v2.0.1

Chat streaming and ordering

• One queue per turn - every stream delta, tool result and turn boundary now goes through SerialEvents, which drains in submission order on the main thread; sequence numbers are assigned during the drain and ChatState keeps a stable order, so a finished message can no longer overtake its last delta and flash prose into the answer area.
• Turn pipeline - the streaming draft moved into ChatTurnPipeline, which owns the buffers, the assistant message and every seq advance, and drops events from a generation that has already lost the conversation; opening, creating or deleting a conversation also stops the running loop first, so late events cannot leak into the new list.
• Answer versus process - live prose stays inside the process panel until the model message completes; only a completed message without tool calls becomes the answer, which removes the flash-then-fold of the review block.
• Failure surface - a failed turn persists an ERROR content block instead of plain prose, keeps partial output as the completed body and renders the reason as normal text (16sp, body color, no Markdown).
• Verbatim provider errors - HttpModelClient reads the error stream and reports HTTP <code> followed by the response body; the failure formatter no longer rephrases it, so the actual 401/404/429/500 payload reaches the chat.
• Stream retry - a transient model failure retries up to three times with an 800 ms delay, the turn pipeline is told which attempt is running, and a retry clears the half-written draft instead of appending to it.

Process and status indicators

• Shared dot matrix - DotMatrix and DotMatrixSpinner in ui-kit replace every ProgressBar: the working row, the process panel and the tool cards now share one 3x3 walk and one 1.5 s cycle, and all of them honour the system animation scale.
• Process panel - opens itself while a turn streams and folds when it ends; a manual toggle is stored as an absolute choice, so a default that flips later never reverses it, and pending approvals count as active too.
• Tool card spacing - consecutive calls in a group and nested agent cards use a 2dp gap, so a run of calls reads as one list instead of separate cards.

Tools

• web_fetch - new built-in tool that fetches one page and returns readable text: HTTPS only plus HTTP for loopback/emulator hosts, 2 MB response cap, HTML reduced to text with scripts and styles stripped, 12k characters by default and 30k maximum; the tool list uses the new FETCH/GLOBE glyph.
• Lenient tool arguments - ToolJsonRepair repairs what models actually emit: fences, prose before the object, smart or single quotes, unquoted keys, comments, Python literals, raw newlines, trailing commas, truncation at the token limit, a double-encoded arguments string and a single-object array wrapper. Mutating tools still reject truncated payloads instead of writing half a file.
• Structured schemas - tool schemas and MCP input schemas are built through ToolSchemaBuilder/org.json; a source guard now rejects hand-written JSON object literals in main sources.
• Mode filtering - agent mode keeps every tool family except phone control, which stays exclusive to control mode.

Context

• Manual compaction - "Compact context" in the chat menu now performs a real compaction: it summarizes everything except the recent tail and reports done, insufficient, no model, busy or failed.
• Compaction marker - a successful compaction appends a compact row, rendered by the previously unused CompactBlockView.
• Prompt asset - the compaction instruction comes from the prompt catalog (CONTEXT_COMPACTION) instead of an English string compiled into the compactor.

Workspace and attachments

• Workspace provider - WorkspaceDocumentsProvider exposes files/workspace through SAF (.workspace.documents), and the workspace card gains "Share with other apps", handing the root to another app with read/write grants.
• CJK folder names - WorkspaceNames.folder only replaces characters that are illegal in a path segment, so Chinese, Japanese and Korean names stay readable instead of collapsing to -.
• Drawer refresh - the project header and the file tree reload when the workspace changes, and opening the drawer always rebinds them.
• Photo Picker - image and video attachments use the system Photo Picker on API 33+ with the SAF picker as fallback; attachment names prefer DISPLAY_NAME before the MIME suffix because Photo Picker URIs carry no extension.

SkillHub

• Both payload shapes - the store parses the flat list payload (description, downloads, ownerName, iconUrl, stars, verified, category, labels.requires_api_key) and the nested detail payload (stats, owner); sorting uses sortBy with order=desc.
• Real icons - SkillIconLoader downloads artwork off the UI thread, caches 24 bitmaps, downsamples to 96 px, validates the URL against an HTTPS allow-list with a 4 MB cap, and tags the view so a late bitmap cannot land on a rebound row.
• Legacy card - artwork, title with a verified tag, author, category tags, a two-line description, downloads/stars/version and a chevron.

