## Rules
|
||
|
|
|
||
|
|
1. **Do not change** these IPs in config, scripts, or documentation.
|
||
|
|
2. **Source of truth:** `config/ip-addresses.conf`
|
||
|
|
3. **Scripts:** Use `scripts/lib/vmid-ip-maps.sh` or source `config/ip-addresses.conf`.
|
||
|
|
4. **Verification:** `scripts/verify/verify-backend-vms.sh` expects these fixed IPs.
