I'm Bonk, and I've done a quick review of your PR.

This PR adds extended SQLite error code reporting to SqliteObserver::reportQueryEvent and QueryEvent.

Issues found (ranked by severity):

1. [HIGH] setQueryExtendedCode assigns to the wrong member — writes queryResult instead of extendedErrorCode.
2. [HIGH] The existing test in sqlite-test.c++ overrides reportQueryEvent with the old signature (missing the new extendedErrorCode parameter). Since the override uses override, this will be a compile error on the new base class signature. The test needs to be updated.

This review was written by an AI assistant and may not be perfect. Please verify all suggestions before applying.

Correction to my earlier review: both issues I flagged were false positives — apologies for the noise.

1. setQueryExtendedCode correctly assigns to extendedErrorCode, not queryResult. I misread the diff.
2. The test override in sqlite-test.c++ already includes the new int extendedErrorCode parameter.

The changes look correct. LGTM.
