dsh-workstate: Verifiable Work State Checkpoints and Secure Handover for DeepSeek Harness

# Introduction When using an AI coding agent to run long tasks, a common situation arises where the task needs to be paused halfway through, or the context needs to be handed over to another agent or developer for continuation. The standard handoff method involves simply passing along chat logs or work notes. The recipient receives descriptive text that requires manual reconstruction to understand exactly which step the task is on, which decisions have been made, and which validations have passed. Furthermore, it is impossible to confirm whether the workspace is still in the same state as it was at the time of handoff. dsh-workstate solves exactly this problem. It captures the agent's current work into a machine-readable state package. Before resuming, it first validates whether the workspace still matches, and then injects the state. # What is dsh-workstate? dsh-workstate is designed for...
