+## [Archived] Claude (Sonnet 4.6) — 2026-04-11 — Login Loop Fix Attempt
+
+**Active AI:** Claude (Sonnet 4.6)
+**Archived:** 2026-04-11
+**Version:** v1.3.5 | **Branch:** dev
+
+### What was broken when this session started
+- Login succeeds (LDAP user `bede`) but main page immediately redirects back to `/login`
+- Root cause: axiosInstance in `frontend/lib/api.ts` initialized at SSR time with wrong baseURL (`http://localhost:8000` instead of `https://192.168.84.140:3002`)
+- 401 interceptor redirects unconditionally — no guard for "already on /login"
+- No token guard on `page.tsx` before API calls fire
+
+### What this session did
+1. `frontend/lib/api.ts` — axiosInstance baseURL now lazy (set in request interceptor, not at module init)
+2. `frontend/lib/api.ts` — 401 interceptor now guards: `!window.location.pathname.includes('/login')`
+3. `frontend/app/page.tsx` — token guard added to BOTH useEffect hooks (first one calls `getCategories`, second calls `loadInventory`)
+4. `frontend/lib/auth.ts` — removed debug console.log statements
+5. `frontend/app/login/page.tsx` — removed debug console.log statements + unused `memo` import
+
+### What was NOT done / NOT verified
+- Server was NOT restarted after changes
+- Login flow was NOT tested end-to-end by this AI
+- The fix may still fail if there are other API calls in `page.tsx` or child components firing before token check
+
+### IMPORTANT NOTE FOR NEXT AI
+The `page.tsx` file has pre-existing TypeScript errors (not introduced by this session):
+- Line 241: `Property 'serial_number' does not exist on type 'Item'`
+- Line 598-599: `Property 'type' does not exist on type 'Partial<Item>'`
+These are separate issues — do NOT conflate them with the login fix.
