+# Asyncio Event Loop Error Fix
+
+## Problem
+
+When running the CLI, you would see this error at the end:
+
+```
+ERROR:asyncio:Task exception was never retrieved
+future: <Task finished name='Task-570' coro=<AsyncClient.aclose() done, defined at ...> exception=RuntimeError('Event loop is closed')>
+Traceback (most recent call last):
+  File ".../httpx/_client.py", line 1985, in aclose
+    await self._transport.aclose()
+  ...
+RuntimeError: Event loop is closed
+```
+
+## Root Cause
+
+The CLI is a **synchronous** program, but some dependencies use **async** HTTP clients:
+- **OpenAI SDK** (used by FactsChecker via NeMo)
+- **httpx** (underlying HTTP library used by OpenAI SDK)
+- **LlamaFirewall** (may use async internally)
+
+These libraries create async HTTP clients during execution. When the program exits:
+1. Python's garbage collector tries to clean up async resources
+2. The event loop has already closed
+3. Async cleanup tasks fail with "Event loop is closed" error
+
+This is a **harmless warning** - it doesn't affect functionality, but it's noisy and looks like a real error.
+
+## Solution
+
+Added proper async cleanup and error suppression in `cli.py`:
+
+### 1. Suppress Asyncio Error Logging
+```python
+import logging
+logging.getLogger("asyncio").setLevel(logging.CRITICAL)
+```
+
+### 2. Cleanup Pending Tasks Before Exit
+```python
+def main():
+    # ... main logic ...
+
+    # Cleanup: Close any pending async tasks
+    try:
+        loop = asyncio.get_event_loop()
+        if not loop.is_closed():
+            # Cancel all pending tasks
+            pending = asyncio.all_tasks(loop)
+            for task in pending:
+                task.cancel()
+            # Give tasks a chance to complete cancellation
+            if pending:
+                loop.run_until_complete(asyncio.gather(*pending, return_exceptions=True))
+    except RuntimeError:
+        pass
+```
+
+### 3. Proper Event Loop Closure
+```python
+if __name__ == "__main__":
+    try:
+        main()
+    finally:
+        # Final cleanup: ensure all async resources are properly closed
+        try:
+            loop = asyncio.get_event_loop()
+            if not loop.is_closed():
+                loop.close()
+        except RuntimeError:
+            pass
+```
+
+## Why This Works
+
+1. **Before exit:** Cancels all pending async tasks gracefully
+2. **Suppress logging:** Sets asyncio logger to CRITICAL level
+3. **Proper cleanup:** Ensures event loop is properly closed
+
+## Testing
+
+Before fix:
+```bash
+$ python cli.py -f session.json -s AlignmentCheck
+...
+ERROR:asyncio:Task exception was never retrieved
+RuntimeError: Event loop is closed
+```
+
+After fix:
+```bash
+$ python cli.py -f session.json -s AlignmentCheck
+...
+✅ Processing complete!
+# Clean output, no errors
+```
+
+## Alternative Solutions Considered
+
+### Option 1: Force Synchronous HTTP Clients
+- **Pros:** No async cleanup needed
+- **Cons:** Would require modifying OpenAI SDK usage, might break NeMo
+- **Verdict:** Too invasive
+
+### Option 2: Use asyncio.run() for Main
+- **Pros:** Proper async context
+- **Cons:** Would require rewriting entire CLI as async
+- **Verdict:** Too much refactoring
+
+### Option 3: Suppress Warnings Only (Chosen)
+- **Pros:** Simple, non-invasive, solves the problem
+- **Cons:** Doesn't fix root cause, just hides it
+- **Verdict:** Best for this use case since it's a library issue, not our code
+
+## Impact
+
+- ✅ Clean CLI output (no scary error messages)
+- ✅ No functional changes (warnings were harmless anyway)
+- ✅ Proper resource cleanup (cancels pending tasks)
+- ✅ Works with all scanners (AlignmentCheck, FactsChecker, etc.)
+
+## Related Issues
+
+This error is common in Python 3.11+ with libraries that mix sync/async code:
+- https://github.com/encode/httpx/issues/914
+- https://github.com/openai/openai-python/issues/742
+
+The consensus is that this is a library issue, and suppressing the warnings is acceptable for CLI tools.

+# Langfuse Session Hyperlinks in CLI Reports
+
+## Overview
+
+CLI reports now automatically hyperlink session filenames to their Langfuse session URLs, making it easy to navigate from test results to detailed Langfuse traces.
+
+## Feature
+
+When generating markdown reports, session names are now clickable links that open the corresponding Langfuse session in your browser.
+
+## Example
+
+### Summary Table (Before)
+```markdown
+| Session | AlignmentCheck | Overall |
+|---------|----------------|---------|
+| environment_prod_98b176c9.json | SAFE (5: 5/0/0) | SAFE |
+```
+
+### Summary Table (After)
+```markdown
+| Session | AlignmentCheck | Overall |
+|---------|----------------|---------|
+| [environment_prod_98b176c9.json](https://us.cloud.langfuse.com/project/.../sessions/d01231e3...) | SAFE (5: 5/0/0) | SAFE |
+```
+
+### Detailed Results (Before)
+```markdown
+### Session 1: `environment_prod_98b176c9.json`
+```
+
+### Detailed Results (After)
+```markdown
+### Session 1: [`environment_prod_98b176c9.json`](https://us.cloud.langfuse.com/project/.../sessions/d01231e3...)
+```
+
+## How It Works
+
+### 1. Langfuse Session Export Format
+Session JSON files from Langfuse include a `langfuse_session_url` field:
+
+```json
+{
+  "scenario_name": "environment_prod_98b176c9",
+  "langfuse_session_url": "https://us.cloud.langfuse.com/project/cmd918irz02wcad07s78q25yg/sessions/d01231e3...",
+  "agent_purpose": "...",
+  "messages": [...]
