 `ssh://git@100.71.119.27:222/monster/3GOD.git` (Gitea on the old box) can be archived once this
 copy is committed. The running VPS service is unaffected — it is deployed, not sourced live from
 that checkout. ultra's `~/Documents/3GOD` is a dev copy holding 4 files and its `:8788` is closed.

+`archive.sh` (deployed to `ultra:~/depot-backups/archive.sh` — outside `~/Documents` because
+launchd + TCC) follows the MeshGod flow: ultra rsyncs the VPS asset dir, then rclones to
+**`gdrive:DB-BACKUP/3god-depot`**. 7.5 GB / 774 assets.
+
+**Not git.** Git has no delta compression for binary blobs, so 774 GLBs would grow the Gitea repo
+without bound on every re-upload, and Gitea lives on the disk-tight old box.
+
+**Deliberate difference from the MeshGod flow: NO PRUNING.** MeshGod prunes VPS `.glb` older than
+180 days because its gallery keeps thumb+index so stale entries still list. This depot is live
+runtime infrastructure — thriftgod and procity fetch assets *by filename at runtime*, so deleting
+an old GLB breaks a shipping game with a 404. Archive only, never prune.
+
+Verify freshness the same way as the other flows:
+`rclone lsl gdrive:DB-BACKUP/3god-depot --include "*.glb" --max-age 36h`

+⚠️ Shares the whole-fleet risk noted in the backup-verify skill: the `gdrive:` remote uses
+rclone's shared Google client_id, which Google retires during 2026. When it dies every Drive flow
+breaks at once, this one included.
