+HEL-842：恢复批准第二版的两页控件
+
+基线 `leefer/hel-731-studio-project@7fbcfad29eb1da28059473bc155829b1ada0f979`。批准包 SHA256 `dfe02579065200e8f0edaa3114709fc44286f232fdaa76c34acd3f3814523508`。原件只读，未替换真实日期/路径/计数，不创建面向线上截图的演示文件。
+
+- `routes/library/+page.svelte`、`library-v2.css`：恢复完整/铺满两段和标准/紧凑图标两段；独立按钮支持 Enter/Space，`aria-pressed` 表达选中状态。选择模式复用 Button 的 secondary/scene，补图标及按下状态。恢复查找图标/快捷键提示、8px 工具条间距、类型筛选图标与选中色、底部虚线说明框。保留最新/最早/最大短标签。页面空格预览快捷键避开其他原生按钮，素材格仍能使用预览快捷键。

+# HEL-844: weighted prompt translation and syntax ownership
+
+The shared translate/polish router previously protected whole weighted expressions.
+A valid `(霓虹灯:1.2)` → `(neon lights:1.2)` therefore retried and failed with
+`502 fragment_lost`. Ordinary words inside groups are now editable.
+
+Before calling the existing LLM client, the router replaces each syntax occurrence
+with a unique opaque token scoped to that request. This includes parentheses,
+square brackets, recognized weight suffixes, tags/dialogue spans, CLI parameters,
+and escaped delimiters. Each occurrence has its own identity, even when literal
+weights or tags repeat. The provider receives the mapped prompt and token meanings.
+
+The result must contain exactly the original ordered identities, each once. The
+server rejects added raw syntax, restores tokens itself, then tokenizes again to
+reject newly formed syntax across restored boundaries (for example adding `:2`
+before an encoded closing parenthesis). Nonempty group operands cannot become
+empty. Nested group structure, tag occurrences, and suffix-to-group placement are
+therefore checked by identity and topology, rather than a bag of numeric weights.
+For example, `(猫:1.2), (狗:0.8)` has distinct identities for its two
+suffixes. Exchanging those identities is rejected even though the numeric
+multiset remains `{1.2, 0.8}`. Exchanging identities for two equal `:1.2`
+suffixes in sibling/nested groups is also rejected. Keeping all identities while
+changing `cat` to a semantically wrong word is outside the machine-checkable
+boundary described below.
+
+Text, whitespace and commas between tokens can change; polishing can move words
+within a group without requiring every original text slot to stay occupied.
+
+`protected_fragments` reports the actual literal tags, suffixes, parameters and
+escaped delimiters in source order with duplicates. For `(霓虹灯:1.2)` it is
+`[":1.2"]`; the editable operand is no longer counted as a literal fragment.
+Brackets are verified structurally and do not inflate that list. Existing frontend
+code already uses the returned array length. Tokens never appear in successful
+responses. The existing correction-once / then-502 contract, timeout budget,
+disconnect handling, profile snapshot and model attribution remain in place.
+
+## Machine-checkable boundary
+
+This guarantees syntactic group identity, nesting, literal syntax and multiplicity.
+It cannot prove natural-language equivalence or detect a model silently swapping
+translated meanings between two otherwise valid operand groups. Translation quality
+still needs preview. The parser recognizes the existing bounded angle tags,
+complete `<d>…</d>` spans and `--parameters`, round/square delimiters, escaped
+ASCII delimiters and numeric round-group suffixes. It does not interpret arbitrary
+prompt dialects or repair malformed input; original malformed delimiters are kept.
+Unknown syntax and ordinary names/numbers are not promoted into literal tags.
+Providers unable to preserve identities fail explicitly after one correction.
+
+No endpoint, configuration key, dependency, frontend asset or deployment changed.
+
+## Reproduction and validation
+
+From `calliope-backend`, with the existing dev dependencies:
+
+```sh
+PYTHONPATH=src python3 scripts/verify_prompt_weights.py --output weight-results.json
+ruff check src/calliope/routers/prompt_tools.py tests/test_prompt_tools.py scripts/verify_prompt_weights.py
+```
+
+The script runs the real FastAPI router and LLMClient against an ephemeral local
+HTTP fake supplier, records request/response bodies plus supplier call counts and
+model routing, and exits nonzero if any regression fails. Fixtures isolate SQLite,
+restore settings, disable persistent config writes and close their HTTP servers.
+No paid LLM, GPU or deployment service is contacted. The artifact includes baseline
+failure logs, final raw logs and JSON responses. Frontend check, lint, test and
+production build were run on the unchanged frontend tree; existing acceptance
+screenshots remain applicable to these identical frontend bytes. No browser matrix
+was repeated for this backend-only change. Existing cancellation (including no
+first chunk and blocking fallback), timeout, model routing/defaults, profile freeze,
+long input and error classification tests provide the shared regression coverage.

