+## WHAT WAS COMPLETED THIS SESSION (Session 8: Admin Endpoint Fix)
+
+### Fixed Admin API Endpoint Paths — COMPLETE ✅
+
+**Issue:** Phase 3 split admin/config.py into ai_config.py and db_config.py with new route paths, but frontend was still calling old endpoints, causing 404 errors.
+
+**Solution Implemented:**
+- Updated `frontend/lib/api.ts` (7 changes):
+  - `getAiPrompt()` — `/admin/db/settings/prompt` → `/admin/ai/settings/prompt`
+  - `updateAiPrompt()` — `/admin/db/settings/prompt` → `/admin/ai/settings/prompt`
+  - `getAiConfig()` — `/admin/db/settings/ai` → `/admin/ai/settings`
+  - `updateAiProvider()` — `/admin/db/settings/ai` → `/admin/ai/settings`
+  - `updateAiKeys()` — `/admin/db/settings/ai-keys` → `/admin/ai/settings/keys`
+  - `testAiKey()` — `/admin/db/settings/test-ai-key` → `/admin/ai/settings/test-key`
+  - `getSystemSettings()` — Updated prompt fetch to use `/admin/ai/settings/prompt`
+
+**Test Results:**
+- Frontend: **291/291 passing** ✅
+- Backend: **41/41 passing** ✅
+- No 404 errors on admin API calls
+
+**Commit Created:**
+- `63364c1d` fix: update admin API endpoint paths to match split routers
+
+**Status:** Ready for merge. All endpoints now correctly route to split admin config routers.
