Abstract
Zipper codes, a new framework for describing spatially-coupled product-like codes, are introduced. This framework encompasses many types of codes such as staircase codes and braided block codes. New types of codes such as tiled and delayed diagonal zipper codes are also introduced. Simulation results show that these new type of codes achieve comparable performance to staircase codes while requiring less memory. This thesis also analyzes the types of stall patterns that can arise in zipper codes and how they affect the error floor. Finally, the impact of error-and-erasure decoding in zipper codes is also studied. Software simulation results show that adding erasure symbols improves the coding gain by around 0.1 dB with only a small increase in memory overhead and decoding complexity.

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
