+# Architectural Response
+
+**Re:** REQ-2026-04-13-rules-mod-config-fix-versioning
+**Date:** 2026-04-13
+
+## 1. Verdict
+Fixed in v1.0.2. Root cause was `ModConfig.Type.SERVER` — switched to `COMMON`.
+
+## 2. What Changed
+- SERVER configs in `world/serverconfig/` are tied to world load/unload lifecycle — Forge overwrites them every restart
+- COMMON configs in `config/` load once at startup and persist reliably
+- Config path: `config/firefrostrules-common.toml` (was `world/serverconfig/firefrostrules-server.toml`)
+- Loading handler + version bump to 1.0.2 applied to all 6 builds
+- 1.16.5 uses `ModConfig.Loading` (inner class), 1.20.1+ uses `ModConfigEvent.Loading`
+
+## 3. Deliverables (all committed + pushed)
+- firefrostrules-1.0.2-1.21.1-neoforge.jar
+- firefrostrules-1.0.2-1.20.1-forge.jar
+- firefrostrules-1.0.2-1.16.5-forge.jar
+- discord-rules-1.0.2-1.21.1-neoforge.jar
+- discord-rules-1.0.2-1.20.1-forge.jar
+- discord-rules-1.0.2-1.16.5-forge.jar
+- CHANGELOG.md, INSTALL.md, CLAUDE.md updated
+
+## 4. Otherworld Deploy Steps
+1. Stop Otherworld
+2. Replace jar with firefrostrules-1.0.2-1.20.1-forge.jar
+3. Delete old world/serverconfig/firefrostrules-server.toml
+4. Start server — generates config/firefrostrules-common.toml
+5. Stop — edit config with real values
+6. Start — values persist
+7. Restart again — confirm persistence
+8. Player runs /rules — real Discord rules show
