Chinesezjc cc1bba31d8 fix(tool-web): align fetch card truncation, drop view content copies, sync card docs
Address the code-review bot findings on the web result card:
- web_fetch's card truncated now derives from the shared renderFetchOutput
  helper, matching the effective truncation the model-facing text reflects
  (provider cap, source cut, or output cap), instead of the provider-only flag.
- Drop the redundant content copy from both web result views; a UI without the
  web capability falls back to the raw tool/result content. Narrow the TUI
  transcript view.content access accordingly.
- Set the result-state title from the call args (query/url) so a window-
  truncated replay keeps a title.
- Project meta from the seam result types rather than hand-rolled value types.
- Sync the card vocabulary across core tools README, docs/core-data-structures,
  the adding-a-tool cookbook, and the tool-web package README (both languages,
  re-recorded pairings); regenerate the cordis api-catalog and cordis-inspect
  snapshot; revise the Agent Note.

acp-agent example

English | 中文

Automation-oriented Agent Client Protocol server over JSON-RPC stdio. It is intended for parent agents, subagent providers, and other programmatic clients, not as the product UI.

pnpm run demo:acp             # needs DEEPSEEK_API_KEY (repo-root .env or env)
pnpm run demo:code-mode       # same protocol with the Code Mode tool transport

The leaf loads the ACP app, DeepSeek adapter, sandboxed bash and filesystem stacks, one-shot approval policy, compaction, subagents, workflows, hooks, a derived session-query index, and repeat guard. The app creates one fresh agent per session/new, persists sessions to JSONL, and keeps stdout protocol-pure. session-query.cordis.yml explicitly opts into the workspace-authorized query tools and generic timeout/spill policies for their dedicated snapshot; fs.cordis.yml adds spill storage for filesystem scenarios, code-mode.cordis.yml adds run_code and its generated TypeScript SDK, and web.cordis.yml adds the web seam, the local fetch provider, web_fetch, and a loopback HTML fixture server for the web-fetch snapshot.

Protocol channel

Stdout carries only newline-delimited ACP JSON-RPC. @deepseek-ai/dsh-acp-demo installs no stdout logger; leaf additions must use stderr for diagnostics.

The automation contract — supported methods, baseline prompt content, committed-text output, and the intentionally absent UI surfaces — lives in @deepseek-ai/dsh-acp.

Session workspaces and permissions

Each session/new supplies an absolute cwd. Sandboxed bash and filesystem mutations resolve workspace-write against that session cwd, so concurrent sessions can use separate project roots; platform temporary roots remain shared writable scratch space (sandbox contract). DSH_PERMISSION_MODE selects workspace-write or danger-full-access for deployment and tests.

Under workspace-write, a model retry requesting wider sandbox access triggers session/request_permission with allow_once and reject_once. The client decides programmatically; dismissal or an unavailable answer fails closed. The selected outcome applies only to that retry and is recorded through the normal tool-result/audit path. The server never exposes a permission picker or persists client policy.

Snapshot tests

This example owns the ACP snapshot suite. It boots the real automation server, replays committed model streams through dsh-llm-replay, and compares both normalized protocol output and re-persisted session logs. Recording uses the real model; refresh reuses committed replay input. Overrides cover throw/hang behavior, and optional workspace/ fixtures seed world-state checks.

Most scenarios pin backend behavior rather than ACP-specific behavior; the automation-only ACP decision owns why that coverage remains transport-coupled.