Extensions and multi-select

• AI agent writer - "Let AI write" now works: a bottom sheet takes a natural-language request, generation runs on the IO scheduler through AgentDraftGenerator and the new AGENT_DRAFT prompt, unknown tool names are dropped against the catalog the page passes in, and incomplete drafts are rejected instead of filling the form with empty fields.
• Selection bar - SelectionBar replaces the inline bar with count, copy, share and close; copy and share build a plain-text transcript in timeline order, tapping a message toggles its selection, and the placeholder "select and export" row is gone from the more menu.

Interface polish

• Drawer tabs - tab glyphs grow from 16dp to 24dp with an 8dp gap, and the inline icon button no longer reserves a minimum size.

• Switches - Material switch tinting (white thumb on the accent track when on, gray on a light track when off), so an enabled switch no longer reads as disabled.

• Long-press bar - action buttons lose their 4dp right margin.

Engineering

• Schema builders - database statements are grouped into conversation, settings/model, extension and project builders instead of one long method.
• Composition root - AppGraph construction is decomposed into focused steps without introducing new dependency bags.
• Build - Gradle configuration cache is enabled.

Tests

• New SerialEventsTest, ChatStateTest, ToolJsonTest, WebFetchToolTest, AgentDraftGeneratorTest, SkillHubApiTest and WorkspaceNamesTest; extended TurnAssemblerTest, ContextCompactorTest, ToolModesTest, HttpModelClientProtocolTest, BuiltinToolsTest and SourceHygieneTest.

Release

• Version 2.0.1 (versionCode 47); the release workflow still builds and publishes both the slim and local variants.

中文

聊天流式与顺序

• 单队列事件 - 流式增量、工具结果与回合边界统一进入 SerialEvents，在主线程按提交顺序排空；seq 只在排空过程中分配，ChatState 保持稳定排序，完成的消息不会再越过最后一段增量，正文也不会先闪进答案区再折叠。
• 回合管线 - 流式草稿移入 ChatTurnPipeline，由它独占缓冲、助手消息与每一次 seq 推进，并丢弃已经失去当前对话的旧生成事件；打开、新建、删除对话前会先停止正在运行的循环，迟到的回调不会写进新会话。
• 答案与过程分离 - 流式正文只进入过程面板，只有已完成且没有工具调用的消息才成为正式答案，消除了审阅块闪现后再折叠的问题。
• 失败展示 - 失败回合改为持久化 ERROR 内容块，部分输出保留为完成正文，失败原因以普通文本渲染（16sp、正文色、不做 Markdown）。
• 原始错误透出 - HttpModelClient 读取错误流并输出 HTTP <code> 加响应体，格式化层不再改写，401/404/429/500 的原始内容直接进入聊天。
• 流式重试 - 可恢复的模型失败最多重试 3 次、间隔 800ms，回合管线会收到当前重试次数，重试前清空半截草稿而不是继续追加。

过程与状态指示

• 共享点阵 - ui-kit 的 DotMatrix / DotMatrixSpinner 取代全部 ProgressBar：工作状态行、过程面板与工具卡片共用同一套 3×3 走位和 1.5s 周期，并统一遵循系统动画缩放。
• 过程面板 - 流式期间自动展开、回合结束后折叠；手动开关保存为绝对状态，后续默认值翻转不会反转用户选择，待确认状态同样视为进行中。
• 工具卡间距 - 工具组内的连续调用与嵌套 Agent 卡片改为 2dp 间距，一组调用读起来是连续列表而不是分散卡片。

