| ## 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. |
