H-A: by_form from a board word's fewest-endings reading, one word only;
by_readings at the fewest endings among the list's words, nowhere when
that word is on no board (つけて never つかれた, おくれた never おくる).
H-B: a board word is a noun only where its entry in its sense is one
(finder_ja.json classes "n"); the verb after を/が, or at the end after a
question word or adverb; the noun alone, after の, before a case particle.
M1: equal cost and one-kana words: more particles, then earlier.
M2: a board's <noun>する is a する verb where the list has the noun as one.
M3: two words of the list at the fewest endings lead nowhere but where
ja_inflect::DOMINANT settles it; after を, not an intransitive verb (kana
list "vi"; "adv" for adverbs).
