Turtle 007e8fd92f refactor(cli): bail early in the arg adapter instead of returning errors as data
Address review and cut ceremony: the adapter no longer models help/version/
errors as DshInvocation members. Commander owns those under exitOverride — it
prints usage or the diagnostic and one try/catch in parseDshArgs turns the
thrown CommanderError into process.exit with the intended code. bin.ts drops its
help/version/error cases; the union is the three real modes.

Domain checks bail via command.error(print + exit 1): --prompt rejects an empty
task or a stray config/--resume, empty --resume= fails loud, and --host/--port
are validated. A repeated --resume or a flag captured as a value is Commander's
standard behavior, left alone (a bad id fails loud downstream). dsh --help
discloses web via addHelpText. Net: args.ts 185 -> 112 lines.

Also fixes review nits: built-bin e2e resolves on `close`; the /resume handoff
uses `dsh --resume=<id> -- <config>` so a config named `web` stays a positional;
and stale prose (cordis.yml comment, app-boot module doc + duplicate JSDoc,
ui/README, two feature notes, an agent-loop test name) tracks the shipped state.
Removes tui-demo's now-dead plugin-include dep and vendor/loader + app-boot
tsconfig references.

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 agents, commands, and live/replayed title updates to an ACP editor over JSON-RPC stdio (drives ctx.agents/ctx.sessions)
commands/ Human-command registry: shared discovery metadata, scoped shadowing, cancellation, and direct UI dispatch ctx.commands
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)
tui/ Interactive pi-tui terminal channel; renders session titles/events and tool intents, answers ctx.userInteraction, and hosts effect-owned plugin overlays ctx.tui (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: 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). tui is the interactive terminal front door and supplies the terminal-local ctx.tui extension service; non-interactive tasks use the headless cli-demo app instead of a UI channel. commands is the human-only discovery and dispatch plane shared by TUI and ACP; command input and output do not become model messages.

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 compose these bridges — the TUI app, ACP server app, and JSON-RPC SDK-runtime bin — live in examples/ (tui-demo, acp-demo, jsonrpc-demo), each composed over the agent-spine-demo bundle. acp-demo and jsonrpc-demo own boot bins; the tui-demo bundle is booted by the product dsh CLI. 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.
