imccyu adbba0deb2 fix(system-prompt): reject a toolOrder that names an unregistered tool
Review follow-up (#196): a listed name with no registered tool was silently
ignored; misconfiguration must block work instead. The check lives in the
assembly — the earliest moment the registered tool set exists (tool plugins
register after the service constructs) and the only universal one (cordis has
no "all plugins loaded" event; registrations change at any time). assemble()
is now async so the throw surfaces as a rejection rather than a synchronous
escape from a Promise-returning method.

Blast radius, pinned by a loop-level test: the rejection reaches the turn's
outer catch — the turn closes balanced with an `error` reason, agent/error
mirrors it, no step opens, no request/header is logged, no request reaches
the adapter, and the agent returns to idle; every turn fails identically
until the config is fixed. A boot-time validation pass was considered and
rejected (recorded in the RFC). The general principle — misconfiguration
fails loud, never a silent skip — is added to AGENTS.md.

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)
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.

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.
