DeepSeek Harness (dsh) Adapter

This crate owns the static, runtime-free projection of DeepSeek Harness (dsh) plugin package sources. It reads a OpenBitFun-managed package whose openbitfun.plugin.json declares adapter: "dsh_compatible", parses the package's package.json dsh declaration, and projects the discovered bundle entries (dsh.bundle.patch -> cordis.patch.yml rows) and/or profile bundle references (dsh.profile.bundles) as projection-only plugin sources.

It does not execute Cordis plugins, install npm packages, or depend on a user-local dsh CLI. Execution of dsh bundles belongs to future Plugin Host / external-ACP work, not this adapter boundary.

If executable dsh support is added, the dsh adapter may project capabilities whose OpenBitFun owner semantics have been verified through the provider-neutral plugin capability contract. Cordis source parsing, execution handles, Host protocol, and lifecycle remain dsh-owned and must not reuse the OpenCode Config Hook or OpenCode Plugin Host composition path. The current configured Skill-root merge and precedence behavior remains OpenCode-owned; dsh Skill publication requires its own consumer evidence before that path is shared.

Boundary Rules

• Depend on stable contracts (openbitfun-runtime-ports, openbitfun-product-domains) and the PluginRuntimeAdapter boundary trait. Do not depend on openbitfun-core, app crates, Tauri APIs, product UI, or concrete service managers.
• Keep the dsh package.json dsh field shape and cordis.patch.yml entry extraction inside this crate. Cross-crate outputs use typed PluginSourceRef / PluginStatusSnapshot / PluginDiagnostic DTOs; do not expose raw dsh YAML or JSON as product contracts.
• Cordis rows may mount services that register model-facing tools when dsh runs them, but static row metadata is not an executable OpenBitFun provider candidate. load_dsh_package_adapter therefore returns no provider dispatch targets. Unsupported or unparsable content must produce typed invalid projections and diagnostics, never silent success.
• New ecosystems are sibling adapters registered by Product Assembly (openbitfun-core/plugin_runtime), not modes of this adapter.

Verification

• cargo test --locked -p openbitfun-dsh-adapter --test dsh_source_adapter
• cargo test --locked -p openbitfun-core --no-default-features --features plugin-runtime --lib plugin_runtime::tests
