v0.3.10

Breaking Changes

• osmosis eval upload and eval run --upload now use archive imports instead of individual file uploads, with no per-file upload fallback (#466).
• Direct eval-import integrations must replace files= with archive= in OsmosisClient.start_eval_run_import(), upload files.jsonl and run.zip, and wait for extraction to reach ready using start_eval_run_import_extraction() and get_eval_run_import_extraction() before finalizing (#466).
• Eval-import results require upload_mode, list upload slots in files for archive imports, and allow slot sha256 values to be None; update model constructors and result handling accordingly (#466).

Changed

• Local eval uploads stream a ZIP64 archive one part at a time without writing a temporary archive to disk, replacing per-file requests and skipping completed upload slots on retry (#466).

Fixed

• Strands rollouts preserve earlier assistant reasoning in follow-up requests, live previews, and ATIF trajectories instead of dropping reasoning_content (#465).
