ギャップと修正版
「復旧」以外で終わった実行はすべてここに記載します：変更内容、修正を含むバージョン、再実行の日付と結果。
| 発見日 | サーバー構成 | 接続方式 | 変更内容 | 修正版 | 再実行 |
|---|---|---|---|---|---|
| 2026-11-08 | nginx + PHP-FPM | SSH | The recovery stopped while some faults were still hiding others, so the case ended as not recovered. The recovery now runs more rounds before it stops. | 2.1.443 | 2026-11-10 · Recovered |

補足
Only problem types listed on the What we fix page are shown. One of them, a database table collation mismatch, could not be created on the database servers used here, so it was not introduced and is not listed. Lifting the login lockout is one of the items ticked in the Recovery Authorization Consent Form before the recovery fee is paid; it was ticked in these runs. WP admin mode was not run in this series.
