kingwl b29aeb1847 fix(stdio): /mode is reserved even while a question prompt is active
Review finding at the seam of two surfaces this branch added to the
same stdin: with an ask_user_question (or plan-review) prompt active,
the line handler dispatched every line as the answer first, so
'/mode plan' typed mid-question was recorded as free-text feedback —
model-visible in the tool result — and the mode never changed. Command
handling now runs before answer dispatch: the command executes, the
question stays pending and still owns the next non-command line. A
literal '/mode…' free-text answer is the trade-off deliberately spent —
a swallowed command that becomes review feedback costs far more than
that contrived answer shape.

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-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-agent/ Terminal stdio chat APP: the agent-core spine + console logger + readline UI + a pre-created main agent, with a bin (composition + bin)
acp-agent/ ACP server APP: the agent-core spine + JSONL persistence + the acp bridge (no stdout logger), with a bin (composition + bin)
app-boot/ Shared boot glue for the two 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 readline UI is the unstructured analogue of the acp bridge and lives INSIDE the stdio app (the stdio-chat module of stdio-agent/): it is scaffolding for that one front door, not an independently swappable integration, so it carries no package boundary of its own.

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. The seam remains provider-neutral (ctx.userInteraction), while the tool is the model-facing consumer and the app/bridge packages provide concrete providers.

stdio-agent and acp-agent are the two app packages: each composes the core/agent-core spine with its coupled front-door cluster (and owns the boot bin), so a leaf cordis.yml is the swappable backends plus one app entry plus any optional product tools. They live in ui/ because each IS a user-facing front door; the stdout-purity coupling (logger vs. no logger) becomes a property of the artifact rather than a leaf convention.
