3 more textbooks (Russell PoM + Laplace + Dedekind): 54 -> 62/92 (67%)
Three PD / CC-BY-SA-4.0 primary substrates ingested under fox
"keep filling maths in" directive:
Russell - Principles of Mathematics 1903 (Klement HTML, 1MB
single page, 546 chunks). CC-BY-SA-4.0 typesetting + PD content.
Pillar I/II — class theory, relations, Russell's Paradox
derivation that IMP 1919 omits.
Laplace - A Philosophical Essay on Probabilities (PG #58881 HTML,
Truscott-Emory 1902 English, 111 chunks). PD by age. Pillar V
primary; pre-Kolmogorov foundational treatise.
Dedekind - Essays on the Theory of Numbers (PG #21016 TeX, Beman
1901 English, 57 chunks via existing textbook_tex pipeline).
PD by age. Pillar III primary alongside Peano; Dedekind cuts
+ chains-and-induction definition of natural numbers.
Plus 5 new citation-alias rows per #000041 (decision_by="fox 2026-05-10"):
Mendelson -> Russell PoM (+2 pillar I)
Enderton -> Russell PoM (+1 pillar I)
Jech -> Russell PoM (+4 pillar II — Russell's Paradox)
Landau -> Dedekind (cascade miss; 0 lift)
Kolmogorov -> Laplace (+1 pillar V)
Per-pillar:
I: 7/13 -> 10/13 (+3)
II: 5/10 -> 9/10 (+4 — pillar II nearly clear)
III: 7/13 stable
IV: 18/18 stable
V: 0/5 -> 1/5 (+1)
VI: 3/5 stable
VII: 9/14 stable
IX: 5/14 stable

Cumulative day-of-2026-05-10 lift: 18 -> 62 (+44 records, +47pp absolute).
30 records still stuck. Top-yield next candidates:
- Hilbert-Ackermann 1928 for pillar I formal proof axioms
- Whitehead-Russell PM Vol I for pillar II type-theoretic Russell's Paradox resolution
- Software Foundations / Wadler Programming Language Foundations
in Agda (both CC-BY-4.0) for pillar IX lambda calculus
- Pillar III cascade tuning (Peano + Dedekind shards have content
but FTS5 token cascade misses symbolic axioms)
