The reworked app's learner model hangs off cards: recall evidence, the
phase-review checklist, the practice set, and the gate's "words he has
met". So every word a unit introduces has to be studiable — and 16 of the
371 were not. Eleven existed only as sentence chunks or dictionary rows
outside the review deck, and five (봐 읽어 갔어 봤어 먹었어) nowhere at all.
The build now marks exactly one reviewable lemma per roadmap word with the
unit that introduces it. Where the deck has the word, its row is chosen
deterministically (deck order, then source, then part of speech) — the
artifact tagged whichever card came last, which put the evidence for 이, 눈
and 저 on the wrong meaning. The sixteen get a `curriculum` lemma of their
own, glossed from the curated verb they conjugate (자 is "sleep", the 반말
of 자다 — not the dictionary's "ruler"), else from the sentence that uses
them, else the dictionary.
Lemmas also carry their topic, which the vocabulary filters need.
dict:assert gains the guarantee: 371/371 roadmap words as one card each.
Migration 7 adds the two columns; the rows arrive with the dictionary
reload a changed build now triggers on its own.
