The card consumed the API directly via useVerifyMfa() (TanStack Query
mutation). Per Decision F's intent (store owns business logic, the
component consumes typed results), the card now calls
useAuthStore.verifyMfa() and pattern-matches on the MfaVerifyResult
discriminated union.
Changes:
- MfaChallengeCard: drop useVerifyMfa import; call authStore.verifyMfa
with camelCase args (sessionToken, trustDevice, deviceFingerprint,
deviceName); local isVerifying ref replaces verifyMutation.isPending.
On result.kind === 'authenticated' emit `verified` (no payload —
the store has already refreshed user state); on 'failed' surface
result.reason with a generic fallback.
- emit signature: `verified: [data: unknown]` → `verified: []`.
- login.vue: onMfaVerified no longer calls authStore.refreshUser —
authStore.verifyMfa() refreshes internally. Page just routes to
resolvePostLoginTarget().
Adds 4 vitest specs in components/auth/__tests__/MfaChallengeCard.spec.ts
covering: success path emits `verified` with camelCase args, failure
path shows reason and suppresses emit, trustDevice toggle honours
fingerprint + device name, fallback message when reason is empty.
Test count 209 → 213. Lint + typecheck clean.
