The implementation no longer stores inherited policy in SessionHeader or resolves a second baseline chain, but the feature, sandbox, and approval notes still described that machinery. Keeping those claims would make the smaller design look incomplete and invite reintroduction of the generic persistence surface. Rewrite the owning feature note around the actual delegation snapshot: source-tagged policy events follow the optional fork prefix, ordinary last-event-wins folds establish precedence, and persistence captures the constructor seed with the first materialized batch. Condense the alternatives and consequences to the decisions and coverage that remain load-bearing. Align the sandbox and approval notes plus the subagent-inprocess consumer README with that contract. Update the four Chinese counterparts minimally and re-record each pairing hash so both languages describe the same shipped mechanism.
Packages
English | 中文
Packages use the @deepseek-ai/dsh-* scope. Each is a Cordis Service subclass or function plugin; contributions use ctx.effect(), ctx.on(), or ctx.waterfall(). Authoring rules: package and root.
Hierarchy
Packages live at packages/<group>/<pkg>/; groups are containers, while names remain @deepseek-ai/dsh-<pkg>. Each group README is the canonical package/ctx-key map.

Groups distinguish product API from support infrastructure. New packages join an existing group; a new group updates its README and this table.
Dependencies
The dependency graph is generated: docs/module-graph.md (pnpm run gen-module-graph, freshness-gated in CI).
Extension plugins depend on interfaces, never the concrete loop. dsh-agent-loop is swappable; UI, hook, and tool plugins use dsh-agent. Composition bundles, including dsh-agent-spine-demo, may depend on spine plugins. Capabilities split into interface / implementation / consumer packages; see capability seams.
Package READMEs cover purpose, APIs, extension points, and Model Experience unless on the model-agnostic omission allowlist. They also carry ## Known Limitations and Deferred Work or use its allowlist.
