 Root authorized one normal portable QEMU TCG boot, one CPU/1536 MiB, five-minute monotonic cap, preserving 15 GiB host free disk. Prepared .local/linux-host-ytr83r/{prepare,pilot}.cjs pass Node syntax checks; pilot --describe passed. Report gives exact curl -4 --continue-at - resume, checksum fetch, preparation and hidden launch commands. prepare.cjs verifies both publisher checksums and creates a new 12 GiB sparse overlay/private UEFI vars/disposable SSH seed only when the whole image is present. Pilot uses normal Q35/UEFI, no direct kernel/no_timer_check workaround; loopback-only 18080/2222/4445, ACPI powerdown at 270s, owned-child stop at 300s. No automatic retry of an existing pilot result.

+Root authorized a three-MiB protocol diagnosis: HTTPS two 1MiB ranges averaged 507.37 KiB/s; HTTP was 134.59 KiB/s. All three HTTP206 responses exactly matched retained overlap bytes. No separately documented official CDN for this exact pinned image was established. This small-sample result justified a separately authorized resume with 600s maximum and 128KiB/s for30s low-speed stop, not another identical900s attempt.

Curl reports1,228,800 received bytes in31.686317s, 38,780 bytes/s. Latest retained partial size is12,943,360 bytes. No full publisher checksum verification, guest seed/overlay, VM/boot, apt or Cargo occurred; no retry followed. No settings, security, network or timer/kernel workaround changed.
