It was the number of result declarations, which is
different from the number of results when one
result declaration declares more than one
variable, as in `x, y int`.
A deferred Close runs at function exit, but the CFG splices it in at the exit node where it can be reached along paths that never execute Sync. The previous dominance check therefore produced a false positive when a statement followed the if-block that registered the defer (e.g. deferredCloseWithSync2). For deferred closes, require instead that a handled Sync post-dominates the point where the defer is registered, which guarantees Sync runs before Close on every path on which Close is registered. Non-deferred closes keep the existing dominance check.
Correct the doc for unhandledCall (it also matches expression statements where the result is discarded) and remove a stale commented-out line in isWritableFileHandle.
There are paths to the exit of the function which go through the defer
statement and paths which don't, so we add an optional call to the
deferred function. This causes FPs in the query as it stands.
Changes based on code review:
1. Remove redundant strings.Contains check in isExactTestPackage
The equality check on the next line handles both cases, making
the early return unnecessary.
2. Extract package selection logic into selectBestPackages function
This reduces code duplication and allows the test to call the
actual implementation rather than copying the logic.
3. Add TestSelectBestPackages to test the new function
Comprehensive test covering single packages, test vs production,
exact vs nested tests, and multiple packages.

This test verifies that root internal test files (package foo, not
foo_test) are correctly extracted when the repository has both:
1. Root-level internal tests (main_test.go with package main)
2. Nested packages with tests (nested/nested_test.go)
This scenario reproduces the bug that was fixed: the old extractor
would select the wrong package variant and miss root internal test
files.
The test ensures:
- main_test.go (root internal test) is extracted
- nested/nested_test.go (nested test) is extracted
- All test functions from both files are present in the database
This prevents regression of the bug fix.
