 Integrated all community reviews through Follow-up 70 of [discussion #4](https://huggingface.co/datasets/ulamai/UnsolvedMath/discussions/4) (`2026-10-16`) and expanded the corpus with major mathematician open-problem collections:
 - **Complete Erdős Problems (`EP-1`–`EP-1221`)**: Added all 589 missing Erdős problems, bringing `erdos_problems` to all 1,221 canonical problems from `erdosproblems.com` / `teorth/erdosproblems`, repaired all 581 corrupted `EP-*` background headers, and expanded bibliography citation keys into full bibliographic references.
-- **Complete Kourovka Notebook (`KOU-1.1`–`KOU-21.150`, 1,934 problems)**: Expanded `kourovka_new_problems_21` from 150 problems (Issue 21) to all 1,934 problems across Issues 1–21 (1965–2026) and the Archive of Solved Problems from `arXiv:1401.0300v48` (Oct 7, 2026), integrating editor-confirmed solutions (`*` / `\zv`) as `solved` (`evidence="maintained_source"` or `"published"`) and flagging unverified AI solution claims (`\sharp` / `\ai`) with `status_review.evidence = "unrefereed_claim"`.
+- **Complete Kourovka Notebook (`KOU-1.1`–`KOU-21.150`, 1,934 problems)**: Expanded `kourovka_new_problems_21` from 150 problems (Issue 21) to all 1,934 problems across Issues 1–21 (1965–2026) and the Archive of Solved Problems (Khukhro & Mazurov, eds., Oct 2026 revision), integrating editor-confirmed solutions (`*` / `\zv`) as `solved` (`evidence="maintained_source"` or `"published"`) and flagging unverified AI solution claims (`\sharp` / `\ai`) with `status_review.evidence = "unrefereed_claim"`.
 - **44 New Mathematician Open-Problem Collections (`AMR-113`–`AMR-156`, 1,200 deduplicated problems)**: Extracted, macro-expanded, quality-filtered, and deduplicated 1,200 problems from 43 pure-LaTeX arXiv open-problem surveys/notebooks (including the Lyapin Semigroup Notebook, Hirzebruch's Problem List updates, Beauville's Holomorphic Symplectic Geometry, Buzzard–Fornæss–Krantz's Several Complex Variables Problem List, Navas's ICM 1-Manifolds list, Pak's ICM Enumerative Combinatorics list, Propp's Matching & Trimer Lists, Lusztig's Iwahori–Hecke Algebras, Brenti's Coxeter Unimodality, Arithmetic Dynamics, O'Donnell's Analysis of Boolean Functions, Naber's Lower Ricci Curvature, Tsaban's Selection Principles, Sokal's Lattice Gases/Potts Models, Dinew–Guedj–Zeriahi's Pluripotential Theory, Pandharipande's AGNES list, Burns–Matveev's Geodesics, Barmpalias et al.'s Mathematical Logic, Berger–Bedford's Hénon Maps, Elayavalli's Ultraproduct $\mathrm{II}_1$ Factors, etc.) plus all 28 problems from Richard Stanley's *Positivity Problems and Conjectures in Algebraic Combinatorics* with full literature status updates.
 - **Strict `status="solved"` Policy**: `status="solved"` (2,287 published records) is reserved strictly for peer-reviewed publications (`status_review.evidence = "published"`, 1,533 records) or canonical community-verified trackers (`status_review.evidence = "maintained_source"`, 754 records). All unrefereed preprints, AI proof claims (`SOLVED-BY-YOU` / Kourovka `\sharp`), and unverified deductions are classified under `partially_solved` or `open` with `status_review.evidence = "unrefereed_claim"` (541 published records).
 - **Statement Recovery & Quarantine**: Promoted verified clean statements across OWR and AIM, upgraded 480+ OCR/Unicode-damaged AIM/AMR statements from source-verified blockquotes in `research_results.json`, and archived (`published=false` with `archive_reason`) unrecoverable extracts, context-only/invalid statements, truncated fragments, multi-problem PDF dumps, and non-mathematical workshop admin/biology items.
