+# EVE Program Output
+
+## Authority Map
+
+- Owner: Fensalir owns the visible D3D12 program pixels.
+- Inputs: Fensalir reads the current `AquariumFrame`, render plan, GPU resources,
+  and overlay state.
+- Outputs: a named shared D3D12 `B8G8R8A8_UNorm` texture containing the completed
+  backbuffer for the current frame.
+- Derived state: Mimir publication profiles describe the stream contract; they
+  do not render pixels. EVE receives decoded pixels and composites them.
+- Forbidden writers: WebKit, DOM layout, browser dashboards, OBS capture, and
+  desktop/window capture do not own this path.
+- Shared paths: local display and EVE streaming both use the same completed
+  Fensalir backbuffer copy.
+- Deletion line: diagnostic Sunshine/Moonlight or desktop-duplication probes may
+  prove network/decode budget, but they are not production authority.
+
+## Current Mechanism
+
+Set these before launching the Mimir app:
+
+```powershell
+$env:FENSALIR_PROGRAM_OUTPUT_D3D12 = "1"
+$env:FENSALIR_PROGRAM_OUTPUT_NAME = "Global\MimirFensalirProgramTexture"
+dotnet run --project .\src\Mimir.App\Mimir.App.csproj
+```
+
+Fensalir creates a shareable D3D12 texture with that name and copies the finished
+backbuffer into it during the present pass. A hardware encoder process should
+open that named texture, encode H.264/HEVC with GPU hardware, and send frames to
+EVE's native receiver.
+
+`scripts/start-eve-program-output.ps1` starts the Mimir/Fensalir app with the
+shared-texture output enabled and verifies the `eve` SSH target before launch.
+
+## Receiver Contract
+
+EVE owns:
+
+- network receive;
+- hardware decode;
+- texture upload/import;
+- final fullscreen composite;
+- touch/Pencil/sensor uplink later.
+
+EVE does not own:
+
+- dashboard DOM;
+- Chromium/WebKit compatibility;
+- layout parity;
+- Mimir timing authority;
+- OBS composition authority.
+
+## Smoke
+
+```powershell
+dotnet run --project .\src\Mimir.BufferSmoke\Mimir.BufferSmoke.csproj -- --eve-program-output-contract-smoke
+```
