Does AI Help? October 2026, version 2026.10.9

Presentation-only patch: BibTeX uses 12-character repository commit IDs. Full hashes remain in canonical evidence records, CSL-JSON and RIS; document SHA-256 checksums are preserved. Includes the web citation page and back-to-top navigation. Findings, source counts and the 13 October 2026 cutoff are unchanged. Earlier snapshots remain immutable.
