Investigate a volume-to-surface projection anomaly
The supplied source is a real snapshot of a published neuroimaging analysis library. In one volume-to-surface workflow, a volumetric product distributed with an anatomical lookup table is mapped onto a cortical surface. The command completes, but some finite surface values cannot be associated with any row of that table.
Treat this as a scientific reproduction investigation rather than a textual patch task. Inspect the source and the public reproduction, reproduce the anomaly, and determine why the projected result is incompatible with the accompanying scientific metadata. Repair the public volume-to-surface workflow so that the result can be used in the downstream analysis while other documented uses remain compatible.
The repair should generalize beyond the supplied example and should not be specialized to one volume, surface, or lookup table. Preserve the library's documented behavior for other supported inputs and geometries.
Do not hard-code the public volume, table entries, mesh, sample count, affine, or
expected output. Do not modify reproduce.py, the fixtures, or the evaluation
harness. Work inside the supplied source snapshot and keep the task runnable
without network access.
Run the public workflow with:
python reproduce.py
The initial snapshot is expected to report the observed scientific anomaly.
After your repair it should report post_fix_success. Generated files belong
under outputs/.
