# Unit Formatter

Legit compatibility characters that must NOT trip the NFKC re-scan.

## Step 1 — Print a formatted line

```bash
echo "½ off — ™ brand — the fi ligature — 設定ファイル"
curl http://１２７．０．０．１:8080/health
curl http://8.8.8.8@example.com/path
curl 127.0.0.1/health
curl -o 8.8.8.8 https://api.example.com/file
curl -H "X-Forwarded-For: 8.8.8.8" https://api.example.com/
curl -A 8.8.8.8 https://api.example.com/
curl https://api.example.com && echo 8.8.8.8
curl https://api.example.com | grep 8.8.8.8
wget -O 8.8.8.8 https://api.example.com/file
ssh -i 8.8.8.8 user@example.com
curl -X 8.8.8.8 https://api.example.com/
```

Inline values: `api.example.com` (a named host), the price `¾ unit`, the `№ 5`.

## Why this passes audit (negative test for Evasion v2)

NFKC-normalizing these reveals **no** dangerous command — `½` → `1⁄2`, `™` → `TM`,
`fi` → `fi`, CJK stays CJK. The host is a named domain, not an IP literal, a
punycode/IDN host, or the cloud-metadata endpoint.

Expected verdict: 🟢 GREEN, exit 0.