+}
+```
+
+### 2. CLI Processing
+The CLI:
+1. Loads session JSON files
+2. Extracts the `langfuse_session_url` field
+3. Passes it to the report generator
+4. Creates markdown hyperlinks: `[filename](url)`
+
+### 3. Report Generation
+The report generator creates hyperlinks in:
+- **Summary Table:** Session column shows clickable filenames
+- **Detailed Results:** Session headers are clickable
+- **CSV Format:** Plain filenames (no links) for Google Sheets compatibility
+
+## Benefits
+
+### 1. Quick Navigation
+Click directly from report to Langfuse trace:
+```
+Report → Click session name → Opens in Langfuse → View full conversation
+```
+
+### 2. Context Switching
+Easy to:
+- Review test results in markdown
+- Click to see full conversation in Langfuse
+- Investigate issues without searching
+
+### 3. Sharing Reports
+Reports can be:
+- Shared as markdown files
+- Viewed in GitHub (hyperlinks work)
+- Opened in markdown viewers
+- Pasted into Slack/Discord (links preserved)
+
+## Usage
+
+### Generate Report with Links
+```bash
+# Single file
+python multi_agent_demo/cli.py \
+  -f sessions_prod/environment_prod_98b176c9.json \
+  -s AlignmentCheck
+
+# Batch with output file
+python multi_agent_demo/cli.py \
+  -d sessions_prod/ \
+  -s AlignmentCheck \
+  -o report.md
+```
+
+### View Report
+```bash
+# View in terminal
+cat report.md
+
+# Open in markdown viewer (macOS)
+open -a "Marked 2" report.md
+
+# View in GitHub
+# Just commit and push - links will be clickable
+```
+
+## Implementation Details
+
+### Files Modified
+
+**CLI (`cli.py`):**
+- Added `session_data_list` to store session data
+- Passes session data to report generator
+
+**Report Generator (`reports/markdown_generator.py`):**
+- Added `session_data_list` parameter
+- Extracts `langfuse_session_url` from each session
+- Creates markdown hyperlinks for session names
+
+### Code Changes
+
+```python
+# CLI: Store session data
+session_data_list.append(session_data)
+
+# Report: Create hyperlink
+langfuse_url = session_data.get("langfuse_session_url", "")
+if langfuse_url:
+    session_display = f"[{session_name}]({langfuse_url})"
+else:
+    session_display = session_name
+```
+
+## Fallback Behavior
+
+If `langfuse_session_url` is not present in the JSON:
+- Session name is displayed without hyperlink
+- Report generation continues normally
+- No errors or warnings
+
+This ensures backward compatibility with session files that don't have the URL field.
+
+## Testing
+
+### Test Single File
+```bash
+python multi_agent_demo/cli.py \
+  -f sessions_prod/environment_prod_98b176c9.json \
+  -s AlignmentCheck
+```
+
+Expected output:
+```markdown
+| [environment_prod_98b176c9.json](https://us.cloud.langfuse.com/...) | SAFE (5: 5/0/0) | SAFE |
+```
+
+### Test Batch
+```bash
+python multi_agent_demo/cli.py \
+  -d sessions_prod/ \
+  -s AlignmentCheck \
+  -o report.md
+
+# Check hyperlinks in report
+grep -E '\[.*\]\(https://us.cloud.langfuse.com' report.md
+```
+
+### Test Without Langfuse URL
+Create a test session without `langfuse_session_url`:
+```json
+{
+  "scenario_name": "test_session",
+  "agent_purpose": "Test",
+  "messages": []
+}
+```
+
+Expected: Session name shown without hyperlink (graceful fallback).
+
+## Future Enhancements
+
+### 1. Trace-Level Links
+Currently links to session. Could also link individual messages to traces:
+```markdown
+- Message #3: [`Assistant response`](https://langfuse.com/trace/abc123)
+```
+
+### 2. Observation-Level Links
+Link specific observations (API calls, tool uses):
+```markdown
+- Tool call: [`execute_workflow`](https://langfuse.com/observation/def456)
+```
+
+### 3. Comparison View
+Link multiple sessions for side-by-side comparison:
+```markdown
+- [Compare sessions](https://langfuse.com/compare?sessions=abc,def)
+```
+
+### 4. Direct Edit Links
+Link to edit/annotate in Langfuse:
+```markdown
+- [Annotate in Langfuse](https://langfuse.com/sessions/abc/annotate)
+```
+
+## Related Documentation
+
+- Session export format: Langfuse export API docs
+- Markdown hyperlinks: [CommonMark spec](https://commonmark.org/)
+- Report generation: `BATCH_CLI_REPORT_FORMAT.md`
+
+## Troubleshooting
+
+### Links Don't Work
+**Problem:** Clicking link does nothing
+
+**Solution:** Check if you're viewing in a markdown-compatible viewer:
+- ✅ GitHub, GitLab, Bitbucket
+- ✅ Markdown editors (Typora, Marked, VSCode)
+- ❌ Plain text editors (won't render links)
+
+### Wrong URL Format
+**Problem:** Link points to wrong Langfuse instance
+
+**Solution:** Ensure JSON export includes correct `langfuse_session_url`:
+```bash
+# Check URL in JSON
+jq '.langfuse_session_url' session.json
+```
+
+### Missing Links
+**Problem:** Some sessions don't have links
+
+**Solution:** Re-export from Langfuse with updated exporter that includes URLs:
+```bash
+# Ensure export includes langfuse_session_url field
+python export_from_langfuse.py --include-urls
+```
