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-v0.10.0
      path: crdt_sync_dart

sync_settings_ui/

Shared Flutter "Sync settings" screen (pub package name: sync_settings_ui, not published to pub.dev). Firebase sync (primary) plus an optional local backup slot — no GitHub mirror UI. Pure UI + a FirebaseSyncController service layer over injected closures (keystore/Google-plugin access stays in each consuming app, exactly as before this package existed). Consumed by todo, diet_guard_app, workout_app, wake_alarm/phone_app, and home_inventory's dedicated "Sync settings" route.

Consume via:

dependencies:
  sync_settings_ui:
    git:
      url: https://github.com/kuhyx/utils
      ref: sync_settings_ui-v0.1.0
      path: sync_settings_ui

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

music_theory/

Music theory from first principles as typed Python (package: music_theory, not published to PyPI): pitch, tuning, scales, chords, progressions, a numpy synth and a Recipe → WAV composer with a degrade transform. Follows Luke Haas's "Music Theory for Programmers" section by section; python -m music_theory demo all --out DIR renders one WAV per section. Consumed by roadside-assistance for its three world-state music beds.

Consume via:

music_theory @ git+https://github.com/kuhyx/utils@music-theory-v0.1.0#subdirectory=music_theory

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 DOCS-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.
