History
Krzysztof kuhy Rudnicki e971bf73bb Add focus_owner and a padlock-closed glyph to the icon family 
focus_owner (com.kuhy.focus_owner, the Device Owner enforcer) was the one
Flutter app never registered with the shared generator. It shipped a
hand-written vector adaptive icon added purely to unblock its build — the app
had no icon resource at all and every release AND debug build failed on AAPT
"resource mipmap/ic_launcher not found". That placeholder used #E8EAED, so it
was off-family as well as unregistered.

None of the existing 13 glyphs fits a device-policy enforcer, so this adds
padlock-closed: shackle stroked (inheriting the group's round caps), body
filled in the accent, keyhole punched back out in the field colour. A fully
stroked padlock loses its keyhole at 48dp and a fully filled one loses the
shackle's opening; splitting them keeps both.

Geometry was computed against style.py's constraints rather than eyeballed,
per the lesson recorded on _NOTE_ASCENDER: body 292..732 x 520..792, shackle
centreline r=132 about (512,520) so its outer top is 352 (inside the 232 safe
edge) and its legs land at 380/644, well within the body. The keyhole leaves
60px of body above it and 76px below the stem, both clear of
MIN_NEGATIVE_SPACE=36 — checked by rendering at 48px, where the hole survives.

The repo path points into ~/phone-focus-mode/focus-owner: focus-owner was
absorbed as a subtree on 2026-08-24 and both the standalone clone and its
GitHub repo are gone.

app_icons stays at 100% branch coverage; 44 tests pass.

README.md

app_icons — shared launcher icons for the Flutter apps

One icon family across every Flutter/Dart app: a charcoal #211D1B field with a single glyph in the shared unified-design-system accent (#B8862E), drawn at one stroke weight and optically centred so a row of them lines up.

Commands

# what is registered
PYTHONPATH=~/testsAndMisc python3 -m python_pkg.app_icons list

# contact sheet for visual review: full size / circle-masked / 48dp
PYTHONPATH=~/testsAndMisc python3 -m python_pkg.app_icons preview -o /tmp/sheet.png

# write assets into every app repo and rebuild the Android mipmaps
PYTHONPATH=~/testsAndMisc python3 -m python_pkg.app_icons generate --android

# one app, plus the hicolor PNGs for a Linux desktop target
PYTHONPATH=~/testsAndMisc python3 -m python_pkg.app_icons \
    generate --app todo --android --linux-out ~/todo/linux/icons

What gets written

Per app, into <repo>/assets/icon/:

Layer Purpose
icon Charcoal field + glyph. Legacy square launcher icon and Linux icon.
icon_foreground Glyph only, transparent. Adaptive-icon foreground layer.
icon_monochrome Glyph only, white. Android 13+ themed icons.

Both an .svg source and a 1024px .png are written for each, so a build never needs rsvg-convert. flutter_launcher_icons then turns the PNGs into the density buckets and mipmap-anydpi-v26/ic_launcher.xml.

Design constraints that bite

  • Negative space ≥ half the stroke weight. Strokes closer than that merge into a solid blob at launcher size. A fork whose tines sat exactly one stroke width apart rendered as a tulip.
  • Ink must stay inside the 560px safe box. Android masks adaptive icons to roughly the inner 66% of the canvas. generate warns when a glyph overflows.
  • Stroked outlines can read wrong. A stroked three-tine fork reads as a trident; a filled fork-and-knife pair reads as cutlery. Prefer a filled silhouette when the outline is ambiguous.
  • Glyph positioning inside the fragment is irrelevant — render.centre_offset measures the rendered ink and recentres it. Only the extents matter.

Adding an app

See the app-icon skill (~/.claude/skills/app-icon/SKILL.md) for the full procedure. In short: add a glyph to glyphs.py, register the app in apps.py, wire flutter_launcher_icons into its pubspec.yaml, generate, review the contact sheet, then verify on the phone.

Tests

cd ~/testsAndMisc
python3 -m pytest python_pkg/app_icons --cov=python_pkg.app_icons \
    --cov-report=term-missing

External tools (rsvg-convert, magick, dart) are mocked; the suite needs none of them installed.
