test_rejects_negative_start_line and test_rejects_negative_end_line that call
validate_source_location with start_line=0 and end_line=0 respectively,
asserting valid is False and path is None.

Greptile SummaryThis change rejects invalid source locations before extraction: non-positive start lines, reversed ranges, and non-positive end lines now return an invalid location. Direct execution confirmed malformed ranges no longer enter fallback extraction, while a valid T-Rex validation blockedThe focused source-extraction pytest module could not start because the available Python environment is missing the Confidence Score: 5/5Safe to merge based on direct execution of the changed validation boundary and preservation of valid-range behavior. The executed harness compared the parent and updated implementations, confirming that negative, zero, and reversed ranges are rejected before fallback extraction while a valid range still proceeds normally. No defects remain in the final review. Files Needing Attention: No files need further changes. The focused pytest module should be rerun in an environment with the project test dependency

Good catch on both fronts: the old truthiness check rejected zero by accident and let negative and reversed ranges straight through. One addition requested (echoing CodeRabbit's inline comment): add explicit zero-boundary cases (start_line=0 and end_line=0) to the parametrised tests, since zero rejection is now intentional behaviour rather than a falsy accident, and a future refactor to explicit comparisons should not silently change it. With that, this is merge-ready.

Addressed in commit 643092e. I consolidated the invalid range cases into a parametrized test, including explicit start_line=0 and end_line=0 cases. The focused tests and Ruff checks pass. |
