The server-proxied upload flow (replaces presign-PUT) stores the file-level metadata directly on the UploadSessions row at session creation, so step 2 (PUT bytes) can build the StorageObjects row without re-sending metadata through a separate CompleteUploadRequest. New columns on upload_sessions: file_name VARCHAR(255) NOT NULL DEFAULT '' usage_type VARCHAR(32) NOT NULL DEFAULT 'working_copy' visibility VARCHAR(16) NOT NULL DEFAULT 'private' is_immutable TINYINT(1) NOT NULL DEFAULT 0 The SQLAlchemy model already declares these columns; this migration applies the schema change to MySQL. Migration: c3d4e5f6a7b8_upload_session_object_metadata.py (chains off a2b3c4d5e6f7)
