Abstract
Leakage Risk Assessment of CO 2 Transportation by Pipeline at the Illinois Basin Decatur Project, Decatur, Illinois 4 th Quarter FY2011 Milestone: Report on pipeline CO 2 leakage risk assessment Alberto Mazzoldi and Curtis M. Oldenburg Earth Sciences Division Lawrence Berkeley National Laboratory, Berkeley, CA October 19, 2011 Revised February 26, 2013 Acknowledgment: This work was carried out as part of the Midwest Geologic Sequestration Consortium Phase III Illinois Basin Decatur Project (IBDP) funded by the Assistant Secretary for Fossil Energy, Office of Sequestration, Hydrogen, and Clean Coal Fuels, National Energy Technology Laboratory. Additional support came from Lawrence Berkeley National Laboratory through the U.S. Department of Energy under Contract No. DE-AC02-05CH11231. We thank David Picard and P.G. Sriram (Clearstone Engineering Ltd., Calgary) for providing pipe outflow modeling results, and. Andrea Borgia (LBNL) for helpful internal review comments. Rev. 1.1

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
