Each file split at a class or concern boundary, never mechanically: test_arbiter.py 432 -> 222 + _lifecycle 183 + _release 201 test_outputs.py 418 -> 187 + _randr 204 + _enumerator 126 test_scrollable.py 374 -> 231 + _into_view 197 test_escape.py 343 -> 175 + _budget 216 test_window_surfaces 341 -> 110 + _lifecycle 104 + _preempt 182 test_surfaces.py 282 -> 167 + _focus 154 test_window.py 269 -> 143 + _grab 139 Test counts verified against a clean HEAD worktree, per file group rather than in aggregate: arbiter 49/49, outputs+escape 84/84, window+surfaces 72/72, scrollable 18/18. The whole suite is 389 passed at 100% branch coverage, identical to before. The one non-mechanical part: _reply/_randr_display are module-level helpers defined *between* classes, so they did not travel with the header and had to be moved to the RandR file by hand — six tests failed until they did.

gatelock
Shared fullscreen lock-window + HMAC log-integrity backend, extracted from three personal automation tools that each independently implemented "lock the screen with a blocking overlay until a condition is met": diet_guard, wake_alarm, and screen-locker.
Why
All three reimplemented the same tkinter fullscreen mechanics (overrideredirect,
input grab, VT-switch disable) at different levels of maturity, and the
HMAC-signed-state module had already been hand-copied between two of them
because they live in separate repos. gatelock is the one place that logic
now lives.
Install
pip install "gatelock @ git+https://github.com/kuhyx/utils@gatelock-v0.1.1#subdirectory=gatelock"
Usage
import tkinter as tk
from gatelock import GateRoot, LockConfig, LockWindow
class MyGate:
def __init__(self, *, demo_mode: bool) -> None:
self.root = GateRoot()
self.root.on_callback_error = self._handle_callback_error
config = LockConfig(mode="soft" if demo_mode else "hard")
self._lock = LockWindow(self.root, config, hooks=self)
self._lock.setup()
# ... build your widgets ...
self._lock.grab_input()
def on_focus_ready(self) -> None:
self.my_entry.focus_force()
def on_callback_error(self) -> None:
self.close()
def on_close(self) -> None:
... # release any hardware/state held while locked
def close(self) -> None:
self._lock.close()
def run(self) -> None:
self._lock.run()
LockConfig's mode preset bundles the common combination ("soft" = topmost
only, typeable, WM-escapable; "hard" = overrideredirect + global grab +
VT-disable). Each axis (overrideredirect, grab, disable_vt,
grab_retry_ms) can be set explicitly to reproduce a consumer's exact prior
behavior where it diverges from the preset.
gatelock.log_integrity ports the HMAC-signed state module used by all three
projects; DEFAULT_HMAC_KEY_FILE (/etc/workout-locker/hmac.key) is
unchanged so existing signed history keeps verifying.
