Does the unread body text of Werbos (1988), pp. 350-355, mention Isaacs, Bellman, Pontryagin, Kelley, or Bryson?
claim-werbos-1988-reference-list-names-no-isaacs-bellman-pontryagin-kelley-or-bryson rests on Werbos's bibliography, which names none of them, but the capture read only about lines 1-743 of the 1,209-line extracted text plus the bibliography. A body-text mention (author named without a reference-list entry) in pp. 350-355 is not ruled out.
What would answer this: read lines 744-1099 of the cached extraction cache/sources/1c5be985e963f74a566ad05951c82aa5f9fe83ec55d920e865da0dbc6e4d0ad9.txt (same source as claim-werbos-1988-rhw-special-case-of-dynamic-feedback) and search for those names. Cheap, local, no fetch needed.
Progress 2026-09-26: manual read of pp. 350-355 found none of the five names — see claim-werbos-1988-body-pp-350-355-names-no-isaacs-bellman-pontryagin-kelley-or-bryson. Left open only because no mechanical grep receipt exists (OCR text, manual read); a string search over the cached extract would close it.
Not for this question: Werbos's 1988 ICNN "Backpropagation: Past and future," a likelier place for a lineage statement, is a separate lead.
