 ## 报告核对层与独立附录（2026-09-23）
 
-个人报告保留原 Markdown 阅读、目录隔离与 memo 边界；文后独立渲染服务端分盘和事实表。分盘复用 VedicChartSvg 与 chart-grid/chart-card，不使用 float 或负 margin。事实表默认折叠、可键盘展开，横向溢出仅在表格区域滚动，缺数据不补写。Sade Sati 明确缺三轮日期。操作区增加「下载原始附录」，有独立忙态和简短错误提示，不接普通下载 fallback、不增加 spinner。旧缓存不升级、不重算；没有结构化层就不显示占位盘。文案遵守 VOICE：不把可计算写成已验证。

 事实表用中文列名和领域行列呈现，不把引擎路径当行名。主运、分运与小运、SAV 与 BAV、年度位置与 Saham 分为同组子表；缺失的年度行星位置明确说明，不用本命盘替代。机器溯源路径保留在数据中、不渲染。打印或保存 PDF 前自动展开此核对层全部折叠组，完成或取消后恢复原状态；打印解除表格横向滚动裁剪、重复表头，宽 BAV 表仍保留十二星座列。不新增打印入口或等待动画。

 - **Surface:** `--color-canvas-soft` floor; completed rows are paper, other rows canvas, with a warm hairline and `--radius-lg` on the list as a whole. No drop shadow.
 - **Metadata and deletion:** full Chinese date · localized depth · localized themes; unknown IDs remain readable verbatim. Every row has a 44px top-right `⋯` menu containing only 「删除」. It opens the row-local 「确定删除这份报告？」 with 删除 / 取消, never `window.confirm`. Failure stays in that row; success removes it and invalidates list cache. In-flight GET responses cannot resurrect a deleted row.
 - **Width:** 900px centered, matching long-form chat reading. Rows stack at the global 767px cut.
-- **Actions:** “生成完整报告” is the one filled action. A ready row keeps “查看报告” as the primary document action with “分块导出” quiet beside it. The latter links to `/reports/:id#export`; only the ready reader consumes and clears the hash once. Generating copy is one-step (“正在生成报告，大约 10–30 秒”); there is no chapter-count progress. A failed row states the reason in place and offers no second generate entry — the header already has one. Card summary is a deterministic excerpt of the Markdown 「摘要」 section, stored on the cover document at generation time.
+- **Actions:** “生成完整报告” is the one filled action. A ready row keeps only “查看报告”; export is selected inside the reader so the list does not duplicate that action. Generating copy is one-step (“正在生成报告，大约 10–30 秒”); there is no chapter-count progress. A failed row states the reason in place and offers no second generate entry — the header already has one. Card summary is a deterministic excerpt of the Markdown 「摘要」 section, stored on the cover document at generation time.
 - **States:** loading, empty, populated, generating, ready, failed, unauthorized, list error. First-screen loading uses `SecondaryPageShell` waiting copy 「报告列表还没拿到。」 — never a spinner, skeleton, or 「正在加载」. Export is local to the ready reader's drawer and never starts a second writing flow or fetch. Download failures remain in the open drawer; only success closes it and emits a toast. A missing Markdown appendix is an old report: the detail page asks the reader to regenerate.
 - **Accessibility:** generate, refresh, and row actions are 44px. The generating row's chip is a live region; a failed export is an alert.
 
 ### Personal report reader
 
-- **分块导出抽屉 (2026-09-24):** native modal `<dialog>`, bottom-aligned on all screens, app colours only, `min(760px, 92% of available content width)`, at most 70vh/70dvh, offset past the expanded/collapsed sidebar. Header and single export footer stay visible; the block list scrolls, two columns at the existing 860px breakpoint. Escape, backdrop or 关闭 dismisses; focus returns without scrolling. All controls have 44px targets. No spinner, clipboard or extra fetch.
+- **分块导出对话框 (2026-09-24):** native modal `<dialog>`, bottom-aligned below 860px and centered at ≥860px, app colours only. Desktop is viewport-centered (`inset: 0; margin: auto`) regardless of sidebar state, width `min(720px, 92vw)`, max-height 80vh, with full `--radius-lg` corners. Its flex panel is capped at `calc(80vh - 2px)` to reserve the dialog border; desktop rules follow the narrow-screen dvh upgrade so 70dvh cannot override them. Below 860px the content-column offset, bottom alignment and at most 70vh/70dvh remain unchanged. Header and single export footer stay visible; the block list scrolls, two columns at the existing 860px breakpoint. Escape, backdrop or 关闭 dismisses; focus returns without scrolling. All controls have 44px targets. No spinner, clipboard or extra fetch.
 - **Export selection:** default 常用 selects every body block from the single outline's lossless source slices (lead = 摘要); 全部分盘 and 仅核对表 replace the selection. Manual toggles clear preset highlighting. 全选 / 取消全选 works across all groups; zero selected disables export. Counts are actual Unicode code points in serialized block text, including SVG markup, not approximate prose counts.
 - **Export content:** full body alone remains byte-identical to the retired ordinary Markdown export. Selected chart/table blocks append new content; selecting all groups is not byte-identical to body-only. D13 requires safe SVG in each chart, reusing the projected engine SVG or the existing hook-free Vedic drawing; offline fallback uses readable monochrome glyphs/legend and presentation attributes. No chart JSON fences or internal audit fields. Fact-table labels/precision/subtables match the reader. Full body uses the historical filename; excerpt adds `-节选`. The existing downloader appends `.md`.
 
-- **Structure:** inside the app shell, like every other secondary page — `/reports/[reportId]` was the last standalone full-screen route, and opening a report used to drop the reader out of the app entirely. 「个人报告」 sits in the 46px header; below it the reader owns its own scroll boundary, carrying the sticky screen chrome (back, secondary print, primary “分块导出”, plus the existing raw appendix download) and then the longform Markdown body beside a persistent TOC rail. Every phase — loading, generating, timed-out, and each error — renders inside the same shell, so the way back is always the rail. The five-chapter writer document is storage-only and is not rendered. Reports without Markdown show “旧版本报告，请重新生成”.

 - **TOC rail:** a persistent right-hand column built from the outline's own `##`/`###` ids — no second slugger, and nothing that touches the chart-grid rehype pass. It is sticky under the report's own action bar, highlights the section in view via `IntersectionObserver`, and marks it with `aria-current="location"` plus a 2px `--color-action` bar. Placement is explicit (`grid-column: 2`) rather than DOM-ordered, so the narrow-screen drawer can stay first in the source. Below 860px the rail is gone and what remains is the collapsed 「目录」 drawer.
 - **Paper stays paper:** the rail reads in the app palette because it is chrome. `--report-paper` / `--report-rule` / `--report-accent` are the document's own, deliberately out of step with the app accent, and nothing in this surface puts them on chrome or takes chrome colour onto the page. D11, continuing D3.
 - **Surface:** page floor `--color-canvas-soft`; the Markdown article is a `--color-canvas` sheet with a hairline and `--radius-lg`. Print flattens the sheet, hides chrome and the TOC, and pins the light palette.
