Treat an absolute path.relative() result as a cross-volume path instead of incorrectly abbreviating it beneath the user's home directory. Allow embeddings to project a logical footer cwd without changing the operational session cwd. The recorded-session harness now uses a POSIX-shaped display alias for both the footer and filesystem result paths, preserving the existing pre-normalization layout width on every host. Keep runtime-provided labels behind terminal-control escaping, cover that boundary, and document the embedding contract.
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/ |
Line-oriented terminal channel for pipes and automation; drives ctx.agents, renders session/event, and answers ctx.userInteraction |
(drives ctx.agents) |
tui/ |
Interactive pi-tui terminal channel for TTY sessions; renders session/event, tool presentation intents, and answers ctx.userInteraction |
(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 and tui plugins are the two terminal front doors: one is line-oriented for pipes, the other is interactive for TTYs. App bundles and SDK projects compose the appropriate channel 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 terminal 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.
