
+parser.add_argument("--threshold", type=float, default=7.0, 
+                    help="Quality threshold (0-10)")
+```
+
+**Verification:**
+```bash
+$ skill-seekers quality output/skill --threshold 5.0
+✅ PASS
+```
+
+---
+
+### Issue #2: multilang CLI - Missing detect_languages() Method ✅ FIXED
+
+**Problem:** `multilang_support.py` called `manager.detect_languages()`, but the method didn't exist.
+
+**Fix:** Replaced with existing `get_languages()` method:
+```python
+# Before: detected = manager.detect_languages()
+# After:
+languages = manager.get_languages()
+for lang in languages:
+    count = manager.get_document_count(lang)
+```
+
+**Verification:**
+```bash
+$ skill-seekers multilang output/skill --detect
+🌍 Detected languages: en
+   en: 4 documents
+✅ PASS
+```
+
+---
+
+### Issue #3: stream CLI - Missing stream_file() Method ✅ FIXED
+
+**Problem:** `streaming_ingest.py` called `ingester.stream_file()`, but the method didn't exist.
+
+**Fix:** Implemented file streaming using existing `chunk_document()` method:
+```python
+if input_path.is_dir():
+    chunks = ingester.stream_skill_directory(input_path, callback=on_progress)
+else:
+    # Stream single file
+    content = input_path.read_text(encoding="utf-8")
+    metadata = {"source": input_path.stem, "file": input_path.name}
+    file_chunks = ingester.chunk_document(content, metadata)
+    # Convert to generator format...
+```
+
+**Verification:**
+```bash
+$ skill-seekers stream output/skill
+✅ Processed 15 total chunks
+✅ PASS
+
+$ skill-seekers stream large_file.md
+✅ Processed 8 total chunks
+✅ PASS
+```
+
+---
+
+### Issue #4: Haystack Missing from Package Choices ✅ FIXED
+
+**Problem:** `package_skill.py` didn't include "haystack" in `--target` choices.
+
+**Fix:** Added "haystack" to choices list:
+```python
+choices=["claude", "gemini", "openai", "markdown", "langchain", 
+         "llama-index", "haystack", "weaviate", "chroma", "faiss", "qdrant"]
+```
+
+**Verification:**
+```bash
+$ skill-seekers package output/skill --target haystack
+✅ Haystack documents packaged successfully!
+✅ PASS
+```
+
+---
+
+## Test Results
+
+### Unit Tests
+```
+241 tests passed, 8 skipped
+- 164 adaptor tests
+- 77 feature tests
+```
+
+### CLI Integration Tests
+```
+11/11 tests passed (100%)
+
+✅ skill-seekers quality --threshold 5.0
