A project topic like `Backend` does not match a config topic or glob such as `backend`.\n\n## Reproduction\nEvaluate GitLab project filtering with `include.topics: [\"backend\"]` and a project whose API response includes `topics: [\"Backend\"]`.\n\n## Expected\nTopic include/exclude matching should be case-insensitive and symmetric between configured topics and project topics.\n\n## Actual\nConfigured topics are lowercased, while project topics retain their original case, so mixed-case GitLab topics can fail otherwise matching filters.\n\n## Impact\nGitLab sync can unexpectedly include or exclude repositories when GitLab projects use mixed-case topics.","author":{"url":"https://github.com/DivyamTalwar","@type":"Person","name":"DivyamTalwar"},"datePublished":"2026-06-29T09:38:04.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/1388/sourcebot/issues/1388"}
