lung-nodule-followup: agent input data
Development copy of the agent-visible input of the Terminal-Bench Science task lung-nodule-followup, hosted here
while the task is under review. Before merge it is mirrored to harborframework/terminal-bench-science-lfs under the
same prefix, and this copy is then deleted or made private.
Contents. lung-nodule-followup/input/case_XX.tar.gz, one archive per case (10 archives, 1.0 GB). Each
extracts to case_XX/{baseline,followup}/IMG####.dcm: the baseline and first annual low-dose chest CT of one
participant of the National Lung Screening Trial; 20 series and 3,308 DICOM files (1.7 GB) in total. The files are
archived because downloading 3,308 files one by one exceeds the Hub's request limit during an image build.
Pixel data are unchanged. Headers were de-identified with a whitelist: new UIDs, case ids as patient ids, synthetic
dates one year apart, no private tags. The task image checks every extracted file against data_checksums.sha256
in the task repository. No answers or grading data are stored here.
Revisions. 2026-10-16: first release (commit ea0cce0). 2026-10-25: three cases (case_06, case_09, case_10)
replaced by three other NLST participants; the other seven archives hold the same files as before.
