     * Migrates accordion blocks from snl-blocks/snl-accordion to snl/accordion-wrapper
     *
     * ## OPTIONS
     *
     * [--dry-run]
     * : Run the migration without making any changes (preview only)
     *
     * [--post-type=<post_type>]
     * : Limit migration to specific post type (default: page,post)
     *
     * [--blog-id=<blog_id>]
     * : Specific blog ID to migrate (use 'all' for all sites, defaults to main site)
     *
     * [--batch-size=<size>]
     * : Number of posts to process per batch (default: 50)
     *
     * [--start-batch=<number>]
     * : Resume from a specific batch number (default: 1)
     *
     * [--show-urls]
     * : Display the URL of each page as it's migrated, including skipped posts
     *
     * [--post-id=<id>]
     * : Test migration on a specific post ID only
     *
     * [--debug]
     * : Output raw block attributes for debugging attribute mapping
     *
     * ## EXAMPLES
     *
     *     # Preview changes without applying them
     *     wp accordion-migrate run --dry-run
     *
     *     # Test on a specific post
     *     wp accordion-migrate run --post-id=123 --dry-run
     *
     *     # Debug attribute keys on a specific post
     *     wp accordion-migrate run --post-id=123 --dry-run --debug
     *
     *     # Run the actual migration
     *     wp accordion-migrate run
     *
     *     # Migrate specific blog
     *     wp accordion-migrate run --blog-id=2
     *
     *     # Migrate all sites in network
     *     wp accordion-migrate run --blog-id=all
     *
     *     # Use smaller batch size
     *     wp accordion-migrate run --batch-size=25
     *
     *     # Resume from batch 3
     *     wp accordion-migrate run --start-batch=3

                <p>This report summarizes the activities performed as part of the Science and Engineering of Cybersecurity by Uncertainty quantification and Rigorous Experimentation (SECURE) Grand Challenge LDRD project. We provide an overview of the research done in this project, including work on cyber emulation, uncertainty quantification, and optimization. We present examples of integrated analyses performed on two case studies: a network scanning/detection study and a malware command and control study. We highlight the importance of experimental workflows and list references of papers and presentations developed under this project. We outline lessons learned and suggestions for future work.</p>

                <p>The object of the 'Enabling Immersive Simulation for Complex Systems Analysis and Training' LDRD has been to research, design, and engineer a capability to develop simulations which (1) provide a rich, immersive interface for participation by real humans (exploiting existing high-performance game-engine technology wherever possible), and (2) can leverage Sandia's substantial investment in high-fidelity physical and cognitive models implemented in the Umbra simulation framework. We report here on these efforts. First, we describe the integration of Sandia's Umbra modular simulation framework with the open-source Delta3D game engine. Next, we report on Umbra's integration with Sandia's Cognitive Foundry, specifically to provide for learning behaviors for 'virtual teammates' directly from observed human behavior. Finally, we describe the integration of Delta3D with the ABL behavior engine, and report on research into establishing the theoretical framework that will be required to make use of tools like ABL to scale up to increasingly rich and realistic virtual characters.</p>

                <p>This 3-year research and development effort focused on what we believe is a significant technical gap in existing modeling and simulation capabilities: the representation of plausible human cognition and behaviors within a dynamic, simulated environment. Specifically, the intent of the ''Simulating Human Behavior for National Security Human Interactions'' project was to demonstrate initial simulated human modeling capability that realistically represents intra- and inter-group interaction behaviors between simulated humans and human-controlled avatars as they respond to their environment. Significant process was made towards simulating human behaviors through the development of a framework that produces realistic characteristics and movement. The simulated humans were created from models designed to be psychologically plausible by being based on robust psychological research and theory. Progress was also made towards enhancing Sandia National Laboratories existing cognitive models to support culturally plausible behaviors that are important in representing group interactions. These models were implemented in the modular, interoperable, and commercially supported Umbra{reg_sign} simulation framework.</p>
