Delete the Qt host (src/, cmake/, CMakeLists.txt, find-qt.bat, check-setup.bat,
build.bat, deploy.bat) now that the Avalonia host in host/ covers it on the same
dotnet toolchain. Add a self-hosted host-build CI job and a host README, and
rewrite the top-level README for the C# server + Avalonia host layout.
The job-level env used runner.tool_cache, which isn't available until a
runner is assigned, so the workflow failed to parse. Set it on the
setup-dotnet step, where the runner context is valid.
setup-dotnet defaulted to /usr/share/dotnet, which the runner user cannot
write to (Permission denied). Point DOTNET_INSTALL_DIR at runner.tool_cache
so the 8.0 SDK installs into a writable, cached location.
- GnsTransport.cs: drop the illegal fixed statement on native.Debug (a
fixed-size buffer in a local struct is already pinned) -> CS0213 gone.
- ProtocolCore.cs: TryUInt32/TryDouble now accept int-backed JsonValues, not
only uint/long/double. Constructed JSON (and some wire values) box integers
as int, which were being rejected, failing player-state validation.
- MainWindow.cpp: drop 'Python' from a user string and a comment so the
no-legacy-runtime policy passes on the C# server.
- gns-transport.yml: the self-hosted runner has cmake/ninja/protobuf/openssl
pre-provisioned; replace the sudo apt-get step (no sudo in CI) with a
presence check that fails loudly if a dependency is missing.
Local: dotnet build clean, 13/13 server tests pass, legacy-runtime guard passes.
The ubuntu-latest job cannot start while GitHub-hosted minutes are
billing-blocked. Target the self-hosted Linux x64 runner, matching the
rest of the CI (csharp-server.yml, CO-BETA/beta-ci.yml).
Adds end-to-end Linux compatibility work for the dedicated server: new CI workflow (Ubuntu + Arch), line-ending/executable safeguards, and a local venv-first startup flow with split dependency files for server vs optional host GUI tooling. Improves runtime resilience with better bind error messages, stricter config validation, writable-state checks, cleaner socket/thread shutdown behavior, and SIGTERM-aware graceful stop handling for headless/systemd use. Updates deployment/startup docs and adds portability/runtime integration tests to lock in these behaviors.
