P1 of MC code-quality plan (see PLAN.md / PR-api-client.md):
- src/lib/api-client.ts (+120) ApiError + apiFetch<T> wrapper
- src/lib/__tests__/api-client.test.ts (+108) 8 vitest cases (200/401/403/500/network/loop/204/no-redirect)
- src/components/auth-expired-listener.tsx (+30) global mc:auth-expired -> /login redirect
- src/app/layout.tsx (+2) register listener
- eslint.config.mjs (+31) no-restricted-syntax warn for bare fetch('/api/...')
Quality gates passed:
- pnpm vitest run src/lib/__tests__/api-client.test.ts: 8/8 (2.5s)
- pnpm typecheck: 0 error
- pnpm lint: 0 error, 343 warn (~baseline 334 bare fetch + 9 pre-existing)
Out of scope: migrating existing 334 bare fetch sites (P2, separate PR).
P0 verification: playwright captured 19/19 /api/* returning 200 after login,
ruling out backend issue (cookie expired) — see p0-network-evidence.txt.
- Replace loadData() Promise.all 4x fetch → apiFetch<UsageStats|TrendData|...>
- Replace loadSessionCosts() fetch → apiFetch<{ sessions: SessionCostEntry[] }>
- Replace exportData() fetch → apiFetch<Response>({ raw: true })
- Add apiFetch import from '@/lib/api-client'
- Zero new errors: typecheck pass, lint 0 error

apiFetchhandles 401 redirect, 403/5xx typed errors, and network failures uniformly — preventing the exact cost-tracker freeze incident.Closes: task-11 P2.1
