kingwl f7c289ab1d Merge remote-tracking branch 'origin/master' into feat/plan-mode
Master arrivals re-grafted onto the plan-mode surfaces:
- Package invariant runtime contracts: every package owns ./invariant —
  added the dsh-mode companion (mode/set payload validation: non-empty
  trimmed name), its unit spec, exports/peer wiring, and the mode group in
  the tsconfig invariant paths glob.
- Interception waterfalls gained an AbortSignal parameter
  (agent/prompt-submit, agent/turn-continuation) and ToolExecutionInput.signal
  became required: listeners and test dispatch updated; the exit tool now
  forwards exec.signal unconditionally.
- TUI question dialog: master's position/unanswered header layout kept,
  the plan-review detail block re-grafted between question and answers.
- LSP capability family arrived: lsp tool joins the catalog pin, dsh-lsp
  examples deps beside dsh-mode; lsp-definition snapshot refreshed with
  the mode command and modes advertisement.
- docs/architecture.md and packages/README.md regenerated tables re-grafted
  (ctx.modes row, mode package row) and condensed within word ceilings.
- examples/acp-agent cordis.yml: kept the deployment-owned plan instructions
  (incl. the conversational-agreement sentence) beside master's routed-model
  compaction comment; snapshot expected outputs refreshed keyless and noise
  fixtures restored.

# tui-agent
The full-screen interactive coding agent: DeepSeek V4, local bash and filesystem tools, compaction, subagents, workflows and fresh-agent Ralph iteration, `todo_write`, session modes (`/mode`, plan mode with the reviewed exit), timeout/spill policy, and [`@deepseek-ai/dsh-tui-demo`](../../packages/examples/tui-demo).
## Run it
```sh
pnpm run demo:tui
```
The command needs `DEEPSEEK_API_KEY` in the environment or gitignored repository-root `.env`. Set `RESUME_SESSION_ID` to reopen a persisted conversation under `./.sessions`.
The TUI renders Markdown history, reasoning, tool-owned terminal/diff/generic cards, token totals, and the latest todo list. Long tool bodies keep a head/tail preview; Ctrl+O expands or collapses every card. Enter submits or steers while the agent runs, Ctrl+R toggles reasoning, Escape cancels, and `/help` lists commands. `/model` opens a keyboard selector for the current provider catalog; use Up/Down and Enter, or `/model <model>` and `/model <provider>/<model>` for direct selection. `ask_user_question` opens a wide bottom-left keyboard panel with batch progress and numbered options.
Run `pnpm run demo:code-mode tui` for the Code Mode overlay.
## Composition
[`cordis.yml`](cordis.yml) owns the interactive coding composition directly. [`code-mode.cordis.yml`](code-mode.cordis.yml) includes that leaf and replaces the tool presentation mode while adding the code runtime. Non-interactive automation uses the sibling [headless-agent](../headless-agent/README.md) composition.
## Snapshot tests
`tests/snapshots/<scenario>/session.jsonl` supplies recorded user prompts and model chunks; sibling child logs drive subagents and workflows. The keyless suite executes those scripts through the real loop and tools, then compares readable terminal cell/style output. Use `pnpm run test:snapshot:refresh` for presentation-only changes and `pnpm run test:snapshot:record` with a DeepSeek key when a recorded model journey changes. The implemented [TUI snapshot Agent Note](../../.agents/notes/implemented/testing/2026-07-18-tui-terminal-state-snapshots.md) owns the scenario matrix.
