Restore test: write-back reaches its time limit
注入的故障
Injected fault: the test server delays its replies to write-back steps, and the write-back time limit is set lower than in production, so the limit is reached after changes to the site start.

缺口與修在哪一版
結果不是「Matches snapshot」，或注入的故障生效卻判修好的跑次，都在這裡：改了什麼、修在哪一版、重跑的日期與結果。

補充
Runs from the acceptance testing of version 2.1.460 on 2026-11-12, on the small test site. Before each case, two problems were planted on the test site so that the case reaches write-back; the first table shows the HTTP status after that step. Payment in these runs is simulated; the recovery fee column shows the refund the system recorded for that payment.
這些是我們測試主機上、某一版、某一天的紀錄，不是對任何網站結果的承諾；其他主機、PHP 與 WordPress 版本的結果可能不同。
