### [Horus] — 2026-04-10
**Mistake:** Assumed council.sitemente.com pointed to Horus — it pointed to Hostinger.
**What happened:** Claw3D couldn't reach gateway, spent 30 min debugging DNS that was already wrong.
**What I learned:** Always verify DNS with `dig +short` before assuming infrastructure topology.
**Fix applied:** Check actual DNS resolution before troubleshooting connectivity.

### [Horus] — 2026-04-10
**Mistake:** Tried to use `nginx` command — binary was at `/usr/sbin/nginx`.
**What happened:** nginx installed but not in PATH, `which nginx` returned nothing.
**What I learned:** Ubuntu nginx package installs to /usr/sbin, not /usr/bin.
**Fix applied:** Use `/usr/sbin/nginx` directly.

### [Amun] — 2026-04-09
**Mistake:** Ollama override directory didn't exist.
**What happened:** `/etc/systemd/system/ollama.service.d/override.conf` — dir missing.
**What I learned:** Must `mkdir -p /etc/systemd/system/ollama.service.d` before creating override.
**Fix applied:** Always create directory structure first.