工具

• web_fetch - 新增内置工具，抓取单个网页并返回可读正文：仅允许 HTTPS（回环/模拟器地址例外）、响应上限 2MB、剥离脚本与样式的 HTML 转文本、默认 12000 字符、最大 30000 字符；工具清单使用新的 FETCH/GLOBE 图标。
• 宽松参数解析 - ToolJsonRepair 修复模型实际输出的写法：代码围栏、对象前说明文字、中文/单引号、未加引号的键、注释、Python 字面量、字符串内原始换行、尾逗号、token 上限截断、二次编码的 arguments 与单对象数组包装。写操作工具仍拒绝截断参数，不写入半截文件。
• 结构化 Schema - 工具定义与 MCP 输入 Schema 统一通过 ToolSchemaBuilder / org.json 构造，源码守卫禁止 main 源码出现手写 JSON 对象字面量。
• 模式过滤 - Agent 模式保留除手机控制外的全部工具族，手机控制只在 Control 模式注入。

上下文

• 手动压缩 - 聊天菜单的「压缩上下文」现在执行真实压缩：除最近尾部外全部摘要，结果区分完成、无需压缩、缺少模型、生成中与失败。
• 压缩标记 - 压缩成功后追加一行压缩记录，由此前未被使用的 CompactBlockView 渲染。
• 提示词资产 - 压缩指令改由提示词目录（CONTEXT_COMPACTION）提供，不再把英文提示写在压缩器代码里。

工作区与附件

• 工作区 Provider - WorkspaceDocumentsProvider 通过 SAF 暴露 files/workspace（.workspace.documents），工作区卡片新增「共享给其他应用」，把根目录连同读写授权交给其他应用。
• 中文目录名 - WorkspaceNames.folder 只替换路径段非法字符，中/日/韩名称保持可读，不再退化成 -。
• 抽屉刷新 - 工作区变化后刷新项目标题与文件树，打开抽屉时也会重新绑定。
• 系统图片选择器 - 图片与视频附件在 API 33+ 走系统 Photo Picker，失败回退 SAF 选择器；附件命名优先取 DISPLAY_NAME，再退回 MIME 后缀，因为 Photo Picker 的 URI 没有扩展名。

SkillHub

• 两种返回结构 - 商店同时解析扁平列表结构（description、downloads、ownerName、iconUrl、stars、verified、category、labels.requires_api_key）与嵌套详情结构（stats、owner）；排序改用 sortBy + order=desc。
• 真实图标 - SkillIconLoader 在 UI 线程之外下载图标，缓存 24 张位图并降采样到 96px，按 HTTPS 白名单校验地址、单文件上限 4MB，并给目标 View 打 tag，避免迟到的位图落到已复用的行上。
• 旧版卡片 - 图标、带认证标记的标题、作者、分类标签、两行描述、下载量与收藏数/版本，以及右侧箭头。

扩展与多选

• AI 写 Agent - 「让 AI 写」已可用：底部面板接收自然语言需求，生成在 IO 调度器上通过 AgentDraftGenerator 与新提示词 AGENT_DRAFT 完成，未知工具名按页面传入的清单过滤，字段不全的草稿直接拒绝，不往表单里填空值。
• 多选操作栏 - SelectionBar 取代原行内操作栏，提供计数、复制、分享与关闭；复制/分享按时间线顺序生成纯文本记录，点击消息即可切换选中，更多菜单里的「选择并导出」占位行已移除。

界面细节

• 抽屉标签 - 标签图标从 16dp 增至 24dp、间距改为 8dp，内联图标按钮不再保留最小尺寸。
• 开关配色 - 开关改用 Material 配色（开启时白色滑块 + 主题色轨道，关闭时灰色滑块 + 浅色轨道），开启状态不再读成禁用。
• 长按操作条 - 操作按钮移除 4dp 右边距。

工程质量

• 建表语句 - 数据库建表语句拆分为会话、设置与模型、扩展、项目四个构建方法，不再挤在一个长方法里。
• 组装根 - AppGraph 的构造过程拆分为多个聚焦步骤，未引入新的依赖包。
• 构建 - 启用 Gradle 配置缓存。

测试

• 新增 SerialEventsTest、ChatStateTest、ToolJsonTest、WebFetchToolTest、AgentDraftGeneratorTest、SkillHubApiTest、WorkspaceNamesTest；扩展 TurnAssemblerTest、ContextCompactorTest、ToolModesTest、HttpModelClientProtocolTest、BuiltinToolsTest 与 SourceHygieneTest。

版本

• 版本号 2.0.1（versionCode 47）；Release 工作流继续同时构建并发布 slim 与本地版。
