A Sunday ran past the 6.0h the i3 bar showed: 2h47m of Saturday's
leftover was carried into the budget the cutoff used, and the 3-second
"Gaming budget" journal line omitted it. Unspent time is now dropped at
06:00 every day; load_state takes a legacy ledger's share back out of
today's high-water mark. The budget line logs only on change (was 25k
lines/day), fired warnings are logged, and budget.jsonl records carry
budget_seconds.

A qualifying game process running is now sufficient on its own to bill
the budget. Previously a tick only counted if the screen wasn't locked,
the game's window was X11-focused, and input hadn't gone idle for 5
minutes — with an idle-grace refund on top. That leniency is gone
entirely: no focus check, no idle check, no screen-lock check, no
refund. Deletes the engagement-probing modules (_playtime_engagement,
_engagement_probes, _engagement_types, _x_focus, _x_probe, _screen_hold,
_controller_input) and their config fields, simplifies the audit log
and budget-view/web session schema accordingly.

`requires-python` and the CI pin already said 3.14, but ruff, mypy and pylint
were still grading against 3.10 -- three tools judging an interpreter nothing
runs any more, and ruff withholding the pyupgrade fixes that only become safe
at the newer target. `pin_ci_python.py` rewrites exactly these three knobs.
What the stale target was hiding: `datetime.timezone.utc` where `datetime.UTC`
is now correct (UP017), `socket.timeout` where `TimeoutError` is (UP041),
deprecated `typing` imports (UP035), PEP 695 `type` aliases (UP040), and ruff's
stable formatter applying PEP 758 -- `except (A, B):` becomes `except A, B:`.
That last one makes the source 3.14-only at the syntax level, which is what
`requires-python = ">=3.14"` already promised; kuhy chose it deliberately over
holding ruff a release back (2026-08-29).
ruff, ruff-format, mypy --strict and pylint all clean at the new target. The
two modified web/ TypeScript files are another session's in-flight work and
are deliberately left unstaged.

A running game process was treated as proof of play. On 2026-08-28 the budget
billed ~2h23m while a gatelock screen locker covered the display and the
machine could not be touched at all -- the game was simply still resident.
A tick now bills only when all three hold, evaluated together rather than
short-circuited so the audit log can answer "was the screen ALSO locked?":
* no gatelock guard owns the screen (_screen_hold, via /proc/locks)
* the focused window belongs to a qualifying process or its ancestry
* some input source has been used within idle_grace_seconds (default 300)
Any probe that cannot answer BILLS the tick and is recorded in `degraded`.
A broken detector must never become an unlimited-gaming exploit.
Three findings from measuring this machine rather than assuming:
* /dev/input/js0 here is an *ASRock LED Controller* -- the kernel exposes
the motherboard RGB device as a joystick. A presence check would have
disabled the idle criterion permanently, so _controller_input watches for
real events instead (skipping joydev's synthetic open burst).
* Aseprite's window carries no _NET_WM_PID at all, so focus attribution
falls back to XRes, which asks the server who owns the window rather than
trusting the client to have announced itself.
* /proc/locks reports gatelock's hold without taking it; gatelock's own
read_claim_if_held detects held-ness by acquiring, which would race a
guard every 3 seconds.
Idle pauses also refund the grace period once per walk-away, on the
engaged->paused edge only, never across a day rollover, and never on the first
tick after a restart -- the only place the counter moves backwards.
Everything is recorded to /var/log/steam-backlog-enforcer/budget.jsonl, on
change plus a heartbeat rather than one line per 3s tick. Records name the
qualifying PIDs: reconstructing this incident from journald alone was only
possible by inferring accrual from the spacing of two warning notifications.
Also: refuse to bounce Steam while a game is running. ensure_steam_debug_port
relaunches Steam when the CDP port is closed, which kills the running game --
that is how restarting the daemon to deploy this change ended a live session.
It now defers exactly as it already did for in-flight game updates.
Talks to X through ctypes over one cached connection: at a 3s tick, forking
xprintidle and xprop would cost ~40 forks a minute.
