AgentCanvas v0.2.0

A redesign of the editor around a single canvas, a full set of visual styles, and a
new landing page.

Added

• Canvas-first editor. The window is the canvas and the chrome floats on it: a
  Figma-style rail, a layer tree, zoom, a 4:3 page, a draggable left column, and
  edit / delete controls on every module.
• Build from empty. The canvas opens empty and fills in as components are picked;
  the conversation is composed from your picks one turn at a time, and the event flow
  is drawn as a vertical axis with coverage ticks.
• Thinking components. Thinking and Thought process are separate stages, with
  eight motions, expand behaviour, a "Thought for N seconds" display style, and three
  text-loading modes (smooth stream, typewriter, chunked) with a live speed control.
• 13 visual styles on one skin engine — Native, Ink Wash, Quest, Sketch, Retro,
  Tech and more — each with its own palettes, icons, avatars and component materials.
• Selection island above the canvas: component and event-flow counts, what is
  left to fill in, clear and undo.
• Model panel with provider logos and a model picker in the composer.
• Avatars: four default user avatars plus upload; pointer-following 3D avatars.
• Approvals show Allow / Always allow / Deny / Cancel, and both inline and
  external approvals can be cancelled.
• Landing page rebuilt: a style browser that scales to dozens of styles, an
  anatomy of the canvas, an event-to-component wiring diagram, providers, and the
  export tree.
• README demo re-recorded as a 25-second English tour of the real editor
  (npm run capture:tour).
• CHANGELOG and automatic GitHub releases from version tags.

Changed

• The output area's tabs are a segmented control with underline tabs whose corners
  follow the style.
• The send button is one 32px icon key in every style.
• The brand menu's Home opens the landing page, asking first if the canvas has
  unsaved picks.
• Esc leaves run mode; the output area maximises in place.

Fixed

• Exported projects carry the editor's icon picks, so an export keeps its style's
  avatars instead of falling back to Native's.
• The editor's hover highlight no longer ships inside exported apps.
• Exported projects include unifiedDiff.ts and typecheck again.
• Icons no longer leak into other styles after a style switch; low-contrast text in
  several themes, clipped hover highlights and an empty canvas reading 11% complete
  are fixed.
• The editor shows its real version number (it read v0.1.0 through v0.1.1).

更新

• Pi runtime：编辑器和导出的脚手架都带上内置 Pi runtime，真实运行会按当前编排渲染界面。文档写明了这套 runtime 能做到哪里、哪里仍然不行。
• Skin engine：主题预设收成一个 skinId（family + variant）。配色和布局配方由 SkinEngine 统一解析，配置器、预览和导出的脚手架走同一条路径。
• 输出区：Markdown 预览补齐围栏代码、KaTeX 公式和 Mermaid 图。导出的包会带上 katex 和 mermaid。
• 应用结构：编辑器从单个大组件拆成 MVVM 分层（状态机、viewmodel、projection）。边界写在 docs/APP_ARCHITECTURE.md。
• 真实模型：Anthropic 会话会声明与 OpenAI 兼容路径相同的工具集，现场会话能渲染工具卡片。Provider thinking 按渲染策略分类，不把原始推理链直接摊开。
• 审批：各界面里，审批请求都出现在 composer 上方。
• 语言：加入日语，locale 层不再只容纳两种语言。
• 落地页与 README：独立品牌标记和配色、指针下散开的点阵、英文 hero 视频；README 用编辑器操作录像代替静态截图。
• 导出说明：docs/CONNECTING_AI.md、生成的 README 和导出的 AGENTS.md 说明如何用真实模型驱动导出的应用，并写明导出包本身还不能直接调用模型。

修复

• 工具 diff：用 old/new 片段生成真实 unified diff，不再伪造 “previous implementation” 行。.diff / .patch 标签着色，只剩一个输出页时也可以关闭。
• 运行中的宿主控件：运行进行时禁用 provider / model 选择和浮动 provider 面板。单条工具结果和产物限制在 10 万字符。会话侧栏按真实日期分组。
• Pi turn 收尾：取消或失败的 turn 一定会进入终态。空流和 run.error 记为失败，而不是成功提示。停止运行会在本地关上未完成的文本、工具块和滞留的审批层。
• 开发服务器：provider 代理和 Pi 控制面拒绝跨源请求，代理请求体限制 10MB。“始终允许”只在当前会话内有效，新会话会清掉。auto 模式下，会改动文件的非 shell 工具仍要询问。运行中的 /config 返回 409。
• 会话侧栏：导出的脚手架不再填入编造的历史会话。没有会话存储时不显示列表。
• 下拉菜单：长菜单保持在视口内。
• 版本号显示：界面上的版本号更正为当时的发布版本 v0.1.0。
• 英文文案：英文 composer 占位符和英文编辑器导览录像与 README 对齐。本地环境覆盖文件不再入库。

文档

• 记录 Pi runtime 的接入方式，以及导出应用如何接上真实模型。
• 注明项目贡献者。

Updates

• Pi runtime: The editor and exported scaffolds include the built-in Pi runtime, and a real run renders the UI that was composed. The docs state where this runtime works and where it still stops.
• Skin engine: Theme presets resolve through one skinId (family + variant). SkinEngine resolves tokens and the layout recipe on one path, shared by the configurator, the preview, and the exported scaffold.
• Output: The markdown preview now renders fenced code, KaTeX math, and Mermaid diagrams. Exported packages ship katex and mermaid.
• App structure: The editor is split out of one large component into an MVVM layer (state machine, viewmodel, projection). The boundaries are documented in docs/APP_ARCHITECTURE.md.
• Live models: An Anthropic session advertises the same tool set as the OpenAI-compatible path, so a live session renders tool cards. Provider thinking is classified under the render policy and raw chain-of-thought is not shown in ordinary UI.
• Approvals: On every surface, the approval request sits above the composer.
• Locales: Japanese is included, and the locale layer now holds more than two languages.
• Landing page and README: A dedicated brand mark and palette, a dot field that scatters under the pointer, and an English hero video. The README leads with a recording of the editor in motion instead of a still.
• Export docs: docs/CONNECTING_AI.md, the generated README, and the exported AGENTS.md explain how to drive an exported app with a real model, and state that the exported package itself still cannot call a model.

Fixes

• Tool diffs: Diffs are built from old/new snippets as a real unified diff, instead of a fabricated “previous implementation” line. .diff / .patch tabs are colored, and the last output tab can be closed.
• Host controls during a run: Provider and model pickers, and the floating provider panel, stay disabled while a run is active. Each tool result and artifact is capped at 100,000 characters. The session sidebar groups sessions by the real date.
• Pi turn terminal state: A cancelled or failed turn always reaches a terminal state. An empty stream and a run.error are reported as failures, not as a success toast. Stopping a run closes unfinished text, tool blocks, and any stranded approval locally.
• Dev server: The provider proxy and the Pi control plane reject cross-origin requests, and proxy bodies are capped at 10MB. “Always allow” lasts only for the current conversation and is cleared by a new session. In auto mode, mutating non-shell tools still ask. /config returns 409 while a run is active.
• Session sidebar: Exported scaffolds no longer show fabricated conversation history. With no session store, the list is omitted.
• Select menus: Long menus stay inside the viewport.
• Displayed version: The version shown in the UI was corrected to the release then current, v0.1.0.
• English copy: The English composer placeholder and the English editor-tour recording match the README. Local environment overrides are no longer committed.

Docs

• Documents how to connect the Pi runtime, and how to drive an exported app with a real model.
• Notes project contributors.
