+- [x] pyasn integration for ASN lookup
+- [x] Graceful fallback when database files missing
+- [x] Country codes displayed in test output: `(US)`, `(IN)`, etc.

-### [ ] 16. Geographic Validation
-Verify proxy actually routes through claimed location using IP geolocation.
+### [x] 16. Geographic Validation
 
-### [ ] 17. HTTPS/SSL Proxy Testing
-Add capability to test HTTPS CONNECT proxies.
+**Completed.** Added IP2Location and pyasn for proxy geolocation.
+- requirements.txt: Added IP2Location package
+- proxywatchd.py: IP2Location for country lookup, pyasn for ASN lookup
+- proxywatchd.py: Fixed ValueError handling when database files missing
+- data/: IP2LOCATION-LITE-DB1.BIN (2.7M), ipasn.dat (23M)
+- Output shows country codes: `http://1.2.3.4:8080 (US)` or `(IN)`, `(DE)`, etc.

 - Warns on missing source_file, unknown engines
 - Errors on unwritable database directories
 - Integrated into ppf.py, proxywatchd.py, scraper.py main entry points
+
+### [x] Profiling Support
+- config.py: Added --profile CLI argument
+- ppf.py: Refactored main logic into main() function
+- ppf.py: cProfile wrapper with stats output to profile.stats
+- Prints top 20 functions by cumulative time on exit
+- Usage: `python2 ppf.py --profile`
+
+### [x] SIGTERM Graceful Shutdown
+- ppf.py: Added signal handler converting SIGTERM to KeyboardInterrupt
+- Ensures profile stats are written before container exit
+- Allows clean thread shutdown in containerized environments
+- Podman stop now triggers proper cleanup instead of SIGKILL
+
+### [x] Unicode Exception Handling (Python 2)
+- Problem: `repr(e)` on exceptions with unicode content caused encoding errors
+- Files affected: ppf.py, scraper.py (3 exception handlers)
+- Solution: Check `isinstance(err_msg, unicode)` then encode with 'backslashreplace'
+- Pattern applied:
+  ```python
+  try:
+      err_msg = repr(e)
+      if isinstance(err_msg, unicode):
+          err_msg = err_msg.encode('ascii', 'backslashreplace')
+  except:
+      err_msg = type(e).__name__
+  ```
+- Handles Korean/CJK characters in search queries without crashing
