## Recent decisions
- `[2026-10-02]` **nh3-dev root grown 250 → 378 GB (Prime resized scsi0; I grew the guest online, no reboot).** Root 372 GB, 58%, 150 GB free, after the 85% alert fired twice in 14 h (uv cache + agent venvs). Swap moved to a 4 GB `/swapfile` (the old `sda5` blocked growth), `RESUME=none`, all initrds rebuilt (`playbooks/nh3-dev-grow-root.yaml`). ⚠ **TODO: delete VM snapshot `pre-rootgrow-20261002` on nh3-pve after the next clean reboot** (it pins ZFS space as the disk churns).
- `[2026-10-02]` **nh3-dev root grown 250 → 378 GB (Prime resized scsi0; I grew the guest online, no reboot).** Root 372 GB, 58%, 150 GB free, after the 85% alert fired twice in 14 h (uv cache + agent venvs). Swap moved to a 4 GB `/swapfile` (the old `sda5` blocked growth), `RESUME=none`, all initrds rebuilt (`playbooks/nh3-dev-grow-root.yaml`). ⚠ **TODO: delete VM snapshot `pre-rootgrow-20261002` on nh3-pve after the next NATURAL reboot (Prime 2026-10-02: no test reboot).** Trigger: `uptime -s` on nh3-dev later than 2026-10-02 0733. Then check the boot was clean (`swapon --show` = /swapfile; `systemd-analyze` shows no ~30 s stall; `journalctl -b | grep -i resume` has no 'waiting for resume device'), and only then `qm delsnapshot 102 pre-rootgrow-20261002`.
- `[2026-10-01]` **MIA (Make-It-Animatable v2) auto-rigger LIVE on fv-ml1 GPU 3, one-shot (Prime via dread-dev).** `scripts/mia-run --job DIR -- name=in.glb ...`, image `local/mia:0.1.0` (10.5 GB), weights in the shared HF cache at pinned revisions (sha256-verified). Acceptance: 3.9–4.7 s a mesh (median of 3), 12.7 s model load, peak 3,394 MiB; seeded runs bit-identical; GPU-vs-CPU distances the same size as sampling noise (positive control: unseeded GPU). Skeleton template is a SUBSTITUTE (gated HF dataset `jasongzy/Mixamo`, terms not accepted; Prime's call). ⚠ fv-ml1 zroot at 85% after the build. → `stacks/mia/README.md`
- `[2026-10-01]` **Prime: "clean up the 1700+ backups" — dev-backup retention FIXED, 1,740 husks removed.** They were never 1,788 real snapshots: the prune had deleted everything except one 0555 dir (`vastblue/praxis/references/PraxisPM_Rev0_07.11.26`, 17 files hardlinked into every snapshot), so each old dir was a 22-entry husk and only the newest 48 were complete. Removing them lost no history and freed ~0 bytes (same inodes, link count 1,788). Deletion ran from a generated list of 1,740 literal paths, each verified as a husk first, with 0 errors. The script now runs `chmod -R u+w` before `rm`, logs the error count and the kept count, and fails the unit (exit 3) on a bad prune or exit 1 on a failed rsync. Positive control: a manual run at 0556 pruned the full snapshot `2026-09-29_0602` with 0 errors, leaving 48. Retention stays the designed 48 hourly; the 4.6 GB log rotated at 0530 is kept, compressed to 99 MB, at `~/.config/dev-backup/dev-backup.log.20261001-0530.gz` until someone deletes it.
- `[2026-10-01]` **Prime: gen-small keeps its 8 GiB KV pin, and parakeet-nemo keeps CUDA graphs OFF** (~2–8 ms at short clips, accepted). GPU 0's ~1 GB of spare memory is enough with the seat's hard 3,840 MiB cap.
