Self-contained research task. No engine internals needed. Roblox's settings document configures log channels, and the value shape is not uniform — most take a bare verbosity number (FLogNetwork = "7"), a minority take a severity name with an optional sub-level (FLogAudio = "Info", DFLogWebSocketTraceError = "Warning,6"). Giving a channel the wrong shape silences it, which is worse than doing nothing: flags.json [FLog::NativeDM] lines absent 29 {"FLogNativeDM": "100"} 0 {"FLogNativeDM": "Verbose"} 30 This cost this project a wrong conclusion that had to be retracted: a sweep of 135 channels set with bare integers was read as "loud logging is exhausted" when it had partly turned logging off. The binary defines 724 channels. The cached settings document (~/.cache/cordial/clientsettings.json) names the shape for every channel Roblox itself configures. Produce a table, and ideally make flags.json warn when a channel is given a shape that document disagrees with. Done when a
Cordial reports a made-up User-Agent and a base URL missing its trailing slash. The Waydroid capture of the same APK on real Android shows what the client actually sends. What Cordial sends (native/init_params.cpp, InitParams::Create): baseURL = "https://www.roblox.com" userAgent = "Roblox/Android" What the capture shows (docs/traces/waydroid-roblox-startup.log.gz): BaseUrl = www.roblox.com/ <- trailing slash User-Agent: ... ROBLOX Android App 2.732.1043 Tablet Hybrid GooglePlayStore RobloxApp/2.732.1043 The capture also shows setBaseUrl() null => www.roblox.com, which is worth understanding before changing anything — the client may be expected to pass null and let the engine default. Why it matters: these strings go out on every HTTP request. Roblox's own services parse the User-Agent for platform and version, so a wrong one may change what the server returns, and the trailing slash may or may not matter to path construction. Both are cheap to align and neither should b
