Phase 05 Plan 11: Admin Hard-Delete with Password Confirmation Summary

Admin users can now permanently delete non-admin user accounts with Argon2 password verification — wrong or missing password returns 403 without touching any data; correct password triggers the existing SEC-09 cloud/MinIO purge pipeline.

Tasks Completed

Task	Name	Commits	Files
1 (RED)	Failing tests for delete_user password verification	8727592	backend/tests/test_admin_api.py
1 (GREEN)	UserDeleteConfirm model + password verification	390a693	backend/api/admin.py
2	adminDeleteUser API + inline delete confirmation panel	7268721	frontend/src/api/client.js, frontend/src/components/admin/AdminUsersTab.vue

What Was Built

Backend (admin.py):

• UserDeleteConfirm Pydantic model with admin_password: str field added to the Request models section
• verify_password imported from services.auth (alongside existing hash_password, revoke_all_refresh_tokens)
• delete_user handler signature updated to accept body: UserDeleteConfirm
• Fail-fast password check placed before any DB reads for the target user — 403 "Invalid admin password" on failure
• All existing SEC-09 cloud credential purge, MinIO object cleanup, and audit log logic is unchanged

Frontend (client.js):

• adminDeleteUser(id, adminPassword) exported — calls DELETE /api/admin/users/{id} with { admin_password } JSON body

Frontend (AdminUsersTab.vue):

• Added state: confirmDelete, deletePassword, deleteError
• Added functions: startDelete, cancelDelete, confirmDoDelete
• startDeactivate updated to clear delete panel when deactivate panel opens (mutual exclusion)
• Delete button added to active user row (after Deactivate) and deactivated user row (after Reactivate)
• Inline password confirmation panel: warning text, password input with Enter shortcut, error display, "Delete permanently" / Cancel buttons with loading spinner

Verification

• pytest test_admin_api.py::test_delete_user_correct_password — PASSED (204, user removed from list)
• pytest test_admin_api.py::test_delete_user_wrong_password — PASSED (403, user survives)
• pytest test_admin_api.py::test_delete_user_no_body — PASSED (422, Pydantic validation)
• Full test_admin_api.py suite — 21/21 PASSED
• npm run build — zero errors, built in 689ms

Deviations from Plan

Minor Filename Discrepancy (auto-handled)

Found during: Task 1 Issue: Plan references backend/tests/test_admin.py but the actual file is backend/tests/test_admin_api.py Fix: Tests added to backend/tests/test_admin_api.py (the existing correct file) Impact: None — tests run and pass correctly

TDD Gate Compliance

• RED gate: commit 8727592 — test(05-11): add failing tests for delete_user password verification
• GREEN gate: commit 390a693 — feat(05-11): add UserDeleteConfirm model + admin password verification in delete_user
• 2/2 tests failed in RED phase (correct_password passed because old endpoint had no auth check; wrong_password and no_body failed correctly)

Threat Surface Scan

No new network endpoints introduced. The DELETE /api/admin/users/{id} endpoint existed before this plan. Changes add a body requirement (reducing attack surface — anonymous DELETE calls now return 422 instead of 204). No new trust boundaries.

Known Stubs

None — adminDeleteUser wired directly to the backend endpoint; delete panel uses live API with real error propagation.

Self-Check: PASSED

• backend/api/admin.py — modified, contains UserDeleteConfirm and verify_password check
• frontend/src/api/client.js — modified, exports adminDeleteUser
• frontend/src/components/admin/AdminUsersTab.vue — modified, contains delete panel
• backend/tests/test_admin_api.py — modified, contains 3 new tests
• Commits 8727592, 390a693, 7268721 — all present in git log
