Code Review

This pull request adds integration tests to test/integration-test.sh for keyword searching (including case-insensitivity and misses) and cross-project global learnings. The feedback suggests replacing a fragile grep assertion on JSON output with a robust Python-based JSON parser assertion to prevent failures from formatting changes.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.
For more details on the timeline and next steps, please review the Help Documentation.

Using grep to assert JSON structure (like checking for "_source": "global") is fragile because it is sensitive to whitespace, key ordering, and formatting changes (e.g., if the JSON serializer configuration changes to omit spaces around colons).

Since Python is already used in other test assertions in this file, it is more robust to parse the output as JSON and assert the field value directly.
