+Yoi checks method, scheme, host, optional port, and path prefix against both the manifest declaration and enablement grant before any network I/O. `http://localhost`, loopback, private, and other local targets are never ambient; they require an explicit manifest request target and an explicit matching grant. Broad targets such as `host = "*"` are supported only as visibly broad request permissions in inspection/diagnostics. Embedded credentials, credential-like headers, oversize requests/responses, WebSocket URLs/upgrades, and SSE/event-stream requests are rejected.
