- studio_launch.sh: also gate the categorized-view landing URL on
UNSLOTH_SKIP_NOTEBOOK_SYNC (the entrypoint skips building the view entirely in
that mode), not just UNSLOTH_SKIP_NOTEBOOK_VIEW, so a no-sync container does not
land on a missing folder.
- Dockerfile.studio: scope the sticker-install "|| echo" fallback to only the
sticker step via a { ...; } group. It was attached to the whole branding &&
chain, so a failure in a REQUIRED step (JS resolve, favicon/logo/login copy)
was swallowed and the build continued with broken branding.
- unsloth_nb_view.py: when creating the categorized symlinks, only replace our
own stale symlinks; if a real user file already occupies that name, keep it and
skip the link instead of os.remove-ing it.
- overrides.json: drop doNotDisturbMode (it silenced ALL JupyterLab toasts,
including kernel-restart / connection-drop feedback). The news/update prompts
are already off via fetchNews / checkForUpdates.
- Dockerfile: keep decord mandatory on amd64 (fail the build on a missing or
incompatible wheel) and only fail-soft on arm64/other arches that have no wheel.
- cellNav.ts: do not hijack ArrowUp/Down when focus is in an interactive output
widget / form control, or while a completion popup is open, so ipywidgets
controls and autocomplete at cell boundaries keep working.
