- Dashboard layout resolves tenanciesModuleByPort server-side (one isTenanciesModuleEnabled call per port the user has access to) and passes the map through AppShell → Sidebar. Atomic SSR — no flicker of the nav entry in/out after hydration. - Sidebar gains NavItemGated.requiresTenanciesModule. The Tenancies entry (KeyRound icon, immediately below Berths) only renders when the currently-active port has the flag flipped on. Per-port live switch fires when the rep toggles ports without reload. - /[portSlug]/tenancies + /[portSlug]/tenancies/[id] both call isTenanciesModuleEnabled and notFound() when disabled — guards against direct URL access even when the sidebar is hidden. - API routes (/api/v1/tenancies, /[id], /berths/[id]/tenancies) prepended with assertTenanciesModuleEnabled — matches design § "All routes ... return 404 when off". NotFoundError maps to 404. - Existing tenancy API tests get a makePortWithTenancies() helper (calls enableTenanciesModule after makePort) so the gate is satisfied. Affects 2 test files (16 tests retargeted). Verified: tsc clean, 1493/1493 vitest. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
