Tapping a word in a poem now opens its meaning. Neither source covers enough
alone — Daneshjoo reaches 71% of real poem vocabulary — so both ship, each row
carrying its source so the credit stays attached and either can be dropped
later. Together with the lookup chain that reaches 88%, and 13 of the 55
remaining misses are Arabic lines quoted inside Persian poems.
Lookup widens until something matches: the word as written, the lemma it
inflects from, the word with an affix stripped, then the parts of a ZWNJ
compound. The lemma step is what makes classical verse readable, and it comes
from Wiktionary's 149,589 form->lemma pairs: افتاد is only findable as افتادن.
The Arabic definite article is stripped too, since poems quote Arabic.
Two things the build taught me. Wiktionary's 93 MB export is 0.94 MB of
definitions wrapped in inflection tables, etymology templates and IPA, so
tools/build_dictionary.py keeps the definitions and the form index and drops
the rest. And the packager silently gunzips .gz assets and strips the
extension, which shipped the database under a name the code wasn't opening —
every lookup failed silently until the APK listing gave it away.
Hit testing needed care as well: nastaliq is set with 2.4x leading, so most of
a line box is empty space, and a tap there clamps to the line's first
character — which made every tap return the opening word. Taps are now checked
against the baseline band, with the multipliers left as a knob for swapped
fonts. Definitions are English, so they read left-to-right inside the
otherwise right-to-left sheet.
Verified on the release build, where R8 could have broken the SQLite path:
tapping عشق returns both sources, and دانند resolves to دانستن.
