Replace the full-innerHTML render loop with a static shell plus per-region updates, so composer drafts, fold state, focus, and scroll survive streaming turns. Fold session events into one trace graph consumed by Chat, Trajectory, Waterfall, and the shared inspector drawer, with live ACP updates patched into a keyed live-turn region. Align the visual system with a tokenized design spec: a 4px spacing base with fixed control/row height steps, foreground-derived text tiers and borders (color-mix), neutral interaction overlays, tiered motion durations with a reduced-motion collapse, hover-revealed scrollbars, and drawer-aware layout elasticity. Localize trajectory role chips and row previews. The renderer entry (app.ts) joins the coverage exclude list as a self-executing DOM bootstrap: jsdom lifecycle specs exercise its behavior, and extractable logic lives in covered modules (trace-graph.ts, renderer-content.ts).
ui/ — editor/client integration surfaces
Integrations that expose the agent to an external editor or client. These are product packages: a real surface a user drives the harness through.
| Package | Role | ctx key |
|---|---|---|
acp/ |
Agent Client Protocol bridge: serves the agent to an ACP editor (Zed) over JSON-RPC stdio | (drives ctx.agents/ctx.sessions) |
user-approval/ |
One-shot user-approval mechanism, closed outcome vocabulary, audit events, and per-session approval policy | ctx.approval |
permission/ |
User-facing permission presets (workspace-write/danger-full-access): one product-level select bundling the sandbox-mode and approval-policy knobs, written through to their session events |
ctx.permission |
user-interaction/ |
Abstract human question/answer seam used by UI-backed confirmation tools | ctx.userInteraction |
tool-ask-user/ |
Model-facing ask_user_question tool over ctx.userInteraction |
(registers on ctx.tools) |
stdio/ |
Terminal readline channel over ctx.agents, session/event, and ctx.userInteraction; agent lifecycle stays with app/developer code |
(drives ctx.agents) |
jsonrpc/ |
Stdio JSON-RPC server for out-of-process SDK clients | (drives ctx.agents) |
app-boot/ |
Shared boot glue for the app bins: .env loading, fail-loud Loader guards, snapshot-aware config resolution, the settle-the-tree boot sequence |
(library for the bins) |
A UI integration is a client-driver plugin, not a loop change and not a capability seam: it consumes the existing agent/* event taxonomy and the dsh-agent factory. The jsonrpc plugin is the SDK-client sibling of the acp bridge (a JSON-RPC server over ctx.agents for out-of-process SDK clients rather than editors). The stdio plugin is the unstructured readline analogue of the acp bridge; app bundles and SDK projects compose it explicitly with the services and tools their product profile selects.
user-approval, user-interaction, and tool-ask-user live here because asking a human is a UI-backed product affordance, not part of the providerless core spine. user-approval owns the one-shot ctx.approval decision mechanism and its policy tier; answerers remain with their UI channel owners. user-interaction remains provider-neutral (ctx.userInteraction), while tool-ask-user is its model-facing consumer and the app/bridge packages provide concrete providers.
The runnable app bundles that bake these bridges into boot bins — the stdio chat app, the ACP server app, and the JSON-RPC SDK-runtime bin — live in examples/ (stdio-demo, acp-demo, jsonrpc-demo), each composed over the agent-spine-demo bundle. ui/ keeps the reusable bridge/channel plugins and the app-boot glue; each front door owns its stdout policy, and a leaf cordis.yml supplies backends and optional tools.
