Records the 2026-09-29 drill: offsite restic snapshot restored on the laptop, restore-drill checks all ok (69 repositories, 529 release assets, 2 LFS objects), host key matches, service in 8m43s without host provisioning. Secrets were not checked (no secret.key copy on the drill machine); #305 tracks that, and replaces #259 in Known-Gaps. Architecture 08/09/10 updated.
Closes #259
