Two new PR-time gates that the existing inference / wheel jobs miss.
Studio Update CI:
- Runs install.sh --local --no-torch, then `unsloth studio update
--local` twice, asserting both invocations take the prebuilt
"up to date and validated" code path with no source-build
fallback.
- Boots Studio to /api/health afterwards so a broken update that
nukes the venv or the llama-server binary surfaces immediately.
- Triggers when install.sh, studio/setup.sh, the python_stack /
llama_prebuilt installers, the requirements files, or
unsloth_cli/commands/studio.py change.
Studio UI CI:
- Drives the actual frontend bundle in headless Chromium via
Playwright with the smallest GGUF (gemma-3-270m-it UD-Q4_K_XL).
- Covers: bootstrap login, must_change_password gate + change form,
chat composer becomes interactive after model load, sending a
message produces an assistant bubble with non-empty text, full
page reload re-hydrates the conversation, configuration sheet
opens and closes cleanly, and the rotated password is the only
one that logs in afterwards.
- This is the first workflow that catches the class of bug 2026.5.1
shipped: backend healthy + frontend builds, but assistant-ui
runtime wiring or chat-history persistence broken so the actual
UI was unusable. Backend-only or wheel-only gates do not see it.
