/tmp is wiped when this machine reboots. On 2026-10-09 a reboot mid-task erased every helper script, render and review note of the tri-vi-portfolio 3D house work, and they had to be rewritten.

**Why:** the box reboots without warning (kernel updates), and sessions get cut.

**How to apply:** put anything that must outlive the session outside both /tmp and the repo. The tri-vi house pipeline lives in `~/.cache/tri-vi-bake/` (bpy venv, scripts/, out/, study.glb). Keep running notes there too, not only in context. Related: [[agenthub-server-box-hardware]].
