The pinned howlongtobeatpy (1.0.23) takes a user agent in
send_website_request_getcode and dropped parse_all_scripts; the call
still matched 1.0.20, which only worked because the deployed env was
behind its own pin. Now on the pinned API, and the env upgraded.
Three modules carried the same executable/path constant block since the
250-line split; it is _store_tools. Four carried the same "restore the
hours a refetch lost" loop; it is restore_prior_hours. Both detached
launches go through one helper that returns the process. Thirteen
try/except/else blocks are flat, dataclass fields come from
dataclasses.fields, and the rest are one-line fixes.

The enforce service runs as root (no User=) but sets DISPLAY=:0, so any GUI
it starts lands on the desktop session. Two resolvers disagreed about who to
drop privileges to:
library_hider._resolve_desktop_user() read STEAM_ENFORCER_DESKTOP_USER
game_install._get_real_user() read only SUDO_USER or USER
systemd sets neither of the latter, so _get_real_user() returned None under
the service and every `geteuid() == 0 and real_user and ...` guard fell
through to running as root. Steam answered with a zenity modal ("Cannot run
as root user", /usr/lib/steam/steam:261) on screen.
Confirmed from the live process tree: root `bash /usr/lib/steam/steam
-cef-disable-gpu ... steam://install/618510` with a root zenity child. It
never reached the journal, because that text goes to zenity and _run_as_user
sends child output to DEVNULL.
- _desktop_env: add resolve_desktop_user/desktop_uid/desktop_user_cmd. Only
the argv builder is shared, never the spawn call: tests/_no_subprocess.py
patches subprocess per module by name, so a spawn site in an unpatched
module could fire a real `sudo -u kuhy steam`.
- game_install._get_real_user: delegate to the shared resolver. This alone
also fixes the root `steam -silent` in _ensure_steam_running and the
no-op os.chown on new appmanifests.
- _trigger_steam_install / enforcer.send_notification: drop privileges.
send_notification had no DBUS_SESSION_BUS_ADDRESS, so it silently reached
nobody for all six of its callers.
- _run_as_user: fail closed. Running unchanged as root when no desktop user
resolves is what put the modal on screen; refuse and log instead.
Also stop the retry storm behind it. steamapps does not exist (Steam has
never completed sign-in), so is_game_installed() was always False and the
loop re-triggered every allowed game every pass: 1656 attempts in 30
minutes, service RSS 1.5 GB (peak 4.3 GB), a FileNotFoundError traceback
each time. Guard install_game and _reinstall_missing_allowed on
steam_library_ready() -- a missing library means no install can succeed by
any route, so this is a correctness check rather than a tuned retry limit.
The module splits here are forced by the pre-commit 250-line gate, which
blocks any commit touching an over-cap file: game_install, library_hider and
_enforce_loop were already over before this change. They are split by
responsibility (_cdp transport, _steam_launch lifecycle, _steam_process
spawning, _steam_errors, _steam_client, _game_names, game_uninstall,
_enforce_steps, _owned_apps_cache, _echo, _protected_apps). game_install and
library_hider re-export their old public names, so the 15 modules that
import from them are untouched by this commit.
Verified as real root under the unit's environment: argv is now
`sudo -u kuhy env DISPLAY=:0 ... xdg-open steam://install/...` for both the
installer and notify-send; three enforce passes spawn no process and log
once; _run_as_user refuses with no desktop user. After restart: 0 retries,
0 tracebacks, 0 root-owned files under ~/.local/share/Steam, RSS 342 MB.
1311 tests pass. _desktop_env and _steam_state at 100% branch coverage.
