## Verbatim `numos:` lines

```
numos: arch x86_64
numos: init numinit.sh (shell floor)
numos: on-disk /opt/numericalos/numinit.sh
numos: state verified
numos: boot complete degraded=0
numos: steady state entered
```

## Notes

- Not metal. Not ISO/GRUB chain. Not non-x86_64.
- Fleet profile remains PASS-degraded on bare QEMU (separate observation).
- Floor implementation binary is multi-call static resolved via graph; product name is `numos-floor`.
