# OpenSpec Change: enterprise-react-pdf

- **Change ID**: enterprise-react-pdf
- **Package**: `@suaveplan/react-pdf`
- **Category**: react
- **Target path**: `react/media/react-pdf`
- **Status**: PROPOSED
- **Date**: 2026-04-24
- **Reference spec**: `/mnt/s/web/suaveplan/enterprise/react-pdf.md`

---

## Summary

Deliver `@suaveplan/react-pdf` on genesis from scratch at enterprise quality. A React PDF viewer with two tiers: a lightweight `NativePdfViewer` (browser `<object>` + toolbar) and a full `PdfJsViewer` powered by `pdfjs-dist` (text layer, annotations, page count, search, outline). The `PdfViewer` component selects between tiers via a `mode` prop. Genesis fixes the hardcoded `totalPages={0}` bug, adds a real page-count reader, and adds accessibility (screen-reader text layer), Storybook stories, and Playwright E2E.

## New additions for genesis

1. **`PdfJsViewer`** — `pdfjs-dist`-powered: real page count, text layer, search, outline, `PdfError` on load failure.
2. **`NativePdfViewer`** — preserved `<object>` approach (lightweight).
3. **`PdfViewer` `mode` prop** — `'native' | 'pdfjs'` (default `'pdfjs'`).
4. **Bug fix** — `totalPages` is now real (from `pdf.numPages` in pdfjs mode, or `0` with a clear "unknown" label in native mode).
5. **`PdfError`** — codes: `PDF_LOAD_FAILED`, `PDF_RENDER_FAILED`.
6. **Accessibility** — text layer in `pdfjs` mode; `aria-label` on toolbar buttons.
7. **Stories** — `PdfViewer` native + pdfjs modes, loading, error, playground.
8. **Playwright E2E** — load PDF, verify page count displayed, navigate to page 2.
