DSH-CAD-Review: ASCII DXF Inspection and Deterministic Rule Review for DeepSeek Harness

dsh-cad-review is an MIT-licensed plugin within the DeepSeek Harness ecosystem, designed specifically for entity-level deterministic review of ASCII DXF files. It abandons screenshot-based empirical inference and directly reads CAD entities, hashing source files and linking issues to entity handles, layers, source code lines, and geometric positions to ensure results are reproducible and evidence-backed. The plugin supports common geometry types such as LINE and CIRCLE, offering two core functions: `inspect` (evidence-only checking) and `review` (policy-based rule execution), with rules covering invalid values, zero-length lines, layer restrictions, and duplicate entities. It can be invoked via CLI, DSH tools, or the MCP interface, and supports configuring project-specific policies to override default rules. If the review identifies error-level issues, the system returns a specific exit
