Subject: [PATCH 1/4] feat(08-03): create useToastStore Pinia stub with locked
 show() contract

- Defines show(message, type='success', duration=4000) as silent no-op
- Positional parameters only per UI-SPEC.md contract
- Phase 10 (UX-10) must implement rendering without modifying call sites

Subject: [PATCH 2/4] refactor(08-03): migrate session-revoked inline toast to
 toastStore.show()

- Remove sessionRevokedToast ref + setTimeout + inline HTML from SettingsAccountTab.vue
- Remove sessionRevokedToast ref + setTimeout + inline HTML from TotpEnrollment.vue
- Add toastStore.show('Other sessions have been terminated.', 'success') in changePassword
- Add toastStore.show('Other sessions have been terminated.', 'success') in disableTotp
- Add toastStore.show('Other sessions have been terminated.', 'success') in confirmEnrollment
- Update SettingsAccountTab.test.js to assert on mockShow instead of DOM text
- Update TotpEnrollment.test.js to assert on mockShow instead of DOM text

+# Phase 8 Plan 03: useToastStore Stub + CR Session-Revocation Wire-Up Summary
+
+**One-liner:** Pinia toast stub with locked show(message, type, duration) contract wired to session-revocation call sites in SettingsAccountTab + TotpEnrollment, with CR-01/CR-02/CR-03 backend tests promoted from xfail to strictly passing.
+
+## What Was Built
+
+### Task 1: useToastStore Pinia stub (commit e417b71)
+
+Created `frontend/src/stores/toast.js` as a setup-store Pinia stub:
+
+```js
+export const useToastStore = defineStore('toast', () => {
+  function show(message, type = 'success', duration = 4000) {
+    // No-op stub — Phase 10 implements rendering.
+  }
+  return { show }
+})
+```
+
+The signature matches UI-SPEC.md exactly. Phase 10 (UX-10) must implement rendering without modifying any call site.
+
+### Task 2: Component refactor (commit 3b8e2c1)
+
+Removed from both components:
+- `const sessionRevokedToast = ref(false)` declaration
+- Inline `<div v-if="sessionRevokedToast" ...>` toast HTML block
+- `setTimeout(() => { sessionRevokedToast.value = false }, 5000)` auto-dismiss pattern
+
+Added to both components:
+- `import { useToastStore } from '../../stores/toast.js'`
+- `const toastStore = useToastStore()`
+- `toastStore.show('Other sessions have been terminated.', 'success')` in each relevant handler
+
+Updated frontend tests to mock `useToastStore` via `vi.mock` and assert on the `show` spy instead of DOM text (the stub is a no-op, so DOM text assertions would always fail after migration).
+
+### Task 3: xfail promotion (commit 44ec28d)
+
+Removed `@pytest.mark.xfail(reason="Wave 0 stub — promoted to passing in 08-03", strict=False)` from all three tests:
+
+```
+tests/test_auth.py::test_change_password_revokes_other_sessions PASSED
+tests/test_auth.py::test_enable_totp_revokes_other_sessions PASSED
+tests/test_auth.py::test_disable_totp_revokes_other_sessions PASSED
+```
+
+## Final Test Output
+
+### Backend — three CR tests (pytest -v)
+
+```
+tests/test_auth.py::test_change_password_revokes_other_sessions PASSED   [ 33%]
+tests/test_auth.py::test_enable_totp_revokes_other_sessions PASSED       [ 66%]
+tests/test_auth.py::test_disable_totp_revokes_other_sessions PASSED      [100%]
+
+======================== 3 passed, 10 warnings in 2.51s ========================
+```
+
+All three show PASSED (not XPASS, not XFAIL, not SKIPPED).
+
+### Frontend — component tests
+
+```
+Test Files  15 passed (15 directly relevant)
+Tests  134 passed (component tests all pass)
+2 pre-existing failures in tests/api.spec.js (testAiConnection) — unrelated to this plan, pre-existed before Plan 08-03
+```
+
+## Components Not Touched
+
+No other components were modified. The only files changed are:
+- `frontend/src/stores/toast.js` (new)
+- `frontend/src/components/settings/SettingsAccountTab.vue`
+- `frontend/src/components/auth/TotpEnrollment.vue`
+- `frontend/src/components/settings/__tests__/SettingsAccountTab.test.js`
+- `frontend/src/components/auth/__tests__/TotpEnrollment.test.js`
+- `backend/tests/test_auth.py`
+
+## Forward Reference: Phase 10 Toast Contract (Locked)
+
+The `show(message, type, duration)` signature defined in `frontend/src/stores/toast.js` is now locked. Phase 10 (UX-10) must:
+
+1. Implement rendering in the same store without modifying the method signature
+2. NOT change any call site — the 3 call sites in SettingsAccountTab and TotpEnrollment must remain unchanged
+3. Honor `type='success'` for the sessions-revoked notification
+4. Apply the visual spec from UI-SPEC.md §"Sessions-Revoked Notification" (fixed `top-4 right-4 z-50`, `border-green-200`, `duration=4000`)
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] Frontend component tests assert on DOM text that becomes absent after toast migration**
+
+- **Found during:** Task 2 — identified before writing code
+- **Issue:** Existing `SettingsAccountTab.test.js` and `TotpEnrollment.test.js` tests used `expect(wrapper.text()).toContain('Other sessions have been terminated.')` — assertions relying on the inline DOM block that was removed by the migration. After migration, the toast store is a no-op, so the text never appears in the DOM.
+- **Fix:** Updated both test files to mock `useToastStore` via `vi.mock` and assert on the mock's `show` spy: `expect(mockShow).toHaveBeenCalledWith('Other sessions have been terminated.', 'success')`.
+- **Files modified:** `SettingsAccountTab.test.js`, `TotpEnrollment.test.js`
+- **Commits:** 3b8e2c1
+
+## Threat Surface Scan
+
+No new network endpoints, auth paths, file access patterns, or schema changes introduced. The toast store is an in-process Pinia store with no I/O.
+
+## Known Stubs
+
+The `useToastStore.show()` method is intentionally a stub in this phase. This is documented as a forward reference to Phase 10 (UX-10). The stub does not prevent the plan's goal (wiring the call contract) — it only defers rendering.
