Four rounds of structural rework on the conversation surface, converging on one registration model for the whole client: - Review fixes: open() leaves the inject factory (SessionsService owns the semantic); ConversationService mounts via ctx.plugin(); the bespoke view registry retires into the 'conversation.view' list slot. - Ring alignment: createChatView factory retired (components get everything through checkable shares at the register call site); the hand-rolled t/i18n threading is deleted wholesale — a future framework-level i18n will supply t as a standard prop keyed by slot name, so no interim manual channel. - Toolview dissolution: ToolViewRegistry / ToolViewResolver / ToolViewOutlet / ctx.toolviews retire. Tool rows are entries of the 'conversation.chat.toolview' keyed slot (scope: session) declared by the chat entry; ToolRowOwnerProps is the unified owner payload; GenericToolCard becomes the call-site fallback; registrants are plain plugins (inject ['slots','conversation'] as the load-order seam); session-dimension dispatch moves into components (useSessions reads parentId); trajectory/waterfall gain same-shape slots the day they render tool rows (RendersCheck rejects empty declarations). Slot names mirror the composition path (<domain>.<entry>.<hole>). - Staging follows current: cell()/binding() are pure resolution (render-safe); the constructor subscribes to the list store and followCurrent opens the event window when the current session changes — staging IS the open signal, business verbs are the timing, React render/commit is decoupled from window lifecycle. A masked current (projection gap) keeps the stage untouched so deferred teardown semantics survive reconnects. Agent Note: .agents/notes/implemented/architecture/ 2026-07-23-toolview-dissolution.md (bilingual pair) records the decision, the four rejected alternatives, and the accepted semantic changes; the web client architecture note and packages/client/AGENTS.md carry the current-state narrative. Verified: typecheck 0, duplication 0 clones (478 files), full coverage run 6190 passed with zero threshold errors, knip 0, doc-sync 24/24, client aggregate tsc 0, render-count checks (one commit per chunk, zero row re-renders under streaming) green.
Packages
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.
