When completed rows all agree, an existing coverage mechanism certifies that agreement despite arbitrary temporary differences. A global specialization removes name-length restrictions and supports immediate reuse. Two final answer profiles remain the next discovery problem.
A second proof that even binary palindromes have a finite scaffolding automaton, built from immutable typed receipts and a whole-client normalization theorem. Its explicit source-model bounds remain under review.
The transfer theorem from strict real-time multitape computation to parsing expression grammars. Persistent two-stack tape zippers turn each machine step into one bounded scaffold update, with the construction checked in Lean 4.
A resource audit and parameter retuning of the direct deterministic reduction from 3SAT to Euclidean closest vector. It reaches 1/30-hardness and isolates a 1/28 frontier for the retained proof architecture.
A study of scaffold histories as mathematical objects: what they build, what a bounded observer can distinguish, and which local rewrites connect behaviorally equivalent histories. Develops causal presentations, guarded folding, sewing, and feedback.
Lifts the algebra of unary scaffold histories from moves to relations among moves. Corrected order-ideal lattices, CAT(0) cube complexes, and a bounded list of critical cells provide a coherent higher-dimensional presentation.
