 ```
 
-The dump contains the three allowlisted `vectors` tables, their data and ACLs, plus the
-`public.tht_vector_migrations` ledger. Login roles and passwords are deliberately not copied:
-provision/reconcile the approved role names on the target first, and install the `vector`
-extension in its `vectors` schema. The target must otherwise contain no vector tables or ledger.
+The script resolves exactly one Docker volume with the labels
+`com.docker.compose.project=<project>` and `com.docker.compose.volume=qdrant-data`, stops the
+`qdrant` service if it is running, archives that volume's persistent contents, then restores the
+prior service state. It never performs global Docker cleanup and refuses to overwrite an existing
+archive path.
 
-Restore always names both the currently active source and a target on a physically distinct
-PostgreSQL cluster. The script compares PostgreSQL system identity, so host aliases or a different
-database in the active cluster cannot bypass the guard. It refuses a non-empty target unless
-`--force-nonempty` is explicit, and the clean restore is one transaction:
+Restore targets that same exact project-scoped `qdrant-data` volume. Because restore replaces the
+persistent Qdrant data in place, it requires an explicit confirmation that exactly repeats the
+Compose project name:
 
 ```sh
 ./scripts/vector-restore.sh \
-  --active-host vector-db --active-database thoth --active-user thoth_backup \
-  --active-password-file /secure/thoth/vector-active-password \
-  --target-host vector-db-restore --target-database thoth --target-user thoth_restore \

+  --project-name thothii \
+  --input /secure/backups/thoth-qdrant-2026-08-08.tar \
+  --confirm-project thothii
 ```
 
-After restore, run `tht vector migrate --status --json`, adapter health, and a known retrieval
-query against the target before changing any migration/export endpoint.
+The restore script stops `qdrant`, validates the exact labeled target, stages the current volume
+contents for rollback, extracts the requested archive into the volume, and then returns the
+service to its prior running state. After restore, run the backend health checks and a known
+retrieval query before reopening write traffic.
