**Motivations:**
- Ollama and AnythingLLM moved from 192.168.1.164 to the ia LAN host.
**Root causes:**
- Upstreams still targeted 192.168.1.164.
**Correctifs:**
- Set upstream servers to 192.168.1.173:11434 and :3001.
**Evolutions:**
- Docs aligned with ia role IP; note to edit site conf if IP changes.
**Pages affectées:**
- deploy/nginx/sites/ia.enso.4nkweb.com.conf
- deploy/nginx/README-ia-enso.md
- docs/features/ia-enso-nginx-proxy-ollama-anythingllm.md
- docs/infrastructure.md
- docs/services.md
**Motivations:**
- split script failed after subtree split when optional root files (e.g. .dockerignore) were missing on branch test
**Root causes:**
- git add with a missing path in the list fails entirely and stages nothing; git commit then fails under set -e
**Correctifs:**
- add each copied file only if it exists in the deploy repo; skip commit if index empty
**Evolutions:**
- none
**Pages affectées:**
- setup/split-lecoffre-ng-to-five-repos.sh
