## 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

- Auth via local gitignored `.build-token` matching Worker secret `BUILD_TOKEN` (value not recorded here).
- HTTP 200 in ~49s for initrd-only; ~94s for ISO (kernel fetch + grub-mkrescue in Sandbox).
- Staged sandbox path worked (no edge 1101 on these runs).
- Not metal. Not non-x86_64. Not proof of every future CF build (infrastructure residual can recur).
- Git **remote unset** on this clone — push residual remains (nothing to push to without user remote URL).
