+## Bugfix: Archive Notification Message
+
+### Issue
+Odoo core has a bug in the archive notification where the parameters are swapped, showing an illogical message like:
+> "Of the 20,000 records selected, only the first 50,000 have been archived/unarchived."
+
+This is impossible since you cannot archive more records than were selected.
+
+### Root Cause
+**Location**: `odoo/addons/web/static/src/legacy/js/views/list/list_controller.js:658-659`
+
+**Bug**: The sprintf parameters are in the wrong order:
+```javascript
+const msg = _.str.sprintf(
+    _t("Of the %d records selected, only the first %d have been archived/unarchived."),
+    total, resIds.length  // ← WRONG ORDER
+);
+```
+
+### Fix
+This module patches the `ListController._toggleArchiveState` method to swap the parameters:
+```javascript
+const msg = _.str.sprintf(
+    _t("Of the %d records selected, only the first %d have been archived/unarchived."),
+    resIds.length, total  // ← CORRECT ORDER  
+);
+```
+
+### Result
+After the fix, the notification correctly shows:
+> "Of the 50,000 records selected, only the first 20,000 have been archived/unarchived."
+
+### References

+- Fixed in: `spp_base_common/static/src/legacy/js/views/list/list_controller_fix.js`
