Four real surfaces wired to tenant-registry (settings, settings/api-keys CRUD, audit pagination, products live entitlements), five forward-looking empty states with CTAs. 56 vitest tests + 10 Playwright canaries. lib/format.ts consolidates date helpers.

10 route shells under /[slug]/, role-filtered Nav, backstage stub at /__backstage__, dashboard reads session.products to render tiles. src/lib/session.ts is the canonical role × surface matrix; canSee() is the only RBAC primitive in the portal (real enforcement remains at the API layer). 24 vitest tests; 100% src/lib coverage.
