Abstract

fetched live from OpenAlex

Reasoning about the correctness of a replication algorithm is a difficult endeavor. If correctness has to be shown for a component based architecture where a client request can lead to execution across different components or tiers, this is even more difficult. Existing formalisms are either restricted to systems with only one component, or make strong assumptions about the setup of the system. In this paper, we present a flexible framework to reason about exactly-once execution in a failure-prone replicated component based system. Our approach allows us to reason about the execution across the entire system, e.g., application server and database tier. If a given replication algorithm makes assumptions about some of the components, then those can be easily integrated into the reasoning process.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
