Reasoning

component from path globs (test-coverage); effort from diff stats (1029+0 LOC, 6 files); LLM: Adds new test coverage for the serverStatus command, covering behavior, output, syntax, and error cases — a functional enhancement to the test suite.

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.

[Major] wiredTiger assertions violate the "no engine-specific implementation details" rule. TEST_COVERAGE.md:65 is explicit: "Don't test internal storage details (wiredTiger, engine-specific fields, etc.). These belong in engine-specific test suites, not compatibility tests." Three cases assert the wiredTiger section directly:

• wiredTiger_is_object (response_structure) — asserts wiredTiger exists as an object
• exclude_wiredTiger (field_toggle) — asserts it can be excluded
