-# Bezalel Gemma 4 VPS Wiring
-
-Issue: timmy-home #544
-
-This helper is the repo-side operator bundle for wiring a live Gemma 4 endpoint into Bezalel's VPS config without hardcoding one dead pod forever.
-
-What `scripts/bezalel_gemma4_vps.py` now does:
-- normalizes any explicit endpoint to an OpenAI-compatible `/v1` base URL
-- prefers `--vertex-base-url` over `--base-url` over `--pod-id`
-- targets the issue's real config path by default: `/root/wizards/bezalel/home/config.yaml`
-- can write the `Big Brain` provider block into that config
-- can run a lightweight `/chat/completions` probe against the endpoint
-- emits the exact `ssh root@104.131.15.18 ... curl ...` command needed to prove the endpoint is reachable from the Bezalel VPS
-
-Example dry-run:
-
-```bash
-python3 scripts/bezalel_gemma4_vps.py \
-  --base-url https://<pod-id>-11434.proxy.runpod.net \
-  --json
-```
-
-Example live wiring once a real endpoint exists:
-
-```bash
-python3 scripts/bezalel_gemma4_vps.py \
-  --base-url https://<pod-id>-11434.proxy.runpod.net \
-  --config-path /root/wizards/bezalel/home/config.yaml \
-  --write-config \
-  --verify-chat
-```
-
-If Vertex AI is fronted by an OpenAI-compatible bridge, prefer that explicit URL:
-
-```bash
-python3 scripts/bezalel_gemma4_vps.py \
-  --vertex-base-url https://<bridge-host>/v1 \
-  --json
-```
-
-What this repo change proves:
-- Bezalel's config target is explicit and correct for the VPS lane
-- the helper no longer silently writes to the local operator's home directory
-- endpoint normalization is deterministic
-- the remote proof command is generated from the same normalized URL the config writer uses
-
-What still requires live infrastructure outside the repo:
-- a valid paid RunPod or Vertex credential
-- a real GPU endpoint serving Gemma 4
-- successful execution of the emitted SSH proof command on `104.131.15.18`
-- successful Bezalel Hermes chat against that live endpoint
