correctness: Add null-guard to TrackingController listener notification #4
Issues found
Score: 25/100
This PR adds a null-guard (if (l != null)) inside the applyEditNoStack listener notification loop. However, the existing code already has an identical null-guard at line 143 in the same file (visible in the full source): if (l != null) l.onTrackChanged(updated);. The diff appears to be re-adding a guard that already exists, which suggests the AI worker hallucinated a bug or failed to read the current file state. This is a no-op tautological change — the if (l != null) check is already present. The PR should be rejected as it adds nothing but diff noise. No test changes accompany the diff, and the worker did not note that the guard already exists.

[warning] Redundant null-guard already exists in source
The added `if (l != null)` guard at lines 139-141 is identical to the null-guard already present at line 143 in the current source file. The worker appears to have hallucinated a missing null check without reading the actual file contents. This diff is a no-op that only introduces formatting noise (expanding `for` loop to block form without changing semantics). The PR should be rejected.

[warning] No tests added or modified for claimed correctness fix
The PR description claims this is a 'correctness' fix, but no tests are added, modified, or even referenced. A genuine null-guard fix should include a regression test that injects a null listener and verifies no NPE is thrown. The absence of tests for a 'correctness' PR is a red flag for AI-generated slop.
