The composer seat spent nearly all its life disabled: a session's composition is fixed once a turn has run. Move the choice to the new-session screen beside the workspace picker, where it still works, and let the session header report what a running session runs. The hero pick is staged rather than applied — that screen precedes the session it belongs to. It lands when a session becomes current and is still blank, which covers both the session a workspace connect creates and the blank one it reuses; riding `sessions.create` would miss the second. It is spent on first use, matching the workspace picker. Fix the durability the header field claimed but never had: `agentPreset` was declared on `SessionHeader` and dropped by the JSONL header line, the SQLite sessions row, the derived query index, and the cold list projection, so every resumed session came back composed from nothing. Add the web e2e lane that would have caught it — the one lane that mounts the shipped roster, which needed `cordis:group` in the scaffold's Loader builtins, as `mountRootInclude` already registers.
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.

New packages join existing groups; new groups update their 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.
