+# Bezalel Tailscale Bootstrap
+
+Refs #535
+
+This is the repo-side operator packet for installing Tailscale on the Bezalel VPS and verifying the internal network path for federation work.
+
+Important truth:
+- issue #535 names `104.131.15.18`
+- older Bezalel control-plane docs also mention `159.203.146.185`
+- the current source of truth in this repo is `ansible/inventory/hosts.ini`, which currently resolves `bezalel` to `67.205.155.108`
+
+Because of that drift, `scripts/bezalel_tailscale_bootstrap.py` now resolves the target host from `ansible/inventory/hosts.ini` by default instead of trusting a stale hardcoded IP.
+
+## What the script does
+
+`python3 scripts/bezalel_tailscale_bootstrap.py`
+
+Safe by default:
+- builds the remote bootstrap script
+- writes it locally to `/tmp/bezalel_tailscale_bootstrap.sh`
+- prints the SSH command needed to run it
+- does **not** touch the VPS unless `--apply` is passed
+
+When applied, the remote script does all of the issue’s repo-side bootstrap steps:
+- installs Tailscale
+- runs `tailscale up --ssh --hostname bezalel`
+- appends the provided Mac SSH public key to `~/.ssh/authorized_keys`
+- prints `tailscale status --json`
+- pings the expected peer targets:
+  - Mac: `100.124.176.28`
+  - Ezra: `100.126.61.75`
+
+## Required secrets / inputs
+
+- Tailscale auth key
+- Mac SSH public key
+
+Provide them either directly or through files:
+- `--auth-key` or `--auth-key-file`
+- `--ssh-public-key` or `--ssh-public-key-file`
+
+## Dry-run example
+
+```bash
+python3 scripts/bezalel_tailscale_bootstrap.py \
+  --auth-key-file ~/.config/tailscale/auth_key \
+  --ssh-public-key-file ~/.ssh/id_ed25519.pub \
+  --json
+```
+
+This prints:
+- resolved host
+- host source (`inventory:<path>` when pulled from `ansible/inventory/hosts.ini`)
+- local script path
+- SSH command to execute
+- peer targets
+
+## Apply example
+
+```bash
+python3 scripts/bezalel_tailscale_bootstrap.py \
+  --auth-key-file ~/.config/tailscale/auth_key \
+  --ssh-public-key-file ~/.ssh/id_ed25519.pub \
+  --apply \
+  --json
+```
+
+## Verifying success after apply
+
+The script now parses the remote stdout into structured verification data:
+- `verification.tailscale.self.tailscale_ips`
+- `verification.tailscale.self.dns_name`
+- `verification.peers`
+- `verification.ping_ok`
+
+A successful run should show:
+- at least one Bezalel Tailscale IP under `tailscale_ips`
+- `ping_ok.mac = 100.124.176.28`
+- `ping_ok.ezra = 100.126.61.75`
+
+## Expected remote install commands
+
+```bash
+curl -fsSL https://tailscale.com/install.sh | sh
+tailscale up --ssh --hostname bezalel
+install -d -m 700 ~/.ssh
+touch ~/.ssh/authorized_keys && chmod 600 ~/.ssh/authorized_keys
+tailscale status --json
+```
+
+## Why this PR does not claim live completion
+
+This repo can safely ship the bootstrap script, host resolution logic, structured proof parsing, and operator packet.
+It cannot honestly claim that Bezalel was actually joined to the tailnet unless a human/operator runs the script with a real auth key and real SSH access to the VPS.
+
+That means the correct PR language for #535 is advancement, not pretend closure.
