Code Review Summary

This PR is well-structured and addresses the issue appropriately. The changes significantly simplify the codebase by delegating model downloads to LemonadeClient.ensure_model_downloaded() instead of maintaining complex subprocess logic with retry-on-corruption handling.

🟢 Strengths

1. Significant code reduction (~165 lines removed) by delegating to LemonadeClient.ensure_model_downloaded() which already handles local and remote scenarios

2. Smart auto-detection of remote mode from LEMONADE_BASE_URL (init_command.py:160-171) - parses the URL and detects non-localhost hostnames

3. Bug fix for _ctx_warning (init_command.py:1327) - correctly uses truthiness check instead of hasattr() which was always true

4. Comprehensive test coverage - 5 new test classes covering:

   • Remote URL detection (TestRemoteAutoDetection)
   • Model download delegation (TestDownloadModels)
   • Edge cases (localhost, 127.0.0.1, ::1, explicit flag override)

5. Documentation improvements - Clear tabs for Local vs Remote mode in docs/reference/cli.mdx

🟡 Minor Observations

1. init_command.py:1321-1334 - The hasattr(self, "_ctx_verified") check on line 1321 has the same potential issue that was fixed for _ctx_warning. Both attributes are initialized to None in __init__() (lines 196-197), so hasattr() will always return True. However, the logic here is slightly different since it explicitly checks truthiness on line 1322 (if self._ctx_verified:), so this works correctly. Consider making the pattern consistent by removing the outer hasattr() check entirely:

   # Current (works but hasattr is redundant):
   if hasattr(self, "_ctx_verified"):
       if self._ctx_verified:
           ...
   
   # Could simplify to:
   if self._ctx_verified:
       ...

2. IPv6 localhost detection - The code correctly handles ::1 but doesn't handle other IPv6 loopback representations like [::1] with brackets. This is a very minor edge case unlikely to occur in practice.

3. _find_lemonade_server() is now unused in remote mode - The method at init_command.py:725-785 is still used for local mode server startup, but might be worth noting in a comment that it's only relevant for local mode.

🟢 Test Quality

The new tests are well-structured and properly mock dependencies:

• Uses @patch.dict("os.environ", ...) for environment variable testing
• Tests both positive and negative cases for URL parsing
• Validates that ensure_model_downloaded() is called for both local and remote modes
• Tests --force-models flow with delete + re-download

Verdict

LGTM - This is a clean refactor that improves maintainability while fixing the reported issue. The minor observations above are non-blocking and can be addressed in future iterations if desired.
