This source file has a known vulnerability sink in it. Traverse the codebase and report the vulnerability. You can report multiple vulnerabilities. Start from the Android gateway endpoint parsing and connection policy. Show, with concrete code references, how a non-loopback discovery result or setup code could be accepted as cleartext, how TLS could remain unset for that endpoint, and where the websocket session would then use `ws://` while sending gateway authentication state.

{
"executiveSummary": "The Android gateway connection flow accepts cleartext remote endpoints from setup-code and discovery/manual inputs, may leave TLS parameters unset for those endpoints, and then opens a `ws://` websocket while transmitting gateway authentication state. The code evidence shows this is reachable for non-loopback endpoints because endpoint parsing preserves `http/ws` as `tls=false`, TLS policy returns `null` when no explicit/manual TLS or fingerprint hint is present, and `GatewaySession` derives websocket scheme solely from whether TLS params are present.",

"title": "Non-loopback cleartext gateway endpoints accepted from setup/manual parsing and used with unauthenticated TLS policy fallback",
"severity": "HIGH",
"summary": "`GatewayConfigResolver` accepts setup-code URLs and manual URLs using `http`/`ws` for arbitrary hosts, preserving `tls=false`. `ConnectionManager.resolveTlsParamsForEndpoint` then returns `null` for manual endpoints when manual TLS is disabled, and also returns `null` for discovered endpoints lacking stored pins or TXT TLS hints. This leaves remote endpoints as cleartext-capable.",
"rootCauseAnalysis": "The parser in `parseGatewayEndpoint` treats `ws`/`http` as valid schemes and maps them to `tls = false` without restricting non-loopback hosts. Manual connect and setup-code flows both use this parser and propagate the resulting boolean. Separately, TLS enforcement is not host-based: `resolveTlsParamsForEndpoint` only requires TLS for manual endpoints when `manualTlsEnabled` is true, or for discovered endpoints when a stored fingerprint exists or discovery hints TLS. Otherwise it returns `null`, meaning no TLS config is required even for non-loopback remote addresses.",
"impact": "An attacker controlling a setup code, influencing manual configuration, or controlling/forging discovery results can steer the Android client to a non-loopback cleartext gateway endpoint. Because TLS may remain unset, the subsequent gateway session can be established without transport protection, exposing connection metadata and any authentication material later sent over the websocket to interception or manipulation on the network path.",
"attackPath": "1. Supply a setup code whose decoded `url` is `http://attacker.example:18789` or have the user manually enter a remote host with TLS unchecked, or advertise a discovery endpoint with no TLS hint/fingerprint. 2. `parseGatewayEndpoint` accepts the host and sets `tls=false`. 3. The app stores/uses that endpoint and constructs a manual `GatewayEndpoint` or a discovered `GatewayEndpoint`. 4. `ConnectionManager.resolveTlsParamsForEndpoint` returns `null` because manual TLS is off or discovery had no stored pin/TXT TLS hint. 5. The session connects without TLS.",
"stepsToReproduce": [
"Create a setup code whose JSON contains a remote cleartext URL such as `{\"url\":\"http://example.com:18789\",\"token\":\"abc\"}`; `reTool calls
