Semantic resolutions beyond line merges: - The bash seam keeps resolveMode + the bash/resolve-mode waterfall on master's task-free BashExecutor (run/start/resolve only; BashProcess handles); tool-bash consults it at its stamping site and escalation baseline on master's render/background split, with a waterfall test on the recording executor. - dsh-mode's BASH_FAMILY narrows to ['bash']: bash_output/bash_kill are replaced by the kind-generic task_output/task_kill, which span every task kind and only observe or stop work, so the access cap withholds only the starter it can reason about. - The plan-mode snapshot suite adopts master's pin grammar (tool-schema sidecars; the expectedHeaderSnapshots extension is gone — the exit transition deltas, and entering-before-turn-1 needs no second snapshot); modes-advertise joins the plan header class (no-model, so membership is vacuous). Fixtures re-recorded on the acp-demo bin; the replay overlay gains the passthrough sandbox runner. - examples/plan-acp-agent rewires to @deepseek-ai/dsh-acp-demo and drops its tool-bash entry (the spine bundle now composes it); dsh-stdio (the renamed stdio-chat home) keeps its /mode command and gains the dsh-mode peer edge; the acp bridge keeps the modes surface beside master's permission presets. - mode README gains the Model Experience / Known Limitations sections the new README gates require; AGENTS.md ceiling 1370 → 1440 for the kept mode/ layout line and Agent efficiency section.
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.
