Importing Codex or Claude Sessions into DeepSeek Harness (DSH)

The `dsh-assembly.resume` plugin is designed to enable seamless migration of Codex or Claude Code sessions to DSH. It provides core capabilities such as session lookup and grouping, importing the complete context (including tool activity), and automatic Workspace registration. Developers can install and configure the plugin by specifying a Profile, then continue processing historical sessions within the DSH Agent environment, avoiding context loss. It is suitable for development scenarios that require integrating sessions from external tools.
