The AdaptiveContextPlane (ACP) Plugin for DeepSeek Harness (dsh): A Governed Long-Term Memory System

The `dsh-adaptive-context` (ACP) plugin is designed to address long-term memory management pain points for agents in the DSH ecosystem. It transforms memory management into an “auditable ledger” through features such as a SQLite evidence ledger, write and read gates, user permission controls, and context orchestration, ensuring that memories are authoritative, accurate, and traceable. The plugin supports multi-source routing, style promotion, temporal truth queries, and audit export, enabling a complete record of the evolution of user preferences and corrections. Installation requires adding the plugin via the CLI and configuring an explicit data directory, after which a restart is required for the changes to take effect. It provides a standardized memory governance solution for long-running agents with high consistency requirements.
