Code Review

This pull request delivers a substantial set of fixes for critical and high-priority bugs, significantly improving the application's security and stability. The changes correctly address issues such as an invalid AI model name, insecure API key handling, and incorrect business logic. The detailed bug analysis report is a great addition. My review focuses on an inconsistency in the report's summary and, more importantly, the fact that the test suite is not being run. It is critical to ensure all tests pass to validate these important fixes before merging.

[gemini-code-assist]

The report indicates that the test suite is not being executed due to a pending configuration. While the logic has been verified through code review, it is crucial that the automated tests pass to confirm that the bug fixes are effective and have not introduced regressions. Please resolve the configuration issue and ensure the test suite runs successfully before this pull request is merged.

[gemini-code-assist]

This table, along with the heading on line 164, claims that 100% of high-priority bugs are fixed. However, BUG-NEW-009 is later described as 'PARTIALLY FIXED' (line 363). This is contradictory and can be misleading. Please update the summary to accurately reflect that one of the high-priority bugs was only partially addressed. For example, you could adjust the 'Fixed' count or add a note about partial fixes.
