 ## 10. Record
 
+- 3.22.1: triton beside the testbed's CPU torch on Linux (2026-10-17, found by image-creator-krea-2#10). The CPU torch
+  that 3.18.2 gave the testbed has no triton, which a pod's CUDA torch carries (`lib/30-venv.sh` keeps it in the torch
+  family), and packs import it at module level: ComfyUI-RMBG's HEAD (229529e) bundles a sam3 whose `edt.py` does
+  `import triton`, the pack's loader then raises a NameError in its own except branch and none of its nodes register,
+  and ComfyUI-Easy-Sam3 stops on `No module named 'triton'`. Every package that uses RMBG saw a missing node on CI.
+  `testbed.sh --server` on Linux now installs the newest triton right after torch, against a constraints file of the
+  torch family as installed (`testbed/.testbed-torch.txt`), so it never moves torch; importing it needs no GPU. A miss is
+  a warning and the build goes on. `--status` names the venv's triton on Linux, and, for every package, the packs its own
+  server could not import: each pack ComfyUI's "Import times for custom nodes" marks `(IMPORT FAILED)` in that server's
+  log, or "none". Krea 2's CI (run 39078526395) had passed its suite while RMBG never registered, with nothing in the
+  log to say so. macOS (no triton wheels) and the pod's install are unchanged. Unit tests hold the order, the
+  constraints, the warning, the macOS path, and the import report (a failed pack named, a clean one not, "none", a
+  foreign server never read). Exercised on the CI runner only.
 - 3.22.0: install speed on the critical path, and a clock that shows it (Paul's priority 3, 2026-10-17). Read from the
   last Video Replacer pod (1x B200, EU-RO-1, base 3.20.0, every row: 42 files, 295.5 GB): about 5:17 from create to the
