• Notebook and Compute evidence is deduplicated with verified digests, reducing repeated content in long .science exports. The first export also prepares older evidence. Research packages.
• Modal and Hugging Face connections prepare a compatible Python runtime before browser sign-in and use the system proxy for account checks. Compute accounts.
• Research-film generation continues after switching sessions. Research films.
• Opening mobile pairing leaves access off until you choose WiFi or Internet. Mobile connection.
• Notebook attachments and local file links open previews again. PDF recovery, translation isolation, literature identifiers and narrow source previews receive fixes.
• Idle interpreters are reclaimed after 15 minutes without session activity. Windows update recovery better identifies blocking files/processes, and Linux recovery avoids treating confirmed kernel threads as leaked Notebook processes.
