• source_sqsh -> apps-2026-11-10.sqsh: rebuilt archive with the fixed R kernel launcher and the R 4.5.2 / Python 3.14 kernel specs. Already in the bucket. Both kernels verified from the mounted archive on the build VM.
• image -> jupyterlab-generic:feat_software-library-kernels (jupyterlab-generic: discover software-library kernels via JUPYTER_PATH, add GEN3_DISABLED_KERNELS containers#375): that branch adds JUPYTER_PATH=/apps/jupyter so JupyterLab finds the kernels. heal-notebooks:software_library_heal is still built on generic 3.4.0 and can't see them, so this is temporary until jupyterlab-generic: discover software-library kernels via JUPYTER_PATH, add GEN3_DISABLED_KERNELS containers#375 is released and the HEAL Dockerfile is bumped.
• Removed --LabApp.default_url=/lab/tree/heal-welcome-wsl.ipynb: that notebookb is copied in by the heal-notebooks Dockerfile and doesn't exist in the generic image, so Lab would open to a "could not find path" error. Restore it together with the image when switching back to heal-notebooks.
