New subproject porting Luke Haas's "Music Theory for Programmers" section by section into typed Python: pitch (MIDI <-> Hz), tuning (harmonic series, the Pythagorean comma, brute-forced "why twelve"), scales as step arrays with modes as rotations, chords stacked in thirds with Roman numerals and the V7 -> I resolution, named progressions, a numpy synth (waveforms, ADSR, low-pass), a bar-exact sequencer, and a seeded Recipe -> WAV composer. `degrade` is the same piece ruined by a 0..1 amount, so an ending can be the opening destroyed on the same seed; filtering runs LAST because filtering first measured brighter than the clean render. 17 demos (`python -m music_theory demo all`) each print the article's numbers -- the comma is 1.013643, the tempered fifth is 0.113 % flat, twelve is the first acceptable division -- and the FFT of the render, so the claims are tested rather than asserted. 157 tests, 100 % branch coverage, ruff ALL, mypy strict, pylint 10. Consumed next by roadside-assistance for its three world-state beds. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VC17zymxkeiUcHrMvt8W5W

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.

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.
