 ### Added
 
+- JSON Hunting Road config: `bin/rengoku_data.json` is now supported as a human-readable alternative to the opaque `rengoku_data.bin` — the server assembles and ECD-encrypts the binary at startup, with `.bin` used as a fallback ([#173](https://github.com/Mezeporta/Erupe/issues/173)).
 - JSON quest files: `.json` files in `bin/quests/` are now supported alongside `.bin` — the server tries `.bin` first (full backward compatibility), then compiles `.json` on the fly to the MHF binary wire format ([#160](https://github.com/Mezeporta/Erupe/issues/160)). Covers all binary sections: quest text (UTF-8 → Shift-JIS), all 12 objective types, monster spawns (large + minion), reward tables, supply box, loaded stages, rank requirements, variant flags, forced equipment, map sections, area transitions, coordinate mappings, map info, gathering points, gathering tables, and area facilities. A `ParseQuestBinary` reverse function allows existing `.bin` files to be inspected and exported to JSON.
