     - Caddy 2.10.2 reverse proxy with auto-SSL (Let's Encrypt)
     - Temporary firewall rules removed (ports 3000, 8001)
     - Gitea Actions runner v0.2.13 registered and running as systemd service
+    - SSH key added to Gitea for local push via SSH
+    - Git remote updated: `ssh://git@git.wizard.lu:2222/sboulahtit/orion.git`
+    - CI ruff (lint) job passing
+    - ProxyHeadersMiddleware added for correct HTTPS behind Caddy
+    - Fixed TierLimitExceededException import and Pydantic @field_validator bugs
+    - `wizard.lu` serving frontend with CSS over HTTPS (mixed content fixed)
 
-    **Remaining:**
+    - `/merchants` and `/admin` redirect fix (CMS catch-all was intercepting)
 
-    - [ ] DNS A records for additional platform domains (`oms.lu`, `loyaltyplus.lu`)
+    **Remaining for next session:**
+
+    - [ ] CI pytest job — fails due to pydantic version mismatch (requirements need pinning)
+    - [ ] DNS A records for platform domains (`oms.lu`, `loyaltyplus.lu`)
     - [ ] Uncomment platform domains in Caddyfile after DNS propagation
     - [ ] AAAA (IPv6) records for all domains
     - [ ] Update `platforms` table `domain` column to match production domains
-    - [ ] Verify CI pipeline runs successfully on push
