Deployment Regression compares captures from the same owned-build HTTP and UI fixtures; changed bytes alone are not a regression. Cache Coherence checks read-only local CacheStorage and compares unverified release markers; it does not probe CDN freshness. Cross-origin isolation observes actual browser capability flags without claiming security conformance. Cookie policy inspection reviews supplied Set-Cookie declarations locally without reading the cookie store. Security-header inspection reviews supplied declarations locally, without a security score or upload. Resource waterfall inspects retained timings or a local redacted capture. Asset integrity compares listed public files with their generated build manifest. Connection speed measures application goodput. Upload responsiveness compares response time while a bounded transfer competes. Location comparisons require controlled repeat runs. WebSocket resilience checks heartbeat echoes across a continuous socket or one deliberate clean reconnect. SSE stability validates an event sequence continuously or across one planned application-stream interruption. JWT inspection decodes and optionally verifies supplied tokens locally, without an upload. The developer inspector checks our own signed HTTP response; it is not an arbitrary-URL API client.

Only implemented capabilities are linked here. Planned DNS, TLS, CORS, authentication and application-failure tools are not advertised as runnable utilities. Several capabilities intentionally share an existing test view.
