GERO public research archive: eleven joint numerical reports, October 2026

Archival compilation of eleven previously published GERO reports by Xamit Kadirbekov and Daniyal Kadirbekov. Original publication dates, source pins, authorship, limitations and upstream-status snapshots remain in each report. This compilation does not claim new experiments, peer review, acceptance of every patch, or measured customer losses.

The enclosed original evidence ZIPs were copied byte for byte and verified against the public catalogue SHA-256 values. MANIFEST.json records the source URLs and checksums. AI assisted the compilation and verification.
