The automation bridge inherited two master-era assumptions the message machine no longer honors. A prompt blocked at pre-turn admission opens no turn, so no turn/end could ever settle it — the bridge now watches whenIdle() and reports a turnless slot as cancelled (the disposed-agent guard moved to a registry identity check before send). A failed turn no longer rejects at its turn/end either: agent.retry() closes the failed turn and opens a successor on the same history, so the bridge holds the terminal error and lets a retry-triggered turn/start adopt the prompt, rejecting only at quiescence with no successor. Also: refresh the empty-response-retry fixture for retry-as-turn logging, adapt master-side tests to the unified send()/UserMessageData API and registry-fact disposal, resync the doc pairs both sides touched, trim architecture.md back under its word ceiling, and regenerate the event and persistence catalogs.
Examples
Runnable demos (not workspaces) that showcase how the harness is wired. Each example is a thin leaf: a cordis.yml that picks swappable backends, loads one app package, and may add optional product tools. The composition and boot glue live in @deepseek-ai/dsh-tui-demo, @deepseek-ai/dsh-cli-demo, @deepseek-ai/dsh-acp-demo, and their shared @deepseek-ai/dsh-agent-spine-demo bundle. There is no start.ts; the terminal demo:* scripts boot through the dsh CLI (which mounts the tui-demo bundle), and the headless/ACP scripts invoke the cli-demo/acp-demo bins.
headless-agent
A non-interactive agent demo that accepts one positional task, runs one complete model/tool turn on the @deepseek-ai/dsh-cli-demo app, persists a fresh session, prints text, json, or stream-json, and exits.
Run with: pnpm run demo:headless "task" (needs DEEPSEEK_API_KEY). See headless-agent/README.md for the output contract, safety boundaries, and snapshot suite.
tui-agent
The interactive coding agent: DeepSeek V4, filesystem and bash tools, subagents, workflows, todo_write, compaction, and the full-screen TUI. It is also the home of TUI PTY and snapshot scenarios.
Run with: pnpm run demo:tui (needs DEEPSEEK_API_KEY). Run its Code Mode overlay with pnpm run demo:code-mode. See tui-agent/README.md for controls and composition.
jsonrpc-agent
An unattended coding agent driven through the Python SDK: JSON-RPC stdio, foreground-only bash, read / write / edit, one foreground subagent, todo_write, JSONL persistence, and compaction. It excludes terminal UI, stdout logging, approvals, skills, and background task controls. See jsonrpc-agent/README.md.
cordis-agent
The self-referential demo: the coding spine plus @deepseek-ai/dsh-tool-cordis, whose three tools (cordis_inspect / cordis_mount / cordis_unmount) let the agent inspect the live cordis runtime it runs inside, mount model-written plugins into it (an event listener, a brand-new tool for itself, or a service another mount injects), and dispose them again — all dynamic mounts grouped under one cordis-dynamic fiber subtree. The ctx.fs/ctx.web services ride along provider-only, as the capabilities those plugins build on.
Run with: pnpm run demo:cordis (needs DEEPSEEK_API_KEY). See cordis-agent/README.md for the staged demo script and the toolset Agent Note for the design and sandbox caveats.
acp-agent
An agent exposed as an Agent Client Protocol (ACP) automation server over JSON-RPC stdio, via @deepseek-ai/dsh-acp-demo. Programmatic clients create fresh sessions, send text prompts, consume committed assistant text, answer one-shot permission requests, and cancel work. It owns the ACP keyless snapshot suite.
Run with: pnpm run demo:acp (needs DEEPSEEK_API_KEY); pnpm run demo:code-mode acp boots the same server in Code Mode via the code-mode.cordis.yml overlay. See acp-agent/README.md for the protocol and snapshot-test contracts.
The default cordis.yml composes @deepseek-ai/dsh-sandbox-local, @deepseek-ai/dsh-bash-sandbox, and @deepseek-ai/dsh-user-approval. workspace-write confines bash and filesystem mutations to each session workspace; a wider retry becomes a one-shot machine permission request over ACP.
