The enforcer runs as root under systemd and launches Steam via `sudo -u <user> env DISPLAY=... XAUTHORITY=... DBUS_SESSION_BUS_ADDRESS=...`. sudo uses env_reset, so that list is the child's entire environment - an allowlist where every omission fails silently. XDG_RUNTIME_DIR was missing. Without it Wine cannot reach $XDG_RUNTIME_DIR/pulse/native, falls back from winepulse.drv to winealsa.drv, and hands FMOD raw ALSA devices instead of the session sink. Kingdom Come: Deliverance II died in its Bink startup video as a result. Across 18 sessions the split was total: 9/9 runs logging "PulseAudio Output" exited cleanly, 9/9 logging "HDA NVidia" crashed on the same line. It presented as a corrupt install - the apparent cure was a 92GB reinstall - but verify-integrity always passed. What actually fixed it was the Steam restart the reinstall incidentally performed. Extract the duplicated env construction into _desktop_env.desktop_env_args and derive XDG_RUNTIME_DIR from the target uid, never from the ambient environment: root's own value would point the child at /run/user/0. PULSE_SERVER is deliberately not exported. pressure-vessel reads XDG_RUNTIME_DIR to bind-mount the pulse socket into the Steam Linux Runtime container, whereas a hardcoded unix:/run/user/<uid>/pulse/native names a host path that need not resolve inside it. Also gate the launch on the session existing. The enforcer is ordered only After=network-online, while /run/user/<uid> is created by user-runtime-dir@<uid>.service; on a measured boot the enforcer started 54ms before that unit and won only by doing other work first. Launching in that window would name a runtime dir that is not there and reintroduce the same silent winealsa fallback for the whole session, so defer instead - the enforce loop already retries every 3s, and DesktopSessionNotReadyError subclasses SteamUnavailableError so existing callers degrade as before. An ordering dependency would not be reliable here, since logind may start user-runtime-dir outside the boot transaction. Verified on the failing path rather than a dev shell: after restarting the enforcer, the Steam it launched carried XDG_RUNTIME_DIR=/run/user/1000 and KCD2 ran 15 minutes on "PulseAudio Output" with no crash artifacts.

Steam Backlog Enforcer
Forces you to 100% complete one Steam game at a time before moving on.
Features
- Achievement tracking: Picks the next game by shortest HLTB completionist time
- Store blocking: Blocks
store.steampowered.comvia/etc/hosts - Game uninstalling: Removes all installed games except the assigned one
- Process enforcement: Kills unauthorized game processes
- Tampering detection: Detects achievement unlocks on non-assigned games
- HLTB integration: Estimates completion time with persistent cache
Setup
python -m python_pkg.steam_backlog_enforcer.main setup
Commands
| Command | Description |
|---|---|
scan |
Scan library, fetch HLTB data, assign game |
check |
Check if assigned game is complete |
status |
Show current assignment and blocking |
list |
List incomplete games from snapshot |
skip |
Skip the currently assigned game |
enforce |
Run enforcer (block, uninstall, kill) |
unblock |

setup |
First-time configuration |
Enforce mode
sudo python -m python_pkg.steam_backlog_enforcer.main enforce
This will:
- Block Steam store in
/etc/hosts - Uninstall all games except the assigned one
- Continuously kill any unauthorized game processes
Game Uninstall
Directly removes appmanifest files and game directories from ~/.local/share/Steam/steamapps/.
Preserves Proton versions and Steam Linux Runtime.
python -m python_pkg.steam_backlog_enforcer.main uninstall
MCP server (Claude Code integration)
The enforcer exposes an MCP server (steam_backlog_enforcer._mcp) so Claude Code
and its subagents can query the backlog and drive it through typed tools.
- Read tools:
get_dataset,get_status,get_stats,list_backlog. - Gated write tools:
pick_manual,block_gaming— each defaults to a dry-run preview; passconfirm=trueto actually apply. These write tools must never be added to a permission allowlist (a subagent could otherwise bypass the human confirmation).
The mcp SDK is an optional dependency (pip install -e '.[mcp]'), kept out of
the CLI/systemd system-python path. One-time setup of the dedicated venv that
Claude Code spawns:
./scripts/setup_mcp.sh
Registration lives in the checked-in .mcp.json (project scope).
Restart Claude Code in this repo and approve the project MCP-server prompt for it
to load. Verify with claude mcp list.
