-**Problem:** No easy way to export working proxies for use elsewhere.
-
-**Implementation:**
-```python
-# new file: export.py
-def export_proxies(proxydb, format='txt', filters=None):
-    """Export working proxies to various formats."""
-
-    query = 'SELECT proto, proxy FROM proxylist WHERE failed=0'
-    if filters:
-        if 'proto' in filters:
-            query += ' AND proto=?'
-
-    rows = proxydb.execute(query).fetchall()
-
-    if format == 'txt':
-        return '\n'.join('%s://%s' % (r[0], r[1]) for r in rows)
-    elif format == 'json':
-        import json
-        return json.dumps([{'proto': r[0], 'address': r[1]} for r in rows])
-    elif format == 'csv':
-        return 'proto,address\n' + '\n'.join('%s,%s' % r for r in rows)

-# CLI: python export.py --format json --proto socks5 > proxies.json

-**Files:** new export.py
-**Effort:** Low
-**Risk:** Low
+**Completed.** Added export.py CLI tool for exporting working proxies.
+- Formats: txt (default), json, csv, len (length-prefixed)
+- Filters: --proto, --country, --anonymity, --max-latency
+- Options: --sort (latency, added, tested, success), --limit, --pretty
+- Output: stdout or --output file
+- Usage: `python export.py --proto http --country US --sort latency --limit 100`

+- Tor pool health: per-host latency, success rate, availability
+- Failure categories: timeout, proxy, ssl, closed, etc.
+- proxywatchd.py: get_runtime_stats() method provides stats callback
