+# EPM mod artifacts
+
+Drop-in `Content/Mods/EPM/` for Empyrion. Loaded by the dedicated server's
+mod loader; opens a TCP listener on `Settings.yaml.GameServerApiPort` (we
+ship `0.0.0.0:7028`, panel-allocated to whatever `EAH_API_PORT` env says).
+
+## Files
+
+- `EmpyrionNetworkRelayMod.dll` — the mod (`ModTargets: Dedi`). Compiled
+  from `EmpyrionNetworkConnectedMods/sample-empyrion-mod/Empyrion Mod/`
+  with one tweak: `Configuration.cs` was rewritten to manually parse
+  `Settings.yaml` (key: value lines) instead of using `YamlDotNet`. Reason:
+  current Empyrion 1.16.x ships `YamlAssembly.dll` rather than the old
+  `Assembly-CSharp-firstpass.dll` that bundled `YamlDotNet`, so the
+  upstream binary fails with `TypeLoadException` at `Game_Start`.
+- `EPMConnector.dll` — wire protocol library (TCP framing + protobuf-net
+  message dispatch). Linked by both EPM and any C# client.
+- `EmpyrionNetworkRelayMod_Info.yaml` — manifest. Per-DLL naming is
+  required because there are two DLLs in the folder; with a single DLL,
+  `Info.yaml` works, but with multiple Empyrion's loader needs each main
+  DLL to have a sibling `<DllName>_Info.yaml`.
+- `Settings.yaml` — host+port for the TCP listener. `0.0.0.0` is fine
+  inside the container (host networking limits exposure to the container
+  port; opnfwd handles WAN forwarding).
+
+## Verified end-to-end on 2026-04-30
+
+1. EPM loads under Wine: `Loaded Mod 'EmpyrionNetworkRelayMod': "EPM"`.
+2. TCP listener opens: `Now listening on port 7028`.
+3. C# probe (`/eah_probe/probe/Probe.cs`) connects via `EPMConnector.Client`
+   and gets typed protobuf-net responses for `Request_Get_Factions`,
+   `Request_Player_List`, `Request_Playfield_List`. Default Human
+   faction came back deserialized into `Eleon.Modding.FactionInfoList`.
+
+## How to rebuild
+
+1. Open `C:\Users\dbledeez\AppData\Local\Temp\eah_probe\EmpyrionNetworkConnectedMods\sample-empyrion-mod\Empyrion Mod\` (or re-clone from `MichaelGoulding/EmpyrionNetworkConnectedMods`).
+2. Replace `Configuration.cs` with the YAML-free version (see
+   `feedback_empyrion_yaml_dotnet_drop.md` for the snippet).
+3. `cd` to that folder and `csc.exe @build.rsp`. Output goes to
+   `bin\Release\EmpyrionNetworkRelayMod.dll`.
+4. Copy `EmpyrionNetworkRelayMod.dll` + `EPMConnector.dll` + the two yamls
+   into this directory; commit.
