Restore test: injected HTTP 500 after write-back
注入した障害
Injected fault: after write-back starts changing the site, the test server returns HTTP 500 for site pages, so the check after write-back fails.

補足
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.
