Confidence: 0.85 (mixed)

Reasoning

component from path globs (test-coverage); effort from diff stats (3039+48 LOC, 12 files); LLM: Adds new query and write test cases for bulkWrite operations, expanding test coverage for an existing feature area.

If a label is wrong, remove it manually and ping @patty-chow so the rules can be tuned. The bot will not re-label items that already have component labels.
