27 October 2026 — Research archive translated into English
All 101 Stockback and Coinback records are now published in English at their existing addresses. Translations keep every number, table and chart from the Korean originals, which remain in the version history with their source hashes. Five embedded charts that previously showed as raw markup now render. Third-party personal names in internal folder paths were replaced with a role description.
27 October 2026 — Research archive migrated
Published 101 historical source records: 64 Stockback and 37 Coinback entries. Original source hashes, historical context and known corrections accompany each record. This migration did not rerun the old experiments or refresh consumed holdouts.
27 October 2026 — OFI article recovered
Restored the earlier OFI/NQ address from owner-provided shared conversations. The corrected edition withdraws unsupported feed-provider comparisons, throughput and immediate-production claims. A second copied header reports 21 December 2025 as the original date; the original WordPress timestamp has not been independently verified.
