Abstract
Failure independent path-protecting (FIPP) p-cycles are an extension of the basic p-cycle concept which retains the property of pre-cross-connection of protection paths while acheiving end-to-end failure-independent path protection switching against either span or node failures. An issue with the current method of shared-backup path protection (SBPP) in a transparent optical network is that spare channels for the backup path must be cross-connected on-the-fly upon failure. It takes extra time and signaling to make the required cross-connections but, more importantly, until all connections are made it is not actually known if the backup optical path has adequate transmission integrity. Thus, pre-failure certainty about optical path integrity is an important reason to have backup paths fully pre-connected before failure. FIPP p-cycles support the same failure-independent, end-node activated switching of SBPP but with fully pre-connected protection paths. FIPP p-cycles may therefore be especially attractive for transparent optical networks. FIPP p-cycle network designs also exhibit capacity efficiency that is characteristic of path-oriented schemes. We think it is the only scheme known with these very high efficiencies, failure independence, and the property of fully pre-cross-connected protection paths.

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
