On 2026-08-03 the screen locker's lock screen scrolled to mid-content and back with nobody touching the keyboard, on a 1366x768 panel. Measured under Xvfb with the real app: one programmatic focus_set() produced three scrolls, frac 0.000 -> 0.436 -> 0.145. Two causes, both here: * ScrollableSurface followed every <FocusIn>. The apps focus a widget on every repaint (and gatelock re-asserts focus from its recovery tick), and Tk delivers <FocusIn> to the focused widget's whole ancestor chain when the toplevel takes X focus -- so each repaint aimed a scroll at containers taller than the screen. Now a focus move scrolls only when it followed a real keypress, or a click on the widget that took focus, and only for a leaf. Tab onto a clipped field still reveals it; nothing else moves. * finalize()'s reset-to-top cancelled the centring, because centring moved the canvas item down and the region's top edge with it. The region is now pinned to the viewport whenever the content fits, so the view cannot move at all, the scrollbar is taken down, and centring survives the repaint. Content that does not fit is a layout defect, not a mode to live in, so finalize() reports it at warning and gatelock.measure_fit() lets each app gate on it before shipping (scripts/verify_screen_fits.py in all four). Also: LockConfig's type/space scales now compact below 768px (_density), which is where a screen has no room to be at design-system size and no scrollbar to make up for it. 768 and up is verified to fit at full size, so it is never compacted. Tests: _scrollable had none; the regression is now stated as code (programmatic focus must not move yview; Tab must). 323 pass, coverage 95.38% -> 99.44%.

utils
Shared libraries used across kuhyx's other projects. Each subdirectory is a
formerly-standalone repo, folded in here with full commit history preserved
(see each subdirectory's own git log for its pre-merge history).
crdt_sync_dart/
Dart/Flutter CRDT sync library (pub package name: crdt_sync, not published
to pub.dev — consumed via a git dependency). Mirrors crdt-sync (below)
module-for-module and test-for-test. Consumed by diet_guard's app,
screen-locker's workout_app, wake_alarm's phone_app, and todo (whose
notes are stored in the v0.2.0 LogStore).
Consume via:
dependencies:
crdt_sync:
git:
url: https://github.com/kuhyx/utils
ref: crdt_sync_dart-v0.2.0
path: crdt_sync_dart
crdt-sync/
Python CRDT sync library (package: crdt_sync, not published to PyPI). Same
design as crdt_sync_dart (HLC clocks, per-field LWW, sticky-delete
tombstones). Consumed by diet-guard and screen-locker.
Consume via:
crdt-sync @ git+https://github.com/kuhyx/utils@crdt-sync-v0.2.0#subdirectory=crdt-sync
guard-lib/
Bash tamper-resistance primitives (guardctl: chattr + bind-mount + systemd
watcher + pacman hooks). Not a package — installed by running
guard-lib/install.sh as root, which copies files onto the system
(/usr/local/bin, /usr/local/lib/guard-lib, systemd units, pacman hooks).
Consumed by steam-backlog-enforcer (expects a guard-lib/install.sh
sibling clone) and referenced by screen-locker.
gatelock/
Python lock-window + HMAC log-integrity backend (package: gatelock, not
published to PyPI). Consumed via pip by screen-locker, diet-guard, and
wake-alarm:
gatelock @ git+https://github.com/kuhyx/utils@gatelock-v0.1.0#subdirectory=gatelock
unified-design-system/
Not a package — the frozen design tokens (colors, spacing, type, radius,
shadow policy) and per-stack (Flutter/web/Tkinter) implementation patterns
that keep every one of kuhy's repos visually identical, plus annotated
component references (components.html, button.html). Read
unified-design-system/README.md and
tokens.md before touching any theme/CSS/style file in any repo. The
unified-design-system Claude Code skill is a thin pointer here, not a
duplicate.
