The PWA manifest declared icon-192.png, icon-512.png and favicon.svg. None
of the three existed, so install-to-home-screen and the browser tab both
resolved to nothing. That was a defect in what the last pass claimed as
done.
Drawn procedurally with Pillow rather than authored as SVG: there is no
dependable SVG rasteriser here to convert from, and ImageMagick falls back
to its MSVG renderer, which cannot be trusted with text. Pillow's
FreeType + RAQM stack shapes Hangul correctly, which is the only hard
requirement. The mark uses the app's own register — the serif face already
used for 한칸 on the boot screen, in --jade on --bg.
Two glyphs read well at 180px and up; at favicon sizes 한칸 turns to mush,
so the small sizes carry 한 alone.
icon-192 · icon-512 · apple-touch-icon (180) 한칸
icon-512-maskable 한칸 at 56%, inside
Android's circular crop
favicon.ico (16/32/48) · favicon-32 한
Sizing is a binary search on the drawn ink extent, and centring uses the ink
bounds rather than the font's line box — CJK metrics leave asymmetric space
above and below, which would otherwise sit the mark visibly high.
Re-running the generator writes byte-identical files.
Android launcher icons are untouched; Android work is out of scope.

Closes REVIEW.md §2. 167 of 371 roadmap words had no lexicon entry, so the
word rail silently showed nothing. Now:
Roadmap words: 371/371 resolve
Spiral targets: 35/35 resolve
Deck words: 386/386 resolve
and npm run dict:assert makes it a blocking build failure, not a silent
empty rail.
No runtime morphological analyser ships. lib/conjugation.js surfaceForms()
runs at BUILD time over every verb and adjective, so looking up a conjugated
form is an index hit on the surface table.
The frequency join had to be inverted. A subtitle frequency list holds
surface forms; a dictionary holds lemmas whose -다 citation form barely
occurs in running text, so joining on headword gives verbs a frequency of
roughly zero. Expanding each lemma into the forms it plausibly takes and
summing recovers 하다 from 118 to 89,041. Forms claimed by more than one
lemma are dropped rather than split, so homographs don't inherit each
other's mass. Those expansions score frequency only — the surface table
itself stays strictly surfaceForms() output plus the headword.
Bands are one per curriculum phase. Phase 1 admits no frequency band at
all: during the writing-system phase every word must be phonologically
legal for the unit reached, and a rank ceiling would hand the learner a
겹받침 during unit 1.4. shared/phonology.mjs lifts validate.mjs's own
feature ladder to enforce that; it agrees with the validator on all 371
words.
Sources are chosen automatically — KRDICT when vendored, otherwise the
kaikki.org extract. KRDICT's download is a JS form behind anti-bot
protection, so it cannot be fetched by CI; the derived band files are
committed instead, which the app needs offline regardless. Attribution and
the share-alike terms are in NOTICE.md.
