Abstract
Safety-critical systems often require safety certification before their deployment. It has become common for the safety argument to be documented in an assurance case, and in many domains assurance cases are recommended or required for certification. However, the rapidly increasing complexity and scale of safety-critical systems is making it increasingly difficult to produce rigorous and convincing assurance cases. Recent work on the Workflow+ framework has presented an opportunity to make more rigorous assurance cases while also coping with the complexity of modern systems. To do this, principles for the derivation of safety case argumentation based on safety analysis and development processes modelled in Workflow+ must be developed. These principles will allow for arguments to be constructed systematically and potentially semi-automatically. This work outlines the approach for my research aiming to develop these principles, a method to systematically construct argumentation based on these principles and to automate the construction of argumentation where possible.

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.
