The field validated, shipped in the CRD, and reached no controller. The world PVC survives deletion unconditionally -- it is a StatefulSet VolumeClaimTemplate, StatefulSet deletion does not cascade to template PVCs, and no finalizer exists anywhere in the operator. So setting it true described what already happened, and setting it false did nothing at all. False is the worse half: it reads as a request to delete a world, and was silently ignored. This departs from spec v4.1 §5, which asks for "删除:finalizer 清 Service/STS/ConfigMap,PVC 按 retainOnDelete". Neither half was ever built. Restoring that line means adding a finalizer whose other listed duties -- Service, StatefulSet, ConfigMap -- ownerReference GC already performs, so the only work it would newly do is delete worlds, on a path that does not pass the reaper's verified-backup check. The reaper is the one thing in the system allowed to destroy a world and it earns that by proving a backup first. A second door without that check is not an improvement. The spec is a frozen versioned document, so it is left alone and the departure is recorded in troubleshooting.md §13, beside the behaviour it explains. §12 loses its inert row and its opening sentence, which existed to introduce this one field: every field in that table is now read by a controller. Deployed installs need nothing. A CR still carrying retainOnDelete keeps working, because a v1 CRD prunes unknown keys on the next write and the behaviour the field claimed to control was never conditional. go build, go vet and go test ./... pass on Linux with zero failures; the CRD still parses and storage keeps size and storageClassName.
