      "--disk-reclaim-policy: On create, controls deletion behavior: `delete` (default) or `retain`. The current update reference does not document this flag.",
      "--disk-source-snapshot: Snapshot name used as the source for the home disk. Update documentation lists it as an alternative to the disk size/type pair.",
      "--disk-size` + `--disk-type` / `--disk-source-snapshot: Update syntax presents the size/type pair and source-snapshot flag as alternatives; do not specify both alternatives together.",
      "Docs conflict: Release note says `--disk-reclaim-policy` was added to `gcloud workstations configs update`; the current official update reference does not list or describe that flag, so its update usage and behavior are unverified."
