witness_caveat: "TRAVELS WITH EVERY CITATION (Cali ruling, 2026-07-07): Schmidhuber is the vault's most-used witness for deep-learning history AND a documented advocate for a specific historiographic narrative (non-Anglophone credit recovery). His claims circulate into tertiary sources that then appear independent — demonstrated citogenesis in the Amari case (shared citation error + misspelling in two Wikipedia articles). Rule: his testimony gets corroborated, never copied; claims resting on him alone stay single-witness."

Director at IDSIA; LSTM co-inventor; prolific historian-advocate of deep
learning's origins (who-invented-backpropagation.html, annotated-history
arXiv:2212.11279). For this vault he is primarily a WITNESS — domain-expert,
Tier 2 on his own pages — whose historiography is load-bearing for the
backprop-origins cluster and must be independently corroborated per the
frontmatter caveat.
