Network Admin → Ultimate Multisite → Sites (grid view, All Sites tab) rendered a bulk-delete checkbox on pending-site cards whose value is the membership ID. That tab submits the regular site delete bulk action, so Base_List_Table::process_bulk_action() called wu_get_site($membership_id)->delete() and wp_delete_site() removed an unrelated live site whose blog ID matched the membership ID (tables and uploads dropped).
This was observed in production: selecting leftover pending test signups deleted three unrelated customer sites.
Fix
views/base/sites/grid-item.php: render the pending-card checkbox only in the dedicated Pending view (type=pending), where the action is delete-pending and membership IDs are expected. This mirrors the existing guard in Site_List_Table::column_cb() for the list view. Other views show a spacer; Publish and the per-card actions are unchanged.
tests/WP_Ultimo/List_Tables/Site_List_Table_Test.php: grid regressions for All Sites (type=all), no type, and the Pending view.
Verification
New grid tests fail on the previous template (2 failures) and pass with the fix.
Pending sites no longer display a bulk-action checkbox in the All Sites view or when no site type is selected. The checkbox remains available in the Pending view and uses the correct membership ID.
Pending-site cards now show a bulk-delete checkbox only in the Pending view. Tests cover the All Sites view, an unset type filter, and the Pending view.
The grid template renders a pending-site bulk-delete checkbox only when the requested type is pending. Tests verify that other views omit the checkbox and that the Pending view uses membership ID 9.
Pending-site cards no longer offer a bulk-delete checkbox outside the Pending view, which fixes the reported accidental selection. Server-side bulk delete still accepts IDs without checking where they came from. An admin with a stale page open, or a crafted request, could delete an unrelated live site whose ID matches a membership ID. Consider adding validation to the bulk-delete action before merging, as the linked issue requests.

Explanation
The PR changes two files: views/base/sites/grid-item.php and tests/WP_Ultimo/List_Tables/Site_List_Table_Test.php. The template change limits the pending-card checkbox to the Pending view. This directly addresses the bug in #2028. The test additions cover the same grid rendering behavior and support that fix. The indentation change inside the label block and the added PHP comment are cosmetic and tied to the same change. No unrelated file or behavior change appears in the PR summary or in the two inspected diffs.
Full details: Linked Issues check
Explanation
Issue #2028 has two coding parts. (1) Primary fix: pending-site cards must not submit membership IDs to the regular site delete action. The PR meets this. views/base/sites/grid-item.php renders the pending bulk-delete checkbox (name="bulk-delete[]", value=membership ID) only when wu_request('type') === 'pending'. Other views render a spacer. This mirrors Site_List_Table::column_cb(). Publish and per-card actions are unchanged. Three new grid tests in tests/WP_Ultimo/List_Tables/Site_List_Table_Test.php cover type=all, no type, and type=pending. The tests assert the absence of the checkbox in All Sites and no-type views and its presence with value 9 in the Pending view. (2) Defense in depth: the issue Fix section asks for refusal or validation in Base_List_Table::process_bulk_action() or site bulk delete, so that IDs from views listing pending items are not treated as blog IDs. The PR does not change inc/list-tables/class-base-list-table.php. At the reviewed head, the 'delete' case in process_bulk_action() still passes each submitted ID to the model getter and delete call without a view or ID check (the file read was truncated after this point, so later code is unverified). The PR description also does not claim this hardening. Part (2) is therefore an unmet coding requirement of #2028.
Resolution
Add the defense-in-depth check that issue #2028 requests. In Base_List_Table::process_bulk_action() (or the site bulk delete path), refuse or validate submitted IDs for the regular 'delete' action when the request comes from a view that lists pending items with membership-ID values. Validation can confirm that each submitted ID is a real blog ID shown in that view. Add a regression test that submits a membership ID through the regular site delete action and asserts that no wp_blogs row is deleted.

Validate site bulk-delete IDs at the action boundary.
A stale All Sites form can still submit a pending membership ID. Base_List_Table::process_bulk_action() resolves model=site through wu_get_site() and calls delete() for the regular delete action. A colliding ID can therefore call wp_delete_site() for an unrelated live site. Reject or validate these IDs before regular site deletion.
