 ### Added
 
+- French (`fr`) and Spanish (`es`) server language translations. Set `"Language": "fr"` or `"Language": "es"` in `config.json` to activate.
+- `TestLangCompleteness` uses reflection to verify that every string field in `i18n` is populated for all registered languages — catches missing translations at CI time rather than silently serving empty strings in-game.
+- Server-generated strings (commands, mail templates, Raviente announcements, Diva bead names, guild names) are now split into one file per language (`lang_en.go`, `lang_jp.go`, etc.). Adding a new language requires only a single self-contained file and a one-line registration in `getLangStrings` ([#185](https://github.com/Mezeporta/Erupe/issues/185)).
 - Hunting Tournament system: all six tournament handlers are now fully implemented and DB-backed. `MsgMhfEnterTournamentQuest` (0x00D2) wire format was derived from `mhfo-hd.dll` binary analysis. Schedule, cups, sub-events, player registrations, and run submissions are stored in five new tables. `EnumerateRanking` returns the active tournament schedule with phase-state computation; `EnumerateOrder` returns per-event leaderboards ranked by submission time. `TournamentDefaults.sql` seeds cup and sub-event data from live tournament #150. One field (`Unk2` / event_id mapping) remains unconfirmed pending a packet capture ([#184](https://github.com/Mezeporta/Erupe/issues/184)). Database migration `0015_tournament` (`tournaments`, `tournament_cups`, `tournament_sub_events`, `tournament_entries`, `tournament_results`).
 - Return/Rookie Guild system: new players are automatically placed in a temporary rookie guild (`return_type=1`) and returning players in a comeback guild (`return_type=2`) via `MSG_MHF_ENTRY_ROOKIE_GUILD`. Players graduate (leave) via `OperateGuildGraduateRookie`/`OperateGuildGraduateReturn`. Guild info response now reports `isReturnGuild` correctly. Database migration `0014_return_guilds` adds `return_type` to the `guilds` table.
 - `saveutil` admin CLI (`cmd/saveutil/`): `import`, `export`, `grant-import`, and `revoke-import` commands for transferring character save data between server instances without touching the database manually.
