Abstract
Total ordering is a messaging guarantee increasingly required of content-based pub/sub systems, which are traditionally focused on performance. The main challenge is the uniform ordering of streams of publications from multiple publishers within an overlay broker network to be delivered to multiple subscribers. Our solution integrates total ordering into the pub/sub logic instead of offloading it as an external service. We show that our solution is fully distributed and relies only on local broker knowledge and overlay links. We can identify and isolate specific publications and subscribers where synchronization is required: the overhead is therefore contained to the affected subscribers. Our solution remains safe under the presence of failure, where we show total order to be impossible to maintain. Our experiments demonstrate that our solution scales with the number of subscriptions and has limited overhead for the non-conflicting cases. A holistic comparison with group communication systems is offered to evaluate their relative scalability.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
