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.
