Kaomoji flag
The SQLite kaomoji column (0/1) marks symbol-structured emoticons; filter
with WHERE NOT kaomoji for a face-free dictionary. A candidate is flagged
when it matches an ASCII emoticon (:-), orz, T_T), looks structurally
like a kaomoji (bracket / face-mark / arm-mark heuristics, <= 48 chars), or
is sourced solely from the project's kaomoji dictionaries. Unicode emoji are
legitimate conversions and are NOT flagged.
Cost calibration
Costs are on Mozc's word-cost scale; layers merged in order, the first
provider of a (reading, candidate) wins. Project-original dictionaries were
quantile-mapped onto Mozc via their shared entries, Mozc was added
unchanged, then each remaining layer was isotonic-calibrated on its overlap
with the pack and offset by a fixed penalty, adding only novel entries:
ipadic +5000, sudachi +6000, skk (core subset) +5000. Pre-normalization: sudachi clamp(7000 + cost/4, 6000, 16000); original emoji files 18000 + clamp(cost, 0, 10000)/2; other
original files clamped to per-file floors (default 4500) and a 30000
ceiling.
