 ## Integrated Through
 
-- Rollback/correction task `20260903-backup-revert-extension-update-c71a4e92` preserved the complete former `0.5.167`/migration-019 stack at remote branch `codex/backup-extension-update-20260903-b2e33e2`, removed the central private-OSS/ECS automatic-update service architecture without rewriting history, and retained the exact Chrome extension `0.5.167` source/package on the active main line with migration 018.
+- Correction commit `fe1cc2cddc29e4dead81e53c16d31bb71493602d` from integration task `20260903-backup-revert-extension-update-c71a4e92` preserved the complete former `0.5.167`/migration-019 stack at remote branch `codex/backup-extension-update-20260903-b2e33e2`, removed the central private-OSS/ECS automatic-update service architecture without rewriting history, and retained the exact Chrome extension `0.5.167` source/package on the active main line with migration 018.
 - Merge commit `3224758` and integration task `20260903-finalize-extension-update-a6c4e192` remain historical records of the full-stack extension-update design. Only the plugin `0.5.167` release, adaptive entry readiness, and dormant plugin-side idle/reload safeguards remain active; the server orchestration is preserved on the backup branch only.
 - Commit `c4c469f4441d744627af2d34abe693b6783e833c` for the independently advanced remote deployment/extension line.
 - Commit `cd45ce17d0fcd25f7fa89ab9f8a391d3e904ecdf` for WeChat attachment correlation and privacy-safe server diagnostics.
