Read the Portal's tool_access claim (JWT + /api/oauth/account) into NousToolAccessInfo and gate managed Tool Gateway access on it: tool_gateway_entitled (paid OR live pool) and per-category tool_gateway_entitled_for(). The pool funds web/image/tts/browser but not video, so per-backend availability, the charge picker (ensure_nous_portal_access coverage_category), and managed defaults all respect coverage.
Setup: rebuild prompt_enable_tool_gateway as a per-tool checklist that renders whenever the pool is enabled, lists only pool-covered tools (video excluded for free-pool users), and is framed as the free tool pool for $0 subscribers rather than a paid subscription. get_gateway_eligible_tools now gates and filters off the entitlement snapshot.
