+MelonLoader 0.6.x mod that retargets the 2020 Rec Room client at a
+DorkNet server. Compiles to `DorkNet.ClientMod.dll`, which the patcher
+drops into the user's `Recroom_Release/Mods/` folder.
+
+## What it does
+
+Harmony patches applied at boot:
+
+- **`Uri ctor`** — rewrites every `.rec.net` URL to your configured
+  server host. Catches every hardcoded API endpoint the watch ships with.
+- **`PhotonNetwork.ConnectUsingSettings`** — overrides the baked-in
+  Photon Cloud AppId with yours.
+- **`NetworkingPeer.CallAuthenticate`** — injects `userid` + `LoginLock`
+  into Photon's CustomAuth so your server can identify the player.
+- **`BouncyCastle.Tls.*NotifyServerCertificate`** — bypasses TLS chain
+  validation. The 2020 client only trusts a baked-in cert set; we replace
+  the verifier so any cert from your server is accepted. (Mitigated by
+  also force-routing only to your configured host.)
+- **`PlayerEmotes.RemoveInvalidCharactersFromMessage`** — skips the
+  TMP font-validation step that NREs when the font asset isn't loaded
+  yet (private servers don't always have it cached at chat-send time).
+- **`AccountExtensions.CanLocalPlayerChat`** — forces chat-enabled for
+  Junior / restricted accounts (single-tenant private server, no chat
+  moderation needed).
+
+See `Mod.cs` for the full patch list with citations to the Cpp2IL
+disassembly that justifies each one.
+
+## Config
+
+The mod reads `MelonLoader/UserData/dorknet-clientmod.json`:
+
+```json
+{
+  "ServerHost": "abc-def.trycloudflare.com",
+  "PhotonAppId": "your-photon-realtime-appid",
+  "PhotonCloudRegion": "eu",
+  "InjectAuthValues": true,
+  "EnableTlsTrustBypass": true
+}
+```
+
+The patcher (desktop app and CLI) writes this file as part of the patch
+flow — users don't normally edit it by hand.
+
+## Building
+
+```bash
+dotnet build -c Release
+# → bin/Release/DorkNet.ClientMod.dll
+```
+
+Requires Il2Cpp interop assemblies from the user's MelonLoader install.
+Path defaults to `dist/RecRoom-Clean-2020.03.10/MelonLoader/`; override
+with `-p:MelonLoaderDir=<path>`.