+HEL-849 修复智能体首页输入区三个原生下拉的展开外观与交互。

+- `AgentWorkspace.svelte` 复用 `PillSelect`：项目/沙盒、任务模型、任务技能仍使用原状态和 API，模型标签显示实际角色绑定；busy 时三个入口禁用。成果区原生选择器、AgentComposer 的 @ 工作流与 / 技能菜单保持原组件。

+- `static/themes.css` 为紧凑款提供唯一尺寸与选中颜色 token。复用已批准的 26px 胶囊、场景色 13% 选中底/60% 描边、主题圆角与阴影；共享组件只有一套渲染规则。
+

+
+共享影响：现有 OmniComposer 的选择器继承上述键盘/定位修复；仓库中该组件仅被未接入路由的 VideoEditWorkspace 引用，本次没有声称对不可达页面完成浏览器验收。当前智能体成果区、任务输入菜单和原会话入口已完成实际回归。后端、模型配置/密钥、提示词、画布业务与依赖未修改；未部署、未合并。

+
+先在 `calliope-web` 执行 `npm ci`、`npm run check`、`npm run lint`、`npm test`、`npm run build`。
+
+在仓库根目录运行：
+
+```sh
+python3 scripts/hel845/verify.py --approved /path/to/approved-unpacked --output /path/to/fresh-evidence --python /path/to/existing-backend-venv/bin/python
+```
+
+编排环境复用现有 Playwright/Pillow，后端环境复用项目依赖，不新增产品依赖。Chromium 系统库不在系统路径时设置 `LD_LIBRARY_PATH`。批准目录须为附件 `01a16e28-f815-7dd1-8661-51fdf26974e8` 原样解压目录；整包 SHA256 为 `dfe02579065200e8f0edaa3114709fc44286f232fdaa76c34acd3f3814523508`。
+
+脚本使用当前仓库源码和真实构建、真实 FastAPI/SQLite/HTTP 假供应商，在本地隔离端口 18740 启动服务，不调用现网或真实付费供应商。四个独立主题上下文、三种窗口、四种适配/密度组合共 48 个状态；每个状态记录 URL、主题、真实背景/文字/图标/阴影/尺寸、键盘焦点和对比度，附上下对照工具条（上批准、下产品）。日间另附四张整页及四张键盘焦点局部图。普通对照图双方均移除焦点，焦点证据单列。
+
+日间断言颜色与阴影逐值相等，文字对比度至少 4.5:1；其余主题在浏览器临时恢复修前两项 day 局部映射，断言与当前构建的控件值相等，不把原样媒体或数据差异当成像素一致。该临时恢复只用于记录 before 值，不修改产品源码。每个窗口验证 Enter/Space、aria-pressed、可见焦点、实际 contain/cover 与密度 class、筛选/排序/查找和选择。
+
+结束先比对 daemon PID，再同步回收确切自有子进程、删除隔离数据库/媒体/配置；保留服务日志、PID 清理记录、原始色值与截图。不得用现有用户数据目录作输出。CSS 单点修复复用 HEL-843 已验收的 MF-1 后端证据，不重跑后端全量，不改旧脚本里的共享页截图结论；本脚本只核素材库 `/library`。
