install_systemd.sh installed no dependencies at all, so on a fresh machine it died three times over: tkinter dlopens libtk8.6.so, which needs the `tk` package (the tkinter module itself ships inside `python`, so the package is `tk`, not `python-tk`), and gatelock and crdt-sync are pinned git dependencies in pyproject.toml that nothing ever installed. The post-install workout check crashed with ModuleNotFoundError and the installer exited 1 -- which is how install_core_system.sh reported "Workout screen locker" as failed on any machine that had not been set up by hand first. The last line was worse than that. It runs the real enforcer with --production, which builds a Tk UI and grabs the screen until a workout is logged. Driven non-interactively -- install_core_system.sh, CI, `vm run` -- it never returns, so the installer hung forever on its final statement rather than failing. It now only takes the blocking path when a terminal is present (or SCREEN_LOCKER_ENFORCE_AFTER_INSTALL=1), and otherwise prints --status and notes that the systemd units it just installed carry the enforcement. Verified in a pristine vmbox guest: install_systemd.sh exits 0 with tk, gatelock and crdt_sync installed on its own.

screen-locker
Tkinter/systemd screen locker with workout tracking, sick-day management, and wake-alarm integration. It enforces a workout cadence by locking the screen until a RunnerUp-verified (or explicitly justified) workout is logged.
MCP server (Claude Code integration)
screen-locker exposes a read-only MCP server (screen_locker._mcp) so
Claude Code and its subagents can query workout compliance and the
lock-decision state through typed tools — without shelling out to the
screen-locker-status CLI or opening the Tk window.
- Read-only tools:
get_status(full status snapshot),get_summary(one-line i3blocks summary +ok/warn/lockstate word),explain_lock(why the screen is / isn't locked right now),get_flags(the individual boolean lock-decision predicates for today). - There are no write/action tools, by design. Nothing here logs a workout or mutates state — workouts are logged only from RunnerUp-verified TCX data, never from a caller's claim. No tool exposes the sync token or any HMAC key.
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.
