The result-time diff card sent view.title raw, so a completed edit/write of an absolute in-workspace path flipped the card header back from the relativized `Edit src/b.ts` to the absolute path — the pending card relativizes, the result did not, and tool_call_update.title replaces the header. Apply displayTitle to the result diff arm using the diff path, mirroring the call-side card. Regression test proven red on the unfixed arm. Also record the overwrite diff-basis pre-read as a bounded follow-up (TODO(overwrite-diff-bound) + RFC non-goal): overwriting a large file reads the whole prior text into memory for a UI-only diff.
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) |
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-stdio plugin is the unstructured analogue but lives in support/ because it exists chiefly for the examples and the coverage gate — ui/ is reserved for surfaces shipped as product.
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.
