+- `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。
+- `manage/LlmModels.svelte`、`models-v2.css`：列表测试改用有边框次按钮，编辑/关闭复用图标按钮；详情输入恢复 well 底、line-2 边框、r-sm 圆角及等宽字段；分工下拉接到正确的页面组件样式，补原样状态点和分组边线；底栏测试/保存恢复正常高度。测试框按未测试/成功/失败呈现原有真实状态，已保存测试记录刷新后仍有对应反馈，原始响应仍折叠。
+- `ui/Button.svelte` 只新增可选 iconOnly、aria-label、aria-pressed；旧调用默认行为不变。`ui/icons.ts` 复用注册表加批准的 layers 几何。样式只在这两页原有统一来源修改，颜色/圆角/阴影沿用 token，不改全局按钮变体。
+- `main.py` 仅修 I001 和同文件一处长行；本次触及 Python 文件 Ruff 全过，不处理其他文件存量问题。未新增产品依赖、接口、迁移或配置键。

+# 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.

+1. `cd calliope-web && npm ci && npm run check && npm run lint && npm test && npm run build`
+2. 后端使用已有项目 `[dev]` 依赖，Python ≥3.11；环境放在 `calliope-backend/.venv`。
+3. `python3 scripts/hel842/capture.py --output ./evidence/hel842/delivery`。编排 Python 使用运行环境已有 Playwright；Chromium 系统库可通过 `HEL840_BROWSER_LIBS` 指定。脚本只操作显式指定的隔离目录，固定本机 18740 端口，结束时检查 daemon PID 后清理自有服务。
+4. `python3 scripts/hel840/restart_config.py --output ./evidence/hel842/restart` 验证实际进程重启后分工持久化与假供应商路由。
+5. `python3 scripts/hel842/compare.py --approved ../reference/approved --evidence ./evidence/hel842/delivery --output ./evidence/hel842/comparison`。`--approved` 指向批准 ZIP 的原样解压目录，原件只读。

+HEL-845 日间选中控件定向验证
+
+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`。

+HEL-883 视觉取证；产品代码零修改。
+
+先读 `docs/changelogs/2026-10-26-hel883-visual-investigation.md`。需要环境已有 Python/Playwright/Pillow、后端依赖、Chromium 系统库、Node；不新增产品依赖。
+
+1. 使用 Multica CLI 下载批准 HEL-726、HEL-814 HTML 和 HEL-837 第二版附件；按取证报告核 SHA，保留原件不改。
+2. `read_canvas.py` 仅适用于本卡已授权测试站，默认画布 4，`--board 5` 选择另一画布。通过 `ssh root@192.168.200.15 python3 - --board 4 < scripts/hel883/read_canvas.py` 只读导出到证据目录 `production-board4.json`；另一份存 `production-board5.json`。不读取配置/密钥，也不使用可能 seed 的线上画布 GET。
+3. 构建冻结 `344fede` 与当前头。下载卡内已核验的改前/当前部署包到本地解压，分别指向真实静态根目录。不要在服务器部署或重建。
+4. `python3 scripts/hel883/capture.py --output <证据目录> --baseline <基线构建> --deployed <当前部署包根> --previous <改前部署包根> --references <原件目录>`。原件目录需包含 `canvas-sample.html`；`--only-reference` 只执行部署包同状态样本比较和画布灯箱/持久化回归。
+5. `readonly.py --output <证据目录> --references <原件目录>` 采线上 `/create?kind=image`、`/library` 两个只读入口与批准原件矩阵；原件目录另含 `夜片场-多主题交互样本.html`、`extracted/HEL-837-交互样本-v2.html`。线上所有非只读及 canvas API 都被拦截。
+
+`capture.py` 占用仅本地 18383/15383，开跑先验证端口空闲，暂停隔离队列、LLM/ComfyUI 指向不可用回环地址；唯一媒体夹具明确标注非用户画布，不用于“丰富”产品内容。进程在前台 finally 回收，终止前比对 daemon；隔离目录由 TemporaryDirectory 清理，原始报告/截图/日志保留。参考映射 JSON 含两张测试媒体的截图数据，不含凭据。
+
+输入槽完整回归继续复用 `scripts/hel871/capture.py`，需要单独执行；它的构建、真实上传、焦点/嵌套 Drawer 验证见原 README。源码与部署产物不必共享构建哈希；本卡额外以部署包 127/127 文件与服务端实际静态目录一致证明取证对象。
